Problems solved by technology

However, the known steering column has the disadvantage that either it cannot be retracted far enough for stowing purposes, or it has a relatively large dimension in the longitudinal direction in the retracted state in order to achieve a sufficient adjustment travel

Embodiment Construction

[0040] In the individual figures, identical components are always provided with the same reference numerals and are therefore usually also designated or mentioned only once in each case.

[0041] figure 1 , figure 2 and image 3 The steering column 1 according to the invention is shown obliquely from above in a schematic perspective view of the rear end with respect to the direction of travel of the vehicle (not shown). figure 2 shows the fully retracted state, figure 1 Shown from the left ( figure 1 ) the observed (partially) stretched state and image 3 Shown from the right ( image 3 ) observed (partially) extended state.

[0042] The steering column 1 comprises a bearing unit 2 comprising fastening means 21 for connection to a motor vehicle body (not shown). The bearing unit 2 holds an adjustment unit 3 comprising a sleeve unit 4 in which a steering spindle 5 is mounted rotatably about a longitudinal axis 31 of the adjustment unit 3 . On the rear end with respect...

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 bywhich 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 stowedas 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.

Description

technical field [0001] The invention relates to a motor-adjustable steering column for a motor vehicle, the steering column comprising a bearing unit connectable to the body and holding an adjustment unit, the adjustment unit comprising a steering spindle in a sleeve unit is mounted to be rotatable about a longitudinal axis, wherein the bushing unit includes an outer bushing in which the inner bushing is telescopically accommodated to be axially displaceable, and the steering column includes a linear adjustment drive , the linear adjustment drive is connected to the inner sleeve and the outer sleeve, and wherein the inner sleeve can be axially retracted and extended relative to the outer sleeve. Background technique [0002] A steering column for a motor vehicle comprises a steering shaft with a steering spindle, on the rear end of the steering spindle in the direction of travel, ie on the end facing the driver, a steering wheel is mounted for responding to the driver's stee...
