Description

[Technical Field]

[0001] The present disclosure relates to a hanging structure and an assembly method for a seat that includes a pad and a cover material that covers the pad and is provided with a hanging portion. [Background technology]

[0002] In seats such as vehicle seats that have a pad and a cover material covering the pad, a linear recessed portion is sometimes provided on the seating surface of the seat cushion and seat back to maintain the external shape. The cover material is hung into this hanging portion and fixed to an engaging member fixed to the pad.

[0003] The hanging groove may have a curved or bent portion that is laterally curved or bent when viewed from the front side of the seat. Various ideas have been devised to adapt a hanging structure to a hanging groove with a curved portion. Patent Document 1 describes a hanging structure including a bag-shaped hanging cloth connected to the hanging edge of the upholstery material and a string inserted into the hanging cloth and fixed in the hanging groove, in which a notch is provided in the hanging cloth at the portion that passes through the curved portion of the hanging groove. By providing a notch in the bag-shaped hanging cloth at a position corresponding to the curved portion, the difference in length between the inside and outside of the bag-shaped hanging cloth is adjusted, preventing wrinkles from forming in the hanging cloth. Patent Document 2 also describes a hanging structure including a clip fixed to the bottom of the hanging groove of the pad and a hanging member including a first edge portion connected to the hanging edge of the upholstery material by sewing and a second edge portion that engages with the clip, in which a slit is provided in the first edge portion. The slits allow the hanging member to bend to accommodate the curved portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 62-066600 [Patent Document 2] Japanese Utility Model Application Publication No. 2-092800 Summary of the Invention [Problem to be solved by the invention]

[0005] In the hanging structure described in Patent Document 1, the string is not fixed to the hanging cloth, so during assembly of the hanging structure, the hanging cloth may slide relative to the string in the longitudinal direction (extension direction) of the hanging groove, and the hanging edge of the covering material may be attached out of position. Also, in the hanging structure described in Patent Document 2, the need to provide a slit reduces work efficiency, and the second edge is rigid enough to engage with a clip, making it difficult to bend, making it difficult to connect the hanging member in a bent state to the hanging edge of the covering material by sewing or the like.

[0006] In view of these problems, the present invention aims to provide a hanging structure and an assembly method thereof in which the relative positions of components in a hanging structure having a curved portion are stable and the hanging edge of the skin material can be attached to the hanging groove in the correct position. Also, one embodiment of the present invention aims to provide an assembly method for a hanging structure using a hanging member that is resistant to bending deformation, which allows the hanging member to be easily connected to the hanging edge of the skin material in a bent state. [Means for solving the problem]

[0007] In one embodiment of the present invention, a hanging structure (10) for a seat (1) includes a pad (5) having a hanging groove (11) extending along the surface to include a curved portion (9) that is bent or curved, and a hanging edge (12) extending along the longitudinal direction of the hanging groove (11) within a section of the hanging groove (11) that includes the curved portion (9), and includes a skin material (6) that covers the surface of the pad (5), a loop member (13) connected to the hanging edge (12), and a loop member (14) that is connected to the hanging groove (11) at the bottom of the hanging groove (11). The device comprises an engaging member (14) fixed to the pad (5), and a hanging member (15) that is inserted into the loop member (13, 30) and engages with the engaging member (14) to lock the hanging edge portion (12) to the engaging member (14), the hanging member (15) including a cloth-like first edge portion (19) and a second edge portion (20) that engages with the engaging member (14) and has higher bending rigidity than the first edge portion (14), and the first edge portion (14) is connected to the loop member (13, 30).

[0008] With this configuration, the loop member is connected to the hanging edge portion and the hanging member is connected to the loop member, so the position of the hanging member relative to the loop member and the hanging edge portion is stable and the hanging edge portion can be attached to the correct position in the hanging groove.

[0009] One embodiment of the present invention is characterized in that, in the above configuration, the loop member (13) includes a bag-shaped cloth extending in the longitudinal direction and having a cutout portion (21) through which the second edge portion (20) and / or the engaging member (14) is inserted.

[0010] According to this configuration, the engaging member engages with the second edge portion directly without the fabric of the loop member being interposed therebetween, and therefore the loop member does not impair the mutual engagement between the engaging member and the second edge portion.

[0011] One embodiment of the present invention is characterized in that, in the above configuration, the cutout portion (21) is positioned and sized so as to expose the portion where the engaging member (14) engages with the second edge portion (20).

