[0051] The following describes embodiments of the vehicle seat according to the present invention applied to a vehicle seat installed in a vehicle such as an automobile, with reference to the drawings. For the sake of explanation, the directions of up and down, front and back, and left and right will be defined based on the direction of a person seated in the vehicle seat. However, the present invention is not limited to these directions.

[0052] As shown in Figure 1, the vehicle equipped with the passenger seat 1 has two rows of seats, front and rear. The passenger seat 1 is the front seat, located to the side of the driver's seat.

[0053] However, the vehicles to which the vehicle seat 1 is applied are not limited to vehicles equipped with two rows of seats, front and rear. For example, the vehicle seat 1 may be applied to a vehicle equipped with three rows of seats, front and rear, and may constitute the front seat located in the front row.

[0054] The vehicle seat 1 comprises a seat body 2 and a speaker device 3. The seat body 2 includes a seat cushion 5 placed on the floor 4, a seat back 6 connected to the rear of the seat cushion 5, and a headrest 7 provided on the upper part of the seat back 6.

[0055] The speaker device 3 is built into the upper part of the seat body 2. By positioning the speaker device 3 on the upper part of the seat back 6, it can be placed close to the occupant's ears. This makes it possible to provide each occupant of the vehicle seat 1 with an immersive sound experience, as well as music and audio content tailored to their preferences.

[0056] In addition, a display 8 for rear-seat occupants is provided on the back of the vehicle seat 1.

[0057] Next, we will describe the details of the upper structure of the seat body 2 and the details of the configuration of the speaker device 3.

[0058] As shown in Figure 1, the upper part of the seat body 2 is composed of a seat back 6 and a headrest 7. The seat back 6 has a seat back frame 10 (see Figure 2) that forms the skeleton, a pad member 11 supported by the seat back frame 10, and a surface material 12 that covers the outer surface of the pad member 11. Note that in Figure 1, a portion of the upper right of the surface material 12 of the seat back 6 is shown peeled off to show the internal structure of the seat back 6.

[0059] The seat back frame 10 includes a pair of left and right side members 15 that extend vertically, an upper frame 16 that extends horizontally and connects the upper parts of the left and right side members 15, and a lower frame (not shown) that extends horizontally and connects the lower parts of the left and right side members 15.

[0060] The lower ends of the left and right side members 15 are preferably connected to a frame (not shown) that forms the skeleton of the seat cushion 5 via a reclining mechanism (not shown). An airbag module 18 is provided at the lower part of at least one of the left and right side members 15. The airbag module 18 houses an airbag (not shown) that deploys forward. In this embodiment, as shown in Figures 1 and 2, the airbag module 18 is connected to the left side of the left side member 15.

[0061] The headrest 7 has a headrest body 20 (see Figure 1). The headrest body 20 is connected to the seat back frame 10 via a headrest stay (hereinafter referred to as stay 21; see Figure 2).

[0062] The headrest body 20 is roughly rectangular in shape and is positioned behind the head of the seated person. The headrest body 20 may include a cushioning pad member (not shown) and a surface material (not shown) that covers the front surface of the pad member.

[0063] As shown in Figure 2, the stay 21 is made of a bent and deformed metal round pipe. The stay 21 comprises a pair of left and right vertical sections 21A and a horizontal section 21B connecting the upper ends of the left and right vertical sections 21A. Each of the vertical sections 21A extends substantially in the vertical direction. The vertical sections 21A are connected to the upper frame 16 at their lower parts. As a result, the stay 21 is coupled to the upper part of the seat back frame 10 and supported by the seat back frame 10. The stay 21 may be directly fixed to the seat back frame 10 by welding or the like, or it may be coupled to the seat back frame 10 via a cylindrical pillar guide (not shown).

[0064] The headrest body 20 is connected to the upper part of the stay 21 and is supported by the upper frame 16 via the stay 21. The stay 21 and the seat back frame 10 work together to form the upper half of the seat frame 22, which forms the skeleton above the seat body 2. The lower part of the stay 21, i.e., the lower half of the vertical part 21A, constitutes the headrest pillar that connects the headrest body 20 to the seat back frame 10.

[0065] As shown in Figure 3, the speaker device 3 includes a speaker box 25 and a speaker grille 26.

