Description

[Technical field]

[0001] The present invention relates to a suspender and a seat trim. [Background technology]

[0002] The following Patent Document 1 discloses a suspender having a cover hanging member and a reinforcing piece fixed to the end of the cover hanging member. In the portion of the cover hanging member described in this document where the reinforcing piece is fixed, a number of slits (triangular holes) are formed along the reinforcing piece. By adopting this configuration, the occurrence of wrinkles in the skin member is prevented. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-196043 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the configuration described in the above Patent Document 1 does not take into consideration preventing or suppressing the formation of wrinkles in the covering material when the covering material is joined to the suspenders in a curved state.

[0005] In consideration of the above-mentioned facts, the present invention aims to solve the problem of preventing or suppressing the formation of wrinkles in a covering material when the covering material is joined to the suspenders in a curved state. [Means for solving the problem]

[0006] The suspenders of the first embodiment comprise a belt-shaped hanging member, a reinforcing piece fixed to one end of the hanging member in the short side direction, and a notch formed at the end of the other short side of the hanging member, the other short side of the hanging member being openable and the one short side being closed, the open end portion narrowing before the hanging member is bent to one short side, and the open end portion widening when the hanging member is bent to one short side.

[0007] According to the first aspect of the suspenders, when the hanging member is bent toward one side in the short side direction, the open end of the notch formed at the end of the hanging member on the other side in the short side direction widens. With this configuration, when the hanging member is bent toward one side in the short side direction, the hanging member is prevented from deforming in a wavy manner. As a result, even if the covering material is joined to the hanging member in a state where the hanging member is bent toward one side in the short side direction, the occurrence of wrinkles in the covering material can be prevented.

[0008] The seat trim of the second embodiment includes the suspenders of the first embodiment, a first cover material covering a portion of the seat pad and joined to the hanging member, and a second cover material covering another portion of the seat pad and joined to the hanging member.

[0009] The seat trim of the second aspect includes the suspender of the first aspect, so that even if the first and second skins are joined to the hanging member in a state in which the hanging member is curved toward one side in the short direction, the occurrence of wrinkles in the first and second skins can be suppressed.

[0010] The seat trim of the third embodiment is the seat trim of the second embodiment, further comprising a first sewing member that extends along the longitudinal direction of the hanging member and passes through a portion on the open end side of the cutout to join the first upholstery material to the hanging member, and a second sewing member that extends along the longitudinal direction of the hanging member and passes through a portion on the closed end side of the cutout relative to the first sewing member to join the first upholstery material and the second upholstery material to the hanging member.

[0011] According to the seat trim of the third aspect, the first upholstery material can be joined to the hanging member via the first sewing member (the first upholstery material can be tack-stitched to the hanging member). Next, the first upholstery material and the second upholstery material can be joined to the hanging member via the second sewing member (the first upholstery material and the second upholstery material can be sewn to the hanging member). Incidentally, when the hanging member is bent to one side in the short direction, the change in the dimension of the cutout is greater on the open end side than on the closed end side. Here, in the seat trim of the third aspect, the second sewing member for sewing the first upholstery material and the second upholstery material to the hanging member passes through a portion of the cutout on the closed end side than the first sewing member. This makes it possible to suppress the occurrence of wrinkles in the first upholstery material and the second upholstery material when they are sewn to the suspenders. Effect of the Invention

[0012] The suspenders and seat trim according to the present invention have the excellent effect of preventing or suppressing the formation of wrinkles in an upholstery material when the upholstery material is joined to the suspenders in a curved state. [Brief description of the drawings]

[0014] A suspender 10 and a seat trim 12 according to an embodiment of the present invention will be described with reference to Figs. 1 to 5.

[0015] Fig. 1 shows suspenders 10 that are attached (hanging) to a seat pad 28 (see Fig. 5) described below. As shown in this figure, suspenders 10 include a belt-shaped hanging member 14 and a reinforcing piece 16 fixed to hanging member 14.

[0016] The hanging member 14 is formed in a long strip shape. Here, one side in the longitudinal direction of the hanging member 14 is indicated by an arrow A1, and one side in the lateral direction of the hanging member 14 is indicated by an arrow A2. The longitudinal direction and lateral direction of the hanging member 14 coincide with the longitudinal direction and lateral direction of the suspenders 10, respectively. A reinforcing piece 16 formed in a line or rod shape is fixed to an end portion on one lateral side of the hanging member 14. This reinforcing piece 16 reinforces the end portion on one lateral side of the hanging member 14 along the longitudinal direction.

[0017] A notch 18 is formed at the end portion on the other side in the short side direction of the hanging member 14. In the example shown in Fig. 1, two notches 18 are formed at the end portion on the other side in the short side direction of the hanging member 14, but the number of notches 18 is not limited to this. The number of notches 18 may be appropriately set in consideration of the configuration of the skin material to be joined to the hanging member 14.

