Summary of the Invention

[0004] By the way, when providing a duct for connecting a blower and a ventilation passage and a sensor for acquiring biometric information of a seated person in a vehicle seat, it is desirable to suppress interference between the duct and the sensor. Therefore, an object is to provide a vehicle seat and a method for manufacturing a vehicle seat that can suppress interference between a duct and a sensor.

[0005] In addition, in a vehicle seat, it is desirable that vibration when a blower operates is difficult to be transmitted to a seated person. Therefore, an object is to provide a vehicle seat that can suppress vibration when a blower operates.

[0006] The vehicle seat comprises a seat frame having left and right side frames spaced apart in the left-right direction, a pressure-receiving member for supporting the occupant, the pressure-receiving member being positioned between the left and right side frames, a pad covering the seat frame and the pressure-receiving member, the pad having an internal ventilation passage, a blower, a duct connecting the blower and the ventilation passage, and a sensor capable of acquiring the occupant's biometric information. The pressure-receiving member has a reinforcing wire extending in a first direction perpendicular to the left-right direction, the duct is positioned on one side in the left-right direction relative to the reinforcing wire, and the sensor is positioned on the other side in the left-right direction relative to the reinforcing wire.

[0007] By positioning the duct on one side of the reinforcing wire in the left-right direction, and the sensor on the other side of the reinforcing wire in the left-right direction, interference between the duct and the sensor can be suppressed.

[0008] The duct can be positioned on one side in the left-right direction relative to the left-right center of the pressure-receiving member, and the sensor can be positioned on the other side in the left-right direction relative to the left-right center of the pressure-receiving member.

[0009] By positioning the duct on one side of the left-right center of the pressure-receiving member, and the sensor on the other side of the left-right center of the pressure-receiving member, interference between the duct and the sensor can be suppressed.

[0010] The pressure-receiving member has a first side wire positioned on one side in the left-right direction relative to the reinforcing wire, and a second side wire positioned on the other side in the left-right direction relative to the reinforcing wire, and the duct and the sensor can be configured to be positioned between the first side wire and the second side wire as viewed from the seated person's side.

[0011] The duct and sensor are positioned between the first and second side wires, as viewed from the seated person's side, so that the duct and sensor can be protected by the first and second side wires.

[0012] The pressure-receiving member includes a first sensor mounting portion to which the sensor can be attached, the first sensor mounting portion being positioned adjacent to one side of the reinforcing wire in the left-right direction, and a second sensor mounting portion to which the sensor can be attached, the second sensor mounting portion being positioned adjacent to the other side of the reinforcing wire in the left-right direction. The first sensor mounting portion and the second sensor mounting portion each have a first clamping portion that holds the sensor when the sensor is attached, the first clamping portion of the first sensor mounting portion being positioned between the center of the first sensor mounting portion and the reinforcing wire in the left-right direction, and the first clamping portion of the second sensor mounting portion being positioned between the center of the second sensor mounting portion and the reinforcing wire in the left-right direction.

[0013] In the left-right direction, the first clamping portion of the first sensor mounting portion is positioned between the center of the first sensor mounting portion and the reinforcing wire, and the first clamping portion of the second sensor mounting portion is positioned between the center of the second sensor mounting portion and the reinforcing wire. This allows the first clamping portion to be positioned close to the reinforcing wire. As a result, the rigidity of the first clamping portion can be improved by the reinforcing wire.

[0014] The first sensor mounting portion and the second sensor mounting portion can each be configured to have a second clamping portion that holds the sensor when the sensor is mounted, and a third clamping portion that holds the sensor when the sensor is mounted, the third clamping portion being arranged side by side with the second clamping portion in the first direction.

[0015] The first sensor mounting portion and the second sensor mounting portion each have a first clamping portion, a second clamping portion, and a third clamping portion, respectively, so that when a sensor is attached, the sensor can be firmly attached to the pressure receiving member.

[0016] The pressure-receiving member may have a configuration comprising: a first hole through which the duct can pass, located adjacent to one side in the left-right direction of the first sensor mounting portion; and a second hole through which the duct can pass, located adjacent to the other side in the left-right direction of the second sensor mounting portion.

[0017] In the left-right direction, the first hole is positioned on the opposite side of the first clamping portion from the center of the first sensor mounting portion, and the second hole is positioned on the opposite side of the first clamping portion from the center of the second sensor mounting portion. Therefore, when a duct is passed through, the first clamping portion and the duct can be positioned apart. This suppresses interference between the first clamping portion and the duct.

[0018] The vehicle seat may be configured to include a harness electrically connected to the sensor, with the harness extending in the left-right direction from the sensor to the side opposite to the side where the first clamping portion is located.

[0019] The harness extends in the left-right direction from the sensor to the side opposite to where the first clamping portion is located, thereby suppressing interference between the harness and the first clamping portion.

[0020] The first sensor mounting portion and the second sensor mounting portion can each be configured to have a recess in the left-right direction that extends inward from the edge opposite to the side on which the first clamping portion is located toward the first clamping portion.

[0021] The first sensor mounting portion and the second sensor mounting portion each have recesses, which helps to suppress interference between the harness and the sensor mounting portion when a sensor with a harness connected is mounted.

[0022] The pressure-receiving member has a resin member that covers the reinforcing wire, and the resin member can be made of elastomer.

[0023] By using an elastomer as the resin component covering the reinforcing wire, the seating comfort of vehicle seats can be improved.

[0024] The pressure-receiving member has a through-hole for the duct and a mesh-shaped portion, and the edge of the through-hole can be made thicker than the portion forming the mesh of the mesh portion when viewed from the seated person's side.

[0025] The edge of the through-hole of the pressure-bearing member is thicker than the part forming the mesh of the mesh part when viewed from the seated person side, making it difficult for the through-hole to deform. This can suppress the interference between the edge of the through-hole and the duct passed through the through-hole.

[0026] A part of the part forming the mesh of the mesh part can be configured to be connected to the edge of the through-hole.

[0027] Since a part of the part forming the mesh of the mesh part of the pressure-bearing member is connected to the edge of the through-hole, it is more difficult for the through-hole to deform. This can further suppress the interference between the edge of the through-hole and the duct.

[0028] The pressure-bearing member has an attachment part for attaching another member to the pressure-bearing member, and the attachment part can be configured to include a first attachment part arranged in front of the sensor.

[0029] Since the first attachment part is arranged in front of the sensor, the interference between the member attached to the first attachment part and the sensor can be suppressed.

[0030] The manufacturing method of the vehicle seat is a manufacturing method of a vehicle seat in which the pressure-bearing member has a first clamping part, a second clamping part, and a third clamping part, and includes a step of arranging the duct on one side in the left-right direction with respect to the reinforcing wire, and a step of sliding the sensor in the left-right direction from the other side in the left-right direction toward the reinforcing wire and engaging with the second clamping part, the third clamping part, and the first clamping part.

[0031] By sliding the sensor in the left-right direction from the side opposite to the side where the duct is arranged in the left-right direction toward the reinforcing wire and engaging with the second clamping part, the third clamping part, and the first clamping part, it is possible to suppress the interference between the sensor and the duct when attaching the sensor.

[0032] A vehicle seat comprises a seat frame having left and right side frames spaced apart in the left-right direction, a pressure-receiving member for supporting a seated person, the pressure-receiving member being positioned between the left and right side frames, and a blower attached to the pressure-receiving member, wherein the pressure-receiving member includes an elastic member, and the blower is attached to the elastic member.

[0033] The pressure-receiving member includes an elastic member, and the blower is attached to the elastic member, thereby suppressing vibrations when the blower is operating.

[0034] The pressure-receiving member can be configured in the shape of a plate.

[0035] The plate shape of the pressure-receiving member makes it easy to attach the blower to it.

[0036] The elastic member can be made of an elastomer.

[0037] By making the elastic member to which the blower is attached from an elastomer, vibrations when the blower is operating can be effectively suppressed.

[0038] The pressure-receiving member can be configured to include the elastic member and a wire covered by the elastic member.

[0039] The pressure-receiving member has a mounting portion for attaching a member other than the blower to the pressure-receiving member, and the blower can be configured to be positioned so as to not overlap with the mounting portion when viewed from the seated person's side.

[0040] The blower is positioned so that it does not overlap with the mounting area when viewed from the seated person's side, making it less likely to get in the way when attaching other components to the mounting area.

[0041] The vehicle seat comprises a pad covering the seat frame, the pad having an internal ventilation passage, and a duct connecting the blower and the ventilation passage, wherein the duct can be positioned so as to not overlap with the mounting portion when viewed from the seated person's side.

[0042] The duct is positioned so that it does not overlap with the mounting area when viewed from the seated person's side, making it less likely to get in the way when attaching components other than the blower to the mounting area.

[0043] The vehicle seat comprises a pad covering the seat frame, the pad having an internal ventilation passage, and a duct connecting the blower and the ventilation passage, wherein the blower is positioned on the opposite side of the pressure-receiving member from the seated person's side, the pressure-receiving member has a through hole, and the duct extends from the opposite side of the pressure-receiving member from the seated person's side through the through hole towards the seated person's side.

[0044] Because the duct extends from the opposite side of the pressure-receiving member from the side facing the seated person, through a through-hole in the pressure-receiving member, the duct can be arranged compactly.

[0045] The side frame is elongated in a direction perpendicular to the left-right direction, and the blower can be configured such that the longitudinal position of the side frame coincides with the through hole.

[0046] By aligning the longitudinal position of the blower's side frame with the through-hole of the pressure-receiving member, the distance from the blower to the through-hole can be shortened. This allows for a shorter duct.

[0047] The side frame is elongated in a direction perpendicular to the left-right direction, and the vehicle seat further comprises a side frame cover that covers at least the inside in the left-right direction of one end of the side frame in the longitudinal direction, and the blower can be configured so that its position in the longitudinal direction is closer to the other end of the side frame in the longitudinal direction than the side frame cover.

[0048] The blower's position in the longitudinal direction is closer to the other end of the side frame in the longitudinal direction than to the side frame cover, allowing the blower to be positioned away from the side frame cover.

[0049] The vehicle seat comprises a pad covering the seat frame, the pad having an internal ventilation passage, and a duct connecting the blower and the ventilation passage. The side frame is elongated in a direction perpendicular to the left-right direction, and the vehicle seat further comprises a side frame cover that covers at least the inside in the left-right direction of one end of the side frame in the longitudinal direction, and the connection portion between the duct and the ventilation passage can be configured such that its position in the longitudinal direction is closer to the other end of the side frame in the longitudinal direction than the side frame cover.

