Abstract

PURPOSE:To prevent a steering wheel from being pushed afterward into a cabin when a vehicle collides by configurating a device in such a way that a support member is spanned between both dash side panels and is connected with them, and the center section of the supporting member is connected to a floor side by the medium of a stay. CONSTITUTION:A support member 8A is spanned between both dash side panels 7 and is connected with them, and the center section of the support member is also connected to the upper section of a floor tunnel by the medium of a stay 6A so as to increase the stiffness of installation. On the other hand, a steel adapter plate 14 bent in a 'L' like form is arranged on the forward end of a post bracket 9A which is installed on the support member 8A, and the forward end of the post bracket 9A is connected with a dash upper panel 2 by the medium of the adapter plate 14. And a steering column 10 is installed onto the post bracket 9A in a conventional manner by the medium of a bracket 11 attached to the column 10. This configuration prevents a steering wheel 13 from being pushed afterward into a cabin when a vehicle collides.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steering column support structure for an automatic roof.

Conventional technology! Figures 3 and 4 show the conventional steering column support structure, in which the dash upper panel 2 of the cowl box 1
A stay 6 is coupled across the floor side, specifically the floor tunnel portion 5, and a support member 8t is coupled across the stay 6 and the dash side panel 7 on one side. 9 indicates a post bracket), the front end of which is connected to the dash upper panel 2, and the rear side thereof is connected to the support member 8, and the steering column lQi is attached to the steering column 10. It is attached to the post bracket 9 through the bracket 11. In the figure, 3 indicates a darts lower panel, 4 a floor panel, 12 a steering shaft, and 13 a steering handle. This similar structure is, for example,
It is shown in the publication No.-132469.

The interlocking point post bracket 9 which the invention aims to solve, and the stay 6 are rigidly connected to the dash upper panel 2. When the dash upper panel 2 is deformed and protrudes toward the iL side when both X collide, the post Bracket 9. Stay 6 Steering Column 1
There is a risk that the 0 will move backwards together with the Datsushi air bubble panel 2, causing the steering wheel 1st to protrude to the rear of the passenger compartment and narrowing the survival space in the passenger compartment.

Therefore, one of the inventions is that the dash upper panel is fixed in the event of a vehicle collision! To provide a steering column support structure capable of avoiding protrusion of a steering wheel toward the rear of a vehicle interior due to the backward movement of a post bracket, a stay, and a steering column even if the steering column is deformed and protrudes toward an L compartment side.

Ninth method to solve all the problems: Connect the support member across the dash side panels on both sides, and connect it to the floor side through the intermediate metal stay, and then attach it to this support member to support the steering column. to the post bracket that
An L-shaped mounting piece is attached from gIT direction f95, and all of the post brackets are connected to the dash upper panel.

Even if the dash upper panel protrudes toward the passenger compartment and deforms during a frontal collision of the vehicle, the support member straddles the dash side panels on both sides, and the intermediate portion is connected to the floor side by swinging the stay. Because it has been.

There is no backward movement of the support member. On the other hand, the bottom bracket attached to the support member is connected to the dash upper panel via the mounting piece at its front end.
1 for the deformation of the dash upper panel protruding toward the passenger compartment! Although it receives a pressing force toward the chamber, this pressing force is absorbed by the mounting piece being deformed from its L-shaped bent base.

Embodiments Below, one embodiment of the present invention will be described in detail with reference to the drawings, with the same parts as those of the conventional tank bottom being designated by the same reference numerals.

In FIG. 1.2, the support member 8A has dash side panels 71vlK# on both sides! and is connected to, for example, the floor tunnel portion 5 via an intermediate s5 and 6A to ensure supporting rigidity. - On the front end of the post bracket 9A attached to this support member 8A by Raku'ffk4, there is a steel plate iLL-shaped bend-formed housing piece 14t. The front end of the post bracket 9A is connected to the dash upper panel 2 via this attachment piece 14.

The steering column IO is attached to the column 10 in the same way as in the conventional case, and is attached to the post bracket 9AK via the t-bracket ll'i.

In addition to the structure of the above embodiment, even if the eight support members are installed across the dash side panels 7 on both sides, all the intermediate portions are connected to the floor tunnel section 5 by the stays 6AiC, and the rounded structure provides sufficient support rigidity. Steering shaft 12. Steering column 10. Vibrations in the steering system such as the steering wheel 13 can be completely suppressed. - In the event of a vehicle collision, even if the dash upper panel 2 protrudes toward the passenger compartment and deforms, the support member 8
A is installed across the dash side panels 7 on both sides, and 9,7746 is connected to the support member 8A across the floor tunnel section 5. Even if you answer 21, you will not receive a response session. On the other hand, the front end of the boss bracket (9A) is connected to the dash upper panel 2 by the entire mounting piece 14.

There is a tendency for a pressing force to act in the L-shape direction due to the deformation of the dash upper panel 2, but compared to the fact that the mounting piece 14 stands up in an L-shape at the front end of the post bracket 9A, the pressing force The pressure acts as a bending force on the mounting piece 14, and is absorbed by the mounting piece 14 inclining its L-shaped bent base to prevent the post bracket (9A) from moving toward the rear of the passenger compartment. be prevented by.

In the above embodiment, the mounting piece 14 (j is molded separately, but the front end of the upper wall of the post bracket) 9A may be bent and molded integrally into an L-shape.

As described above, according to the present invention, the support member is provided across the dash side panels on both sides, and the middle part thereof is connected to the floor side via the stay to maintain the support rigidity. The front end of the post bracket that is attached to this support member and supports the steering column has an L-shaped upright edge and is connected to the dash upper panel via a mounting piece. Even if the dash upper panel protrudes toward the passenger compartment and becomes deformed in an accident.

stay. Support members are not affected by this modification. However, although there is a tendency for a pressing force to act on the post bracket in the main direction, the mounting piece absorbs this pressing force because its bent base edge is inverted, and after one chamber of the post bracket. This has a great practical effect in that it can completely prevent the steering system from moving backwards, thereby further increasing safety.
