Abstract:
A column lock assembly for a vehicle including a steering shaft rotatable about a longitudinal axis is disclosed. A first abutment defining a plurality of recesses and a second abutment are mounted to the steering shaft. A sleeve is disposed between the abutments with a locking member movable between a locked position preventing rotation of the sleeve and an unlocked position allowing rotation of the sleeve. The sleeve includes a body portion and a first protrusion engaging one of the recesses to couple the sleeve to the steering shaft for concurrent rotation about the longitudinal axis with the body portion being deformable along the longitudinal axis to move the first protrusion from one of the recesses to an other one of the recesses for allowing rotation of the steering shaft relative to the sleeve when the locking member is in the locked position.
