[0001] The present invention relates to a vehicle seat.

Background Art

[0002] The following Patent Document 1 discloses a technique related to a seat back provided with a seat back pad and a seat back wire. In this prior art, in a seat cover (seat skin) that covers the seat back, a front suspension wire is provided in a front cover portion that covers the front side of the seat back, and a back suspension wire is provided in a back cover portion that covers the back side of the seat back. The front wire portion and the back wire portion are connected by a connecting wire portion.

[0003] Thus, by connecting the front suspension wire and the back suspension wire to a common seat back wire (connecting wire), in this prior art, it is not necessary to separately provide the front seat back wire and the back seat back wire at predetermined positions with respect to the seat back, and it is possible to suppress an increase in the manufacturing cost of the seat back. <0000​​​​​​​​​​​​​​​​​​​​​​​

[0006] In consideration of the above facts, the present invention aims to provide a vehicle seat that can reduce the cost of attaching the seat upholstery. [Means for solving the problem]

[0007] A vehicle seat according to the first embodiment comprises a seat surface that covers the seat pad of the vehicle seat from the front side to the back side, and has a first suspension portion provided in a groove formed on the front side of the seat pad and arranged in a direction substantially perpendicular to the thickness direction of the seat pad, and a second suspension portion provided on the back side of the seat pad; and a clip that penetrates from the front side to the back side of the seat pad, and has the first suspension portion engaged from the front side of the seat pad when tension is applied to the seat surface by suspension by the first suspension portion on the front side of the seat pad, and the second suspension portion engaged from the back side of the seat pad when tension is applied to the seat surface by suspension by the second suspension portion on the back side of the seat pad.

[0008] The vehicle seat according to the first embodiment includes a seat cover and a clip. The seat cover covers the seat pad of the vehicle seat from the front side to the back side, and the seat cover is provided with a first suspension portion and a second suspension portion. The first suspension portion is housed in a groove formed on the front side of the seat pad and along a direction substantially perpendicular to the thickness direction of the seat pad, and the second suspension portion is provided on the back side of the seat pad.

[0009] On the other hand, the clip is provided so as to penetrate from the front side to the back side of the seat pad. The first suspension part engages with the clip from the front side of the seat pad while tension is applied to the seat surface by suspension by the first suspension part on the front side of the seat pad. Also, the second suspension part engages with the clip from the back side of the seat pad while tension is applied to the seat surface by suspension by the second suspension part on the back side of the seat pad.

[0010] In other words, in this embodiment, the first suspension portion and the second suspension portion are engaged with a single clip, thereby enabling tension to be applied to the seat surface on the front side of the seat pad and to the seat surface on the back side of the seat pad.

[0011] Therefore, in this embodiment, a wire for suspending the seat surface is not required in the seat pad, and tension can be applied to the seat surface on both the front and back sides of the seat pad with a single clip, thus reducing costs.

[0012] Furthermore, in this embodiment, a higher tension can be obtained by suspending the seat surface from each other on the front and back sides of the seat pad via a single clip through the first suspension portion and the second suspension portion.

[0013] Thus, in this embodiment, it is possible to apply high tension to the seat surface on the back side of the vehicle seat, making it possible to give the back side of the vehicle seat a so-called inverse shape (a shape that is convex toward the front side of the vehicle seat), and making it possible to secure the required knee room on the rear side of the vehicle seat.

[0014] In this embodiment, the "seat pad" is applicable to both the seat back and the seat cushion, respectively. The "front and back sides of the seat pad" refer, for example, to the front and back sides of the seat pad in the case of a seat back, and to the top and bottom sides of the seat pad in the case of a seat cushion. Furthermore, the "grooves formed along a direction substantially perpendicular to the thickness direction of the seat pad" are formed along the vertical and horizontal directions of the seat in the case of a seat back, and along the front-to-back and horizontal directions of the seat in the case of a seat cushion.

[0015] In the second embodiment of the vehicle seat, the clip is molded integrally with the seat pad, as in the vehicle seat according to the first embodiment.

