Disclosed is an electronic steering wheel lock for motor vehicles, comprising a rotor (5) that is rotatable within a stator (2) from an initial position and back into said initial position so as to move a locking member (3) back and forth between a steering shaft-locking position and a steering shaft-releasing position. In its initial position, said rotor (5) can be coupled in a positive manner to the stator (2) under the effect of a spring load (22) while being movable within the stator (2) in an axial direction against the effect of the spring load (22) by means of an electromagnet (7) disposed coaxially to the rotor (5) in order to cancel the mutual engagement between the rotor (5) and the stator (2) and allow the locking member (3) to be moved into the steering shaft-releasing position when the electromagnet (7) is excited with the aid of an electronic key. The rotor (5) is provided with at least one coupling dog (23) which cooperates with a coupling slot (24) of the stator (2). Said coupling slot (24) is delimited by an inertial element (26) on the side towards which the rotor (5) is rotatable within the stator (2) from the initial position thereof. The inertial element (26) can be displaced within the stator (2) along with the rotor (5) against the effect of a spring load (27) when the rotor (5) is moved in axial direction against the effect of the spring load (22) thereof as a result of a blow being inflicted on the stator (2). Said mechanism of protection against blow effects can also be provided in a corresponding electronic ignition and starting switch for motor vehicles.
An electronic steering wheel lock for motor vehicles, which can be unlocked by means of an electronic key, comprising a locking member for locking the motor vehicle steering shaft against rotation and a rotor that is rotatable out of an initial position and back into the initial position for moving the locking member back and forth between a steering shaft locking position and a steering shaft releasing position in a stator, wherein the rotor cannot be rotated out of the initial position, so that the locking member moves into the steering shaft releasing position, until an electromagnet, disposed in the stator coaxially with the rotor, has been energized with the aid of the electronic key, in order to unlock the rotor, which in its initial position, under the influence of a spring load, can be coupled positively with the stator and is axially displaceable in the stator by means of the electromagnet against the action of the spring load in order to release the mutual engagement of the rotor and the stator, and further wherein the rotor has at least one coupling dog, which cooperates with a coupling slot of the stator, which slot is defined, on the side toward which the rotor is rotatable out of its initial position, by an inertial element which is displaceable in the stator together with the rotor against the action of a spring load when the rotor (5), as a consequence of a blow on the stator, is axially displaced against the action of its spring load.
An electronic ignition and starting switch for motor vehicles, which can be unlocked by means of an electronic key, comprises a rotor, which for switching on and off, in particular the ignition system and the starter of the motor vehicle, is rotatable in a stator out of an initial position into various switching positions and back into the initial position, wherein the rotor cannot be rotated into the switching positions until an electromagnet, disposed in the stator coaxially with the rotor, has been excited with the aid of the electronic key in order to unlock the rotor, which in its initial position, under the influence of a spring load, can be coupled positively with the stator, and is axially displaceable in the stator by means of the electromagnet against the action of the spring load in order to release the mutual engagement of the rotor and the stator, wherein the rotor has at least one coupling dog, which cooperates with a coupling slot of the stator, which slot is defined, on the side toward which the rotor is rotatable out of its initial position, by an inertial element which is displaceable in the stator together with the rotor against the action of a spring load when the rotor, as a consequence of a blow on the stator, is axially displaced against the action of its spring load.
