摘要:
A steering column assembly of a vehicle has a rocker-arm lock device for locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The rocker-arm lock device has a slot in at least one of the housing and bracket and a carrier for longitudinal movement through the slot that is substantially perpendicular to a rotation axis of the steering shaft. An indexing apparatus of the device has first and second indexing rails carried by at least one of the housing and the bracket having the first slot and a carriage engaged rigidly to the carrier. A rocker arm of the apparatus is supported pivotally to the carriage about a rocker axis disposed substantially perpendicular to the carrier. The rocker arm carries first and second pads spaced diametrically outward from one another with respect to the rocker axis and facing laterally toward respective first and second indexing rails for selective engagement of at least one of the first and second pads to the respective first and second indexing rails.

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 lock the steering column with respect to the tilting movement. The second end of the cable is engaged with the tilt lock member such that the tilt lock member moves from the second unlocked position to the second locked position along the second path in response to rotation of the lever from the adjusting position to the locking position. The steering column assembly also includes a biasing device urging the tilt lock member to the locked position and cooperating with the lever to offset the force required to move the wedge lock from the first unlocked position to the first locked position along the first path.

A method for constraining an upper portion of a steering column assembly of a vehicle to translate along a preferred path comprises providing a telescoping steering column assembly with an upper column positioned for use by a vehicle operator and with a power assist module positioned remotely from the vehicle operator. A position lock bracket is disposed about the upper column, and the position lock bracket is conditionally fixed to the vehicle. A guide bracket is fixed to the vehicle and configured so as to constrain the upper column to translate along the preferred path.