[0016] In the vehicle seat according to the second embodiment, the clip is molded integrally with the seat pad, eliminating the need to assemble the clip to the seat pad, resulting in improved workability.

[0017] A vehicle seat according to the third embodiment is a vehicle seat according to the first or second embodiment, wherein the first suspension portion includes a mounting member to which the seat surface is attached, the second suspension portion includes a suspension member provided on the seat surface and a locking member provided at the tip of the suspension member, and the clip is configured to include an engaging portion to which the mounting member is engaged and a locked portion to which the locking member is locked.

[0018] In the third embodiment of the vehicle seat, the first suspension portion includes a mounting member, to which the seat surface is attached. The second suspension portion includes a suspension member and a locking member. The suspension member is provided on the seat surface, and the locking member is provided at the tip of the suspension member. The clip, on the other hand, includes an engaging portion and a locked portion. The mounting member, which constitutes part of the first suspension portion, engages with the engaging portion, and the locking member, which constitutes part of the second suspension portion, locks with the locked portion.

[0019] In other words, tension is applied to the seat upholstery on the front side of the seat pad by engaging the mounting member of the first suspension portion of the seat upholstery, which corresponds to the front side of the seat pad, with the engaging portion of the clip. Then, tension is applied to the seat upholstery on the back side of the seat pad by locking the locking member of the second suspension portion of the seat upholstery, which corresponds to the back side of the seat pad, with the locking portion of the clip.

[0020] Thus, since the first and second suspension parts of the seat cover are simply engaged at one end (engaging part) and the other end (locking part) of the clip, the work efficiency is better compared to the hog-ringing process used to suspend the seat cover.

[0021] A vehicle seat according to the fourth embodiment is a vehicle seat according to any one of the first to third embodiments, wherein the clip is molded integrally with the seat pad and further includes a connecting portion that connects the engaging portion and the locked portion, the connecting portion being embedded in the seat pad, and the engaging portion and the locked portion being exposed from the seat pad.

[0022] In the vehicle seat according to the fourth embodiment, the clip further includes a connecting portion that connects the engaging portion and the locked portion, and the connecting portion is embedded in the seat pad. On the other hand, the engaging portion and the locked portion are exposed from the seat pad.

[0023] In other words, since the engaging portion and the locked portion are visible, workability is improved when engaging the mounting member of the first suspension portion with the engaging portion, or when locking the locking member of the second suspension portion with the engaged portion.

[0024] The vehicle seat according to the fifth aspect is the vehicle seat according to any one of the first to fourth aspects, wherein the attachment member includes an attachment portion to which the seat skin is attached, and an engaged portion provided at a tip end portion of the attachment portion and having an engagement recess formed on a side surface thereof for engaging the engaging portion. The engaging portion includes an engaging claw that engages with the engagement recess, and a housing portion that houses the engaged portion in a state where the engaging claw is engaged with the engagement recess.

[0025] In the vehicle seat according to the fifth aspect, the attachment member includes an attachment portion and an engaged portion, and the seat skin is attached to the attachment portion. On the other hand, the engaged portion is provided at a tip end portion of the attachment portion, and an engagement recess for engaging the engaging portion is formed on a side surface of the engaged portion.

[0026] On the other hand, the engaging portion includes an engaging claw and a housing portion, and the engaging claw engages with the engagement recess. The housing portion is configured to house the engaged portion in a state where the engaging claw is engaged with the engagement recess. Thus, since it is only necessary to engage the engaging claw formed on the clip with the engagement recess formed on the engaged portion of the attachment member provided on the first hanging portion, the workability is good.

[0027] The vehicle seat according to the sixth aspect is the vehicle seat according to any one of the first to fifth aspects, wherein the locked portion includes a locked hole that penetrates along the attachment direction of the attachment member with respect to the seat skin.

[0028] In the vehicle seat according to the sixth aspect, the locked portion includes a locked hole that penetrates along the attachment direction of the attachment member with respect to the seat skin. Since the seat skin is provided on the first hanging portion housed in the groove formed on the surface side of the seat pad, the attachment direction of the attachment member with respect to the seat skin is a direction along the width direction of the groove, which is substantially orthogonal to the extending direction of the groove.

