A steering column includes an adjustment unit having a steering spindle rotatably supported in a casing pipe about a longitudinal axis. A carrier unit configured to receive the casing pipe includes at least one clamping face facing the casing pipe. A clamping device clamps the clamping face against the casing pipe to longitudinally fix the adjustment unit relative to the carrier unit, releases the clamping face from the casing pipe and releases an adjustment of the adjustment unit relative to the carrier unit at least in the longitudinal direction. The carrier unit includes at least one sliding face facing the casing pipe along which the casing pipe can be moved longitudinally in the release position. The sliding face may be arranged on a support device which presses the sliding face against the casing pipe with a support force which can be predetermined independently of the clamping force.

Steering column for a motor vehicle

A steering column may include a steering spindle mounted rotatably about its longitudinal axis in an inner casing tube. An outer casing unit in which the inner casing tube is held may be directly or indirectly connectable to a body of a motor vehicle. A clamping device in a fixing position affixes the outer casing unit relative to the inner casing tube. In a release position, the clamping device permits adjustment of the inner casing tube relative to the outer casing unit at least in a longitudinal direction. The clamping device may have at least one locking part for prohibiting or permitting movement between the inner casing tube and the outer casing unit. The inner casing tube and the outer casing unit may be coupled by an energy absorption device that has at least two energy absorption elements that are plastically deformed in the event of displacement between the inner casing tube and the outer casing unit.

The invention relates to a steering column for a motor vehicle, wherein the steering column comprises a steering spindle bearing unit and a steering spindle mounted in the steering spindle bearing unit so as to be rotatable about a steering spindle longitudinal axis, and a support unit, which is provided in the motor vehicle for fixing the steering column and against which the steering spindle bearing unit is retained. The steering spindle bearing unit has a thread and can be adjusted by means of a motor along the steering spindle longitudinal axis relative to the support unit, wherein the steering spindle bearing unit, for adjustment thereof along the steering spindle longitudinal axis relative to the support unit, is connected by means of at least one drive belt or at least one drive chain to the motor.
