[0001] The present invention relates to a vehicle seat in which a skin material is locked to a clip at a suspension portion, and a method for suspending the skin material.

Background Art

[0002] A vehicle seat may be provided with a suspension portion that is linearly recessed on the seating surfaces of the seat cushion and the seat back in order to maintain the external appearance shape.

[0003] For example, in Patent Document 1, a suspension groove is recessed in the seating surface of a pad, and a suspension member that is attached to the skin material and extends in the extending direction of the suspension groove is fixed to a clip fixed at the bottom of the suspension groove, thereby forming a structure of a suspension portion. The suspension member includes a skin connection portion (suspension cotton cloth) attached to the skin material, and a bulging portion (suspender) that is connected to the lower edge of the skin connection portion and bulges in the width direction of the suspension groove, and the bulging portion is locked to the clip.

[0004] Also, in Patent Document 2, regarding the same suspension portion as described above, a suspension member (pull-in member) is described that includes a skin connection portion (attachment portion) and a bulging portion that is locked to a clip, and the tip of the clip is inserted through a hole provided in the skin connection portion, thereby preventing the suspension member from coming off.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the structure described in Patent Document 1, there was a risk that the suspension member would shift in the direction of extension of the suspension groove, causing the outer ring shape of the vehicle seat to collapse. In the structure described in Patent Document 2, the tip of the clip is inserted into the hole, which not only prevents the suspension member from coming out of the suspension groove but also prevents it from shifting in the direction of extension of the suspension groove. However, it is necessary to precisely match the position of the tip of the clip with the position of the hole, and there was a risk that the position of the tip of the clip would shift from the hole due to construction errors. As a result, there was a risk that the outer ring shape of the vehicle seat would collapse if the tip of the clip was inserted into the hole at a position shifted from its original position in the direction of extension of the suspension groove, or if the tip of the clip was assembled without being inserted into the hole and then shifted away from the hole relative to its original position.

[0007] In view of the above background, the present invention aims to provide a vehicle seat equipped with a suspension section that can suppress displacement of the suspension member in the extending direction of the suspension groove and allows for easy position adjustment. [Means for solving the problem]

[0008] To solve the above problems, a vehicle seat (1) according to one aspect of the present invention comprises a pad (5) which is a cushion body having a suspension groove (8) recessed in the seating surface, a surface material (6) stretched on the seating surface of the pad, a base plate (12) embedded in the portion of the pad located at the bottom of the suspension groove, and a clip (9) which is erected from the base plate and includes a locking piece (13) having a locking claw (15) formed therein located in the suspension groove, and extending in the direction of extension of the suspension groove The suspension member (10, 32, 42, 52, 62) is strip-shaped and includes a skin connecting portion (16) connected to the skin material at one side edge, and a bulging portion (17) provided on the other side edge of the skin connecting portion so as to bulge in the width direction of the suspension groove and engage with the locking claw of the clip; and a displacement suppression member (11, 33, 43) fixed to the skin connecting portion by sewing and having end faces (19, 47) facing the extending direction so as to be able to abut the locking piece.

[0009] In this embodiment, the end face of the displacement suppression member abuts against the locking piece, thereby suppressing displacement of the suspension member in the extending direction. Furthermore, since the displacement suppression member is fixed to the surface connecting portion by sewing, its position relative to the clip can be easily adjusted.

[0010] In the above embodiment, the displacement suppression member (11) may be composed of a portion obtained by folding the longitudinal end of the suspension member (10) onto the main body (10a) of the suspension member.

[0011] According to this embodiment, since one component includes both the main body of the suspension member and the misalignment suppression member, an increase in the number of components can be suppressed.

[0012] In the above embodiment, it is preferable that the bulging portion (17) is separated between the main body (10a) and the displacement suppressing member (11).

[0013] In this embodiment, since the bulging portion is divided, it becomes easier to fold the displacement suppression member onto the main body of the suspension member.

[0014] In the above embodiment, the displacement suppression members (33, 43) may be separate from the suspension members (32, 42).

