[0005] Patent Document 1: International Publication No. 2019 / 044826 Summary of the invention

[0006] Problems to be solved by the invention

[0007] However, conventionally, sufficient consideration has not been given to arranging the vibrator at an appropriate position, and it is required to arrange the vibrator at an optimal position for the seated person, for example, by optimizing the positional relationship between the seat frame, the shape of the cushion, and the pressure-receiving member.

[0008] Furthermore, as another problem, efforts must be made to more appropriately transmit the vibration generated by the vibrating body to the seated person.

[0009] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a vehicle seat in which a vibrating body is arranged at an appropriate position.

[0010] Technical means of solving problems

[0011] The problem is solved by the following manner, that is, according to the vehicle seat of the present invention, it is a vehicle seat, including: a frame constituting a skeleton; a pressure-bearing member arranged on the frame to bear the load of the occupant; and a cushion member covering the pressure-bearing member, in which at least one vibrating body generating vibration is provided, and the vibrating body is arranged at a position where at least a part of the vibrating body does not overlap with the pressure-bearing member when the vehicle seat is viewed from the front or from above.

[0012] According to the vehicle seat of the present invention constructed as described above, a part of the vibrator is arranged at a position that does not overlap with the pressure-receiving member when viewed from the front or from above, so when the occupant is seated, the vibrator does not interfere when the occupant sinks into the cushion member. Therefore, it is possible to provide a vehicle seat in which the vibrator is arranged at an appropriate position.

[0013] Furthermore, in the above-mentioned structure, the pressure-receiving member may be provided in the frame so as to be movable within a predetermined range, and the vibrating body may be arranged outside the predetermined range.

[0014] By arranging the vibrator outside the movable range of the pressure-receiving member, the vibrator does not interfere with the pressure-receiving member, and an increase in discomfort can be suppressed.

[0015] Furthermore, in the above configuration, an opening may be formed in the pressure receiving member, and the vibrator may be arranged at a position overlapping the opening when the vehicle seat is viewed from the front or from above.

[0016] By arranging the vibrator so as to overlap with the opening, it is possible to suppress the discomfort caused to the seated person.

[0017] Furthermore, in the above configuration, a through hole for absorbing deformation of the pad member may be formed in the pad member, and the vibrator may be arranged at a position overlapping the through hole in the seat width direction.

[0018] By arranging the vibrating body at a position overlapping with the through hole in the seat width direction, deformation of the pad member caused by the vibrating body can be absorbed.

[0019] Furthermore, in the above configuration, a transverse insertion hanging groove extending in the seat width direction may be formed in the pad member, and the vibrator may be arranged below or in front of the transverse insertion hanging groove.

[0020] By arranging the vibrating body below or in front of the transversely embedded hanging groove, the influence of the transversely embedded hanging groove can be suppressed, and the discomfort caused to the seated occupant (seat occupant) can be suppressed.

[0021] Furthermore, in the above configuration, a vertical insertion groove extending in the seat vertical direction or the seat front-rear direction may be formed in the pad member, and the vibrator may be arranged on the inner side of the vertical insertion groove in the seat width direction.

[0022] By arranging the vibrating body on the inner side of the vertically embedded hanging groove, the influence of the vertically embedded hanging groove can be suppressed, and the discomfort caused to the seated person can be suppressed.

[0023] Furthermore, in the above configuration, the pad member may have a seating surface formed with a housing recess for housing the vibrator, and a surface opposite to the seating surface may have a protrusion formed at a position corresponding to the housing recess.

[0024] By forming the convex portion on the surface opposite to the seating surface, it is possible to suppress a decrease in the rigidity of the pad member due to the storage concave portion and to facilitate positioning with respect to the pressure receiving member.

[0025] Furthermore, in the above-mentioned structure, a plurality of the vibrating bodies may be provided in the pad member, and a connecting portion for connecting the convex portions formed corresponding to the plurality of the vibrating bodies may be provided in the pad member.

[0026] By providing the connecting portion connecting the convex portions, it is possible to further suppress a decrease in the rigidity of the pad member due to the storage concave portion.

[0027] Furthermore, the structure may include a blower that blows air toward the occupant, and the vibrator may be arranged at a position avoiding an opening of the blower, a duct of the blower, or a mounting member of the blower.

[0028] By arranging the vibrator at a position away from the opening of the blower or the like, it is possible to suppress the influence on the air sent out from the blower.

[0029] Moreover, in the structure, the vehicle seat may include: a seat back supporting the back of the occupant; a seat cushion supporting the buttocks of the occupant; a headrest supporting the head of the occupant; and a skin covering the cushion component, and the frame may include: a seat back frame constituting the skeleton of the seat back; and a seat cushion frame constituting the skeleton of the seat cushion.

[0030] Effects of the Invention

[0031] According to the vehicle seat of the present invention constructed as described above, a part of the vibrator is arranged at a position that does not overlap with the pressure-receiving member when viewed from the front or from above, so when the occupant is seated, the vibrator does not interfere when the occupant sinks into the cushion member. Therefore, it is possible to provide a vehicle seat in which the vibrator is arranged at an appropriate position.

[0032] By arranging the vibrator outside the movable range of the pressure-receiving member, the vibrator does not interfere with the pressure-receiving member, and an increase in discomfort can be suppressed.

[0033] By arranging the vibrator so as to overlap with the opening, it is possible to suppress the discomfort caused to the seated person.

[0034] Furthermore, by arranging the vibrating body at a position overlapping with the through hole in the seat width direction, deformation of the pad member caused by the vibrating body can be absorbed.

[0035] Furthermore, by arranging the vibrating body below or in front of the transversely-embedded hanging groove, the influence of the transversely-embedded hanging groove can be suppressed, and the discomfort caused to the seated occupant (seat occupant) can be suppressed.

[0036] Furthermore, by arranging the vibrating body on the inner side of the vertically embedded hanging groove, the influence of the vertically embedded hanging groove can be suppressed, and the discomfort caused to the seated person can be suppressed.

[0037] Furthermore, by forming the convex portion on the surface on the opposite side to the seat surface, it is possible to suppress a decrease in the rigidity of the pad member due to the storage concave portion and to facilitate positioning with respect to the pressure receiving member.

[0038] Furthermore, by providing the connecting portion that connects the convex portions, it is possible to further suppress a decrease in the rigidity of the pad member due to the storage concave portion.

[0039] By arranging the vibrator at a position away from the opening of the blower or the like, it is possible to suppress the influence on the air sent out from the blower. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the actuator (not shown) provided in the rail device 4 can be driven to adjust the front-rear position of the seat body Sh.

[0183] <Headrest frame 30>

[0184] As described above, the headrest frame 30 is a member constituting the framework of the headrest 3. The headrest frame 30 is formed in an inverted U shape in front view, and can be attached to the upper end of the seat back 1 by inserting the headrest pillar 31 extending downward into the headrest bracket 14.

[0185] <Pad member P>

[0191] <Back pad 40>

[0192] like Figure 5 As shown, a first transverse hanging groove 41 extending in the seat width direction and a first longitudinal hanging groove 42 extending in the up-down direction are formed in the back cushion 40. The first transverse hanging groove 41 is equivalent to the transverse hanging groove of the present invention, and the first longitudinal hanging groove 42 is equivalent to the longitudinal hanging groove of the present invention.

[0193] The first horizontal insertion hanging groove 41 is connected to the upper end of the first vertical insertion hanging groove 42. The first vertical insertion hanging groove 42 is arranged between the main body portion 1a and the bank portion 1b of the seat back 1.

[0194] <Pad through hole 43>

[0195] A pad through hole 43 is formed along the first vertical insertion hanging groove 42 in a portion of the first vertical insertion hanging groove 42. The pad through hole 43 facilitates deformation of the back pad 40. Furthermore, the pad through hole 43 can absorb deformation of the back pad 40 caused by the vibrating body 60 described later.

[0196] Furthermore, when the vehicle seat S is provided with a blower 35 for sending out air, a duct through-hole 38 for inserting the duct 36 may be formed in the back cushion 40 .

[0197] <Storage recess 44>

[0198] like Figure 6 and Fig. 9 As shown, a receiving recess 44 for receiving the vibrating body 60 on the back side is formed on the seating surface 40a of the back pad 40. By inserting the vibrating body 60 into the receiving recess 44, the vibrating body 60 can be mounted.

[0199] After the vibrator 60 is inserted into the housing recess 44, the plate 45 is placed on the vibrator 60 to seal the housing recess 44. The plate 45 is fixed by a fixing tape 46.

[0200] like Figure 7 and Fig. 9 As shown, a harness hole 47 is formed on the bottom surface of the storage recess 44 , and the harness 65 extending from the vibrator 60 is passed through, so that the harness 65 can be introduced into the back surface 40 b of the back pad 40 .

[0201] <Vibrating body 60>

[0202] The vibrator 60 is a device for applying vibration to the seated occupant. In this embodiment, two vibrators 60 are arranged in the back pad 40. Two vibrators 60 are also arranged on the cushion pad side (hereinafter referred to as the vibrators 61 on the cushion pad side). The vibrators 60 on the back side and the vibrators 61 on the cushion pad side have the same mechanism.

[0203] An eccentric motor is used for the vibrating body 60. The vibrating body 60 is not limited to the eccentric motor, and a linear vibration actuator or a piezoelectric element may also be used. A wiring harness 65 extends from the vibrating body 60 and is connected to an electronic control unit (ECU) mounted in the vehicle. The ECU can control the intensity of vibration of the vibrating body 60 or the timing of vibration.

[0204] <Cushion pad 50>

[0205] like Figure 6 As shown, a second transverse hanging groove 51 extending in the seat width direction and a second longitudinal hanging groove 52 extending in the front-rear direction are formed in the cushion pad 50. The second transverse hanging groove 51 is equivalent to the transverse hanging groove of the present invention, and the second longitudinal hanging groove 52 is equivalent to the longitudinal hanging groove of the present invention.

[0206] The second longitudinal insertion hanging groove 52 is disposed between the main body portion 2a and the bank portions 2b provided on the left and right of the seat cushion 2. The second transverse insertion hanging groove is provided so as to connect two second longitudinal insertion hanging grooves 52.

[0207] The seating surface 50a of the cushion pad 50 is provided with a receiving recess 54 for receiving the vibrating body 61 on the cushion pad side. The vibrating body 61 can be installed by inserting the vibrating body 61 into the receiving recess 54. Figure 8 and Fig. 10A As shown, a harness hole 57 is formed on the bottom surface of the storage recess 54 , and the harness 65 extending from the vibrator 61 is passed through, so that the harness 65 can be introduced into the bottom surface 50 b of the cushion pad 50 .

[0208] After the vibrator 61 is inserted into the storage recess 54, the plate 55 is placed on the vibrator 61 to seal the storage recess 44. The plate 55 is fixed by the fixing tape 56. Figure 8 and Fig. 10AAs shown, a harness hole 57 is formed on the bottom surface of the storage recess 54 , and the harness 65 extending from the vibrator 61 is passed through, so that the harness 65 can be introduced into the bottom surface 50 b of the cushion pad 50 .

[0209] in addition, Fig. 10A In the cushion pad 50 shown in the figure, a harness hole 57 is formed on the bottom surface of the storage recess 54, but the position of the harness hole 57 is not limited thereto and may also be Fig. 10B As shown in the figure, the harness hole 57' is formed in the side wall and passes through the second horizontal hanging groove 51, thereby forming the harness hole 57' extending from the bottom of the second horizontal hanging groove 51 to the bottom surface 50b. In addition, the harness hole 57' can also use the hanging hole formed in the second horizontal hanging groove 51.

[0210] <Positions of Vibrating Bodies 60 and 61>

[0211] Hereinafter, the arrangement of the vibrating body 60 of the back pad 40 and the vibrating body 61 of the cushion pad 50 will be described with reference to the drawings.

[0212] Conventionally, in order to notify the occupant, a vibrator is disposed on the seat back or the seat cushion of the vehicle seat, but sufficient consideration has not been given to arranging the vibrator at an appropriate position.

[0213] In the vehicle seat S of this embodiment, two vibrating bodies 60 for generating vibrations are provided in the back pad 40. Figure 3 As shown, the two vibrators 60 are arranged at positions where at least a portion thereof does not overlap with the pressure receiving member 15 when the vehicle seat S is viewed from the front.

[0214] Specifically, the two vibrators 60 are arranged at positions overlapping the opening 15 c located on the side of the plate-shaped member 152 of the pressure-receiving member 15 and above the first side portion 153 in a front view.

[0215] By configuring in this way, for example, when the occupant is seated or when the vehicle is involved in a frontal collision, the occupant sinks into the cushion 50, but at this time, the vibrating body 60 does not prevent the occupant from sinking. That is, when sinking, the occupant presses the vibrating body 60 backward, but the movement of the vibrating body 60 is suppressed from being hindered by the pressure receiving member 15, so the occupant's sinking is not prevented. By configuring the vibrating body 60 in consideration of the position of the pressure receiving member 15, it is possible to provide a vehicle seat S in which the vibrating body 60 is arranged at an appropriate position.

[0216] Moreover, as described above, the pressure-bearing member 15 is configured to Figure 3The vibrating body 60 moves within the movable range R (prescribed range) shown in FIG. 1 , but the vibrating body 60 is arranged so as to be located outside the movable range R. Therefore, even if the pressure-receiving member 15 moves, the vibrating body 60 does not interfere with the pressure-receiving member 15. By configuring in this way, it is possible to suppress an increase in discomfort caused by the movement of the pressure-receiving member 15.

[0217] Moreover, if Figure 5 As shown in FIG. 1 , the vibrating body 60 is arranged at a position overlapping with the pad through hole 43 formed in the cushion pad 50 in the seat width direction. In other words, the vibrating body 60 is arranged in a manner so as to be at substantially the same height position as the pad through hole 43 in the seat vertical direction. By arranging in this way, the deformation of the back pad 40 caused by the vibrating body 60 can be absorbed by the pad through hole 43.

[0218] Moreover, if Figure 5 As shown in FIG. 1 , the vibrator 60 is arranged below the first horizontal insertion hanging groove 41 extending in the seat width direction. Furthermore, the vibrator 60 is arranged inside the first vertical insertion hanging groove 42 extending in the seat vertical direction in the seat width direction. In other words, the vibrator 60 is arranged to be sandwiched between the two first vertical insertion hanging grooves 42.

[0219] By arranging the vibrating body 60 in this manner, for example, the influence of the first transverse fitting hanging groove 41 and the first longitudinal fitting hanging groove 42 can be suppressed, and the discomfort caused to the seated person can be suppressed.

[0220] Furthermore, when the vehicle seat S is provided with a blower 35 and configured to send air from the seat back 1, there may be a case where Figure 5 As shown, the duct 36 is disposed on the upper portion of the seat back 1. In this case, the vibrator 60 can be disposed at a position avoiding the duct 36 provided on the cushion pad 50. By being disposed at a position avoiding the duct 36 extending from the blower 35, the influence on the air sent from the blower 35 can be suppressed.

[0221] The vibrating body 60 may be arranged not only away from the duct 36 but also away from the opening of the blower 35 or the blower mounting portion 37 where the blower 35 is mounted (see FIG. Fig.16A )’s location.

[0222] <Protrusion 48>

[0223] Moreover, it is also possible to Fig.11 and Fig.12 As shown, a convex portion 48 is formed at a position corresponding to the storage recess 44' on the back side 40Ab of the back pad 40A. By providing the convex portion 48, the rigidity reduction caused by the storage recess 44 can be suppressed, and the position of the vibrator 60 can be grasped even when viewed from the back side, so that the positioning of the pressure-receiving member 15 during assembly can be facilitated.

[0224] Moreover, it is also possible to Fig.12 As shown in FIG. 1 , a rib 49 (connecting portion) is provided to connect two convex portions 48 provided on the back surface 40Ab of the back pad 40A. By providing the rib 49, a decrease in rigidity due to the storage recess 44 can be further suppressed.

[0225] You can also Fig.11 As shown in FIG. 1 , a convex portion 58 is formed on the bottom surface 50Ab of the cushion pad 50A at a position corresponding to the housing concave portion 54 ′. In addition, a reinforcing rib (not shown) connecting the convex portion 58 may be formed.

[0226] Next, refer to Figure 3 , while explaining the positional relationship between the seat back frame 10 and the vibrating body 60. As described above, a pair of headrest brackets 14 are provided on the upper portion of the upper frame 12 of the seat back frame 10, and the headrest 3 is supported by holding the headrest pillow column 31. The vibrating body 60 provided on the seat back 1 can be like Figure 3 As shown in the figure, it is arranged outside the pair of headrest pillars 31 in the seat width direction (left-right direction). By arranging it in this way, it is possible to suppress the discomfort caused to the seated person.

[0227] As described above, the upper ends of the back frames 11, 11 and the lower ends of the upper frames 12 are connected by welding at the overlapped portion 17. The vibrating body 60 of the seat back 1 can be arranged at a position overlapping the overlapped portion 17 in the seat width direction. In other words, the vibrating body 60 can be arranged at substantially the same height as the overlapped portion 17.

[0228] Furthermore, the vibrating body 60 may be arranged at a position overlapping with the welded portion 18 in the overlapping portion 17 in the seat width direction.

[0229] The overlapping portion 17 and the welded portion 18 have high frame rigidity, and therefore, by arranging the vibrator 60 to overlap the overlapping portion 17 or the welded portion 18 in the seat width direction, the vibration of the vibrator 60 is easily transmitted to the seated person.

[0230] Furthermore, the upper end portion 15a of the pressure receiving member 15 is mounted using the upper mounting portion 16a of the connecting frame 16. The vibrating body 60 may be arranged so as to be located further inward than the upper mounting portion 16a in the seat width direction. In other words, the vibrating body 60 may be arranged so as to be sandwiched between the two upper mounting portions 16a in the seat width direction. By arranging in this way, for example, the influence on the pressure receiving member 15 can be suppressed.

[0231] Furthermore, the vibrating body 60 may be arranged inside the seat width direction relative to the outer end of the first side portion 153 extending outward from the plate-shaped member 152 of the pressure receiving member 15 (hereinafter referred to as the outer end of the pressure receiving member 15 ).

[0232] By arranging the vibrating body 60 on the inner side than the outer end of the pressure receiving member 15 , for example, the influence on the pressure receiving member 15 can be suppressed.

[0233] As described above, the actuator 33 is mounted on the lower end of the back side frame 11 of the seat back frame 10 via the actuator mounting portion 34 . The vibrating body 60 of the seat back 1 may be arranged above the actuator mounting portion 34 .

[0234] By configuring in this way, for example, the influence of the vibration of the actuator 33 can be suppressed.

