Device for stowing a steering column
The steering column having a lug, a casing, an inner tube, an outer tube, a steering wheel end-piece, and at least one adjustment gear motor. The lug is axially movable and the column includes a gear motor controlling the lug. Having a movable lug makes it possible to increase the stowing length of the steering wheel. The range of movement is the sum of the movements of the lug and the adjustment gear motor.
1. A steering column comprising a leg, a fairing, an inner tube, an outer tube, a steering wheel stub and a first axial adjustment geared motor unit, wherein the leg is axially mobile and the column comprises a second axial adjustment geared motor unit operating the leg.
2. The steering column as claimed in claim 1 , wherein the outer tube is axially mobile and the first axial adjustment geared motor unit operates said outer tube.
3. The steering column as claimed in claim 1 , wherein the column can be inclined and wherein a vertical adjustment geared motor unit controls the rake of said column.
4. The steering column as claimed in claim 1 , wherein a control device actuates the axial adjustment geared motor units.
5. The steering column as claimed in claim 4 , wherein the control device actuates all the geared motor units at the same time.
6. The steering column as claimed in claim 1 , wherein the outer tube slides on the inner tube.
7. The steering column as claimed in claim 6 , wherein the sliding of the outer tube on the inner tube takes place using a bushing.
8. The steering column as claimed in claim 1 , wherein the leg slides inside the fairing by means of a guide system made up of rails and of balls.
9. The steering column as claimed in claim 8 , wherein the leg slides inside the fairing by friction.
10. The steering column as claimed in claim 1 , wherein the first axial adjustment geared motor unit is connected to the outer tube by a threaded screw.
11. The steering column as claimed in claim 1 , wherein the first axial adjustment geared motor unit is fixed to the leg.
12. The steering column as claimed in claim 1 , wherein the first axial adjustment geared motor unit is fixed to the outer tube.
13. The steering column as claimed in claim 1 , wherein the second axial adjustment geared motor unit is fixed to the fairing.
14. The steering column as claimed in claim 1 , wherein the second axial adjustment geared motor unit is fixed to the leg.
15. The steering column as claimed in claim 1 , wherein the leg slides in the fairing with an angle with respect to the movement of the outer tube.
16. The steering column as claimed in claim 1 , wherein the leg slides in the fairing parallel to the movement of the outer tube.
17. A steering column comprising a leg, a fairing, an inner tube, an outer tube, a steering wheel stub and one axial adjustment geared motor unit and one vertical adjustment geared motor unit, wherein the leg is axially mobile and the column comprises a second axial adjustment geared motor unit operating the leg.
