Abstract

A steering column assembly has a steering column with a longitudinal axis and disposable in a vehicle for tilting movement and telescoping movement. A wedge lock is engaged with the steering column and moveable between a first unlocked position and a first locked position along a first path to selectively lock the steering column with respect to the telescoping movement. A force required to move the wedge lock increases along the first path from the first unlocked position to the first locked position. A lever is pivotally engaged with the steering column about a pivot axis for rotation between an adjusting position and a locking position. The wedge lock moves from the first unlocked position to the first locked position along the first path in response to rotation of the lever from the adjusting position to the locking position. A cable assembly includes a cable with first and second ends and a sheath substantially encircling the cable. The first end is engaged with the lever to move in response to rotation of the lever. A tilt lock member engaged with the steering column is moveable between a second unlocked position and a second locked position along a second path to selectively…
