Abstract
A steering column is disclosed for a motor vehicle, including an actuating unit, in which a steering spindle is rotatably mounted about a longitudinal axis. The actuating unit includes a casing unit which has at least three casing tubes which are arranged so as to be axially telescopable relative to one another. One of the casing tubes forms an outer casing tube in which at least one intermediate casing tube, in which an inner casing tube is accommodated, is accommodated. Rolling bodies are arranged between the casing tubes such that they are able to roll in the axial direction. First rolling bodies are arranged between the outer casing tube and the intermediate casing tube, and second rolling bodies are arranged between the intermediate casing tube and the inner casing tube, the first rolling bodies being arranged offset in the circumferential direction relative to the second rolling bodies.