[0018] The shape of the notch 18 when viewed from the thickness direction of the hanging member 14 before bending the hanging member 14 in the short side direction is formed into a shape in which the other short side of the hanging member 14 is open and one short side is closed. Specifically, the notch 18 has a U-shaped curved portion 18A on the closed end side and a narrowed portion 18B on the open end side, forming a teardrop shape. The shape of the notch 18 is not limited to this shape.

[0019] As shown in Figs. 2 to 4, a first covering material 20 and a second covering material 22 are joined to the suspenders 10 described above.

[0020] 2 shows the first covering material 20 to be joined to the suspenders 10. As shown in this figure, the end 20A of the first covering material 20 on the side to be joined to the suspenders 10 is gently curved.

[0021] As shown in Fig. 3, first, the first covering material 20 is temporarily sewn to the suspenders 10. More specifically, the suspenders 10 (hanging members 14 and reinforcing pieces 16) are curved toward one side in the short direction, so that the suspenders 10 are placed along the end 20A of the first covering material 20 and the two are overlapped. At this time, the portion 18B on the open end side of the cutout portion 18 is expanded.

[0022] Next, the first covering material 20 is temporarily sewn (joined) to the hanging member 14 by sewing along the longitudinal direction of the hanging member 14 and passing through the portion 18B on the open end side of the notch 18. The sewing thread used to temporarily sew the first covering material 20 to the suspenders 10 is called the first sewing member 24. In this embodiment, before the suspenders 10 are bent to one side in the short side direction, the portion 18B on the open end side of the notch 18 is narrowed relative to the portion 18A on the closed end side. Therefore, compared to a configuration in which the portion 18B on the open end side of the notch 18 is not narrowed relative to the portion 18A on the closed end side, the expansion of the portion 18B on the open end side of the notch 18 when the suspenders 10 are bent to one side in the short side direction is suppressed. This makes it possible to suppress the temporary sewing in this process from becoming difficult.

[0023] 4, the first and second upholstery materials 20 and 22 are then stitched to the hanging member 14. More specifically, the end 20A of the first upholstery material 20 and the end 22A of the second upholstery material 22, which have been temporarily sewn to the suspenders 10, are overlapped. The end 22A of the second upholstery material 22 is also gently curved into a shape corresponding to the end 20A of the first upholstery material 20.

[0024] Next, the first and second skins 20 and 22 are stitched (joined) to the hanging member 14 by sewing along the longitudinal direction of the hanging member 14 and passing through a portion 18A closer to the closed end of the cutout 18 than the first sewing member 24. The sewing thread used to stitch the second skin 22 to the suspenders 10 is referred to as the second sewing member 26.

[0025] Through the above steps, the first cover material 20 and the second cover material 22 are joined to the suspenders 10, and the seat trim 12 is formed.

[0026] 5, the seat trim 12 described above is attached to the seat pad 28 with the suspenders 10 hung in grooves 28A formed in the seat pad 28. The reinforcing pieces 16 of the suspenders 10 are engaged with insert wires embedded in the seat pad 28 via hog rings. When the seat trim 12 is attached to the seat pad 28, a portion 28B of the seat pad 28 is covered with the first cover material 20, and another portion 28C of the seat pad 28 is covered with the second cover material 22.

[0027] As described above, in the suspenders 10 of this embodiment, when the hanging member 14 is bent toward one side in the short side direction, the portion 18B on the open end side of the notch 18 widens. In this configuration, when the hanging member 14 is bent toward one side in the short side direction, the portions on both sides of the notch 18 in the hanging member 14 are prevented from deforming so as to shrink in the short side direction of the hanging member 14. In other words, the hanging member 14 is prevented from deforming in a wavy manner. As a result, even if the first covering material 20 and the second covering material 22 are joined to the hanging member 14 in a state in which the hanging member 14 is bent toward one side in the short side direction, it is possible to prevent wrinkles from occurring in the first covering material 20 and the second covering material 22.

[0028] 4 and 5, the first and second upholstery materials 20 and 22 are fixed to the seat pad 28 in a state in which the first and second upholstery materials 20 and 22 are turned inside out relative to the state in which the lock stitching is completed. In addition, the change in dimension of the cutout portion 18 when the hanging member 14 is bent toward one side in the short direction is greater at the open end side than at the closed end side. Therefore, by orienting the open end side of the cutout portion 18, which has a greater change in dimension, toward the opposite side to the first and second upholstery materials 20 and 22, it is possible to suppress the occurrence of wrinkles in the first and second upholstery materials 20 and 22 when the first and second upholstery materials 20 and 22 are turned inside out relative to the state in which the lock stitching is completed.

[0029] In the above-described example, the first and second upholstery materials 20 and 22 are joined to the suspenders 10 using the first and second sewing members 24 and 26, but the present invention is not limited to this. For example, the first and second upholstery materials 20 and 22 may be joined to the suspenders 10 using only a sewing member corresponding to the second sewing member 26.

[0030] Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement the present invention in various other modified forms without departing from the spirit and scope of the present invention.
