Technical Field

[0003] The invention relates to a comfortable seat for a vehicle. Background Art

[0004] As a vehicle seat, for example, Japanese Patent No. 2014-162431 discloses a vehicle seat, which includes a seat cushion frame, two front and rear wires spanned between a front panel and a rear tube of the seat cushion frame, and a central wire and a cross wire intersecting the two front and rear wires. In this technology, the wires arranged inside the seat cushion frame function as components that bear the weight of the seated person through the seat cushion. Summary of the invention

[0005] The idea that this component that bears the weight of the seated person (hereinafter referred to as "support component") can provide the seated person with a sense of comfort is desirable.

[0006] The object of the present invention is to provide a vehicle seat which can make people feel more comfortable when sitting.

[0007] In addition, an object of the present invention is to enhance the rigidity of the supporting member.

[0008] Another object of the present invention is to enhance the mounting rigidity of the sensor.

[0009] Another object of the present invention is to easily form holes for mounting other members.

[0010] In addition, an object of the present invention is to prevent the supporting member from forming a complicated structure.

[0011] In order to achieve the aforementioned objectives, the vehicle seat of the present invention comprises: a pair of relative frames spaced apart in a relative state and a pair of connecting frames spaced apart, the direction of the pair of connecting frames being orthogonal to the direction of the pair of relative frames, and the pair of connecting frames connecting the pair of relative frames; erection wires erected on the pair of connecting frames; reinforcing wires arranged to cross the erection wires when viewed from the seated person's side; and a plate-like resin member for covering at least the portion where the erection wires and the reinforcing wires cross, so that the erection wires and the reinforcing wires are spaced apart from each other and do not contact each other, and connecting the erection wires and the reinforcing wires.

[0012] According to this structure, the support member can be composed of a mounting wire, a reinforcing wire, and a plate-like resin member covering the mounting wire and the reinforcing wire. Therefore, the weight of the seated person can be borne by the surface having an effective bearing area. In addition, compared with the case where the support member is composed of a metal plate, the support member can be designed to have sufficient elasticity to be more applicable. Moreover, the plate-like resin member can be reinforced by the mounting wire and the reinforcing wire, so that the support member can have sufficient rigidity. According to this characteristic, the seated person can feel more comfortable when sitting.

[0013] The above-mentioned vehicle seat can be made into the following structure: one of the installation wire and the reinforcement wire has a second part that intersects with the first part of the other and a third part that bends and extends from the second part to one end of the first part; the resin component includes a first covering part covering the first part, a second covering part covering the third part, and a connecting part connecting the first covering part and the second covering part; the third part is not parallel to the first part.

[0014] Therefore, compared with the case where the third portion and the first portion are parallel, one of the first covering portion and the second covering portion connected by the connecting portion is less likely to rotate about the other, thereby enhancing the rigidity of the resin member and the rigidity of the supporting member.

[0015] The above-mentioned vehicle seat can also be made into the following structure: the resin component includes a wire covering portion that wraps the mounting wire or the reinforcing wire, and the wire covering portion protrudes toward the side of the seated person or the side opposite to the side of the seated person; and a beam, the beam protruding in the same direction as the wire covering portion and connected to the wire covering portion.

[0016] According to this structure, the rigidity of the resin member can be enhanced, and the rigidity of the supporting member can also be enhanced.

[0017] The above-mentioned vehicle seat can also be made into the following structure: the beam includes a first beam, one end of which is connected to the part of the wire covering portion protruding toward the seated person, and the protrusion of the first beam gradually decreases toward the other end of the first beam.

[0018] According to this structure, the step difference caused by the first beam can be reduced, so that a person can feel more comfortable when sitting on the seat.

[0019] The above-mentioned vehicle seat can also be made into the following structure: the wire covering portion includes a mounting wire covering portion covering the mounting wire and a reinforcing wire covering portion covering the reinforcing wire; the beam includes a second beam, one end of the second beam is connected to the mounting wire covering portion, and the other end is connected to the reinforcing wire covering portion.

[0020] According to this structure, the rigidity of the resin member can be further enhanced, and the rigidity of the supporting member can be further enhanced.

[0021] The vehicle seat further comprises a sitting sensor, which is used to detect the sitting state of the occupant on the vehicle seat; a plurality of the erection wires are arranged in parallel in relative directions; and the sitting sensor is arranged between adjacent erection wires. .

[0022] According to this structure, the seating sensor is provided between the high-rigidity portions of the resin member reinforced by the adjacent cross wires, and therefore, the mounting rigidity of the seating sensor can be enhanced.

[0023] The vehicle seat may also be configured as follows: the resin member includes a mounting hole for mounting other members, and the mounting hole is located away from a portion covering the installation wire or the reinforcement wire.

[0024] According to this structure, the mounting hole can be easily formed in the resin member. Moreover, for example, compared with the case where a claw-shaped portion or the like that engages with other members is formed on the resin member, this structure can prevent the supporting member from having a complicated structure.

[0025] The above-mentioned vehicle seat can also be made into the following structure: at least one of the installation wire and the reinforcement wire includes: a first parallel portion and a second parallel portion arranged parallel to a straight line; and a bending portion, the bending portion is arranged between the first parallel portion and the second parallel portion, and the bending portion deviates from the straight line; the resin component includes a bending portion covering portion covering the bending portion and a wall thickness portion, the wall thickness portion connects one end of the bending portion covering portion close to the first parallel portion and one end close to the second parallel portion.

[0026] According to this structure, the rigidity of the resin member can be enhanced, and the rigidity of the supporting member can also be enhanced.

[0027] The vehicle seat further comprises a sitting sensor for detecting a sitting state of a occupant on the vehicle seat; the sitting sensor is arranged inside the area enclosed by the curved portion covering part and the thick wall part.

[0028] According to this structure, the seating sensor is provided inside the high-rigidity portion of the resin member reinforced by the cross-wire and the thick wall portion, and the mounting rigidity of the seating sensor can be enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] An embodiment of the present invention will be described below with reference to the accompanying drawings. In the following description, the front-back, left-right, and up-down directions are based on the front-back, left-right, and up-down directions of a person sitting on the seat (sitter).

[0045] like Figure 1 As shown, the vehicle seat of this embodiment is a vehicle seat S used for a driver's seat and a passenger seat (a seat next to the driver's seat) of a car, and mainly includes a seat cushion S1 and a seat back S2.

[0046] like Figure 2 As shown, the seat cushion S1 includes a cushion frame F1 inside, which constitutes the frame of the seat cushion S1. The seat cushion S1 includes the cushion frame F1 loaded with a cushion material composed of polyurethane foam or similar materials and a material composed of fiber fabric and leather wrapped outside. Figure 2 As shown in FIG. 1 , the seat back S2 includes a back frame, which constitutes the frame of the seat back S2 . The seat back S2 includes the back frame loaded with cushion material and external wrapping material.

[0047] The cushion frame F1 includes left and right side frames 11 as a pair of opposing frames, a front frame 12 as a first connecting frame, a rear frame 13 as a second connecting frame, and a flat plate frame 14 as a limiting frame. In the present embodiment, the left-right direction corresponds to "the relative direction of the pair of opposing frames", and the front-back direction corresponds to "the orthogonal direction orthogonal to the relative direction (left-right direction) of the pair of opposing frames". In addition, in the present embodiment, the upper side corresponds to "the seated person's side", and the lower side corresponds to "the side opposite to the seated person's side".

[0048] The left and right side frames 11 are long frames in the front-rear direction and are arranged in a spaced manner in a state of facing each other in the left-right direction. Each side frame 11 is made of a metal plate, and its peripheral portion has a cross-sectional shape extending inward in the left-right direction.