[0029] In other words, the locking hole penetrates the groove along its width. The locking member, provided at the tip of the suspension member on the second suspension section, is locked to the locking hole along its width. Therefore, the direction in which tension is applied to the sheet surface and the direction in which the locking member is locked to the locking hole are the same, resulting in good workability.

[0030] The seventh embodiment of the vehicle seat is a vehicle seat according to any one of the first to sixth embodiments, wherein the clip is molded integrally with the seat pad, and the connecting portion is configured to include a plurality of through holes that penetrate in a direction substantially perpendicular to the thickness direction of the seat pad.

[0031] In the vehicle seat according to the seventh embodiment, the clip is molded integrally with the seat pad, and a plurality of through holes are formed in the connecting portion that constitutes part of the clip, in a direction substantially perpendicular to the thickness direction of the seat pad. Since the clip is positioned along the thickness direction of the seat pad, the sheet pad is filled into the through holes by forming a plurality of through holes in the connecting portion in a direction substantially perpendicular to the thickness direction of the seat pad. As a result, the connecting portion is prevented from coming off in the thickness direction of the seat pad.

[0032] The eighth embodiment of the vehicle seat is a vehicle seat according to any one of the first to seventh embodiments, wherein the seat pad is applied to a seat back pad used in a seat back that supports the upper body of a seated occupant seated on the seat cushion from the rear side of the seat.

[0033] In the eighth embodiment of the vehicle seat, the seat pad can enjoy the effects obtained in any one of the first to seventh embodiments of the vehicle seat in the seat back. [Effects of the Invention]

[0034] As described above, the vehicle seat according to the present invention can reduce the cost of attaching the seat cover. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0036] Hereinafter, a vehicle seat according to an embodiment of the present invention will be described with reference to the drawings. In the drawings, arrow FR indicates the forward direction in the seat's longitudinal direction, arrow UP indicates the upward direction in the seat's vertical direction, and arrow RH indicates the right direction in the seat's width direction. Hereafter, when simply referring to the front-rear, left-right, and up-down directions, unless otherwise specified, they refer to the front-rear direction of the seat, the left-right direction in the seat's width direction, and the up-down direction of the seat.

[0037] (Vehicle seat configuration) First, let me explain the configuration of the vehicle seats.

[0038] Figure 1 shows a rear view of a seat back 12 in a vehicle seat 10 according to this embodiment, which supports the back of a seated occupant seated on a seat cushion (not shown) from the rear side of the seat. A headrest (not shown) is provided above the seat back 12 to support the head of the seated occupant.

[0039] As shown in Figure 2, the seat back 12 is composed of a seat back frame 14 which forms the skeletal member of the seat back 12 and has a rectangular frame shape when viewed from the front, a seat back pad (seat pad) 16 which covers the seat back frame 14 and elastically supports the seated occupant, and a seat back surface (seat surface) 18 which extends from the front (surface) 16A to the back (back) 16B of the seat back pad 16.

[0040] The seat back frame 14 is composed of left and right side frames 14A that extend vertically on both sides of the seat back 12 in the left-right direction, an upper frame (not shown) that connects the upper ends of the left and right side frames 14A in the left-right direction, and a lower frame (not shown) that connects the lower ends of the left and right side frames 14A in the left-right direction.

[0041] The left and right side frames 14A and the lower frame are made of, for example, press-formed metal plates, and the upper frame is made of, for example, metal pipes. The upper frame and the lower frame are fixed to the left and right side frames 14A by joining, such as by welding.

[0042] The seat back pad 16 is made of a foam material such as urethane foam and is supported by the seat back frame 14. The seat back pad 16 also includes a center portion 22 located in the center of the seat width direction and a pair of side portions 24 located on both sides of the center portion 22 in the seat width direction, with the side portions 24 protruding forward of the seat from the center portion 22.

[0043] Furthermore, a groove 26 is recessed between the center portion 22 and the pair of side portions 24, extending along the vertical direction of the seat on the front surface 16A side of the seat back pad 16. Although not shown in the figures, the groove 26 may also extend along the width direction of the seat in the center portion 22.

