Abstract
Abstract A steering shaft lock equipped with a lock cylinder and an ignition start switch, particularly for automotive vehicles, which comprises a steering column including a steering shaft. A locking latch locks the rotary movement of the steering shaft and a spring urges the locking catch into locking position. A keyoperated eccentric has a shaft and the locking latch is withdrawable by the eccentric against the action of the spring and returned into locking position due to the effect of the spring upon release by removal of the key, to lock the locking latch against return pressure. Also a separate locking catch arrests the locking latch against return movement in its locking position and is controllable exclusively by the eccentric into a freeing position.
