  • Patent number: 10414375
    Abstract: Lock cylinder for an ignition starter switch or a wheel lock at a vehicle with a cylinder core which is at least pivotably received in a cylinder housing. At least one blocking member prevents a rotation of the cylinder core in the cylinder housing in a blocking position and in a releasing position releases a rotation in the cylinder housing. A key channel extends through the cylinder core in which a key is insertable and with which the blocking member is movable between the blocking position and the releasing position. At least two rotation positions can be occupied. In the off-position a key is insertable and detractable in the key channel and in the starting position a vehicle starter can be switched on. A mechanical resetting block prevents a resetting of the cylinder core from the starting position to the off-position by a simple rotation of the cylinder core.

  • Patent number: 6810702
    Abstract: A lock for irrotationally locking a motor-vehicle steering column enclosed by a tubular housing, the lock including a lock element displaceable to-and-fro between a locked and a released position and further a drive motor driving the locking element. For greater compactness, to offer enhanced security against theft, and to leave unhampered the telescoping of the steering pillar composed of steering column and tubular housing, further to reduce the danger of knee injury in case of accident, the locking element is mounted in the vicinity of the steering-wheel side end of the steering column inside the tubular housing, and the drive motor is mounted next to the foot-space side end of the steering column, and the drive motor cooperates with the locking element through a connecting element arrange inside the tubular housing.

  • Patent number: 6779371
    Abstract: The aim of the invention is to provide a steering column lock with improved break-up safety. To this end, a spring-loaded locking pin (30) is integrated into the peripheral cam (12), said locking pin being co-rotated when a rotor (10) pertaining to the steering column lock is rotated. In the test position (30.1) of the locking pin (30), the pin is aligned with a locking recess (38) in the housing (1) while in a working position of the motor (10) that is obtained by access authorization means, it is not. Normally, the locking pin (30) is inactive since it is maintained in a retracted position by a spring-loaded (47) feeler (40). When the rotor (10) is missing, the feeler (40), due to its spring load (27), releases the locking pin (30). If in this case the rotor (10) is in the rest position, the locking pin (30) engages in the locking recess (38) of the housing (11) and blocks rotation.

  • Patent number: 5848540
    Abstract: A motor vehicle steering column lock includes a drove rod element extending axially along a bore within the housing of the steering column lock for actuating a steering column locking bolt member in accordance with known steering column lock mechanisms. The drive rod element of the steering column lock is provided with a radial projection that cooperates with a radial wall of an enlarged recess of the bore extending through the lock housing for preventing axial withdrawal of the drive rod element from the housing and also includes an axial locking projection that is spring biased into a locking recess for preventing relative rotation between the drive rod element and the housing when the steering column lock is transported or stored without a lock cylinder installed in the housing.