[0066] As shown in Figure 4, the speaker box 25 has two speaker bodies 28 (also called speaker drivers) and a housing 29. Each speaker body 28 includes a compression driver 28A as a sound source that generates sound and a roughly frustoconical horn 28B. The housing 29 includes a front member 29A that forms the front half and a rear member 29B that forms the rear half.

[0067] The front surface of the front member 29A is provided with two mounting holes (not shown) for housing the speaker body 28. The speaker body 28 is arranged so that each horn 28B opens forward and is housed in the mounting holes. The protruding ends of the horns 28B are connected to flanges 28C that extend radially outward, and the speaker body 28 is connected to the speaker box 25 by fastening the flanges 28C to the front member 29A. However, the speaker body 28 and the speaker box 25 may be connected by methods other than fastening (such as adhesive).

[0068] The stay 21 is provided with a support member 31 for supporting the speaker box 25. The support member 31 is made of a metal material and constitutes part of the seat frame 22 that forms the skeleton of the upper half of the seat body 2.

[0069] The support member 31 includes a pair of left and right first brackets 32 (see also Figure 2), a first wire member 33 (see also Figure 2), a second wire member 35, and a second bracket 36.

[0070] As shown in Figure 2, each first bracket 32 ​​is connected to the vertical portion 21A of the stay 21. The first bracket 32 ​​includes a lateral extension portion 32A that is connected to the vertical portion 21A and extends outward to the left and right, and a forward extension portion 32B that extends forward from the upper edge of the lateral extension portion 32A.

[0071] The first wire member 33 is made of a bent and deformed metal rod-shaped member or pipe material. The first wire member 33 may be made of, for example, a round bar or a round pipe.

[0072] The first wire member 33 comprises a pair of upper frames 33A arranged spaced apart to the left and right and each extending in the left-right direction, a pair of left and right side frames 33B extending forward and downward from the left and right edges of the upper frames 33A, and a lower frame 33C extending left and right and connecting the lower ends of the side frames 33B. Each side frame 33B is provided with a bent portion 33D that bends outward to the left and right. As a result, the first wire member 33 has a hexagonal frame shape when viewed from the front. The first wire member 33 is fixed to the stay 21 by the upper frame 33A being connected to the forward extension portion 32B.

[0073] As shown in Figure 4, the second wire member 35 is also made of a bent and deformed metal rod-shaped member or pipe material. The second wire member 35 may be made of, for example, a round bar or round pipe.

[0074] The second wire member 35 comprises a pair of left and right vertical frames 35A that are connected to the lower frame 33C and extend upward and rearward, and horizontal frames 35B that extend to the left and right and connect the upper ends of the vertical frames 35A.

[0075] The second bracket 36 is made of a bent and deformed metal plate. The second bracket 36 comprises a first plate portion 36A which is connected to the horizontal frame 35B on its main surface, and a second plate portion 36B which extends upward from the upper edge of the first plate portion 36A and has a main surface facing substantially forward.

[0076] The speaker box 25 is positioned at its lower front end so as to be in contact with the rear surface of the second plate portion 36B from the rear, and is coupled (fastened in this embodiment) to the rear surface of the second plate portion 36B. As a result, the speaker box 25, including the speaker body 28, is coupled to the stay 21 via the support member 31 and supported by the seat back frame 10.

[0077] The speaker grille 26 covers the front of the speaker box 25 and protects the speaker body 28.

[0078] As shown in Figures 3 and 5, the speaker grille 26 comprises a front grille 41 and a rear grille 42.

[0079] As shown in Figure 3, the front grille 41 is a flat plate shape that extends in the left-right direction when viewed from the front. The front grille 41 may comprise a roughly rectangular plate-shaped grille frame portion 41A and a cover portion 41B stretched across the inside of the grille frame portion 41A. The grille frame portion 41A may be made of metal or resin such as plastic, and the cover portion 41B may be made of a cloth or the like that allows sound emitted from the speaker box 25 to pass through. It is preferable that the cloth constituting the cover portion 41B is made up of a mesh. The front grille 41 may also be made of a resin plate from which the grille frame portion 41A and the cover portion 41B are integrally molded.

[0080] The rear grille 42 is also made of resin such as plastic. As shown in Figures 6(A) and 6(B), the rear grille 42 has a surface facing in the front-rear direction and has a substantially flat grille body 42A to which the front grille 41 is connected to the front.

