Abstract

The invention concerns a shade system (10,40,50) for a motor vehicle, said system being adapted to obscure a transparent bodywork element. Said shade system comprises at least one shade guideway (12), a winding shaft and lateral guide elements (18, 20) wherein are guided the lateral edges of the shade guideway (12). The lateral edges of the shade guideway (12) have each a flat and flexible driving band (22A, 22B). In order to ensure that said driving bands (22A, 22b) are wound on the winding shaft (16) and are unwound therefrom in specific manner, a lateral winding guide (28A, 28B;42;52) is arranged at the winding shaft (16) for each driving band (22A, 22B), said winding guides (28A, 28B;42;52) preventing the driving bands (22A, 22B) 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, which is arranged in a lateral border region of the roller blind web, is guided, characterized in that a lateral winding guide for each guide belt is provided in the region of the winding shaft and prevents a lateral offset of the relevant guide belt on the winding shaft.

2. The roller blind arrangement of claim 1, characterized in that the winding guides are each formed from a flexible element which is arranged on that side of the guide belt which faces away from the relevant roller blind web border.

3. The roller blind arrangement of claim 2, characterized in that the flexible element is manufactured from a spring-elastic tool.

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

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

6. The roller blind arrangement of claim 1, characterized in that 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, characterized in that the lateral winding guides are each 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, characterized in that the guide box is mounted resiliently in the radial direction of the winding shaft.
