The invention relates to a steering device for motor vehicles, comprising a steering shaft that is guided by a guide box ( ) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface ( ) along the axis of the shaft ( ) which allows for a displacement path ( ) with respect to the chassis ( ) in the case of a collision. Clamping means ( ) are provided for axial retention of the console ( ) in an initial position of said displacement path ( ). Spacers ( ) are provided inbetween the sliding surfaces ( ) at a distance from the clamping means ( ). When clamping occurs, said spacers cause flexural warping of the retaining device and increase the stability of the device.

Steering-column crash system

A steering device for motor vehicles has a steering shaft that is guided by a guide box ( ) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface ( ) along the axis of the shaft ( ) which allows for a displacement path ( ) with respect to the chassis ( ) in case of a collision. A clamp ( ) is provided for axial retention of the console ( ) in an initial position of the displacement path ( ). In this way at least one part of the clamped surface is slanted in relation to the vertical clamping device so that the clamping surfaces can move away from each other when the steering shaft is displaced and clamping is reduced.

Steering column crash system

A steering device for motor vehicles having a chassis, includes a steering shaft with a shaft axis, a guide box for guiding the steering shaft and a retaining bracket clamped to the guide box. The bracket has at least one slide face along the shaft axis and the slide face has a slot defining a displacement path with respect to the chassis. A clamping mechanism axially retains the bracket in an initial position of the displacement path and a tear frame with a slide face is clamped by the slide face of the bracket against the chassis and is also clamped by the clamping mechanism relative to the chassis. A tear-away strip is located between a pair of notched tracks on the tear frame and has at one end a retaining flap which is fixed to the bracket.
