Abstract
A steering column assembly includes a column jacket coupled to a support bracket. The column jacket is moveable in a longitudinal direction along a longitudinal axis and in a pivotable direction relative to the support bracket about a pivot axis. A locking mechanism interconnects the support bracket and the column jacket, and includes a torsion shaft rotatable about a shaft axis in a first direction and a second direction to move the locking mechanism between a lock position and a release position. A motor includes an output shaft rotatable about a primary axis in a single rotational direction. A linkage interconnects the motor and the torsion shaft of the locking mechanism. The linkage is actuated by rotation of the output shaft in the single rotational direction to rotate the torsion shaft in alternating fashion between the first direction and the second direction.
