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 between an outward and an inward position, 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 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 arranged for engagement with the latch member in the retracted position and carrying a cam projecting from the control ring towards the lock bolt. A leaf spring on the lock bolt cooperates with the cam to press the lock cylinder axially outwardly in a ready-to-lock position.
