Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above prior art, the portions of the left and right lumber wires where the blower mounting brackets are attached are bent in a substantially crank shape, and the displacement of the blower mounting brackets to the rear side of the seat by the lumber wires is suppressed. Therefore, when a vehicle rear-end collision occurs, it is difficult for the back of the seated person to sink into the seat back. As a result, the timing at which the head of the seated person is supported by the headrest is delayed, and there is room for improvement from the viewpoint of preventing whiplash injury to the seated person.

[0005] An object of the present invention is to obtain a blower mounting structure for a seat back and a vehicle seat that make it easy for the back of a seated person to sink into the seat back during a vehicle rear-end collision.

Means for Solving the Problems

[0006] The seat back fan mounting structure of the first embodiment comprises left and right lumbar wires stretched between the upper and lower parts of the seat back frame of a vehicle seat, a lumbar support mechanism attached to the left and right lumbar wires, a mounting bracket positioned above the seat relative to the lumbar support mechanism, a fan attached to the rear side of the mounting bracket, and mounting wires extending from the upper end of the lumbar support mechanism and having left and right mounting portions to which the left and right sides of the mounting bracket are attached, wherein the left and right mounting portions deform when a load is applied to the mounting bracket from the front side of the seat.

[0007] According to the first embodiment, left and right lumbar wires are stretched between the upper and lower parts of the seat back frame of a vehicle seat, and a lumbar support mechanism is attached to the left and right lumbar wires. A mounting bracket is positioned on the seat-up side relative to the lumbar support mechanism, and a blower is attached to the rear-facing surface of the mounting bracket. Left and right mounting portions of the mounting wires extend from the upper end of the lumbar support mechanism, and the left and right sides of the mounting bracket are attached to these left and right mounting portions. When a load from the seated person's back is applied to the mounting bracket from the front of the seat during a rear-end collision of the vehicle, the left and right mounting portions of the mounting wires deform. This makes it easier for the seated person's back to slide into the seat back.

[0008] The blower mounting structure for the seat back in the second embodiment, in the first embodiment, has a mounting portion comprising: a first longitudinal extension extending upward from the upper end of the lumbar support mechanism to the seat; a first transverse extension extending outward in the left-right direction from the upper end of the first longitudinal extension; a second longitudinal extension extending downward from the left-right outer end of the first transverse extension to the seat; and a second transverse extension extending inward in the left-right direction from the lower end of the second longitudinal extension and connecting to the upper end of the lumbar support mechanism; and the side portion comprising: a first locking claw engaged with the first longitudinal extension; and a second locking claw engaged with the first transverse extension.

[0009] According to the second embodiment, from the upper end of the lumbar support mechanism, first longitudinal extensions of the left and right mounting parts of the mounting wire extend upward toward the seat, from the upper end of the first longitudinal extension, a first transverse extension extends outward toward the left and right of the seat, from the outer end of the first transverse extension toward the left and right of the seat, a second longitudinal extension extends downward toward the seat, from the lower end of the second longitudinal extension, a second transverse extension extends inward toward the left and right of the seat, and the second transverse extension is connected to the upper end of the lumbar support mechanism. A first locking claw provided on the side of the mounting bracket is locked to the first longitudinal extension of the mounting part, and a second locking claw provided on the side of the mounting bracket is locked to the first transverse extension of the mounting part. When a load is applied to the mounting bracket from the front of the seat, the mounting bracket is allowed to flex toward the rear of the seat between the first longitudinal extensions of the left and right mounting parts. This makes it easier for the seated person's back to slide further into the seat back.

[0010] In the third embodiment of the seat back fan mounting structure, in the second embodiment, the mounting bracket is elastically deformed by the load from the back of the seated person during normal use.

[0011] According to the third embodiment, the mounting bracket undergoes elastic deformation due to the load from the seated person's back during normal use. This improves the seating comfort for the person sitting.

[0012] In the fourth embodiment, the seatback fan mounting structure, in the second or third embodiment, the mounting bracket is plastically deformed by the load from the seated person's back during a rear-end collision.

[0013] According to the fourth embodiment, the mounting bracket undergoes plastic deformation due to the load from the occupant's back during a rear-end collision. This allows the occupant's energy to be absorbed, thereby suppressing the rebound of the occupant, whose back is tucked into the seatback, towards the front of the seat.

