Steering lock for a motor vehicle

摘要

The anti-theft lock (10) comprises a casing (12) in which a bolt (14) rotates between rest and operating positions. In the rest position a key can be introduced or withdrawn axially and in the operating position the key cannot be withdrawn. The bolt comprises a rotating output part (46) which controls radial displacement of a latch (82) between locking and retracted positions. The bolt slides axially in the casing (18) between a rest position, which it occupies in the absence of a key, and an active position which it occupies when the key is introduced into the bolt. The output part comprises a crankpin (54) which engages a control cam on the latch for controlling its displacement. The latch has an axially projecting locking finger (148) which enters a housing (66) in a radial end face (50) when the latch is in the locked position. This prevents displacement of the latch towards its retracted position. The finger is withdrawn during rotation of the bolt from its rest position towards its active position.