[0235] Furthermore, the vibrating body 60 can be arranged within the left-right width of the front surface portion 13a of the bottom frame 13. In other words, the vibrating body 60 can be arranged inside the left and right ends of the front surface portion 13a of the bottom frame 13 in the seat width direction. By arranging the vibrating body 60 in this way, the influence of the pressure receiving member 15 can be suppressed.

[0236] Furthermore, the vibrating body 60 may be disposed below the upper frame 12. By disposing the vibrating body 60 at the lower part, it is possible to suppress the discomfort caused to the seated person.

[0237] Next, use Figure 4 and Figure 6 The arrangement of the vibrating body 61 arranged on the cushion pad 50 will be described.

[0238] In the vehicle seat S of this embodiment, two vibrating bodies 61 for generating vibration are provided in the cushion pad 50. Figure 4 As shown, the two vibrators 61 are arranged at positions where at least a portion does not overlap with the pressure receiving member 25 in a plan view of the vehicle seat S. That is, the vibrators 61 are arranged so as to overlap with the opening 25b formed in the pressure receiving member 25 in a plan view.

[0239] By arranging the vibrator 61 in this way, for example, when the occupant sits, the occupant is not hindered from sinking in. That is, since the opening 25b is present below the vibrator 61, the vibrator 61 is pushed and moved by the occupant sinking in, but the movement is suppressed from being hindered by the pressure receiving member 25. By arranging the vibrator 61 in this way, it is possible to provide a vehicle seat S in which the vibrator 61 is arranged at an appropriate position.

[0240] Moreover, if Figure 6 As shown, the vibrator 61 is arranged to be located in front of the second horizontal insertion hanging groove 51 extending in the seat width direction. In addition, the vibrator 61 is arranged inward of the second vertical insertion hanging groove 52 extending in the seat front-rear direction in the seat width direction. In other words, the vibrator 61 is arranged to be sandwiched between the two second vertical insertion hanging grooves 52.

[0241] By disposing the vibrating body 61 in this manner, for example, the influence of the second transverse insertion hanging groove 51 and the second longitudinal insertion hanging groove 52 can be suppressed, and the discomfort caused to the seated person can be suppressed.

[0242] Furthermore, when a pad through hole extending in the front-rear direction is formed in the cushion pad 50 of the present embodiment but not formed therein, the vibrating body 61 can be arranged at a position overlapping the pad through hole in the seat width direction. The pad through hole can absorb deformation of the cushion pad 50 caused by the vibrating body 61.

[0243] Moreover, if Figure 4 As shown, the vibrator 61 may be arranged further rearward than the base frame 24 of the seat cushion frame 20. Furthermore, the vibrator 61 may be arranged further rearward than the fixing portion 24a fixing the base frame 24 to the cushion side frame 21. Furthermore, the vibrator 61 may be arranged further rearward than the front side connecting frame 22.

[0244] By arranging the vibrating body 61 on the cushion pad 50 in this manner, for example, it is possible to suppress a seated person from feeling uncomfortable.

[0245] Furthermore, as described above, the seat switch unit 26 is provided in the cushion side frame 21 disposed on the right side of the seat cushion frame 20 .

[0246] The vibrating body 61 may be disposed at a position overlapping the seat switch unit 26 in the seat width direction. In other words, the vibrating body 61 may be disposed at substantially the same position as the seat switch unit 26 in the seat front-rear direction.

[0247] Since the frame rigidity is increased by providing the seat switch unit 26 , the vibration generated by the vibrating body 61 is easily transmitted to the seated person.

[0248] Moreover, if Fig. 9 As shown in FIG. 1 , the pressure receiving member 25 has an inclined portion 25a that is inclined downward toward the rear. The vibrator 61 can be arranged so as to overlap with the inclined portion 25a of the pressure receiving member 25 when viewed from above. That is, the vibrator 61 can be arranged above the inclined portion 25a. By arranging the vibrator 61 in this way, for example, it is possible to suppress discomfort caused to the seated person.

[0249] <Another example of a method for fixing a vibrating body>

[0250] Fig. 10A In the method for fixing the vibrator 61 shown in FIG. 1 , a receiving recess 54 is formed on the seat surface 50a of the cushion pad 50, and the vibrator 61 is inserted and fixed by covering it with a plate material 55. However, the method for fixing the vibrator 61 is not limited to this. FIG. 13A to FIG. 13C Another example of a method of fixing the vibrators 60 and 61 will be described.

[0251] You can also Fig.13A As shown, the vibrating body 61 covered with the plate material 55 is housed in the housing recess 54A of the cushion pad 50A and fixed with the fixing tape 56 .

[0252] Moreover, it is also possible to Fig. 13B As shown, the vibrating body 61 covered by the waterproof cover 63 is integrally formed with the cushion pad 50B, thereby fixing the vibrating body 61.

[0253] Moreover, it is also possible to Fig. 13C As shown, the cushion pad 50C is integrally formed with the openable and closable cover 64, and the vibrator 61 is received and fixed in the receiving recess 54C. In addition, the cushion pad 50C may be formed so that the hardness of the cover 64 is higher than that of other parts.

[0254] <About the process of appropriately imparting vibration>

[0255] It is required to appropriately impart the vibration generated by the vibrating body to a seated person (eg, a seated passenger). By appropriately imparting the vibration, the seated person's ability to recognize the vibration is improved.

[0256] The timing and amount of operation of the vibrating bodies 60 and 61 of this embodiment are controlled by the ECU mounted on the vehicle. Functional parts other than the vibrating body 60 (other functional parts) are also controlled by the ECU. Hereinafter, such a system is referred to as a vibration system.

[0257] In order to appropriately impart vibration, the vibration system may include a limiting component that limits the operation of other functional parts when, for example, the operation of the vibration body 60 is required and / or when the operation of the vibration body 60 is in progress.

[0258] The so-called other functional parts refer to devices located around the seated person, especially devices provided on the seat, such as air conditioning devices such as a blower 35, sound generating devices such as a speaker, and massage devices provided on the vehicle seat S. The other functional parts may also be a seat shape changing device that changes the shape of the vehicle seat S, a seat position changing device that changes the position of the vehicle seat S, and a window opening and closing device that opens and closes a window such as a vehicle window.

[0259] By restricting the operation of other functional parts, the seated occupant can appropriately recognize the vibrations generated by the vibrating bodies 60 and 61 .

[0260] Furthermore, the so-called restriction of the operation of other functional parts may be, for example, prohibiting the operation of other functional parts, or reducing the operation speed, operation amount or number of operations of other functional parts compared to when the vibrators 60 and 61 are not operating.

[0261] Furthermore, the operation of other functional parts may be restricted for a specified time after the operation of the vibrating bodies 60 and 61 is completed. That is, even after the operation of the vibrating bodies 60 and 61 is completed, the state of restricting the operation of other functional parts continues for a specified time (e.g., a short time such as five seconds or ten seconds).

[0262] It is possible to suppress the repetition of the restricted state and the operating state of other functional parts, thereby suppressing the discomfort of the seated person.

[0263] Furthermore, the vibration system may also include an operation amount changing component, which, when other functional parts are operating, makes the operation amount of the vibrators 60 and 61 larger than when other functional parts are not operating. That is, when other functional parts are operating, the vibrators 60 and 61 increase the vibration or extend the vibration time, thereby increasing the amount transmitted to the seated person.

[0264] This allows the seated person to appropriately recognize the vibrations generated by the vibrating bodies 60 and 61 .

[0265] When the operation amount of the vibrators 60 and 61 is increased, the vibrators 60 and 61 may be operated for a predetermined time (e.g., a short time such as five seconds or ten seconds) even after the operation of other functional parts has ended. By continuing the operation, it is possible to suppress the repeated changes in the operation state of the vibrators 60 and 61, thereby suppressing the discomfort of the seated person.

[0266] Next, refer to FIG. 14A to FIG. 23B In the drawings, the positions where the vibrating body 60 can be arranged are indicated by dotted lines. The number of vibrating bodies 60 to be arranged is not limited to two, but may be one, or may be three or more.

[0267] Figures 14A to 18B The diagram shows the positional relationship between the vibrating body 60 disposed on the back pad 40 and the seat back frames 10A to 10E.

[0268] in addition, Figures 14A to 18B In the seat back frames 10A to 10E' shown in the figure, the structure of the pressure receiving member 15A to 15E is different, and the structure of the back frame 11, the upper frame 12, and the bottom frame 13 is the same as that of the seat back frame 10A to 10E'. Figure 3 The seat back frame 10 shown is the same and thus is denoted by the same reference numerals, and detailed description thereof is omitted.

[0269] Fig.14A The illustrated pressure-receiving member 15A includes a wire member 151A and a plate-shaped member 152A, and the load of the occupant is received by both the wire member 151A and the plate-shaped member 152A.

[0270] The vibrating body 60 may also be Fig.14A The vibrating bodies 60A to 60Ab shown in FIG. 1 are arranged at positions overlapping with the openings of the wire members 151A when viewed from the front. Fig.14A The vibrating body 60Ac shown in FIG. 1 is disposed at the connection portion between the linear member 151A and the plate-shaped member 152A. The vibrating body 60 may also be configured as Fig.14A As shown in the vibrating body 60Ad, it is arranged at a position overlapping with the opening between the plate-shaped member 152A and the back frame 11 in a front view.

[0271] By arranging in this way, when the occupant sinks into the pad member, the vibrating body 60 does not get in the way.

[0272] Fig. 14B The pressure-receiving member 15A' of the seat back frame 10A' shown includes a wire member 151A' and a plate-shaped member 152A, and the load of the occupant is received by both the wire member 151A' and the plate-shaped member 152A. Fig. 14B The wire member 151A' is shown with Fig.14A Compared with the wire member 151A shown, the number of constituent wires is increased.

[0273] The vibrating body 60 may also be Fig. 14B As shown in the vibrating body 60Ad, it is arranged at a position overlapping with the wire member 151A' in front view.

[0274] Moreover, it can also be like Fig. 14B As shown in FIG. 6 , the vibrating body 60Ae is arranged at a position overlapping with the plate-shaped member 152A in a front view.

[0275] By arranging the vibrating body 60 at a position overlapping with the pressure receiving member 15A′ in front view in this manner, the vibrating body 60 can be firmly supported.

[0276] Fig.15A The pressure-bearing member 15B shown includes a wire member 151B and a plate-like member 152B. Figure 3 Compared with the pressure-bearing member 15 shown in the figure, the longitudinal length of the plate-like member 152B is shortened, and the wire member 151B supporting the plate-like member 152B is correspondingly lengthened. The longitudinally extending wire members 151B are connected by wire connecting members. In addition, the wire members 151B are provided with wire auxiliary members 155B extending in the seat width direction.

[0277] The vibrating body 60 may also be Fig.15A In the embodiment shown in FIG. 1 , the vibrator 60B and 60Ba are arranged in the opening of the wire member 151B in front view. In addition, the vibrator 60Bc can be arranged to overlap with the wire member 151B in front view. In addition, the vibrator 60Bd can be arranged to partially overlap with the wire connecting member.

[0278] Furthermore, the vibrator 60 may be disposed outside the first side portion 153B of the plate-shaped member 152 like the vibrator 60Be. The vibrator 60 may be disposed outside the second side portion 154B like the vibrator 60Bf.

[0347] <<Second embodiment>>

[0348] A second embodiment of the present invention will be described below.

[0349] <<Technical Field / Background Technology>>

[0350] The present invention relates to a vehicle seat, and in particular to a vehicle seat comprising a vibrating body.

[0351] In the past, there has been development of obstacle approach notification systems that notify seated passengers when obstacles or other vehicles approach the periphery of the vehicle. For example, external sensors installed in the front, back, left, and right sides of the vehicle monitor the presence of approaching objects in the periphery of the vehicle, and when an approaching object is detected, a notification signal including sound or light is output. In this way, the approach of obstacles or the like is notified to seated passengers to warn them and allow them to avoid danger, thereby achieving improved safety for seated passengers.

[0352] Moreover, International Publication No. 2019 / 044826 discloses a vibration control device, which utilizes a vibration unit built into a seat (driver's seat) of a vehicle as a notification component. Specifically, a vibration control component is disclosed, which can notify the approach of an obstacle and the direction of approach by vibrating a vibration unit arranged in the direction of approaching an obstacle.

[0353] By using a vibration unit as the notification member as in the technique described in Patent Document 1, the driver can be notified of the presence of an approaching object even in a situation where the driver has difficulty visually or auditorily recognizing the object, for example, in a situation where it is difficult for the driver to direct his or her line of sight toward the notification member.

[0354] <<Disclosure of the Invention>>

[0355] <<Problems to be solved by the invention>>

[0356] According to the technology described in International Publication No. 2019 / 044826, the effectiveness of the vibration unit can be seen as a notification component for notifying the approach and approach direction of an obstacle without relying on the vision or hearing of the seated person. However, in a seat with a movable mechanism that can change its position or posture, it is impossible to notify the approach direction of the obstacle corresponding to its position or posture. Therefore, for example, there is the following problem: when the seat is changed to a rearward rotation position relative to the direction of travel of the vehicle, the approach direction of the obstacle cannot be accurately notified.

[0357] The present invention is completed in view of the above-mentioned problems, and its purpose is to provide a seat for a vehicle, which includes a movable mechanism that can change the position or posture of the seat body and a vibrating body as a notification component, which can perform appropriate notification corresponding to the position and posture of the seat body.

[0358] <<Technical means to solve the problem>>

[0359] The problem is solved in the following manner, that is, according to the seat for a vehicle of the present invention, a seat for a vehicle includes: a seat body, which is arranged in a vehicle; a movable mechanism, which changes the position and posture of the seat body; a plurality of vibrators, which are arranged in the seat body; and a control device, which drives and controls the plurality of vibrators, wherein the plurality of vibrators are built into the seat body at positions different from each other in the front-to-back direction and the seat width direction, and the control device selects a vibration notification mode based on the position and posture of the seat body to drive and control the vibrators, and the vibration notification mode informs the occupant by causing at least one of the plurality of vibrators to vibrate in a specified order and with specified vibration parameters.

[0360] According to the above configuration, the control device selects one vibration notification mode from a plurality of vibration notification modes based on the position and posture of the seat body to control the vibrator. Therefore, the vehicle seat can perform appropriate notification according to its position and posture.

[0361] Furthermore, the movable mechanism may include a rotation mechanism for changing a rotation position of the seat body around a rotation axis in a vertical direction, and the control device may select the vibration notification mode based on the rotation position of the seat body.

[0362] According to the above configuration, the vehicle seat can be appropriately notified according to the rotation position thereof.

[0363] Moreover, the rotating mechanism can change the seat body between a first rotation position facing the front of the vehicle and a second rotation position facing the rear of the vehicle, and the control device selects a first vibration notification mode when the seat body is in the first rotation position, and selects a second vibration notification mode when the seat body is in the second rotation position, and the second vibration notification mode is a vibration notification mode that selects the vibration body located on the opposite side with the rotation axis as the center relative to the vibration body that vibrates when the first vibration notification mode is selected.

[0364] According to the structure, when the control device is in the rotation position facing the rear of the vehicle, it selects the vibration notification mode selected when it is in the rotation position facing the front of the vehicle and the vibration notification mode in which the vibrating body located on the opposite side of the rotation axis vibrates. Therefore, when the vehicle seat is in the rotation position facing the rear of the vehicle, appropriate notification can be made.

[0365] Moreover, the rotating mechanism can change the seat body between a first rotation position facing the front of the vehicle and a third rotation position facing a direction rotated 90 degrees from the front of the vehicle toward one of the rotation directions, and the control device selects a first vibration notification mode when the seat body is located at the first rotation position, and selects a third vibration notification mode when the seat body is located at the third rotation position, and the third vibration notification mode is the vibration notification mode that selects to vibrate the vibrating body that is located on the side of the direction rotated 90 degrees toward another rotation direction with the rotation axis as the center relative to the vibrating body that vibrates when the first vibration notification mode is selected.

[0366] According to the above structure, when the control device is in a rotation position rotated 90 degrees from the front of the vehicle in one rotation direction, it selects the vibration notification mode selected when it is in a rotation position toward the front of the vehicle and the vibration notification mode in which the vibrator located on the side of the direction rotated 90 degrees in the other rotation direction with the rotation axis as the center vibrates. Therefore, when the vehicle seat is in a rotation position toward the side of the vehicle, appropriate notification can be performed.

[0367] Furthermore, the movable mechanism may include a slide mechanism that changes the front-rear position of the seat body along a slide rail extending in the front-rear direction, and the control device may select the vibration notification mode based on the front-rear position of the seat body.

[0368] According to the above configuration, the vehicle seat can provide appropriate notification according to the position in the front-rear direction of the vehicle seat.

[0369] Moreover, the seat body may have a seat cushion and a seat back, and the movable mechanism may have a leaning mechanism, which changes the posture of the seat body between an upright posture in which the seat back is upright relative to the seat cushion and a tilted posture in which the seat back is tilted backward at a specified tilting angle relative to the seat cushion, and the control device selects the vibration notification mode based on the tilting angle.

[0370] According to the above configuration, the control device selects the vibration notification mode based on the tilting angle of the seat back relative to the seat cushion, so that the vehicle seat can perform appropriate notification according to the posture.

[0371] Moreover, the seat body may have left and right armrests, and the vibrator may have arm vibrators respectively arranged on the left and right armrests. The control device selects the vibration notification mode for vibrating at least one of the left and right arm vibrators in a prescribed order and with prescribed vibration parameters based on the position and posture of the seat body.

[0372] According to the above configuration, the vehicle seat can provide appropriate notification according to the position and posture of the vehicle seat by vibrating the arm vibrator provided on the armrest.

[0373] Moreover, the seat body may have a leg support, and the vibrator may have a plurality of foot vibrators arranged on the leg support. The control device may select the vibration notification mode for vibrating at least one of the plurality of foot vibrators in a prescribed order and with prescribed vibration parameters based on the position and posture of the seat body.

[0374] According to the above configuration, the vehicle seat can provide appropriate notification according to the position and posture of the vehicle seat by vibrating the leg vibrator provided on the leg support.

[0375] Furthermore, the seat body may include a headrest having a plurality of sound output devices built therein, and the control device outputs a sound signal from the sound output device located in the same direction as the one vibrator when viewed from the seated person, based on the position and posture of the seat body. According to the above configuration, the vehicle seat can provide appropriate notification corresponding to the position and posture of the vehicle seat by vibrating the head vibrator provided in the headrest.

[0376] Furthermore, the seat body may include: a seat frame forming a framework of the seat body; a cushion material placed on the seat frame; and a surface material covering the cushion material.

