Abstract
A steering column assembly (10) including a mounting structure (20); a column housing (50) having a wall opening (54) and being fixed in position for upward and downward pivotal motion; a tilt screw (72) having a threaded shank and a gear; a tilt nut (80) and optionally a bushing surrounding the tilt nut positioned at least partially within and contacting a surface defining wall opening (54) and having a threaded bore adapted to receive the tilt screw, the contact between the tilt nut and the wall opening such that the load transmitted from the wall opening to the tilt nut is substantially on axis with the threaded bore; a motor (96) for raising and lowering the column housing by rotating the gear portion and causing the tilt nut to advance toward or away from the gear, causing the column housing to raise or lower, and wherein the longitudinal axis of the threaded shank can pivot fore or aft as the column housing is raised or lowered.
