ABSTRACT:
A coincidental lock for a motor vehicle comprises a key controlled lock cylinder mounted in the axial bore of a housing for rotation 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locking position and a latch on the lock bolt maintains the lock bolt in the retracted position until the key has been withdrawn from the lock cylinder. An axially extending driver element is keyed to the lock cylinder for rotation therewith and is axially displaceable with respect to the lock cylinder into operative association with an electrical ignition circuit for starting the motor of the vehicle and is arranged to operate the circuit on rotation of the lock cylinder into a selected operating position. A control is arranged on the lock bolt for displacing the driver element axially upon movement of the lock bolt between the retracted and locking positions.
