Abstract
A steering column assembly for a motor vehicle is adjustable in both rake and telescope directions and then locked in a convenient setting by a driver. The locking mechanism for the telescope and rake adjust is motor actuated in response to activation of a toggle switch. The motor can be proximate or remote from the locking mechanism and the steering column assembly. A transmission operates on a rotating cam principal which alternately cycles a clamp of the locking mechanism between locked and unlocked conditions. A drive shaft extends between the motor and the locking mechanism and can be either rigid or flexible. Locking the steering column assembly in an adjusted position can be accomplished either by compressing a capsule bracket against a compression bracket, or via interlocking engagement of pawls with corresponding teeth in respective slots in the capsule and compression brackets.
