Abstract

A steering column assembly including a steering column that extends between a first end and a second end and includes a hand wheel location on the first end and a rotation output on the second end. The steering column comprising an upper jacket, a lower jacket, and a sliding bracket, wherein the upper jacket is telescopically connected to the lower jacket and the lower jacket is slidably connected to the sliding bracket. A telescopic actuator extends between the sliding bracket and the upper jacket and facilitates relative telescopic movement between the upper jacket and the lower jacket and slidable movement between the lower jacket and the sling bracket. The lower jacket including a shaft connected to the rotation output via a splined inner bore that permits axial play. The movement of the lower jacket resulting in translational movement of the shaft.