[0012] According to this configuration, the fabric of the loop member does not hinder the operation of engaging the second edge portion with the engaging member, and even if the loop member is used, workability is not impaired.

[0013] In one embodiment of the present invention, the first edge (19) is connected to the loop member (13) by sewing so as to be continuous along the longitudinal direction.

[0014] According to this configuration, the first edge portion and the loop member are firmly connected to each other by the continuous stitching.

[0015] In one embodiment of the present invention, in the above configuration, the sewing line (22) connecting the first edge (19) to the loop member (13) crosses the notch.

[0016] According to this configuration, the stitching line crosses the notch, making it easy to check the state in which the first edge portion and the loop member are connected to each other.

[0017] In one embodiment of the present invention, instead of the above configuration, the sewing line connecting the first edge portion to the loop member is provided on the edge of the cutout portion on the upholstery material side or slightly on the upholstery material side thereof.

[0018] According to this configuration, the first edge portion and the loop member are sewn together continuously, so that the first edge portion and the loop member are firmly joined to each other.

[0019] One embodiment of the present invention is characterized in that, in the above-mentioned first configuration, the loop member (30) includes a plurality of tape cloths, which are connected to the hanging edge portion (12) by sewing at intervals in the longitudinal direction to define a cutout portion (31) that exposes the second edge portion (20) from the loop member (30).

[0020] With this configuration, by aligning the cutout portion with the part with the greatest curvature or the center of the curvature in the longitudinal direction, the first edge portion and the loop member can be sewn together while avoiding that part, making the connection process easier.

[0021] In one embodiment of the present invention, in any of the above configurations, the first edge (19) has a color different from that of the loop member (13, 30).

[0022] According to this configuration, the color of the first edge exposed from the cutout portion is different from the color of the loop member, and therefore the visibility of the first edge portion is improved, improving workability.

[0023] One embodiment of the present invention is characterized in that, in any of the above configurations, the section of the hanging groove (11) includes a straight portion (8), and the hanging edge portion (12) includes a straight section (23) that is hung into the straight portion (8), and the hanging structure (10) of the seat (1) further includes a straight section hanging member (24) that engages with the engaging member (14) to lock the straight section (23) to the engaging member (14), and the straight section hanging member (24) includes a cloth-like straight section first edge portion (25) and a straight section second edge portion (26) that has rigidity that allows it to engage with the engaging member (14), and the straight section first edge portion (25) is directly connected to the straight section (23).

[0024] According to this configuration, in the straight section, the straight section hanging member is directly connected to the hanging edge portion without using a loop member, so that an increase in the number of parts can be suppressed.

[0025] One embodiment of the present invention includes a pad (5) having a hanging groove (11) extending along the surface to include a curved portion (9) that is bent or curved, a hanging edge portion (12) extending along the longitudinal direction of the hanging groove (11) within a section of the hanging groove (11) that includes the curved portion (9), and a skin material (6) that covers the surface of the pad (5), a loop member (13, 30) arranged on the hanging edge portion (12), an engagement member (14) fixed to the pad (5) at the bottom of the hanging groove (11), a cloth-like first edge portion (19), and a bending member (19) having rigidity that can be engaged with the engagement member (14) to lock the hanging edge portion (12) to the engagement member (14) and having a bending strength higher than that of the loop member (13, 30) and the first edge portion (19). A method for assembling a hanging structure (10) for a sheet (1) having a hanging member (15) including a second edge portion (20) having bending stiffness, comprising the steps of: connecting the loop member (13, 30) to the hanging edge portion (12) so that the hanging member (15) is annular around the longitudinal direction and has an opening (16) on at least one side of the longitudinal direction; inserting the hanging member (15) into the loop member (13, 30) through the opening (16) so that the second edge portion (20) is positioned on the opposite side of the hanging edge portion (12) with respect to the first edge portion (19); connecting the first edge portion (19) to the loop member (13, 30); and engaging the second edge portion (20) with the engaging member (14).

[0026] With this configuration, the loop member is connected to the hanging edge portion, and the hanging member is connected to the loop member, so the position of the hanging member relative to the loop member and the hanging edge portion is stable, and the hanging edge portion can be attached to the hanging groove in the correct position. Furthermore, because the hanging member is connected to the loop member after being connected to the hanging edge portion, the hanging member before being connected to the loop member is stable in a bent state within the loop member. This makes it easy to connect the hanging member to the loop member. [Effects of the Invention]

[0027] According to the sheet hanging structure of the present invention, the loop member is connected to the hanging edge portion and the hanging member is connected to the loop member, so the position of the hanging member relative to the loop member and the hanging edge portion is stable and the hanging edge portion can be attached to the correct position in the hanging groove.