[0377] According to the above configuration, it is possible to provide a vehicle seat that can provide appropriate notification according to the position and posture.

[0378] <<Effects of the Invention>>

[0379] According to the vehicle seat of the present invention, appropriate notification can be performed according to the position and posture.

[0380] Furthermore, appropriate notification can be performed according to the rotation position of the vehicle seat.

[0381] Furthermore, when the vehicle seat is in the rotation position facing the rear of the vehicle, appropriate notification can be made.

[0382] Furthermore, when the vehicle seat is in the rotation position facing the side of the vehicle, appropriate notification can be made.

[0383] Furthermore, the vehicle seat can provide appropriate notification according to the position of the vehicle seat in the front-rear direction.

[0384] Furthermore, the vehicle seat can provide appropriate notification according to the posture.

[0385] <<Specific implementation method>>

[0386] Hereinafter, the structure of the vehicle seat of the first embodiment of the second embodiment of the present invention will be described with reference to the accompanying drawings. However, the embodiments described below are intended to facilitate the understanding of the present invention and do not limit the present invention. That is, the present invention may be changed and improved without departing from its main purpose, and the present invention certainly includes its equivalents.

[0387] Furthermore, in the following description, the materials, shapes, and sizes of seat components are merely specific examples and do not limit the present invention.

[0388] In addition, the following describes a structural example of a vehicle seat S20 mounted on a vehicle V20 as an example of a vehicle seat. However, the present invention is not limited to seats mounted on vehicles with wheels such as cars and trains that travel on the ground, and can also be applied to seats mounted on aircraft or ships that move on other than the ground.

[0389] Moreover, in the following description, the so-called "seat front-to-back direction" refers to the front-to-back direction of the vehicle seat S20, which is the direction consistent with the front-to-back direction observed from the seated person sitting on the vehicle seat S20. The so-called "vehicle front-to-back direction" refers to the direction consistent with the traveling direction when the vehicle is traveling. Moreover, the so-called "seat width direction" refers to the horizontal width direction of the vehicle seat S20, which is the direction consistent with the left-right direction observed from the seated person sitting on the vehicle seat S20. Moreover, the so-called "up-down direction" refers to the up-down direction of the vehicle seat S20, which is the direction consistent with the vertical direction when the vehicle V20 is traveling on a horizontal plane. Moreover, when it is simply referred to as "outside", it refers to the side close to the outside in the direction from the center of a single vehicle seat S20 toward the outside, and when it is referred to as "inside", it refers to the side close to the center in the direction from the outside of a single vehicle seat S20 toward the center.

[0390] <Overview of vehicle seat S20>

[0391] Fig.24 1 shows the interior of a vehicle V20 equipped with the vehicle seat S20 of the present invention. Fig.24 As shown, the vehicle V20 includes three rows of vehicle seats S20 along the vehicle front-rear direction. A vibrating body 220 (see FIG. 2 ) used as a notification member is built into each vehicle seat S20. Fig.25). Moreover, the vehicle seat S20 includes a movable mechanism that can change its position and posture in the vehicle cabin. The vehicle seat S20 of the present invention is used to select the vibration mode of the vibrator 220 based on the position and posture of the vehicle seat S20, thereby appropriately informing the occupant sitting in the vehicle seat S20.

[0411] <Regarding the functional structure of the vehicle seat S20>

[0412] Next, the functional structure of the vehicle seat S20 will be described.

The control device 230 is built into the vehicle seat S20 to be responsible for overall control of the vehicle seat S20.

[0414] The external sensor 240 is a sensor that detects the surrounding information of the vehicle V20, that is, the external conditions. In detail, the external sensor 240 may include a lidar that measures the scattered light of the omnidirectional irradiation light relative to the vehicle V20 to measure the distance from the vehicle V20 to the surrounding obstacles. In addition, the external sensor 240 may include a radar that detects other vehicles or obstacles around the vehicle V20 by irradiating electromagnetic waves and detecting reflected waves. The external sensor 240 may further include an optical sensor that captures the surrounding images of the vehicle V20.

[0415] Fig.28 The installation position of the external sensor 240 relative to the vehicle V20 is schematically shown. Fig. 27 and Fig.28 As shown, the external sensor 240 includes a right front sensor 240RF, a right rear sensor 240RR, a left front sensor 240LF, and a left rear sensor 240LR. However, the number and configuration of the sensors are not limited to Fig.28 For example, in Fig.28 In the example, additional sensors may be configured at the locations described by white circles.

[0416] The right front sensor 240RF is arranged in the right front of the vehicle V20 to detect the conditions in front of and to the right of the vehicle V20.

[0417] The right rear sensor 240RR is arranged at the right rear of the vehicle V20 to detect the conditions behind and to the right of the vehicle V20.

[0418] The left front sensor 240LF is arranged at the left front of the vehicle V20 to detect the conditions in front of and to the left of the vehicle V20.

[0419] The left rear sensor 240LR is arranged at the left rear of the vehicle V20 to detect the conditions behind and to the left of the vehicle V20.

[0420] The slide position sensor 241 is a sensor for detecting the position of the vehicle seat S20 in the front-rear direction of the vehicle V20. The slide position sensor 241 is an encoder provided on the output shaft of the motor, which is the driving source of the track device 204, but is not limited thereto. The slide position sensor 241 may be a position detection component of a radar type that transmits and receives microwaves, or a position detection component of a type that performs image recognition processing on a captured image obtained by a vehicle-mounted camera to obtain the position of the vehicle seat S20.

[0421] The rotation angle sensor 242 is a sensor that detects the rotation position of the vehicle seat S20 around the rotation axis B20 extending in the vertical direction. The rotation angle sensor 242 is a limit switch whose contacts are connected when the vehicle seat S20 rotates more than a certain angle, but is not limited to this. The rotation angle sensor 242 may also be an optical sensor including a light emitting diode and a photodiode, or a position detection component using a vehicle-mounted camera.

[0422] The reclining angle sensor 243 is a sensor for detecting the posture of the vehicle seat S20. More specifically, the reclining angle sensor 243 acquires the tilting angle of the seat back 202 relative to the seat cushion 201. The reclining angle sensor 243 is an encoder provided on the output shaft of the motor of the reclining device 206, but is not limited thereto. The reclining angle sensor 243 may also be a posture detection component for detecting the posture of the vehicle seat S20 using a captured image acquired by a vehicle-mounted camera.

[0423] The vibrating body 220 is an eccentric motor including a motor and an eccentric weight fixed to the output shaft of the motor, but is not limited thereto. The vibrating body 220 may also be a linear resonance actuator having a magnet and a winding as a main structure. The vibrating body 220 stimulates the seated person by vibration, thereby functioning as a notification component. The vibration mode of the vibrating body 220 will be described later.

[0424] The vibrating body 220 includes a seat cushion vibrating body 221 built into the seat cushion 201 and a seat back vibrating body 222 built into the seat back 202 , but the present invention is not limited thereto. The vibrating body 220 may be built into the headrest 203 .

[0425] The seat cushion vibrating bodies 221 are arranged to be separated from each other in the seat width direction. Specifically, the seat cushion vibrating body 221 includes a right vibrating body 221R arranged in the right direction of the seat and a left vibrating body 221L arranged in the left direction of the seat.

[0426] The seat back vibrating bodies 222 are arranged to be separated from each other in the seat front-rear direction and the seat width direction. Specifically, the seat back vibrating body 222 includes an upper right vibrating body 222RU arranged at the upper right of the seat, a lower right vibrating body 222RD arranged at the lower right of the seat, an upper left vibrating body 222LU arranged at the upper left of the seat, and a lower left vibrating body 222LD arranged at the lower left of the seat.

[0427] The speaker 244 is provided on the headrest 203. In other words, the headrest 203 has a plurality of speakers 244, and the plurality of speakers 244 at least include a right speaker 244R disposed on the right side of the seat and a left speaker 244L disposed on the left side of the seat. The speaker 244 can emit a warning sound or a message including sound in addition to music. The speaker 244 is equivalent to a sound output device.

[0428] The control device 230 is an electronic control unit (ECU) installed in the vehicle seat S20. The control device 230 includes a processor for executing a program, a non-volatile storage medium, and a volatile storage medium. In addition, the processor functions as an acquisition unit 231, a state recognition unit 232, a vibration mode determination unit 233, and a vibration control unit 234 by executing the program stored in the non-volatile storage medium.

[0429] The acquisition unit 231 has a communication interface, and acquires the external signal output by the external sensor 240 and the signals related to the position and posture of the vehicle seat S20 output by the slide position sensor 241, the rotation angle sensor 242, and the reclining angle sensor 243. In addition, the acquisition unit 231 can acquire information related to the driving state of the vehicle V20 (driving speed, etc.) through the communication interface.

[0430] The situation recognition unit 232 detects obstacles around the vehicle V20 based on the external signal output by the external sensor 240. Moreover, the situation recognition unit 232 determines the type of the object (such as a pedestrian or other vehicle) according to the characteristics of the detected obstacle. Next, the situation recognition unit 232 calculates the collision probability between the detected object and the vehicle V20. The calculation of the collision probability is performed by considering the approaching speed of the object toward the vehicle V20. The situation recognition unit 232 can also determine the collision form (frontal collision, rear collision, side collision) between the vehicle V20 and the object and calculate the collision probability during a specific collision (such as a side collision). The situation recognition unit 232 compares the calculated collision probability with a predetermined threshold value to determine the presence of an approaching object, and outputs the determination result and the approaching direction of the approaching object as the situation recognition result to the vibration mode determination unit 233.

[0431] Furthermore, the situation recognition unit 232 calculates the departure probability of another vehicle (preceding vehicle) detected at a position in front of the vehicle V20 while the vehicle V20 is stopped. The departure probability is calculated by taking into account the travel speed of the vehicle V20 and the speed at which the preceding vehicle leaves. The situation recognition unit 232 compares the calculated departure probability with a predetermined threshold value to determine the departure fact of the preceding vehicle, and outputs the determination result as a situation recognition result to the vibration mode determination unit 233.

[0432] The vibration mode determination unit 233 determines the vibration mode of the vibrating body 220 based on the situation recognition result of the situation recognition unit 232 and the position and posture of the vehicle seat S20. More specifically, the vibration mode determination unit 233 selects a vibration mode from a plurality of vibration modes prepared in advance when it is necessary to notify the seated person through the vibrating body 220, thereby determining the vibration mode. The vibration mode is equivalent to the vibration notification mode.

[0433] The vibration pattern is information that specifies the order and vibration parameters of at least one of the plurality of vibration bodies 220 built into the seat cushion 201 and the seat back 202 in which the vibration is performed. Here, the vibration parameters include information related to the vibration intensity (vibration frequency) and vibration time of the vibration body 220. Furthermore, the vibration parameters may also include information related to the vibration period or vibration rhythm when the vibration body 220 repeatedly vibrates. The vibration pattern is stored in a vibration pattern table stored in the non-volatile memory of the control device 230.

[0434] For the method of selecting the vibration mode by the vibration mode determination unit 233, refer to Figure 29 to Figure 3 6 will be discussed later.

[0435] The vibration control unit 234 controls the vibration of the vibrating body 220 based on the vibration mode determined by the vibration mode determination unit 233. In other words, the vibration control unit 234 controls so that at least one vibrating body 220 among the plurality of seat cushion vibrating bodies 221 and the plurality of seat back vibrating bodies 222 vibrates based on the determined vibration mode.

[0436] <About the flow of vibration notification processing>

[0437] Next, the flow of the vibration notification process performed by the control device 230 is described. The vibration notification process is performed in accordance with the driving state of the vehicle V20 and the external conditions to urge the passengers to pay attention. Specifically, the control device 230 can perform the notification process during stop, the notification process during driving, the notification process when starting, and the notification process when reversing in accordance with the driving state of the vehicle V20.

[0438] First, the stop notification process executed by the control device 230 when the vehicle V20 is stopped will be described. Fig.29 2 shows the flow of the stop notification process performed by the control device 230. First, the control device 230 determines whether the other vehicle (preceding vehicle) detected in front of the vehicle V20 has started (step S210). More specifically, the control device 230 determines whether the preceding vehicle has started based on the situation recognition result output by the situation recognition unit 232.

[0439] If it is determined that the preceding vehicle has not yet started (step S210 : No), the control device 230 is on standby.

[0440] On the other hand, if it is determined that the preceding vehicle has started (step S210: Yes), the control device 230 obtains a signal related to the state of the vehicle seat S20 (step S211). More specifically, the control device 230 obtains a signal related to the position and posture of the vehicle seat S20 from the slide position sensor 241, the rotation angle sensor 242, and the reclining angle sensor 243.

[0441] Next, the control device 230 determines whether the rotation position of the vehicle seat S20 is the forward rotation position (step S212). Specifically, the control device 230 compares the rotation angle signal output by the rotation angle sensor 242 with a predetermined value to determine whether the vehicle seat S20 is in the rotation position facing the front of the vehicle V20.

[0442] If it is determined that the rotation position of the vehicle seat S20 is facing forward (step S212: YES), the control device 230 controls the seat cushion vibrator 221 to vibrate (step S213). Specifically, the control device 230 selects a vibration mode for vibrating the seat cushion vibrator 221, thereby vibrating the seat cushion vibrator 221.

[0443] Fig. 30A The state in which the seat cushion vibrating body 221 is vibrating due to the stop notification processing performed by the control device 230 is shown. Fig. 30A As shown, when the vehicle seat S20 is in a rotation position facing the front of the vehicle V20, the control device 230 vibrates the seat cushion vibrator 221, thereby notifying the seated person that the preceding vehicle has departed. In other words, the control device 230 vibrates the vibrator 220 disposed at a position closer to the front side of the seat than the rotation axis B20 of the rotating device 205 of the vehicle seat S20. Here, the seat cushion vibrator 221 vibrates at a position closer to the front side of the seat than the body axis of the seated person. As a result, the seated person's consciousness can be directed toward the front of the seat, and the seated person can be urged to follow the preceding vehicle to depart for the vehicle V20.

[0444] On the other hand, if it is determined that the rotation position of the vehicle seat S20 is not forward (step S212: No), the control device 230 controls the seat back vibrating body 222 to vibrate (step S214). Specifically, the control device 230 selects a vibration mode for vibrating the seat back vibrating body 222, thereby vibrating the seat back vibrating body 222. In other words, when the vehicle seat S20 is in the rotation position facing the rear of the vehicle V20, the control device 230 selects a vibration mode for vibrating the vibrating body 220 located on the opposite side with respect to the vibrating body 220 vibrating when it is in the rotation position facing the front, with respect to the rotation axis B20 of the rotating device 205. Here, the so-called "vibrating body 220 located on the opposite side with respect to the rotation axis B20" is not limited to the vibrating body 220 located strictly in the opposite position with respect to the rotation axis B20 of the rotating device 205, but includes the vibrating body 220 located in the opposite direction with respect to the rotation axis B20 of the rotating device 205. The rotational position of the vehicle seat S20 toward the front of the vehicle V20 corresponds to the first rotational position, and the rotational position of the vehicle seat S20 toward the rear of the vehicle V20 corresponds to the second rotational position. Furthermore, the vibration mode selected when the vehicle seat S20 is in the rotational position toward the front of the vehicle V20 corresponds to the first vibration notification mode, and the vibration mode selected when the vehicle seat S20 is in the rotational position toward the rear of the vehicle V20 corresponds to the second vibration notification mode.

[0445] Fig. 30BThe vehicle seat S20 is shown in a state where the seat back vibrating body 222 is vibrating due to the stop notification processing performed by the control device 230. Fig. 30B As shown, when the vehicle seat S20 is in a rotation position facing the rear of the vehicle V20, the control device 230 vibrates the seat back vibrator 222, thereby notifying the seated person that the preceding vehicle has departed. In other words, the control device 230 vibrates the vibrator 220 disposed at a position closer to the rear side of the seat than the rotation axis B20 of the rotating device 205 of the vehicle seat S20. Here, the seat back vibrator 222 vibrates at a position closer to the rear side of the seat than the body axis of the seated person. As a result, the seated person's consciousness can be directed to the rear of the seat, and the seated person can be notified that the vehicle V20 will soon follow the preceding vehicle and depart toward the rear side of the seat.

[0446] When the vibration control of the vibrating body 220 in step S213 and step S214 is completed, the control device 230 completes the stop notification process. In addition, the control device 230 may also measure the time that the vehicle V20 is in the stop state from the departure of the preceding vehicle, and if the vehicle V20 is still in the stop state for more than a predetermined time, the seat cushion vibrating body 221 or the seat back vibrating body 222 is vibrated.

[0447] Next, a description will be given of the traveling notification process executed by the control device 230 when the vehicle V20 is traveling. Fig.31 2 shows the flow of the in-running notification process executed by the control device 230. Fig.31 As shown, the control device 230 first determines the presence and approach direction of an approaching object (e.g., another vehicle approaching from behind the target lane during the lane change of the vehicle V20) (step S220). More specifically, the control device 230 determines the presence and approach direction of an approaching object based on the situation recognition result output by the situation recognition unit 232.

[0448] If it is not determined that there is an approaching object (step S220 : No), the control device 230 is on standby.

[0449] On the other hand, if it is determined that there is an approaching object (step S220: Yes), the control device 230 obtains information related to the state of the vehicle seat S20 (step S221). More specifically, the control device 230 obtains signals related to the position and posture of the vehicle seat S20 from the slide position sensor 241, the rotation angle sensor 242, and the leaning angle sensor 243. In addition, in the following description, the approaching direction of the approaching object is assumed to be the right rear of the vehicle V20.

[0450] Next, the control device 230 determines whether the rotational position of the vehicle seat S20 is the forward rotational position (step S222). Specifically, the control device 230 compares the rotational angle signal output by the rotational angle sensor 242 with a predetermined value to determine whether the vehicle seat S20 is facing forward of the vehicle V20.

[0451] If it is determined that the rotation position of the vehicle seat S20 is forward (step S222: Yes), the control device 230 controls so that the seat back vibrator 222 and the seat cushion vibrator 221 vibrate in this order (step S223). Specifically, the control device 230 selects a vibration mode in which the seat back vibrator 222 and the seat cushion vibrator 221 vibrate in this order. As a result, the seat back vibrator 222 and the seat cushion vibrator 221 vibrate in this order.

