<p>A motor vehicle steering column lock includes a locking element that is movable reciprocally by a rotatable control element between a locked and an unlocked position. The control element extends around the locking element and includes two inner bevel surfaces and four terminal surfaces cooperating with two radial locking element projections that are arranged diametrically opposite to each other relative to the control element's axis of rotation. The projections each engage at their ends a bevel surface or one of its two terminal surfaces located in planes extending orthogonal to the control element's axis of rotation. One of the bevel surfaces and its terminal surfaces are offset in the direction of the control element's axis of rotation relative to the other bevel surface and its terminal surfaces, and they are located at a larger distance from and around the control element's axis of rotation as compared with the distance of the other bevel surface and its terminal surfaces from the axis of rotation of the control element. The projections are stationary, and the projection cooperating with the bevel surface that is located farther away from the control element's axis of rotation and with its terminal surfaces is commensurately offset from the projection cooperating with the other bevel surface and with its terminal surfaces along the direction of the control element's axis of rotation, with the former projection having a commensurately longer length than the latter.</p> |
