Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resin seat back board used for a vehicle seat.

[0002]

[Background technology]

 In a vehicle, such as an automobile, when the front seat is finished with a resin seat back board, the resin seat back board fits on the back seat occupant's back, so multiple back seats are used. Since the structure in which the reinforcing ribs are integrally formed to increase the rigidity has been adopted, the waist of the rear seat occupant may hit the seat back board and hurt.

[0003]

[Challenges for devising]

 An object of this invention is to provide a resin seat back board that relieves pain when a rear seat occupant is seated.

[0004]

[Means corresponding to the problem and action thereof]

 In this invention, the bending structure is provided on the back surface of the lower waist contact portion of the seat back board body to facilitate bending of the lower portion of the seat back board body.

[0005]

[Explanation of specific examples]

 Hereinafter, the resin seat back board of the present invention will be described based on the specified and illustrated specific examples. FIG. 1 shows the resin seat back board of the present invention applied to a front side seat of a passenger car. A specific example 10 of the seat back board made of resin is shown. In this resin seat back board 10, a flexible structure 19 is applied to the back surface 14 of the lower waist contact portion 13 of the body 11 of the seat back board.

The flexure structure 19 is provided by omitting the reinforcing rib from the back surface 14 of the lower waist contact portion 13 to facilitate flexure.

Further, in the resin seat back board 10, 15 is a reinforcing lateral rib, 16 is a reinforcing vertical rib, 17 is a hook, and 18 is a screw hole boss.

The resin seat back board 10 has an upper side when the seat back board body 11 is molded from resin in a mold (not shown). The back side 14 of the portion 12 is integrally formed with the reinforcing lateral ribs 15, the reinforcing vertical ribs 16 and the hooks 17, and the lower waist contact portion 13 of the seat back board body 11 is formed. The back surface 14 was provided with the flexible structure 19. Of course, the threaded hole boss 18 is formed in the lower waist contact portion 13.

The resin seat back board 10 manufactured in such a structure was used by being assembled to the seat back of the front side seat, but the waist of the occupant of the rear seat was Upon hitting, the lower waist contact portion 13 of the resin seat back board 10 was easily bent and the occupant was relieved of pain.

Particularly, in the flexible structure 19, the reinforcing ribs are omitted from the back surface 14 of the lower waist contact portion 13. In addition to omitting the reinforcing ribs, the thickness of the lower waist contact portion 13 is reduced. It is possible to make it thinner to make it more flexible.

FIG. 2 shows another specific example 20 of the resin seat back board of the present invention applied to the front side seats of the passenger car, in which the resin seat back board 20 is bent. The structure 21 is applied to the back surface 14 of the lower back rest portion 13 of the seat back board body 11.

In addition to omitting the reinforcing ribs from the back surface 14 of the lower waist contact portion 13, the flexible structure 21 has three vertical grooves 22 at predetermined intervals on the back surface 14 of the lower waist contact portion 13. It is just opened. As a result, the lower waist contact portion 13 of the seat back board body 11 was very easily bent.

As is apparent from the embodiments of the present invention described with reference to the drawings, the contents of the present invention can be understood by those having ordinary skill in the art of the present invention. , Is derived from the technical essence of the device, which is essential to the formation of the device and is the nature of the device in order to accomplish the task of the device, and is objectively recognized to be inherent in it. Embodiments are easily embodied.

[0014]

[Benefits of the device]

 As can be understood from the above, in the resin seat back board of the present invention, since the flexible structure is applied to the back surface of the lower waist contact portion of the seat back board body, the occupant of the rear seat does not feel The lower part of the body of the seat back board is easily flexed during application to reduce the pain to the occupant and give the appearance a normal finish, which is very useful for the vehicle seat. It is practical.
