Abstract: The steering column adjusting device for vehicles, preferably commercial vehicles, has a basic unit, with respect to which an adjusting unit is adjustable. With the adjusting unit, a steering spindle can be adjusted. In its respective position, the adjusting unit can be clamped with respect to the basic unit with at least one clamping device. The clamping device is pivotably mounted on the adjusting unit.

Abstract: 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.