[0015] According to this embodiment, a simple configuration can be used to suppress misalignment of the suspension member in the extending direction of the suspension groove, and a suspension section that is easy to adjust can be constructed. Furthermore, misalignment suppression members can be provided not only for clips located near the ends in the extending direction of the suspension groove, but also for clips located in the intermediate section.

[0016] In the above embodiment, the displacement suppression member (33) may be made of the same material as the suspension member (32).

[0017] According to this embodiment, since the material of the displacement suppression member is the same as the material of the suspension member, the effort required to manufacture the displacement suppression member is reduced.

[0018] In the above aspect, the displacement suppressing member (43) may be configured to be overlapped on the suspension member (42) from both sides in the width direction so as to surround the bulging portion (17), and to have an opening (46) that defines the end face (47).

[0019] According to this aspect, displacement in both directions in the extending direction can be suppressed with a simple configuration.

[0020] One aspect of the present invention is a method of suspending the skin material (6) in the vehicle seat (1) of the above aspect, comprising a step of fixing the displacement suppressing member (11, 33, 43) to the skin connecting portion (16) by sewing, and a step of locking the bulging portion (17) to the locking claw (15).

[0021] According to this aspect, displacement of the suspension member in the extending direction can be suppressed by the displacement suppressing member, and since the displacement suppressing member is fixed to the skin connecting portion by sewing, the position with respect to the clip can be easily adjusted.

[0022] In the above aspect, the method further comprises a step of providing the displacement suppressing member (11) by folding the longitudinal end of the suspension member (10) onto the main body (10a) of the suspension member, and the fixing step includes fixing the skin connecting portion (16) of the displacement suppressing member to the skin connecting portion (16) in the main body by sewing.

[0023] According to this aspect, since one component includes a portion constituting the main body of the suspension member and a portion constituting the displacement suppressing member, an increase in the number of components can be suppressed.

[0024] In the above aspect, the step of providing the suspension member may preferably include dividing the bulging portion between the main body and the displacement suppressing member.

[0025] According to this aspect, since the bulging portion is divided, it becomes easy to fold the displacement suppressing member onto the main body of the suspension member.

[0026] In the above aspect, the step of providing the displacement suppressing member (11) includes dividing the bulging portion (17) between the main body (10a) and the displacement suppressing member.

[0027] According to this aspect, since the bulging portion is divided, it becomes easy to fold the displacement suppressing member onto the main body of the suspension member.

[0028] In the above aspect, the displacement suppressing members (33, 43) may be separate from the suspension members (32, 42).

[0029] According to this aspect, with a simple configuration, it is possible to suppress the displacement of the suspension member in the extending direction of the suspension groove, and a suspension portion that is easy to adjust the position can be configured. Also, not only clips arranged near the ends in the extending direction of the suspension groove but also clips arranged in the middle portion can be provided with displacement suppressing members.

[0030] In the above aspect, it may further include steps of creating a material including the skin connecting portion (16) and the bulging portion (17), and cutting the material to create the suspension member (32) and the displacement suppressing member (33), and the fixing step may include fixing the skin connecting portion of the displacement suppressing member to the skin connecting portion of the suspension member by sewing.

[0031] According to this aspect, since the material of the displacement suppressing member is the same as the material of the suspension member, the labor for creating the displacement suppressing member is less.

[0032] In the above embodiment, the displacement suppressing member (43) has an opening (46) defining the end face (47) and is flexible, and the fixing step may include overlapping the displacement suppressing member on both sides in the width direction of the suspension member (42) such that the portion of the bulging portion (17) that is locked to the locking claw (15) is exposed by the opening and surrounds the bulging portion, and fixing it to the skin connecting portion (16) by sewing.

[0033] According to this embodiment, a simple configuration can be used to suppress positional displacement in both directions in the extending direction. [Effects of the Invention]

[0034] According to the above embodiment, it is possible to suppress displacement of the suspension member in the extending direction of the suspension groove and to provide a vehicle seat equipped with a suspension section that is easy to adjust in position.