[0014] The seat back fan mounting structure of the fifth embodiment is such that, in any one of the first to fourth embodiments, the left and right mounting portions are elastically deformed by the load from the back of the seated person during normal use.

[0015] According to the fifth embodiment, the left and right mounting portions of the mounting wire are elastically deformed by the load from the back of the seated person during normal use. This improves the seating comfort of the person sitting.

[0016] The seatback fan mounting structure of the sixth embodiment is such that, in any one of the first to fifth embodiments, the left and right mounting portions are plastically deformed by the load from the seated person's back during a rear-end collision.

[0017] According to the sixth embodiment, the left and right mounting portions of the mounting wire undergo plastic deformation due to the load from the occupant's back during a rear-end collision. This allows the occupant's energy to be absorbed, thereby suppressing the rebound of the occupant, whose back is tucked into the seatback, towards the front of the seat.

[0018] The seventh embodiment of the vehicle seat comprises a seat cushion on which a sitter sits, and a seat back that supports the sitter's back, wherein the seat back has a fan mounting structure of any one of the first to sixth embodiments of the seat back.

[0019] In the seventh embodiment of the vehicle seat, the back of the occupant sitting on the seat cushion is supported by the seat back. Since this seat back has the fan mounting structure of any one of the first to sixth embodiments of the seat back, the aforementioned effects can be obtained. [Effects of the Invention]

[0020] As described above, according to the present invention, the back of the occupant becomes more easily tucked into the seat back during a rear-end collision. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0022] Hereinafter, a vehicle seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 10. In each figure, some reference numerals may be omitted for ease of viewing the drawings. Also, the arrows FR, LH, RH, and UP appropriately shown in each figure indicate the front, left, right, and upper directions of the vehicle seat 10, respectively. Hereinafter, when simply explaining using the front-rear, left-right, and up-down directions, it shall indicate the direction with respect to the vehicle seat 10.

[0023] As shown in Figure 1, the vehicle seat 10 according to this embodiment is, for example, a front seat of a vehicle and comprises a seat cushion 12 on which the occupant sits, a seat back 14 that supports the occupant's back, and a headrest 16 that supports the occupant's head. The seat cushion 12 is connected to the floor of the vehicle via a well-known sliding mechanism 18. The lower end of the seat back 14 is connected to the rear end of the seat cushion 12 via a well-known reclining mechanism 20. The headrest 16 is connected to the upper end of the seat back 14 so as to be vertically adjustable.

[0024] The seat back 14 comprises a seat back frame 22 (see Figures 2 and 3), which is a skeletal member; a seat back pad 24 (see Figure 1), which is a cushioning material; and a trim cover 26 (see Figure 1), which is a surface material. The seat back frame 22 has a pair of left and right side frames 28, an upper frame 30 connecting the upper ends of the left and right side frames 28 in the left-right direction, an upper bracket 32 ​​attached to the upper frame 30, and a lower frame 34 connecting the lower ends of the left and right side frames 28 in the left-right direction. The upper frame 30 and the upper bracket 32 ​​are located at the top of the seat back 14, and the lower frame 34 is located at the bottom of the seat back 14.

[0025] The left and right side frames 28, upper brackets 32, and lower frame 34 are made of, for example, press-formed metal plates, while the upper frame 30 is made of, for example, bent metal pipes. The upper frame 30 has a roughly inverted U-shape when viewed in the front-rear direction, and the upper brackets 32 are spanned between the left and right ends of the lower part of the upper frame 30.

[0026] The seat back pad 24 is made of a foam material such as urethane foam and is placed over the seat back frame 22 from above. The trim cover 26 is formed into a bag shape by sewing together multiple pieces of surface material such as cloth, leather, or synthetic leather and is placed over the seat back pad 24 from above.

[0027] Left and right lumbar wires 36 are stretched between an upper bracket 32, which is provided on the upper part of the seat back frame 22, and a lower frame 34, which is provided on the lower end of the seat back 14. The left and right lumbar wires 36 extend in the vertical direction and are spaced apart in the left and right direction. The lower ends of the left and right lumbar wires 36 are connected in the left and right direction by a connecting wire 38, which is fixed to the lower frame 34. The left and right lumbar wires 36 and the connecting wire 38 are integrally constructed from, for example, a metal wire. A fixing member 40, which is fastened and fixed to the lower frame 34, is attached to the connecting wire 38.

