Abstract
An adjustable steering column for a steer-by-wire steering device may include an actuating unit that comprises a steering spindle mounted rotatably about a longitudinal axis in a casing unit. The casing unit may have a first casing tube in which a second casing tube is arranged in a rotationally fixed manner with respect to the longitudinal axis and is mounted so as to be movable axially in a telescopic fashion. An actuating drive is connected to the first casing tube and the second casing tube and can move the second casing tube relative to the first casing tube. The actuating drive may comprise a spindle drive with a threaded spindle that is parallel to the longitudinal axis, rotatably drivable by a servomotor, supported on and extending within the first casing tube, and screwed into a spindle nut attached in a rotationally fixed manner to the second casing tube.