[0452] Fig.32A The control device 230 performs the driving notification process and the seat back vibrator 222 and the seat cushion vibrator 221 vibrate in this order. More specifically, the following state is shown: when the vehicle V20 changes the driving lane to the lane further to the right than the current driving lane, another vehicle (approaching object) approaching from the right rear is detected. Fig.32A As shown, when the vehicle seat S20 is in the rotation position facing the front of the vehicle V20, the control device 230 first vibrates the upper right vibrator 222RU of the seat back vibrator 222 located on the rear side of the seat. Next, the control device 230 vibrates the lower right vibrator 222RD. Finally, the control device 230 vibrates the right vibrator 221R of the seat cushion vibrator 221 located on the front side of the seat, thereby notifying that another vehicle is approaching from the right rear of the vehicle V20. In other words, the control device 230 vibrates the vibrator 220 in such a manner that the vibration position is shifted from the vibrator 220 located on the right rear side of the rotation axis B20 of the vehicle seat S20 in the seat front-rear direction toward the vibrator 220 located on the right front side. As a result, the awareness of the seated person can be gradually shifted from the right rear side of the seat to the right front side of the seat, and the seated person can be urged to pay attention to another vehicle approaching from the right rear side of the vehicle V20.

[0453] On the other hand, if it is determined that the rotation position of the vehicle seat S20 is not forward (step S222: No), the control device 230 controls so that the seat cushion vibrator 221 and the seat back vibrator 222 vibrate in this order (step S224). Specifically, the control device 230 selects a vibration mode in which the seat cushion vibrator 221 and the seat back vibrator 222 vibrate in this order. As a result, the seat cushion vibrator 221 and the seat back vibrator 222 vibrate in this order.

[0454] Fig.32B The control device 230 performs the driving notification process and the seat cushion vibrator 221 and the seat back vibrator 222 vibrate in this order. Fig.32B As shown, when the vehicle seat S20 is in the rotation position facing the rear of the vehicle V20, the control device 230 first vibrates the left vibrator 221L of the seat cushion vibrator 221 located most toward the front side of the seat. Next, the control device 230 vibrates the lower left vibrator 222LD of the seat back vibrator 222. Finally, the control device 230 vibrates in the order of the upper left vibrator 222LU, thereby notifying that another vehicle is approaching from the right rear of the vehicle V20. In other words, the control device 230 vibrates the vibrator 220 in such a manner that the vibration position is shifted from the vibrator 220 located more toward the right rear of the vehicle V20 than the rotation axis B20 of the vehicle seat S20 in the seat front-to-back direction toward the vibrator 220 located at the right front of the vehicle V20. As a result, the awareness of the seated person can be gradually shifted from the left front of the seat to the left rear of the seat, and the seated person can be urged to pay attention to another vehicle approaching from the right rear of the vehicle V20.

[0455] When the drive control of the vibrating body 220 in step S223 and step S224 is completed, the control device 230 ends the in-running notification process.

[0456] Next, a description will be given of a departure notification process executed by the control device 230 when the vehicle V20 starts to depart. Fig.33 2 shows the flow of the departure notification process performed by the control device 230. First, the control device 230 determines the presence and approach direction of an approaching object (for example, another vehicle approaching from the left side of the vehicle V20 that has started to depart) (step S230). More specifically, the control device 230 determines the presence and approach direction of an approaching object based on the situation recognition result output by the situation recognition unit 232.

[0457] If it is not determined that there is an approaching object (step S230 : No), the control device 230 is on standby.

[0458] On the other hand, if it is determined that there is an approaching object (step S230: Yes), the control device 230 obtains information related to the state of the vehicle seat S20 (step S231). More specifically, the control device 230 obtains signals related to the position and posture of the vehicle seat S20 from the slide position sensor 241, the rotation angle sensor 242, and the leaning angle sensor 243. In addition, in the following description, the approaching direction of the approaching object is assumed to be the left side of the vehicle V20.

[0459] Next, the control device 230 determines whether the rotational position of the vehicle seat S20 is the forward rotational position (step S232). Specifically, the control device 230 compares the rotational angle signal output by the rotational angle sensor 242 with a predetermined value to determine whether the vehicle seat S20 is facing forward of the vehicle V20.

[0460] If it is determined that the rotation position of the vehicle seat S20 is forward (step S232: Yes), the control device 230 controls so that the vibrating body 220 located on the left side of the seat of the vehicle seat S20 vibrates (step S233). Specifically, the control device 230 selects a vibration mode in which the left vibrating body 221L of the seat cushion vibrating body 221 and the upper left vibrating body 222LU and the lower left vibrating body 222LD of the seat back vibrating body 222 vibrate. As a result, the vibrating body 220 located on the left side of the seat of the vehicle seat S20 vibrates.

[0461] Fig.34A The control device 230 performs the departure notification process, and the left vibrator 221L built into the seat cushion 201, the upper left vibrator 222LU and the lower left vibrator 222LD built into the seat back 202 vibrate. Fig.34A As shown, when the vehicle seat S20 is in a rotation position facing the front of the vehicle V20, the control device 230 vibrates the vibrating body 220 located on the left side of the vehicle seat S20, thereby notifying the seated person that another vehicle is approaching from the left side of the vehicle V20 when setting off. In other words, the control device 230 vibrates the vibrating body 220 located at a position closer to the left side of the seat than the rotation axis B20 of the rotating device 205 of the vehicle seat S20. In this way, the seated person's awareness can be directed to the left side of the seat, and the seated person can be urged to pay attention to other vehicles approaching from the left side.

[0462] On the other hand, if it is determined that the rotation position of the vehicle seat S20 is not forward (step S232: No), the control device 230 controls so that the vibrating body 220 located on the right side of the vehicle seat S20 vibrates (step S234). Specifically, the control device 230 selects a vibration mode in which the right vibrating body 221R built into the seat cushion 201, the right upper vibrating body 222RU built into the seat back 202, and the right lower vibrating body 222RD vibrate. As a result, the vibrating body 220 located on the right side of the vehicle seat S20 vibrates.

[0463] In other words, when the vehicle seat S20 is in the rearward rotation position, the control device 230 selects a vibration mode in which the vibrating body 220 that vibrates when the vehicle seat S20 is in the forward rotation position and the vibrating body 220 located on the opposite side with the rotation axis B20 of the rotating device 205 as the center vibrate.

[0464] Fig.34B The control device 230 performs the departure notification process, and the right vibrator 221R built into the seat cushion 201 and the upper right vibrator 222RU and the lower right vibrator 222RD built into the seat back 202 are vibrating. Fig.34B As shown, when the vehicle seat S20 is in the rearward rotation position, the control device 230 vibrates the vibrating body 220 located on the right side of the vehicle seat S20, thereby notifying the seated person that another vehicle is approaching from the left side of the vehicle V20 when setting off. In other words, the control device 230 vibrates the vibrating body 220 located on the right side of the seat relative to the rotation axis B20 of the rotation device 205 of the vehicle seat S20. In this way, the seated person's awareness can be directed to the right side of the seat, and the seated person can be urged to pay attention to other vehicles approaching from the right side.

[0465] When the drive control of the vibrating body 220 in step S233 and step S234 is completed, the control device 230 ends the departure notification process.

[0466] Next, a description will be given of the reverse notification process executed by the control device 230 when the vehicle V20 reverses. Fig.35 FIG. 2 shows the flow of the backward notification process executed by the control device 230. Fig.35 As shown, the control device 230 first determines the presence and approach direction of an approaching object (e.g., an obstacle behind the vehicle V20 that has started to move backward) (step S240). More specifically, the control device 230 determines the presence and approach direction of an approaching object based on the situation recognition result output by the situation recognition unit 232.

[0467] If it is not determined that there is an approaching object (step S240 : No), the control device 230 is on standby.

[0468] On the other hand, if it is determined that there is an approaching object (step S240: Yes), the control device 230 obtains information related to the state of the vehicle seat S20 (step S241). More specifically, the control device 230 obtains signals related to the position and posture of the vehicle seat S20 from the slide position sensor 241, the rotation angle sensor 242, and the leaning angle sensor 243. In addition, in the following description, the approaching direction of the approaching object is assumed to be the rear of the vehicle V20.

[0469] Next, the control device 230 determines whether the rotational position of the vehicle seat S20 is the forward rotational position (step S242). Specifically, the control device 230 compares the rotational angle signal output by the rotational angle sensor 242 with a predetermined value to determine whether the vehicle seat S20 is facing forward of the vehicle V20.

[0470] If it is determined that the rotation position of the vehicle seat S20 is forward (step S242: Yes), the control device 230 controls the seat back vibrating body 222 to vibrate (step S243). Specifically, the control device 230 selects a vibration mode for vibrating the seat back vibrating body 222. As a result, the seat back vibrating body 222 vibrates.

[0471] Fig.36A The control device 230 performs the notification process when moving backward and the seat back vibrating body 222 is vibrating. Fig.36A As shown, when the vehicle seat S20 is in a rotation position facing the front of the vehicle V20, the control device 230 vibrates the seat back vibrator 222, thereby notifying the seated person of the existence of an approaching object approaching from the rear of the vehicle V20 that is moving backward. In other words, the control device 230 vibrates the vibrator 220 that is arranged at a position closer to the rear side of the seat than the rotation axis B20 of the rotation device 205 of the vehicle seat S20. Moreover, the seat back vibrator 222 vibrates at a position closer to the rear side of the seat than the body axis of the seated person. As a result, the seated person's consciousness can be directed toward the rear side of the seat, and the seated person can be urged to pay attention to the approaching object approaching from the rear side.

[0472] On the other hand, if it is determined that the rotation position of the vehicle seat S20 is not forward (step S242: No), the control device 230 controls the seat cushion vibrator 221 to vibrate (step S244). Specifically, the control device 230 selects a vibration mode for vibrating the seat cushion vibrator 221. As a result, the seat cushion vibrator 221 vibrates.

[0473] Fig.36B The control device 230 performs the notification process when moving backward and the seat cushion vibrator 221 vibrates. Fig.36B As shown, when the vehicle seat S20 is in a rotation position toward the rear of the vehicle V20, the control device 230 vibrates the seat cushion vibrator 221 to inform the seated person of the existence of an approaching object approaching from the rear side. In other words, the control device 230 vibrates the vibrator 220 located at a position closer to the rear side of the seat than the rotation axis B20 of the rotation device 205 of the vehicle seat S20. Moreover, the seat cushion vibrator 221 vibrates at a position closer to the front side of the seat than the body axis of the seated person. As a result, the seated person's consciousness can be directed toward the front side of the seat, and the seated person can be urged to pay attention to the approaching object approaching from the rear side of the vehicle V20.

[0474] When the drive control of the vibrating body 220 in step S243 and step S244 is completed, the control device 230 completes the back-off notification process.

[0475] <Modification>

[0476] The structure of the vehicle seat S20 according to one embodiment of the present invention has been described above, but the embodiment described is only an example for facilitating the understanding of the present invention and does not limit the present invention. That is, the present invention can be changed and improved without departing from its main purpose, and the present invention certainly includes its equivalents.

[0477] In the above-described embodiment, the vehicle seat S20 is described as being changeable between a rotation position facing the front of the vehicle V20 and a rotation position facing the rear of the vehicle V20, but the present invention is not limited thereto. The vehicle seat S20 may also be changed to a rotation position facing the side (right or left) of the vehicle V20 by rotating 90 degrees. When the vehicle seat S20 is rotated 90 degrees in one rotation direction, the control device 230 selects a vibration mode for vibrating the vibrating body 220 in a direction rotated 90 degrees in the other rotation direction, instead of the vibration mode selected when the vehicle seat S20 faces the front of the vehicle V20. Specifically, the control device 230, for example, vibrates the seat back vibrating body 222 when it is determined that an approaching object is approaching from the left side of the vehicle V20 and the vehicle seat S20 is in a rotation position facing the right side of the vehicle V20. Furthermore, the control device 230 vibrates the seat cushion vibrating body 221 when the vehicle seat S20 is in a rotation position facing the left side of the vehicle V20. Thus, when the vehicle seat S20 is in a rotational position toward the side of the vehicle V20, appropriate vibration notification can be performed through the vibrating body 220. The rotational position of the vehicle seat S20 toward the front of the vehicle V20 is equivalent to the first rotational position, and the rotational position of the vehicle seat S20 toward the side of the vehicle V20 is equivalent to the third rotational position. Moreover, the vibration mode selected when the vehicle seat S20 is in a rotational position toward the front of the vehicle V20 is equivalent to the first vibration notification mode, and the vibration mode selected when the vehicle seat S20 is in a rotational position toward the side of the vehicle V20 is equivalent to the third vibration notification mode.

[0478] Moreover, the rotation position of the vehicle seat S20 is not limited to the front, rear and side. It is also possible that the vehicle seat S20 can be changed to a rotation position of 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees and 315 degrees relative to the front of the vehicle V20. Moreover, it is also possible that the seated person can set the rotation position he likes. At this time, when the vehicle seat S20 is rotated to a specified angle, the control device 230 selects a vibration mode that vibrates the vibrating body 220 at the same angle in the opposite rotation direction relative to the rotation axis B20 of the rotating device 205. Thereby, when the vehicle seat S20 is located at any rotation position, the vibrating body 220 can be made to vibrate more appropriately.

[0479] <Second Modification>

[0480] Moreover, in the above-described embodiment, the position of the vibrating body 220 to be vibrated is changed corresponding to the rotational position of the vehicle seat S20, but it is not limited to this. The vibration parameters of the vibrating body 220 may also be changed corresponding to the rotational position of the vehicle seat S20. Specifically, when the vehicle seat S20 is located in a rotational position toward the rear of the vehicle V20, a vibration mode in which the vibration intensity of the vibrating body 220 is stronger (with a high vibration frequency) than when it is located in a rotational position toward the front of the vehicle V20 may be selected. Thus, even in a case where it is difficult for the seated person to grasp the surrounding conditions because the vehicle seat S20 is facing the rear of the vehicle V20, the existence of an approaching object can be strongly reminded.

[0481] Furthermore, the vibration time, vibration cycle, and vibration rhythm may be changed according to the rotation position of the vehicle seat S20. By making the vibration parameters selectable in this way, the variation of the vibration notification can be increased, and the amount of information provided by the vibration notification can be increased.

[0482] <Third Modification>

[0483] Furthermore, the control device 230 may also select a vibration mode based on the position of the vehicle seat S20 in the front-rear direction of the vehicle V20 when the vehicle seat S20 moves along the front and rear of the vehicle V20 via the track device 204. Specifically, the control device 230 may also select a vibration mode in which the vibration intensity of the vibrator 220 becomes stronger when the vehicle seat S20 is in a state of sliding significantly toward the rear of the vehicle V20 via the track device 204. Thus, even when the vehicle seat S20 is located at the rear of the vehicle V20 and the seated person has difficulty recognizing the surrounding conditions of the vehicle V20, it is possible to strongly remind the person of the approach of an approaching object.

[0484] Furthermore, the control device 230 may also select a vibration mode in which the vibration intensity of the vibrating body 220 is weakened (at a low vibration frequency) when the vehicle seat S20 is in a state of being largely slid toward the rear of the vehicle V20 via the track device 204. Thus, when the vehicle seat S20 is located at the rear of the vehicle V20 and the seated person is in a relaxed state, it is possible to suppress the situation in which the seated person feels uncomfortable due to the vibration of the vibrating body 220.

[0485] <Fourth Modification>

[0486] Furthermore, the control device 230 may select a vibration mode based on the posture of the vehicle seat S20, that is, the tilting angle of the seat back 202 relative to the seat cushion 201. Specifically, the control device 230 may select a vibration mode in which the vibration intensity of the vibrator 220 becomes stronger when the seat back 202 is tilted greatly toward the rear of the vehicle seat S20 by the reclining device 206. Thus, even when the seat back 202 is tilted toward the rear and the seated person has difficulty recognizing the surrounding conditions of the vehicle V20, it is possible to strongly warn the person of the approaching object.

[0487] Furthermore, when the seat back 202 is tilted greatly toward the rear of the vehicle seat S20, the control device 230 may select a vibration mode in which the vibration intensity of the vibrating body 220 is weakened. Thus, when the seat back 202 is tilted toward the rear of the vehicle S20 and the seat occupant is in a relaxed state, it is possible to suppress the seat occupant from feeling uncomfortable due to the vibration of the vibrating body 220.

[0488] <Fifth Modification>

[0489] Furthermore, the control device 230 may also change the speaker 244 that outputs the sound signal in accordance with the rotational position of the vehicle seat S20. Specifically, in the case where it is determined that an approaching object is approaching from the right side of the vehicle V20, when the vehicle seat S20 is located in a rotational position facing the front of the vehicle V20, a warning sound is output from the right speaker 244R. On the other hand, when the vehicle seat S20 is located in a rotational position facing the rear of the vehicle V20, a warning sound is output from the left speaker 244L. In other words, the control device 230 outputs a warning sound from the speaker 244 that is located in the direction in which the approaching object approaches when viewed from the seated person and is located in the same direction as the vibrating body 220 that is driven and controlled to vibrate. By combining the right speaker 244R and the left speaker 244L with the vibration notification by the vibrating body 220 in this way, it is possible to more effectively urge attention to the approaching object.

[0490] <Second embodiment>

[0491] Below, refer to Fig.37 and Fig.38 The vehicle seat S20 of the second example of the second embodiment is described. The vehicle seat S20 of the second embodiment has a seat cushion 201, a seat back 202, a headrest 203, an armrest 2107, and a leg support 2108 as main structures. In addition, the same reference numerals are attached to the components having the same shape and structure as those in the above-mentioned embodiment, and the description thereof is omitted so that the differences from the components having different shapes and structures become clear.

[0492] In the seat back 202, a seat back vibrator 222 used as a notification member for the seated person is built in. The seat back vibrator 222 has an upper right vibrator 222RU, a lower right vibrator 222RD, an upper left vibrator 222LU, a lower left vibrator 222LD, and a center vibrator 2122C as main structures. The upper right vibrator 222RU, the lower right vibrator 222RD, the upper left vibrator 222LU, and the lower left vibrator 222LD are eccentric motors. The eccentric motor generates a small amplitude vibration by rotating at a high frequency.

[0493] On the other hand, the central vibrator 2122C is a piezoelectric vibrator. A piezoelectric vibrator generates gentle vibrations by linearly vibrating at a relatively low frequency.

[0494] By building multiple types of vibrators 220 in the seat back 202 in this way, it is possible to achieve an improvement in the variation of vibration notification. To give a specific example, the approach of an external obstacle can be notified by vibration through an eccentric motor, and on the other hand, the guidance information output by the navigation device mounted on the vehicle V20 or the music output by the audio and video device 2146 can be notified by a piezoelectric vibrator. To explain in more detail, the control device 2130 described later converts the guidance information output by the navigation device into a coded signal (Morse signal) coded using long and short dots, and performs vibration notification via a piezoelectric vibrator. In this way, it is possible to transmit guidance information to seated persons who are difficult to identify visually and auditorily. Moreover, the control device 2130 vibrates the piezoelectric vibrator in synchronization with the timing of the bass output of the music output by the audio and video device 2146. As a result, the seated person can feel the sense of presence of the music output by the audio and video device. In addition, the seat back vibrator 222 is not limited to the combination of an eccentric motor and a piezoelectric vibrator. The seat back vibrating body 222 may also be combined with a linear resonance actuator having a magnet and a winding as a main structure.

