Abstract
A venetian blind includes a winding drum (5), on which is wound a cord (8) fastened to the lowermost slat (10) of the blind, and a mechanism for orienting the slats of the blind, including a flexible ladder which is driven frictionally and the bands (15, 16) of which are fastened to the slats of the blind for their orientation. The orientation device includes a slide (17) mounted elastically and displaced transversely by the cord (8) when a pulling force is exerted on the cord. The slide controls the passage of stop pieces (27, 28) fixed to the ladders and consequently the orientation of the slats of the blind.
