STEERING COLUMN SUPPORT CONSTRUCTION

摘要

Provided is steering column support construction that together with eliminating strong rubbing between the bottom surface of a vehicle-side bracket 23a and the top surface of a column-side bracket 22a, and keeping the absolute value and fluctuation in the break away load small, more completely protects the driver during a collision accident without lowering the freedom of design of the steering apparatus. An adjustment rod 27 for adjusting the position of a steering wheel is provided on the top side of a steering column 6b. During a secondary collision, a moment that is applied to the column-side bracket 22a is kept small, friction at the area of rubbing between the column-side bracket 22a and the vehicle-side bracket 23a is reduced, and the break away load is kept low. Moreover, the driver's knees are protected by eliminating the portion that protrudes further downward than the steering column 6b.

主权项

1. A steering column support construction, comprising:
a displacement-side bracket that is fastened to a top side portion of a middle section of a steering column; a vehicle-side bracket that has a locking section with material removed that is formed in a middle section in a width direction thereof, and that is fastened to a vehicle body side in at least two locations on both sides in the width direction of the locking section with material removed; a column-side bracket having a pair of left and right support plate sections that are located on both sides of the displacement-side bracket; a locking member that together with being fastened to the column-side bracket, engages with the locking section with material removed; an adjustment rod that, with the displacement-side bracket held between the support plate sections, is inserted in the width direction through the displacement side bracket and is spanned between the support plate sections; and a pair of pressure sections that are provided on both end sections of the adjustment rod; and by expanding or contracting a space between the pressure sections, it is possible to fasten or adjust a position of the displacement-bracket with respect to the column-side bracket, and the column-side bracket and locking member are supported with respect to the vehicle-side bracket so as to be able to break away in a forward direction thereof.
