Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garnish mounting structure for an armrest in a vehicle seat, and more specifically,
The present invention relates to a mounting structure for an armrest having a mounting body which is mounted on a support shaft of a seat back in a vertically rotatable manner and which is covered with a garnish.

[0002]

2. Description of the Related Art A mounting body is attached to a support shaft protruding from a seat back so as to be rotatable in the vertical direction, and an armrest body is attached to the mounting body. It can be rotatably attached.

Therefore, since the armrest main body is mounted by the mounting body so as to be rotatable in the up-down direction and the left-right direction, it is possible to mount the armrest main body which is excellent in supportability of the elbow of the seated person and has a wide width in the left-right direction. In addition, the width of the armrest body in the left-right direction can be adjusted by rotating the armrest body in the left-right direction.

Since the mounting body is exposed to the outside, it needs to be covered with a resin garnish.

[0005]

By the way, as described above, the mounting body is pivotally attached to the support shaft of the seat back in a vertically rotatable manner. Therefore, since the top surface and the bottom surface of the mounting body are exposed to the outside due to the rotation of the mounting body, it is necessary to cover the entire surface of the mounting body with the garnish.

Further, since the mounting body is movable, it is necessary to fix the garnish so that the garnish is not detached from the mounting body.

Therefore, an object of the present invention is to make it possible to easily and surely attach the garnish to the attachment body.

[0008]

According to the present invention for achieving the above object, the garnish is composed of a pair of upper and lower containers, each of which has a convex portion and a concave portion which are engaged with each other at the opening edge thereof. At the same time, the inner surface of each container is provided with a projection to be inserted into the through hole provided in the mounting body, and a fixing piece is integrally molded in one of the housings, and the fixing piece is provided in the fixing hole provided in the mounting body. It is characterized by being fixed with a clip.

With the above construction, each container is positioned on the mounting body by inserting the projection of each container into the through hole of the mounting body, and the fixing piece provided on one of the containers is fixed to the mounting body with a clip. Thus, one container is fixed to the mounting body, and the other container is engaged with the convex portion and the concave portion that engage with the one container, whereby they are integrally coupled and may be detached from the mounting body. Cover the attachment so that there is no leakage.

Further, by providing a reinforcing rib on the inner surface side of each of the containers, the tip edge portion of which is in contact with the outer surface of the mounting body, the garnish is detached from the mounting body even when an external impact is applied to the garnish. Never.
