An electrically adjustable steering column as it is used in motor vehicles. The present invention pertains, in particular, to a steering column that has at least two adjusting units, which are arranged on an adjusting spindle and can be moved in the axial direction of the adjusting spindle. The steering column comprises according to the present invention:a mounting plate (9),a steering column jacket (6) with a steering wheel connection (12),an electrically driven adjusting device for the longitudinal adjustment and the tilt adjustment of the steering column (2), wherein the adjusting device comprises:an electric drive unit (1) for rotatingly driving a one-part adjusting spindle (2),two adjusting units (3 and 4, respectively), which are arranged on the adjusting spindle (2) and can be moved in the axial direction of the adjusting spindle (2),wherein the first adjusting unit (4) is pivotably connected with the mounting plate via a pivoted lever (7) such that the axial movement of the adjusting unit (4) is mechanically transmitted [sic—converted—Tr.Ed.] into a tilting movement of the steering column jacket (6), and the second adjusting unit (3) is connected with the mounting plate via a fastening element (8) such that the axial movement of the first adjusting unit (3) is mechanically transmitted [sic—converted—Tr.Ed.] into a longitudinal movement of the steering column jacket (6), wherein one of the two adjusting units (3 and 4, respectively) is in permanent functional connection with the adjusting spindle (2) and is moved in the axial direction during the rotation of the adjusting spindle (2) and the other of the two adjusting units (4 and 3, respectively) can be brought into functional connection with the adjusting spindle (2) only by activating a switching device (5).
