Description

[Detailed Description of the Invention] The present invention relates to a seat cushion for a vehicle, and particularly to a terminal structure of a skin material of a seat cushion portion.

As shown in FIG. 1, a conventional vehicle seat cushion includes a frame 1 made of resin or metal, and a spring 2 bridged inside the frame 1.
and a cushioning material 3 such as urethane foam located above the frame 1 and the spring 2;
It consists of a skin 4 covering the surface side of these cushioning materials 3. The skin 4 is formed into a bag shape by sewing the main part located on the top side of the body and the sleeve part side located on the side part, and the terminal 5 side is the bottom part of the seat cushion part S. Turn it to the side,
This terminal 5 is fixed through a hole 7 provided inside the frame 1 using an ohm clip 6 or the like. On the bottom side of this sheet S,
As a slide rail, an upper rail 27 that is slidably placed on a lower rail (not shown) is fixed, and this upper rail 27 is attached to the frame 1 via the end 5 of the skin material 4 with screws (not shown) or the like. There is.

However, according to the vehicle seat cushion configured as described above, since the upper rail 27 is fixed to the upper part of the end 5 of the skin material 4, pressure from the upper rail 27 side is applied to the end 5 side after long-term use. This has the drawback that a cut or the like occurs in the terminal 5 at the portion m where this pressure is applied, and the terminal is cut off from this portion. Also, when attaching the upper rail 27, the jig for attaching the upper rail 27 may hit the terminal 5 side and damage the terminal 5, or the screw for attaching the upper rail 27 may penetrate. A hole must be provided in the end 5, and when a pulling force is applied to the end 5, the end 5 has the disadvantage of being torn around this hole. Furthermore, it is not possible to fix the upper rail 27 to the frame 1 before attaching the skin material 4, which is a factor that reduces work efficiency.

In addition, in order to eliminate the above-mentioned drawback, the end 5 of the skin material 4 is fixed to the maximum circumferential side l of the frame 1 so that the end 5 does not extend inwardly through the space between the upper rail 27 and the frame 1. However, according to this, terminal 5
Since the clip for fixing the worm is located on the outer circumferential side l, the worm clip is visible from the outside, which is not aesthetically pleasing.

The purpose of the present invention is to fix the end of the skin material to the outer periphery of the bottom of the seat cushion and to provide a covering skin to cover this fixed part, thereby eliminating the above-mentioned drawbacks. This will be explained in detail using

FIGS. 2 and 3 are cross-sectional views showing an embodiment of the vehicle seat cushion according to the present invention.
0a, the tip side of the bent piece 10a is folded back into a cylindrical shape, and a hole 23 is provided in the upper part of this folded part 10b. A hook 11 fixed to this frame 10 has an S-shaped spring 12.
A cushioning material 13 made of urethane foam or the like is placed on top of the frame 10 and spring 12, and the entire side wall side of the cushioning material 13 and the frame 10 is covered with a skin material 14. The lower part of the skin material 14 snakes inward,
first, second and third folded portions 15 which are folded back three times;
16 and 17, and the second folded portion 16, which is a branching point, and the most distal end portion 18 are simultaneously machine-stitched 19 to the skin material 14' corresponding to the side wall of the seat cushion portion S. An end wire 21 is inserted into the hollow portion 20 obtained at the third folded portion 17, and the end wire 21 is inserted into a hole provided on the outermost side of the frame 10 by a clip 22.
It is fixed at 3.

According to the above configuration, after the end side of the skin material 14 is folded back three times, the second folded portion 16 and the leading edge portion 18 are sewn to the skin material 14 side, thereby connecting the connecting piece A and the covering skin B. By fixing the connecting piece A side to the hole 23 provided on the outer peripheral side of the frame 10 using the clip 22, the skin material 14 can be attached. Moreover, clip 2
2, since the covering skin B protrudes below the lower surface of the seat cushion part S, it is covered by this and cannot be seen from the outside, and the clip 22 is attached to the outer circumferential side of the bottom face of the seat cushion part S. It can solve aesthetic problems caused by Further, according to the present invention, since the end of the skin material 14 is not located between the upper rail 27 and the frame 10, no pressure from the upper rail is applied to the end, which prevents the end from being cut off due to long-term use. It is possible to eliminate defects such as part of the upper rail being torn when installing it. In addition, the skin material 14
Since the terminal can be attached even after the upper rail 27 is attached to the frame 10, the margin of work flow procedure can be increased, and mass production can be achieved. Also, skin material 1
Even if a connecting piece A is provided on the outer skin 14, this connecting piece A is integrated with the skin material 14, and by providing this connecting piece A, there is no problem of an increase in the number of parts, and this can be done in one sewing operation. Since the connecting piece A can be constructed, the workability of terminal processing can be simplified. In addition, since the tip of the bent piece 10a is folded back into a cylindrical shape,
This folded portion 10b can increase the mechanical strength of the bent piece 10a itself, and since the hole 23 is formed in the bent piece 10a in a vertical state,
This hole can be easily seen visually, making it easy to attach the clip 22.

In addition, in the present invention, the leading edge part 1 of the skin material 14
Although the present invention is not limited to this, only the folded portion 16 may be sewn to the skin material 14. In that case, it goes without saying that a folded sewing part for fixing the wire 21 needs to be provided on the leading edge 18 side. Furthermore, the connecting piece A may be separate from the skin material 14.

As explained above, according to the present invention, a connecting piece is branched from the inside of the end of the skin material, a wire is attached to the tip side of this connecting piece, and this wire is fixed to the outer circumferential side of the frame of the seat cushion part. Therefore, by extending the tip of the skin material below the connection piece, this part can cover the connection part made by the clip at the end of the skin material, improving the appearance and making it possible to close the skin. Damage to the end of the material can be reduced.