[0049] The front frame 12 and the rear frame 13 are spaced apart in the front-to-rear direction, and constitute a pair of connection frames that connect the left and right side frames 11. In detail, the front frame 12 and the rear frame 13 are composed of metal pipes, and the front frame 12 connects the front parts of the left and right side frames 11. In addition, the rear frame 13 is spaced apart from the front frame 12 behind the front frame 12, and connects the rear parts of the left and right side frames 11.

[0050] The flat plate frame 14 is a connection frame that connects the left and right side frames 11 and is composed of a metal plate. The flat plate frame 14 is provided to connect the front end portions of the left and right side frames 11.

[0051] A plate-like support member 20 is provided on the inner side of the frame-like cushion frame F1, that is, between the left and right side frames 11. The support member 20 bears the weight of the seated person through the cushion material (not shown) of the seat cushion S1, and includes a mounting wire 100, a reinforcing wire 200 and a plate-like resin member 300. The mounting wire 100 and the reinforcing wire 200 are provided between the left and right side frames 11, and details are described later. The mounting wire 100 and the reinforcing wire 200 are made of metal wire. The resin member 300 is made of resin and is manufactured by an insert molding process or a similar process, and is used to cover the mounting wire 100 and the reinforcing wire 200. In this way, the mounting wire 100 and the reinforcing wire 200 are integrated with the resin member 300.

[0052] like Figure 3 As shown in (a), the erection wires 100 are erected on the front frame 12 and the rear frame 13. In this embodiment, a plurality of erection wires 100 are arranged side by side in the left-right direction. Specifically, the erection wires 100 include left and right first longitudinal wires 110 as left and right first erection wires, and two second longitudinal wires 120 as second erection wires.

[0053] Left and right first longitudinal lines 110 are spaced apart in the left-right direction, and the first longitudinal lines 110 respectively include a front extension portion 111 and a rear extension portion 112 as extension portions, a bending portion 113, a front inclined portion 114, a front hook portion 115, a rear inclined portion 116 and a rear hook portion 117.

[0054] The front extension portion 111 and the rear extension portion 112 extend substantially in the front-rear direction. In the present embodiment, the front extension portion 111 corresponds to a "first extension portion", and the rear extension portion 112 corresponds to a "second extension portion".

[0055] The front inclined portion 114 extends obliquely forward and upward from the front end of the front extending portion 111 , and the rear inclined portion 116 extends obliquely upward and rearward from the rear end of the rear extending portion 112 .

[0056] The front hook 115 is a portion locked by the front frame 12, extending from the front end of the front inclined portion 114 and forming a generally arc shape protruding upward. The rear hook 117 is a portion locked by the rear frame 13, extending from the upper end of the rear inclined portion 116 and forming a generally arc shape.

[0057] A curved portion 113 is formed between the front extension portion 111 and the rear extension portion 112 in the front-to-rear direction, and is bent into a substantially U-shaped shape and protrudes outwardly in the left-right direction relative to the front-to-rear extension portions 111 and 112. As shown in FIG. 6 , the curved portion 113 is located above the plane PL passing through the respective extension portions 111 and 112 of the left-to-right first longitudinal line 110. In other words, the curved portion 113 is formed by protruding obliquely upwardly from the front-to-rear extension portions 111 and 112 outwardly in the left-to-right direction. Figure 3 As shown in (a), the front extension portion 111 extends approximately forward from one end of the inner side of the left-right direction of the curved portion 113, that is, the front end, and the rear extension portion 112 extends approximately rearward from the other end of the inner side of the left-right direction of the curved portion 113, that is, the rear end.

[0058] The second longitudinal line 120 is arranged in parallel along the left-right direction between the left and right first longitudinal lines 110 , and each of the second longitudinal lines 120 includes an extension portion 121 , a front inclined portion 124 , a front hook portion 125 , a rear inclined portion 126 and a rear hook portion 127 .

[0059] The extension portion 121 extends substantially in the front-to-back direction and is disposed substantially parallel to the front-to-back extension portions 111 and 112 of the left and right first longitudinal lines 110 .

[0060] The front inclined portion 124 and the front hook-shaped portion 125 are formed in substantially the same shape as the front inclined portion 114 and the front hook-shaped portion 115 of the first longitudinal wire 110, and the rear inclined portion 126 and the rear hook-shaped portion 127 are formed in substantially the same shape as the rear inclined portion 116 and the rear hook-shaped portion 117 of the first longitudinal wire 110. In the present embodiment, the front hook-shaped portions 115 and 125 of the longitudinal wires 110 and 120 correspond to "hook-shaped portions formed on the stringing wires".

[0061] The reinforcing wire 200 is arranged to cross the erection wire 100 (the first longitudinal wire 110 and the second longitudinal wire 120) when viewed from the upper side. In this embodiment, a plurality of reinforcing wires 200 are arranged side by side in the front-to-back direction. Specifically, the reinforcing wire 200 includes a first transverse wire 210 and a second transverse wire 220 arranged in front of the first transverse wire 210.

[0062] The first horizontal wire 210 is composed of a single wire, including a first wire portion 211 and left and right first supporting portions 212 as a first reinforcing wire, and left and right second wire portions 213 as a second reinforcing wire. The first wire portion 211 and the second wire portion 213 are arranged to intersect with the extension portion 121 of the second longitudinal wire 120.

[0063] The first line portion 211 extends in the left-right direction. As shown in FIG. 5 , a portion of the first line portion 211 is located behind the ischium position SP so as to avoid the ischium position SP of the seated person. In detail, the first line portion 211 includes left and right end portions 211A, a middle portion 211B that is bent from the inner end portion of each end portion 211A in the left-right direction and extends obliquely to the inner side in the left-right direction, and a central portion 211C that extends in the left-right direction so as to connect the rear ends of the left and right middle portions 211B, and the central portion 211C is disposed behind the ischium position SP. On the other hand, the left and right end portions 211A are disposed at a position that is further forward than the ischium position SP. The left and right end portions 211A may also be disposed at the same position as the ischium position SP in the front-rear direction. In the present specification, the ischium position SP corresponds to the protruding portion at the bottom of the ischium area of ​​the seated person.

[0064] The first support portion 212 bends backward from the left and right ends of the first line portion 211 (the ends on the left and right outer sides of each end portion 211A) and extends approximately in the front-to-back direction. Each first support portion 212 extends approximately in the front-to-back direction along the front extension portion 111 and the rear extension portion 112 of the corresponding first longitudinal line 110, and is disposed on the lower side of the front extension portion 111 and the rear extension portion 112. In this way, the first support portion 212 passes through the resin member 300 to support the front extension portion 111 and the rear extension portion 112 of the first longitudinal line 110 from the lower side, and further supports the bent portion 113 from the lower side through the front extension portion 111 and the rear extension portion 112. Figure 3 As shown in (a), the portion where the first horizontal line 210 intersects with the first vertical line 110, that is, the first supporting portion 212, is arranged below the front and rear extending portions 111, 112 of the first vertical line 110, and on the other hand, the portion where the first horizontal line 210 intersects with the second vertical line 120 is arranged above the second vertical line 120. Specifically, the central portion 211C of the first line portion 211 of the first horizontal line 210 and the end portion on the inner side of the second line portion 213 in the left-right direction are arranged above the extending portion 121 of the second vertical line 120.

[0065] The second line portion 213 is bent from the rear end of each first support portion 212 to the inside in the left-right direction and extends to the inside in the left-right direction, and is arranged behind the first line portion 211 and parallel to the first line portion 211. Figure 5 As shown, the second line portion 213 is located behind the central portion 211C, and the central portion 211C is located behind the ischium position SP.

