Abstract: A steering device for motor vehicles, which is adjustable along its longitudinal axis and whose steering column can be telescopically extended and retracted by means of a drive device, the steering column jacket being designed in several parts, one steering column jacket part being fixed to the body and one steering column jacket part being movable relative to the first, and in which adjustment can be introduced into the steering column jacket movable part by means of a coupling element with which a worm gear driven by a drive motor engages. The coupling element consists of a toothed rack located on the periphery of the steering column jacket movable part, a worm gear located with its axis parallel to the rack engaging with the rack and passing through a recess in the steering column jacket fixed part. The engagement angle of the worm gear is so dimensioned that self-locking occurs.

Abstract: An internal combustion engine arranged in an automotive vehicle with optionally driven units or the like, for example, units driven by way of pulleys. The units extend toward a front if the internal combustion engine is arranged in a front compartment of the automotive vehicle and extend toward the rear beyond the internal combustion engine if the engine is disposed in a rear compartment. The units and optionally their drive elements are fashioned in such a way and/or are mounted to the internal combustion engine in such a manner that, in case of a collision, impact energy is absorbed at the units and/or their fasteners or mounting by the performance of deformation work, by overcoming frictional resistances, and/or by a displacement of viscous substances against a resistance.

Abstract: An arrangement for mounting driven or non-driven assemblies on or to an internal combustion engine mounted in a motor vehicle. The assemblies projecting forward beyond an end of the internal combustion engine when the engine is mounted in a front of the motor vehicle and projecting rearwardly beyond the engine when the engine is mounted in the rear of the motor vehicle. The assemblies are so mounted and/or fastened on or to the internal combustion engine that, in the event of a collision and/or an impact on the assemblies, such assemblies are displaceable in a direction of the internal combustion engine with a zero resistance and without expending any energy absorption.
