ABSTRACT:
A steering column having a pair of steering column members arranged coaxially about a first axis. One of the steering column members is axially movable along the first axis relative to the other steering column member. The steering column members are supported for angular movement about a second axis extending transverse to the first axis. A first lock releasably locks the members in one of a plurality of relative axial positions along the first axis. A second lock releasably locks the members in one of a plurality of angular positions about the second axis. A control lever is mounted for pivotal movement toward and away from a neutral position. An actuator operates in response to pivotal movement of the control lever away from the neutral position in a direction of desired movement of the one member to actuate one or both of the first and second locks to release the one member for movement to the desired position in the same direction in which the control lever is moved.