[0028] According to one embodiment of the present invention, by providing a cutout portion, the engagement member engages with the second edge portion directly without going through the fabric of the loop member, so the loop member does not impair the mutual engagement between the engagement member and the second edge portion.

[0029] According to one embodiment of the present invention, the cutout portion is set to a size and position that does not interfere with the engagement of the fabric of the loop member with the engagement member of the second edge, so that workability is not impaired even when the loop member is used.

[0030] According to one embodiment of the present invention, the first edge and the loop member are firmly connected to each other by a continuous stitch.

[0031] According to one embodiment of the present invention, the sewing line crosses the notch, making it easy to check the connection state between the first edge portion and the loop member.

[0032] According to one embodiment of the present invention, the first edge and the loop member are sewn together continuously, so that the first edge and the loop member are firmly joined to each other.

[0033] According to one embodiment of the present invention, the loop member comprises a plurality of tape fabrics with cutouts defined therebetween, and by aligning the cutouts with the most curved portion or the center of the longitudinal curve, sewing between the first edge and the loop member can be performed while avoiding that portion, making this connection process easier.

[0034] According to one embodiment of the present invention, the color of the first edge exposed through the cutout is different from the color of the loop member, which increases the visibility of the first edge and improves workability.

[0035] According to one embodiment of the present invention, in the straight sections, the straight section hanging member is directly connected to the hanging edge portion without using a loop member, so that an increase in the number of parts can be suppressed.

[0036] According to the method for assembling a seat hanging structure of the present invention, the loop member is connected to the hanging edge portion, and the hanging member is connected to the loop member, so the position of the hanging member relative to the loop member and the hanging edge portion is stable, and the hanging edge portion can be attached to the hanging groove in the correct position. Furthermore, because the hanging member is connected to the loop member after being connected to the hanging edge portion, the hanging member before being connected to the loop member is stable in a bent state within the loop member, which makes it easier to connect the hanging member to the loop member.

[Figure 5] FIG. 10 is an explanatory diagram showing an assembly method of the hanging structure according to the embodiment. [Figure 6] FIG. 10 is a perspective view showing a loop member according to a modified example of the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0038] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a vehicle seat 1 (hereinafter referred to as "seat 1") according to an embodiment. The seat 1 includes a seat cushion 2 supported by a 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, the seat back 3, and the headrest 4 includes a pad 5 (see FIG. 2) made of a foamed resin such as urethane foam, and a cover material 6 covering the seating side of the pad 5. The seating side surfaces of the seat cushion 2 and the seat back 3 are formed with a plurality of linearly recessed hanging portions 7, 7a formed by the cover material 6 being tucked into the pad 5. The hanging portions 7a of the seat cushion 2 extend laterally at the rear, extend forward from both ends, and curve outward at their front ends. When viewed from a direction perpendicular to the seating surface, the hanging portions 7a have a linearly extending straight portion 8 and curved portions 9 that are bent or curved laterally relative to the linear portion 8. The hanging portion 7a having the curved portion 9 is provided on the seat cushion 2 in the illustrated example, but may be provided on the seat back 3.

[0039] 2 shows a hanging structure 10 for a seat 1 according to an embodiment. The hanging structure 10 comprises a pad 5 having a hanging groove 11 extending along its surface to include a bent or curved portion 9 (see FIG. 1), a hanging edge 12 extending in the longitudinal direction of the hanging groove 11 within a section of the hanging groove 11 that includes the curved portion 9 (hereinafter, unless otherwise specified, "longitudinal direction" refers to the longitudinal direction of the hanging groove 11 (the extending direction including the curved portion 9)) and covering the surface of the pad 5, a loop member 13 arranged on the hanging edge 12, an engaging member 14 fixed to the pad 5 at the bottom of the hanging groove 11, and a hanging member 15 that is inserted into the loop member 13 and engages with the engaging member 14 to lock the hanging edge 12 in the engaging member 14.

[0040] The pad 5 is made of foamed resin such as urethane foam. The hanging groove 11 opens toward the seating surface.