[0066] like Figure 3 As shown in FIG. 5( a ), the second horizontal line 220 includes a central portion 221 , a first middle portion 222 , a second middle portion 223 and an end portion 224 .

[0067] The central portion 221 extends in the left-right direction, is disposed above the front inclined portion 124 of the second left-right longitudinal lines 120 , and intersects the front inclined portion 124 .

[0068] The first intermediate portion 222 is bent and extended rearward from both left and right ends of the central portion 221 , that is, extends in a direction toward which one end (rear end) of the front inclined portion 124 points.

[0069] The second middle portion 223 is bent and extended outward in the left-right direction from the rear end of the first middle portion 222. The second middle portion 223 is disposed above the front extension portion 111 of the first longitudinal line 110 so that the left-right outer end of the second middle portion 223 intersects the front extension portion 111 from above.

[0070] The end portion 224 is bent and extended rearward from the end portion of the second intermediate portion 223 on the outside in the left-right direction, that is, extends in the direction in which one end (the rear end) of the front extension portion 111 points.

[0071] like Figure 3 As shown in (b), the first middle portion 222 of the second horizontal line 220 is not parallel to the front inclined portion 124 of the second vertical line 120 when viewed from the top. Figure 3 As shown in (c), when viewed from the left and right direction, the first middle portion 222 intersects with the front inclined portion 124. Here, the front inclined portion 124 of the second longitudinal line 120 is equivalent to the "first portion", the central portion 221 of the second transverse line 220 is equivalent to the "second portion", and the first middle portion 222 is equivalent to the "third portion".

[0072] like Figure 3 As shown in (d), when viewed from the left and right direction, the end 224 of the second horizontal line 220 intersects the front extension 111 of the first longitudinal line 110, and is not parallel to the front extension 111. Here, the front extension 111 of the first longitudinal line 110 is equivalent to the "first portion", the second middle portion 223 of the second horizontal line 220 is equivalent to the "second portion", and the end 224 is equivalent to the "third portion".

[0073] like Figure 3 As shown in (a), the resin member 300 covers the overhead wire 100 and the reinforcing wire 200, and connects the overhead wire 100 and the reinforcing wire 200. Furthermore, the overhead wire 100 and the reinforcing wire 20 do not contact at the intersection, and the resin member 300 covers and connects the overhead wire 100 and the reinforcing wire 200 in a spaced state at a predetermined distance. Therefore, the resin member 300 (in detail, the resin constituting the resin member 300) exists in each gap formed by the intersection of the overhead wire 100 and the reinforcing wire 200. The gap is formed by the portion of the overhead wire 100 that intersects with the reinforcing wire 200 and the portion of the reinforcing wire 200 that intersects with the overhead wire 100.

[0074] like Figure 4 As shown, the resin member 300 includes a base portion 310 , a wire covering portion 320 , a mounting portion 330 , a second support portion 340 , a front locking portion 350 as a locking portion, a rear locking portion 360 , and a pair of left and right frame abutting portions 370 .

[0075] The wire covering portion 320 covers and wraps the erection wire 100 or the reinforcement wire 200. In this embodiment, the wire covering portion 320 has a bead-like structure with a base portion 310 and a mounting portion 330 protruding upward. The wire covering portion 320 includes a first longitudinal wire covering portion 321 covering the first longitudinal wire 110, a second longitudinal wire covering portion 322 covering the second longitudinal wire 120, a first transverse wire covering portion 323 covering the first transverse wire 210, and a second transverse wire covering portion 324 covering the second transverse wire 220. In this embodiment, the first longitudinal wire covering portion 321 and the second longitudinal wire covering portion 322 are equivalent to the "erection wire covering portion", and the first transverse wire covering portion 323 and the second transverse wire covering portion 324 are equivalent to the "reinforcement wire covering portion". The wire covering portion 320 is formed by filling resin in each portion where the mounting wire 100 and the reinforcing wire 200 cross each other, so as to connect the mounting wire 100 and the reinforcing wire 200 .

[0076] The base portion 310 is a portion between the left and right first longitudinal line covering portions 321 and is provided to connect adjacent first longitudinal line covering portions 321 and second longitudinal line covering portions 322 or adjacent second longitudinal line covering portions 322. The base portion 310 includes a horizontal portion 311 and an inclined portion 312 formed at the front side of the support member 20.

[0077] like Figure 8 As shown in the enlarged view, the horizontal portion 311 extends in a substantially front-to-rear direction along the extension portion 121 of the second longitudinal line 120. On the upper surface of the horizontal portion 311, a plurality of ribs 313 protruding upward are formed, and the protruding direction is the same as the protruding direction of the wire coating portion 320. Each rib 313 is connected to the wire coating portion 320 and is formed integrally with the wire coating portion 320. In other words, each rib 313 is formed by extending from the wire coating portion 320. According to this configuration, the rigidity of the resin member 300 can be enhanced, and the rigidity of the support member 20 can also be enhanced.

[0078] In this embodiment, the beam 313 includes a first beam 313A, a second beam 313B, and a third beam 313C.

[0079] The first beam 313A is disposed between the front and rear first horizontal wire covering portions 323, and extends in a generally front-to-rear direction. Each first beam 313A has one end (rear end) connected to the wire covering portion 320, and is particularly connected to the first horizontal wire covering portion 323 (the portion covering the second wire portion 213) on the rear side of the wire covering portion 320. The first beam 313A has another end (front end), and the upper surface of the first beam 313A is inclined forward and downward, that is, the protrusion of the front end from the upper surface of the horizontal portion 311 is slowly reduced. According to this structure, the step difference generated by the first beam 313A can be reduced, so that people feel more comfortable when sitting on the seat.

[0080] The second beam 313B and the third beam 313C are arranged between the first horizontal line covering portion 323 and the second horizontal line covering portion 324, and extend obliquely to the left and right directions. One end (front end) of each second beam 313B is connected to the second longitudinal line covering portion 322, and the other end (rear end) is connected to the first horizontal line covering portion 323 (the portion covering the first line portion 211) on the front side. According to this structure, the rigidity of the resin component 300 can be further enhanced, and the rigidity of the supporting component 20 can also be further enhanced. The third beam 313C extends parallel to or orthogonally to the second beam 313B. In the present embodiment, the second beam 313B and the third beam 313C form a lattice structure between the first horizontal line covering portion 323 and the second horizontal line covering portion 324. According to this structure, the rigidity of the resin component 300 can be further enhanced, and the rigidity of the supporting component 20 can also be further enhanced.

[0081] The inclined portion 312 extends obliquely forward and upward from the front end of the horizontal portion 311 along the front inclined portions 114 and 124 of the longitudinal lines 110 and 120 (see also FIG. 14 ). Figure 7 As shown, a sitting sensor 30 is provided on the upper side of the inclined portion 312. The sitting sensor 30 is a well-known sensor for detecting when a seated person sits on the vehicle seat S. In the present embodiment, the sitting sensor 30 is provided between adjacent erection wires 100, specifically, between the second longitudinal wires 120. In detail, the sitting sensor 30 is provided between the second longitudinal wire covering portions 322 near the center of the upper side of the inclined portion 312. According to this structure, the sitting sensor 30 is provided between the high-rigidity portions of the resin member 300 that are reinforced by the adjacent second longitudinal wires 120, and the installation rigidity of the sitting sensor 30 can be enhanced. A first through hole 314 that is approximately rectangular and penetrates from top to bottom is formed near the center of the inclined portion 312. As shown in FIG. Fig. 9 As shown, the wire harness 31 extends from the seating sensor 30 through the first through hole 314 , is pulled out from the lower side of the support member 20 , is laid toward the front side, and is connected to the interface 32 mounted on the flat panel frame 14 .

