ABSTRACT:
An improved key-operated steering shaft locking device for a motor vehicle is disclosed. The device comprises a rotatable lock cylinder, a spring, and a latch movable between steering shaft locking and unlocking positions, the latch being operatively associated with the cylinder so that rotation of the latter causes axial movement of the former perpendicular to the axis of rotation of the cylinder from the locked to the unlocked position; the latch is also operatively associated so that the spring urges the latch toward the locked position. The improved device further comprises means including a rocker arm pinned for rotational movement between a first position wherein a portion of the arm extends into the key slot of the cylinder and the means is ineffective to lock the latch in the position where the shaft is unlocked, and a second position wherein the arm does not extend into the key slot and the means is effective to lock the latch in the position where the shaft is unlocked.