[0035] According to an embodiment in which the displacement suppression member is formed by folding the longitudinal end of the suspension member onto the main body (10a) of the suspension member, one component includes both the part that constitutes the main body of the suspension member and the part that constitutes the displacement suppression member, thus suppressing an increase in the number of components.

[0036] In this embodiment, if the bulging portion (17) is separated between the main body (10a) and the displacement suppression member (11), it becomes easier to fold the displacement suppression member onto the main body of the suspension member.

[0037] In the configuration in which the displacement suppression member is separate from the suspension member, displacement of the suspension member can be suppressed with a simple structure, a suspension section that is easy to adjust can be constructed, and the displacement suppression member can be provided not only for clips located near the ends in the extending direction of the suspension groove, but also for clips located in the intermediate part.

[0038] In this embodiment, if the displacement suppression member is made of the same material as the suspension member, the effort required to manufacture the displacement suppression member is reduced.

[0039] In an embodiment where the displacement suppression member is separate from the suspension member, if the displacement suppression member has an opening that defines its end face, displacement in both directions in the extending direction can be suppressed with a simple configuration.

[Modes for carrying out the invention]

[0041] Embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a perspective view of a vehicle seat 1 (hereinafter referred to as "seat 1") according to the first embodiment. The seat 1 comprises a seat cushion 2 supported by the vehicle body, a seat back 3 connected to the seat cushion 2, and a headrest 4 connected to the seat back 3. Each of the seat cushion 2, seat back 3, and headrest 4 comprises a pad 5 (see Figure 2) made of foamed resin such as foamed urethane, and a surface material 6 that covers the seating surface of the pad 5. On the surface of the seating surface of the seat cushion 2 and seat back 3, a plurality of linearly recessed suspension portions 7 are formed in the vertical and horizontal directions by the suspension of the surface material 6 within the pad 5.

[0042] Figure 2 shows the suspension portion 7 according to the first embodiment in a cross-section perpendicular to the extending direction of the suspension portion 7. As shown in Figures 1 and 2, the suspension portion 7 of the seat 1 comprises a pad 5 having a suspension groove 8 recessed in the seating surface, a surface material 6 stretched on the seating surface of the pad 5, a clip 9 fixed to the pad 5 so as to be positioned in the suspension groove 8, a suspension member 10 connected to the surface material 6 and locked to the clip 9, and a displacement suppression member 11 coupled to the suspension member 10.

[0043] Pad 5 is a cushion made of foamed resin such as polyurethane foam. The suspension groove 8 opens toward the seating surface and includes grooves that extend in the vertical direction (front-to-back direction in the seat cushion 2, and up-and-down direction in the seat back 3) and grooves that extend in the horizontal direction (left-to-right direction). The depth of the suspension groove 8 is approximately constant, and the bottom surface of the suspension groove 8 extends on a substantially flat plane. Hereafter, unless otherwise specified, the terms "extension direction" and "width direction" refer to the extension direction and width direction of the suspension groove 8.

[0044] The surface material 6 is a component made of leather, cloth, or the like that forms the surface of the seating surface of the seat 1 (see Figure 1).

[0045] The clip 9 includes a substrate 12 embedded in the pad 5 located at the bottom of the suspension groove 8, and a pair of locking pieces 13 erected from the substrate 12, and is, for example, an injection-molded product made of resin. The substrate 12 is generally flat and is positioned approximately parallel to the bottom surface of the suspension groove 8. The entire substrate 12 is embedded in the pad 5, but it may also be positioned so that both ends in the width direction are embedded in the pad 5, and the surface on which the locking pieces 13 are provided is exposed from the pad 5 in the center in the width direction. The pair of locking pieces 13 face each other in the width direction and include an erected portion 14 that is erected toward the opening of the suspension groove 8 from the portion of the substrate 12 that is inward in the width direction from the inner surface of the suspension groove 8, and a locking claw 15 that is formed to extend inward in the width direction from the tip of the erected portion 14 so as to be inclined toward the bottom surface of the suspension groove 8. The tips of the pair of locking claws 15 are spaced apart from each other in the width direction. The locking piece 13 is elastically deformable so as to increase the distance between the tips of the pair of locking claws 15. That is, the upright portion 14 is elastically deformable so as to bend or tilt so as to bend outward in the width direction, and / or the locking claws 15 are elastically deformable so as to bend or tilt so as to bend or tilt so as to bend closer to the upright portion 14.

