摘要： A clamp assembly secures a fixed portion of a steering column assembly to a movable portion of a steering column. It comprises a rack of teeth carried by the moving portion and a rack of teeth (111, 112) carried by the fixed portion and an inner hollow toothed block (120) nested inside an outer hollow toothed block (130), each carrying at least one rack of teeth with the rack- of teeth on the inner block tracing the rack of teeth on the moving portion and the rack of teeth on the outer block facing the rack of teeth on the fixed portion. A retaining clip (180) provides a lost motion coupling between the retaining clip and the inner toothed block (120) and an independent motion coupling between the retaining clip and the outer toothed block (130). First, second and third springs (140, 150, 160) bias the teeth of the blocks (120, 130) into and out of engagement with the racks when locked and unlocked. The assembly helps prevent damage to the teeth with the springs permitting the damage force on the blocks to be independently absorbed.

摘要： An adjustable steering column assembly includes a fixed rack secured to a first portion and a moving rack secured to a second portion, which are releasably engaged by a clamp mechanism to permit relative movement therebetween. The fixed rack comprises two rows of teeth spaced apart from one another.and extending towards each other. The moving rack also comprises two rows of teeth which extend away from each other. A clamp engaging means moves the moving rack into and out of engagement with the fixed rack. The teeth on the two racks are offset relative to one another. The mechanism is further arranged so that if a tooth on tooth event occurs the fixed rack interacts with the moving rack to cause the moving rack to move sideways to permit the teeth to become inter-engaged when the mechanism finally reaches the locked position.