[0082] like Figure 8As shown, the second longitudinal line covering portion 322 of the resin component 300 includes a first covering portion 322A covering the front side inclined portion 124, the second transverse line covering portion 324 includes a second covering portion 324A covering the first middle portion 222, and the base portion 310 includes a connecting portion 310A connecting the first covering portion 322A and the second covering portion 324A. As described above, the first middle portion 222 is not parallel to the front side inclined portion 124, so compared with the prior art where the first middle portion 222 is parallel to the front side inclined portion 124, the first covering portion 322A and the second covering portion 324A connected by the connecting portion 310A are in a twisted positional relationship and will not rotate relative to each other. In other words, the vicinity of the connecting portion 310A of the resin component 300 is not easily deformed. According to this structure, the rigidity of the resin component 300 can be enhanced, and the rigidity of the supporting member 20 can also be enhanced.

[0083] The mounting portion 330 is a plate-like portion constituting the front side portion of the left and right ends of the resin member 300, and is arranged to extend outward in the left and right directions from the front ends of the left and right first longitudinal wire covering portions 321. The mounting portion 330 extends forward and backward along the front inclined portions 114 and 124 of the longitudinal lines 110 and 120. A plurality of mounting holes 331 penetrating from top to bottom are formed in the mounting portion 330, which is a position of the resin member 300 avoiding the wire covering portion 320. The mounting holes 331 are used to mount other components on the support member 20. As other components mounted on the support member 20, for example, Fig. 9 As shown, the wiring harnesses 81 to 83 and the like connected to the electric components such as the motor and the panel heating device (not shown) provided on the vehicle seat S. Specifically, the wiring harnesses 81 to 83 are clamped by the wiring harness clamp 84, and the claws of the wiring harness clamp 84 are engaged in the mounting hole 331, and the wiring harnesses are mounted on the support member 20 as the wiring harness. In this way, since the mounting hole 331 is formed at a position avoiding the wire covering portion 320, the mounting hole 331 for mounting other components on the resin member 300 can be easily formed. Moreover, this structure is more advantageous for mounting other components. For example, compared with the prior art in which a claw-shaped portion for engaging other components is formed on the resin member 300, this structure can prevent the support member 20 from forming a complicated structure. The wiring harnesses 81 to 83 are connected to the interface 85 installed on the flat frame 14. As long as it is a position avoiding the wire covering portion 320, for example, a hole for mounting other components can be provided at the base portion 310 or the like.

[0084] like Figure 4As shown, the second support portion 340 is a generally plate-shaped portion constituting the rear portion of the left and right ends of the resin member 300, and is formed by extending obliquely upward from the base portion 310 (specifically, the rear ends of the horizontal portion 311 and the inclined portion 312) to the outside in the left-right direction. The second support portion 340 wraps and covers the rear end of the front extension portion 111 of the first longitudinal line 110, the rear extension portion 112 and the curved portion 113, the left and right ends of the first transverse line 210, and the end 224 of the second transverse line 220. Fig. 9 As shown, beams 341 and 342 protruding downward are formed under the second support portion 340. The plurality of beams 341 extend substantially in the front-rear direction and are arranged in parallel in the left-right direction. The plurality of beams 342 extend substantially in the left-right direction and are arranged in parallel in the front-rear direction. Figure 6 As shown, the beam 342 extending horizontally is substantially triangular in shape when viewed from the front-to-back direction, and extends from the outside of the left-right outer end of the curved portion 113 to the inside of the left-right inner end of the curved portion 113 .

[0085] like Figure 8 As shown, in this embodiment, each second support portion 340 includes a first covering portion 340A covering the rear end portion of the front extension portion 111 of the first longitudinal line 110, a second covering portion 340B covering the end portion 224 of the second transverse line 220, and a connecting portion 340C connecting the first covering portion 340A and the second covering portion 340B. As described above, the end portion 224 is not parallel to the front extension portion 111, so compared with the prior art in which the end portion 224 is parallel to the front extension portion 111, the first covering portion 340A and the second covering portion 340B are difficult to rotate relative to each other, and the vicinity of the connecting portion 340C of the second support portion 340 is not easy to deform. In this way, the rigidity of the resin member 300 can be enhanced, and the rigidity of the support member 20 can also be enhanced.

[0086] The front locking portion 350 is a portion locked to the front frame 12 and is formed into a substantially semi-cylindrical shape that is long in the left-right direction. The front locking portion 350 is a part of the resin member 300 (i.e., the resin constituting the resin member 300) and is used to wrap the front hook portions 115 and 125 of the longitudinal wires 110 and 120.

[0087] like Figure 4 As shown, the rear locking portion 360 is a portion locked to the rear frame 13. The rear locking portion 360 includes left and right first rear locking portions 361 and a second rear locking portion 362 disposed between the left and right first rear locking portions 361. The left and right first rear locking portions 361 are resin members that cover the rear hook portions 117 of the respective first longitudinal lines 110. Similarly, the second rear locking portion 362 is a resin member that covers the rear hook portions 127 of the two second longitudinal lines 120. Fig. 9As shown in (a) and (b), the path of the harnesses 81 and 82 is set to pass through the gap formed between the first rear locking portion 361 and the second rear locking portion 362 on the left side of the rear frame 13. The gap between the first rear locking portion 361 and the second rear locking portion 362 forms a recessed portion with respect to the upper portions of the first rear locking portion 361 and the second rear locking portion 362, so by arranging the harnesses 81 and 82 in this portion, the step difference caused by arranging the harnesses 81 and 82 can be reduced.

[0088] like Figure 4 As shown, the frame contact portion 370 can contact the position restriction surface 14A (see FIG. 14A ) of the flat panel frame 14 from the inner side in the left-right direction. Fig.10 ) is provided on the left and right sides of the front locking portion 350. Specifically, the frame contact portion 370 is provided to extend upward from the left and right sides of the front locking portion 350 and to exceed the front locking portion 350. On the left and right outer sides of the front end of the frame contact portion 370, there is a contact surface 371 that contacts the position limiting surface 14A of the flat panel frame 14.

[0089] like Fig.10 As shown, the flat panel frame 14 has a pair of position limiting surfaces 14A that are opposite to each other in the left-right direction. Specifically, the flat panel frame 14 includes a roughly U-shaped recessed portion 14B that protrudes toward the front side at the left-right center of the rear end portion, and the left and right surfaces of the recessed portion 14B are the position limiting surfaces 14A. The front end portion of the resin member 300 (support member 20) enters into the recessed portion 14B of the flat panel frame 14, and the frame abutting portion 370 is adjacent to the inner side of the position limiting surfaces 14A corresponding to the left and right. Furthermore, the abutting surface 371 of the frame abutting portion 370 is adjacent to the inner side of the position limiting surfaces 14A corresponding to the left and right. The abutting surface 371 and the position limiting surface 14A each form an inclined surface (rear side) extending rearward in the left-right direction. As shown Fig.11 As shown, the frame contacting parts 370 are provided on both left and right sides of the front locking part 350 , and protrude upward from the position restriction surface 14A on the rear side of the plate frame 14 .

[0090] like Fig. 9 and 11 As shown, the flat frame 14 composed of a metal plate includes a plate-like portion 14C arranged on the left and right sides of the recess 14B and arranged on the left and right sides of the frame abutment portion 370. The wiring harnesses 82 and 83 are arranged on the lower side of the left plate-like portion 14C. In the present embodiment, the wiring harnesses 82 and 83 are equivalent to "electrical wires". According to this structure, the wiring harnesses 82 and 83 are arranged on the lower side of the seat cushion frame F1 with high rigidity, and elastic components such as the wiring harnesses 82 and 83 installed on the vehicle seat S tool part can be free from external forces. The wiring harnesses 82 and 83 clamped on the wiring harness clip 86 are installed on the flat frame 14 by snapping the wiring harness clip 86 into the mounting hole 14H formed on the plate-like portion 14C.