[0081] The grille body 42A is formed in a roughly flat shape and, when viewed from the front, has a roughly rectangular plate shape extending left and right. The grille body 42A is preferably configured to be larger in the vertical, horizontal, and vertical directions than the front of the speaker box 25 when viewed from the front. The grille body 42A is positioned in front of the speaker body 28.

[0082] The grille body 42A has multiple hexagonal holes 42B that penetrate in the thickness direction in front of the speaker body 28. The hexagonal holes 42B are arranged in a hexagonal grid pattern, and a honeycomb structure (42C) is formed in the portion of the grille body 42A located in front of the speaker body 28. This honeycomb structure 42C allows the speaker grille 26 to have sufficient rigidity while effectively transmitting sound generated from the speaker body 28 to the seated person.

[0083] The edge of the grill body 42A is formed with a series of connecting holes 42D that penetrate in the front-to-back direction. The rear surface of the grill frame 41A is provided with connecting claws 41C that engage with the connecting holes 42D along the outer edge (see Figure 3). In this embodiment, the connecting claws 41C are provided on the rear surface of the grill frame 41A and protrude to the rear. When the connecting claws 41C protrude into and engage with the connecting holes 42D, the front grill 41 is connected to the front surface of the grill body 42A of the rear grill 42.

[0084] As shown in Figure 3, the speaker grille 26 is connected to the stay 21 via the mounting member 45. The mounting member 45 will be described first below.

[0101] The locking portion 66 is provided on the grill body 42A of the rear grill 42. The locking portion 66 includes a first locking portion 66A provided on the upper and lower rear edges of the grill body 42A, and a second locking portion 66B provided on the left and right rear edges of the grill body 42A.

[0102] The locking portion 68 is provided on the main portion 46 of the mounting member 45. The locking portion 68 includes a first locking portion 68A that engages with the first locking portion 66A and a second locking portion 68B that engages with the second locking portion 66B.

[0103] The first locking portions 66A are arranged in a line of three equal intervals in the left-right direction on the upper and lower edges of the main portion 46. The first locked portion 68A is provided on the grill body 42A at a position corresponding to the first locking portions 66A. In this embodiment, the first locking portion 66A is composed of a locking claw that protrudes rearward from the rear surface of the grill body 42A, and the first locked portion 68A is composed of a locking hole that penetrates the main portion 46. The first locking portion 66A is locked to the first locked portion 68A when the locking claw protrudes into the locking hole and catches on the edge that defines the locking hole.

[0104] Each of the second locking portions 66B protrudes rearward and passes near the edge of the through hole 48 of the mounting member 45. As shown in Figures 8(A) and 8(B), each of the second locking portions 66B has a main surface facing left to right and includes a flat inner piece 66C extending rearward and a locking recess 66D that is recessed at the tip of the outer surface of the inner piece 66C.

[0105] The second locking portion 68B is provided on the edge of the through hole 48. As shown in Figures 8(A) and 8(B), the second locking portion 68B comprises an outer piece 68C that protrudes rearward along the outer surface of the inner piece 66C, and a locking projection 68D provided at the tip of the outer piece 68C that protrudes into the locking recess 66D. The outer piece 68C and the inner piece 66C are joined when the locking projection 68D protrudes into the locking recess 66D. As a result, the left and right second locking portions 68B are locked to their respective second locking portions 66B.

[0106] As shown in Figure 8(A), the first locking portion 66A and the first locked portion 68A engage, and the second locking portion 66B engages with the second locked portion 68B, thereby connecting the speaker grille 26 to the mounting member 45 at its four edges (top, bottom, left, and right). As shown in Figure 9, the mounting member 45 is connected to the first wire member 33, so the speaker grille 26 is connected to the stay 21 via the mounting member 45. As a result, the speaker grille 26 is supported by the stay 21 at the front of the speaker box 25.

[0107] The front grille 41 is fixed to the mounting member 45 via the rear grille 42. In other words, the rear grille 42 functions as a fixing member for fixing the front grille 41 to the mounting member 45.

[0108] As shown in Figure 1, the speaker device 3 is fitted into the upper part of the seat back 6. The pad member 11 is positioned to cover the front and left and right sides of the seat back frame 10.

