Abstract
An adjustment drive for a steering column for a motor vehicle comprises a threaded spindle which extends axially in the direction of a spindle axis and engages in a spindle nut, and a drive unit by which the threaded spindle and the spindle nut are driveable in rotation relative to one another, wherein the drive unit has a gear mechanism comprising a worm screw which is driveable in rotation about a worm axis standing transversely to the spindle axis, and a worm thread of the worm screw engages in the toothing of a gearwheel coaxially connected to the threaded spindle or the spindle nut, wherein a thread tooth of the worm thread engages in a tooth gap between two adjacent teeth of the toothing of the gear wheel, wherein a blocking device is provided which can be brought into a blocking position for fixing the threaded spindle relative to the spindle nut, and wherein the gearwheel and the worm screw are displaceable relative to one another in the direction of the spindle axis, and the toothing and the worm thread are configured to convert a relative axial displacement into a reduction of the gear play between gearwheel and worm screw.