[0495] In the headrest 203, a headrest vibrator 2123 used as a notification component is built in. The headrest vibrator 2123 has an upper vibrator 2123U and a lower vibrator 2123D as main structures. The upper vibrator 2123U is an eccentric motor. On the other hand, the lower vibrator 2123D is a piezoelectric vibrator, but is not limited to this. The lower vibrator 2123D can also be a linear resonance actuator.

[0496] In the armrest 2107, an armrest vibrator 2124 used as a notification component is built in. The armrest vibrator 2124 has a right vibrator 2124R and a left vibrator 2124L as main structures. The right vibrator 2124R and the left vibrator 2124L are eccentric motors, but are not limited to this. The right vibrator 2124R and the left vibrator 2124L may also be a piezoelectric vibrator or a linear resonance actuator. The armrest vibrator 2124 is equivalent to an arm vibrator.

[0497] The leg support 2108 has a built-in leg support vibrator 2125 used as a notification component. The leg support vibrator 2125 has a right vibrator 2125R and a left vibrator 2125L as main structures. The right vibrator 2125R and the left vibrator 2125L are eccentric motors, but are not limited to this. The right vibrator 2125R and the left vibrator 2125L may also be a piezoelectric vibrator or a linear resonance actuator. The leg support vibrator 2125 is equivalent to a foot vibrator.

[0498] The seat cushion pad 201 is the same as that in the above-described embodiment, and thus detailed description thereof will be omitted.

[0499] Next, the functional structure of the vehicle seat S20 according to the second embodiment will be described. Fig.38 2 shows the functional structure of the vehicle seat S20. Fig.38 As shown, the control device 2130 responsible for controlling the vehicle seat S20 is connected to an external sensor 240, a sliding position sensor 241, a rotation angle sensor 242, a leaning angle sensor 243, a bio-information sensor 2145, a sound and imaging device 2146, a seat cushion vibrator 221, a seat back vibrator 222, a headrest vibrator 2123, an armrest vibrator 2124, a leg support vibrator 2125 and a speaker 244.

[0500] The external sensor 240 , the slide position sensor 241 , the rotation angle sensor 242 , the leaning angle sensor 243 , and the speaker 244 have the same structure as those in the above-mentioned embodiment, and thus detailed description thereof will be omitted.

[0501] The biometric information sensor 2145 is a detection component that can obtain the biometric information of the seated person. Specifically, the biometric information sensor 2145 is an acceleration sensor that detects the heart rate and breathing movements of the seated person, thereby measuring the heart rate and breathing rate of the seated person. In addition, the biometric information sensor 2145 can also be a temperature sensor that can measure the body temperature of the seated person. In this way, the biometric information of the seated person can be obtained and monitored through the biometric information sensor 2145, and when an abnormality is detected, a warning signal is output according to a predetermined rule.

[0502] The biometric information sensor 2145 is built into the seat cushion 201 , but the present invention is not limited thereto. The biometric information sensor 2145 may also be built into the seat back 202 .

[0503] The audio-visual device 2146 is an electronic device capable of reproducing and outputting music and images. The audio-visual device 2146 has an audio output device and a display device. By reproducing information recorded on a recording medium, the audio output device outputs audio signals such as music, and displays video signals such as images on the display device.

[0504] The audio and video device 2146 may be an electronic device integrated with the navigation device installed in the vehicle V20, or may be independently configured. Furthermore, the audio and video device 2146 may be a mobile terminal that can be carried by the seated person.

[0505] The seat cushion vibrator 221, the seat back vibrator 222, the headrest vibrator 2123, the armrest vibrator 2124, and the leg support vibrator 2125 are as shown in FIG. Fig.37 As described above, the vibration notifying member includes an eccentric motor and a piezoelectric vibrator.

[0506] The vibration mode determination unit 2133 of the second embodiment selects a vibration mode that causes at least one of the plurality of armrest vibrators 2124 to vibrate in a prescribed order and with prescribed vibration parameters based on the position and posture of the seat body. Specifically, the control device 2130, for example, vibrates the left vibrator 2124L of the armrest vibrators 2124 when it is determined that an approaching object is approaching from the left side of the vehicle V20 and the vehicle seat S20 is in a rotation position facing the front of the vehicle V20. Furthermore, the control device 2130 vibrates the right vibrator 2124R of the armrest vibrators 2124 when the vehicle seat S20 is in a rotation position facing the rear of the vehicle V20. Thus, regardless of the rotation position of the seat body, the seat occupant's awareness can be directed to the left side of the vehicle V20, and the seat occupant can be urged to pay attention to the approaching object approaching from the left side of the vehicle V20.

[0507] Furthermore, the vibration mode determination unit 2133 of the second embodiment selects a vibration mode that causes at least one of the plurality of leg support vibrators 2125 to vibrate in a prescribed order and with prescribed vibration parameters based on the position and posture of the seat body. Specifically, when the control device 2130 determines that an approaching object is approaching from the right side of the vehicle V20 and the vehicle seat S20 is in a rotation position facing the front of the vehicle V20, for example, the right vibrator 2125R of the right vibrator 2125R and the left vibrator 2125L vibrates. Furthermore, when the vehicle seat S20 is in a rotation position facing the rear of the vehicle V20, the control device 2130 vibrates the left vibrator 2125L. Thus, regardless of the rotation position of the seat body, the occupant's awareness can be directed to the right side of the vehicle V20, and the occupant can be urged to pay attention to the approaching object approaching from the right side.

[0508] Moreover, each control device 2130 of a plurality of vehicle seats S20 provided in the vehicle V20 may also accept input of setting information by a passenger, and perform specific vibration notification based on the input setting information. To illustrate by taking a specific example, it is assumed that a plurality of passengers with different destinations are on board the vehicle V20. The control device 2130 built into each vehicle seat S20 accepts input of a destination from each passenger in advance. The control device 2130 obtains the position information of the vehicle V20 from a navigation device integrally constituted with the audio and video device 2146, and determines whether the vehicle V20 has arrived within a prescribed distance from the destination of the seated person. When the control device 2130 determines that the vehicle V20 has arrived within a prescribed distance from the destination of the seated person, the control device 2130 performs a vibration notification to the seated person. In this way, it is possible to suppress the situation where useless vibration notifications are made to other seated persons.

[0509] Furthermore, the control device 2130 may also vibrate to notify other passengers when receiving dissatisfaction from other passengers in the vehicle V20. The control devices 2130 built into each vehicle seat S20 are connected to each other for communication, so as to anonymously notify information related to dissatisfaction. Thus, the vibrator 220 can be used to notify other passengers of dissatisfaction. Therefore, the seated person can deal with dissatisfaction without being known by other passengers.

[0510] Furthermore, the control device 2130 may acquire biological information of a passenger outputted from the biological information sensor 2145 built in the vehicle seat S20, and perform vibration notification of abnormality of the biological information only to preset seated persons based on the biological information.

[0511] Furthermore, the control device 2130 may also determine whether vibration notification is necessary for each passenger based on the setting information input in the past. In other words, the control device 2130 may also store the setting information input in the past as setting history information, and generate a determination condition for determining whether vibration notification is necessary based on the setting history information.

[0512] <Other Modifications>

[0513] In the above embodiment, the control device 230 is described as being built in the vehicle seat S20, but the present invention is not limited thereto. The control device 230 may also be provided in the vehicle V20 and communicate with the electrical components built in the vehicle seat S20 to control the vehicle seat S20.

[0514] Furthermore, in the above-described embodiment, the control device 230 is described as performing vibration notification through the vibrating body 220, but notification may be performed in combination with notification components other than the vibrating body 220. As a specific example, the control device 230 may also send a notification signal toward the passenger's mobile terminal, and perform notification through the mobile terminal in combination with the vibration notification through the vibrating body 220. More specifically, the control device 230 notifies the mobile terminal of the detailed information together with the vibration notification through the vibrating body 220. Similarly, detailed information may be sent to the display device D20 provided in the vehicle V20, and notification may be performed in combination with the display device D20.

[0515] Furthermore, when the vibration mode is changed due to a change in the position or posture of the seat body, the control device 230 may send the change in the vibration mode to the passenger's mobile terminal or display device D20. By using the passenger's mobile terminal or display device D20, various notification methods such as sound, text, image, and lighting can be used.

[0516] Furthermore, when the vibration mode cannot be changed due to an abnormality in the device, etc., the control device 230 may send this notice to the passenger's mobile terminal or display device D20.

[0517] <<Third Embodiment>>

[0518] Next, a third embodiment of the present invention will be described.

[0519] <<Technical Field>>

[0520] A third embodiment relates to a vehicle seat, and more particularly to a vehicle seat including a vibrating body.

[0521] <<Background Technology>>

[0522] Conventionally, there is a known technique of configuring a vibrator on a seat back or seat cushion of a vehicle seat (see, for example, Japanese Patent Laid-Open No. 2000-225877). By vibrating the vibrator based on a signal obtained from a sensor, for example, the approach of another vehicle or obstacle can be notified to the occupant.

[0523] <<Disclosure of the Invention>>

[0524] <<Problems to be solved by the invention>>

[0525] However, conventionally, sufficient consideration has not been given to arranging the vibrator at an appropriate position in a seat back or a seat cushion, and it is required to arrange the vibrator at an optimal position for the seated person, for example, based on optimization of the positional relationship with functional parts such as sensors and heaters.

[0526] Furthermore, as another problem, efforts must be made to more appropriately transmit the vibration generated by the vibrating body to the seated person.

[0527] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a vehicle seat in which a vibrating body is arranged at a more appropriate position.

[0528] <<Technical means to solve the problem>>

[0529] The problem is solved by the following method, that is, according to the vehicle seat of the present invention, a vehicle seat has a cushion component, and the vehicle seat includes: a functional part, which is arranged on the cushion component; and at least one vibrator, which is arranged on the cushion component and generates vibration, and the vibrator is configured at a position where at least a portion of the cushion component does not overlap with the functional part when the cushion component is observed from the seating surface.

[0530] According to the vehicle seat of the present invention configured as above, a part of the vibrator is arranged at a position where at least a part does not overlap with the functional parts when viewed from the seat surface, thereby suppressing the performance degradation of the functional parts. Therefore, a vehicle seat in which the vibrator is arranged at a more appropriate position can be provided.

[0603] <Pad through hole 343>

[0604] A pad through hole 343 is formed along the first vertical insertion hanging groove 342 in a portion of the first vertical insertion hanging groove 342. The pad through hole 343 facilitates deformation of the back pad 340. Furthermore, the pad through hole 343 can absorb deformation of the back pad 340 caused by the vibrating body 360 described later.

[0605] Furthermore, when the vehicle seat S30 is provided with a blower 335 for sending out air, a duct through-hole 338 through which the duct 336 is inserted may be formed in the back pad 340 .

[0606] <Storage recess 344>

[0607] like Fig.44 and Fig.47 As shown, a receiving recess 344 for receiving the vibrating body 360 on the back side is formed on the seating surface 340a of the back pad 340. The vibrating body 360 can be attached by inserting the vibrating body 360 into the receiving recess 344.

[0608] After the vibrator 360 is inserted into the housing recess 344, the plate 345 is placed on the vibrator 360 to seal the housing recess 344. The plate 345 is fixed by a fixing tape 346.

The second transverse hanging groove 351 is equivalent to the transverse hanging groove of the present invention, and the second longitudinal hanging groove 352 is equivalent to the longitudinal hanging groove of the present invention.

[0615] The second longitudinal insertion hanging groove 352 is disposed between the main body 302a and the bank portions 302b provided on the left and right of the seat cushion 302. The second transverse insertion hanging groove 351 is provided so as to connect the two second longitudinal insertion hanging grooves 352.

[0616] The seating surface 350a of the cushion pad 350 is provided with a receiving recess 354 for receiving the vibrating body 361 on the cushion pad side. The vibrating body 361 can be installed by inserting the vibrating body 361 into the receiving recess 354. Fig.46 and Fig.48A As shown, a harness hole 357 is formed on the bottom surface of the storage recess 354 , and the harness 365 extending from the vibrator 361 is passed through, so that the harness 365 can be introduced into the bottom surface 350 b of the cushion pad 350 .

[0617] After the vibrator 361 is inserted into the storage recess 354, a plate 355 is placed on the vibrator 361 to seal the storage recess 344. The plate 355 is fixed by a fixing belt 356. Fig.46 and Fig.48A As shown, a harness hole 357 is formed on the bottom surface of the storage recess 354 , and the harness 365 extending from the vibrator 361 is passed through, so that the harness 365 can be introduced into the bottom surface 350 b of the cushion pad 350 .

[0618] in addition, Fig.48A In the illustrated cushion 350, a harness hole 357 is formed on the bottom surface of the storage recess 354, but the position of the harness hole 357 is not limited thereto and may also be Fig.48B As shown in the figure, the harness hole 357' is formed in the side wall and passes through the second horizontal hanging groove 351, thereby forming the harness hole 357' extending from the bottom of the second horizontal hanging groove 351 to the bottom surface 350b. In addition, the harness hole 357' can also use the hanging hole formed in the second horizontal hanging groove 351.

[0619] <Positions of vibrating bodies 360 and 361>

[0620] Hereinafter, the arrangement of the vibrating body 360 of the back pad 340 and the vibrating body 361 of the cushion pad 350 will be described with reference to the drawings.

[0621] Conventionally, in order to notify the occupant, a vibrator is disposed on the seat back or the seat cushion of the vehicle seat, but sufficient consideration has not been given to arranging the vibrator at an appropriate position.

[0622] In the vehicle seat S30 of this embodiment, two vibrating bodies 360 for generating vibrations are provided in the back pad 340. Fig.41 As shown, the two vibrators 360 are arranged at positions where at least a portion thereof does not overlap with the pressure receiving member 315 when the vehicle seat S30 is viewed from the front.

[0623] Specifically, the two vibrators 360 are arranged at positions overlapping with the opening 315 c located on the side of the plate-shaped member 3152 of the pressure-receiving member 315 and above the first side portion 3153 in a front view.

[0624] By configuring in this way, for example, when the occupant is seated or when the vehicle is involved in a frontal collision, the occupant sinks into the cushion 350, but at this time, the vibrating body 360 does not prevent the occupant from sinking. That is, when sinking, the occupant presses the vibrating body 360 backward, but the movement of the vibrating body 360 is suppressed from being hindered by the pressure-receiving member 315, so the occupant's sinking is not prevented. By configuring the vibrating body 360 in consideration of the position of the pressure-receiving member 315, it is possible to provide a vehicle seat S30 in which the vibrating body 360 is arranged at an appropriate position.

[0625] Furthermore, as described above, the pressure receiving member 315 is configured so that Fig.41 Although the vibrator 360 can move within the movable range R (prescribed range) shown in FIG. 1 , the vibrator 360 is arranged so as to be located outside the movable range R. Therefore, even if the pressure-receiving member 315 moves, the vibrator 360 does not interfere with the pressure-receiving member 315. By configuring in this way, it is possible to suppress an increase in discomfort caused by the movement of the pressure-receiving member 315.

[0626] Moreover, if Fig.43 As shown in FIG. 1 , the vibrating body 360 is arranged at a position overlapping with the pad through hole 343 formed in the cushion pad 350 in the seat width direction. In other words, the vibrating body 360 is arranged in a manner so as to be at substantially the same height position as the pad through hole 343 in the seat vertical direction. By arranging in this way, the deformation of the back pad 340 caused by the vibrating body 360 can be absorbed by the pad through hole 343.

[0627] Moreover, if Fig.43As shown, the vibrator 360 is arranged to be located below the first horizontal insertion hanging groove 341 extending in the seat width direction. In addition, the vibrator 360 is arranged inside the first vertical insertion hanging groove 342 extending in the seat vertical direction in the seat width direction. In other words, the vibrator 360 is arranged to be sandwiched between the two first vertical insertion hanging grooves 342.

[0628] By disposing the vibrating body 360 in this way, for example, the influence of the first transverse insertion hanging groove 341 and the first longitudinal insertion hanging groove 342 can be suppressed, and the discomfort caused to the seated person can be suppressed.

[0629] Furthermore, when a blower is provided in the vehicle seat S30 so as to blow air from the seat back 301, Fig.43 As shown, a duct 336 is disposed on the upper portion of the seat back 301. In this case, the vibrator 360 can be disposed at a position avoiding the duct 336 provided on the cushion 350. By being disposed at a position avoiding the duct 336 extending from the blower 335, the influence on the air sent from the blower can be suppressed.

[0630] In addition, the vibrating body 360 may be arranged at a position avoiding not only the duct 336 but also the opening portion of the blower or the blower mounting portion where the blower is mounted.

[0631] <Sensor device 370>

[0632] Next, the relationship between the vibrating body 361 and the sensor device 370 will be described. Fig.49A FIG. 3 is a top view showing the seat cushion 302 equipped with the sensor device 370. In addition, the seat cushion 302 is shown in a state where the cover 306 has been removed. Fig.49A As shown, a sensor device 370 is disposed in the cushion 350 of the seat cushion 302 .

[0633] The sensor device 370 is a seat belt reminder switch, which includes a plurality of sensor parts 371 for detecting the state of the seated person, a connection part 372 connecting the plurality of sensor parts 371 and the harness 365, and a harness 373 extending from the connection part 372. The harness 373 passes through a harness hole 374 formed in the cushion 350 and is connected to an ECU or the like. The sensor part 371 is a pressure sensor, but may also be an electrostatic capacitance sensor, and is a biological information detection device for detecting biological information of the seated person. In addition, the sensor device 370 is equivalent to the functional part of the present invention.

[0634] like Fig.49AAs shown in FIG. 1 , the vibrating body 361 and the storage recess 354 storing the vibrating body 361 (hereinafter referred to as the vibrating body 361, etc.) are arranged at a position away from the sensor device 370. In other words, the vibrating body 361, etc. are arranged at a position that does not overlap with the sensor device 370 when the vehicle seat S30 is viewed from above. Specifically, the vibrating body 361, etc. are arranged at a predetermined distance from the sensor device 370 in the seat width direction. By arranging the vibrating body 361, etc. at a position away from the sensor device 370, it is possible to suppress the degradation of the sensor performance.