[0050] The connection point between the duct and the ventilation passage is positioned closer to the other end of the side frame in the longitudinal direction than to the side frame cover, allowing the connection point between the duct and the ventilation passage to be positioned away from the side frame cover.

[0051] The side frame is elongated in a direction perpendicular to the left-right direction, and the vehicle seat further comprises a side frame cover that covers at least the inside in the left-right direction of one end of the side frame in the longitudinal direction, and the blower can be configured so that its position in the longitudinal direction overlaps with the side frame cover.

[0052] The position of the blower in the longitudinal direction overlaps with the side frame cover, allowing the blower to be positioned within the width of the side frame cover in the longitudinal direction of the side frame.

[0053] The blower can be configured to be directly attached to the elastic member.

[0054] The blower is directly attached to the elastic member, which reduces the number of parts. [Brief explanation of the drawing]

[0056] Next, the first embodiment will be described. In this specification, front-to-back, left-to-right, and up-and-down correspond to the front-to-back, left-to-right, and up-and-down directions as viewed from the perspective of a person sitting in the seat (seated person). As shown in Figure 1, the vehicle seat of the embodiment is configured as a vehicle seat S to be installed in an automobile as a vehicle. The vehicle seat S comprises a seat cushion S1, a seat back S2, and a headrest S3.

[0057] Furthermore, the vehicle seat S is equipped with a movement mechanism SR that allows the seat cushion S1 to move relative to the floor of the vehicle. The movement mechanism SR has left and right lower rails R1 fixed to the floor of the vehicle, and left and right upper rails R2 that engage with the lower rails R1 so as to be slidable forward and backward. The seat cushion S1 is fixed to the left and right upper rails R2. As a result, the seat cushion S1 (vehicle seat S) is slidable forward and backward relative to the floor of the vehicle.

[0058] As shown in Figures 1 and 2, the vehicle seat S comprises a seat frame F, a pad P that covers the seat frame F, and a surface material SK that covers the seat frame F and the pad P. The seat frame F includes the seat cushion frame F1, which is the frame for the seat cushion S1, and the seat back frame F2, which is the frame for the seat back S2.

[0059] The pad P is made of a foamed resin such as urethane foam, and includes a seat cushion pad P1 that covers the seat cushion frame F1 and a seat back pad P2 that covers the seat back frame F2. The seat cushion pad P1 has a first central part PC1 and left and right first side parts PS1 that are provided on the left and right sides of the first central part PC1 and protrude above the first central part PC1. The seat back pad P2 has a second central part PC2 and left and right second side parts PS2 that are provided on the left and right sides of the second central part PC2 and protrude in front of the second central part PC2.

[0060] The surface material SK is made of, for example, leather or fabric, and includes a seat cushion surface material SK1 that covers the seat cushion frame F1 and seat cushion pad P1, and a seat back surface material SK2 that covers the seat back frame F2 and seat back pad P2.

[0061] As shown in Figure 2, the seat cushion S1 comprises a seat cushion frame F1, a first pressure-receiving member 30 as a pressure-receiving member, and left and right side frame covers 40. The seat cushion S1 is constructed by covering the seat cushion frame F1, the first pressure-receiving member 30, and the side frame covers 40 with a seat cushion pad P1 and a seat cushion surface SK1. The seat cushion pad P1 covers the seat cushion frame F1, the first pressure-receiving member 30, and the side frame covers 40.

[0062] The seat cushion frame F1 includes first side frames 11 as left and right side frames, a front frame 12 and a rear frame 13 as a pair of connecting frames, and a pan frame 14.

[0063] The first side frame 11 is made of a metal plate and is elongated in the front-to-back direction, which is perpendicular to the left-to-right direction. In this embodiment, the front-to-back direction corresponds to the "longitudinal direction of the side frame" or the "first direction". The left and right first side frames 11 are spaced apart in the left-to-right direction.

[0064] The front frame 12 and the rear frame 13 connect the left and right first side frames 11. Specifically, the front frame 12 is made of metal pipe and connects the front ends of the left and right first side frames 11. The rear frame 13 is made of metal pipe and connects the rear ends of the left and right first side frames 11. The front frame 12 and the rear frame 13 are spaced apart in the front-rear direction.

[0065] The pan frame 14 is made of a metal plate and connects the front ends of the left and right first side frames 11.

[0066] The seat back S2 comprises a seat back frame F2 and a second pressure-receiving member 50. The seat back S2 is constructed by covering the seat back frame F2 and the second pressure-receiving member 50 with a seat back pad P2 and a seat back surface SK2. The seat back pad P2 covers the seat back frame F2 and the second pressure-receiving member 50.

[0067] The seat back frame F2 includes left and right lower side frames 22, a pipe frame 23, a lower frame 24, and a bridging frame 25.

[0068] The lower side frame 22 is made of a metal plate and is formed to be long in the vertical direction, which is perpendicular to the left-right direction. The pipe frame 23 is made of a metal pipe and has left and right upper side frames 23A and upper frames 23B that extend to the left and right so as to connect the upper ends of the upper side frames 23A.

[0069] The upper side frame 23A is connected to the upper part of the lower side frame 22 and together with the lower side frame 22 constitutes the second side frames 21, which are the left and right frames of the seat back frame F2. The left and right second side frames 21 are formed to be long in the vertical direction and spaced apart in the left and right direction. A pair of holders 26 for holding the headrest S3 are fixed to the upper frame 23B.

[0070] The lower frame 24 and the bridging frame 25 connect the left and right second side frames 21. Specifically, the lower frame 24 is made of a metal pipe or metal plate and connects the lower parts of the left and right second side frames 21. The bridging frame 25 is made of a metal plate and connects the upper parts of the left and right second side frames 21. The bridging frame 25 is located below the upper frame 23B. The lower frame 24 and the bridging frame 25 are spaced apart in the vertical direction.

[0071] The second pressure-receiving member 50 is a plate-shaped member that supports the seated person and is positioned between the left and right second side frames 21. The second pressure-receiving member 50 has a resin member 51 and an attachment wire 52. The mounting wire 52 is a metal wire that reinforces the resin member 51, and a portion of it is covered by the resin member 31. The mounting wire 52 is stretched between the lower frame 24 and the bridging frame 25.

[0072] The resin member 51 is the part that supports the seated person from behind and covers a portion of the mounting wire 52. The resin member 51 is plate-shaped. The resin member 51 has a central support portion 51A and left and right side support portions 51B. The side support portions 51B extend diagonally forward from both the left and right ends of the central support portion 51A so that they are positioned forward as they move outward in the left-right direction.

[0073] The second pressure-receiving member 50 is attached to the seat back frame F2 by fixing the lower end of the mounting wire 52 to the lower frame 24 and inserting the upper end of the mounting wire 52 into, for example, a hole formed in the bridging frame 25.

[0074] The first pressure-receiving member 30 is a plate-shaped member that supports the seated person and is positioned between the left and right first side frames 11. As shown in Figure 3, the first pressure-receiving member 30 has a resin member 31 as an elastic member and vertical wires 32 and horizontal wires 33 as wires. In this embodiment, the vertical wires 32 correspond to the "first reinforcing wires" and the horizontal wires 33 correspond to the "second reinforcing wires".

[0075] The vertical wires 32 and horizontal wires 33 are metal wires that reinforce the resin member 31 and are covered by the resin member 31. In other words, the resin member 31 covers the vertical wires 32 and horizontal wires 33. As shown in Figure 4, the vertical wire 32 extends in the front-to-back direction when viewed from above. In this embodiment, the top corresponds to the "seater side," and the bottom corresponds to the "opposite side from the seater side." The vertical wire 32 is stretched between the front frame 12 and the rear frame 13 via the resin member 31. In this embodiment, the front-to-back direction corresponds to the "direction in which the first reinforcing wire is stretched."

[0076] The vertical wire 32 includes a center wire 32A, a first side wire 32B, and a second side wire 32C. The center wire 32A is positioned in the left-right center of the first pressure-receiving member 30. The center wire 32A is positioned between the first side wire 32B and the second side wire 32C. In this embodiment, the center wire 32A corresponds to the "reinforcement wire".

[0077] The first side wire 32B is positioned to the right of the center wire 32A, which is one side in the left-right direction. The center wire 32A and the first side wire 32B are spaced apart in the left-right direction. In this embodiment, the left-right direction corresponds to "the direction perpendicular to the direction in which the first reinforcing wire is stretched." The second side wire 32C is positioned to the left of the center wire 32A, which is the other side in the left-right direction. The center wire 32A and the second side wire 32C are spaced apart in the left-right direction.

[0078] In this embodiment, the center wire 32A, the first side wire 32B, and the second side wire 32C have the same shape. Specifically, as shown in Figure 5, the center wire 32A, the first side wire 32B, and the second side wire 32C each have a wire body 321, a front hook 322, and a rear hook 323. The wire body 321 has a first extended portion 321A, a second extended portion 321B, a third extended portion 321C, a first bent portion 321D, and a second bent portion 321E as a bent portion.

[0079] The front hook 322 is the part that engages with the front frame 12 via the resin member 31. The front hook 322 extends forward from the front end of the wire body 321 (first extension portion 321A) in an arc shape. The rear hook 323 is the part that engages with the rear frame 13 via the resin member 31. The rear hook 323 extends diagonally upward and backward from the rear end of the wire body 321 (third extension portion 321C), and is curved so that its rear end forms an arc shape.

[0080] The first extension portion 321A extends approximately in the front-to-back direction. Specifically, the first extension portion 321A extends diagonally downward and backward. The second extension portion 321B extends diagonally upward and backward from the rear end of the first extension portion 321A. The first bent portion 321D is formed between the first extension portion 321A and the second extension portion 321B. The third extension portion 321C extends diagonally downward and backward from the rear end of the second extension portion 321B. The third extension portion 321C extends approximately parallel to the first extension portion 321A. The second bent portion 321E is formed between the second extension portion 321B and the third extension portion 321C.

[0081] As shown in Figure 4, the transverse wire 33 extends perpendicular to the vertical wire 32 when viewed from above. Specifically, the transverse wire 33 extends in the left-right direction when viewed from above. The transverse wire 33 intersects with the vertical wire 32 when viewed from above. The second reinforcing wire is positioned to pass over the first extended portion 321A (see Figure 5) of the vertical wire 32 and span across the first side wire 32B, the center wire 32A, and the second side wire 32C. The transverse wire 33 also passes through a portion of the edges of the through holes 351 and 352 provided in the resin member 31. Specifically, the transverse wire 33 passes through the leading edges 351A and 352A of the through holes 351 and 352.

