Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat, and more particularly to a seat back cover mounting structure for a vehicle seat having a backboard on the back surface of the seat back.

[0002]

BACKGROUND OF THE INVENTION In a front seat of a vehicle such as a passenger car, a backboard may be set as one structure of a back portion of a seat back due to performance improvement or design requirements.

FIG. 3 shows a schematic structure of a front seat having a backboard on the back surface of the seatback.
The seat 10 includes a seat cushion 11 and a seat back 1.
A headrest 13 is attached to the upper part of the seat back 12. A backboard 14 is arranged at the center of the back surface of the seatback 12.

The seat back 12 is, as shown in FIG.
It is provided with a pad portion 15 as a cushion material, a frame 16 forming a skeleton, a seat back cover 17 forming an outer skin, and the above-mentioned back board 14. The seat back cover 17 wraps around the pad portion 15 and wraps around from the lower side to the rear side, and its terminal is fixed to the frame 16 together with the back board 14 on the rear side of the seat back 12. In that case, for example, a hanging bag 18 containing an edge wire is sewn to the end of the seat back cover 17, and the hanging bag 18 is fixed to the frame 16.

The backboard 14 is preferably made of a synthetic resin material, etc.
It is fixed at 6. A plug fall 20 is attached to the fastening position of the screw 19 from above to hide the screw 19. Further, an extension portion 14a is provided at the lower end of the backboard 14 so as to cover the hanging bag 18 and the like together with the terminal of the seat back cover 17.

[0006]

However, in the conventional seat back 12, the screw 19 portion is covered by the plug fall 20 on the rear side of the seat back 12, or the extension 14a is provided on the back board 14 so that the seat back cover 17 is covered. In order to secure the appearance, such as covering the terminals and the hanging bag 18, the structure has to be complicated. In addition, it takes time and effort to assemble each member, and the number of parts must be increased.

In view of the above points, an object of the present invention is to provide a seat back cover mounting structure for an automobile seat, which can easily and appropriately improve the appearance.

[0008]

A structure for mounting a seat back cover of a vehicle seat according to the present invention is a vehicle seat having a backboard on the back surface of the seatback, wherein the lower end portion of the backboard hangs over the seatback cover. The present invention is characterized in that a stop portion is provided, and the end of the seat back cover is hooked on this hook portion.

In the seat back cover mounting structure for a vehicle seat according to the present invention, the hooking portion is formed in a substantially U-shape, and is arranged at substantially the same height behind the fastening position of the back board to the seat back frame. It is characterized by being done.

In the seat back cover mounting structure for an automobile seat according to the present invention, the seat back cover is attached so as to wrap around from below the hooking portion of the backboard, and its end is a U-shape of the hooking portion. It is characterized in that it is inserted into the inner recess.

In the seat back cover mounting structure for an automobile seat of the present invention, a core material is attached to an end of the seat back cover, and the core material is hooked to the hook portion.

According to the present invention, a hook portion for the seat back cover is provided at the lower end portion of the backboard. The hooking portion is formed in a substantially U shape, and is arranged corresponding to the fastening position of the backboard to the seatback frame. Therefore, the seat back cover can be attached so as to wrap around from below the hooking portion, and the end thereof can be easily fixed by being inserted into the U-shaped inner recess of the hooking portion. By attaching the seat back cover in this manner, it is possible to obtain a very good appearance and appearance.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a seat back cover mounting structure for an automobile seat according to the present invention will be described below with reference to the drawings, in which members substantially the same as or corresponding to those in the conventional example are designated by the same reference numerals. Will be explained. 1 and 2 show
1 shows a configuration of a main part of a seat back cover mounting structure in an embodiment of the present invention. In this embodiment, the present invention is typically applied to a front seat (or a second seat) of a vehicle such as a passenger car.

Also in this embodiment, as described above, the sheet 1 is used.
0 is composed of a seat cushion 11 and a seat back 12, and a headrest 13 may be attached to the upper part of the seat back 12. The backboard 1 is arranged in the center of the back surface of the seatback 12.

The basic structure of the seat back 12 is substantially the same as that of the conventional example, and is composed of a pad portion 15 as a cushion material, a frame 16 forming a skeleton, and a seat back cover 17 forming a skin. (See FIG. 2).

In the present invention, as shown in FIG. 1 in particular, a hook 2 for the seat back cover 17 is provided at the lower end of the backboard 1, and the seat back cover 17 is provided.
The terminal of the seat back cover 17 is hooked on this hooking portion 2 by covering the whole hooking portion 2 from the outside with this terminal. As shown in FIG. 2, the hooking portion 2 is formed in a substantially U shape or as a hook, and has a shape that is crenellated to the outside (rear side). Backboard 1
Is fastened and fixed to the frame 16 by the screw 19, but the hooking portion 2 is arranged at a substantially same height position behind the fastening position of the backboard 1 by the screw 19. In this case, in order to allow the screw 19 to be inserted when fixing the backboard 1, the hook 2 is provided with a notch 2a.

A strip-shaped core member 3 is attached to the end of the seat back cover 17 along the width direction. Then, the end of the seat back cover 17 is inserted into the U-shaped inner recessed portion 2b of the hooking portion 2 so as to cover the outside of the hooking portion 2 and is hooked at the portion of the core material 3. There is.
Therefore, the thickness of the end of the seat back cover 17 including the core material 3 is preferably the same as or slightly thinner than the inner width of the U-shaped inner recess 2b in the hook 2.

In the above construction, when the constituent members of the seat back 12 are assembled, the back board 1 is screwed into the screw 1.
It is fastened and fixed to the frame 16 by 9. After mounting the backboard 1, the seat back cover 17 is attached so as to wrap around from below the hook 2 as shown by the arrow in FIG. The terminal to which the core material 3 is attached is the U of the hook portion 2.
It is inserted into the character-shaped inner recess 2b.

As described above, the seat back cover 17 is
It is attached so as to wrap around from below the hanging portion 2, and its end is inserted into the U-shaped inner concave portion of the hanging portion 2 so as to be fixed easily and accurately. By attaching the seat back cover 17 in this manner, it is possible to cover all of the inner hooking portion 2, the screw 19, etc., and obtain a very good appearance.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to the embodiment, and various changes and the like can be made within the scope of the present invention. For example, the specific shape and the like of the hooking portion 2 may be a slit-shaped one in addition to the U-shaped one in the illustrated example.

[0021]

As described above, according to the present invention, a good appearance can be obtained with an extremely simple structure. In that case, there is no need to use a conventional plug fall, etc., and because it is configured with a small number of parts, it has the advantages that the product cost can be substantially reduced and the product weight can be reduced. ing.