[0635] Furthermore, the vibrator 361 and the like may be arranged at a position away from the sensor portion 371. By avoiding the sensor portion 371, it is possible to suppress a decrease in sensor performance.

[0636] Furthermore, the vibrating body 361 and the like can be arranged at a position avoiding the connection portion 372 connecting the sensor portions 371. By arranging the vibrating body 361 and the like avoiding the connection portion 372, it is possible to suppress a decrease in the current carrying performance.

[0637] Furthermore, the vibrator 361 and the like can be arranged at a position away from the entire sensor including the sensor portion and the connection portion, thereby suppressing a decrease in sensor performance and electrical conductivity.

[0638] Furthermore, the vibrating body 361 and the like can be arranged at a position avoiding the harness hole 374. By arranging the vibrating body 361 avoiding the harness hole 374, the ease of assembly of the harness 373 is improved.

[0639] As described above, the harness hole 357 through which the harness 365 of the vibrator 361 passes is formed at the bottom of the storage recess 354 , but the harness hole 374 through which the harness 373 of the sensor passes may be used together with the harness hole 357 .

[0640] The harness 365 of the vibrator 361 and the harness 373 of the sensor device 370 passing through the bottom surface side can be bundled together on the bottom surface side. By bundling together, the harness can be arranged compactly.

[0641] Furthermore, the vibrating body 361 and the receiving recess 354 may also be Fig.49B The seat cushion 302' is arranged to overlap with the sensor device 370. By arranging the overlapped parts, a compact arrangement of the plurality of components can be achieved.

[0642] Furthermore, when the cushion pad 350' includes a pad body and an upper pad part combined with the pad body, the vibrator 361 and the sensor device 370 can be arranged on the upper pad part and then assembled to the pad body. By assembling in this way, it is possible to achieve easy assembly.

[0643] In addition, although the vibration body 3061 disposed on the seat cushion 302 is described as an example, the vibration body 360 and the storage recess 344 disposed on the seat back 301 can also be disposed at a position avoiding the sensor device 370 disposed on the seat back 301. That is, when the vehicle seat S30 is viewed from the front (seen from the seat surface), the vibration body 360 and the like can be disposed at a position that does not overlap with the sensor device 370.

[0644] <Heater device 380>

[0645] Next, the relationship between the vibrator 361 and the heater device 380 will be described. Fig.50 1 is a plan view showing a seat cushion pad 302A provided with a heater device 380. The seat cushion pad 302 is shown in a state where a cover 306 is removed.

[0646] A heater device 380 is disposed on the cushion pad 350A of the seat cushion pad 302A.

[0647] The heater device 380 includes a base fabric 382 and a heating wire portion 381 as a heat source disposed on the base fabric 382. The heater device 380 corresponds to a functional component of the present invention.

[0648] The vibrator 361 may be arranged at a position overlapping with the heater device 380 in a plan view. By arranging the vibrator 361 in an overlapping manner, it is possible to suppress a decrease in the performance of the vibrator 361 due to low temperature.

[0649] The vibrating body 361 may be Fig.50 The vibrating body 361Aa shown in FIG. 1 is arranged at a position overlapping only the base fabric 382. Fig.50 As shown in FIG. 361, the vibrator 361Ab is arranged at a position overlapping the base fabric 382 and the heating wire portion 381. By arranging in this way, it is possible to suppress the performance degradation of the vibrator 361 due to low temperature.

[0650] Furthermore, when the cushion pad 350A includes a pad body and an upper pad portion combined with the pad body, the vibrator 361 and the heater device 380 may be arranged on the upper pad portion and then assembled to the pad body. By assembling in this way, it is possible to facilitate assembly.

[0651] like Fig.51 As shown, the vibrator 361 is fixed by being stored in the storage recess 354, but when it is arranged at a position overlapping with the heater device 380, a cover with a high heat insulation effect can be provided. By providing a cover 383 with a high heat insulation effect, it is possible to suppress the decrease in the heating performance of the heater device 380. In addition, the base fabric 382 is bonded to the cushion pad 350A, so a fixing tape is not required.

[0652] The wire harness of the vibrator 361 and the wire harness of the heater device (not shown) can be bundled together on the bottom surface side of the cushion pad. By bundling the wire harnesses, a compact arrangement of the wire harnesses can be achieved.

[0653] Furthermore, the vibrator 361 may be arranged away from the heater device 380. Fig.52 The vibrating body 361Ac of the seat cushion 302A' shown in the figure is arranged to completely avoid the heater device 380. In other words, the vibrating body 361 may be arranged at a position that does not overlap with the heater device 380 in a plan view.

[0654] The vibrating body 361 may also be Fig.52 As shown in the figure, the vibrating body 361Ad is arranged so that a part does not overlap with the heater device 380.

[0655] By arranging the vibrating body 361 away from the heater device 380 , it is possible to suppress a decrease in the performance of the heater device 380 .

[0656] Moreover, it can also be like Fig.53 As shown in the vibrating body 360Aa of the seat back 301A, a part of the vibrating body 360 is arranged at a position overlapping with the base fabric 382 of the heater device 380 arranged on the seat back 301A in front view.

[0657] Moreover, the vibrating body 360 can also be like Fig.53 As shown in FIG. 360 , the vibrator 360Ab is arranged at a position overlapping the base fabric 382 and the heating wire portion 381. The performance degradation of the vibrator 360 due to low temperature can be suppressed.

[0658] Moreover, the vibrating body 360 can also be like Fig.54 The vibrator 360Ac shown in the figure is arranged to avoid the heater device 380. That is, the vibrator 360 can be arranged at a position that does not overlap with the heater device 380 when viewed from the front.

[0659] Moreover, in Fig.54 When the heater device 380 is divided into two parts as in the seat back 301A' shown in the figure, the heater device 380 may be divided into two parts as in the seat back 301A' shown in the figure. Fig.54 As shown in FIG. 3 , the vibrator 360 is arranged in the gap between the heater device 380 and away from the heater device 380 .

[0660] By arranging the vibrating body 361 away from the heater device 380 , it is possible to suppress a decrease in the performance of the heater device 380 .

[0661] <Air chamber 390>

[0662] Next, the relationship between the vibrating body 361 and the air chamber 390 provided on the cushion pad 350B will be described. Fig.551 is a plan view showing a seat cushion pad 302B provided with an air chamber 390. In addition, the seat cushion pad 302B is shown in a state where the cover 306 is removed.

[0663] The air chamber 390 is a bag body that can be expanded by injecting air, and the shape of the seat or the posture of the seated person can be changed by the expansion of the air chamber 390. In addition, the air chamber 390 is equivalent to the functional part of the present invention.

[0664] The vibrating body 361 may be Fig.55 The vibrating body 361Ba is arranged at a position where a part of the vibrating body 361Ba does not overlap with the air chamber 390 when viewed from the top, that is, when viewed from the seat surface of the seat cushion 302B. Fig.55 The vibrator 361Bb is arranged at a position where the front portion does not overlap with the air chamber 390. In other words, the vibrator 361 can be arranged at a position away from the air chamber 390. By arranging the vibrator 361 at a position away from the air chamber, it is possible to suppress the performance degradation of the air chamber.

[0665] Furthermore, the vibrating body 361 may also be Fig.56 The vibrating bodies 361Bc and 361Bd of the cushion pad 302B' shown in the figure are arranged so as to overlap with the air chamber 390. By arranging the vibrating body 361 in this way, the vibrating body 361 can be arranged compactly.

[0666] Furthermore, the vibrating body 361 may also be Fig.57A As shown in FIG. 3 , the vibrating body 361 is arranged on the air chamber 390. By arranging the vibrating body 361 on the air chamber 390, the vibration is easily transmitted to the seated person.

[0667] Furthermore, the vibrating body 361 may also be Fig.57B As shown, in the cushion pad 302B', the vibrator 361 is fitted into the housing recess 354 and arranged below the air chamber 390 of the vibrator 361Ba. The vibrator 361 can be arranged compactly.

[0668] Furthermore, the distance between the air chambers 390 may be changed in accordance with the interval between the vibrators 361 .

[0669] Furthermore, when the cushion pad 350B includes a pad body and an upper pad portion combined with the pad body, the vibrator 361 and the air chamber 390 can be arranged on the upper pad portion and then assembled to the pad body. By assembling in this way, it is possible to facilitate assembly.

[0670] Furthermore, the wire harness 365 of the vibrating body 361 and the wire harness (not shown) of the air chamber 390 can be bundled together on the bottom surface side of the cushion pad. By bundling the wire harnesses, a compact arrangement of the wire harnesses can be achieved.

[0671] Moreover, it can also be like Fig.58As shown in the vibrating body 360Ba of the seat back 301B, a part of the vibrating body 360 is arranged at a position that does not overlap with the air chamber 390 arranged in the seat back 301B when viewed from the seat surface, that is, when viewed from the front.

[0672] Moreover, the vibrating body 360 can also be like Fig.58 As shown in FIG. 3 , the vibrating body 360Bb is arranged at a position overlapping the air chamber 390 when viewed from the seat surface, that is, when viewed from the front. The vibrating body 360 can be arranged compactly.

[0673] Furthermore, by being arranged so as to overlap with the air chamber 391 mounted on the bank portion of the seat back 301B in the seat width direction, the occupant can easily feel the vibration.

[0674] Moreover, it can also be like Fig.59 As shown in the seat back 301B', the horizontally long air chamber 392 is arranged on the back cushion 340B. Fig.59 The vibrating bodies 360Bc and 360Bd are arranged at a position overlapping with the air chamber 392. By setting the vibrating body 360 in a horizontally long shape like the air chamber 392, it is easy to arrange the vibrating body 360 in an overlapping manner.

[0675] <Relationship with the hanging groove>

[0676] use Fig.60 To illustrate the relationship between the vibrating body and the embedded hanging groove. Fig.60 is a top view of a cushion pad 350C of a seat cushion pad 302C, Fig.61 It is along Fig.60 Cross-sectional view of the FF line.

[0677] The vibrating body 361 may be Fig.60 The vibrating body 361C is arranged at a position overlapping with the hanging groove formed in the cushion pad 350C, especially the second horizontal hanging groove 351, when viewed from above. By arranging in this way, it is possible to realize a compact arrangement of the vibrating body 361. The vibrating body 361 may also be arranged at a position overlapping with the second vertical hanging groove 352 when viewed from above.

[0678] The vibrator 361 may be arranged at a position avoiding the hanging groove. This can suppress the performance degradation of the vibrator 361. The vibrator 361 may be arranged at a position avoiding the clamping member 367 for fixing the hanging skin 306. This can suppress the performance degradation of the vibrator.

[0679] The vibrator may be arranged near a region sandwiched by a plurality of skin fixing portions (portions provided with clamping members or C-shaped rings, etc.) for fixing the skin. This can suppress sagging of the skin.

[0680] In addition, sometimes the skin is hung with hanging wires, but there is a risk that vibration cannot be transmitted. Therefore, the vibrator 361 can be used only when the skin 306 is fixed with a clamping member 367 instead of the hanging wires.

[0681] Furthermore, the storage recess 354 for storing the vibrator 361 can be arranged at a position overlapping with the hanging groove. Furthermore, the storage recess 354 can be arranged at a position overlapping with the bottom or side of the hanging groove. The vibrator 361 can be arranged compactly.

[0682] Furthermore, although the storage recess 354 overlaps with the hanging groove, the vibrator 361 may be arranged at a position away from the hanging groove, so that the performance of the vibrator can be suppressed from being degraded.

[0683] <Relationship with variable bank 3121>

[0684] Some vehicle seats have a variable bank 3121 that allows the bank of the cushion to move. Fig.62 The relationship between the vibrating body 361 and the variable bank 3121 will be described.

[0685] Fig.62 It is a top view of a seat cushion 302D having variable banks 3121 whose positions can be changed on the left and right sides. In the seat cushion 302D, the banks can be opened or closed in the left and right directions by a movable mechanism 3122. The variable banks 3121 are equivalent to the functional parts of the present invention.

[0686] The vibrating body 361 may be Fig.62 As shown in FIG. 3 , the vibrating body 361Da is arranged at a position overlapping with the movable mechanism 3122 provided inside the variable bank portion 3121 when viewed from the seat surface, that is, in a plan view. The vibrating body 361 can be arranged compactly.

[0687] Furthermore, the vibrating body 361 may be Fig.62 The vibrating body 361Db may be arranged at a position avoiding the movable mechanism 3122. That is, it may be arranged at a position not overlapping with the movable mechanism 3122 in a plan view. By arranging the vibrating body 361 in this way, the influence on the movable mechanism 3122 can be suppressed.

[0688] <Relationship with front and rear adjustment mechanism 3123>

[0689] Some vehicle seats have a front-rear adjustment function that allows the front end of the cushion pad to extend forward. Fig.63 2 is a cross-sectional view schematically showing the structure of a seat cushion 302E having a front-rear adjustment mechanism 3123 at the front. Fig.63The front end of the seat cushion 302E is moved as shown by the double arrow A. The cushion 350E is supported by the fixing portion 3124. In addition, the front-rear adjustment mechanism 3123 is equivalent to the functional part of the present invention.

[0690] like Fig.63 As shown, in the vibrator 361, the movable part of the front-back adjustment mechanism 3123 is arranged further back than the storage recess 3125 (the position of the front end of the cushion 350E not extended). The rear of the cushion 350 is not moved by the front-back adjustment mechanism 3123, so the vibrator 361 can be easily installed.

[0691] <Relationship with airbags>

[0692] Some vehicle seats are provided with airbags at the side portions thereof. The airbags include side airbags provided at the side portions of the seat back and cushion airbags arranged in front of the upper surface of the cushion airbag. Fig.64 301C is a front view showing a seat back 301C provided with a side airbag module 3100. Fig.65 3 is a top view showing a seat cushion 302F provided with a cushion airbag module 3101. In addition, the cover 306 is removed and shown. In addition, the airbag corresponds to the functional part of the present invention.

[0693] In the seat back 301C, a side airbag module 3100 is provided on the left side, and a tear line (a rupture portion) is formed on the side thereof. Fig.63 The vibrating body 360 is arranged at a position avoiding the side airbag module 3100, as shown in the vibrating body 360Ca. It is also arranged at a position avoiding the tear line 3102 in the up-down direction. In other words, it is arranged at a position that does not overlap in the seat width direction, that is, it is arranged above or below the tear line 3102. By arranging the vibrating body 360 in this way, the deployment of the side airbag module 3100 is not hindered.

[0694] like Fig.65 As shown in FIG. 1 , a cushion airbag module 3101 of a cushion airbag is arranged in front of the upper surface of the seat cushion 302F. Fig.65 As shown in FIG. 3 , the vibrating body 361Fa is arranged at a position avoiding the bag bulging region 3104 of the cushion airbag module 3101. By arranging in this way, the deployment of the cushion airbag module 3101 is not hindered.

[0695] <Relationship with lighting>

[0696] Some vehicle seats may be provided with lighting on the side portions of the seat cushions. Fig.6631 is a top view of a seat cushion 302G provided with a lighting 3110. The seat cushion 302G is shown in a state where the cover 306 has been removed. The lighting 3110 corresponds to a functional part of the present invention.

[0697] The vibrating body 361 provided on the seat cushion 302G is Fig.65 As shown in the figure, the vibrator 361Ga is arranged near the lighting 3110 in the seat width direction. That is, the lighting 3110 is arranged in front of, to the side of, or above the vibrator 361Ga. In the figure, the vibrator 361Ga is arranged at a position overlapping with the lighting 3110 in the seat width direction.

[0698] By lighting the lighting 3110 located near the vibrator 361Ga when the vibrator 361Ga is operating, it is easy for people to know that the vibrator 361Ga is operating.

[0699] <Relationship with pads of different hardness>

[0700] Some vehicle seats have a back pad or a cushion pad that includes a plurality of cushion materials having different hardnesses.

[0701] Fig.67 302H is a top view showing a seat cushion pad 302H including cushion materials of different hardness. The seat cushion pad 302H is shown in a state where the outer skin 306 has been removed.

[0702] In the cushion pad 350H of the seat cushion pad 302H, the rear side is formed of a low-hardness cushion material 3111 , and the front side is formed of a high-hardness cushion material 3112 .

[0703] The vibrating body 361 provided on the seat cushion 302H may be Fig.67 As shown in the vibrating body 361Ha, the vibrating body 361Ha is provided in the region of the low-hardness cushion member 3111. The low-hardness cushion member 3111 has a low density and is difficult to transmit vibrations, so it is possible to suppress the vibrations from being transmitted to other regions.

[0704] Moreover, it can also be like Fig.67 The vibrating body 361 is provided in the region of the high-hardness cushion material 3112 as in the vibrating body 361Hb shown in the figure. Vibration can be transmitted over a wide range.

[0705] <Positional Relationship between Vibrating Body 361 and Heater Device 380>

[0706] Fig.68A 302I is a schematic diagram of the seat cushion pad 302I showing the positional relationship between the heater device 380 and the vibrator 361 .

[0707] The seat cushion 302I has side support portions 3120 formed as banks that bulge toward the seat occupant on both sides thereof. The heating wire portion 381 of the heater device 380 is disposed on the seat surface 350a of the cushion 350I of the seat cushion 302I.

[0708] The vibrating body 361 is arranged outside the side of the heating wire portion 381 in the seat width direction. That is, the vibrating body 361 is arranged at a position that does not overlap with the heating wire portion 381 in a plan view.

[0709] The vibrating body 361 may be oriented toward Fig.68A The second vibrating body 3612 on the left side may be rotated in the direction of the arrow A and tilted. Fig.68A The device is configured to be rotated and tilted in the direction of arrow B.

[0710] By arranging in this way, the vibrator 361 can be kept away from the heater region (heating wire portion 381 ), and the mutual influence can be suppressed.

[0711] Fig.68B 1 is a schematic diagram of a seat cushion pad 302J showing another example of the positional relationship between the heater device 380 and the vibrator 361 .

[0712] and Fig.68A The seat cushion 302I shown in the figure is similar to the seat cushion 302J, and has side support portions 3120 that are bank portions that bulge toward the seat occupant side. Furthermore, the heating wire portion 381 of the heater device 380 is disposed on the seat surface 350a of the cushion 350J of the seat cushion 302I.

[0713] The vibrating body 361 of the seat cushion 302J is arranged on the inner side of the side portion of the heating wire portion 381 in the seat width direction. That is, the vibrating body 361 is arranged so that a part overlaps with the heating wire portion 381 in a plan view.

[0714] In this case, the vibrating body 361 may also be moved toward the first vibrating body 3611J located on the right side. Fig.68B The vibrating body 3612J may be rotated in the direction of the arrow A and tilted. Fig.68B The device is configured to be rotated and tilted in the direction of arrow B.

