ABSTRACT:
A tilt telescope steering column comprises a bracket pivotably supporting a housing between first and second pivot limits. The first and second pivot limits may be changed. A pair of screws attach the housing to the bracket and clearance between the screws and the housing is taken up. A tubular member is located within the housing and is axially movable relative to the housing. Axially spaced bearings engage the housing and the tubular member to take up clearance therebetween. A tilt blocking mechanism includes a lock member carried by the housing and movable to a position blocking relative pivotal movement between the housing and the bracket. The lock member is moved against a surface of the housing when the lock member is in its blocking position to take up clearance between the lock member and the housing. A telescope blocking mechanism includes a lock pin which is movable to a position blocking relative axial movement of the tubular member and the housing. A cam member is supported for pivotal movement by the lock pin. The lock pin is moved away from its blocking position in response to the cam pivoting in a first direction. The lock member is moved away from its blocking position in response to the cam pivoting in a second direction opposite the first direction.
