A steering column assembly of a vehicle has a rocker-arm lock device for locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The rocker-arm lock device has a slot in at least one of the housing and bracket and a carrier for longitudinal movement through the slot that is substantially perpendicular to a rotation axis of the steering shaft. An indexing apparatus of the device has first and second indexing rails carried by at least one of the housing and the bracket having the first slot and a carriage engaged rigidly to the carrier. A rocker arm of the apparatus is supported pivotally to the carriage about a rocker axis disposed substantially perpendicular to the carrier. The rocker arm carries first and second pads spaced diametrically outward from one another with respect to the rocker axis and facing laterally toward respective first and second indexing rails for selective engagement of at least one of the first and second pads to the respective first and second indexing rails.

A position control apparatus for a motor vehicle steering column includes an outer bracket, an inner bracket moveable relative to the outer bracket, and a jacket mounted to the inner bracket for telescoping movement along a longitudinal axis and for tilting movement. A first rack is mounted to the inner bracket and extends along the longitudinal axis. A first pinion is rotatable along the first rack during telescoping movement. A second rack is mounted to the outer bracket and extends angularly relative to the longitudinal axis. A second pinion is rotatable along the second rack during tilting movement. The first pinion has a first locking surface and the second pinion has a second locking surface. The first locking surface and the second locking surface may be engaged with each other to prevent telescoping and tilting movement or may be disengaged from each other to allow telescoping and tilting movement.