[0715] By arranging the vibrator 361 at an angle, the vibrator 361 can be separated from the heater region (heating wire portion 381 ), and the mutual influence can be suppressed.

[0716] <Positional Relationship between Vibrator 361 and Sensor Section>

[0717] Fig.69A 302K is a schematic diagram showing the positional relationship between the heater device 380 , the sensor device 370 , and the vibrator 361 .

[0718] and Fig.68A The seat cushion 302I shown in the figure is similar to the seat cushion 302K. On both sides of the seat cushion 302K, a bank portion, i.e., a side support portion 3120, is provided. Furthermore, a heating wire portion 381 of a heater device 380 is disposed on a seating surface 350a of a cushion 350K of the seat cushion 302K, and a sensor portion 371 of a sensor device 370 is disposed on both sides thereof. The sensor device 370 is a biological detection component, such as a pressure sensor for detecting a seating state, etc.

[0719] The vibrator 361 of the seat cushion 302K is arranged outside the side of the sensor portion 371 in the seat width direction. That is, the vibrator 361 is arranged at a position where a part does not overlap with the heater wire portion 381 and the sensor portion 371 in a plan view.

[0720] In this case, the vibrating body 361 may also be moved toward the first vibrating body 3611K located on the right side. Fig.69A The second vibrating body 3612K on the left side may be rotated in the direction of the arrow A and tilted. Fig.69B The device is configured to be rotated and tilted in the direction of arrow B.

[0721] By arranging the vibrator 361 at an angle, the vibrator 361 can be separated from the sensor region (sensor portion 371 ), and the mutual influence can be suppressed.

[0722] Fig.69B 1 is a schematic diagram of a seat cushion pad 302K showing another example of the positional relationship between the heater device 380 , the sensor device 370 , and the vibrator 361 .

[0723] and Fig.69A The seat cushion 302K shown in the figure is similarly provided with bank portions bulging toward the seat occupant side, i.e., side support portions 3120, on both sides of the seat cushion 302L. Furthermore, the heating wire portion 381 of the heater device 380 is arranged on the seat surface 350a of the cushion 350L of the seat cushion 302L, and the sensor portions 371 of the sensor device 370 are arranged on both sides thereof.

[0724] The vibrating body 361 of the seat cushion 302L is arranged inwardly in the seat width direction relative to the side portion of the sensor portion 371. That is, the vibrating body 361 is arranged at a position where a part thereof overlaps with the sensor portion 371 in a plan view.

[0725] In this case, the vibrating body 361 may also be moved toward the first vibrating body 3611L located on the right side. Fig.69B The second vibrating body 3612L on the left side may be rotated in the direction of the arrow A and tilted. Fig.69B The device is configured to be rotated and tilted in the direction of arrow B.

[0726] Even when the vibrator 361 and the sensor portion 371 overlap in a plan view, by arranging the vibrator 361 obliquely, the vibrator 361 can be moved away from the sensor region (sensor portion 371 ), thereby suppressing the mutual influence.

[0727] Figures 68A to 69B In the above description, the vibrating body 361 disposed on the seat cushion 302 is used as an example. However, the vibrating body 360 disposed on the seat back 301 may be disposed at an angle so as to be away from the heater device 380 or the sensor device 370. The mutual influence can be suppressed.

[0728] The vehicle seat S30 of the present embodiment is described above using the figures. In addition, in the present embodiment, the vehicle seat S30 is applicable to be carried in a vehicle, but the seat provided with the vibrating bodies 360 and 361 is not limited to the vehicle seat S30. It may also be a common chair or sofa, as long as it includes a seating surface. Furthermore, the configuration of the vibrating body 360 of the seat back 301 may be applied to the vibrating body 361 of the seat cushion 302, and the configuration of the vibrating body 361 of the seat cushion 302 may be applied to the vibrating body 360 of the seat back 301.

[0729] <<Fourth embodiment>>

[0730] A fourth embodiment of the present invention will be described below.

[0731] <<Technical Field>>

[0732] A fourth embodiment of the present invention relates to a vehicle seat, and more particularly to a vehicle seat including a vibrating body.

[0733] <<Background Technology>>

[0734] Conventionally, there is a known technique of configuring a vibrator on a seat back or seat cushion of a vehicle seat (see, for example, Japanese Patent Laid-Open No. 2000-225877). By vibrating the vibrator based on a signal obtained from a sensor, for example, the approach of another vehicle or obstacle can be notified to the occupant.

[0735] <<Disclosure of the Invention>>

[0736] <<Problems to be solved by the invention>>

[0737] However, in the prior art, sufficient consideration has not been given to the appropriate arrangement and structure of the relationship between the heater, the skin, or other components and the vibrator. In particular, a complicated structure is used to fix the vibrator.

[0738] Furthermore, as another problem, there is room for improvement in the functions of the vibrator itself, such as the performance of transmitting vibration to the occupant.

[0739] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a vehicle seat capable of making it easier to fix a vibrating body.

[0740] <<Technical means to solve the problem>>

[0741] The problem is solved by the following method, that is, according to the vehicle seat of the present invention, it includes a vibrator and a pad, the pad is formed with a recessed portion for configuring the vibrator, the vibrator is fixed by a covering member, the covering member at least covers the recessed portion and has functions other than fixing the vibrator in the recessed portion.

[0742] According to the vehicle seat, the vibrator is fixed by the covering member having a function other than fixing the vibrator in the recessed portion, so that the adhesive tape, cloth, plate material, etc., which are conventionally required for fixing the vibrator in the recessed portion, are no longer required, and the fixing of the vibrator can be made simpler. Furthermore, since the adhesive tape, etc., are no longer required, the number of parts can be reduced, and the manufacturing cost can be reduced.

[0743] Furthermore, in the above structure, the covering member may be a sheet-shaped heating element that heats the support surface.

[0744] By using a sheet-like heating element to fix the vibrator in the recess, the vibrator can be fixed in place without the need for adhesive tape or the like used to fix the vibrator, thereby simplifying the fixing of the vibrator. Furthermore, since the vibrator can no longer be fixed with adhesive tape or the like, the number of parts can be reduced, thereby reducing manufacturing costs.

[0745] Furthermore, in the above configuration, the heat generating element may be fixed to the pad via a fixing portion provided on the back surface of the heat generating element, and the fixing portion may be arranged at a position overlapping with the vibrator.

[0746] By arranging the fixing portion for fixing the heat generating body at a position overlapping with the vibrating body, it is possible to increase the fixing force for fixing the vibrating body.

[0747] Furthermore, in the above configuration, the heat generating element may be fixed to the pad via a fixing portion provided on the back surface of the heat generating element, and the fixing portion may be arranged at a position that does not overlap with the vibrator.

[0748] By arranging the fixing portion for fixing the heating element at a position that does not overlap with the vibrating body, the influence of the vibrating body on the heater can be reduced.

[0749] Furthermore, in the above configuration, the heat generating element may be configured so that a temperature of a region overlapping with the vibrator is different from a temperature of a region not overlapping with the vibrator.

[0750] Sometimes the vibrating body absorbs the heat of the heating body, or the vibrating body itself generates heat and increases the heat. By making the temperature of the area overlapping with the vibrating body different from the temperature of the area not overlapping, the difference caused by the absorption or generation of heat by the vibrating body is eliminated, for example, the heat transferred to the occupant can be adjusted to be uniform over the entire area of ​​the heating body without causing discomfort.

[0751] Furthermore, in the above configuration, the heating element may include a heating wire, and the vibrating body overlapping the heating wire may be arranged so that the longitudinal direction of the vibrating body intersects the extending direction of the heating wire at a substantially right angle.

[0752] By arranging the vibrator to intersect at right angles with the extending direction of the heating wire, the occupant is less likely to feel uncomfortable and vibration can be applied in a natural state.

[0753] Furthermore, in the above structure, the heating element may include a heating wire, and the vibrating body overlapping the heating wire may be arranged so that the long side direction of the vibrating body and the extending direction of the heating wire obliquely intersect at an acute angle or an obtuse angle.

[0754] By configuring the vibrator to cross the extension direction of the heating wire at an acute angle or an obtuse angle, the vector of the overload applied to the heating wire by the vibrator is laterally deviated, thereby reducing the influence on the heating wire (such as cutting due to vibration).

[0755] Furthermore, in the above structure, the covering member may be a skin having a protective function of the pad, and the skin may be fixed to the pad by hook and loop fasteners, and the hook and loop fasteners may be arranged at a position overlapping with at least a portion of the vibrator.

[0756] By fixing the vibrator to the recessed portion using a protective cover, the fixing of the vibrator can be simplified. Furthermore, no tape or the like is required to fix the vibrator, and the number of parts can be reduced. Furthermore, by arranging the hook-and-loop fastener so as to overlap a portion of the vibrator, the performance of the vibrator is less likely to be impeded.

[0757] Furthermore, in the above structure, the covering member may be a skin having a protective function of the pad, the skin being fixed to the pad by hook and loop fasteners, and the hook and loop fasteners being arranged at a position not overlapping the vibrator.

[0758] By fixing the vibrator to the recessed portion using a protective cover, the fixing of the vibrator can be simplified. Furthermore, no tape or the like is required to fix the vibrator, and the number of parts can be reduced. Furthermore, by configuring the hook-and-loop fastener so as not to overlap the vibrator, the performance of the vibrator is less likely to be hindered.

[0759] Moreover, in the structure, the covering member may be a skin having a protective function of the pad, the skin is fixed to the pad by an embedding portion, and a embedding groove for inserting the embedding portion is formed in the pad, and the vibrator is arranged in the embedding groove.

[0760] By fixing the vibrator to the hanging groove using a protective cover, the fixing of the vibrator can be simplified. Moreover, the hanging groove and the vibrator can be taken into consideration, and the influence on the appearance of the cover can be suppressed.

[0761] Furthermore, in the above structure, the hanging member may be arranged at a position away from the vibrating body.

[0762] By arranging the hanging member at a position away from the vibrator, it is possible to achieve a balance between the hanging groove and the vibrator, and to suppress the influence on the appearance of the surface.

[0763] Furthermore, in the above configuration, the vibrator may be provided with a directivity adjustment unit for directing the vibration of the vibrator in a predetermined direction.

[0764] By providing the directivity adjustment section in the vibrator, the vibration can be transmitted to the occupant more efficiently.

[0765] Furthermore, in the above configuration, the directivity adjusting section may be a plate-shaped member disposed on a surface of the vibrating body on the passenger side.

[0766] By providing the directivity adjuster as a plate-shaped member, the directivity adjuster can be easily provided on the vibrator.

[0767] Furthermore, in the above configuration, the directivity adjusting portion may be a wall portion on the seat surface side formed thicker than other wall portions in the housing of the vibrator.

[0768] By forming the wall portion on the passenger side of the housing of the vibrator to be thick to provide the directivity adjusting portion, the directivity adjusting portion can be provided without increasing the number of components.

[0769] <<Effects of the Invention>>

[0770] According to the vehicle seat of the fourth embodiment of the present invention, the vibrator is fixed by a covering member having a function other than the function of fixing the vibrator in the recessed portion, so that the adhesive tape, cloth, plate material, etc., which are conventionally required for fixing the vibrator in the recessed portion, are no longer required, and the fixing of the vibrator can be made simpler. Furthermore, since the adhesive tape, etc., are no longer required, the number of parts can be reduced, thereby reducing the manufacturing cost.

[0771] Furthermore, by using a sheet-like heating element to fix the vibrator in the recess, the vibrator can be fixed more easily by eliminating the need for adhesive tape or the like used to fix the vibrator.

For example, the heat transferred to the occupant can be adjusted to be uniform over the entire area of ​​the heating body without causing discomfort.

[0775] Furthermore, by arranging the vibrator to intersect at right angles with the extending direction of the heating wire, the occupant is less likely to feel uncomfortable and vibration can be applied in a natural state.

[0776] Moreover, by configuring the vibrator to cross the extension direction of the heating wire at an acute angle or an obtuse angle, the vector of the overload applied to the heating wire by the vibrator is laterally deviated, thereby reducing the impact on the heating wire (such as cutting caused by vibration).

[0777] Furthermore, by fixing the vibrator to the recessed portion using the cover having a protective function, the fixing of the vibrator can be simplified. Furthermore, no tape or the like is required to fix the vibrator, and the number of parts can be reduced. Furthermore, by arranging the hook-and-loop fastener so as to overlap with a portion of the vibrator, the performance of the vibrator is less likely to be impeded.

[0778] Furthermore, by fixing the vibrator to the recessed portion using the protective cover, the fixing of the vibrator can be simplified. Furthermore, no tape or the like is required to fix the vibrator, and the number of parts can be reduced. Furthermore, by configuring the hook-and-loop fastener so as not to overlap the vibrator, the performance of the vibrator is less likely to be hindered.

[0779] Furthermore, by fixing the vibrator to the hanging groove using the protective cover, the fixing of the vibrator can be simplified. Furthermore, the hanging groove and the vibrator can be taken into consideration at the same time, and the influence on the appearance of the cover can be suppressed.

[0780] Furthermore, by arranging the hanging member at a position away from the vibrator, it is possible to achieve a balance between the hanging groove and the vibrator, and to suppress the influence on the appearance of the surface.

[0781] Furthermore, by providing the directivity adjustment section in the vibrator, the vibration can be transmitted to the occupant more efficiently.

[0799] like Fig.71 As shown, the seat back frame 410 is formed in a frame shape as a whole, and includes a pair of back side frames 411, 411 arranged on the left and right, an upper frame 412 and a bottom frame 413. The upper frame 412 is provided with a pair of headrest brackets 414 through which the headrest posts 431 of the headrest 403 are inserted.

[0801] The seat cushion frame 420 includes a front connecting frame (not shown) that connects a pair of cushion side frames 421, 421 at the front side and a rear connecting frame 422 that connects a pair of cushion side frames 421, 421 at the rear side. A plate-shaped base frame is provided in front of the front connecting frame. The seat cushion frame 420 includes a cushion pressure member 425 that is arranged to bridge the front connecting frame and the rear connecting frame 422. The cushion pressure member 425 can support the buttocks of the seated person from below.

[0802] As described above, the headrest frame 430 is a member constituting the framework of the headrest 403. The headrest frame 430 is formed in an inverted U shape in front view, and can be attached to the upper end of the seat back 401 by inserting the headrest pillar 431 extending downward into the headrest bracket 414.

[0803] <Mat P40>

[0804] use Fig.71 The pad P40 includes a back pad 440 mounted on the seat back frame 410, a cushion pad 450 mounted on the seat cushion frame 420, and a headrest pad 432 mounted on the headrest frame 430. The pad P40 includes, for example, a urethane base material formed by foaming using a urethane foam material.

[0805] Furthermore, the back pad 440, the cushion pad 450, and the headrest pad 432 are respectively covered with a cover 406. The cover 406 includes, for example, fabric, synthetic leather, or genuine leather.

[0806] <Back pad 440>

[0807] The back pad 440 includes a main body 441 for supporting the back of the occupant and a bank 442 for supporting the back from the side. Fig.71 and Fig.72 As shown, two vertical hanging grooves 443 extending in the up-down direction and a horizontal hanging groove 444 extending in the seat width direction are formed. The vertical hanging groove 443 is formed at the boundary portion between the main body 441 and the bank 442. Moreover, the horizontal hanging groove 444 connects the upper end portions of the two vertical hanging grooves 443.

[0808] Furthermore, a through hole 447 is formed in a part of the vertically embedded hanging groove 443 along the vertically embedded hanging groove 443. By forming the through hole 447, the deformation of the back pad 440 becomes easy. Furthermore, the through hole 447 is arranged at a position overlapping with the vibrating body 460 described later in the vertical direction, and the deformation caused by the vibrating body 460 can be absorbed through the through hole 447.

[0809] <Cushion pad 450>

[0810] The cushion pad 450 includes a main body 451 for supporting the buttocks of the occupant and a bank 452 for supporting the buttocks from the side. Fig.73 As shown, a longitudinal insertion hanging groove 453 extending in the front-rear direction and a transverse insertion hanging groove 454 extending in the seat width direction are formed in the cushion pad 450. The longitudinal insertion hanging groove 453 is arranged between the main body 441 and the bank 452. Moreover, the transverse insertion hanging groove 444 connects the two longitudinal insertion hanging grooves 453, 453.

[0811] <Vibrating body 460>

[0812] The vibrator 460 is a device for vibrating the seated occupant. Fig.71 As shown, two vibrators 460 are provided in the back pad 440. Furthermore, two vibrators 460 are also provided in the cushion pad 450. The vibrators 460 provided in the back pad 440 and the vibrators 460 arranged in the cushion pad 450 have the same mechanism.

[0813] in addition, Figure 71 to Figure 73 The position and number of the vibrating body 460 shown are merely examples, and the vibrating body 460 provided on the back pad 440 or the cushion pad 450 may be one, or two or more vibrating bodies 460 may be provided on the back pad 440 or the cushion pad 450 .

[0814] The vibrating body 460 includes a housing 461 and an eccentric motor 462 (see Fig.84 ). In addition, a linear vibration actuator or a piezoelectric element is used to generate vibration of the vibrating body 460. Moreover, a wire harness 463 extends from the eccentric motor 462 of the vibrating body 460 and is connected to an ECU (not shown) mounted in the vehicle. The ECU can control the intensity of the vibration of the vibrating body 460 or the timing of the vibration.

[0815] <Storage recess 445>

[0816] like Fig.71 As shown, a receiving recess 445 for receiving the vibrator 460 on the back side is formed on the seating surface 440a of the back pad 440. By inserting the vibrator 460 into the receiving recess 445, the vibrator 460 can be mounted.

[0817] Moreover, if Fig.71 As shown, a receiving recess 455 for receiving the vibration body 460 on the cushion pad side is also formed on the seating surface 450a of the cushion pad 450. By inserting the vibration body 460 into the receiving recess 455, the vibration body 460 can be attached.

[0818] Moreover, if Fig.75 As shown, the bottom surfaces of the storage recesses 445 and 455 are provided with harness holes 446 and 456 for passing the harness 463 extending from the vibrator 460 , so that the harness 463 can be introduced to the back surface of the back pad 440 or the bottom surface of the cushion pad 450 .

[0819] In addition, the harness holes 446 and 456 are not limited to the bottom surface, and may be formed in the side walls of the storage recesses 445 and 455. In this case, for example, the harness holes 446 and 456 are formed such that the harness 463 is passed from the side walls of the storage recesses 445 and 455 to the horizontal insertion and hanging grooves 444 and 454, and is passed from the bottom of the horizontal insertion and hanging grooves 444 and 454 to the back surface of the back pad 440 or the bottom surface of the cushion pad 450. Furthermore, the harness 463 may be introduced to the back surface of the back pad 440 or the bottom surface of the cushion pad 450 by using the holes for hanging formed in the horizontal insertion and hanging grooves 444 and 454.