[0091] like Fig.12 In the bottom view shown, the resin member 300 has an outer side wall 381 and a beam 382 at the front end portion.

[0092] The outer wall 381 forms an outer wall in the left-right direction of the front end portion of the resin member 300 including an outer wall in the left-right direction of the frame contact portion 370 .

[0093] The beam 382 is provided to protrude downward, extend from the outer side wall 381 extending substantially forward and backward inward in the left-right direction, and is connected to the upper portion of the front locking portion 350. Two beams 382 are provided along the front-back direction, one of which is provided at a front position in the front-back direction, which is near the rear end of the inclined abutting surface 371 of the frame abutting portion 370, and the other is provided at a rear position in the front-back direction, which is rearward of the front position in the front-back direction. When the front locking portion 350 is locked by the front frame 12, the beam 382 is provided above the front frame 12.

[0094] like Fig.13 As shown, an air supply device 40 is provided on the lower side of the support member 20. Although not shown in the figure, the cushion material of the seat cushion S1 includes a plurality of vents formed on the upper surface and an air passage communicating with the vents. The blow-out port 40B of the air supply device 40 passes through the air duct 50 (refer to Fig.14 According to this structure, the vehicle seat S is provided so that air is blown out from the upper surface of the seat cushion S1 when the air supply device 40 is operated.

[0095] For example, the air supply device 40 is a multi-blade fan, which includes a frame 41 , an impeller 42 , and a motor (not shown) for rotating the impeller 42 .

[0096] The frame 41 includes a frame body 44 for accommodating an impeller 42 and a motor, a cylindrical blow-out portion 45 extending rearward from the left end of the frame body 44, and a plate-shaped fixing portion 46 extending outward from the frame body 44. An inlet (not shown) for inhaling air is formed on the upper surface of the frame body 44, and a blow-out port 40B for blowing out air is formed at the rear end of the blow-out portion 45. The fixing portion 46 includes a first fixing portion 46A, a second fixing portion 46B, and a third fixing portion 46C. The first fixing portion 46A is formed by extending from the frame body 44 to the right oblique front, and the second fixing portion 46B is formed by extending from the frame body 44 to the left oblique front. The third fixing portion 46C is formed by extending from the frame body 44 to the substantially rearward. A through hole 46H is formed in each fixing portion 46.

[0097] The air supply device 40 is installed on the support member 20. Specifically, the front side portion of the air supply device 40 is installed on the support member 20 through the bracket 60, and the rear side portion is directly installed on the support member 20.

[0098] The bracket 60 is installed on the lower side of the support member 20, and includes a plate-shaped bracket body 61, bosses 62A, 62B and through holes 63A, 63B. The bracket body 61 is formed in a roughly U-shape, and an opening 61A that opens upward, downward and backward is formed at a position opposite to the suction port of the air supply device 40. Bosses 62A and 62B are formed in a cylindrical shape protruding downward from the lower surface of the bracket body 61. The boss 62A is arranged on the right side of the front end of the bracket body 61, and the boss 62B is arranged on the left side of the front end of the bracket body 61. The through holes 63A and 63B are holes that penetrate from top to bottom. The through holes 63A and 63B clamp the opening 61A, and the through hole 63A is arranged on the right side of the rear end of the bracket body 61, and the through hole 63B is arranged on the left side of the rear end of the bracket body 61.

[0099] like Fig. 9 As shown, the resin member 300 constituting the support member 20 includes left and right fan mounting parts 390R, 390L for mounting an air supply device 40. In the present embodiment, the mounting position of the air supply device 40 is set according to different specifications of the vehicle seat S. Specifically, according to the specifications of the vehicle seat S, the air supply device 40 can be mounted on either the right air supply device mounting part 390R or the left air supply device mounting part 390L. For example, when the vehicle seat S is used for the right seat, the air supply device 40 is mounted on the right air supply device mounting part 390R, and when the vehicle seat S is used for the left seat, the air supply device 40 is mounted on the left air supply device mounting part 390L. The structures of the left and right air supply device mounting parts 390R, 390L are roughly the same, so the following mainly describes in detail the structure of the right air supply device mounting part 390R.

[0100] like Fig.13As shown, the air supply device mounting portion 390R includes a plurality of cylindrical bosses 391 protruding downward from the bottom of the resin member 300. The boss 391 includes a first boss 391A, a second boss 391B and a third boss 391C. The first boss 391A, the second boss 391B and the third boss 391C are arranged to be located at the vertices of a triangle when viewed from the bottom. Specifically, the first boss 391A and the second boss 391B are arranged side by side in a state separated in the left-right direction, and the third boss 391C is arranged between the first boss 391A and the second boss 391B in the left-right direction at a position further back than the first boss 391A and the second boss 391B. The first boss 391A is arranged at the front end of the right mounting portion 330, and the second boss 391B and the third boss 391C are arranged at a position between the right first longitudinal line 110 and the right second longitudinal line 120 in the front end of the inclined portion 312. Furthermore, the first boss 391A is disposed on the right side of the right first longitudinal line 110, and the second boss 391B and the third boss 391C are disposed on the left side of the right first longitudinal line 110. That is, the bosses 391 are disposed on both sides of the right first longitudinal line 110 in the left-right direction.

[0101] like Fig. 9 As shown, the first boss 391A of the left air supply device mounting portion 390L is disposed at a position between the left and right second longitudinal lines 120 in the front end portion of the inclined portion 312, and the second boss 391B and the third boss 391C are disposed at a position between the left second longitudinal line 120 and the left first longitudinal line 110 in the front end portion of the inclined portion 312. Furthermore, the first boss 391A of the left air supply device mounting portion 390L is disposed on the right side of the left second longitudinal line 120, and the second boss 391B and the third boss 391C are disposed on the left side of the left second longitudinal line 120. That is, the bosses 391A to 391C of the left air supply device mounting portion 390L are disposed on both sides of the left second longitudinal line 120 in the left-right direction.

[0102] The following description will take the air supply device 40 installed on the supporting member 20 as an example.

[0103] like Fig.13As shown, when the air supply device 40 is installed on the support member 20, the bracket 60 is first installed on the lower side of the support member 20. Specifically, the screw 91 is inserted into the through hole 63A of the bracket 60 and screwed with the first boss 391A, and the screw 92 is inserted into the through hole 63B of the bracket 60 and screwed with the second boss 391B. Then, the air supply device 40 is installed on the lower side of the bracket 60 and the support member 20. Specifically, the screw 93 is inserted into the through hole 46H of the first fixing portion 46A formed on the air supply device 40 and screwed with the boss 62A of the bracket 60, and the screw 94 is inserted into the through hole 46H of the second fixing portion 46B and screwed with the boss 62B of the bracket 60, thereby installing the front side portion of the air supply device 40 on the bracket 60. Similarly, the screw 95 is inserted into the through hole 46H of the third fixing portion 46C formed on the air supply device 40 and screwed into the third boss 391C of the resin member 300 , thereby directly mounting the rear portion of the air supply device 40 on the supporting member 20 .

[0104] In this embodiment, since a part of the air supply device 40 is mounted on the support member 20 via the bracket 60, the installation flexibility of the air supply device 40 can be improved compared to the case where the entire air supply device 40 is directly mounted on the support member 20. In addition, since the flexibility of setting the air supply device 40 in the vehicle seat S can be improved, the space in the vehicle seat S can be effectively utilized.

