Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle seat, and more particularly to an assembly structure for assembling a rear seat cushion of an automobile seat to a vehicle floor.

(Prior art) Conventionally, in order to assemble a rear seat cushion (rear seat seat) to the vehicle floor, the common method was to fix the completed rear seat cushion to the vehicle floor from the outside with screws. The cushion is provided with a bracket for fixing it to the vehicle floor, and this bracket is fixed to the vehicle floor with screws. Therefore, according to this fixing method, the fixing members such as brackets and screws are visible from the outside, resulting in a problem that the aesthetic appearance is impaired.
Therefore, methods for eliminating such problems have been disclosed in Japanese Utility Model Application Publication No. 55-129844, Japanese Utility Model Application Publication No. 56-36530, and the like. These do not have the above-mentioned problems because they are assembled without using any screws that are visible from the outside, but they do have the drawback of complicating the structure because protrusions such as holders must be provided on the vehicle floor.

(Purpose) Therefore, the object of the present invention is to improve the workability by having a simple structure and easy installation on the vehicle floor.

(Structure) Therefore, in the present invention, the seat (rear seat cushion) that is attached to the vehicle floor is formed by separately forming the cushion body covered with the skin and the frame, and then attaching the frame to the vehicle floor by a method such as screwing. After being fixed to the frame, the hook of the cushion body is engaged with a lock spring provided on the frame. In order to securely fix the cushion body to the frame, the hook of the cushion body is inserted into a long hole of a bracket provided in the frame. Therefore, the screws that fix the frame are covered by the cushion body and cannot be seen from the outside, and since only the frame is attached to the vehicle floor, all that is needed is to provide mounting holes in the vehicle floor.
There is no need to protrude protrusions like in the conventional product,
Installation work becomes simple and easy.

(Example) Next, an example of the present invention will be described based on the drawings.

Fig. 1 shows the rear seat cushion A assembled on the vehicle floor 7, with a frame c fixed by screws 6, 6, etc., and a foam cushion body a with a skin b attached to the frame c. ing. B in the figure indicates the rear seat back.

The frame c is made by bending and welding pipes as shown in FIG. 4B, and nuts 5, 5 for fixing the frame to the vehicle floor 7 with screws 6 are fixed at appropriate locations. As shown in FIG. 5, locking members for locking the cushion body a are provided on the front left and right sides of the frame c. That is, a bracket 2 with a long hole 21 is welded together, and a shaft 31 is installed at the bottom of the bracket 2, and a lock spring 3 made of a torsion coil spring is wound around the bracket 2. This lock spring 3 is biased so that its central protrusion 3a is inserted into the hook 1 which is inserted into the elongated hole 21 and protrudes downward.

On the other hand, the cushion body a is made of molded urethane foam and has a large number of wires d shown in FIG. 4A.
A wire structure d consisting of wires 1 and d1 is integrally provided at the bottom, and a hook 1 is integrally provided downward at a position of the wire structure d corresponding to the elongated hole 21 of the bracket 2 of the wires d1 and d1. is welded to. This hook 1 is formed by bending a wire into a U-shape as shown in FIG. Can be installed without any problem. When the lock spring 3 engages with the portion projecting downward from the elongated hole 21, vertical movement of the cushion body a with respect to the frame c is restricted.

The end of the skin b covering the cushion body a is fixed to the outer periphery of the wire structure d with a hogging ring or the like.

The rear part of the cushion body a is connected to the rear part of the frame c by a clip 4 via a wire structure d, and the wire structure d is attached to the cushion body a.
It may be housed in the mold and integrally molded during foam molding, but it is also optional to assemble it to the cushion body a by binding the ends of the skin b as described above after foaming the cushion body a. be.

Thus, as shown in FIG.
is fixed to the vehicle floor 7 with screws 6, etc., and then the cushion body a covered with the skin b is connected to the rear part of the frame c with the clip 4 at its rear part, and then the front part of the cushion body a is placed on the frame c. When placed,
The hook 3 on the cushion body a side is inserted into the elongated hole 21 in the bracket 2 on the frame c side and protrudes downward against the elasticity of the lock spring 3. At the same time, the protruding portion of the lock spring 3 is inserted into the protruding hook 3. A portion of the hook 3a engages within the hook c, resulting in a locked state. Therefore, as mentioned above,
The cushion body a is securely fixed to the frame c,
Movement of the cushion body a in the front and back, left and right, and up and down directions is restricted.

(Effect) According to the present invention, on the frame fixed to the vehicle floor,
Since the structure is such that the cushion body with a skin is fixed, the part where the seat is fixed to the car floor is hidden by the cushion body, so the fixing member is not visible from the outside compared to the conventional products that are fastened with screws, etc. Looks good when assembled.
Furthermore, since the frame can be fixed to the vehicle floor with screws or the like, the structure and assembly are easier than in the conventional product in which the holder is provided upright and protruding from the vehicle floor. Furthermore, the cushion body is attached to the frame by inserting the hook provided on the cushion body side into a long hole in the bracket of the frame and engaging with the lock spring provided below the bracket.
The cushion body is securely attached to the frame and does not move back and forth, left and right, or up and down during use. Furthermore, by operating the lock spring, the cushion body can be easily and conveniently removed from the frame.