[0028] Lumbar support mechanisms 42 are attached to the left and right lumbar wires 36. The lumbar support mechanism 42 comprises an upper base portion 44 located on the upper part of the seat back 12, an upper lifting portion 46 located in the middle of the seat back 14 in the vertical direction, a lower lifting portion 48 located on the lower part of the seat back 14, and a lower base portion 45 located at the lower end of the seat back 14. The upper base portion 44, the upper lifting portion 46, the lower lifting portion 48, and the lower base portion 45 are manufactured, for example, by resin injection molding, and are substantially plate-shaped with the left-right direction as the longitudinal direction and the front-back direction as the plate thickness direction.

[0029] The upper base portion 44 is molded integrally with, for example, the left and right lumber wires 36, and the left and right sides of the upper base portion 44 are fixed to the left and right lumber wires 36. The upper lifting portion 46 and the lower lifting portion 48 each have their left and right ends slidably engaged with the left and right lumber wires 36 in the vertical direction. The lower base portion 45 is molded integrally with, for example, the connecting wire 38, and the connecting wire 38 is embedded in the lower base portion 45. The upper base portion 44, the upper lifting portion 46, the lower lifting portion 48, and the lower base portion 45 are connected via a feed screw 50, and the upper lifting portion 46 and the lower lifting portion 48 are connected via a feed screw 52. The feed screws 50 and 52 are arranged with their axial direction aligned along the vertical direction.

[0030] Two motors 54 and 56 are attached to the lower lifting section 48. These motors 54 and 56 allow the lead screws 50 and 52 to rotate individually. When the lead screw 50 is rotated by motor 56, the upper lifting section 46 and the lower lifting section 48 move up and down (towards and away from) the upper base section 44 and the lower base section 45 together. When the lead screw 52 is rotated by motor 54, the upper lifting section 46 moves up and down (towards and away from) the lower lifting section 48.

[0031] Left and right arch members 58 are spanned between the upper lifting section 46 and the lower lifting section 48. The left and right arch members 58 are made of a strip-shaped elastic metal or resin plate with the vertical direction as its longitudinal direction, and are curved in an arc shape that protrudes forward when viewed from the left or right. When the upper lifting section 46 approaches the lower lifting section 48 due to the rotation of the motor 54, the curvature of the left and right arch members 58 increases, and the vertically intermediate portions of the arch members 58 protrude forward. Conversely, when the upper lifting section 46 moves away from the lower lifting section 48 due to the rotation of the motor 54, the curvature of the left and right arch members 58 decreases, and the vertically intermediate portions of the left and right arch members 58 retract to the rear.

[0032] A lumbar support plate 60 is positioned on the front side of the left and right arch members 58. The lumbar support plate 60 is made of, for example, injection-molded resin and is formed in a roughly plate-like shape with the vertical direction as the longitudinal direction and the front-to-back direction as the thickness direction. The upper end of this lumbar support plate 60 is connected to the upper base portion 44 via a mounting wire 80, which will be described later. This lumbar support plate 60 is in contact with the back of the seat back pad 24. As described above, the lumbar support plate 60 is displaced in the front-to-back direction as the curvature of the left and right arch members 58 changes. This is configured to adjust the strength of support for the sitter's lower back.

[0033] A mounting bracket 62 is positioned inside the seat back 14 above the lumbar support mechanism 42. The mounting bracket 62 is made of, for example, injection-molded resin and is formed in a roughly plate-like shape with the left-right direction as the longitudinal direction and the front-back direction as the thickness direction. This mounting bracket 62 is positioned in front of the left and right lumbar wires 36 and is supported by the left and right lumbar wires 36 via the mounting wire 80 and the upper base portion 44, which will be described later.

[0034] As shown in Figures 2 to 5, a blower 66 is mounted in the left-right center of the mounting bracket 62. The blower 66 is positioned towards the rear of the mounting bracket 62. The blower 66 is, for example, a centrifugal blower and comprises a centrifugal fan (not shown) with its axis oriented in the front-rear direction, and a case 68 housing the centrifugal fan. The case 68 is made of, for example, injection-molded resin, has a rectangular shape when viewed from the front-rear direction, and is thin in the front-rear direction.