[0044] The seat back surface 18 is composed of multiple surface pieces (here, surface pieces 18A and 18B). For example, the mounting portion 30 (see Figure 6) of the mounting member 28 (see Figure 6), which will be described later and constitute part of the first suspension portion 27, is attached to adjacent surface pieces 18A and 18B.

[0045] Regarding the attachment of the skin pieces 18A and 18B to the mounting portion 30 here, the skin pieces 18A and 18B may be joined together beforehand by sewing, welding, adhesive, etc. Alternatively, one of the skin pieces 18A and 18B may be attached to the mounting portion 30 by welding, etc., and then the other skin piece may be joined to the other skin piece by sewing, etc. Also, the seat back skin 18 does not necessarily have to be composed of multiple skin pieces 18A and 18B, and may be composed of a single skin. In this case, when the seat back skin 18 is composed of a single skin, the mounting portion 30 is attached to the seat back skin 18 by grasping a part of the seat back skin 18.

[0046] As described above, with adjacent skin pieces 18A and 18B integrated together, skin piece 18A covers the front side of the center portion 22 of the seat back pad 16, and skin piece 18B covers the side portion 24 of the seat back pad 16 from the front to the back.

[0047] In this embodiment, a clip 32 is provided for suspending the seat back surface 18 to the inside of the seat back pad 16.

[0048] As shown in Figures 4, 5A, and 5B, as an example, the clip 32 has a substantially rectangular shape in plan view, and an engaging portion 34 is provided at one end of the clip 32 in the longitudinal direction, which is located on the front side of the seat back pad 16 (see Figure 6). A locking portion 36 is provided at the other end of the clip 32 in the longitudinal direction, which is located on the rear side of the seat back pad 16. Furthermore, a connecting portion 38 is provided in the longitudinal center of the clip 32, and the engaging portion 34 and the locking portion 36 are connected by this connecting portion 38.

[0049] The engaging portion 34 is formed in a substantially U-shape, and engaging claws 40 are formed at the tips of a pair of opposing side walls 34A, each protruding in a direction toward each other. The pair of side walls 34A and the bottom wall 34B form a housing portion 42, which will be described later. The locking portion 36 is formed in a substantially T-shape, and a rectangular locking hole 46 penetrates the center of the vertical wall portion 44 formed along the longitudinal direction of the clip 32.

[0050] As shown in Figure 6, the clip 32 is molded integrally with the seat back pad 16, and the connecting portion 38 is embedded within the seat back pad 16. The connecting portion 38 is rectangular in shape, and has two through holes 48 formed along the longitudinal direction (thickness direction of the seat back pad 16) and the width direction of the clip 32.

[0051] The through-hole 48 is rectangular in shape with the thickness direction of the seat back pad 16 as its longitudinal direction, and penetrates along the front surface 16A of the seat back pad 16 (along a direction substantially perpendicular to the thickness direction of the seat back pad 16). The connecting portion 38 is provided approximately in the center of the height direction of the engaging portion 34 and the locked portion 36, as shown in Figure 5B.

[0052] As shown in Figure 6, the engaging portion 34 and the locked portion 36 are set to be exposed from the seat back pad 16. In other words, the engaging portion 34 is located in a groove 26 formed on the front surface 16A side of the seat back pad 16, and the locked portion 36 is located on the back surface 16B side of the seat back pad 16.

[0053] As mentioned above, the seat back surface 18 is composed of a plurality of surface pieces 18A and 18B, and mounting members 28 are attached to adjacent surface pieces (in this case, surface pieces 18A and 18B). The mounting members 28 are composed of a mounting portion 30 and an engaged portion 50. The mounting portion 30 is attached to adjacent surface pieces 18A and 18B, and the engaged portion 50 is provided at the tip of the mounting portion 30. An engaging recess 50A is formed on the side surface of the engaged portion 50, into which an engaging claw 40 formed on the engaging portion 34 of a clip 32 positioned in the groove portion 26 of the seat back pad 16 engages.

