Abstract
A height-adjustable steering column for motor vehicles which is retractable and extendible by means of a drive motor, comprises an inner steering spindle assembly of axially telescoping parts, of which an upper one is connected with the steering wheel, as well as a jacket tube in which an axially displaceable part of the steering spindle assembly is rotatable and is arranged axially displaceable in a housing inside the jacket tube. A coupling member drivable by the drive motor is axially non-displaceable relative to the housing and has a drive pinion which engages in a serration on the circumference of the jacket tube.
