In order to be able to reduce impact energy in this longitudinal adjusting arrangement in the case of a crash, at least one energy absorption element is fixed on at least one of the telescope sections, which energy absorption element, in the case of a movement, particularly an axial movement of the threaded spindle and/or of the spindle nut relative to the respective supporting telescope section, is acted upon by at least one of these parts of the spindle drive.

Abstract: In a steering lock for motor vehicles, a lock cylinder having a rotor and a stator is received in a tubular steering lock housing. A tubular end section of the lock housing and lock cylinder is enclosed by a pot-shaped cap made from a high strength material. In the steering lock housing, in a radially displaceable arrangement, there is mounted at least one locking element which is spring-biased .in the radial outward direction to protrude into an inner ring groove of the cap to prevent axial displacement of the cap when in a locked position. The at least one locking element can be slid, in a certain rotational setting of the rotor, into a notch in the rotor and can thereupon be moved out of the inner groove of the cap. For this displacement of the locking element into the notch of the rotor, there is secured along the base of the inner groove a circumferential spring wire.

Abstract: A protective device for motor vehicle airbag systems to protect the vehicle occupants utilizes a vessel whose wall piece, which can break out, is configured as part of the wall of a hollow valve block provided with the outflow orifice. The wall piece is equipped with an extension projecting into the interior of a valve block. The piston rod is guided displaceably, transversely relative to the extension in the valve block, and moved by a pyrotechnic propellent charge. The rod serves to break out the wall part and is provided with a collar which, in the event of ignition, strikes against the extension and thus leads not to a violent breaking-out, but to a pivoting of the wall piece before the final breaking-out.

Abstract: A motor vehicle steering wheel has flat steel deformable spokes which connect a steering-wheel rim to a hub to be mounted on a steering shaft. The associated free ends of the spokes are cast into the cast hub, and each spoke has in the cast-in area a passage bore which extends in the axial direction of the steering wheel and penetrated by the hub material during the casting process. In order to achieve an increase in rigidity in the hub/spokes connecting area, the passage bore is arranged directly adjacent to the entry area of the spoke into the hub, forming a rolling step, such that in this area a tension-rod connection is formed between the hub material located above and below the spoke.

Abstract: An axially adjustable steering column for vehicles is disclosed which has an axially displaceable steering shaft which is surrounded by two steering column jacket parts which can be pushed together in a telescopic fashion. The jacket parts can be attached to one another by way of a clamp connection. The jacket parts are axially movable with respect to one another when the clamp connection is loosened with the displacement of the steering shaft. The clamp connection has at least one threaded pin which is radially movable with respect to the longitudinal axis of the steering column jacket parts and is received on the outer steering column jacket part in a threaded section and after its screwing-in movement presses against the internal steering column jacket part. A spring-loaded control cable is provided which acts in a rotating fashion on the threaded pin.

Abstract: An adjusting device to vary the inclination of a steering column of a motor vehicle comprises a rectangular frame which surrounds a casing tube accommodating the steering column, braces the same against the vehicle body and acts additionally as a guide lever for pivotal adjusting movement of the steering column. A motor driven adjusting mechanism is anchored at a fixed angle to the frame and to the casing tube and operates to pivotally adjust the steering column inclination.

Abstract: An antiremoval device for a locking mechanism for a steering column lock for motor vehicles is disclosed. A fastening member extending through releasably connected housing parts, which prevent tampering with the locking parts, engages additionally into a displaceable catch of the locking parts when the catch is in a locking position with the steering column to thereby prevent the fastening member from being moved to a position releasing the housing parts.

Abstract: An unlocking prevention device for a steering wheel lock of that type having a driver acting on a detent pin and controlled by a locking cylinder shaft. During the unlawful removal of the locking cylinder, the shaft is shifted in its pull out direction by means of a force and the driver thereby engages into a groove, as a result of which the shaft cannot be removed and, because of the changed form of the shaft, the driver can no longer be actuated.

Abstract: A driving connection between spline shafts and spline bore hubs of safety steering columns, where the shaft and the hub, because of prestressing torque existing between the two, can be shifted with respect to one another axially but are free from torsional play. The prestressing torque is generated by a torsion spring element supported between the shaft and the hub. The required freedom from torsional play is achieved by arranging a main hub and an additional hub on the shaft with the torsion spring element connecting the main hub with the additional hub so that the main hub and the additional hub are spring loaded in opposite rotational directions.

Abstract: An automobile steering wheel that is disposed below a plane of a steering wheel rim. As a protection against impact, there is a plastically deformable cup-like deformation member within the steering wheel that absorbs energy due to an impact of a driver of the motor vehicle on the steering wheel. Spokes are constructed in such a manner that the contribute to the energy absorption by a performance of deformation work. The deformation member has a height which is less than a distance between the hub and the plane of the steering wheel rim. The deformation member is fixedly connected in its upper region with the respective spokes.
