A height-adjustable actuation device comprises a drive for height adjustment of the actuation device; a casing having a longitudinal axis; a hollow spindle arranged in the casing for displacement of a first lid arranged on the hollow spindle along the longitudinal axis; an internal spindle arranged inside the hollow spindle for displacement of a second lid arranged on the internal spindle along the longitudinal axis, with the hollow spindle and the internal spindle being non-rotatably connected to each other in terms of a rotation about the longitudinal axis, and with the hollow spindle and the internal spindle being displaceable relative to each other along the longitudinal axis.

Height-adjustable actuation device

The invention relates to an active impact protection system () for a knee area and/or a lower leg area of a vehicle occupant in a motor vehicle, particularly in a passenger car. The impact protection system () comprises an impact element () that can be extended toward the vehicle occupant out of a passive position and into an active position by means of a drive device (). A particularly advantageous design results when the impact element () is formed by a lid of a passenger-side glove compartment ().

Active impact protection system

A steering column damper for a power-driven vehicle comprises a jacket tube with a central longitudinal axis; a sliding tube displaceably guided in the jacket tube; a steering shaft, which is mounted for pivotability about the central longitudinal axis relative to the sliding tube and/or the jacket tube and guided through the jacket tube and the sliding tube; at least one working area, which is disposed between the jacket tube and the sliding tube and filled with a damping medium; at least one working-area-volume reduction unit, which is connected with the sliding tube, reducing the volume of the at least one working area upon insertion of the sliding tube into the jacket tube; at least one aperture which opens the at least one working area to ambience for discharge of the damping medium from the respective working area; a closing element for blocking the at least one aperture; and a triggering unit for controllable release of the respective closing element.

Steering column damper

An impact damper for supporting a bumper of a vehicle on the latter's chassis consists of two tubes one guided within the other, the external tube having at least one inwards-directed projection reinforced by a reinforcement ring and engaging with a suited depression of the internal tube. A deformation face is formed on the projection and tapers towards the axis of the tubes.

Impact damper for vehicles

A reversible impact damper is in series with an additionally provided irreversible deformation damper. The impact damper is a usual solid damper. The deformation damper has a deformation piston bearing against a piston rod of the impact damper on the one hand and on the other hand against crimps, which are formed in the wall of a slide tube displaceable relative to the housing of the impact damper and which are deformable.