[0109] Figure 11 schematically shows the back surface of the surface material 12 provided on the upper part of the seat back 6. The surface material 12 is made of a sheet-like material such as cloth or leather. The surface material 12 comprises a lower surface 72 that covers the outer surface of the pad member 11 and an upper surface 74 that is coupled to the upper edge of the lower surface 72. The lower surface 72 is positioned so as to be in contact with the front surface of the pad member 11 on its back surface, and the upper surface 74 is positioned so as to cover the speaker device 3 (more specifically, the speaker grille 26).

[0110] The upper skin 74 includes a tongue portion 76, a latching hole 78 provided near the tongue portion 76, two openings 80 that are shaped to match the speaker body 28, and a plurality of locking holes 82 provided between the two openings 80.

[0111] The tongue portion 76 is located at the edge of the upper epidermis 74. More specifically, the tongue portion 76 is located at the edge of the upper epidermis 74 that is away from the lower epidermis 72. The tongue portion 76 is formed by folding back a band-shaped portion provided at the edge of the upper epidermis 74 and sewing it to form a bag-like structure. Thus, the tongue portion 76 can also be described as a bag-shaped sewn portion.

[0112] The latching holes 78 are holes that penetrate the upper epidermis 74. In this embodiment, two latching holes 78 are arranged side by side on the lower epidermis 72 side of the tongue portion 76.

[0113] The upper rear edge of the cylindrical portion 56 is provided with two latching portions 84 that protrude rearward. The upper surface 74 is connected to the mounting member 45 at the top by the latching holes 78 being latched onto the latching portions 84. This allows the surface material 12 and the mounting member 45 to be connected.

[0114] Each edge of the opening 80 is provided with an outwardly cut-out notch 86. In this embodiment, the notches 86 are provided on the left edge of the left opening 80 and on the right edge of the right opening 80.

[0115] The outer material 12 is provided with a reinforcing portion 88 that extends along the edge of the opening 80. The reinforcing portion 88 is preferably formed by joining a rigid member 12B, which is rigider than the fabric member 12A, to the fabric member 12A that constitutes the outer material 12. In this embodiment, the rigid member 12B is made up of a trim cord that extends along the edge of the opening 80, and the reinforcing portion 88 is formed by sewing the trim cord to the back surface (i.e., rear surface) of the fabric member 12A. In Figure 11, the sewing location between the rigid member 12B (trim cord) and the fabric member 12A is shown by a dashed line. In this way, when the reinforcing portion 88 is formed by joining a rigid material to the back surface of the fabric member 12A, the reinforcing portion 88 protrudes from the back surface of the fabric member 12A. By providing the reinforcing portion 88 along the edge of the opening 80, the edge of the opening 80 can be reinforced.

[0116] In this embodiment, the reinforcing portion 88 is positioned to avoid the notch 86 provided on the edge of the opening 80. Specifically, the reinforcing portion 88 extends from near the upper end of the notch 86 along the edge of the opening 80 to near the lower end of the notch 86.

[0117] The locking holes 82 are arranged in a row, one above the other. Each of the upper and lower rows has three locking holes 82. The locking holes 82 in each row are arranged at equal intervals in the left-right direction.

[0118] The outer material 12 is positioned such that the opening 80 overlaps the through hole 48, and the locking hole 82 overlaps the first locked portion 68A from the front. The speaker grille 26 is connected to the mounting member 45 by the first locking portion 66A passing through the locking hole 82 and being locked to the first locked portion 68A (see Figure 5), and the second locking portion 66B passing through the notch 86 and being locked to the second locked portion 68B. At this time, as can be seen from Figures 3 and 5, the outer material 12 is sandwiched between the speaker grille 26 and the mounting member 45 at the edge of the opening 80 and the portion between the two openings 80, respectively. The reinforcing portion 88 of the outer material 12 is housed in the receiving recess 52, and its movement in the direction along the main portion 46 of the mounting member 45 is restricted.

[0119] As shown in Figure 12, the pad member 11 comprises a front pad portion 11A positioned on the front side of the seat back frame 10, a left pad portion 11B positioned on the left side of the seat back frame 10, and a right pad portion 11C positioned on the right side of the seat back frame 10. The front pad portion 11A is located in front of the speaker device 3, the left pad portion 11B is located to the left of the speaker device 3, and the right pad portion 11C is located to the right of the speaker device 3. As a result, the speaker device 3 is surrounded by the pad member 11 from the front and both sides. That is, the pad member 11 is roughly cylindrical with an upward opening and a slit on its rear surface, and is housed in its opening in the speaker device 3. This configuration allows for cushioning on the front and left and right sides of the vehicle seat 1. The left pad portion 11B and the right pad portion 11C correspond to the pad sides located on the left and right sides of the seat back frame 10, respectively.

