Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to an automobile seat (seat).
More specifically, the present invention relates to a trim cover in which a decorative groove is provided on a body in a vertical direction, and a terminal and a town on the body are sewn in a horizontal direction.

[0002]

2. Description of the Related Art An automobile seat shown in FIG. 4 has a body (1) in a trim cover constituting a surface of a seat cushion (SC) and a seat back (SB) and has a deep depth in the longitudinal direction (front-back direction). By providing many decorative grooves (a),
The appearance quality of the sheet has been improved. The terminal in the vertical direction of the body (1) in the trim cover is sewn to the town (2) in the horizontal direction.

[0003]

By the way, the linear decorative groove (a) provided on the body (1) of the trim cover is arranged in one direction on the side of the town (2) as shown in FIG. Due to the curvature, there was a problem that the appearance quality of the sheet was impaired. This body (1) has a skin (11),
It consists of a laminate of a foam wadding (12) and a backing fabric (13) and covers a molded foam cushion (3). In FIG. 5, (1a) (1a)
(1a) shows a curved portion of the decorative groove (a).

The body (1) of the above trim cover is shown in FIG.
As shown in (1), waddings (12) consisting of a large number of blocks (urethane foam slab material) are arranged in parallel on a backing base cloth (13) at predetermined intervals, and between each wadding (12). A deep groove is formed, and each wadding (12) (12)... Is covered with a skin (11), and a part of the skin (11) is bitten into the deep groove of each wadding (12). The skin (11) of the bitten portion is sewn to the backing fabric (13). The seam allowances (11a), (11b), and (13a) for the town (2) are provided at the ends of the skin (11) and the backing fabric (13).
(11b) shows the seam allowance of the skin (11) in the decorative groove (a).

FIG. 7 shows a state in which the body (1) is sewn to the town (2), and the skin (1) in the body (1) is sewn.
The seam allowances (11a) and (11b) of 1) are crushed in one direction by the pressing of the sewing machine, and are sewn to one side to the town (2). Therefore, the vicinity of the seam allowances (11a) and (11b) for the town (2) of the body (1) is bent in one direction and sewn, and as shown in FIG.
A curved portion (1a) that impairs the appearance of the sheet is formed on the side of the straight decorative concave groove (a). In FIG. 7, (15) indicates a sewing thread in which the skin (11) and the backing fabric (13) are sewn in the deep grooves of the waddings (12) (12). Accordingly, the present invention provides a trim cover for an automobile seat formed by sewing a gusset in a lateral direction on a body in which such linear decorative grooves are provided in parallel in the vertical direction. An object of the present invention is to prevent the decorative groove on the gusset side from being deformed in a curved shape.

[0006]

In order to achieve the above object, according to the present invention, the outer skin located at the end of the decorative groove is substantially diamond-shaped by opening the opening on the center line of the decorative groove. It is characterized by being folded into a shape and sewn to the town.

[0007] Since the terminal of the decorative groove on the skin is folded in an approximately rhombic shape on the extension of the decorative groove and sewn around, the decorative groove is formed linearly to the end.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a state in which a town (2) is sewn to the body (1). The town (2) is turned over and overlaps the body (1), and the seam allowance (21) of the town (2) is a sewing thread (14). The sewing is sewn to the sewing allowance of the body (1). As shown in FIG. 6, the body (1) has a large number of block bodies (urethane foam slab material) waddings (12)... To cover the skin (11) and wadding (12) ...
The wadding (12) ... the skin (11) and the backing base cloth (13) that have been bitten between are sewn together to form a decorative groove (a). Use the formed one.

Further, the seam allowances (11a) and (11a) of the skin forming the end of the decorative groove (a) in FIG.
b) is folded into a substantially rhombic shape as shown in FIGS. 2 and 3 so that the opening (112) in the folded portion is positioned on the center line in the width direction of the decorative groove (a). . In the figures, (111), (111)... Indicate rhombic folded portions of the skin (11) forming the ends of the decorative grooves (a). Town (2)
Seam allowance.

The outer skin forming the end of the above-described decorative groove (a) is subjected to knob sewing to obtain the outer skin shown in FIGS.
As shown in FIG. 7, a rhombus-shaped folded portion (111) is formed.

As shown in FIG. 1, the seam allowance (21) of the town (2) is sewing-stitched integrally with the seam allowance of the body (1) in the horizontal direction. As shown in FIG. 5, the cushion body (3) is covered. Then, the decorative groove (a) is linearly formed up to the end on the side of the town (2), and as shown in FIGS. 4 and 5, the end of the decorative groove (a) has a curved portion (1a). ... does not occur.

[0012]

[Effects of the Invention] The present invention is constructed as described above, so that when the town is sewn laterally to the epidermis having a vertically extending decorative groove on the surface, the town side of the decorative groove is curved. No deformation occurs. Therefore, if the decorative concave groove is linear, the decorative concave groove is linear to the gusset side, and the appearance quality of the sheet can be improved compared to the conventional product.
