Abstract
A roller-blind shaft for a protective apparatus in a vehicle interior on which at least one flexible flat structure is held such that it can be wound up and unwound, the roller-blind shaft having a curved bearing axle and sleeve-like roller-blind shaft sections which are mounted rotatably on the bearing axle and are connected axially to one another to form a rotationally locked unit. In each case at least one axially inserted and axially secured sliding ring is provided for each roller-blind shaft section for mounting the roller-blind shaft sections on the bearing axle, which sliding ring mounts the roller-blind shaft section in a contactless manner at a radial spacing from the bearing axle.
Claims19
A roller-blind shaft assembly for a protective apparatus in a vehicle interior, said assembly comprising:
- a curved bearing axle;
- a plurality of roller-blind shaft sleeve sections non-rotatably and axially connected to one another to form a unitary roller-blind shaft, said roller-blind shaft windably mounting thereon a flexible sheet structure;
- and
- a plurality of rings provided on said bearing axle, each said ring mounting one of said roller-blind shaft sleeve sections on said bearing axle for rotation relative thereto, each said ring being disposed radially between said bearing axle and the respective said roller-blind shaft sleeve section to maintain the respective said roller-blind shaft sleeve section radially spaced from, and not in contact with, said bearing axle, wherein movement of each said ring relative to the respective said roller-blind shaft sleeve section is prevented in at least one axial direction by a protrusion and each said ring is slidably movable relative to one of said bearing axle or the respective said roller-blind shaft sleeve section.
A roller-blind shaft assembly for a shading apparatus for a vehicle interior, said assembly comprising:
- an elongate and curved bearing axle;
- a plurality of roller-blind shaft sleeve sections non-rotatably connected to one another in an end-to-end manner in an axial direction to form an elongate roller-blind shaft;
- a plurality of rings disposed in an axially spaced-apart manner with one another along said bearing axle, with each said ring mounting one of said roller-blind shaft sleeve sections on said bearing axle for rotation relative thereto, each said ring being disposed radially between said bearing axle and said one roller-blind shaft sleeve section to maintain said one roller-blind shaft sleeve section in a radially-spaced manner from said bearing axle;
- and
- a securing arrangement associated with each of said roller-blind shaft sleeve sections, each said securing arrangement including a protrusion disposed to prevent movement of one of said rings in one axial direction relative to the respective said roller-blind shaft sleeve section.