[0820] <Heater 470>

[0821] like Fig.71 As shown, a sheet-like heater 470 is disposed on the seating surfaces 440 a and 450 a of the main bodies 441 and 451 of the back pad 440 and the cushion pad 450 .

[0822] The heater 470 is a sheet-like base fabric 472 in which a heating wire 471 (electric heating wire) is disposed in a meandering manner, and is provided with flexibility and arranged along the seat surfaces 440a, 440a. The base fabric 472 is made of, for example, nonwoven fabric.

[0823] The heating wire 471 includes a material (eg, a metal wire or film) that generates heat when an electric current flows therethrough. Both ends of the heating wire 471 are connected to an ECU (not shown), so that the temperature of the heating wire 471 can be adjusted by the ECU.

[0824] <Fixing structure of vibrating body 460>

[0825] Below, while referring to Figure 74 to Figure 7 , while explaining the fixing structure of the vibrator 460 arranged in the back pad 440 and the cushion pad 450. Fig.74 is a cross-sectional view schematically showing a fixing structure of a conventional vibrating body 4160. Fig.75 and Fig.76 is a diagram showing a fixing structure of the vibrating body 460 of this embodiment, and is a diagram showing a fixing structure of the vibrating body 460 of this embodiment. Fig.72 AA line or Fig.73 The cross-sectional diagram of the BB line. In addition, Figure 74 to Figure 76 , the arrow X direction indicates the passenger side, that is, the direction in which the seating surfaces 440a, 450a of the back pad 440 or the cushion 450 are located, and the arrow Y direction indicates the opposite side of the passenger, that is, the direction in which the back surface of the back pad 440 or the cushion 450 is located.

[0826] In the past, Fig.74 As shown, after the vibrator 4160 is inserted into the storage recess 4145, the tape 4108 is attached to the periphery of the opening of the storage recess 4145, thereby fixing the vibrator 4160 to the pad P40. Then, the cover 4106 is attached in a state where the vibrator 4160 is fixed to the pad P40.

[0827] The vehicle seat S40 of this embodiment is configured with a sheet-like heater 470 instead of the tape after the vibrator 460 is inserted into the storage recess 445, and the heater 470 is fixed to the back pad 440 or the cushion pad 450, thereby fixing the vibrator 460 to the storage recess 445. The heater 470 is attached to the back pad 440 or the cushion pad 450 by an adhesive material 473 (fixing portion) such as a double-sided tape. The vibrator 460 is fixed to the storage recess 445 by the attached heater 470. That is, the vibrator 460 is fixed by the sheet-like heater 470 having a function other than the function of fixing the vibrator 460 to the storage recess 445 (the function of heating the support surface).

[0828] Since there is no need for Fig.74 The vibrator 460 can be fixed more easily than the conventional fixing structure shown in the figure, which does not require the adhesive tape to be attached to the periphery of the storage recess. In addition, since the adhesive tape conventionally used to fix the vibrator is no longer required, the number of parts can be reduced, thereby reducing the manufacturing cost.

[0829] In addition, the bonding area R of the bonding material 473 may also be Fig.75 The heater 470 may overlap with the vibrating body 460 as shown in the figure. That is, when viewed from the passenger side, the adhesive region R for attaching the heater 470 to the back pad 440 or the cushion pad 450 may also overlap with the vibrating body 460. In other words, the adhesive material 473 (fixing portion) may also be arranged between the vibrating body 460 and the heater 470. By overlapping the adhesive region R with the vibrating body 460, the fixing force of the heater 470 to the vibrating body 460 is improved.

[0830] Furthermore, the bonding area R of the bonding material 473 may also be Fig.76 That is, the vibrator 460 may be arranged so that the adhesion region R does not overlap with the vibrator 460 when viewed from the passenger side. Since the vibrator 460 is not adhered to the heater 470, the influence of the vibration of the vibrator 460 on the heater 470 (such as the cutting of the heating wire 471) is reduced.

[0831] Depending on the material or type of the vibrator 460, the vibrator 460 may deprive the heater 470 of heat due to the contact between the vibrator 460 and the heater 470, that is, the vibrator 460 absorbs the heat from the heater 470. In addition, the vibrator 460 itself may generate heat due to vibration, thereby heating the heater 470. Therefore, the temperature transmitted to the occupant may differ depending on the part.

[0832] Therefore, in the structure in which the heater 470 is arranged on the vibrating body 460, the region Q1 (see Fig.75 ) is set to a temperature that is hotter or lower than a temperature in a region Q2 that does not overlap with the vibrating body 460. That is, by adjusting the amount of heat generated by the heater 470, the temperature transmitted to the occupant becomes uniform over the entire range of the heater 470.

[0833] As a method of increasing the heating temperature only in the area overlapping with the vibrating body 460, there are the following methods. One is to arrange the heating wires 471 in the area Q1 overlapping with the vibrating body 460 more densely than in other areas Q2 that do not overlap. That is, the interval between the heating wires 471 is reduced to increase the heat generation per unit area, thereby making the heating temperature higher than that in other areas Q2 that do not overlap.

[0834] Furthermore, the systems of the heating wires 471 in the overlapping region Q1 and the non-overlapping region Q2 may be set as independent systems. That is, the heating wires 471 arranged in the overlapping region Q1 and the heating wires 471 arranged in the non-overlapping region Q2 are independently controlled, and the wattage of the power flowing to the heating wires 471 in the overlapping region Q1 is set high.

[0835] By controlling the heater 470 so that heat is generated at a high temperature only in the overlapping region Q1 in consideration of the fact that heat is deprived by the vibrator 460 , the entire region can be set to a uniform temperature.

[0836] Furthermore, as a method of lowering the heat generation temperature in the region Q1 overlapping with the vibrating body 460 , there is the following method.

[0837] One is to arrange the heating wires 471 more sparsely in the region Q1 overlapping with the vibrating body 460 than in the other regions Q2 not overlapping with the vibrating body 460. That is, the intervals between the heating wires 471 turning back are increased to reduce the heat generation per unit area, thereby setting the heating temperature lower than that in the other regions Q2 not overlapping with the vibrating body 460.

[0838] Moreover, similarly to the case of increasing the temperature, the heating wire systems in the overlapping region Q1 and the non-overlapping region Q2 may be set as independent systems. That is, the heating wire 471 disposed in the overlapping region Q1 and the heating wire 471 disposed in the non-overlapping region Q2 are independently controlled, thereby setting the wattage of the power flowing to the heating wire 471 low only in the overlapping region Q1 to make it a low temperature.

[0839] By controlling the temperature to be low only in the overlapping region Q1 in consideration of the heat generated by the vibrator 460 , the temperature of the entire region of the heater 470 can be uniformly heated.

[0840] Furthermore, a heat absorbing member such as a cloth that absorbs heat may be disposed between the vibrator 460 and the heater 470 so that the temperature becomes low only in the overlapping region Q1 .

[0841] Next, use Fig.72 , Fig.73 , Fig.77A and Fig.77B The positional relationship of the vibrator 460 with respect to the heating wire 471 will be described.

[0842] As described above, the heating wires 471 meander on the base fabric 472 and are arranged in parallel at equal intervals except for the curved portions.

[0843] In this embodiment, if Fig.72 and Fig.73 As shown, the vibrating body 460 is arranged such that the long side direction ( Fig.72 Up and down direction or Fig.73 The front-to-rear direction) is relative to the extending direction of the heating wire 471 (the seat width direction, Fig.72 and Fig.73 By configuring in this way, it is possible to set it to a more natural state for the occupant, that is, a state in which it is difficult to feel uncomfortable.

[0844] Moreover, it is also possible to Fig.77A As shown, the vibrating body 460 is arranged so that its long side direction (the direction of arrow I in FIG. 77 ) is opposite to the extending direction of the heating wire 471 ( Fig.77A The crossing angle α is an acute angle or an obtuse angle, whereby the vector of the overload (boundary portion) applied to the heating wire 471 and the vibrating body 460 deviates laterally, which can reduce the influence on the heating wire 471, such as cutting due to vibration.

[0845] Moreover, it is also possible to Fig.77B As shown, the vibrator 460 is arranged so as to overlap with the bent portion 471 a of the heating wire 471 .

[0846] <<Second embodiment>>

[0847] Next, use Figure 78A to Figure 79 A second example of this embodiment will be described. Figure 78A to Figure 78C 1 is a front view showing a back pad 440A of a vehicle seat SA40 as a second embodiment, and is a view showing the position of a hook and loop fastener 480 overlapping with a vibrating body. Fig.79 It is a cross-sectional view taken along line CC of FIG. 78 , and is a view showing the positional relationship between the hook and loop fastener 480 and the vibrator 460 .

[0848] In the vehicle seat S40 of the first embodiment, a sheet-shaped heater 470 is used to fix the vibrating body 460, but in the vehicle seat SA40 of the second embodiment, the main difference is that a skin 406 (covering member) having a protective function of a pad P40 is used to fix the vibrating body 460. Figure 70 to Figure 71 Components having the same or equivalent structures shown in the figures are given the same reference numerals, and their description is omitted.

[0849] The vehicle seat SA40 of the second embodiment includes a vibrating body 460 and a back pad 440 having a storage recess 445 for arranging the vibrating body 460. The vibrating body 460 is arranged at a position overlapping the vibrating body 460 and fixed by a cover 406 having a protective function of the pad P40.

[0850] like Fig.79 As shown, the cover 406 is secured to the back pad 440 (pad P40) by hook and loop fasteners 4080 mounted on the back of the cover 406.

[0851] If we elaborate further, Fig.79As shown, a skin-side fastener member 481 is installed on the back of the skin 406 as a hook portion of the hook-and-loop fastener 480, and a pad-side fastener member 482 is installed on the surface of the back pad 440A as a loop portion of the hook-and-loop fastener 480. The skin-side fastener member 481 and the pad-side fastener member 482 are fixed to the skin 406 and the back pad 440 by well-known fixing members such as adhesives or clips. The skin 406 can be detachably fixed to the back pad 440 by the hook-and-loop fastener 480.

[0852] like Fig.78A As shown, the hook-and-loop fastener 480 is arranged at a position overlapping with a part of the vibrating body 460. In other words, the vibrating body 460 is arranged so as to be located further back than the hook-and-loop fastener 480 when viewed from the passenger side. By overlapping the hook-and-loop fastener 480 with a part of the vibrating body 460, it is possible to suppress the hindrance to the performance of the vibrating body 460 and to implement fixation.

[0853] By fixing the cover 406 to the back pad 440 using the hook and loop fastener 480 in this way, the vibrator 460 can be fixed to the storage recess 445 without using a conventional tape or the like for fixing the vibrator 460. In addition, the hook and loop fastener 480 and the vibrator 460 can be both taken into consideration.

[0854] Fig.78A The hook and loop fastener 480 shown is fixed to the storage recess 445 by overlapping a portion of the vibrating body 460, but it can also be as shown in FIG. Fig.78B As shown, the hook-and-loop fastener 480 is arranged so as to cover the entire vibrator 460. By covering the entire vibrator 460 with the hook-and-loop fastener 480, it is possible to suppress the influence on the appearance, such as the expansion of the surface and the generation of wrinkles.

[0855] Moreover, it is also possible to Fig.78C As shown, the hook and loop fastener 480 does not directly overlap the vibrator 460. By arranging the hook and loop fastener 480 so as to sandwich the vibrator 460, the performance of the vibrator 460 is less likely to be hindered.

[0856] in addition, Figure 78A to Figure 78C 4 shows a hook-and-loop fastener 480 for fixing the skin 406 to the back pad 440, but the hook-and-loop fastener 480 may be used to fix the skin 406 to the cushion pad 450. The hook-and-loop fastener 480 may be arranged at a position overlapping with a part of the vibrating body 460 provided in the cushion pad 450, and the hook-and-loop fastener 480 may be arranged to cover the entire vibrating body 460 provided in the cushion pad 450. The hook-and-loop fastener 480 may also be arranged to sandwich the vibrating body 460 provided in the cushion pad 450.

[0857] <Arrangement for vertical insertion into the hanging groove 443>

[0858] The vibrating body 460 may also be Fig.80 As shown, it is configured in the longitudinal embedding groove 443 for embedding the surface skin 406.

[0859] By arranging the vibrator 460 in the vertical insertion hanging groove 443, the vertical insertion hanging groove 443 can be used instead of the housing recess 445 for housing the vibrator 460. Thus, for example, the influence on the appearance of the cover 406 can be suppressed.

[0860] In addition, the width W1 of the vibrating body 460 is larger than the width W2 of the conventional vertically embedded hanging groove 443. Fig.81 As shown, the width W3 of the vertical insertion hanging groove 443 at the portion where the vibrating body 460 is arranged is formed to be wider than the width W2 of the other portion.

[0861] Furthermore, since the height D1 of the vibrating body 460 is also larger than the depth D2 of the normal vertically inserted hanging groove 443 , the depth D3 of the portion where the vibrating body 460 is arranged is formed larger than the depth D2 of the other portions.

[0862] Moreover, if Fig.82 As shown, a hanging portion 490 for hanging is provided on the back of the skin 406, and the skin 406 is fixed by the hanging portion 490 being engaged with a linear member such as a C-shaped ring or a clamping member (engaging portion) inserted and molded in the pad.

[0863] In addition, when the vibrating body 460 is disposed in the vertical insertion groove 443, the insertion portion 490 interferes with the vibrating body 460. Fig.82 As shown in the figure, the hanging part 490 is formed with an escape portion 491 at a portion overlapping with the vibrating body 460, so that when the skin 406 is hung, interference between the vibrating body 460 and the hanging part 490 can be avoided.

[0864] Fig.81 and Fig.82 In the back pad 440A shown, the vibrator 460 is arranged in the vertically embedded hanging groove 443, but the vibrator 460 may also be arranged in the horizontally embedded hanging groove 444. Moreover, the same structure may also be applied to the cushion pad 450. That is, the vibrator 460 may also be arranged in the vertically embedded hanging groove 453 or the horizontally embedded hanging groove 454 of the cushion pad 450.

[0865] Moreover, it can also be like Fig.83 As shown in the back pad 440A, the vibrating body 460 ( Fig.83 When the vibrating body 460 is arranged in the longitudinal embedded hanging groove 443, the longitudinal embedded hanging groove 443 is formed in a curved manner to avoid the vibrating body 460.

[0866] That is, an island portion 449 for arranging the vibrator 460 is provided adjacent to the bank portion 442, and a curved portion 448 for vertically fitting the hanging groove 443 is formed to avoid the island portion 449. The vibrator 460 is arranged in the storage recess provided in the island portion 449. Thus, the vertically fitting hanging groove 443 and the vibrator 460 can be taken into consideration, and the influence on the appearance of the skin 406 can be suppressed.

[0867] You can also Fig.83 As shown, the longitudinally embedded hanging groove 443 is arranged in a manner avoiding the island portion 449 toward the inner side of the seat. In addition, the longitudinally embedded hanging groove 443 may also be arranged in a manner avoiding the island portion 449 toward the outer side of the seat.

[0868] A skin fixing point 492 for fixing the skin 406 may be arranged in the curved portion 448 of the vertical insertion hanging groove 443 avoiding the island portion 449. In the curved portion 448, it is possible to suppress the skin 406 from floating.

[0869] The skin fixing point 492 is, for example, a wire member or a clamping member such as a C-shaped ring that is insert-molded into the pad.

[0870] Furthermore, the hanging portion 490 of the skin 406 may be provided with an escape portion 491 in the portion from the starting point 448a to the end point 448b of the curved portion 448 of the vertical hanging groove 443. By forming the escape portion 491, the hanging of the skin 406 becomes easy.

[0871] <Directivity adjustment unit 465>

[0872] The eccentric motor built into the conventional vibrator generates centrifugal force in all directions to vibrate, so the vibration has no directionality and vibrates in directions that do not need to be transmitted. However, since the vibrator 460 used in this embodiment is fixed to the seat back 401 or the seat cushion 402, the vibration direction to be transmitted is limited to the passenger side. Therefore, it is more efficient if the vibration can be directed toward the passenger.

[0873] The vibrating body 460 used in this embodiment is a vibrating body provided with an eccentric motor 462 in a housing 461. In the housing 461, an eccentric motor 462 is provided on a surface ( Fig.80 The directivity adjustment unit 465 is provided on the surface of the housing 461 that is located in the X direction. The directivity adjustment unit 465 is a plate member made of resin that is formed independently from the housing 461.

[0874] By providing the directivity adjustment unit 465 on the surface on the passenger side, when the eccentric motor 462 rotates, the directivity adjustment unit 465 moves toward the passenger in a predetermined direction ( Fig.84 The vibration direction is thus directed toward the passenger side.

[0875] The directivity adjusting section 465 is preferably a resin plate member formed independently, but the directivity adjusting section 465 may be a metal plate member.

[0876] Furthermore, it is desirable that the directivity adjustment unit 465 and the surface 461a on the passenger side of the housing 461 are of the same size, but the directivity adjustment unit 465 may be larger than the surface 461a on the passenger side of the housing 461, or may be smaller than the surface 461a on the passenger side of the housing 461. By setting the directivity adjustment unit 465 to be of the same size as the surface 461a on the passenger side of the housing 461, a balance between the intensity of vibration and the configuration properties can be achieved.

[0877] The directivity adjustment unit 465 is fixed to the housing 461 by an adhesive member such as a double-sided tape on the passenger-side surface 461c of the housing 461. The directivity adjustment unit 465 may be engaged and fixed to the housing 461 by an engagement member such as a screw.

[0878] Another example (vibrator 460A) of the vibrator 460 having the directivity adjustment portion 465 is shown in FIG. Fig.85 The directivity adjustment part 465A of the vibrating body 460A is realized by forming the wall part 461Aa disposed on the passenger side of the housing 461A thicker than the other wall parts 461Ab to form a thick wall part. That is, the directivity adjustment part 465 is formed in a manner integral with the housing 461A.

[0879] By forming a part of the housing 461 thickly and integrally forming it with the directivity adjusting section 465A, the number of parts can be reduced compared to when the directivity adjusting section 465 is formed independently.

[0880] The above is a description of the vehicle seat of the present embodiment using the figures. In addition, in the present embodiment, the vehicle seat is suitable for being mounted in a vehicle, but the seat provided with a vibrating body is not limited to the vehicle seat. The seat provided with a vibrating body may also be a common chair or sofa, as long as it includes a seating surface.
