Device for positioning an automobile vehicle steering column in the event of an impact

摘要

A steering column includes a steering shaft freely rotatable in a tube-body disposed in a support member attached to a chassis of the vehicle. The tube-body is locked by a system for adjusting its position. The positioning device comprises an additional guide system for the tube-body in the event of an impact such that the angle of the steering shaft and the steering wheel of the vehicle to the horizontal plane is smaller after retraction of the steering wheel in order to allow correct functioning of the air-bag.
