Abstract
A roller blind arrangement for a motor vehicle, having a roller blind web and a winding shaft onto which the roller blind web can be wound and from which the roller blind web can be unwound and which has a flexible hollow tube arrangement penetrated by a bearing beam attached to the vehicle. The hollow tube arrangement may have a hollow tube element which, viewed in the axial direction, may have multiple flexible portions interrupted by at least one stabilizing portion having a greater torsional strength than the flexible portions.
Claims8
A roller blind arrangement for a motor vehicle, the roller blind arrangement comprising:
- a roller blind web and
- a winding shaft onto which the roller blind web can be wound and from which the roller blind web can be unwound and which comprises a flexible hollow tube arrangement penetrated by a bearing beam attached to the vehicle,
- wherein the hollow tube arrangement comprises a hollow tube element which, viewed in the axial direction, comprises multiple flexible portions interrupted by at least one stabilizing portion which provides greater torsional strength than the flexible portions;
- wherein the at least one stabilizing portion of the hollow tube element comprises a plastic overmolded base tube,
- wherein the base tube is a corrugated tube and its plastic overmold forms a circumferential surface whose radius is equal to a maximum outer radius of the corrugated tube,
- wherein the plastic overmold is formed on the corrugated tube in an annular shape and disposed in spaces between ribs of the corrugated tube, and
- wherein the at least one stabilizing portion comprises at least two stabilizing portion ribs and two spaces between the at least two stabilizing portion ribs.
