Abstract

The invention relates to a locking device for an adjustable steering column for a motor vehicle, wherein the locking device has a cam bracket having at least one cam arranged in a fixed manner thereon and at least one mating cam bracket having at least one mating cam arranged in a fixed manner thereon and at least one stop. The cam bracket and the mating cam bracket are arranged so as to be rotatable relative to each other around an axis of rotation, and the cam of the first cam bracket interacts with the mating cam of the mating cam bracket upon rotation of the cam bracket and mating cam bracket relative to each other around the axis of rotation in order to generate a stroke in the longitudinal direction of the axis of rotation. The locking device has at least one dampening body which has at least one elastically deformable material that is softer than the cam bracket and the stop, wherein the cam bracket, upon rotation of the cam bracket and the mating cam bracket relative to each other around the axis of rotation, contacts the stop in a stop position in such a way that the dampening body is positioned therebetween.