[0046] The suspension member 10 is positioned within the suspension groove 8, and its longitudinal direction coincides with the extending direction of the suspension groove 8. The suspension member 10 includes a strip-shaped skin connecting portion 16 extending along the longitudinal direction of the suspension member 10, and a bulging portion 17 extending along the longitudinal direction of the suspension member 10 and connected to the side edge of the skin connecting portion 16. The skin connecting portion 16 is formed from a sewable material such as nonwoven fabric or woven fabric. The skin connecting portion 16 is connected to the skin material 6 by sewing at the side edge on the opening side of the suspension groove 8, and is connected to the bulging portion 17 at the side edge on the bottom side of the suspension groove 8. The bulging portion 17 has a shape that bulges in the width direction relative to the skin connecting portion 16 and is locked by the locking claws 15. Therefore, the clip 9 is configured such that the distance between the tips of a pair of locking claws 15 is narrower than the width of the bulging portion 17 before elastic deformation, and becomes wider than or equal to the width of the bulging portion 17 during elastic deformation. The bulge portion 17 is made of resin and formed by injection molding. The bulge portion 17 is connected to the skin connecting portion 16 by injection molding while the skin connecting portion 16 is mounted in the cavity of the mold. The suspension member 10 may also be made of resin in which the skin connecting portion 16 and the bulge portion 17 are molded together as a single unit.

[0047] Figure 3 is a perspective view showing the suspension member 10 and the displacement suppression member 11. As shown in Figures 2 and 3, the displacement suppression member 11 is formed by folding the longitudinal end of the suspension member 10 over the main body 10a of the suspension member 10 (the portion that engages with the clip 9 and extends substantially on a plane). The bulge 17 of the displacement suppression member 11 is positioned adjacent to the bulge 17 of the main body 10a of the suspension member 10. The surface connecting portion 16 of the displacement suppression member 11 is fixed to the surface connecting portion 16 of the main body 10a of the suspension member 10 by sewing at the side edge on the opening side of the suspension groove 8. Preferably, a notch 18 is provided between the main body 10a of the suspension member 10 and the displacement suppression member 11 on the side edge on the side where the bulge 17 of the suspension member 10 is provided, so that the longitudinal end of the suspension member 10 can be easily folded over as the displacement suppression member 11. The bulging portion 17 is divided into the main body 10a side and the displacement suppression member 11 side by the notch 18. Alternatively, the bulging portion 17 may be divided into the main body 10a side and the displacement suppression member 11 side by cutting the side edge of the suspension member 10 on the side where the bulging portion 17 is provided to create a slit (not shown).

[0048] Within the suspension groove 8 that receives the suspension member 10 of interest, the locking piece 13 of the clip 9, which is positioned closest to the displacement suppression member 11, is located on the central side in the extending direction relative to the displacement suppression member 11, and the end face 19 of the displacement suppression member 11 facing towards the central side in the extending direction can abut against the side surface of the locking piece 13 in the extending direction. The end face 19 may actually be in contact with the side surface of the locking piece 13, or there may be a gap between it and the side surface of the locking piece 13. If a gap is provided, the distance between the end face 19 and the side surface of the locking piece 13 is less than or equal to the length by which displacement of the suspension member 10 in the extending direction is permitted. The end face 19 of the displacement suppression member 11 can abut against the side surface of the locking piece 13 at the surface connecting portion 16 or the bulging portion 17, or both.

[0049] The method for suspending the surface material 6 in the suspension section 7 will be described below.

[0050] The worker inserts the clip 9 into a mold (not shown), and then injects foamed resin material into the mold and allows it to foam and harden, thereby forming a pad 5 in which the clip 9 is embedded.

[0051] The worker secures the suspension member 10 to the surface material 6 by sewing (reference numeral 20 indicates the thread for sewing). The displacement suppression member 11 is secured to the surface material 6 by sewing together with the main body 10a of the suspension member 10. Alternatively, the displacement suppression member 11 may be secured by sewing to the overlapping portion 16 of the surface material 6 and the surface connecting portion 16 of the surface material 10a of the suspension member 10 after the main body 10a of the suspension member 10 has been secured to the surface material 6 by sewing, or it may be secured by sewing to the surface connecting portion 16 of the surface material 10a of the suspension member 10 without being secured to the surface material 6 after the main body 10a of the suspension member 10 has been secured to the surface material 6, or it may be secured by sewing to the surface connecting portion 16 of the surface material 10a of the suspension member 10 first, and then secured to the surface material 6 together with the main body 10a.

[0052] Next, the worker inserts the suspension member 10 into the suspension groove 8 from the bulging portion 17 and presses the bulging portion 17 against the pair of locking claws 15 of the clip 9, thereby elastically deforming the locking piece 13 of the clip 9 so that the distance between the tips of the pair of locking claws 15 increases, and allowing the bulging portion 17 to pass between the tips of the pair of locking claws 15. After the bulging portion 17 has passed between the tips of the pair of locking claws 15, the locking piece 13 returns to its original shape, and the bulging portion 17 is locked to the locking claws 15.

[0053] The effects of the first embodiment will be explained with reference to Figures 1 to 3. When the bulging portion 17 is locked by the locking claw 15, the suspension member 10 is prevented from detaching from the suspension groove 8, and the suspension portion 7 is formed.

[0054] The end face 19 of the displacement suppression member 11 abuts against the extending side surface of the locking piece 13, thereby suppressing displacement of the suspension member 10 in the extending direction in the direction the end face 19 is facing. As a result, deformation of the appearance of the sheet 1 due to displacement of the suspension member 10 can be suppressed.

[0055] Since the means of fixing the displacement suppression member 11 to the main body 10a of the suspension member 10 is sewing, the sewing thread 20 can be unpicked and re-sewn, making it easy to adjust the position of the displacement suppression member 11 relative to the clip 9. Also, if the displacement suppression member 11 is fixed to the main body 10a of the suspension member 10 after the suspension member 10 is fixed to the surface material 6 of the main body 10a, the position of the displacement suppression member 11 relative to the clip 9 can be adjusted before fixing the displacement suppression member 11 to the main body 10a of the suspension member 10, making it easy to adjust the position of the displacement suppression member 11 relative to the clip 9. Furthermore, if the end face 19 of the displacement suppression member 11 extends beyond the side surface of the locking piece 13 of the clip 9 and is located closer to the center in the extending direction, the position of the displacement suppression member 11 can also be adjusted by cutting off the portion that extends beyond the side surface.

[0056] Next, a second embodiment of the present invention will be described with reference to Figure 4. In this description, components common to the first embodiment will be omitted from description and will be denoted by the same reference numerals. Similarly, in the description of the third embodiment and subsequent embodiments, components common to embodiments already described will be omitted from description and will be denoted by the same reference numerals. Figure 4 is a perspective view showing the suspension member 10 and the displacement suppression member 11 in the suspension section 21.

[0057] In the first embodiment, the displacement suppression member 11 is provided only at one end of the suspension member 10 in the longitudinal direction, whereas in the second embodiment, the suspension portion 21 and the displacement suppression member 11 are provided at both ends of the suspension member 10 in the longitudinal direction. Therefore, at one end in the longitudinal direction, the end face 19 of the displacement suppression member 11 can abut against the side surface of the locking piece 13 of the clip 9 in the opposite direction to that of the other end. Consequently, displacement of the suspension member 10 is suppressed in both directions in the extending direction of the suspension groove 8. Other effects are the same as in the first embodiment.