[0041] The hanging edge 12 of the covering material 6 is formed by abutting the ends of two covering materials 6 so that their surfaces match and connecting them by sewing, etc. Alternatively, the hanging edge 12 may be formed by folding one covering material 6 so that the surface side forms a valley and connecting the abutting parts by sewing, etc.

[0042] As shown in Figure 3, the loop member 13 is made of a bag-shaped cloth with openings 16 at both longitudinal ends. The loop member 13 is connected to the hanging edge 12 by sewing or the like along the longitudinal direction (the reference symbol "13a" indicates a sewing line). The opening 16 is set to a size that allows the hanging member 15 to be inserted into the loop member 13. Both longitudinal ends of the loop member 13 are inclined so that the distance between both longitudinal ends of the loop member 13 becomes shorter from the hanging edge 12 side toward the bottom of the hanging groove 11.

[0043] The engaging member 14 is a clip including a base plate 17 embedded in the bottom of the hanging groove 11 and a pair of locking claws 18 extending from the base plate 17 into the hanging groove 11. The engaging member 14 made of a clip is embedded in the pad 5 when the pad 5 is foamed.

[0044] As shown in FIG. 2 , the hanging member 15 includes a first edge 19 made of a cloth-like material such as a nonwoven fabric, extending in the longitudinal direction and connected to the loop member 13 by sewing or the like, and a second edge 20 made of a resin or the like, extending in the longitudinal direction and connected to the end of the first edge 19 on the hanging groove 11 side. The hanging member 15 extends linearly when no force is applied, but is bendable. The second edge 20 bulges on both sides in the thickness direction of the first edge 19 relative to the first edge 19 so as to engage with the locking claws 18 of the engaging member 14, and has sufficient rigidity to allow the locking claws 18 to engage. The second edge 20 has higher bending rigidity than the loop member 13 and the first edge 19. The second edge 20 is formed by injection molding, and the first edge 19 is connected to the second edge 20 by being attached to a mold cavity during molding of the second edge 20. When the first edge portion 19 and the second edge portion 20 are made of the same resin, the hanging member 15 may be formed by extrusion molding.

[0045] As shown in Figures 3 to 5, since the second edge portion 20 directly engages with the engaging member 14, the loop member 13 has a notch portion 21 on the side opposite to the connection portion with the hanging edge portion 12. The engaging member 14 is inserted into the notch portion 21 to engage with the second edge portion 20. Note that instead of or in addition to the engaging member 14 being inserted into the notch portion 21, the second edge portion 20 may be configured to be partially inserted into the notch portion 21. The notch portion 21 is provided at a position corresponding to the bending portion 9.

[0046] The position and size of the cutout 21 are preferably determined so as to expose the portion where the engaging member 14 engages with the second edge 20 and to expose the portion of the first edge 19 adjacent to the second edge 20. In this case, the first edge 19 preferably has a color different from that of the loop member 13. The sewing line 22 connecting the first edge 19 to the loop member 13 extends in the longitudinal direction and may cross the cutout 21 (shown by a dashed line in FIGS. 3 and 5), or may be provided at the edge of the cutout 21 on the upholstery material 6 side or slightly closer to it (shown by a two-dot chain line in FIGS. 3 and 5). The sewing line 22 may be continuous or discontinuous along the longitudinal direction.

[0047] As shown in FIG. 3 , the hanging edge portion 12 includes not only the curved portion 9 but also a straight section 23 corresponding to the straight section 8. A straight section hanging member 24 is connected to the straight section 23. The straight section hanging member 24 includes a cloth-like straight section first edge 25 and a straight section second edge 26 that engages with the engaging member 14. The straight section first edge 25 is directly connected to the straight section 23 of the hanging edge portion 12 by sewing or the like. Reference numeral 27 indicates the sewing line. The straight section second edge 26 is connected to the edge of the straight section first edge 25 on the side of the hanging groove 11. The straight section second edge 26 bulges out on both sides in the thickness direction of the straight section first edge 25 relative to the straight section first edge 25 so as to be engaged with the locking claws 18 of the engaging member 14, and has sufficient rigidity to allow the locking claws 18 to engage. The straight portion second edge 26 has higher bending rigidity than the straight portion first edge 25. The straight portion hanging member 24 may be a member having the same configuration as the hanging member 15.

