[Diagram 3] FIG. [Figure 4] FIG. 4 is a rear view of the plate portion of the lumbar support. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] A vehicle seat according to one embodiment of the present invention (hereinafter, the present embodiment) will be described below with reference to Fig. 1 to Fig. 4. As the vehicle seat according to the present embodiment, a vehicle seat mounted in a vehicle will be described as an example.

[0019] The embodiment described below is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. In other words, the shapes, dimensions, arrangements, and other aspects of the components described below may be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.

[0020] In this specification, the terms indicating directions are defined as shown in FIG. 1. Specifically, in the following description, the "front-rear direction" refers to the front-rear direction as seen by a person (occupant) seated in the vehicle seat, and is the direction that coincides with the vehicle's traveling direction. The "seat width direction" refers to the width direction of the vehicle seat, and coincides with the left-right direction as seen by a person seated in the vehicle seat. Additionally, the "up-down direction" refers to the height direction of the vehicle seat, and coincides with the up-down direction as seen by the vehicle seat from the front.

[0021] [1. Vehicle seats S] The vehicle seat S according to this embodiment has an appearance as shown in FIG. 1. In FIG. 1, a part of the vehicle seat S is shown with a trim cover removed for convenience of illustration. The vehicle seat S has as its main components a seat back S1 which is a backrest portion supporting the back of a seated occupant, a seat cushion S2 which is a seating portion supporting the buttocks of the seated occupant, and a headrest S3 which is disposed on the upper part of the seat back S1 and supports the head of the seated occupant. As shown in FIG. 2, the vehicle seat S has a seat frame F as a skeleton, the main components of which are a seat back frame F1 and a seat cushion frame F2.

[0022] The seat back S1 is constructed by placing a seat back pad S11 on a seat back frame F1, and further covering the seat back pad S11 with a trim cover S12. The seat cushion S2 is constructed by placing a seat cushion pad S21 on a seat cushion frame F2, which serves as a framework, and further covering the seat cushion pad S21 with a trim cover S22. The head rest S3 is formed by disposing a head rest pad S31 on a core material (not shown), and covering it with a trim cover S32. The seat back pad S11 of the seat back S1 and the seat cushion pad S21 of the seat cushion S2 are urethane base materials molded by foam molding using a urethane foam material.

[0023] The seat cushion frame F2 is connected to an upper rail RU of a slide rail device R disposed below the seat cushion frame F2. With this configuration, when the upper rail RU moves along the lower rail RL fixed to the vehicle floor, the entire vehicle seat S including the seat cushion frame F2 slides.

[0024] In this embodiment, the seat cushion frame F2 is connected to the upper rail RU via a rotating link XL as shown in Fig. 2. The rotating links XL are link members disposed on both sides of the seat cushion S2 in the width direction and rotate around a rotation axis along the width direction. The rotating links XL rotate together with the seat cushion S2, thereby adjusting the position of the seat cushion S2 in the up-down direction.

[0025] The lower end of the seatback frame F1 is connected to the rear end of the seat cushion frame F2 via a reclining device 80 as a movable mechanism. The reclining device 80 connects the seatback S1 including the seatback frame F1 to the seat cushion S2 in a state in which the inclination angle of the seatback S1 relative to the seat cushion S2 can be adjusted. In other words, the seatback S1 can rotate relatively to the seat cushion S2 around a reclining shaft 81 along the width direction.

[0026] [2. Seat back frame F1] Hereinafter, the configuration of the seatback frame F1 of the vehicle seat S will be described with reference to Figures 2 and 3. As shown in Figure 2, the seatback frame F1 forms a rectangular frame when the seat frame F is viewed from the front.

[0027] 2 and 3, the seatback frame F1 has a pair of side frames 10 provided at both ends in the seat width direction. As shown in the figures, the seatback frame F1 also has an upper frame 11 that is attached to the upper ends of the side frames 10 to connect the side frames 10. As shown in the figures, the seatback frame F1 also has a lower member frame 12 that is attached to the lower ends of the side frames 10 to connect the side frames 10. Furthermore, an S-spring 15 that supports the back of a seated occupant from behind is installed between the side frames 10.

[0028] The upper frame 11 is a part formed into a downward U-shape when viewed from the front, and is made of a hollow metal pipe member. However, this is not limiting, and the upper frame 11 may be made of a solid member. Both free ends of the upper frame 11 are joined to the upper parts of the left and right side frames 10, respectively. A square cylindrical pillar guide 11a that supports a headrest pillar is attached to the front surface of the horizontal portion of the upper frame 11 that is located at the top. A pair of pillar guides 11a are provided with a gap in the width direction.

[0029] Next, the side frame 10 has a spindle-shaped external shape in a side view. That is, when the side frame 10 is viewed from the side, the front end of the side frame 10 bulges out in an arc shape from a midpoint in the up-down direction. When the vehicle seat S is in use (more precisely, when the seat back S1 is in the reference position), the side frame 10 extends long in a direction slightly inclined (tilted backward) with respect to the vertical direction.

