Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch base mounting structure typically provided in a door trim of a side door in a vehicle such as a passenger car.

[0002]

2. Description of the Related Art In a vehicle of this kind, a door switch for opening and closing a side window is usually arranged at a predetermined portion of a door trim inside a side door. This door switch is equipped by fitting and fixing a switch base on which a plurality of switches are mounted in a receiving opening set at a predetermined part of the door trim.

For example, as shown in FIGS. 8 and 9, a receiving opening 102 (FIG. 8) is provided on the upper surface of an armrest set at a predetermined portion of a door trim 101 inside a side door. As shown in FIG. 9, a switch base 103 unitized with a plurality of switches mounted thereon is attached to the opening 102. Door trim 101, opening 102 or switch base 103
Etc. are usually made of synthetic resin, and are formed by a molding die using a synthetic resin material.

An armrest portion is usually arranged on the rear side of the door switch, and the armrest is provided so as to project to a predetermined position of the door trim 101 so that an arm or an elbow can be placed. In FIG. 8, the arrow F in the three-axis direction indicates the front, the arrow U indicates the upper direction, and the arrow W indicates the vehicle width direction.

In the switch base mounting structure of this example, since the width W1 of the upper surface of the armrest is set to be a predetermined width or more, the dimensions of the opening 102 and the door trim 101, and the dimensions of the opening 102 and the armrest R portion. Since the shelf width W2 is sufficiently secured, it is possible to secure the rigidity around the opening and also to secure the high rigidity even after the switch base 103 is attached.

[0006]

On the other hand, as shown in FIG. 10, there is one in which the switch base 103 (and therefore the opening 102) is formed including the ridge line L due to the design relationship of the armrest. In this case, as shown in the figure, the switch base 103 or the opening portion 102 is extended not only to the upper surface of the armrest but also to the region of the side surface portion on the front side, and the cross section 103a of the switch base 103 (hatched portion).
Is formed in an approximate "ku" shape or a "shi" shape. It is not easy to secure the rigidity of the armrest with the opening 102 including the ridge line L as it is.
For example, when an elbow is placed on the armrest portion and weight is applied, the opening 102 is deformed, causing a so-called mouth opening, which causes the claw to come off.

In view of the above points, the present invention provides a switch base mounting structure capable of reliably and appropriately increasing the rigidity of the opening, preventing deformation, and expanding the degree of freedom in design. The purpose is to

[0008]
