Title: MOTOR-ADJUSTABLE STEERING COLUMN FOR A MOTOR VEHICLE
Abstract:
The invention relates to a motor-adjustable steering column (1) for a motor vehicle, having a mounting unit (2), which can be attached on a vehicle body, and on which an adjuster unit (3) is mounted in which a steering spindle (32) is mounted for rotation around a longitudinal axis (L), and having an actuator (5), which is connected to the mounting unit (2) and the adjuster unit (3), and by means of which the adjuster unit (3) can be adjusted relative to the mounting unit (2), wherein the actuator (5) comprises a drive unit (55) and a lead screw (52) engaging in a spindle nut (51) and having a lead screw axis (G), wherein the lead screw (52) and the spindle nut (51) can be driven by the drive unit (55) to rotate relative to each other around the lead screw axis (G). To prevent, as far as possible, slipping 5 or spinning of the spindle drive in the event of a crash, according to the invention the actuator (5) comprises a blocking device (7) which can be brought into a blocking position to block the lead screw (52) relative to the spindle nut (51).
