Abstract

A shading device of a water vehicle, having a roller blind web, a winding unit, onto which the roller blind web can be wound or unwound and which, in relation to a longitudinal center plane of the roller blind web, is borne on both sides so as to be rotatable, and comprising, in relation to the longitudinal center plane of the roller blind web on each of its two sides, a telescopic tube arrangement having a bearing tube that is fixed relative to the vehicle and having at least one first pull-out tube and one second pull-out tube, which are displaceable between a slid-in position, the roller blind web having been wound up onto the winding unit when being in said position, and a pulled-out position, the roller blind web having been unwound from the winding unit when being in said position.

First claim

The invention claimed is:

1. A shading device of a vehicle, comprising a roller blind web, a winding unit, onto which the roller blind web can be wound up or from which the roller blind web can be unwound and which, in relation to a longitudinal center plane of the roller blind web, is borne on both sides so as to be rotatable, and comprising, in relation to the longitudinal center plane of the roller blind web on each of its two sides, a telescopic tube arrangement having a bearing tube that is fixed relative to the vehicle and having at least one first pull-out tube and one second pull-out tube, which are displaceable between a slid-in position, the roller blind web having been wound up onto the winding unit when being in said position, and a pulled-out position, the roller blind web having been unwound from the winding unit when being in said position, wherein at least one of the telescopic tube arrangements is provided with a drive unit, which directly drives the first pull-out tube, a rope arrangement converting a relative movement of the first pull-out tube vis-a-vis the bearing tube into a relative movement of the second pull-out tube vis-a-vis the first pull-out tube.

2. The shading device according to claim 1 , wherein the drive unit comprises a spring unit which takes effect in the pull-out direction, and which pretensions the respective first pull-out tube in the pull-out direction, and in that the winding unit is provided with a self-locking actuating unit, whose holding force is greater in the unactuated state than the effective spring force of the spring unit.

3. The shading device according to claim 2 , wherein the spring unit comprises a gas pressure spring.

4. The shading device according to claim 1 , wherein the drive unit comprises an electric motor.

5. The shading device according to claim 4 , wherein the electric motor drives a threaded spindle, which engages with a screw thread, which is arranged at the respective first pull-out tube, or in that the motor drives a drive cable which is rigid in compression, and which is fastened to the first pull-out tube.

6. The shading device according to claim 1 , wherein the rope arrangement comprises a rope, which is fastened to the second pull-out tube and is guided via at least one deflection unit, which is arranged at the first pull-out tube.

7. The shading device according to claim 6 , wherein the deflection unit is a pulley.

8. The shading device according to claim 1 , wherein the winding unit is provided with a drive motor.

9. The shading device according to claim 8 , wherein the drive motor drives the winding unit via a gearing.

10. The shading device according to claim 8 , wherein the winding unit comprises a winding tube and in that the drive motor is a tubular motor, which engages the winding tube.

11. The shading device according to claim 1 , wherein the roller blind web, with its edge facing away from the winding unit, is joined to a transverse strut, which connects the second pull-out tubes of the two telescopic tube arrangements to one another.

12. The shading device according to claim 1 , wherein the two first pull-out tubes of the telescopic tube arrangements are connected to each other via a transverse strut, the roller blind web reaching over said strut.

13. A shading device of a vehicle, comprising a roller blind web, a winding unit, onto which the roller blind web can be wound up or from which the roller blind web can be unwound and which, in relation to a longitudinal center plane of the roller blind web, is borne so as to be rotatable on both sides, and comprising, in relation to the longitudinal center plane of the roller blind web on each of its two sides, a telescopic tube arrangement having a bearing tube that is fixed relative to the vehicle and having at least one pull-out tube, which is displaceable between a slid-in position, the roller blind web having been wound up onto the winding unit when being in said position, and a pulled-out position, the roller blind web having been unwound from the winding unit when being in said position, wherein the winding unit, as its drive, includes at least one electric motor and the telescopic tube arrangements are pretensioned in the direction of their pull-out position with the aid of a spring unit.

14. The shading device according to claim 13 , wherein the electric motor drives the winding unit via a worm gearing.

15. The shading device according to claim 14 , wherein between the worm gearing and the winding unit, a drive belt is arranged, engaging with a drive wheel, which is connected to the winding unit for co-rotation.

16. The shading device according to claim 13 , wherein the winding unit, on each of its two sides, is driven by an electric motor.

17. The shading device according to claim 13 , wherein the electric motor is a tubular motor, which engages a winding tube of the winding unit.

18. The shading device according to claim 13 , wherein the winding unit comprises a curved flexible winding tube, which reaches around a curved bearing bow.

19. The shading device according to claim 13 , wherein each of the telescopic tube arrangements comprises at least one first pull-out tube and one second pull-out tube and wherein at least one of the telescopic tube arrangements is provided with a drive unit, which directly drives the first pull-out tube, and in that a rope arrangement converts a relative movement of the first pull-out tube vis-a-vis the bearing tube into a relative movement of the second pull-out tube vis-a-vis the first pull-out tube.

20. The shading device according to claim 19 , wherein the rope arrangement comprises a rope, which is fastened to the second pull-out tube and is guided via at least one deflection unit, which is arranged at the first pull-out tube.

21. The shading device according to claim 20 , wherein the deflection unit is a pulley.

22. The shading device according to claim 13 , wherein a holding force is applied onto the winding unit in the unactuated state, the holding force being greater than the effective spring force of the spring unit.
