Abstract: A protective device including a flexible fabric shiftable longitudinally between different functional positions, and provided on opposite side edges with respective stiffening strips guided in a manner shiftable longitudinally in vehicle-mounted guide tracks. A pull-out profile extends transversely with respect to the longitudinal shifting direction of the fabric and is connected to an end region thereof. The pull-out profile is guided in the vehicle-mounted guide tracks by guide elements, and each stiffening strip is fastened on the end side to a respective guide element. Each stiffening strip has at least three receptacles provided one behind another in the longitudinal shifting direction, and the guide element is assigned at least three profiling portions spaced apart from one another in the longitudinal shifting direction and projecting into the receptacles in a form-fitting manner transversely with respect to the longitudinal shifting direction.

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.

Abstract: The invention relates to a method for attaching guide means (106) to a flexible sheet (100), preferably as part of a shading system for a vehicle, and to a device provided therefor. Holding regions (102a, 102b), spaced apart from one another in a Y-direction, of a flexible sheet (100) extending in an X-direction and a Y-direction are spaced apart from one another by being acted upon with a predetermined pretensioning force (Fv) acting in the Y-direction, with the result that a pretension state is achieved. Subsequently, in a further processing state which corresponds to the pretension state or to a pretension state relieved by the amount of a predetermined relief distance (S3) in the Y-direction with respect to the pretension state, guide means (106) extending parallel to one another in the X-direction and spaced apart from one another in the Y-direction are fastened to the sheet (100).