[0058] A third embodiment will be described with reference to Figure 5. Figure 5 is a perspective view showing the suspension member 32 and the displacement suppression member 33 in the suspension section 31. The suspension section 31 according to the third embodiment differs from the first embodiment in that the suspension member 32 and the displacement suppression member 33 are separate components.

[0059] The displacement suppression member 33 is made of the same material as the suspension member 32. The material for creating the suspension member 32 and the displacement suppression member 33 is created by the same method as the method for creating the suspension member 10 (see Figure 3) described in the first embodiment. Therefore, this material includes the skin connecting portion 16 and the bulging portion 17. The length of this material is set to be longer than the sum of the longitudinal lengths of the suspension member 32 and the displacement suppression member 33. The suspension member 32 and the displacement suppression member 33 are created by cutting this material with a plane perpendicular to the extending direction.

[0060] Since the material of the displacement suppression member 33 is the same as the material of the suspension member 32, the effort required to manufacture the displacement suppression member 33 is reduced. Furthermore, the third embodiment has the same effects and advantages as the first embodiment, except for the notch portion 18 (see Figure 3). Also, similar to the second embodiment, the displacement suppression member 33 may be attached not only to one end in the longitudinal direction of the suspension member 32, but to both ends. Furthermore, the displacement suppression member 33 may be provided not only at a position that abuts against the clip 9 provided at the end in the extending direction, but also at a position that abuts against the clip 9 provided in the middle part in the extending direction. In the illustrated example, the displacement suppression member 33 is provided only on one side in the extending direction for one clip 9, but it may be provided on both sides. A single displacement suppression member 33 placed between two clips 9 may be able to abut against the corresponding clips 9 at both end faces 19 in the extending direction.

[0061] The fourth embodiment will be described with reference to Figures 6 to 9. Figure 6 is a perspective view showing the suspension member 42 and the displacement suppression member 43 in the suspension section 41, Figure 7 is an exploded view showing the displacement suppression member 43, Figure 8 is a cross-sectional view showing the attachment of the suspension member 42 to the clip 9, and Figure 9 is a partial cross-sectional side view showing the attachment of the suspension member 42 to the clip 9. The fourth embodiment differs from the third embodiment in the suspension member 42 and the displacement suppression member 43.

[0062] As shown in Figure 9, the suspension member 42 is similar to the suspension member 32 of the third embodiment (see Figure 5) in that it has a surface connecting portion 16 and a bulging portion 17, but differs in that a notch 44 is provided in the bent portion 8a where the bottom surface of the suspension groove 8 bends. The notch 44 is provided from the side of the bulging portion 17, dividing the bulging portion 17 and cutting out the surface connecting portion 16 in a concave shape. The suspension member 42 includes a plate 45 provided on the seating surface side of the notch 44. The plate 45 is fixed to one side of the surface connecting portion 16 by sewing. Both ends of the plate 45 in the extending direction are located outward in the extending direction from both ends of the notch 44 in the extending direction. In the portion where the bottom surface of the suspension groove 8 is inclined with respect to the horizontal plane, it is preferable that the end of the plate 45 overlaps with the end of the displacement suppressing member 43 in the extending direction when viewed from the depth direction of the suspension groove 8. The bending rigidity of the plate 45 is preferably higher than that of the skin connecting portion 16. For example, the plate 45 is made of a sewable resin.

[0063] As shown in Figures 6 to 9, the displacement suppression member 43 is a flexible sheet-like member and has an opening 46 that penetrates in the thickness direction. When the displacement suppression member 43 is unfolded, the opening 46 is rectangular, and it is preferable that the outer shape of the displacement suppression member 43 is also rectangular with sides parallel to the sides of the opening 46. The displacement suppression member 43 has a predetermined thickness, and an end face 47 is formed on the inner circumference of the displacement suppression member 43 that defines the opening 46. It is preferable that the displacement suppression member 43 has a thickness greater than the surface connecting portion 16, and for example, felt is used as the material.

