Abstract
An anti-theft steering shaft lock on an automotive steering column including a first clutch element on a rotatable steering shaft and a second clutch element on a stationary part of the steering column. The first clutch element has notches accessible in the direction of the centerline of the steering shaft and the second clutch element has axial lugs for engagement in the notches. The second clutch element is mounted on the stationary part of the steering column for bodily movement in the direction of the centerline of the steering shaft between locked and unlocked positions relative to the first clutch element. An annular control element is rotatably supported on the stationary part of the steering column around the second clutch element and has a circumferential cam slot which receives a radial lug on the second clutch element such that rotation of the control element effects bodily shiftable movement of the second clutch element between its locked and unlocked positions. An actuating system on the stationary part of the steering column for rotating the control element includes a cylinder lock and a double rack and pinion.
