Title: MOTOR-ADJUSTABLE STEERING COLUMN FOR A MOTOR VEHICLE
Abstract:
The invention relates to a motor-adjustable steering column (1) for a motor vehicle, comprising a supporting unit (2) that can be connected to the vehicle body, by which an actuator unit (3) is held, which comprises a steering spindle (5) mounted in a casing unit (4) such that the steering spindle (5) can be rotated about a longitudinal axis (31), wherein the casing unit (4) has an outer casing tube (41), in which an inner casing tube (43) is telescopically axially displaceably mounted, and having an actuating drive (6) which is connected to the inner (43) and the outer casing tube (41) and by which the inner casing tube (43) can be moved axially in and out relative to the outer casing tube (41). The problem addressed by the invention is that of permitting an improved ability to be stowed as a result of compact dimensions in the retracted state. This problem is solved in that, coaxially between the outer casing tube (41) and the inner casing tube (43), there is arranged at least one intermediate casing tube (42), which is telescopically axially displaceably mounted with low friction in the outer casing tube (41) and in which the inner casing tube (43) is telescopically axially displaceably mounted with low friction, and which can be moved in and out axially by the actuating drive (6) relative to the inner and outer casing tube.