[0105] In particular, in the present embodiment, a part of the air supply device 40, that is, the front part, is mounted on the bracket 60, thereby mounting the air supply device 40 on the support member 20 through the bracket 60, and the rear part is directly mounted on the support member 20, so that the air supply device 40 can be mounted at a position below the front locking portion 350 where it is difficult to set the mounting boss. Accordingly, the installation flexibility of the air supply device 40 can be further improved. In addition, the installation flexibility of the air supply device 40 in the vehicle seat S can be further improved, and the space in the vehicle seat S can be more effectively utilized.

[0106] Because the air supply device 40 is installed on the resin component 300, compared with the case where the air supply device 40 is installed on the metal mounting wire 100 or other metal parts, the vibration of the supporting component 20 generated by the operation of the air supply device 40 can be reduced, and / or the noise caused by the vibration when the air supply device 40 is working can be reduced.

[0107] Furthermore, since the air supply device 40 is mounted on the protruding boss 391 provided on the resin member 300 , the installation flexibility of the air supply device 40 can be further improved compared to, for example, a case where the air supply device 40 is mounted on a flat surface of the resin member 300 .

[0108] Since the bosses 391 are provided on both sides of the cross wire 100, the air supply device 40 is provided on the resin member 300 through the high rigidity portion of the resin member 300 reinforced by the cross wire 100. According to this structure, the installation rigidity of the air supply device 40 can be enhanced.

[0109] like Fig.14 As shown, the air supply device 40 mounted on the support member 20 is arranged below the inclined portion 312 of the resin member 300 constituting the support member 20. According to this structure, the air supply device 40 can be closely arranged below the support member 20, so that the vehicle seat S including the air supply device 40 can be compactly arranged. Here, the front side portion of the air supply device 40 is arranged on the lower side of the metal front frame 12.

[0110] like Fig. 9 As shown, the inclined portion 312 of the resin member 300 is formed with a second through hole 315 that penetrates vertically at a position behind the second boss 391B. One second through hole 315 is provided on the left and right of the inclined portion 312 corresponding to the left and right air supply device mounting portions 390R and 390L. Fig.14 As shown, the air duct 50 connected to the blower 45 of the air supply device 40 passes through the second through hole 315. According to this structure, compared with the case where the air duct is provided bypassing the support member 20, the cushion frame F1 (seat cushion S1) can be made compact, so the vehicle seat S can be made compact.

[0111] like Figure 5 As shown, when viewed from the upper side, the portion (inclined portion 312) between the front locking portion 350 and the second through hole 315 of the resin member 300 forms a soundproof wall 316, which covers the frame body 44 of the air supply device 40, and more specifically, the impeller 42 included in the frame body 44. According to this structure, the soundproof wall 316 of the resin member 300 can block the noise generated by the rotation of the impeller 42, and the working noise transmitted to the seated person by the air supply device 40 can be reduced. In addition, when viewed from the upper side, the soundproof wall 316 can also be set to cover the entire air supply device 40 (including the blowing portion 45).

[0112] According to the above embodiment, Figure 2As shown, the support member 20 that bears the weight of the seated person is composed of a set wire 100, a reinforcing wire 200, and a plate-like resin member 300 covering the set wire 100 and the reinforcing wire 200. Therefore, the weight of the seated person can be borne by a surface having an effective bearing area. In addition, compared with the case where the support member is composed of a metal plate, the support member 20 can be designed to have sufficient elasticity to be more applicable. Moreover, the plate-like resin member 300 is reinforced with the set wire 100 and the reinforcing wire 200 made of metal, so that the support member 20 can have sufficient rigidity. According to this characteristic, the sitting feeling of the vehicle seat S can be made more comfortable. Since the resin member 300 is configured to cover and keep the set wire 100 and the reinforcing wire 200 spaced apart without contact, noise generated by contact between the wires can be prevented.

[0113] According to this embodiment, Figure 3 and 4 As shown, the left and right first longitudinal lines 110 have a substantially U-shaped bent portion 113 that protrudes and bends obliquely upward toward the left and right outer sides along the front and rear extensions 111 and 112, respectively, so that the left and right bent portions 113 can pass through the second support portion 340 of the resin member 300 to sandwich and support the seated person from both sides. In this way, the load-bearing capacity of the vehicle seat S can be enhanced. On the other hand, the bent portion 113 is formed by the bent portion of the left and right first longitudinal lines 110, so the number of parts of the vehicle seat S can be reduced compared to the case where the seated person is sandwiched and supported from both sides by a separate component.

[0114] In this embodiment, since the first support portion 212 of the first horizontal wire 210 supports the curved portion 113 from the lower side through the extension portions 111 and 112, even if the first vertical wire 110 having the curved portion 113 bends downward when the seated person sits, the curved portion 113 can be supported by the first support portion 212. Therefore, it is possible to suppress the curved portion 113 from moving too downward, that is, the curved portion 113 from dropping too much. In this way, the left and right curved portions 113 can maintain a good load-bearing capacity when the person sits.

[0115] In this embodiment, since the first support portion 212 can support the front and rear sides of the curved portion 113, specifically, can support both the front extension portion 111 and the rear extension portion 112, it can effectively prevent the curved portion 113 from excessively bending downward when the first longitudinal line 110 is deformed. In this way, the left and right curved portions 113 can maintain a better load-bearing capacity when sitting.

[0116] In this embodiment, since the portion of the first horizontal line 210 intersecting the second vertical line 120 is arranged at a position higher than the second vertical line 120, the first horizontal line 210 having the first support portion 212 can be supported by the second vertical line 120. In this way, when the first vertical line 110 is deformed downward, the first horizontal line 210 can be restrained from descending, so the first support portion 212 can more effectively restrain the curved portion 113 from descending too much. As a result, the left and right curved portions 113 can maintain a better load-bearing capacity when the user is sitting.

[0117] In this embodiment, the resin member 300 has the plate-shaped second support portion 340 covering the curved portion 113, so the second support portion 340 can support the seated person with a surface having an effective area. In this way, the sitting feeling can be improved.

[0118] In this embodiment, if Figure 6 As shown, the beam 342 provided at the lower side of the second support portion 340 extends from the upper side of the curved portion 113 inwardly in the left-right direction, so the curved portion 113 can be supported by the beam 342 to prevent it from rotating downwardly around the inner end point in the left-right direction. In this way, the left and right curved portions 113 can be prevented from deforming due to the weight of the seated person opening to the left and right outer sides, so that the left and right curved portions 113 can maintain a good load-bearing capacity when the person is seated.

[0119] In this embodiment, if Figure 5 As shown in the figure, the first line portion 211 is arranged to intersect with the longitudinal lines 110 and 120, so that the support member 20 that bears the weight of the seated person can be strengthened. In addition, the first line portion 211 is provided with a central portion 211C behind the ischium position SP so as to avoid the ischium position SP, so that the discomfort of the seated person caused by the contact of the first line portion 211 with the seated person in the ischium area and its vicinity is suppressed.

[0120] In this embodiment, the second wire portion 213 is included in addition to the first wire portion 211, so that the support member 20 can be further strengthened. In addition, the second wire portion 213 is provided at a position further back than the central portion 211C of the first wire portion 211, so that the discomfort of the sitting feeling caused by the seated person contacting the second wire portion 213 in the ischium area and the vicinity of the seated person is suppressed.

