ABSTRACT:
A coincidental lock for a motor vehicle comprises a key controlled lock cylinder mounted in the axial bore of a housing for axial displacement and for rotation in its inward position into selected operating positions. A lock bolt is mounted in a cross bore of the housing for displacement between a retracted and a locking position for the steering column of the vehicle. A spring biases the lock bolt into the locking position and displaces the lock cylinder outwardly, and a latch member on the lock bolt maintains the lock bolt in the retracted position when the lock cylinder is in the inward position. A driving member operated by the rotation of the lock displaces the bolt against the spring bias into the retracted position and includes a control ring and, eccentrically arranged thereon, a first cam, a second arcuate cam having an oblique camming face for engagement with the latch member in the retracted position and a third cam projecting from the control ring towards the lock bolt and having an oblique camming face. A fourth cam on the lock bolt cooperates with the third cam to position its camming face in subtending engagement with the fourth cam in a ready-to-lock position.