[0035] As shown in Figures 6 and 7, a circular through-hole 70 is formed in the left-right center of the mounting bracket 62. An air intake port 68A provided in the case 68 of the blower 66 is inserted into this through-hole 70. The air intake port 68A is cylindrical with its axis in the front-rear direction and is positioned in contact with the back surface of the seat back pad 24. Although not shown in the figures, multiple air intake holes are formed in the seat back pad 24 at locations opposite to the air intake port 68A.

[0036] As shown in Figures 3 to 5, a bottomed cylindrical fan housing 68B is provided at the rear of the case 68, with the front-to-back direction as its axial direction. A centrifugal fan is housed inside the fan housing 68B. Multiple exhaust ports (not shown) are formed in the peripheral wall of the fan housing 68B.

[0037] A motor (not shown) for rotating a centrifugal fan is provided inside the case 68. When the centrifugal fan is rotated by this motor, air from the front side of the seat back 14 (i.e., the side of the seated person) is drawn into the intake port 68A through the multiple intake holes and exhausted through the multiple exhaust holes. In Figures 3 to 5, 67 is a harness for supplying power to the motor.

[0038] As shown in Figures 4 and 5, the left and right ends of the case 68 are each provided with two fastening pieces 72, one above the other. Each fastening piece 72 is plate-shaped with the front-to-back direction being the thickness direction, and a circular screw hole (not shown) is formed in the center of each fastening piece 72. Corresponding to these four fastening pieces 72, the mounting bracket 62 has four fastening seats 74, as shown in Figures 6 and 7. Each fastening seat 74 is substantially cylindrical with the front-to-back direction being the axial direction.

[0039] A nut 76 is embedded in each fastening seat 74, for example, by insert molding. Each fastening piece 72 is superimposed on each fastening seat 74 from the rear, and screws 78 (see Figures 4 and 5) inserted into the screw holes of each fastening piece 72 are screwed into the nuts 76 of each fastening seat 74. In this way, the blower 66 is attached to the rear surface of the mounting bracket 62.

[0040] As shown in Figures 3 and 4, the mounting bracket 62 is connected to the upper base portion 44 of the lumbar support mechanism 42 via a mounting wire 80. As shown in Figures 8 and 9, the mounting wire 80 is made of bent metal wire and has left and right mounting portions 82 and a connecting portion 84 that connects the left and right mounting portions 82 in the left-right direction. This mounting wire 80 is molded integrally with the upper base portion 44.

[0041] The connecting portion 84 extends in the left-right direction, and most of the connecting portion 84 is embedded in the upper base portion 44. On both the left and right sides of the connecting portion 84, there are portions exposed from the upper base portion 44, and the upper ends of the lumbar support plate 60 are locked to these exposed portions. Both the left and right ends of the connecting portion 84 are bent upward and are integrally connected to the left and right mounting portions 82.

[0042] The left and right mounting portions 82 are positioned exposed on the upper side of the upper base portion 44. Each mounting portion 82 has a first longitudinal extension 82A extending upward from the upper end of the upper base portion 44 (i.e., the upper end of the lumbar support mechanism 42) toward the seat, a first transverse extension 82B extending outward in the left-right direction from the upper end of the first longitudinal extension 82A, a second longitudinal extension 82C extending downward from the left-right outer end of the first transverse extension 82B, and a second transverse extension 82D extending inward in the left-right direction from the lower end of the second longitudinal extension 82C and connecting to the upper end of the upper base portion 44.

[0043] The first longitudinal extension 82A is inclined so as it extends upward, it is slightly inclined towards the rear, and the second longitudinal extension 82C is inclined so as it extends downward, it is slightly inclined towards the rear. The inner ends of the second transverse extension 82D are spaced apart from the lower end of the first longitudinal extension 82A towards the rear, and are bent downward. This bent portion of the second transverse extension 82D is embedded inside the upper base portion 44.

[0044] As shown in Figure 6, the left and right side portions 62S of the mounting bracket 62 are provided with first locking claws 63 that engage with the first longitudinal portions 82A of the left and right mounting portions 82, and second locking claws 64 that engage with the first lateral portions 82B of the left and right mounting portions 82. In this way, the mounting bracket 62 is attached to the mounting wire 80. The mounting wire 80, together with the left and right lumbar wires 36, the lumbar support mechanism 42, the mounting bracket 62, and the blower 66, constitute the "seat back blower mounting structure" of the present invention.

