Abstract
An adjusting drive for a motor-adjustable steering column may include an outer threaded spindle that has an external thread that engages with a spindle nut and that has an internal thread that is engaged by an inner threaded spindle. The spindle nut, the outer threaded spindle, and the inner threaded spindle can be driven in rotation relative to one another about an axis by a motor-type drive unit. The adjusting drive may also include a blocking device that is switchable between a first position and a second position. In the first position the outer threaded spindle is locked together with the spindle nut for conjoint rotation. In the second position the outer threaded spindle is locked together with the inner threaded spindle for conjoint rotation.
