Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface material attachment body for a vehicle seat, and particularly to one for attaching the end or center side of the surface material to a cushioning material side.

Generally, a vehicle seat is composed of a cushioning material 2 such as foamed urethane held by a frame 1 and a surface material 3 covering the cushioning material 2, as shown in FIG. A mounting body 5 is connected to the 4 side by sewing. The mounting body 5 is in the form of a band, and is composed of a plate material 6 made of synthetic resin as shown in FIG. As shown, a bag part 9 is formed by folding the tip end of the cloth material 8 inward and sewing it, and a wire 10 is inserted through the bag part 9. The body 5 is attached by attracting the distal end thereof to, for example, a hole 12 provided in the frame 1. As a result, the surface layer material 3 is pulled toward its end, so that it covers the cushioning material 2 while maintaining a tensioned state.

However, according to the mounting body having such a configuration, when a part of the distal end 5a side of the mounting body 5 is attached to the frame 1 by drawing it to the frame 1 side with the clip 11 as shown in FIG. 4, the distal end 5a is flexible. Therefore, it does not have much rigidity, so clip 1
The portion 15 pulled by the clip 1 is deformed in the pulling direction of the clip 11, and the portions 16, 16 on the opposite side of the mounting body 5 corresponding to this deformed portion 15 are
Since a large pulling force is concentrated at these parts 16, 16, the pulling force at these parts 16, 16 becomes large, and a large depression is formed in the surface layer material 3, resulting in an unsightly appearance.

The purpose of this invention is to form a rigid part consisting of a large diameter part that bulges out in the front and back directions and extends along the longitudinal direction in the middle of a belt-shaped mounting body made of a plate made of synthetic resin, so that the tip side of the mounting body has an ohm shape. This method eliminates the above drawback by uniformly applying the pulling force exerted by the clip on the opposite side of the mounting body, and will be explained in detail below using examples.

FIG. 5 is a perspective view showing an embodiment of the vehicle seat surface material attachment body according to the present invention. In the figure, 20 is a frame for holding a cushioning material 21 made of urethane foam, and this frame 20 A plurality of springs 22 that hold the buffer material 21 are installed in a bridging manner, and a slit 23 is provided in the buffer material 21 at a location corresponding to, for example, one spring 22. A mounting body 25 whose one end is connected to the back surface on the center side of the surface material 24 covering the cushioning material 21 is inserted. Furthermore, one end of a mounting body 26 for attaching this terminal to the frame 20 side is attached to the terminal side of the surface material 24 by sewing. These mounting bodies 25, 26
As shown in Fig. 6, synthetic resin is formed into a thin band shape by extrusion molding, and a rigid part that expands in the front and back direction is inserted between the surface material side and the clip side. A large diameter portion 29 extending along the lengthwise direction is integrated along the lengthwise direction.

According to this configuration, the clips 11, 11 are provided on the distal ends of the mounting plates 25, 26, and with the clips 11, 11 tensioned, the mounting body 25 is attached to the frame 20, and the mounting body 26 is attached to the spring 22. By attaching it to the cushioning material 21 side, the surface layer material 24 can be attached to the cushioning material 21 side. In this case, the mounting body 2
When the pulling force of the ohm clip 11 is applied to the ohm clips 5 and 26, the ohm clip 11 side is deformed from the large diameter part 19, and the pulling force is applied to the large diameter part 29. Since it extends along the direction, the pulling force is distributed over the entire large diameter portion 29, and therefore the large diameter portion 2
9 to the surface layer material 24 side, the pulling force is transmitted uniformly, and the pulling force is no longer concentratedly applied to the surface layer material 24, so that local dents occur on the surface side of the surface layer material 24 as in the conventional case. I won't.

In addition, in the present invention, the wire rod 30 may be integrated into the large diameter portion 29 as shown in FIG.

As explained above, according to the surface material attachment body for a vehicle seat according to the present invention, a rigid portion consisting of a large diameter portion that bulges in the front and back directions and extends along the longitudinal direction is provided between the surface material side and the clip side. This prevents the pulling force of the clip from being applied intensively to the surface material, suppressing the occurrence of local dents on the surface side of the surface material, and allowing the surface material to be installed accurately. Therefore, a high-quality vehicle seat can be obtained.
