Abstract: A roller blind (10) with a curtain that can be wound up on a winding shaft and can be unwound against a spring tension, with a spring (31) for generating the spring tension. The spring (31) is configured such that the curtain remains in each unwound position in a self-retaining manner. A manufacturing effort can be reduced during the assembly by the spring drive being assembled from one or more modularly connected, prefabricated partial springs (31).

Abstract: An actuating device has a string element (16) for actuating a shading system (10), which string element is guided at least with one half loop (19) within an actuating device section (15) of the actuating device (11), with a gripping element (17) guided displaceably at the actuating device section in the longitudinal direction of the section. The gripping element has an actuating element (29, 30), which can be reached and operated with a thumb, for detachably connecting the gripping element with the string element. The actuating element is mounted pivotably at the gripping element. The actuating element has a mount (31) for receiving a section of the string element on a side facing the string element. The mount is U-shaped or C-shaped for partially enclosing the string element and/or for extending behind a string member (26) of the string element.