[0064] The displacement suppression member 43 is attached to the bulging portion 17 and the outer surface connecting portion 16 of the suspension member 32 by overlapping them from both sides in the width direction (the front and back direction of the outer surface connecting portion 16) so that the portion of the bulging portion 17 of the suspension member 32 that engages with the locking claw 15 is exposed by the opening 46, and the portion of the bulging portion 17 adjacent to the portion exposed by the opening 46 is surrounded by the member, and the member is fixed to the outer surface connecting portion 16 by sewing. As a result, the end faces 47 of the displacement suppression member 43 that face each other in the extending direction face the side surface of the locking piece 13 of the clip 9 in the extending direction, and even a slight displacement of the suspension member 32 in the extending direction causes the end faces 47 to come into contact with the locking piece 13. In its original position, one or both of the end faces 47 may be in contact with the locking piece 13.

[0065] The creation of the notch 44, the attachment of the plate 45 to the suspension member 42, and the attachment of the displacement suppression member 43 to the suspension member 42 are performed after the displacement suppression member 43 is attached to the surface material 6 in order to facilitate their position adjustment. However, these operations may also be performed before the displacement suppression member 43 is attached to the surface material 6 in order to improve work efficiency.

[0066] By providing the notch 44, it becomes easier to deform the suspension member 42 to match the shape of the suspension groove 8.

[0067] In order to compensate for the decrease in bending rigidity of the suspension member 42 caused by the division of the bulging portion 17 by the notch 44, the plate 45 suppresses the displacement of the two bulging portions 17, which are opposite each other with respect to the notch 44, toward each other.

[0068] Since the end face 47 defining the opening 46 of the displacement suppression member 43 can come into contact with the locking piece 13 of the clip 9, displacement of the suspension member 42 in the extending direction is suppressed. The displacement suppression member 43 can be applied to both the clip 9 provided at the end in the extending direction and the clip 9 provided in the middle.

[0069] The fifth embodiment will be described with reference to Figure 10. Figure 10 is a partial cross-sectional side view of the suspension portion 51. The fifth embodiment differs from the fourth embodiment in that, unlike the fourth embodiment where the suspension member 42 has a notch 44 (see Figure 9), the fifth embodiment has a slit 53 instead of a notch 44.

[0070] The slit 53 is provided by cutting the suspension member 52 from the bulging portion 17 at a position corresponding to the bent portion 8a. The slit 53 divides the bulging portion 17 and reaches the vicinity of the portion attached to the plate 45 in the skin connecting portion 16. The fifth embodiment has the same effects as the fourth embodiment.

[0071] The sixth embodiment will be described with reference to Figure 11. Figure 11 is a partial cross-sectional side view of the suspension portion 61. The sixth embodiment differs from the fourth embodiment in that, while the notch 44 of the suspension member 42 in the fourth embodiment is provided from the bottom side of the suspension groove 8 (see Figure 9), the notch 63 of the suspension member 62 is provided from the side edge that is connected to the surface material 6 in the surface connecting portion 16, and the plate 45 (see Figure 9) is not provided.

[0072] The notch 63 cuts out the skin connecting portion 16 from the side edge that connects to the skin material 6 in the skin connecting portion 16 at a position corresponding to the bent portion 8a, up to the bulging portion 17. By providing the notch 63, it becomes easier to deform the suspension member 52 to match the shape of the suspension groove 8. Unlike the fourth embodiment, since there is a bulging portion 17 with higher bending rigidity than the skin connecting portion 16 at a position corresponding to the bent portion 8a, the displacement of the portions of the bulging portion 17 that engage with the two adjacent clips 9 on either side of the notch 63 is suppressed.

[0073] 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. The present invention can be applied not only to vehicle seats but also to seats for other vehicles, as long as the seat includes a pad and a surface material. [Explanation of Symbols]
