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.

Abstract: A bearing device for motor vehicle shafts is described, in particular for motor vehicle steering shafts. The bearing device is provided for torque transmission between an inner shaft and the hollow shaft surrounded by the inner shaft. The inner shaft and the hollow shaft each have opposing bearing grooves, in which rolling elements are received. At least one positive locking cam in radial direction is provided. A safety contour is assigned to the positive locking cam, the safety contour comprising two engagement positions for the positive locking cam. In the case of unoccupied bearing grooves the positive locking cam is rotationally movable along the safety contour between the engagement points during a torque transmission, in a manner that a defined relative movement between the inner shaft and the hollow shaft is possible, which generates both tactile feedback and acoustic feedback. Furthermore, an automotive shaft assembly is described.
