Each draw-out arm (4,4a) has at least two rod parts, which are joined to one another by an elastic component (12), in order to form an intended bending position of the draw-out arms with predeterminable spring rigidity. A defined elastic binding movement of the draw-out arms is achievable vertically to the draw-out direction of the roller blind sheet. The distance of the tractive strip (5) to the winding shaft (3) is variable by draw-out arms (4,4a), which at least at their one end section are fitted pivotably on a roller blind cassette (18) locating the winding shaft or on the tractive strip (5).
