A deformation device, especially for the steering column of a motor vehicle. The deformation device comprises a deformation tube (), which can be deformed in a defined manner, as well as a deforming cone () associated with the deformation tube (). The deformation device has at the deforming cone () at least one elevation () or recess, whose edges () engage edges () of at least one impression () or recess (), whose shape corresponds to the elevation of the cone or the recess of the cone at the cone-side end of the deformation tube (), in a positive (material blocking) manner, as a result of which essentially any desired high torque can be transmitted between the deformation tube () and the deforming cone () without any change in the good behavior in a collision. The design of deformation devices, especially for steering lines of motor vehicles, can be substantially simplified and despite the improvement in product quality that is made possible, considerable cost savings are achieved in the manufacture of steering line components for motor vehicles.

Deformation device for a steering column

An electrically adjustable steering column as it is used in motor vehicles. The present invention pertains, in particular, to a steering column that has at least two adjusting units, which are arranged on an adjusting spindle and can be moved in the axial direction of the adjusting spindle. The steering column comprises according to the present invention:
