An adjustment device for vehicle steering columns has a steering shaft to which a steering element can be attached, and a drive unit for adjusting a length of the steering shaft. The steering shaft has at least two tubes, which engage into each other in a telescoping manner, can be moved relative to each other, and can in each case be driven by a drive unit. The two drive units are arranged next to each other in the region below the adjustment device. If the two tubes are inserted into each other, the adjustment device only has a short length, which is measured in the displacement direction of the tubes. Conversely, if the tubes are extended in a telescoping manner, a very large length adjustment range can be achieved despite the short length in the starting position.

Adjustment device for steering columns of vehicles

A compact adjustment device for steering columns of vehicles has a length-adjustable steering shaft to which a steering element can be connected. It includes at least one drive unit for length adjustment of the steering shaft. The steering shaft has a guide tube which is non-displaceably connected to a holder and into which an axially displaceable inner tube projects. It is drive-connected to the drive unit and can be connected to the steering element. Only a single drive unit is required to adjust the length of the steering shaft. It is used to axially move the inner tube to change the length of the steering shaft. The steering element is attached to the inner tube and can then be adjusted to the most favorable driving position using the inner tube. Since only one drive unit is required for the length adjustment, the design effort of the adjustment device is limited.

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.