[0082] The resin member 31 is plate-shaped. The resin member 31 has a main body portion 310, a front latch portion 320, and a rear latch portion 330. The front fastening portion 320 is the part that hooks onto the front frame 12 and covers the front hook 322 of the vertical wire 32 (see Figure 5).

[0083] The rear fastening portion 330 is the part that hooks onto the rear frame 13 and covers the rear hook 323 of the vertical wire 32 (see Figure 5). The first pressure-receiving member 30 is attached to the seat cushion frame F1 by having its front fastening portion 320 hooked onto the front frame 12 and its rear fastening portion 330 hooked onto the rear frame 13.

[0084] The main body 310 is the part that supports the seated person from below and covers the wire body 321 of the vertical wire 32 (see Figure 5) and the horizontal wire 33.

[0099] The vehicle seat S further comprises a blower 110, a duct 120, an ECU 130 as a control device, and a sensor 140. The blower 110 is, for example, a sirocco fan. The ECU 130 is an electronic control unit for controlling the blower 110 and includes a CPU, RAM, ROM, input / output circuits, etc. The sensor 140 is a sensor for detecting a person sitting in the vehicle seat S. The sensor 140 is capable of acquiring the occupant's biometric information. The sensor 140 is, for example, a pressure sensor that detects the load from the occupant.

[0100] The blower 110 is positioned below the first pressure-receiving member 30. Furthermore, the blower 110 is attached to the first pressure-receiving member 30. In other words, the blower 110 is attached to the lower surface of the first pressure-receiving member 30, which is the side opposite to the seated person. The blower 110 is attached to the resin member 31 of the first pressure-receiving member 30. In this embodiment, the blower 110 is directly attached to the resin member 31 without the use of a bracket or the like. The blower 110 is supported by the seat frame F via the resin member 31 (first pressure-receiving member 30). In other words, the blower 110 is not directly supported by the seat frame F.

[0101] As shown in Figure 7, the blower 110 includes an impeller 111, a motor that rotates the impeller 111, a casing 113 that houses the impeller 111 and the motor, and two mounting portions 114.

The second blower mounting section 390B is provided in front of the first blower mounting section 390A.

[0107] The blower mounting section 390 is provided in contact with the frame section 370. Specifically, the rear edge of the first blower mounting section 390A is provided in contact with the fifth frame section 375 of the frame section 370. The left edge of the second blower mounting section 390B (the end closest to the left-right center of the first pressure receiving member 30) is provided in contact with the first frame section 371 of the frame section 370. The first frame section 371 protrudes above the second blower mounting section 390B. Also, the first frame section 371 protrudes below the second blower mounting section 390B. The fifth frame section 375 protrudes above the first blower mounting section 390A. Also, the fifth frame section 375 protrudes below the first blower mounting section 390A.

[0108] A thickened portion 361 is provided around the blower mounting portion 390. In the first embodiment, the thickened portion 361 is the mesh portion of the first mesh portion 360A. The thickened portion 361 is provided in contact with the blower mounting portion 390. Specifically, the thickened portion 361 is provided in contact with the front edge and the left and right edges of the first blower mounting portion 390A. The thickened portion 361 is also provided in contact with the front and rear edges and the right edge of the second blower mounting portion 390B. The thickened portion 361 protrudes above the blower mounting portion 390. The thickened portion 361 also protrudes below the blower mounting portion 390. The thickened portion 361 includes thickened portions 361A to 361F.

[0109] Thickened portion 361A is in contact with the front edge of the first blower mounting portion 390A, thickened portion 361B is in contact with the right edge of the first blower mounting portion 390A, and thickened portion 361C is in contact with the left edge of the first blower mounting portion 390A.

Also, the thickened portions 361D, 361E, and 361F protrude below the second blower mounting portion 390B.

[0111] As shown in Figure 8, the mounting member 150 has an engaging portion 152 that engages from top to bottom with the first through hole 391 of the blower mounting portion 390 provided on the first pressure receiving member 30, and with the second through hole 115 of the mounting portion 114 provided on the blower 110. The tip of the engaging portion 152 protrudes below the blower mounting portion 390.

[0112] The thickened portion 361 (361A to 361F) protrudes above the mounting member 150. Specifically, the thickened portion 361 protrudes above the head portion 151 of the mounting member 150. In other words, the head portion 151 of the mounting member 150 does not protrude above the thickened portion 361 (see dashed line).

[0113] The first mounting portion 114A of the blower 110 is positioned below the first blower mounting portion 390A, in contact with the thickened portion 361B and the thickened portion 361C. Here, one of the thickened portion 361B and the thickened portion 361C corresponds to the "first thickened portion," and the other of the thickened portion 361B and the thickened portion 361C corresponds to the "second thickened portion."

[0114] The second mounting portion 114B of the blower 110 is positioned below the second blower mounting portion 390B, in contact with the thickened portion 361D and the thickened portion 361E. Here, one of the thickened portion 361D and the thickened portion 361E corresponds to the "first thickened portion," and the other of the thickened portion 361D and the thickened portion 361E corresponds to the "second thickened portion."

[0115] As shown in Figures 9(a) and (b), the blower 110 is positioned so as not to overlap with the mounting portion 380 when viewed from above. Specifically, the blower 110 is positioned so as not to overlap with any of the first mounting portion 380A, the second mounting portion 380B, and the third mounting portion 380C when viewed from above.

[0116] The blower 110 is positioned so as not to overlap with the vertical wires 32 when viewed from above. Specifically, the blower 110 is positioned so as not to overlap with the center wire 32A, the first side wire 32B, or the second side wire 32C when viewed from above. Furthermore, the blower 110 is positioned so as not to overlap with the horizontal wires 33 when viewed from above.

[0117] The blower 110 is positioned to the right of the center wire 32A. Specifically, when viewed from above, the blower 110 is positioned between the center wire 32A and the first side wire 32B. In this embodiment, one of the center wire 32A and the first side wire 32B corresponds to the "first wire," and the other of the center wire 32A and the first side wire 32B corresponds to the "second wire."

[0118] As shown in Figure 5, the blower 110 is positioned so that its front-to-back position coincides with the first bend 321D and the second bend 321E of the vertical wire 32. Also, when viewed from the left-to-right direction, the blower 110 is positioned so that it coincides with both the first bend 321D and the second bend 321E of the vertical wire 32. The blower 110 is positioned between the bends 321D and 321E of the center wire 32A and the bends 321D and 321E of the first side wire 32B.

[0119] As shown in Figure 6, the blower 110 is positioned so that its position in the front-to-back direction coincides with that of the side frame cover 40. Specifically, when viewed from above, the blower 110 is positioned behind the front end of the side frame cover 40 and in front of the rear end of the side frame cover 40. In the first embodiment, when viewed from above, the blower 110 is positioned between the left and right side frame covers 40.

[0120] As shown in Figure 10, the duct 120 is a tubular member that connects the blower 110 and the ventilation passage 60 provided in the seat cushion pad P1. The seat cushion pad P1 has a ventilation passage 60 inside. For example, the ventilation passage 60 includes a first ventilation passage 61, a second ventilation passage 62, and a plurality of third ventilation passages 63. The first ventilation passage 61 is provided to connect the second ventilation passage 62 and the space below the seat cushion pad P1. The third ventilation passages 63 are provided to connect the second ventilation passage 62 and the space above the seat cushion pad P1.

[0121] The duct 120 has one end, the first end 121, connected to the outlet 113A of the blower 110, and the other end, the second end 122, connected to the first ventilation passage 61 of the ventilation passage 60. The seat cushion S1 is configured so that air blown from the blower 110 passes through the duct 120 and the ventilation passage 60 and is blown out from the top surface of the seat cushion pad P1 towards the occupant.

[0122] The duct 120 has an L-shape when viewed from the left and right directions, extending forward from the blower 110, then bending and extending upward. The duct 120 extends from the lower side of the first pressure receiving member 30 through the through hole 351 to the upper side of the first pressure receiving member 30.

[0123] As shown in Figures 9(a) and (b), the duct 120 is positioned so as not to overlap with the mounting portion 380 when viewed from above. Specifically, the duct 120 is positioned so as not to overlap with any of the first mounting portion 380A, the second mounting portion 380B, and the third mounting portion 380C when viewed from above. The first mounting portion 380A is positioned in front of the duct 120 and the sensor 140. The duct 120 is positioned to the right of the center wire 32A. The duct 120 is positioned to the right of the left-right center of the first pressure receiving member 30.

[0124] The second end 122 of the duct 120, which is the connection point between the duct 120 and the ventilation passage 60 (see Figure 10), is positioned in the front-to-back direction to coincide with the sensor 140. Specifically, when viewed from above, the second end 122 of the duct 120 is positioned side-by-side with the sensor 140 in the left-to-right direction. When viewed from above, the second end 122 of the duct 120 is positioned to the right of the sensor 140.

[0125] Furthermore, the second end 122 of the duct 120 is positioned to the right of the left-right center of the first pressure receiving member 30. Also, when viewed from above, the second end 122 of the duct 120 is positioned between the horizontal wire 33 and the blower 110. When viewed from above, the second end 122 of the duct 120 is positioned closer to the horizontal wire 33 than to the blower 110.

[0126] As shown in Figure 6, the duct 120 and its second end 122 are positioned closer to the front end of the first side frame 11 than to the side frame cover 40 in the front-rear direction. In other words, the second end 122 of the duct 120 is positioned in front of the front end of the side frame cover 40 when viewed from above.

[0127] As shown in Figures 9(a) and (b), the ECU 130 is attached to the first pressure-receiving member 30. The ECU 130 is positioned so as not to overlap with the vertical wires 32 when viewed from above. Specifically, the ECU 130 is positioned so as not to overlap with the center wire 32A, the first side wire 32B, and the second side wire 32C when viewed from above. In addition, the ECU 130 is positioned so as not to overlap with the horizontal wires 33 when viewed from above.

[0128] The ECU130 is positioned to the left of the center wire 32A. Specifically, when viewed from above, the ECU130 is positioned between the center wire 32A and the second side wire 32C. The ECU130's position in the front-to-back direction overlaps with that of the blower 110. In other words, the blower 110 and the ECU130 are positioned side by side in the left-to-right direction.

