Abstract
A steering column for a motor vehicle comprises a covering unit. A steering spindle is rotatably supported about a longitudinal axis which extends in a longitudinal direction. At least three covering elements can be displaced in a telescope-like manner in a longitudinal direction and which comprise at least one internal covering, an external covering and an intermediate element. A motorised displacement drive includes a first spindle drive arranged between the internal covering and the intermediate element and a second spindle drive arranged between the intermediate element and the external covering engages with the covering elements. The first spindle drive has a first threaded spindle which engages a first spindle nut and is selectively driven in rotation relative thereto by a drive unit. The second spindle drive has a second threaded spindle which engages a second spindle nut that can be driven in rotation relative thereto by the drive unit.