[0054] With the mounting portion 30 attached to the adjacent surface pieces 18A and 18B of the mounting member 28, as shown in Figure 7, the engaging claw 40 of the clip 32 is engaged with the engaging recess 50A formed in the engaged portion 50, thereby covering the front surface 16A of the seat back pad 16 with the seat back surface 18.

[0055] Here, as shown in Figure 2, the surface piece 18B to which the mounting member 28 is attached covers the side portion 24 of the seat back pad 16, and a strip-shaped suspension member 52, for example made of resin, which constitutes part of the second suspension portion 51, is sewn to the free end side of the surface piece 18B.

[0056] As shown in Figures 3 and 6, a hook (locking member) 54 is provided at the tip of the suspension member 52, and the hook 54 is insertable into a locking hole 46 formed in the locking portion 36 of the clip 32. As shown in Figures 3 and 7, when the hook 54 is inserted into the locking hole 46 and tension is applied to the skin piece 18B, the return portion 54A formed at the tip of the hook 54 is able to lock onto the peripheral portion 46A of the locking hole 46, so that the hook 54 does not come out of the locking hole 46.

[0057] In this way, the hook 54 provided at the tip of the suspension member 52 is engaged with the peripheral portion 46A of the locking hole 46 formed in the locking portion 36 of the clip 32, thereby covering the back surface 16B of the seat back pad 16 with the seat back upholstery 18.

[0058] In this embodiment, the hook 54 is locked into the locking hole 46 of the clip 32, thereby covering the back surface 16B of the seat back pad 16 with the seat back upholstery 18. However, the invention is not limited to this, as long as the back surface 16B of the seat back pad 16 can be covered with the seat back upholstery 18 via the clip 32.

[0059] For example, as a modified example, although not shown in the figures, a wire may be provided at the tip of the suspension member 52, and the suspension member 52 may be locked to the clip 32 by engaging the wire with the engagement hole 46 by hogling. Since the engagement hole 46 penetrates along the width direction of the groove 26, this is applicable when the wire is arranged along the longitudinal direction of the groove 26.

[0060] (Function and effect of vehicle seats) Next, we will explain the function and effects of vehicle seats.

[0061] As shown in Figures 2 and 3, the vehicle seat 10 in this embodiment includes a seat back cover 18 and clips 32. The seat back cover 18 covers the seat back pad 16 of the vehicle seat 10 from the front 16A side to the back 16B side, and the seat back cover 18 is provided with a first suspension portion 27 and a second suspension portion 51. The first suspension portion 27 is formed on the front 16A side of the seat back pad 16 and is housed in a groove 26 formed along a direction substantially perpendicular to the thickness direction of the seat back pad 16, and the second suspension portion 51 is provided on the back 16B side of the seat back pad 16.

[0062] On the other hand, the clip 32 is provided so as to penetrate the seat back pad 16 from the front side 16A to the back side 16B. With tension applied to the seat back surface 18 by the suspension by the first suspension part 27 on the front side 16A of the seat back pad 16, the first suspension part 27 engages with the clip 32 from the front side 16A of the seat back pad 16.

[0063] Furthermore, with respect to the clip 32, tension is applied to the seat back surface 18 by suspension by the second suspension part 51 on the back surface 16B side of the seat back pad 16, and the second suspension part 51 engages with the clip 32 from the back surface 16B side of the seat back pad 16.

[0064] In other words, in this embodiment, the first suspension portion 27 and the second suspension portion 51 are engaged with a single clip 32, thereby enabling tension to be applied to the seat back surface 18 on the front side 16A of the seat back pad 16 and also on the back side 16B of the seat back pad 16.

[0065] Therefore, in this embodiment, as in a comparative example, a wire for suspending the seat back surface 18 is not required in the seat back pad 16, and moreover, as in this embodiment, tension can be applied to the seat back surface 18 on both the front 16A and rear 16B sides of the seat back pad 16 by a single clip 32, thus reducing costs.

[0066] Furthermore, in this embodiment, a higher tension can be obtained by suspending the seat back surface 18 from each other on the front 16A side and the back 16B side of the seat back pad 16 via a single clip 32 through the first suspension part 27 and the second suspension part 51.