[0129] Furthermore, as shown in Figure 5, the ECU 130 is positioned so that its front-to-back position coincides with the second bend 321E of the vertical wire 32. Alternatively, the ECU 130 may be positioned so that it coincides with the second bend 321E of the vertical wire 32 when viewed from the left-to-right direction. Also, the ECU 130 may be positioned so that it coincides with the first bend 321D of the vertical wire 32 when viewed from the left-to-right direction.

[0130] As shown in Figures 9(a) and (b), the sensor 140 is attached to the upper surface of the first pressure-receiving member 30, which is the side facing the seated person. Specifically, the sensor 140 is attached to the upper surface of the sensor mounting portion 340. The sensor 140 is positioned to the left of the center wire 32A. The sensor 140 is positioned to the left of the center in the left-right direction of the first pressure-receiving member 30. Specifically, the sensor 140 is positioned on the left portion of the sensor mounting portion 340 with respect to the center in the left-right direction of the first pressure-receiving member 30. More specifically, the sensor 140 is attached to the second sensor mounting portion 340B.

[0131] The sensor 140 is positioned so as not to overlap with the blower 110 when viewed from above. The sensor 140 does not overlap with the blower 110 in both the front-to-back and left-to-right directions. Specifically, the sensor 140 is positioned in front of the blower 110 and to the left of the blower 110 when viewed from above. The sensor 140 is positioned diagonally to the front left of the blower 110 when viewed from above.

[0132] The sensor 140 is positioned so as not to overlap with the duct 120 when viewed from above. Specifically, the sensor 140 is positioned to the left of the duct 120 when viewed from above. More precisely, the sensor 140 is positioned to the left of the second end 122 of the duct 120 when viewed from above. The duct 120 and the sensor 140 are positioned between the first side wire 32B and the second side wire 32C when viewed from above.

[0133] As shown in Figure 6, the sensor 140 is positioned closer to the front end of the first side frame 11 than to the side frame cover 40 in the front-rear direction. Specifically, when viewed from above, the sensor 140 is positioned in front of the front end of the side frame cover 40.

[0134] As shown in Figures 11 and 12, the first sensor mounting portion 340A and the second sensor mounting portion 340B each have a first clamping portion 341, a second clamping portion 342, a third clamping portion 343, and a recess 344, respectively.

[0135] As shown in Figure 13(a), the first clamping portion 341 clamps the sensor 140 when the sensor 140 is attached to the sensor mounting portion 340. The first clamping portion 341 has a first contact portion 341A and a second contact portion 341B located below the first contact portion 341A, and when the sensor 140 is attached to the sensor mounting portion 340, it clamps the sensor 140 between the first contact portion 341A and the second contact portion 341B.

[0136] When the sensor 140 is attached, the second contact portion 341B elastically bends downward at its inner end in the left-right direction. As a result, the second contact portion 341B pushes the sensor 140 from below, causing the sensor 140 to come into contact with the first contact portion 341A.

[0137] The vehicle seat S further includes a harness 141. The harness 141 is electrically connected to the sensor 140. For example, one end of the harness 141 is electrically connected to the sensor 140, and the other end (not shown) is electrically connected to the ECU 130 (see Figure 9). In the left-right direction, the harness 141 extends from the sensor 140 to the side opposite to the side where the first clamping portion 341 is located. In this embodiment, the harness 141 extends to the left from the sensor 140.

[0138] As shown in Figure 13(b), the second clamping portion 342 and the third clamping portion 343 clamp the sensor 140 when the sensor 140 is attached to the sensor mounting portion 340. The third clamping portion 343 is positioned side by side with the second clamping portion 342 in the front-rear direction. The third clamping portion 343 is positioned behind the second clamping portion 342. The second clamping portion 342 and the third clamping portion 343 are formed in a shape that is substantially symmetrical in the front-rear direction.

[0139] The second clamping portion 342 and the third clamping portion 343 each have a third contact portion 342A, 343A and a fourth contact portion 342B, 343B positioned below the third contact portion 342A, 343A. When the sensor 140 is attached to the sensor mounting portion 340, the second clamping portion 342 and the third clamping portion 343 clamp the sensor 140 between the third contact portion 342A, 343A and the fourth contact portion 342B, 343B.

[0140] The fourth contact portions 342B and 343B are protrusions that project upward from the bottom of the sensor mounting portion 340 (340A and 340B). As shown in Figure 12, the fourth contact portions 342B and 343B extend in the left-right direction. Having such fourth contact portions 342B and 343B improves the rigidity of the sensor mounting portion 340 (340A and 340B).

[0141] The first clamping portion 341 of the first sensor mounting portion 340A is positioned between the center of the first sensor mounting portion 340A and the center wire 32A in the left-right direction. The through hole 351 is positioned on the opposite side of the first clamping portion 341 from the center of the first sensor mounting portion 340A in the left-right direction. Specifically, with respect to the left-right center of the first sensor mounting portion 340A, the first clamping portion 341 is positioned to the left, and the through hole 351 is positioned to the right.

[0142] The second clamping portion 342 and the third clamping portion 343 of the first sensor mounting portion 340A are positioned to the right of the first clamping portion 341. The left-right positions of the second clamping portion 342 and the third clamping portion 343 of the first sensor mounting portion 340A coincide with the left-right center of the first sensor mounting portion 340A.

[0143] The first clamping portion 341 of the second sensor mounting portion 340B is positioned between the center of the second sensor mounting portion 340B and the center wire 32A in the left-right direction. The through hole 352 is positioned on the opposite side of the second sensor mounting portion 341 from the center of the second sensor mounting portion 340B in the left-right direction. Specifically, with respect to the left-right center of the second sensor mounting portion 340B, the first clamping portion 341 is positioned to the right, and the through hole 352 is positioned to the left.

[0144] The second clamping portion 342 and the third clamping portion 343 of the second sensor mounting portion 340B are positioned to the left of the first clamping portion 341. The left-right positions of the second clamping portion 342 and the third clamping portion 343 of the second sensor mounting portion 340B coincide with the left-right center of the second sensor mounting portion 340B.

[0145] The recess 344 has a shape that, in the left-right direction, is recessed from the edge of the sensor mounting portion 340 (340A, 340B) opposite to the side where the first clamping portion 341 is located toward the first clamping portion 341. Specifically, the recess 344 of the first sensor mounting portion 340A has a shape that is recessed from the right edge of the first sensor mounting portion 340A toward the left where the first clamping portion 341 is located. The recess 344 of the second sensor mounting portion 340B has a shape that is recessed from the left edge of the second sensor mounting portion 340B toward the right where the first clamping portion 341 is located. When viewed from above, the recess 344 has a V-shape.

[0146] The recess 344 of the first sensor mounting portion 340A is positioned side by side with the first clamping portion 341 in the left-right direction. The recess 344 of the first sensor mounting portion 340A is positioned to the right of the first clamping portion 341. In the front-rear direction, the recess 344 of the first sensor mounting portion 340A is located between the second clamping portion 342 and the third clamping portion 343.

[0147] The recess 344 of the second sensor mounting portion 340B is positioned side by side with the first clamping portion 341 in the left-right direction. The recess 344 of the second sensor mounting portion 340B is positioned to the left of the first clamping portion 341. In the front-rear direction, the recess 344 of the second sensor mounting portion 340B is located between the second clamping portion 342 and the third clamping portion 343.

[0148] The edges of the through holes 351 and 352 are thicker than the mesh portion 362 of the mesh portion 360 (360A, 360B) when viewed from above. The mesh portion 362 is the part that forms the mesh of the mesh portion 360. Multiple mesh portions 362 are provided. When viewed from above, the multiple mesh portions 362 extend in the front-rear direction or in a direction intersecting the front-rear direction, forming the mesh of the mesh portion 360. The thickened portion 361 (see Figure 4) is part of the mesh portion 362. When viewed from above, the front edges 351A, 352A, the outer edges 351B, 352B on the left-right side, and the rear edge, which is the fourth frame portion 374, are thicker than the mesh portion 362 of the through holes 351 and 352.

[0149] Some of the multiple mesh sections 362 are connected to the edges of the through holes 351 and 352. More specifically, the mesh section 362 includes mesh sections 362A to 362D that extend in the front-rear direction, and mesh sections 362E to 362G that extend intersecting the mesh sections 362A to 362D. The front ends of each of the mesh sections 362A to 362G are connected to the fourth frame section 374, which is the rear edge of the through holes 351 and 352.

[0150] Next, a method for manufacturing the vehicle seat S according to the embodiment will be described. The method for manufacturing the vehicle seat S includes a duct arrangement step and a sensor mounting step.

[0151] The duct placement process involves positioning the duct 120 on one side in the left-right direction relative to the center wire 32A. Specifically, the duct 120 is positioned to the right of the center wire 32A. The first end 121 (see Figure 10) of the duct 120 is connected to the outlet 113A of the blower 110. In the duct placement process, the duct 120 may or may not be fixed to the first pressure receiving member 30.

[0152] In the sensor mounting process, the sensor 140 is slid in the left-right direction toward the center wire 32A from the other side in the left-right direction, engaging with the second clamping portion 342, the third clamping portion 343, and the first clamping portion 341. Specifically, the sensor 140 (see thin dashed line) is slid from left to right of the second sensor mounting portion 340B toward the center wire 32A, engaging with the second clamping portion 342, the third clamping portion 343, and the first clamping portion 341 of the second sensor mounting portion 340B.

[0153] Next, the effects of the vehicle seat S according to the first embodiment will be described. Since the duct 120 is positioned on the right, which is one side in the left-right direction relative to the center wire 32A, and the sensor 140 is positioned on the left, which is the other side in the left-right direction relative to the center wire 32A, interference between the duct 120 and the sensor 140 can be suppressed.

[0154] Since the duct 120 is positioned to the right of the left-right center of the first pressure-receiving member 30, and the sensor 140 is positioned to the left of the left-right center of the first pressure-receiving member 30, interference between the duct 120 and the sensor 140 can be suppressed.

[0155] The duct 120 and sensor 140 are positioned between the first side wire 32B and the second side wire 32C when viewed from above, so that the duct 120 and sensor 140 can be protected by the first side wire 32B and the second side wire 32C.

[0156] In the left-right direction, the first clamping portion 341 of the first sensor mounting portion 340A is positioned between the center of the first sensor mounting portion 340A and the center wire 32A, and the first clamping portion 341 of the second sensor mounting portion 340B is positioned between the center of the second sensor mounting portion 340B and the center wire 32A. This allows the first clamping portion 341 to be positioned close to the center wire 32A. As a result, the rigidity of the first clamping portion 341 can be improved by the center wire 32A.

