Abstract:
A steering column for a vehicle is disclosed, comprising at least one telescope-like portion and a carrier portion. The telescope-like portion is supported so as to be displaceable inside the carrier portion in the longitudinal direction of the telescope-like portion and has an adjustment device for telescopic adjustment of a length of the steering column by pushing the telescope-like portion in or out with respect to the carrier portion, and a ball bearing device between the telescope-like portion and the carrier portion. A running groove arrangement of the ball bearing device is formed with a linear running groove on the telescope-like portion and on the carrier portion and a plurality of balls are arranged between the running groove of the telescope-like portion and the running groove of the carrier portion. In order to improve rigidity and/or to achieve self-centering and/or to reduce friction between the balls and running grooves, the steering column, the ball bearing device has a plurality of running groove arrangements. The plurality of running groove arrangements are arranged in a state distributed about a longitudinal center axis of the steering column.