[0067] Thus, in this embodiment, it is possible to apply high tension to the seat back surface 18 on the back surface 11 (see Figure 3) side of the vehicle seat 10, so that the back surface 11 side of the vehicle seat 10 can be made inverse shape, and it is possible to secure the required knee room on the rear side of the vehicle seat 10.

[0068] Furthermore, in this embodiment, the clip 32 is molded integrally with the seat back pad 16, and tension is applied to the front 16A and back 16B sides of the seat back surface 18 by engaging the first suspension portion 27 and the second suspension portion 51 of the seat back surface 18 via the clip 32.

[0069] Generally, in order to apply tension to the seat back surface 18, a wire is integrally molded (insert wire) into the seat back pad 16 (not shown in the figure), and the suspension part is engaged with the insert wire. However, by applying this embodiment, it becomes possible to reduce the number of insert wires.

[0070] Furthermore, although not shown in the figures, when the insert wire is molded integrally with the seat back pad 16, it is necessary to set the insert wire in the mold used to mold the seat back pad 16. However, on the underside of the vehicle seat 10, the insert wire must be set behind the core of the mold, which makes setting the insert wire more difficult compared to setting it in front of the core. With the clip 32 in this embodiment, it is only necessary to set the clip 32 in the mold along the thickness direction of the seat back pad 16, thus improving workability.

[0071] Furthermore, in this embodiment, as shown in Figures 6 and 7, the seat back surface 18 is composed of a plurality of surface pieces 18A and 18B. The first suspension section 27 is composed of a mounting member 28, to which the surface pieces 18A and 18B are attached.

[0072] Furthermore, the second suspension section 51 is composed of a suspension member 52 and a hook 54. The suspension member 52 is provided on the seat back surface 18, and the hook 54 is provided at the tip of the suspension member 52.

[0073] On the other hand, the clip 32 is composed of an engaging portion 34 and a locked portion 36. The mounting member 28, which is part of the first suspension portion 27, is engaged with the engaging portion 34, and the hook 54, which is part of the second suspension portion 51, is locked to the locked portion 36.

[0074] In other words, when the mounting member 28 of the first suspension portion 27 of the seat back surface 18, which corresponds to the front surface 16A of the seat back pad 16, engages with the engaging portion 34 of the clip 32, tension is applied to the seat back surface 18 on the front surface 16A of the seat back pad 16.

[0075] Then, the hook 54 of the second suspension portion 51 of the seat back surface 18, which corresponds to the back surface 16B side of the seat back pad 16, is locked to the locking portion 36 of the clip 32, thereby applying tension to the seat back surface 18 on the back surface 16B side of the seat back pad 16.

[0076] Thus, in this embodiment, the first suspension portion 27 and the second suspension portion 51 of the seat back surface 18 are simply engaged at one end (engaging portion 34) and the other end (locked portion 36) of the clip 32, resulting in good workability.

[0077] Furthermore, in this embodiment, the clip 32 is configured to include a connecting portion 38 that connects the engaging portion 34 and the locked portion 36, and this connecting portion 38 is embedded in the seat back pad 16. On the other hand, the engaging portion 34 and the locked portion 36 are exposed from the seat back pad 16.

[0078] In other words, since the engaging portion 34 and the locked portion 36 are visible, it is easy to engage the mounting member 28 of the first suspension portion 27 with the engaging portion 34 and to lock the hook 54 of the second suspension portion 51 with the engaged portion 50.

[0079] In this embodiment, the mounting member 28 is composed of a mounting portion 30 and an engaged portion 50, and the surface pieces 18A and 18B are attached to the mounting portion 30. On the other hand, the engaged portion 50 is provided at the tip of the mounting portion 30, and an engaging recess 50A is formed on the side surface of the engaged portion 50 into which the engaging portion 34 is engaged.

