Abstract: A winding shaft unit for receiving a roller blind sheet in a wound-up condition, wherein the winding shaft unit has a winding tube extending in the direction of a rotation axis and the winding shaft unit has at least one bearing bush inserted into the winding tube, the bush being a terminal closure of the winding tube, wherein the bearing bush has, on a circumferential exterior surface, a contact zone for resting on an interior surface of the winding tube and has, on a circumferential interior surface, a bearing zone for cooperation with a bearing pin. The bearing bush is made partially of a first material and partially of a second material differing from the first material.

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.