[0121] In this embodiment, if Fig.14 As shown, the portion of the air supply device 40 mounted on the support member 20 (the front portion of the air supply device 40) is disposed on the lower side of the front frame 12, so that the weight of the seated person sitting on the vehicle seat S can be received and supported by the metal front frame 12 having high rigidity. In this way, the weight of the seated person can be less likely to be applied to the air supply device 40.

[0122] In this embodiment, if Fig.10 As shown, the flat frame 14 has a pair of left and right position limiting surfaces 14A, and the support member 20 has a pair of left and right frame abutment portions 370, so when the support member 20 is as shown Fig.10 When the support member 20 moves greatly in the left-right direction, the frame contact portion 370 of the support member 20 contacts the position restriction surface 14A of the flat frame 14 from the left-right inner side. In this way, the support member 20 can be restricted from further moving in the left-right direction, that is, the position of the support member 20 can be suppressed from being deviated left-right.

[0123] In this embodiment, the support member 20 has a tendency to move in the left-right direction along the front frame 12 locked by the front locking portion 350, so by providing the frame abutting portions 370 on both the left and right sides of the front locking portion 350, the frame abutting portions 370 can be tightly abutted against the position restriction surface 14A from the inside in the left-right direction. In this way, the position of the support member 20 can be effectively suppressed from being deviated left-right.

[0124] In this embodiment, the frame contact portion 370 is more protruding upward than the position limiting surface 14A, so even if the frame contact portion 370 has a dimensional error, or the flat frame 14 moves up and down through the tilt mechanism, the frame contact portion 370 can be tightly contacted with the position limiting surface 14A. In this way, the position of the support member 20 can be more effectively suppressed from being deviated to the left and right.

[0125] In this embodiment, the support member 20 includes the beam 382 extending inward in the left-right direction from the outer side wall 381 of the frame contact portion 370, so that the rigidity of the outer side wall 381 can be improved. In this way, the rigidity of the frame contact portion 370 can be enhanced, and the position of the support member 20 can be well suppressed from being deviated left-right due to the contact between the frame contact portion 370 and the position restriction surface 14A.

[0126] In this embodiment, the frame contact portion 370 protrudes upwards more than the front locking portion 350, so the area of ​​the contact surface 371 can be sufficiently ensured. In this way, the frame contact portion 370 and the position restriction surface 14A can be well contacted, and the position of the support member 20 can be better suppressed from being deviated left and right.

[0127] In this embodiment, the position restriction surface 14A and the contact surface 371 are inclined surfaces extending obliquely to the rear side and to the outside in the left-right direction, so compared with the case where the position restriction surface 14A and the contact surface 371 are provided as surfaces perpendicular to the left-right direction, the impact when the position restriction surface 14A and the contact surface 371 contact can be reduced. In this way, the impact can be reduced when the position deviation of the support member 20 is suppressed.

[0128] Since the frame contact portion 370 is formed on the resin member 300 made of resin material, it is possible to suppress the generation of noise when the position restriction surface 14A formed on the metal plate frame 14 contacts the frame contact portion 370. Thus, it is possible to suppress the generation of noise when suppressing the positional deviation of the support member 20.

[0129] An embodiment of the invention has been described above, but the invention is not limited to the aforementioned embodiment. As described below, the specific structure can be appropriately changed within the scope of the invention. In addition, the same symbols are marked on the same structure as the aforementioned embodiment and the description is appropriately omitted below, and the differences from the aforementioned embodiment are described in detail.

[0130] For example Fig.15 As shown in (a) and (b), the support structure 20 in the modified example includes left and right first longitudinal wires 110 and a third longitudinal wire 130 as installation wires, a first transverse wire 210 as a reinforcement wire, and a resin structure 300 for covering the wires 110, 130, 210 and integrating them into one.

[0131] The third longitudinal line 130 is arranged between the left and right first longitudinal lines 110 and is mounted on the front frame 12 and the rear frame 13. The third longitudinal line 130 mainly includes a first parallel portion 131 on the front side, a second parallel portion 132 on the rear side, and a curved portion 133 arranged between the first parallel portion 131 and the second parallel portion 132. The first parallel portion 131 and the second parallel portion 132 are arranged parallel to a straight line L extending substantially in the front-back direction. Specifically, the first parallel portion 131 and the second parallel portion 132 are arranged on the same straight line L as viewed from the upper side and extend substantially in the front-back direction. The curved portion 133 deviates from the straight line L and bends in the left-right direction. Specifically, the front portion 133A of the curved portion 133 is curved to protrude from the straight line L to the right in a substantially U-shape, and the rear portion 133B is curved to protrude from the straight line L to the left in a substantially U-shape. The curved portion 133 is generally S-shaped by connecting the rear end of the front portion 133A and the front end of the rear portion 133B and extending straightly in the left-right direction.

[0132] The resin member 300 includes a third longitudinal wire covering portion 325 covering the third longitudinal wire 130 as a part of the wire covering portion 320. The third longitudinal wire covering portion 325 forms a bead-like structure protruding upward from the base portion 310 and the mounting portion 330, and includes a curved portion covering portion 326 covering the curved portion 133. The resin member 300 also includes a wall thickness portion 317 having a thickness thicker than that of the surrounding portion. The wall thickness portion 317 forms a bead-like structure protruding upward from the surrounding portion, similarly to the third longitudinal wire covering portion 325. The wall thickness portion 317 includes a first wall thickness portion 317A and a second wall thickness portion 317B. The first wall thickness portion 317A is formed in a substantially L-shape, and the L-shape connects one end of the front opening portion 326A formed by the curved portion covering portion 326, which is close to the first parallel portion 131, and one end of the front opening portion 326A, which is close to the second parallel portion 132. The second thick portion 317B is formed in a substantially L-shape, and the L-shape connects one end of the rear opening 326B formed by the curved portion covering portion 326, which is close to the first parallel portion 131, and one end of the rear opening 326B, which is close to the second parallel portion 132. According to this structure, a closed thick portion having a substantially rectangular outline is formed by the front portion of the curved portion covering portion 326 and the first thick portion 317A, and the rear portion of the curved portion covering portion 326 and the second thick portion 317B, so that the rigidity of the resin member 300 can be enhanced compared to a case where the thick portion 317 is not provided. In this way, the rigidity of the supporting member 20 can be enhanced.

[0133] In this embodiment, if Fig.15 As shown, the seat sensor 30 is arranged on the inner side of the area surrounded by the front side portion of the curved portion covering portion 326 and the first wall thickness portion 317A. According to this structure, the seat sensor 30 is arranged on the inner side of the high rigidity portion of the resin component 300 that is reinforced by the third longitudinal line 130 and the wall thickness portion 317, so that the installation rigidity of the seat sensor 30 can be enhanced. Although the bead-shaped wall thickness portion 317 is shown as the wall thickness portion in the above description, it is not limited to this. That is, the wall thickness portion only needs to be thicker than the surrounding portion, and the shape is not particularly limited. Although, Fig.15 1 shows that the third longitudinal wire 130 as the erection wire is composed of a first parallel portion 131, a second parallel portion 132, and a curved portion 133, but the present invention is not limited thereto. For example, the reinforcing wire may include a first parallel portion, a second parallel portion, and a curved portion, and both the erection wire and the reinforcing wire may include a first parallel portion, a second parallel portion, and a curved portion.

[0134] In the above-mentioned embodiment, one curved portion 113 is formed on each of the left and right first longitudinal lines 110 , but the present invention is not limited thereto, and a plurality of curved portions 113 may be formed on each of the left and right first longitudinal lines 110 .

[0135] In the above embodiment, a part of the first wire portion 211 as the first reinforcing wire is disposed behind the ischium position SP, but the present invention is not limited thereto and the first wire portion 211 may be disposed in front of the ischium position SP. In addition, the first wire portion 211 may be disposed in front of or behind the ischium position SP.

