Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engaging member and a mounting structure for a skin material forming a vehicle seat.

[0002]

2. Description of the Related Art Conventionally, a seat seat installed in an automobile is sewn to a flexible pad material by sewing attachment members having engaging pieces at both ends of a skin material and sewn to one end side thereof. The hook portion formed on the one mounting member is engaged with the locking portion provided on the pad material, and the locking piece formed on the one mounting member is sewn to the other end side. The one in which the locking pieces formed on the other mounting member are hooked and locked to each other is used.

[0003]

However, the locking structure on the opposite side to engage with the receiving portion having the hook piece attached to one end of the skin material in the conventional vehicle seat has a structure in which the skin material is ∪ A flat plate-like fastening piece is provided as a core material in the middle folded back in a V shape, and a hook-like locking member is provided on the side opposite to the fastening piece through the end of the skin material to provide the fastening piece / skin material. / The hook-shaped locking members are made by aligning the upper ends of three sheets and also by stitching four sheets together with the skin material at the lower end of the back surface of the backrest. In that case, since the upper ends of the plate-shaped fastening piece, the end of the skin material, and the hook-shaped locking member are aligned and sewn together, the first problem is that the ends of the three members are Alignment is time-consuming, secondly, even if the edges are aligned, a displacement is inevitable, and thirdly, the skin material at the ends of the flat plate-like fastening piece and the hook-like locking member is easily cut off, In addition, since the fastening piece and the locking member are separate members, it is necessary to separately mold and process the two pieces, so that there are four problems that the manufacturing cost becomes high.

[0004]

According to the present invention, in order to solve the above-mentioned problems, the flat plate-like fastening piece and the locking member with a hook piece described in claim 2 are flexible and easy to bend. Extruded continuously in the shape of a river through the joint,
It can be cut to make an integrally molded product with hook pieces.

Specifically, the flat plate-shaped fastening piece and the hooked locking member are made of polypropylene that is moderately flexible and strong, and the band-shaped joint that connects both is easily bent.
It is made of a soft elastomer having rubber elasticity, and the desired molded product can be made by integrally molding two different materials with a two-color molding machine and cutting.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of a structure for mounting a skin material on a vehicle seat according to the present invention will be described below with reference to the accompanying drawings. 1 is a schematic view of a backrest portion of a vehicle seat as viewed from the front, and FIG. 2 is a schematic view of the backrest portion as viewed from the rear, showing a state before engagement of a locking member according to the present invention, FIG. 3 is a cross-sectional perspective view of a lower end of a conventional backrest portion, and FIG. 4 is a schematic view of a locking member of a skin material according to the present invention.
FIG. 5 is a sectional perspective view showing an engaging structure of the locking member.

Conventionally, as shown in FIG. 3, a back portion of a vehicle seat installed in an automobile has a skin material 1 on the surface of a flexible pad material such as urethane foam 2.
a and 1b are covered, a receiving portion 3 having a hook piece is sewn on the peripheral end of the skin material 1a, and on the opposite side, the skin material 1b is folded back in a ∪ shape to form a flat plate with a core material. Fastening piece 5
And a hook-like locking member 4 is provided on the side opposite to the fastening piece 5 through the end of the skin material, and four pieces of skin material / fastening piece / skin material / hook-like locking member are provided. It is made by stitching together.

According to the present invention, the fixing piece 6C in the form of a flat plate and the locking member 6a in the form of a hook are integrally molded and cut through the flexible band-shaped joining material 6b to cut the fixing piece and the hook-shaped engagement member. This can be achieved by joining the stopper members and creating a new locking member 6 in which the band-shaped joint portion in the middle is bent. That is, instead of the conventional locking member 4 and the fastening piece 5 of FIG. 3, the new locking member 6 is bent as shown in FIG. 5, and the other bent skin material 1b is engaged and attached. The hook portion 6a of the locking member is engaged with the receiving portion 3 attached to the end portion of the skin material 1.

[0009]

According to the present invention, the locking member 6 described in claim 2 is bent in a ∩ shape around the easy-to-bend joint 6b, and the skin material 1b is sewn by engaging the end bent in a ∪ shape in the inner surface direction. Then, since the end portion of the skin material 1b is wound in a ∩ shape by the new locking member 6, positioning of the fastening piece 6C / skin material 1b / hook-shaped locking member 6a is easy. The edges will not slip and the skin will not be scratched. Further, since the locking member is a one-piece molded product, the cost for manufacturing the molded product can be reduced as compared with the conventional two-piece molded product.
