<p>The roller blind (20) has a casing (2) which encloses a canvas (6) having two edges (8a,8b) and a free edge equipped with a pulling bar (10). The canvas has a first segment (9a) and an inclined second segment (9b) connected at an obtuse angle to one lateral edge (8b). The bar has a part (11) fixed to the first segment and a part (12) pivoted to the fixed part pivoting about an axle (13). The bar pivots between a first position, in which it extends the length of the second segment, and a second position in which it is an extension of the other. A supple cord (14) extending through a guide support (15) has one end fixed to the pulling bar and the other end fixed to the canvas at the top (9c) of the corner connecting to the second segment (9b). A cord tensioning spring (16) pulls down the bar pivoted part along the second segment. <IMAGE></p> |
