Embodiment approach 2

[0063] like figure 1 , FIG. 6 and FIG. 7 , this embodiment is an example in which the sewn structure 1 is applied to the surface material 721 of the seat back 72 in the automobile seat (front seat 70). In addition, descriptions of the same configurations and effects as those in Embodiment 1 are omitted.

[0064] like Figure 6A , Figure 6B As shown, in the surface material 721 of the seat back 72 , four cloth-like surface sheets are sewn to each other, and there is a concave (concave-shaped) stitched confluence portion 722 formed by joining the four surface sheets at one point. The stitched junction 722 has a stitched structure 1 . in addition, Figure 6A will be figure 1The figure which enlarges and shows the B part of the seat back 72.

[0065] For example, referring to FIG. 2 , the sewn structure 1 has two first skin sheets 10A, 10B having the same structure as the first skin sheet 10 of the first embodiment described above and the second skin sheet 20 of the first e...

Embodiment approach 3

[0079] like Figure 8 ~ Figure 1 1, this embodiment is an example in which the sewn structure 1 is applied to the skin material of another automobile seat (rear seat 80). In addition, descriptions of the same configurations and effects as those in Embodiment 1 are omitted.

[0080] like Figure 8 As shown, the rear seat 80 for an automobile includes a seat cushion (not shown), a seat back 82 , a headrest (not shown), and the like on the left and right sides, respectively. In the rear seat 80 , an armrest accommodating recess 84 for accommodating an armrest (not shown) is provided between the seat backs 82 on the left and right sides. The bottom surface and the inner wall surface of the handrail housing recess 84 are formed of a skin material 841 .

[0081] like Figure 9A , Figure 9B As shown, in the skin material 841 of the handrail receiving recess 84, three cloth-like skin sheets (the first skin sheet 10, the second skin sheet 20, and the third skin sheet 30) are sewn...

Abstract

The invention provides a sewing structure capable of suppressing the generation of wrinkles at a sewing confluent part resultant from a sewing margin, and improving industrial design properties. A sewing structure 1 comprises a first skin piece (first sewing object material) 10, a second skin piece (second sewing object material) 20, and a third skin piece (third sewing object material) 30. The first skin piece 10 has a first A sewing margin 11, a first B sewing margin 12, and a first lap part 13. The second skin piece 20 has a second A sewing margin 21, a second B sewing margin 22, and a second lap part 23. The third skin piece 30 has a third A sewing margin 31. A first sewing part 51 where the first skin piece 10 and the second skin piece 20 are sewn with each other keeps one end 511 extending to the position of a second sewing part 52 where the first skin piece 10 and the second skin piece 20 are sewn with the third skin piece 30 and not present at the first lap part 13 of the first skin piece 10 and at the second lap part 23 of the second skin piece 20.

Description

technical field [0001] The present invention relates to a sewn structure and a surface material of a vehicle seat provided with the sewn structure. Background technique [0002] Conventionally, for example, the skin material of a vehicle seat is constructed by sewing a plurality of cloth-like skin sheets (see JP 2015-000202 ). The skin material has a structure in which three or more skin sheets are sewn together, and these skin sheets meet at one point. The stitched confluence portion is formed in a slightly depressed concave shape or the like in accordance with the shape of the vehicle seat or the like. [0003] For example, in the case of forming a suture confluence portion by three skin sheets (the first skin sheet, the second skin sheet, and the third skin sheet), at first, one end edge portion forming a corner of the first skin sheet and the second skin sheet One edge portions forming the corner portions of the skin sheets are sewn together with seams provided. Next,...
