  • Publication number: 20090133453
    Abstract: An electric steering lock for a drive authorization system in a motor vehicle, including a movable locking element which, according to a first position, can be brought into locking engagement with a latched-in position on the steering shaft in the steering wheel column and, according to a second position, can be brought out of locking engagement with said position. The steering lock also has a drive for moving the locking element between the two positions, and electronics for controlling the drive. The system may have an associated second device in the form of an electronic key, an identification (ID) transmitter, a chip card or the like, with the result that, when the second device is authorized, the drive can be controlled into the respective position by the electronics. The electronics generate those signals which are used to trigger functions which can otherwise be effected by an electric ignition lock.

  • Publication number: 20080028807
    Abstract: An ignition lock for a motor vehicle includes a carrier element for holding an ignition key that is inserted in the ignition lock. The carrier element is movable along a longitudinal axis of the ignition lock. The carrier element pushes a slide bar from a blocking position to an unblocking position when the carrier element moves along the longitudinal axis. A latch bar, when in its latching position, restricts a movement of the carrier element along the longitudinal axis and, when in its unlatching position, allows the carrier element to move along the longitudinal axis. When the latch bar is in its unlatching position and the slide bar is in its blocking position, the slide bar prevents the latch bar from moving from the unlatching position to the latching position.

  • Publication number: 20060071555
    Abstract: An engine (9) of a vehicle (1) is started by first inserting an ignition key (3) into an ignition lock (2) of the vehicle (1). The vehicle (1) can be started by merely pressing the inserted ignition key, whereby said ignition key (3) is further inserted into the ignition lock (2) and takes in a nearly flush position with a dashboard (4) within which the ignition lock is disposed when the motor runs such that the ignition key (3) does not constitute a potential hazard in the event of an accident. The engine (9) is stopped by once again pressing the ignition key (3). Once the engine (9) has been stopped, the ignition key (3) is brought into a position in which the same can be simply removed from the ignition lock (2) by the driver.
