Abstract (en)
[origin: EP0322354A1] The lamellar blind (7) has a connection between the draw members (15) in the lateral guides (1) and the carriage (33) arranged at the lower end of the link chain (37), which is releasable in the event of the appearance of an obstacle (50) in the movement path of the slats (5). After removal of the obstacle (50), the carriage (33) engages on the draw member (15) again, either by its own weight or by pulling up the draw member (15). On encountering the obstacle (50) before the release of the abovementioned connection, a spring (13) between the drive wheel (11) and the drive shaft (9) creates a successively increasing resistance on the drive crank and makes possible in the lowest position of the blind (7) first the opening of the slats (5) before the vertical movement "up". <IMAGE>