[0157] Since the first sensor mounting portion 340A and the second sensor mounting portion 340B each have a first clamping portion 341, a second clamping portion 342, and a third clamping portion 343, respectively, when the sensor 140 is attached, the sensor 140 can be firmly attached to the first pressure receiving member 30.

[0158] In the left-right direction, the through hole 351 is positioned on the opposite side of the first clamping portion 341 from the center of the first sensor mounting portion 340A, and the through hole 352 is positioned on the opposite side of the first clamping portion 341 from the center of the second sensor mounting portion 340B. Therefore, when the duct 120 is passed through, the first clamping portion 341 and the duct 120 can be positioned apart. This suppresses interference between the first clamping portion 341 and the duct 120.

[0159] The harness 141 extends in the left-right direction from the sensor 140 to the side opposite to the side where the first clamping portion 341 is located, thereby suppressing interference between the harness 141 and the first clamping portion 341.

[0160] Since the first sensor mounting portion 340A and the second sensor mounting portion 340B each have recesses 344, interference between the harness 141 and the sensor mounting portion 340 (340A, 340B) can be suppressed when the sensor 140 to which the harness 141 is connected is mounted.

[0161] The resin member 31 covering the center wire 32A is made of elastomer, which improves the seating comfort of the vehicle seat S.

[0162] The front edges 351A, 352A, outer edges 351B, 352B, and rear edge (fourth frame portion 374) of the through holes 351, 352 of the first pressure receiving member 30 are thicker than the mesh portion 362 of the mesh portion 360 when viewed from above, making it difficult for the through holes 351, 352 to deform. This suppresses interference between the edge of the through hole 351 and the duct 120 passed through the through hole 351.

[0163] The mesh portions 362A to 362G of the first pressure-receiving member 30 are connected to the edges (fourth frame portion 374) of the through holes 351 and 352, making the through holes 351 and 352 less susceptible to deformation. This further reduces interference between the edge of the through hole 351 and the duct 120.

[0164] By positioning the first mounting portion 380A in front of the duct 120 and sensor 140, interference between the member attached to the first mounting portion 380A and the duct 120 and sensor 140 can be suppressed.

[0165] By sliding the sensor 140 from the side opposite to the side where the duct 120 is located toward the center wire 32A and engaging it with the second clamping portion 342, the third clamping portion 343, and the first clamping portion 341, interference between the sensor 140 and the duct 120 can be suppressed when installing the sensor 140. The duct 120 does not get in the way when installing the sensor 140.

[0166] Since the first pressure-receiving member 30 includes an elastic resin member 31 and the blower 110 is attached to the resin member 31, vibrations when the blower 110 is operating can be suppressed.

[0167] Because the first pressure-receiving member 30 is plate-shaped, the blower 110 is easy to attach to the first pressure-receiving member 30.

[0168] Since the resin member 31 to which the blower 110 is attached is made of elastomer, vibrations when the blower 110 is operating can be effectively suppressed.

[0169] The blower 110 is positioned so that, when viewed from above, it does not overlap with the mounting section 380. This makes it less likely for the blower 110 to get in the way when attaching other components, such as harnesses, to the mounting section 380.

[0170] Since the duct 120 is positioned so that it does not overlap with the mounting part 380 when viewed from above, the duct 120 is less likely to get in the way when attaching components other than the blower 110, such as harnesses, to the mounting part 380.

[0171] Since the duct 120 extends upward from the lower side of the first pressure-receiving member 30 through the through-hole 351 of the first pressure-receiving member 30, the duct 120 can be arranged more compactly compared to, for example, a case where the duct extends upward through the front, back, left, and right sides of the first pressure-receiving member.

[0172] The position of the second end 122 of the duct 120 in the front-rear direction is closer to the front end of the first side frame 11 than to the side frame cover 40, allowing the second end 122 of the duct 120 to be positioned away from the side frame cover 40.

[0173] The position of the blower 110 in the front-to-back direction coincides with that of the side frame cover 40, allowing the blower 110 to be positioned within the width of the side frame cover 40 in the front-to-back direction.

[0174] Since the blower 110 is directly attached to the resin member 31, the number of parts can be reduced compared to, for example, when the blower is attached to the resin member via a bracket or the like.

[0175] Since the sensor 140 is mounted on the upper surface of the first pressure-receiving member 30 and the blower 110 is mounted on the lower surface of the first pressure-receiving member 30, the sensor 140 and the blower 110 can be arranged more compactly compared to, for example, the case where both the sensor and the blower are mounted on the same upper and lower sides of the first pressure-receiving member.

[0176] To elaborate, if both the sensor and the blower are mounted on the same upper and lower side of the first pressure-receiving member, the blower must be positioned a certain distance from the sensor so as not to interfere with the sensor's detection, making it difficult to arrange the sensor and blower compactly. In the first embodiment, even if the blower 110 is positioned close to the sensor 140, it does not interfere with the sensor 140's detection. This allows the sensor 140 and blower 110 to be arranged compactly.

[0177] The position of the second end 122 of the duct 120 in the front-to-back direction coincides with that of the sensor 140, allowing the sensor 140 and the second end 122 of the duct 120 to be compactly arranged in the front-to-back direction.

[0178] With respect to the left-right center of the first pressure-receiving member 30, the second end 122 of the duct 120 is positioned to the right, and the sensor 140 is positioned to the left. This allows for a reduction in the size of the first pressure-receiving member 30 compared to, for example, a case where the connection portion of the duct to the air passage and the sensor are positioned on the same left and right sides.

[0179] By positioning the sensor 140 in a location that does not overlap with the duct 120 when viewed from above, the duct 120 can be made shorter. Furthermore, the duct 120 can be made into a simpler shape.

[0180] Since the sensor 140 is positioned so as not to overlap with the blower 110 when viewed from above, vibrations from the blower 110 when it is operating are less likely to affect the detection of the sensor 140.

[0181] Since the position of the sensor 140 in the left-right direction does not overlap with the blower 110, the sensor 140 can be positioned further away from the blower 110.

[0182] The position of the blower 110 in the front-rear direction overlaps with the side frame cover 40, and the position of the sensor 140 in the front-rear direction is closer to the front end of the first side frame 11 than the side frame cover 40, allowing the sensor 140 to be positioned further away from the blower 110.

[0183] By positioning the blower 110 in a location that does not overlap with the vertical wire 32 when viewed from above, the blower 110 can be positioned to overlap with the vertical wire 32 in the vertical direction, which is the direction in which the first pressure receiving member 30 faces the seated person. This allows the first pressure receiving member 30 and the blower 110 to be arranged compactly in the vertical direction.

[0184] The position of the blower 110 in the front-to-back direction coincides with the bent portions 321D and 321E of the vertical wire 32, allowing the blower 110 to be mounted near the highly rigid bent portions 321D and 321E of the vertical wire 32. This improves the mounting strength of the blower 110.

[0185] The position of the ECU130 in the front-to-back direction coincides with the second bend 321E of the vertical wire 32, allowing the ECU130 to be mounted near the highly rigid second bend 321E of the vertical wire 32. This improves the mounting strength of the ECU130.

[0186] By positioning the ECU130 in a location that does not overlap with the vertical wire 32 when viewed from above, the ECU130 can be positioned to overlap with the vertical wire 32 in the vertical direction. This allows the first pressure-receiving member 30 and the ECU130 to be arranged compactly in the vertical direction.

[0187] The blower 110 is positioned between the center wire 32A and the first side wire 32B when viewed from above, allowing the blower 110 to be attached to the portion of the first pressure receiving member 30 that is reinforced by the center wire 32A and the first side wire 32B, between the center wire 32A and the first side wire 32B. This improves the mounting strength of the blower 110.

[0188] The second end 122 of the duct 120 is positioned closer to the lateral wire 33 than to the blower 110 when viewed from above, allowing the second end 122 of the duct 120 to be positioned near the portion of the first pressure-receiving member 30 that is reinforced by the lateral wire 33.

[0189] With respect to the center wire 32A, the blower 110 is positioned to the right and the ECU 130 is positioned to the left. This makes it easier to secure mounting locations for the blower 110 and the ECU 130 compared to, for example, a case where the blower and the control device are positioned on the same side.

[0190] The blower 110 is positioned between the center wire 32A and the first side wire 32B when viewed from above, allowing the blower 110 to be attached to the portion of the first pressure receiving member 30 that is reinforced by the center wire 32A and the first side wire 32B, between the center wire 32A and the first side wire 32B. Similarly, the ECU 130 is positioned between the center wire 32A and the second side wire 32C when viewed from above, allowing the ECU 130 to be attached to the portion of the first pressure receiving member 30 that is reinforced by the center wire 32A and the second side wire 32C, between the center wire 32A and the second side wire 32C. This improves the mounting strength of the blower 110 and the ECU 130.

[0191] Since the transverse wire 33 passes through the leading edges 351A and 352A of the through holes 351 and 352 in the resin member 31, the transverse wire 33 can reinforce the edges of the through holes 351 and 352 in the resin member 31.

[0192] The resin member 31 having a mesh portion 360 improves the cushioning properties of the first pressure-receiving member 30. Furthermore, it allows for a reduction in the weight of the first pressure-receiving member 30.

[0193] The presence of a thickened portion 361 around the blower mounting portion 390 improves the strength of the blower mounting portion 390, thereby improving the mounting strength of the blower 110. Furthermore, the presence of a thickened portion 361 around the blower mounting portion 390 allows for a relatively smaller upward protrusion of the engaging portion 152 that engages with the blower mounting portion 390.

[0194] The tip of the engaging portion 152, which engages with the blower mounting portion 390, protrudes below the blower mounting portion 390, thereby reducing the amount of upward protrusion of the mounting member 150.

[0195] Since the thickened portion 361 protrudes above the mounting member 150, the mounting member 150 can be prevented from protruding above the thickened portion 361.

[0196] The first mounting portion 114A of the blower 110 is positioned in contact with the thick portion 361B and the thick portion 361C, thereby suppressing rattle of the first mounting portion 114A. The second mounting portion 114B of the blower 110 is positioned in contact with the thick portion 361D and the thick portion 361E, thereby suppressing rattle of the second mounting portion 114B. As a result, rattle of the blower 110 can be suppressed.

[0197] Since the blower mounting section 390 is provided to the right of the left-right center of the first pressure receiving member 30, the blower 110 can be positioned to the right of the left-right center of the first pressure receiving member 30, and space can be secured to the left for mounting a component other than the blower 110, such as an ECU 130.

