Automobile steering wheel locking device has ratchet element moved into partially released position in which removal of locking device is prevented before movement into fully released position

摘要

The locking device has a carrier body attached to the mantle sleeve (3) enclosing the steering axis (1) and an actuator, controlled via a control unit, for operation of a control mechanism with a ratchet element, displaced transverse to the steering axis, for engaging in a ratchet notch. The control mechanism, the carrier body (7) and the ratchet element are arranged so that the latter is moved initially into a released position in which it engages in a window (3a) of the mantle sleeve, preventing removal of the locking device, before movement into a fully released position allowing its removal.
