2. Description of the Related Art Conventionally, as shown in FIGS.
As shown in (c), FIG. 5 and FIG. 6, respectively, a seat cushion 1 of a vehicle seat has a seat frame 2 made of a wire frame and the like and a pad material 3 which are integrally molded, and the surface of the pad material 3 is a skin material 5. Is formed by being coated with.

As shown in FIGS. 4B and 4C, the skin material 5
A hook member 7 made of synthetic resin is attached to the end 5a of the hook member, and the hook 7a on the end side of the hook member 7 is inserted into the recess 3a formed on the back surface side of the pad material 3 and positioned in the recess 3a. It is locked to the seat frame 2 formed of a wire frame or the like, or the locking portion 4 formed on the seat frame 2 side.

Further, as shown in FIGS. 5 and 6, a soft resin core material 8 is attached to the end portion 5a of the skin material 5 of the seat cushion 1 by bag stitching, and the core material 8 is composed of a wire frame. It is locked to the side by an ohm clip 9 or the like. In this case, a low-priced material such as a non-woven fabric 5b is sewn to the end portion 5a of the skin material 5, and the core material 8 is attached to the non-woven fabric 5b by bag stitching.

However, in the conventional structure for attaching the skin material of the vehicle seat, the engaging work for engaging with the hook member or the like is complicated, and a small change in the seat shape, for example, the pad material 3 is required. When the size, thickness, bending of the hook member 7, and the like were changed to some extent, the ability to follow these small changes was poor.

In the case of the constructions shown in FIGS. 5 and 6, respectively, the locking work by the ohm clip 9 is complicated, and the end portion 5a of the skin material 5 is pulled by the ohm clip 9, and the lateral gusset of the skin material 5 is pulled. There is a risk that wrinkles 5c may be generated on the parts and the like, and the appearance may be deteriorated. Furthermore, when disassembling the seat cushion, it is necessary to remove each of the ohmic clips 9 one by one. It was something that could not be done.

Further, when the seat frame 2 and the pad material 3 are integrally molded, the pad material 3b formed by integral foaming is adhered to the seat frame 2 in the recess 3a formed on the back surface side of the pad material 3. It becomes difficult to lock the hook 7a of the hook member 7 to the seat frame 2 or the locking portion 4 formed on the seat frame 2 side, and automation work by a machine is difficult.
The longer the length L is, the longer the length of the pad material 3b is broken, which is difficult.

An object of the present invention is to easily and quickly perform a hooking operation using a hook member, to easily and quickly sew an end portion of a skin material and a hook member, and to change a length of a base end side of the hook member. In addition, it is possible to have a degree of freedom, it is easy to perform human work and automation work, seat assembly work can be done easily and quickly, wrinkles do not occur, and the appearance appearance can be improved. (EN) Provided is a structure for mounting a skin material for a vehicle seat, which is capable of performing a seat dismantling work simply and quickly.