[0198] The first pressure-receiving member 30 has a mesh portion 360 on which a blower mounting portion 390 is provided, thereby allowing the first pressure-receiving member 30 to have a blower mounting portion 390 while improving the cushioning properties of the first pressure-receiving member 30 with the mesh portion 360.

[0199] Since the blower mounting portion 390 is provided in contact with the frame portion 370 surrounding the mesh portion 360, the strength of the blower mounting portion 390 is further improved, and thus the mounting strength of the blower 110 can be further improved.

[0200] Next, a modified example of the first embodiment will be described. As shown in Figures 14(a) and (b), the blower 110 may have a configuration that includes protrusions 116A and 116B that project from the mounting portion 114 toward the blower mounting portion 390. For example, as shown in Figure 14(a), the protrusion 116A can have a rectangular prism shape or a cylindrical shape. The protrusion 116A may also be trapezoidal.

[0201] Furthermore, as shown in Figure 14(b), the protrusions 116B may have a rib shape extending in the front-to-back direction and be configured in a configuration where multiple protrusions are arranged in the front-to-back direction.

[0202] The protrusions 116A and 116B contact the blower mounting portion 390 from below when the engaging portion 152 of the mounting member 150 is engaged with the first through hole 391 of the blower mounting portion 390 and the second through hole 115 of the mounting portion 114. The mounting portion 114 is positioned in contact with the thickened portions 361B, 361C or 361D, 361E, and furthermore, the blower 110 has protrusions 116A and 116B that contact the blower mounting portion 390, so that rattling of the mounting portion 114 can be further suppressed by the thickened portions 361B, 361C or 361D, 361E and the protrusions 116A and 116B. As a result, rattling of the blower 110 can be further suppressed.

[0203] Next, a second embodiment will be described. The following description will focus on the differences from the previously described embodiment. Points that are the same as those described in the previously described embodiment will be omitted from the description by using the same reference numerals for the same elements.

[0204] As shown in Figures 15 and 16(a) and (b), in the second embodiment, the blower 110 is attached to the lower side of the sensor mounting portion 340 provided on the resin member 31 of the first pressure receiving member 30. The blower 110 is directly attached to the resin member 31. For example, the blower 110 has a plate-shaped mounting portion and is fixed to the resin member 31 by screws, rivets, or the like.

[0205] The blower 110 is positioned in the left-right center of the first pressure receiving member 30. When viewed from above, the blower 110 is positioned so as to overlap with the center wire 32A. When viewed from above, the blower 110 is positioned so as not to overlap with the first side wire 32B and the second side wire 32C. When viewed from above, the blower 110 is positioned so as to overlap with the horizontal wire 33.

[0206] The blower 110 is positioned closer to the front end of the first side frame 11 than to the side frame cover 40 in the front-rear direction. Specifically, when viewed from above, the blower 110 is positioned in front of the front end of the side frame cover 40.

[0207] The blower 110 is positioned so that its front-to-back orientation coincides with the through-holes 351 and 352. Specifically, when viewed from above, the blower 110 is located to the left of through-hole 351. Also, when viewed from above, the blower 110 is located to the right of through-hole 352. In other words, when viewed from above, the blower 110 is located between through-holes 351 and 352.

[0208] The blower 110 is positioned so that it overlaps with the sensor 140 when viewed from above. In other words, the sensor 140 is positioned so that it overlaps with the blower 110 when viewed from above. The position of the sensor 140 in the front-to-back direction overlaps with the blower 110. Also, the position of the sensor 140 in the left-to-right direction overlaps with the blower 110. The sensor 140 is positioned above the blower 110. The blower 110 and the sensor 140 are positioned opposite each other in the vertical direction, with the sensor mounting portion 340 in between.

[0209] In the second embodiment, the duct 120 extends to the right from the blower 110, then bends and extends upward. The duct 120 extends from the lower side of the first pressure receiving member 30 through the through hole 351 to the upper side of the first pressure receiving member 30.

[0210] The duct 120 is positioned so as not to overlap with the mounting portion 380 when viewed from above. Specifically, the duct 120 is positioned so as not to overlap with any of the first mounting portion 380A, the second mounting portion 380B, and the third mounting portion 380C when viewed from above.

[0211] In the second embodiment, the ECU 130 is attached to a mounting portion 380 provided on the first pressure-receiving member 30. Specifically, the ECU 130 is attached to a third mounting portion 380C provided on the left side support portion 312. For example, the ECU 130 is attached to the first pressure-receiving member 30 by engaging a clip, a claw portion provided on the ECU 130 itself, etc., with a mounting hole 381.

[0212] ECU130 is positioned so as not to overlap with the center wire 32A and the first side wire 32B when viewed from above. ECU130 is positioned to the left of the center wire 32A. ECU130 is positioned so as to overlap with the second side wire 32C when viewed from above.

[0213] Next, the effects of the vehicle seat S according to the second embodiment will be described. By aligning the front-to-back position of the blower 110 with the through-hole 351 of the first pressure-receiving member 30, the distance from the blower 110 to the through-hole 351 can be shortened. This allows the duct 120 to be shortened.

[0214] The position of the blower 110 in the front-rear direction is closer to the front end of the first side frame 11 than to the side frame cover 40, allowing the blower 110 to be positioned away from the side frame cover 40.

[0215] By positioning the sensor 140 so that it overlaps with the blower 110 when viewed from above, the sensor 140 and the blower 110 can be arranged more compactly.

[0216] The first and second embodiments have been described above, but the vehicle seat can be modified as appropriate as shown below.

[0217] In the above embodiment, the vehicle seat S was configured to include a mounting member 150 having an engaging portion 152. However, for example, the vehicle seat S may not include the mounting member 150, and the blower 110 may be configured to have an engaging portion 117, as shown in the first modified example in Figures 17(a) and (b). In the first modified example, the blower 110 is attached to the first pressure receiving member 30 by the engaging portion 117 engaging with the mounting hole 381 of the second mounting portion 380B from below. Since the blower 110 has an engaging portion 117, a mounting member having an engaging portion is unnecessary, thus reducing the number of parts.

[0218] The second mounting section 380B has a bottom wall 382 with a mounting hole 381 and a side wall 383 that protrudes upward from around the bottom wall 382. The upper end of the side wall 383 is connected to the mesh section 362 of the mesh section 360 (360A, 360B). In the first modified example, the bottom wall 382 corresponds to the "blower mounting section," and the mounting hole 381 corresponds to the "first through hole." Also, the side wall 383 and the mesh section 362 correspond to the "thickened section."

[0219] In the first modification, the side wall 383 and mesh portion 362, which are thickened sections, are provided around the entire circumference of the bottom wall 382, ​​rather than just on a portion of its periphery. In other words, in the first modification, the bottom wall 382, ​​which serves as the blower mounting section, is not in contact with the frame portion 370 (371-375). Also, in the first modification, the side wall 383 and mesh portion 362, which are thickened sections, protrude only above the bottom wall 382, ​​and not below it.

[0220] The tip of the engaging portion 117 protrudes above the bottom wall 382. Of the side walls 383 and mesh portion 362 that constitute the thickened portion, the mesh portion 362 protrudes above the engaging portion 117. Specifically, the mesh portion 362 protrudes above the tip of the engaging portion 117. In other words, the engaging portion 117 does not protrude above the mesh portion 362.

[0221] As shown in the second modified example in Figures 18(a) and (b), the vehicle seat S may be configured such that the first pressure-receiving member 30 has an engaging portion 384. Specifically, the engaging portion 384 protrudes downward from the resin member 31. In the second modified example, the blower 110 is attached to the first pressure-receiving member 30 by the engaging portion 384 engaging from above with the second through-hole 115 of the mounting portion 114 provided on the blower 110. Since the first pressure-receiving member 30 has an engaging portion 384, a mounting member with an engaging portion is not required, thus reducing the number of parts.

[0222] The engaging portion 384 may have a mounting hole 385 that penetrates vertically at its tip. A component other than the blower 110 can be attached to the mounting hole 385. For example, a harness can be attached to the first pressure receiving member 30 by engaging a harness clip 70 for holding the harness with the mounting hole 385.

[0223] As shown in the third modified example in Figure 19, the vehicle seat S may be configured to include a seat cushion airbag 160. The seat cushion airbag 160 inflates during a collision to suppress the so-called submarining phenomenon, in which the occupant slides off the seat cushion S1 and into the space under their feet. The seat cushion airbag 160 is positioned on top of the pan frame 14.

[0224] The blower 110, duct 120, ECU 130, and sensor 140 are each positioned so as not to overlap with the seat cushion airbag 160 in its uninflated state when viewed from above. Specifically, the blower 110, duct 120, ECU 130, and sensor 140 are each positioned behind the seat cushion airbag 160 in its uninflated state when viewed from above.

[0225] Furthermore, the second end 122 of the duct 120 is positioned so as not to overlap with the seat cushion airbag 160 when viewed from above. Specifically, the second end 122 of the duct 120 is positioned behind the seat cushion airbag 160 in its uninflated state when viewed from above.

[0226] As shown in Figures 20(a) and (b), the vehicle seat S may be configured to include vibration generating devices 171 and 172 that generate vibrations. For example, as in the fourth modified example shown in Figure 20(a), the vibration generating device 171 includes two eccentric motors 171A. The eccentric motors 171A are arranged, for example, one each in the left and right recesses formed in the front part of the first central part PC1 of the seat cushion pad P1.

[0227] The blower 110, duct 120, ECU 130, and sensor 140 are each positioned so as not to overlap with the eccentric motor 171A when viewed from above. Specifically, the blower 110, duct 120, ECU 130, and sensor 140 are each positioned behind the eccentric motor 171A when viewed from above.

[0228] Furthermore, as shown in the fifth modified example in Figure 20(b), the vibration generating device 172 comprises a rod-shaped vibration transmitting member 172A and a vibration output device 172B that outputs vibrations to the vibration transmitting member 172A. The vibration transmitting member 172A is located within the seat cushion pad P1.

[0229] The blower 110, duct 120, ECU 130, and sensor 140 are each positioned so as not to overlap with the vibration transmission member 172A when viewed from above. The blower 110, duct 120, and ECU 130 are each positioned behind the rear end of the vibration transmission member 172A when viewed from above. The sensor 140 is positioned between the rear ends of the two vibration transmission members 172A when viewed from above.

[0230] As shown in Figures 21(a) and (b), the vehicle seat S may be configured to include a plurality of air bladders 181, 182. In a vehicle seat S equipped with air bladders 181, 182, the support position for the occupant can be changed, for example, by adjusting the amount of air in the air bladders 181, 182. In addition, in a vehicle seat S equipped with air bladders 181, 182, the repeated inflation and deflation of the air bladders 181, 182 can provide the occupant with a massage effect, an alerting effect, etc.