[0120] The front part 11A of the pad comprises a roughly plate-shaped base part 90 having a surface facing in the front-rear direction, and a hooking part 92 provided at the upper end of the base part 90. The hooking part 92 has a main surface facing in the up-down direction and is composed of a plate piece extending rearward from the upper edge of the base part 90. As a result, the hooking part 92 has a flange shape extending rearward. The hooking part 92 abuts against the first wire member 33 from above at its rear and is hooked onto the first wire member 33. Because the hooking part 92 is composed of a plate piece having a surface facing in the up-down direction, it can make good contact with the upper surface of the first wire member 33 and hook onto the first wire member 33 effectively.

[0121] It is preferable that at least two hook portions 92 are spaced apart on the pad member 11. In this embodiment, as shown in Figure 12, three hook portions 92 are provided on the upper edge of the front portion 11A of the pad, spaced apart from each other on the left and right. Hereinafter, the hook portion 92 located at the left end will be referred to as the left hook portion 92A, the hook portion 92 located in the center as the central hook portion 92B, and the hook portion 92 located at the right end as the right hook portion 92C.

[0122] The left hook portion 92A, the central hook portion 92B, and the right hook portion 92C are each roughly rectangular in shape when viewed from above. The front-to-back width (width in the front-to-back direction) of the left hook portion 92A, the front-to-back width of the central hook portion 92B, and the front-to-back width of the right hook portion 92C are equal to each other. The left-to-right width (width in the left-to-right direction) of the left hook portion 92A is equal to the left-to-right width of the right hook portion 92C. The left-to-right width of the central hook portion 92B is greater than the left-to-right width of the left hook portion 92A and the left-to-right width of the right hook portion 92C.

[0123] The left hook portion 92A, the central hook portion 92B, and the right hook portion 92C each extend rearward from the upper edge of the base portion 90 and abut against the lower frame 33C (left and right frame portions) of the first wire member 33 from above. In this embodiment, the vertical frame 35A of the second wire member 35 is connected to the lower frame 33C. The second wire member 35 is directly connected to the first wire member 33 and functions as a connection portion that allows the speaker box 25 to be supported by the first wire member 33. Two slits 94 are formed in the central hook portion 92B to avoid the vertical frame 35A. Each slit 94 is formed by cutting out from the front end toward the rear. The vertical frame 35A of the central hook portion 92B is inserted and passes through the slits 94.

[0124] As shown in Figure 5, the base portion 90 is provided with a projection 96 that protrudes rearward below the hook portion 92. The projection 96 works in cooperation with the hook portion 92 to clamp the first wire member 33. In this embodiment, an inclined surface 96A that slopes downward toward the rear is provided on the upper surface of the projection 96. The inclined surface 96A guides the first wire member 33 between the hook portion 92 and the projection 96 when assembling the pad member 11, and plays a role in improving the ease of assembly of the pad member 11.

[0125] Furthermore, the protruding wall 48A provided in the left through-hole 48 may abut against the upper surface of the left hook portion 92A, and the left hook portion 92A may be held between the protruding wall 48A and the first wire member 33. Similarly, the protruding wall 48A provided in the right through-hole 48 may abut against the upper surface of the right hook portion 92C, and the right hook portion 92C may be held between the protruding wall 48A and the first wire member 33.

[0126] Next, a method for manufacturing the vehicle seat 1 will be described. The method for manufacturing the vehicle seat 1 includes the steps of preparing a seat frame 22 including a stay 21, connecting a support member 31 to the stay 21, assembling a pad member 11 and a surface material 12 to the seat frame 22, attaching a speaker box 25 and a mounting member 45 to the support member 31, hooking the hooking holes 78 of the surface material 12 to the hooking portions 84 of the mounting member 45, and connecting the speaker grille 26 to the mounting member 45 while sandwiching the surface material 12.

[0127] In the step of hooking the locking hole 78 onto the locking part 84, the worker manufacturing the vehicle seat 1 should grasp the tongue-shaped part 76 and pull it upward and backward to hook the locking hole 78 onto the locking part 84. In this way, using the tongue-shaped part 76 makes it easier to manufacture the vehicle seat 1.

