Abstract: A deformation device, especially for the steering column of a motor vehicle. The deformation device comprises a deformation tube (2), which can be deformed in a defined manner, as well as a deforming cone (1) associated with the deformation tube (2). The deformation device has at the deforming cone (1) at least one elevation (13, 28) or recess, whose edges (8) engage edges (9) of at least one impression (23, 25) or recess (10), whose shape corresponds to the elevation of the cone or the recess of the cone at the cone-side end of the deformation tube (2), in a positive (material blocking) manner, as a result of which essentially any desired high torque can be transmitted between the deformation tube (2) and the deforming cone (1) without any change in the good behavior in a collision.

Abstract: A motor vehicle steering column with a positioning device (1) is provided as well as a positioning device for motor vehicle steering columns.