[0030] Next, a description will be given of the lower member frame 12. The lower member frame 12 is formed by processing sheet metal, and is installed between the lower ends of the side frames 10. Furthermore, the upper and lower edge portions of the lower member frame 12 are each formed to have a shape that is bent forward.

[0031] The connecting frame 13 extends along the seat width direction and connects the extending portions 11b of the upper frame 11. The connecting frame 13 is formed from a metal plate into a predetermined shape.

[0032] [3. Features of the seat frame F] A lumbar support 50 (lumbar support device, lumbar support member) is provided on the seat back frame F1 of this embodiment. The lumbar support 50 is composed of a plate member 51 which is a resin panel, an adjustment mechanism 70 incorporating an electromagnetic motor (not shown), and a wire member 71. The plate member 51 is formed in a generally rectangular plate shape from an elastically deformable resin. The plate member 51 is provided below the S-spring 15. The plate member 51 is provided at a position that supports the lumbar region of the seated occupant, as shown in FIG. 2.

[0033] The plate member 51 is disposed in a position extending in the seat width direction and in front of a wire member 71 serving as a support wire. When the adjustment mechanism 70 is actuated and the wire member 71 is curved so as to protrude forward, the plate member 51 elastically bends forward at the center.

[0034] With this structure, the lumbar support 50 can change the support position of the lower back of the seated person. Specifically, when the electromagnetic motor of the adjustment mechanism 70 is not operating, the wire member 71 is not pulled, and the plate member 51 is in a flat state without bending, as shown in Fig. 2. On the other hand, when the electromagnetic motor of the adjustment mechanism 70 is operating, the wire member 71 is pulled, and the plate member 51 bends forward at the center.

[0035] At this time, the bent plate member 51 also bends the seat back pad S11 forward, and the bent seat back pad S11 pushes the lumbar region of the seated person from the rear to the front. This changes the support position of the lumbar region of the seated person. In other words, the amount of bending (the amount of protrusion forward) of the plate member 51 changes according to the amount of operation of the electromagnetic motor, and the support position of the lumbar region of the seated person is changed as desired. This allows the lumbar region of the seated person to be properly supported.

[0036] In addition, the seat back S1 on which the lumbar support 50 is provided is also provided with a sensor 60, which is a Doppler type biosensor. The sensor 60 is a sensor that detects the bioinformation of the seated occupant. The bioinformation of the seated occupant is information indicating the heart rate, pulse rate, pulse volume, respiratory rate, and respiratory volume. In other words, the sensor 60 is a biosensor that can detect the heart rate and respiration of the seated occupant.

[0037] In detail, the sensor 60 is composed of an irradiation unit 61 that irradiates radio waves, a receiving unit 62 that receives the radio waves, and a resin housing 63 that contains the irradiation unit 61 and the receiving unit 62. The radio waves irradiated by the receiving unit 62 may be any radio waves having a frequency that is reflected by the skin surface of a living body, but it is usually preferable that the radio waves are microwaves.

[0038] As described above, the sensor 60 disposed inside the seat back pad S11 irradiates radio waves from the irradiation unit 61 toward the seating surface of the seat back S1. At this time, the radio waves irradiated by the irradiation unit 61 are reflected by the skin surface of the seated person, and the reflected radio waves are received by the receiving unit 62. Since the skin surface of the seated person moves minutely due to the heartbeat and breathing, the frequency of the radio waves irradiated by the irradiation unit 61 is different from the frequency of the radio waves received by the receiving unit 62. Therefore, based on the difference between the frequency of the radio waves irradiated by the irradiation unit 61 and the frequency of the radio waves received by the receiving unit 62, the biological information of the seated person, that is, the respiratory rate, heart rate, etc., are detected. In other words, the biological information of the seated person is detected by utilizing the Doppler effect.

[0039] In this way, the sensor 60 detects the biological information of the seated person based on the minute movements of the skin surface of the seated person, so the location where the sensor 60 is installed is limited. More specifically, the sensor 60 has a resin housing and has a predetermined hardness, so that the sensor 60 is not exposed to the seating surface of the seat back pad S11 in order to prevent the seated person from feeling uncomfortable when sitting. For this reason, the sensor 60 is installed on the back surface 51a of the plate member 51 so as not to be exposed to the seating surface of the seat back pad S11.

[0040] Specifically, the lumbar support 50 has a flat plate member 51 extending in the seat width direction, and an adjustment mechanism 70 for adjusting the position of the lumbar support 50 in the fore-and-aft direction is arranged on the back surface 51a of the plate member 51, and the sensor 60 is arranged in an upper position on the back surface 51a of the plate member 51, avoiding the adjustment mechanism 70.

[0041] In the vehicle seat S of this embodiment configured in this manner, the sensor 60 can be positioned on the back side of the lumbar support 50 equipped with the adjustment mechanism 70 (more specifically, on the back side 51a of the plate member 51), making it possible to appropriately detect biometric information by the sensor 60 while ensuring freedom of layout of the sensor 60.

[0042] The adjustment mechanism 70 extends along the seat width direction, and the sensor 60 is preferably disposed in a position above or below the adjustment mechanism 70. In the illustrated example, the sensor 60 is disposed in a position above the adjustment mechanism 70. With this configuration, the sensor 60 can be disposed while appropriately avoiding the adjustment mechanism 70 extending in the seat width direction, and the sensor 60 can appropriately detect biological information.

[0043] Further, a wire member 71 that is connected to the side frame 10 of the seatback frame F1 is connected to the adjustment mechanism 70, and the sensor 60 is disposed at a position that avoids the wire member 71. Specifically, the sensor 60 is disposed above the wire member 71 in the up-down direction. With this configuration, the sensor 60 is disposed while appropriately avoiding the wire member 71 that is connected to the adjustment mechanism 70, and it becomes possible for the sensor 60 to appropriately detect biological information.

[0044] Furthermore, the plate member 51 has lattice ribs 52 on the back surface 51a, and the sensor 60 is disposed at a position avoiding the lattice ribs 52 (FIG. 3). Specifically, as shown in FIG. 3, the sensor 60 is disposed at a position avoiding the protruding portion of the lattice ribs 52 formed protruding rearward from the back surface 51a of the plate member 51. With this configuration, the sensor 60 is disposed on the back surface 51a of the plate member 51 while avoiding the lattice ribs 52, and it becomes possible for the sensor 60 to appropriately detect biological information.

[0045] Furthermore, the plate member 51 has a recess 53 that is thinner in the front-rear direction than the surrounding area, and the sensor 60 is attached to this recess 53 (FIGS. 3 and 4). With this configuration, the sensor 60 is stably disposed by disposing the sensor 60 in the recess 53 formed in the back surface 51a of the plate member 51, and the sensor 60 can appropriately detect biological information.

[0046] Moreover, the sensor 60 is disposed at a position eccentric from the center on the back surface 51a of the plate member 51 (FIG. 4). With such a configuration, since the area around the spine of the seated person's body is concave, it becomes possible for the sensor 60 to detect biological information on the left or right side of the back of the seated person's body that is always in contact with the seating surface.

[0047] In addition, a wiring member (not shown) such as a harness connected to a component (electrical component) different from the sensor 60 may be disposed rearward of the sensor 60 and on the opposite side of the sensor 60 in the seat width direction. With this configuration, the wiring member connected to a component different from the sensor 60 is prevented from affecting the sensor 60.

[0048] The sensor 60 includes an irradiation unit 61 that irradiates radio waves, a receiving unit 62 that receives radio waves reflected from a seated occupant, and a housing 63 that contains the irradiation unit 61 and the receiving unit 62, and the irradiation unit 61 and the receiving unit 62 are disposed above the adjustment mechanism 70 in the vertical direction (FIG. 4). With this configuration, the irradiation unit 61 and the receiving unit 62 are disposed at an appropriate height while avoiding the adjustment mechanism 70, so that the sensor 60 can appropriately detect biological information.

[0049] The vehicle seat S of this embodiment includes a headrest S3 for supporting the head of a seated occupant, a seat cushion S2 for supporting the buttocks of the seated occupant, a seat cushion frame F2 for forming the framework of the seat cushion S2, a slide rail device R arranged at the bottom of the seat cushion frame F2, a seat back pad S11 placed on the seat back frame F1, a seat cushion pad S21 placed on the seat cushion frame F2, a trim cover S12 for covering the seat back pad S11, and a trim cover S22 for covering the seat cushion pad S21. With this configuration, it is possible to provide a vehicle seat S including a sensor 60 and a lumbar support 50.

[0050] <Modification> Although the configuration of the vehicle seat S according to this embodiment has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and does not limit the present invention. In other words, the present invention can be modified and improved without departing from the spirit and scope of the present invention, and of course, the present invention includes equivalents thereof.

[0051] In the above embodiment, the sensor 60 was positioned at an upper position on the back surface 51a of the plate member 51, avoiding the adjustment mechanism 70, but the sensor 60 may also be positioned at a lower position on the back surface 51a of the plate member 51, avoiding the adjustment mechanism 70.

[0052] In the above embodiment, the sensor 60 was positioned on the back surface 51a of the plate member 51 at a position slightly off-center to the left of the center, but the sensor 60 may also be positioned on the back surface 51a of the plate member 51 at a position slightly off-center to the right of the center.

[0053] The vehicle seat according to the present embodiment has been described above as an example of a vehicle seat mounted on a vehicle. The vehicle seat according to the present embodiment is not limited to a vehicle seat mounted on a ground-traveling vehicle having wheels such as an automobile or a train, but may be a seat mounted on an aircraft or a ship that moves on a road other than the ground.