[0231] As shown in the sixth modified example in Figure 21(a), multiple air bladders 181 are arranged between the first central part PC1 of the seat cushion pad P1 and the seat cushion surface SK1. Specifically, the air bladders 181 include a first air bladder 181A, a second air bladder 181B positioned behind the first air bladder 181A, and a third air bladder 181C positioned behind the second air bladder 181B.

[0232] The first air bag 181A and the second air bag 181B are positioned so as to sandwich the sensor mounting portion 340 and the through holes 351 and 352 from the front and back when viewed from above. The second end 122 of the duct 120 and the sensor 140 are positioned so as not to overlap with the air bag 181 when viewed from above. Specifically, the second end 122 of the duct 120 and the sensor 140 are positioned so as not to overlap with the air bag 181 when viewed from above. The blower 110 may also be positioned so as not to overlap with the air bag 181 when viewed from above. The duct 120 may also be positioned so as not to overlap with the air bag 181 when viewed from above. The ECU 130 may also be positioned so as not to overlap with the air bag 181 when viewed from above.

[0233] Furthermore, as shown in the seventh modified example in Figure 21(b), the air bladder 182 is positioned between each first side PS1 of the seat cushion pad P1 and the seat cushion surface SK1. Specifically, the air bladder 182 includes a right air bladder 182A positioned on the right first side PS1 and a left air bladder 182B positioned on the left first side PS1.

[0234] The blower 110, duct 120, ECU 130, and sensor 140 are each positioned so as not to overlap with the air bag 182 when viewed from above. Specifically, the blower 110, duct 120, ECU 130, and sensor 140 are each positioned between the right air bag 182A and the left air bag 182B when viewed from above.

[0235] Furthermore, the second end 122 of the duct 120 and the sensor 140 are positioned so as not to overlap with the air bag 182 when viewed from above. Specifically, the second end 122 of the duct 120 and the sensor 140 are positioned between the right air bag 182A and the left air bag 182B when viewed from above.

[0236] In the above embodiment, a vertical wire 32 stretched between the front frame 12 and the rear frame 13 was exemplified as the first reinforcing wire, but the first reinforcing wire may be a wire stretched between the left and right first side frames 11. As an example, as shown in the eighth modified example in Figure 22, the horizontal wire 33 as the first reinforcing wire includes a front wire 33A and a rear wire 33B.

[0237] The front wire 33A and the rear wire 33B each extend in the left-right direction, with their right ends engaging with the right first side frame 11 and their left ends engaging with the left first side frame 11. The left-right central portion of both the front wire 33A and the rear wire 33B is covered by a resin member 31. The left and right ends of the front wire 33A and the rear wire 33B may also be covered with resin or the like.

[0238] The blower 110, duct 120, ECU 130, and sensor 140 are each positioned so as not to overlap with the horizontal wire 33 when viewed from above. Specifically, the blower 110, duct 120, ECU 130, and sensor 140 are each positioned between the front wire 33A and the rear wire 33B when viewed from above.

[0239] In a configuration where the horizontal wire 33 is stretched across the left and right first side frames 11, the vertical wire 32 (a wire extending in the front-to-back direction) may not be stretched across the front frame 12 and the rear frame 13. Also, the first pressure receiving member may not have a wire extending in the front-to-back direction.

[0240] In the above embodiment, the ECU 130 was attached to the first pressure-receiving member 30, but the ECU 130 may be attached to a member other than the first pressure-receiving member 30. For example, the ECU 130 may be attached to the seat frame F, such as the first side frame 11.

[0241] Furthermore, as shown in the ninth modified example in Figures 23(a) and (b), the vehicle seat S may include a support member 190 mounted across the left and right upper rails R2, and the ECU 130 may be attached to the support member 190. The support member 190 is made of, for example, a metal plate or resin. The ECU 130 is attached, for example, to the upper surface of the support member 190. The seat cushion S1, the support member 190, and the ECU 130 are slidable back and forth together with the upper rails R2.

[0242] In the ninth modification, the blower 110 is attached to the first pressure receiving member 30, similar to the first embodiment. In the ninth modification, as shown in Figure 23(a), the blower 110 and duct 120 are positioned so as not to overlap with the ECU 130 when viewed from above. In this configuration, the blower 110 and duct 120 and the ECU 130 can be positioned so that their vertical positions overlap, making the vehicle seat S more compact in the vertical direction. The sensor 140 is positioned so as to overlap with the ECU 130 when viewed from above. The sensor 140 is located on the upper surface of the sensor mounting portion 340, and the ECU 130 is located below the sensor mounting portion 340.

[0243] In the tenth modified example shown in Figure 24, the blower 110 is attached to the first pressure receiving member 30, similar to the second embodiment, and the ECU 130 is attached to the support member 190, similar to the ninth modified example (see Figure 23(b)). In the tenth modified example, the blower 110 is positioned so as to overlap with the ECU 130 when viewed from above. Specifically, the blower 110 is positioned above the ECU 130. With this configuration, the wiring connecting the blower 110 and the ECU 130 can be shortened.

[0244] In the above embodiment, the blower mounting portion 390 was provided on the mesh portion 360 of the first pressure receiving member 30. However, for example, the blower mounting portion may be provided on a part of the first pressure receiving member other than the mesh portion, such as a side support portion, a sensor mounting portion, or a frame portion.

[0245] Next, a third embodiment will be described. Patent Document 1 discloses a vehicle seat comprising a frame having left and right side frames, a support panel positioned between the left and right side frames, and a seat pad. The seat pad has a plurality of ventilation passages formed therein. The ventilation passages are formed to penetrate the back and front sides of the seat pad.

[0246] By the way, the areas where ventilation channels are formed in the pad will have reduced cushioning. Therefore, it is desirable to be able to support the reduction in cushioning in the areas where ventilation channels are formed in the pad.

[0247] As shown in Figure 25, the vehicle seat S of the third embodiment comprises a seat frame F, a first pressure-receiving member 30, and a seat cushion pad P1 (see Figure 26) that covers the seat frame F and the first pressure-receiving member 30.

[0248] The vertical wires 32 of the first pressure-receiving member 30 include a center wire 32A as the first vertical wire, a first side wire 32B as the second vertical wire, a second side wire 32C as the third vertical wire, a third side wire 32D as the fourth vertical wire, and a fourth side wire 32E as the fifth vertical wire.

[0249] The third side wire 32D is positioned between the center wire 32A and the first side wire 32B. In the front-rear direction, the third side wire 32D extends from near the front edge 351A of the through hole 351 to near the fifth frame portion 375 of the frame portion 370. The fourth side wire 32E is positioned between the center wire 32A and the second side wire 32C. In the front-rear direction, the fourth side wire 32E extends from near the front edge 352A of the through hole 352 to near the fifth frame portion 375.

[0250] The transverse wire 33 includes a first transverse wire 331 and a second transverse wire 332. The first transverse wire 331 passes through the leading edges 351A and 352A of the through holes 351 and 352. The second transverse wire 332 is positioned alongside the first transverse wire 331 in the front-rear direction. The second transverse wire 332 is positioned behind the first transverse wire 331. In the front-rear direction, the second transverse wire 332 is positioned between the rear edge (fourth frame portion 374) of the through holes 351, 352 and the second mounting portion 380B.

[0251] The first pressure-receiving member 30 is integrally molded by insert molding or the like, with the resin member 31 covering the center wire 32A, first side wire 32B, second side wire 32C, third side wire 32D, fourth side wire 32E, first transverse wire 331, and second transverse wire 332. The center wire 32A, first side wire 32B, second side wire 32C, third side wire 32D, fourth side wire 32E, first transverse wire 331, and second transverse wire 332 are arranged inside the resin member 31.

[0252] The blower 110 is positioned below the rear end of the second mesh section 360B. The duct 120 extends from the lower side of the first pressure-receiving member 30 through the through hole 352 to the upper side of the first pressure-receiving member 30. The sensor 140 is attached to the first sensor mounting portion 340A. In the third embodiment, the blower 110 and duct 120 are positioned to the left of the center wire 32A, and the sensor 140 is positioned to the right of the center wire 32A.

[0253] As shown in Figure 26, the seat cushion pad P1 has an internal ventilation passage 60. The ventilation passage 60 has a plurality of ventilation holes 65. The ventilation holes 65 extend in the vertical direction and open on the upper surface of the seat cushion pad P1.

[0254] As shown in Figure 27(a), the seat cushion pad P1 has ventilation grooves 64 on its lower surface. The ventilation grooves 64 are grooves that are recessed upwards. The vehicle seat S further includes a back cover 80. The back cover 80 is a plate-shaped member that covers the lower surface of the seat cushion pad P1. In the third embodiment, the back cover 80 is a relatively thin, cloth-like member. As shown in Figure 27(b), a portion of the ventilation passage 60 is formed by the ventilation grooves 64 being covered by the back cover 80. In the third embodiment, the portion of the ventilation passage 60 that extends in the front-rear or left-right direction, excluding the ventilation holes 65, is formed by the ventilation grooves 64 being covered by the back cover 80.

[0255] As shown in Figure 26, the ventilation grooves 64 forming the ventilation passage 60 include a first ventilation groove 64A, a second ventilation groove 64B, a third ventilation groove 64C, a fourth ventilation groove 64D, and a fifth ventilation groove 64E. The first ventilation groove 64A extends in the left-right direction. The second ventilation groove 64B extends backward from near the right end of the first ventilation groove 64A. The third ventilation groove 64C extends backward from near the left end of the first ventilation groove 64A. The fourth ventilation groove 64D extends forward from the right end of the first ventilation groove 64A. The fifth ventilation groove 64E extends forward from the left end of the first ventilation groove 64A. The ventilation holes 65 are arranged in a front-to-back direction along the second ventilation groove 64B, the third ventilation groove 64C, the fourth ventilation groove 64D, or the fifth ventilation groove 64E.

[0256] When viewed from above, the ventilation passage 60 overlaps with the mesh section 360. More specifically, when viewed from above, the second ventilation groove 64B overlaps with the first mesh section 360A. When viewed from above, the third ventilation groove 64C overlaps with the second mesh section 360B.

