Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting an assembly part of an instrument panel.

[0002]

2. Description of the Related Art Generally, a steering device 5 such as a steering wheel 51 and a steering column 52 is provided inside an instrument panel of an automobile as shown in FIG.
A steering support member 54 that supports 3 is arranged along the vehicle width direction. This support member 54
Is coupled to the floor tunnel 57 near the center of the vehicle body through a pair of braces 55 and 56, thereby suppressing the vibration of the steering device 53.
In addition, the radio which is installed in the instrument panel,
Various assembling parts such as an ashtray and a glove box are fastened and fixed to the braces 55 and 56, the instrument panel main body and the like with bolts and nuts.

[0003]

However, in the above-mentioned support structure for the assembled parts, the assembled parts in the central part of the instrument panel such as a radio and an ashtray and the glove box which is the other assembled parts are not provided. Since it is configured to be fixed to different members, it is difficult to improve the accuracy and rigidity of the entire instrument panel, and there is a problem that vibration of the instrument panel cannot be suppressed. The center portion of the vehicle body of the support member 54 is connected to the floor tunnel 57 via braces 55 and 56, but other members are not connected between the center portion of the vehicle body and the end portion on the passenger seat side. In addition, the rigidity of the entire support member 54 is insufficient, so that the vibration of the steering device 53 cannot be sufficiently suppressed.

The present invention has been made in view of the above circumstances, and an object thereof is to increase the rigidity of the entire instrument panel and the steering support member and suppress the vibration of the instrument panel and the steering device. An object of the present invention is to provide a support structure for assembling an instrument panel that can be assembled.

[0005]

In order to solve the problems of the above-mentioned prior art, in the present invention, a steering support member is provided inside the instrument panel along the vehicle width direction, and below the support member. There
A lower member is arranged in front of the passenger seat side, the lower member and the support member are connected by a brace, and the assembly member of the instrument panel is fastened and fixed to the lower member.

[0006]

[Operation] In the instrument panel assembly component support structure according to the present invention, the steering support member and the lower member, which are provided along the vehicle width direction, are joined by braces, and the instrument panel assembly component is attached to the lower member. Since the instrument panel is fixed by tightening, the radio, ashtray, etc. of the central part of the instrument panel and the glove box, etc. located on the passenger side can be attached to the same member, which increases the accuracy of the entire instrument panel. The rigidity of the instrument panel and steering support member is improved. Further, since the lower member is arranged below the steering support member and in front of the passenger side, when the impact energy is applied from the front of the vehicle body, the knee of the passenger on the passenger side is placed inside the instrument panel. It is possible to reduce the amount of movement toward the side.