[0048] 2 to 5, a method for assembling the hanging structure 10 will be described. First, as shown in FIG. 3, a worker connects the straight section hanging member 24 to the straight section 23 of the hanging edge portion 12 by sewing or the like, and then, as shown in FIG. 4, directly connects the loop member 13 to the portion of the hanging edge portion 12 corresponding to the curved portion 9 (see FIG. 3) by sewing or the like. Next, a worker inserts the hanging member 15 into the loop member 13 through the opening 16. The hanging member 15 is inserted into the loop member 13 so that the second edge portion 20 is located on the opposite side of the first edge portion 19 from the hanging edge portion 12. Next, as shown in FIG. 5, a worker connects the first edge portion 19 and the loop member 13 to each other by sewing or the like. 2 and 3, the worker inserts the hanging edge portion 12 into the hanging groove 11, engages the second edge portion 20 with the engaging member 14 of the curved portion 9, and engages the straight portion second edge portion 27 with the engaging member 14 of the straight portion 8. In the above procedure, the step of connecting the straight portion hanging member 24 to the hanging edge portion 12 may be performed at any time before engaging with the engaging member 14.

[0049] The effects of the above embodiment will be described. Because the first edge 19 is connected to the loop member 13 by sewing or the like, the hanging member 15 does not shift relative to the loop member 13 and the hanging edge 12, and the hanging edge 12 can be attached to the correct position in the hanging groove 11. In particular, if the stitching line 22 is continuous in the longitudinal direction, the hanging member 15 becomes even less likely to shift relative to the loop member 13 in the longitudinal direction.

[0050] Since the suspending member 15 is connected to the loop member 13 after the loop member 13 is connected to the hanging edge portion 12, the suspending member 15 before being connected to the loop member 13 is stable in a bent state within the loop member 13. This makes it easy to connect the suspending member 15 to the loop member.

[0051] Because the loop member 13 has the cutout portion 21, the second edge portion 20 of the hanging member 15 engages directly with the engaging member 14 via the cutout portion 21. This engagement is stronger than when engagement occurs via the fabric of the loop member 13. The position and size of the cutout portion 21 are determined so that the portion of the engaging member 14 that engages with the second edge portion 20 is exposed, making it easy to engage the second edge portion 20 with the engaging member 14 without being hindered by the fabric of the loop member 13. Because the color of the first edge portion 19 exposed from the cutout portion 21 is different from the color of the loop member 13, the visibility of the first edge portion 19 exposed from the cutout portion 21 is improved, improving workability.

[0052] When the sewing line 22 crosses the cutout portion 21, it is easy to check the connection state between the first edge portion 19 and the loop member 13. When the sewing line 22 does not cross the cutout portion 21 but passes through the edge of the cutout portion 21 or its vicinity, the connection between the first edge portion 19 and the loop member 13 becomes stronger.

[0053] In the straight section 23, the straight section hanging member 24 is directly connected to the hanging edge portion 12 without using the loop member 13, so that an increase in the number of parts can be suppressed.

[0054] A loop member 30 according to a modified example of the above embodiment will be described with reference to Fig. 6. In the description, the same components as those in the above embodiment will be denoted by the same reference numerals and description thereof will be omitted.

[0055] Two loop members 30 are connected to the hanging edge 12. Each loop member 30 includes a tape cloth. Both longitudinal ends of the tape cloth overlap and are connected to the hanging edge 12 by sewing or the like, thereby forming the loop member 30 in a loop shape and forming openings 16 on both sides in the longitudinal direction (the horizontal direction of the tape cloth). Reference numeral 30a indicates a sewing line connecting the loop member 30 to the hanging edge 12. Both longitudinal ends of each loop member 30 are inclined so that the distance between the longitudinal ends of each loop member 30 becomes shorter from the hanging edge 12 side toward the bottom of the hanging groove 11 (see Figure 2).

[0056] The two loop members 30 are arranged at a predetermined distance in the longitudinal direction, so that a notch 31 is formed between the two loop members 30 to expose the hanging member 15. The hanging member 15 is received in the loop members 30 at both longitudinal ends and is exposed from the loop member 30 at the longitudinal center.

[0057] By aligning the cutout portion 31 with the portion with the greatest curvature or the center of the longitudinal curvature, the first edge portion 19 and the loop member 30 can be connected to each other by sewing or the like while avoiding that portion, making the connecting work easier.

[0058] Although the specific embodiment has been described above, the present invention is not limited to the above embodiment and can be widely modified and implemented. The present invention can be applied not only to vehicle seats, but also to seats for other vehicles and seats placed in homes, etc., as long as the seat has a pad and a cover material.