[0257] The vertical wire 32 overlaps with the ventilation passage 60 when viewed from above. More specifically, the front end of the first side wire 32B overlaps with the rear end of the fourth ventilation groove 64D when viewed from above. The front end of the second side wire 32C overlaps with the rear end of the fifth ventilation groove 64E when viewed from above. The third side wire 32D overlaps with the second ventilation groove 64B when viewed from above. The fourth side wire 32E overlaps with the third ventilation groove 64C when viewed from above.

[0258] When viewed from above, the horizontal wire 33 overlaps with the ventilation passage 60. More specifically, when viewed from above, the first horizontal wire 331 overlaps with the first ventilation groove 64A.

[0259] Viewed from above, the overlapping portion of the vertical wire 32 and the horizontal wire 33 coincides with the ventilation hole 65. More specifically, the overlapping portion L1 of the third side wire 32D and the first horizontal wire 331 coincides with the ventilation hole 65A. The overlapping portion L2 of the fourth side wire 32E and the first horizontal wire 331 coincides with the ventilation hole 65B. The overlapping portion L3 of the third side wire 32D and the second horizontal wire 332 coincides with the ventilation hole 65C. The overlapping portion L4 of the fourth side wire 32E and the second horizontal wire 332 coincides with the ventilation hole 65D.

[0260] The ventilation holes 65A, 65C, and 65E located on the second ventilation groove 64B overlap with the third side wire 32D when viewed from above. The ventilation holes 65B, 65D, and 65F located on the third ventilation groove 64C overlap with the fourth side wire 32E when viewed from above.

[0261] When viewed from above, the sensor 140 does not overlap with the ventilation passage 60. When viewed from above, the sensor 140 is positioned between the second ventilation groove 64B and the third ventilation groove 64C. When viewed from above, the sensor 140 is positioned adjacent to the rear of the first ventilation groove 64A. The sensor 140 is positioned below the seat cushion pad P1. The sensor 140 is positioned on the first sensor mounting portion 340A of the first pressure receiving member 30. In other words, the sensor 140 is positioned between the seat cushion pad P1 and the first sensor mounting portion 340A.

[0262] As shown in Figure 28, the seat cushion pad P1 further has a suspension groove 90 on its upper surface. The suspension groove 90 is a groove for suspending the seat cushion surface SK1 (see Figure 27(b)) onto the seat cushion pad P1.

[0263] The suspension groove 90 includes a first suspension groove 91, a second suspension groove 92, a third suspension groove 93, a fourth suspension groove 94, a fifth suspension groove 95, and a sixth suspension groove 96. The first suspension groove 91 and the second suspension groove 92 extend in the front-to-back direction. The first suspension groove 91 and the second suspension groove 92 are arranged side by side in the left-to-right direction.

[0264] The third suspension groove 93 extends to connect the front ends of the first suspension groove 91 and the second suspension groove 92. The third suspension groove 93 has a U-shape that is curved so as to be convex towards the front. The fourth suspension groove 94 extends in the left-right direction to connect the rear ends of the first suspension groove 91 and the second suspension groove 92. The fourth suspension groove 94 is located behind the third suspension groove 93.

[0265] The ventilation holes 65A to 65F are located inside the area enclosed by the first suspension groove 91, the second suspension groove 92, the third suspension groove 93, and the fourth suspension groove 94, when viewed from above.

[0266] The fifth hanging groove 95 and the sixth hanging groove 96 extend forward from the third hanging groove 93. The fifth hanging groove 95 and the sixth hanging groove 96 are arranged side by side in the left-right direction. The fifth hanging groove 95 and the sixth hanging groove 96 are arranged inside the first hanging groove 91 and the second hanging groove 92 in the left-right direction.

[0267] When viewed from above, the vertical wire 32 overlaps with the hanging groove 90. Specifically, the first side wire 32B overlaps with the first hanging groove 91 when viewed from above. In other words, the first hanging groove 91 extends in the front-rear direction along the first side wire 32B on the first side wire 32B. Also, the second side wire 32C overlaps with the second hanging groove 92 when viewed from above. In other words, the second hanging groove 92 extends in the front-rear direction along the second side wire 32C on the second side wire 32C.

[0268] The vehicle seat S further includes a vibration generating device 173 that generates vibrations. The vibration generating device 173 includes an eccentric motor or the like. The vibration generating device 173 is arranged on the first pressure receiving member 30. The vibration generating device 173 is arranged inside the seat cushion pad P1.

[0269] When viewed from above, the vibration generating device 173 is arranged at a position that does not overlap with the mesh portion 360 of the first pressure receiving member 30. Specifically, when viewed from above, the vibration generating device 173 is arranged at a position that overlaps with the side support portion 312 as a support portion. Specifically, two vibration generating devices 173 are provided. The two vibration generating devices 173 are arranged side by side in the left-right direction. The right vibration generating device 173 overlaps with the right side support portion 312 when viewed from above. The right vibration generating device 173 is arranged on the right side support portion 312. The left vibration generating device 173 overlaps with the left side support portion 312 when viewed from above. The left vibration generating device 173 is arranged on the left side support portion 312.

[0270] Furthermore, the vibration generator 173 is positioned so that its front-to-back position coincides with that of the transverse wire 33. More specifically, the left and right vibration generators 173 are positioned so that their front-to-back positions coincide with those of the second transverse wire 332. The two vibration generators 173 and the second transverse wire 332 are arranged side-by-side in the left-to-right direction when viewed from above. The second transverse wire 332 is positioned so that its front-to-back position coincides with that of the two vibration generators 173 when viewed from above. The second transverse wire 332 is positioned below the vibration generators 173.

[0271] Next, the effects of the vehicle seat S according to the third embodiment will be described. When viewed from above, the ventilation passage 60 overlaps with the mesh portion 360 of the first pressure-receiving member 30, allowing the mesh portion 360 to support the cushioning of the seat cushion pad P1 in the area where the ventilation passage 60 is formed. When seated, the mesh portion 360 flexes, preventing the ventilation passage 60 from being compressed more than necessary.

[0272] Because the sensor 140 does not overlap with the ventilation passage 60 when viewed from above, the load when seated can be correctly transmitted to the sensor 140 via the seat cushion pad P1, compared to, for example, the case where the sensor overlaps with the ventilation passage 60 when viewed from above. The ventilation passage 60 is less likely to affect the detection of the sensor 140.

[0273] When viewed from above, the vertical wires 32 overlap with the ventilation passages 60, thereby supporting the cushioning of the seat cushion pad P1 in the area where the ventilation passages 60 are formed.

[0274] When viewed from above, the overlapping portions L1 to L4 of the vertical wire 32 and the horizontal wire 33 overlap with the ventilation holes 65A to 65D, thereby supporting the cushioning performance in the areas where the ventilation holes 65A to 65D of the seat cushion pad P1 are formed, thus preventing a decrease in cushioning performance.

[0275] When viewed from above, the vertical wire 32 overlaps with the suspension groove 90, allowing the vertical wire 32 to efficiently support the load when suspending the seat cushion cover SK1 into the suspension groove 90. This improves the workability when suspending the seat cushion cover SK1 into the suspension groove 90.

[0276] By ensuring that the vibration generator 173 does not overlap with the mesh portion 360 when viewed from above, it is possible to suppress the absorption of vibrations generated by the vibration generator 173 by the mesh portion 360, which would otherwise make it difficult for vibrations to be transmitted to the seated person.

[0277] The vibration generator 173 is positioned on the first pressure-receiving member 30 and, when viewed from above, overlaps with the plate-shaped side support portion 312, allowing the load of the seated person to be supported by the plate-shaped side support portion 312 via the vibration generator 173. Furthermore, supporting the vibration generator 173 with the side support portion 312 makes it easier to transmit vibrations to the seated person.

[0278] Furthermore, in the third embodiment, the vehicle seat S may be configured such that, for example, the vertical wires 32 do not overlap with the ventilation passages when viewed from above. Also, in the third embodiment, the vehicle seat S may be configured such that the portion where the vertical wires 32 and horizontal wires 33 overlap does not overlap with the ventilation holes when viewed from above. Also, in the third embodiment, the vehicle seat S may be configured such that the vertical wires 32 do not overlap with the suspension grooves when viewed from above. Also, in the third embodiment, the vehicle seat S may be configured such that the vibration generator 173 overlaps with the mesh portion 360 when viewed from above. Also, in the third embodiment, the vehicle seat S may be configured without the vibration generator 173.

[0279] In the above embodiment, the entire wires 32 and 33 were covered by the resin member 31 (elastic member), but for example, only a part of the wire may be covered by the resin member (elastic member). In other words, a part of the wire may be exposed from the resin member (elastic member).

[0280] In the above embodiment, the side frame cover 40 was configured to cover the upper side and the left-right inner side of the rear end of the first side frame 11. However, for example, the side frame cover may be configured to cover only the left-right inner side of the rear end of the first side frame. Also, the vehicle seat may be configured without a side frame cover.

[0281] In the above embodiment, the blower 110 was directly attached to the resin member 31 (elastic member), but for example, the blower may be attached to the elastic member via a bracket or the like.

[0282] In the above embodiment, the sensor 140 was positioned so as not to overlap with the duct 120 when viewed from above. However, for example, the sensor may be positioned so as to overlap with the duct when viewed from above.

[0283] In the above embodiment, the second end portion 122 of the duct 120 (the connection portion between the duct and the ventilation passage) was positioned in the front-rear direction at the same location as the sensor 140. However, for example, the connection portion between the duct and the ventilation passage does not necessarily have to be positioned in the front-rear direction at the same location as the sensor.

[0284] For example, the blower, blower mounting section, duct, ECU (control unit), sensor, etc., may be arranged symmetrically to those in the embodiments and modified examples described above.

[0285] In the above embodiment, the sensor mounting portions 340A and 340B had recesses 344, but for example, the sensor mounting portions may be configured without recesses. In the above embodiment, the first pressure receiving member 30 (pressure receiving member) had two sensor mounting portions 340A and 340B to which the sensor 140 could be attached, but for example, the pressure receiving member may be configured to have only one sensor mounting portion. In the above embodiment, the first pressure receiving member 30 (pressure receiving member) had two through holes 351 and 352 through which the duct 120 could pass, but for example, the pressure receiving member may be configured to have only one through hole for the duct to pass through. The reinforcing wire does not have to be a wire positioned in the center in the left-right direction of the pressure receiving member.

[0286] In the above embodiment, the sensor 140 was a pressure sensor. However, for example, the sensor may be a temperature sensor, a humidity sensor, a sound sensor, a light sensor, a heartbeat sensor, a respiration sensor, a sensor for detecting the movement of the seated person, a sensor for detecting the sweating amount of the seated person, or the like.
