Description

[Detailed Description of the Invention] <<Technical Field of the Invention>> This invention relates to an automobile seat, and more specifically, to an improvement in the structure of a seat in which a frame is housed inside a pad material.

<<Prior Art and Its Problems>> Conventionally, seats for passenger cars have been used in which a frame body made of a wire material such as metal is housed inside a pad material. This inner wire material is called an inner wire, and after the inner wire is set, it is formed by integrally foaming a urethane solution, or a sheet pad is formed by laminating and molding a flat pad material on the wire material. Ru.

FIG. 1 is a perspective view showing an example of a frame used in the conventional sheet as described above, and the frame 1 is formed from a wire material such as metal into a substantially U-shape. This frame 1 is housed inside a cushion pad material 2, as shown in FIG. 2, and serves as the core material of the pad material.

FIG. 3 shows a cross section of the side portion (line A--A) of the cushion pad shown in FIG. 2; FIG. 3a shows the case of a urethane pad, and FIG. 3b shows the case of a palm pad. The urethane pad shown in Figure 3a is made by setting the frame 1 in a foaming mold and foaming a foamable synthetic resin solution (urethane) in the mold to integrally mold the frame 1 and the pad material 2a. be. In addition, in the palm pad shown in FIG. 3b, the frame 1 is made of a flat synthetic resin pad material (palm material) 2b
The pad material 2b is then laminated and bonded to form a pad.

In the conventional structure in which the frame 1 is fixed inside the pad material as described above, the wire of the frame 1 and the pad material 2a
Alternatively, since the fixing (integral molding or adhesion) with 2b is done only on the surface of the wire, the adhesion force between the two is insufficient and there is a limit to the resistance of the wire to coming off when a load is applied. For this reason, the pad material often cracks and breaks due to the load.

≪Purpose of the invention≫ In view of the above-mentioned conventional problems, the purpose of this invention is to provide a sheet having a pad that increases the pull-out resistance of the frame wire material and does not cause damage to the pad material. This was done as a.

≪Structure of the invention≫ The seat of the present invention is a seat in which a frame made of a wire rod such as a metal is housed inside a pad material as described above, and a plurality of fabric-like small pieces are arranged in the frame in such a manner that one end thereof is alternately oriented. It is characterized in that the other end is covered with an upper pad material attached with a gap therebetween. For this pad material covering, either the urethane pad or the palm pad described in the prior art example can be applied.

<<Embodiments of the invention>> The configuration of the invention will be described in detail below based on the embodiments shown in the drawings.

4 and 5 are perspective views showing one embodiment of the seat pad according to the present invention. FIG. 4 shows the state of the frame before being fitted into the pad material, and FIG. 5 shows the frame. The cushion pad is shown with the interior made of padded material.

The frame 1 used in the present invention is formed by molding a metal wire rod into the required shape (approximately U-shaped in the illustrated example) as in the conventional example described above, but in the present invention, the frame body 1 is shaped like the one shown in FIG. As can be seen, a plurality of fabric-like small piece members 4 are attached at intervals. This fabric-like small piece member 4 is made by cutting natural fiber cloth or synthetic fiber cloth such as cheesecloth or canvas into any desired shape and size, such as a rectangle, and wrapping one end of the cloth around the frame 1 and gluing, clipping or fixing. It is fixed with sutures. As the material of the fabric-like small piece member 4, any natural fiber cloth or synthetic fiber as mentioned above may be used, but it is preferable to use a material that is soft and has high strength.

Figure 6 shows a cross section of the side part of the pad in Figure 5 (line B-B in Figure 5), Figure 6a shows the case of the urethane pad, and Figure 6b shows the case of the palm pad. . In the case of the urethane pad shown in FIG. 6a, the fabric-like small piece member 4 is integrally molded together with the frame 1 within a pad material 2a of foamable synthetic resin (urethane). In this case, it is preferable to use a fabric-like small piece member 4 that has good adhesiveness to urethane.
In addition, it is preferable that the texture is somewhat coarse (for example, mesh-like) so that the urethane stock solution can pass through during foam molding. In the case of the palm pad shown in FIG. 6b, the fabric-like small piece member 4 is sandwiched between laminated synthetic resin pad materials (palm materials) 2b and fixed by adhesive or the like.

In this way, the fabric-like small piece member 4, which is housed inside the pad material 2a or 2b together with the frame 1, increases the fixing area between the frame 1 and the pad material 2a or 2b, and reduces the pull-out resistance of the frame 1. This has the effect of greatly improving performance.

<<Effects of the invention>> As is clear from the above explanation, the pad for a seat of the present invention is provided by attaching the woven small piece member 4 that expands the fixing area to the frame body inside the pad material, and then forming the pad by foam molding or lamination. Since the pad is formed by adhesion or the like, resistance to coming off when a load is applied is increased, and cracking and damage to the pad material can be prevented. Regarding this pull-out resistance, according to this example, the pull-out resistance of the conventional structure without the fabric-like small piece member was 5 kg, but as a result of implementing the present invention, a pull-out resistance of 10 kg was obtained. . In addition, compared to the conventional method in which a cloth-like material is stretched over the entire frame line, the method has better workability and is very advantageous in terms of cost. Moreover, since this small piece member is made of a soft material, the seat occupant will not feel a foreign body sensation. Moreover, the molding process can be performed using a conventional mold as is, without particularly modifying the mold.