[0128] The step of assembling the pad member 11 to the seat frame 22 includes the step of hooking the left hook portion 92A, the central hook portion 92B, and the right hook portion 92C onto the first wire member 33, respectively.

[0129] Next, the effects of the vehicle seat 1 configured in this way will be explained. The edge of the opening 80 of the surface material 12 is sandwiched between the speaker grille 26 and the mounting member 45. As a result, the edge of the opening 80 is stably fixed to the seat frame 22, and it is possible to prevent the edge of the opening 80 of the surface material 12 from peeling off.

[0130] Furthermore, the locking portion 66 and the locked portion 68 are connected by passing through the locking holes 82 and openings 80 provided in the surface material 12. This prevents the surface material 12 from separating from the speaker grille 26 and the mounting member 45.

[0131] Furthermore, the reinforcing portion 88 of the surface material 12 is housed in the receiving recess 52. Therefore, the position of the surface material 12 can be accurately positioned so that the opening 80 overlaps with the through hole 48, and the surface material 12 can be placed in the appropriate position. In addition, displacement of the surface material 12 can be prevented.

[0132] A notch 86 is provided on the outer edge of the opening 80, and the second locking portion 66B extends rearward through the notch 86 and connects to the second locked portion 68B. On the other hand, the reinforcing portion 88 extends along the outer circumference of the opening 80 at a position that avoids the notch 86, and the reinforcing portion 88 is not provided in the portion of the surface material 12 near the notch 86. Therefore, when the second locking portion 66B is passed through the notch 86, the portion of the surface material 12 near the notch 86 can be easily deformed, so the second locking portion 66B and the second locked portion 68B can be easily engaged.

[0133] Support pieces 54 extending inward into the sheet are provided on both the left and right edges of the central hole 50. As shown in Figure 5, the support pieces 54 are located behind the surface material 12 (i.e., on the inside of the sheet). Therefore, by providing the support pieces 54, the rearward movement of the surface material 12 is restricted, preventing sagging of the surface material 12.

[0134] Support pieces 54 are provided on the left and right edges of the central hole 50, respectively. This restricts the rearward movement of the surface material 12 at both the left and right edges of the central hole 50, thereby effectively preventing sagging of the surface material 12.

[0135] The speaker grille 26 is attached to a mounting member 45 which is connected to a first wire member 33. That is, the speaker grille 26 is connected to the first wire member 33 via the mounting member 45. The first wire member 33 is connected to a stay 21, which is connected to the upper part of the seat back frame 10. Therefore, the speaker grille 26 is supported by the seat back frame 10 via the mounting member 45 and the first wire member 33.

[0136] The speaker box 25 is connected to the first wire member 33 via the second bracket 36. As a result, the speaker box 25 is connected to the stay 21 via the first wire member 33 without the need for a mounting member 45.

[0137] On the other hand, the airbag module 18 is attached to the lower part of the seatback frame 10. This allows the speaker grille 26 and speaker box 25 to be positioned so as not to obstruct the deployment of the airbag.

[0138] As shown in Figure 12, the pad member 11 is provided with a hook portion 92 that can be hooked onto the first wire member 33. The hook portion 92 is hooked onto the first wire member 33, and the pad member 11 is connected to the first wire member 33. In this way, by connecting the pad member 11 to the first wire member 33, which connects the speaker device 3 to the seat back frame 10, it is not necessary to provide a separate wire member or the like to support the pad member 11, and the speaker device 3 and the pad member 11 can be supported with a simple configuration.

[0139] The hook portion 92 is flange-shaped and extends from the base portion 90. Therefore, the structure for hooking onto the wire member is simple. In addition, the pad member 11 is provided with three spaced-apart hook portions 92, so that the pad member 11 can be stably supported by the first wire member 33. Furthermore, since the hook portions 92 are provided on the upper edge of the pad member 11, the pad member 11 can be hooked onto the first wire member 33 well, and the pad member 11 can be well supported by the first wire member 33.

[0140] In this embodiment, the width of the central hook portion 92B is configured to be larger than that of both the left hook portion 92A and the right hook portion 92C. Therefore, the pad member 11 can be well supported by the first wire member 33 between the hook portions 92 located at both ends.

[0141] As shown in Figure 5, the pad member 11 is provided with a projection 96 that protrudes rearward below the hooking portion 92. The first wire member 33 is held between the projection 96 and the hooking portion 92. As a result, the pad member 11 is more strongly bonded to the first wire member 33, and the pad member 11 is well supported by the first wire member 33.

