The lock consists of a tubular housing (12) fixed to the steering column tube (18) and extending transversely relative to a hole (44) in the tube. The housing contains a lock with a drive mechanism (20) and a guide tube (22) which has one end (42) extending axially through the steering column tube hole (18) and is designed to guide a bolt (24) between retracted and extended positions, engaging in the latter position with a socket in the steering shaft. The bolt guide tube comprises a main section (22) which is connected to the drive mechanism, and an end section (42) which can slide axially relative to the main section and is connected to it by a spring (52). The end section of the guide tube is able to slide through the steering column tube hole (18) as far as a stop collar (54) on its outer surface allows. In a variant of the design the relative movement between the main and end sections of the guide tube is controlled by a system of lugs and slots. |
