BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat, and more particularly to a seat in which an armrest is provided on the seat back.

[0002]

2. Description of the Related Art For example, Japanese Utility Model Laid-Open No. 6-190 discloses an example in which a stopper member for holding an armrest arranged in a seat back of a conventional seat is held.

[0003]

However, in such a conventional technique, since the stopper member is provided at the upper end of the armrest in the retracted state, the stopper member is exposed when the armrest is in use. And it doesn't look good. Further, since the stopper member is a member different from the seat back and the armrest, it causes a cost increase.

The present invention has been made in view of such a conventional technique, and provides a seat in which the cost can be reduced and the appearance of the armrest in the used state is improved.

[0005]

According to a first aspect of the present invention, a skin of a seat back made of a material that can be folded back is provided with a recess in which an armrest can be retracted.
The upper end of the armrest can be locked by the stopper portion formed by folding back the skin of the upper edge of the recess.

According to the first aspect of the present invention, even if the armrest receives the load from the rear side to the front side by the stopper portion at the upper edge of the concave portion only by storing the armrest in the concave portion of the seat back. It is possible to prevent the armrest from jumping out to the front side or falling to the front side. Since the stopper portion is formed integrally with the outer skin, the cost is reduced, and the stopper portion is difficult to see unless the concave portion is looked into, so that the appearance of the armrest in use is improved.

According to a second aspect of the present invention, a seat back is formed by covering a built-in object with a skin made of a material that can be folded back, and a recess is formed on the front side of the skin, and a lower position of the seat back. Between the seat cushion and the substantially vertical position stored in the recess and the substantially horizontal position projecting from the seat back along the seat cushion so as to be rotatable about the lower side. In the seat configured at least with the armrest, the stopper is formed on the upper edge of the recess by folding back the skin so that the upper end of the armrest can be locked.

According to the second aspect of the present invention, the stopper is formed by folding back the outer skin of the upper edge of the recess made of the same material as the outer skin simply by storing the armrest in the recess of the seat back. Therefore, even if the armrest receives a load from the rear side to the front side, it is possible to prevent the armrest from jumping out to the front side or falling down to the front side, and since the stopper part is formed integrally with the outer skin, the cost is reduced. Reduce. Since the stopper portion is formed on the upper edge portion of the concave portion, the stopper portion is difficult to see unless the concave portion is looked into, and the appearance of the armrest in the used state is improved.

According to a third aspect of the present invention, in the seat according to the second aspect, the stopper portion is formed by folding back a front surface of a skin forming an upper wall of the recess so as to double the front side. It is formed by projecting inward.

According to the invention of claim 3, claim 2
In addition to the above effect, since the stopper portion is formed by double-folding the outer skin forming the upper wall of the recess of the seat back, the cost is low because it is not a separate member. Further, since the stopper portion projects the outer skin to the inside of the recess, it cannot be seen at the upper end portion of the armrest, and the appearance of the armrest is improved.