[0080] The engaging portion 34 is composed of an engaging claw 40 and a housing portion 42, with the engaging claw 40 engaging with the engaging recess 50A. The housing portion 42 is designed to house the engaged portion 50 when the engaging claw 40 is engaged with the engaging recess 50A. In this way, the work is easy because it only requires engaging the engaging claw 40 formed on the clip 32 with the engaging recess 50A formed on the engaged portion 50 of the mounting member 28 provided on the first suspension portion 27.

[0081] Furthermore, in this embodiment, the locking portion 36 is configured to include a locking hole 46, and the locking hole 46 penetrates along the direction of connection in which adjacent surface pieces 18A and 18B are joined together. Since adjacent surface pieces 18A and 18B are provided in the first suspension portion 27 which is housed in a groove 26 formed on the front surface 16A side of the seat back pad 16, the direction of connection between adjacent surface pieces 18A and 18B is along the width direction of the groove 26, which is substantially perpendicular to the extending direction of the groove 26.

[0082] In other words, the locking hole 46 penetrates along the width direction of the groove 26. The hook 54 provided at the tip of the suspension member 52 provided on the second suspension part 51 is locked to the locking hole 46 along the width direction of the groove 26. In this embodiment, the direction in which tension is applied to the seat back surface 18 (direction of arrow A shown in Figure 6) and the direction in which the hook 54 is locked to the locking hole 46 are the same, resulting in good workability.

[0083] Furthermore, in this embodiment, the clip 32 is molded integrally with the seat back pad 16, and a plurality of through holes 48 are formed in the connecting portion 38 that constitutes a part of the clip 32, along a direction substantially perpendicular to the thickness direction of the seat back pad 16.

[0084] Since the clip 32 is positioned along the thickness direction of the seat back pad 16, a through hole 48 is formed in the connecting portion 38 in a direction substantially perpendicular to the thickness direction of the seat back pad 16, so that the seat back pad 16 fills the through hole 48. As a result, the connecting portion 38 is prevented from coming off in the thickness direction of the seat back pad 16.

[0085] In this embodiment, a clip 32 positioned in a groove 26 formed along the vertical direction of the seat has been described. However, the groove 26 may also be formed along the width direction of the seat, and as shown in Figure 1, the orientation in which the seat back upholstery 18 is suspended from the vehicle seat 10 may differ. In this case, the clip 32 is positioned in accordance with the orientation in which the seat back upholstery 18 is suspended.

[0086] Furthermore, in this embodiment, as shown in Figure 8A, the cross-sectional shape of the through-hole 48 is rectangular. Therefore, the partition wall 56 forming the through-hole 48 has a rectangular cross-sectional shape. Note that Figure 8A is a cross-sectional view taken along the CC line shown in Figure 5A. However, in this embodiment, it is sufficient that the connecting portion 38 can prevent the seat back pad 16 from coming off in the thickness direction, so the shape of the through-hole 48 is not limited to this.

[0087] For example, as shown in Figure 8B, in the connecting section 38, the through hole 58 may be formed such that the opening widens from the center of the through-direction toward the entrance side and then toward the exit side. In this case, the partition wall 60 forming the through hole 58 has a rhomboid cross-sectional shape.

[0088] Here, a slope 60A is formed on the partition wall 60. The seat back pad 16 will be filled into the through hole 58, and the slope 60A guides the seat back pad 16 (more precisely, the material of the seat back pad 16) toward the center of the through hole 58 in the direction of penetration during molding. This improves moldability.

[0089] Furthermore, as shown in Figure 6, the clip 32 only needs to penetrate from the front 16A side to the back 16B side of the seat back pad 16, suspending the first suspension portion 27 on the front 16A side of the seat back pad 16 and the second suspension portion 51 on the back 16B side of the seat back pad 16, so its shape is not limited to this.

[0090] Furthermore, although the seat back 12 has been described in this embodiment, it is not limited to this. It may also be applied to the seat cushion side, although this is not shown in the figures.

[0091] Furthermore, the vehicle seat 10 in the above embodiments may be applied not only to the front seat but also to the rear seat.

[0092] Furthermore, the present invention can be implemented with various modifications without departing from its essence. Of course, the scope of the present invention is not limited to the above embodiments or the above-described modifications. [Explanation of Symbols]
