Abstract

A process is disclosed for fixing a motor vehicle steering column. The, motor vehicle steering column is adjustable in the axial and/or vertical direction and has a steering shaft and a housing accommodating the steering shaft, on a bracket of the steering column of the motor vehicle, which bracket is a rigid part of the body. In the case of an accident, a positive-locking connection is established by pyrotechnical device between the adjustable steering column housing and the bracket of the steering column, at the moment of the impact of the motor vehicle against an obstacle. A device for carrying about the above-mentioned process is disclosed, in which at least one pyrotechnical module and at least one element, which can be controlled by the pyrotechnical module, are present for the positive-locking connection between the steering column and the bracket, which is a rigid part of the body.