[0045] The first locking claw 63 has an inner claw portion 63A that engages with the first longitudinal extension portion 82A from the inside in the left-right direction, and an outer claw portion 63B that engages with the first longitudinal extension portion 82A from the outside in the left-right direction, and clamps the first longitudinal extension portion 82A in the left-right direction. The second locking claw 64 has an upper claw portion 64A that engages with the first transverse extension portion 82B from above, and a lower claw portion 64B that engages with the first transverse extension portion 82B from below, and clamps the first transverse extension portion 82B in the up-down direction. When the first locking claw 63 is locked to the first longitudinal extension portion 82A, for example, the outer claw portion 63B is elastically deformed and then elastically returns to its original position, and when the second locking claw 64 is locked to the first transverse extension portion 82B, for example, the upper claw portion 64A is elastically deformed and then elastically returns to its original position.

[0046] In the vehicle seat 10 with the above configuration, the back of the occupant sitting on the seat cushion 12 is supported by the seat back 14. Left and right lumbar wires 36 are stretched between the upper and lower parts of the seat back frame 22, and a lumbar support mechanism 42 is attached to the left and right lumbar wires 36. A mounting bracket 62 is positioned above the lumbar support mechanism 42, and a blower 66 is attached to the rear surface of the mounting bracket 62.

[0047] From the upper end of the lumbar support mechanism 42, left and right mounting portions 82 of the mounting wire 80 extend outwards, and the left and right side portions 62S of the mounting bracket 62 are attached to the left and right mounting portions 82. In the event of a rear-end collision of the vehicle, a load from the occupant's back is applied to the mounting bracket 62 from the front (see arrow F in Figure 10). At this time, the left and right mounting portions 82 of the mounting wire 80 deform, causing the mounting bracket 62 and the blower 66 to be displaced to the rear, as shown by the dashed line in Figure 10. As a result, the occupant's back is more likely to slide under the seat back 14, so the timing at which the occupant's head is supported by the headrest 16 is accelerated. This makes it easier to prevent whiplash injuries to the occupant.

[0048] In this embodiment, the first longitudinal extension 82A, which is part of the left and right mounting portions 82 of the mounting wire 80, extends upward from the upper base portion 44 of the lumbar support mechanism 42. From the upper end of the first longitudinal extension 82A, the first transverse extension 82B extends outward in the left-right direction, and from the left-right outer end of the first transverse extension 82B, the second longitudinal extension 82C extends downward. From the lower end of the second longitudinal extension 82C, the second transverse extension 82D extends inward in the left-right direction, and the second transverse extension 82D is connected to the upper base portion 44.

[0049] The first longitudinal extensions 82A of the left and right mounting portions 82 are engaged with the first locking claws 63 provided on the left and right sides 62S of the mounting bracket 62, and the first transverse extensions 82B of the left and right mounting portions 82 are engaged with the second locking claws 64 provided on the left and right sides 62S of the mounting bracket 62. When a load is applied to the mounting bracket 62 from the front, the mounting bracket 62 is allowed to bend (deform) backward between the first longitudinal extensions 82A of the left and right mounting portions 82. This makes it easier for the seated person's back to slide further into the seat back.

[0050] Furthermore, in this embodiment, the mounting bracket 62 and the left and right mounting portions 82 of the mounting wire 80 are configured to elastically deform under the load from the back of the seated person during normal use. This improves the seating comfort for the person sitting.

[0051] Furthermore, in this embodiment, during a rear-end collision, the mounting bracket 62 and the left and right mounting portions 82 of the mounting wire 80 are configured to plastically deform rearward due to the load from the seated person's back. This allows the seated person's energy to be absorbed, thereby suppressing the rebound of the seated person, whose back is tucked into the seat back, towards the front.

[0052] In the above embodiment, the left and right mounting portions 82 of the mounting wire 80 are integrally connected by a connecting portion 84. However, the configuration is not limited to this, and the left and right mounting portions 82 of the mounting wire 80 may be divided into left and right sections.

[0053] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of Symbols]