[0136] In the aforementioned embodiment, the first horizontal wire 210 is composed of one wire, including the first wire portion 211 and the first support portion 212 as the first reinforcing wire, and the two second wire portions 213 as the second reinforcing wire, but is not limited to this. For example, the first wire portion 211 and the first support portion 212 as the first reinforcing wire may be composed of one wire, and the two second wire portions 213 as the second reinforcing wire may be composed of two wires, and they may be arranged separately. If the wires constituting the first reinforcing wire and the second reinforcing wire are arranged separately, the second reinforcing wire may also be composed of one wire instead of two wires. In addition, by configuring the first reinforcing wire and the second reinforcing wire to be composed of one wire, the number of wires can be reduced compared to the case where the first reinforcing wire and the second reinforcing wire are composed of different wires, and therefore the number of parts of the vehicle seat S can be reduced.

[0137] In the aforementioned embodiment, each first support portion 212 extends in the front-rear direction along the front and rear extension portions 111, 112, and is disposed at the lower side of the front and rear extension portions 111, 112, supporting the extension portions 111, 112 from the lower side, but the present invention is not limited thereto. For example, the following structure may be adopted: the first support portion extends in the left-right direction, is disposed to intersect the lower side of one of the front extension portion 111 and the rear extension portion 112, and supports the latter from the lower side. In addition, the first reinforcing wire may also not include the first support portion.

[0138] In the aforementioned embodiment, the second horizontal wire 220 as a reinforcing wire includes a central portion 221 (second portion) and a first middle portion 222 (third portion), wherein the first middle portion 222 is not parallel to the front inclined portion 124 (first portion) of the second longitudinal wire 120 (erection wire), but is not limited to this. For example, it may also be a structure in which, instead of a reinforcing wire, the erection wire has a second portion and a third portion, wherein the third portion of the erection wire is not parallel to the first portion of the reinforcing wire. At this time, in order to enhance the rigidity of the supporting member, it is preferred that the resin member is made into the following structure, the structure including a first covering portion covering the first portion of the reinforcing wire, a second covering portion covering the third portion of the erection wire, and a connecting portion connecting the first covering portion and the second covering portion.

[0139] In the above-mentioned embodiment, the entirety of the erection wire 100 and the reinforcing wire 200 is covered by the resin member 300, but the present invention is not limited thereto, and a portion of the erection wire 100 and the reinforcing wire 200 may be exposed to the outside. For example, the following structure may be adopted: the crossing portions of the erection wire 100 and the reinforcing wire 200 are spaced from each other and are not in contact with each other and are covered and connected by the resin member, and other portions such as the bent portion 113 are not covered by the resin member.

[0140] In the above embodiment, the wire covering portion 320 protrudes toward the seated person side (upper side), but is not limited thereto, and may protrude toward the side opposite to the seated person side (lower side). Optionally, the wire covering portion 320 may protrude toward both the upper side and the lower side.

[0141] In the above-mentioned embodiment, the frame contact portion 370 of the support member 20 and the position restriction surface 14A of the flat frame 14 are directly contacted with each other, but the present invention is not limited to this. Fig.11 As shown, it is also possible to provide rubber or felt etc. on at least one of the abutting surface 371 of the frame abutting portion 370 and the position limiting surface 14A, so that the frame abutting portion 370 and the position limiting surface 14A abut against each other through the rubber or felt etc. Thus, the noise and impact when the abutting surface 371 and the position limiting surface 14A abut against each other can be reduced.

[0142] In the aforementioned embodiment, the frame abutment portion 370 is designed to protrude more upward than the front locking portion 350, but it is not limited to this. For example, the frame abutment portion protruding upward may not be provided on the resin member, and the surface on the outside of the left and right direction of the front locking portion may be used as the frame abutment portion. In the aforementioned embodiment, the position limiting surface 14A and the frame abutment portion 370 are provided on the front side of the cushion frame F1 and the support member 20, but it is not limited to this. For example, they may be provided on the rear side. In addition, the position limiting surface and the abutment surface may also be surfaces that are substantially orthogonal to the left and right directions. In addition, the frame having the position limiting surface and the frame of the locking support member may also be the same member.

[0143] In the aforementioned embodiment, the front part of the air supply device 40 is mounted on the support member 20 through the bracket 60, and the rear part is directly mounted on the support member 20, but it is not limited thereto. For example, the air supply device can be mounted on the bracket as a whole, or it can be mounted on the support member through the bracket. Alternatively, the air supply device can also be directly mounted on the support member 20 as a whole.

[0144] In the aforementioned embodiment, the air supply device 40 is disposed below the inclined portion 312, but is not limited thereto. Fig.14As shown, the air supply device may also be disposed below the horizontal portion 311. In the aforementioned embodiment, the front portion of the air supply device 40 is disposed below the front frame 12, but is not limited thereto. For example, a portion of the air supply device 40, that is, the rear portion, may also be disposed below the rear frame 13 serving as the first connecting frame.

[0145] In the above embodiment, the air supply device 40 is exemplified in the form of a multi-blade fan, but it is not limited to this, and it may be, for example, a propeller fan or a turbo blower. In the above embodiment, the vehicle seat S is configured to blow out air through the operation of the air supply device 40, but it is not limited to this, and it may be configured to inhale air through the operation of the air supply device. In addition, for example, the air supply device may switch between air supply and inhalation by switching the rotation direction of the impeller.

[0146] In the above-mentioned embodiment, the frame member is exemplified in the form of a cushion frame F1, but it is not limited to this. For example, the frame member may be a back frame constituting the frame of the seat back S2. That is, the vehicle seat S may also be configured as follows: a plate-shaped support member including a mounting wire, a reinforcing wire and a resin member is disposed on the inner side of a frame-shaped back frame, and the same structure as the seat cushion S1 of the above-mentioned embodiment is applied to the seat back S2. In addition, if the support member is disposed on the inner side of the back frame, the front side corresponds to the "side of the seated person" and the rear side corresponds to the "side opposite to the side of the seated person". In addition, in the structure in which the support member is disposed on the inner side of the back frame, when the side frames of the back frame are used as a pair of relative frames, the up-down direction corresponds to the "orthogonal direction orthogonal to the relative direction (left-right direction) of the pair of relative frames".

[0147] In some embodiments, the structure of the vehicle seat S is to set a pair of opposing support frames between the upper and lower frames of the backrest frame. In addition, in other embodiments, the structure of the vehicle seat S is to set a pair of opposing support frames between the front and rear frames of the cushion frame. In these embodiments, the left and right frames of the backrest frame and the cushion frame can be used as connecting frames. In some embodiments, the vehicle seat S can sometimes be installed with wires installed on the rear frame 13 and the flat frame 14.

[0148] In the aforementioned embodiment, the support member 20 includes the erection wire 100, the reinforcing wire 200 and the resin member 300, but is not limited thereto. For example, the support member may not include the reinforcing wire. Alternatively, a support member consisting only of the erection wire, a plate-shaped support member consisting only of resin, or a support member consisting of a metal plate may be used as the support member.

[0149] In the above-mentioned embodiment, the vehicle seat S is exemplified as being mounted on an automobile, but the invention is not limited thereto and may be a seat mounted on transportation vehicles other than automobiles, such as rail vehicles, ships, airplanes, and the like.

[0150] Furthermore, the various elements described in the above-mentioned embodiments and modifications may be implemented in any combination as needed.

[0151] It should be noted that the above embodiments illustrate the present invention rather than limit the present invention, and those skilled in the art may design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference symbol between brackets shall not be construed as a limitation to the claims.
