Abstract

The invention concerns a shade system for a motor vehicle, said system being adapted to obscure a transparent bodywork element. Said shade system comprises at least one shade guideway, a winding shaft and lateral elements wherein are guided the lateral edges of the shade guideway. The lateral edges of the shade guideway have each a flat and flexible driving band. In order to ensure that said diving bands are wound on the winding shaft and are unwound therefrom in a specific manner, a lateral winding guide is arranged at the winding shaft for each driving band, said winding guides preventing the driving bands from being laterally offset at the winding shaft.

Claims

1. A roller blind arrangement for a motor vehicle, comprising at least one roller blind web, a winding shaft and lateral guide rails, in which a respective flexible, flat guide belt with a lateral edge, which is arranged in, and engages a lateral border region of the roller blind web, is guided,

wherein a lateral winding guide for each guide belt is provided externally in the region of the winding shaft and prevents a lateral offset of a relevant guide belt on the winding shaft, the lateral winding guide being transverse to the winding shaft;

and

wherein the winding guides are each formed from a member which is arranged adjacent to an inner edge of the guide belt and medial relative to the web.

2. The roller blind arrangement of claim 1, wherein each respective member is a flexible element.

3. The roller blind arrangement of claim 2, wherein the flexible element is a spring-elastic material.

4. The roller blind arrangement of claim 2, wherein the flexible element is a resilient tab.

5. The roller blind arrangement of claim 1, wherein the lateral winding guides are manufactured integrally with a frame of the roller blind arrangement.

6. The roller blind arrangement of claim 1, wherein the lateral winding guides are each a separate component which is fixed to a frame of the roller blind arrangement.

7. The roller blind arrangement of claim 1, wherein the member is formed from a guide box within which the relevant guide belt is wound up and unwound and which has a curved cutout in which the winding shaft rotates.

8. The roller blind arrangement of claim 7, wherein the guide box is mounted in the radial direction of the winding shaft.

9. The roller blind arrangement of claim 7, wherein the guide box is a separate component which is suspended in a manner to compensate for changes in a diameter of a coil of a roller blind during winding and unwinding.

10. The roller blind arrangement of claim 1, wherein the relevant guide belt on the winding shaft forms a winding body having a plurality of diameters.

11. The roller blind arrangement of claim 10, wherein the plurality of diameters is a function of the amount of an extension of the web.

17. The roller blind arrangement of claim 1, wherein the roller web comprises a pull bow at a first end;

and

at a second end, which faces away from the pull bow, the roller blind web is fixed to a winding tube of the winding shaft.

18. The roller blind arrangement of claim 1, wherein the flat guide belt is guided in a guide track of the lateral guide rails.

19. The roller blind arrangement of claim 18, wherein the guide track is open on an outside with respect to a longitudinal center plane of the vehicle, and

wherein the flat guide belt extends into the guide track of the guide rail by folding of the roller blind web along edges running in an extension direction.

12. A roller blind arrangement for a motor vehicle, comprising at least one roller blind web, a winding shaft and lateral guide rails, in which a respective flexible, flat guide belt with a lateral edge, which is arranged in, and engages a lateral border region of the roller blind web, is guided,

wherein a lateral winding guide for each guide belt is provided externally in the region of the winding shaft and prevents a lateral offset of a relevant guide belt on the winding shaft, the lateral winding guide being transverse to the winding shaft;

wherein the winding guides are each formed from a member which is arranged adjacent to the guide belt and medial relative to the web;

wherein the member is a separate component which compensates for changes in a diameter of a coil of the roller blind during winding and unwinding;

such that the member yields as the winding body of the roller blind web increases in diameter.

13. The roller arrangement of claim 12, wherein the member is arranged adjacent to an inner edge of the guide belt.

14. The roller blind arrangement of claim 12, wherein each respective member is a flexible element.

15. The roller blind arrangement of claim 12, wherein the relevant guide belt on the winding shaft forms a winding body having a plurality of diameters.

16. The roller blind arrangement of claim 15, wherein the plurality of diameters is a function of the amount of an extension of the web.

20. A roller blind arrangement for a motor vehicle, comprising

at least one roller blind web, a winding shaft and lateral guide rails, in which a respective flexible, flat guide belt with a lateral edge, which is arranged in, and engages a lateral border region of the roller blind web, is guided,

wherein a lateral winding guide for each guide belt is provided externally in the region of the winding shaft and prevents a lateral offset of a relevant guide belt on the winding shaft, the lateral winding guide being transverse to the winding shaft;

wherein at least one of the winding guides is formed from a member which is arranged adjacent to the guide belt;

wherein the member is formed from a guide box within which the relevant guide belt is wound up and unwound;

wherein the guide box is configured to compensate for changes in a diameter of a coil of a roller blind during winding and unwinding;

such that the guide box yields further back as the winding body of the roller blind web increases in diameter.