[0142] As shown in Figure 12, a slit 94 is formed in the central hook portion 92B for passing through the vertical frame 35A. The formation of this slit 94 allows the central hook portion 92B and the vertical frame 35A to be positioned so that they overlap front to back, thereby enabling a compact configuration of the vehicle seat 1.

[0143] This concludes the description of specific embodiments, but the present invention is not limited to the above embodiments and can be broadly modified and implemented.

[0144] In the above embodiment, the locking portion 66 was provided so as to protrude from the rear grille 42 toward the mounting member 45, but the embodiment is not limited to this. The locking portion 66 may protrude from either the rear grille 42 or the mounting member 45 toward the other, and the locked portion 68 may be provided toward the other. In the above embodiment, the first locking portion 66A was composed of a locking claw and the first locked portion 68A was composed of a locking hole, but the first locking portion 66A may be composed of a locking hole and the first locked portion 68A may be composed of a locking claw. Similarly, the second locking portion 66B was provided with a recess and the second locked portion 68B was provided with a protrusion that enters the recess of the second locking portion 66B, but the second locking portion 66B may be provided with a protrusion and the second locked portion 68B may be provided with a recess that receives the protrusion of the second locking portion 66B.

[0145] In the above embodiment, the reinforcing portion 88 was formed by bonding a material harder than the fabric member 12A to the back side of the fabric member 12A, but it may also be formed by bonding a material harder than the fabric member 12A to the front side of the fabric member 12A. In this case, a receiving recess 52 for receiving the reinforcing portion 88 may be provided on the rear surface of the rear grille 42.

[0146] In the above embodiment, an example is described in which the pad member 11 is provided with three hooking portions 92, but the embodiment is not limited to this, and it is sufficient for the pad member 11 to be provided with at least one hooking portion 92. In order to stably support the pad member 11 on the wire member, it is preferable that the pad member 11 is provided with two or more hooking portions 92 spaced apart from each other.

[0147] In the above embodiment, the hook portion 92 was provided only on the front portion 11A of the pad, but the hook portion 92 only needs to be provided on at least one of the front portion 11A of the pad, the left portion 11B of the pad, and the right portion 11C of the pad.

[0148] Figure 13 shows an example in which the hook portion 92 is provided on the front portion 11A of the pad, the left portion 11B of the pad, and the right portion 11C of the pad.

[0149] In the example shown in Figure 13, an annular wire 100 is provided on the upper part of the seat back frame 10, forming a ring when viewed from above. The annular wire 100 is preferably made of a metal rod-shaped member or pipe material that has been bent and deformed to form a ring.

[0150] The hook portion 92 provided on the front part 11A of the pad extends rearward and contacts the upper surface of the annular wire 100. The hook portion 92 provided on the left part 11B of the pad extends to the right (i.e., inward to the left and right) and contacts the upper surface of the annular wire 100. The hook portion 92 provided on the right part 11C of the pad extends to the left (i.e., inward to the left and right) and contacts the upper surface of the annular wire 100. As a result, the pad member 11 is hooked onto the annular wire 100 from the front, right, and left sides, respectively, and secured in place.

[0151] In this way, by providing hooks 92 on the left side 11B and right side 11C of the pad located on the left and right sides of the seat back frame 10, the pad member 11 can be connected to the annular wire 100 from the left and right directions. Therefore, the pad member 11 can be stably supported on the seat back frame 10 from the left and right directions.

[0152] As shown in Figure 13, the pad member 11 may include a rear pad portion 11D positioned on the rear side of the seat back frame 10. The rear pad portion 11D may be provided on the rear side of the left side of the seat back frame 10 and on the rear side of the left side of the seat back frame 10, respectively. The rear pad portion 11D may also be provided with a hook portion 92 extending forward from its upper end, contacting the upper surface of the annular wire 100 and hooking onto the annular wire 100.

[0153] In the above embodiment, the protrusion 96 was configured to bulge out of the pad member 11 below the first wire member 33, but the protrusion 96 may be configured in any way as long as it cooperates with the hooking portion 92 to clamp the first wire member 33. For example, as shown in Figure 14, the protrusion 96 may have an inclined surface 96A that slopes downward toward the rear on the upper side, and may be in the shape of a plate that protrudes backward below the first wire member 33.
