CA 2242637

A window covering comprises spaced collapsible cells secured to a pair of control cords which may be actuated to cause the cells to expand or contract their cross- sectional shape. In their collapsed and partially expanded conditions, the cells are spaced from each other to permit a variable amount of light to pass therebetween, while in their fully expanded condition the cells preferably contact and overlap each other to completely block passage of ligth therebetween. The cells can be arrayed in either vertical or horizontal orientations. Another embodiment employs flexible vanes in place of collapsible cells.

Un couvre-fenêtre comporte des cellules, distinctes, repliables et rattachées à deux cordons de commande. Il est possible de manoeuvrer ces cordons pour faire se déployer ou se resserrer les cellules sur leur partie transversale. En position repliée et partiellement déployée, les cellules sont séparées les unes des autres afin de laisser passer entre elles un flot variable de lumière alors que, lorsqu'elles sont complètement déployées, ces cellules entrent, de préférence, en contact l'une avec l'autre et se chevauchent de manière à empêcher tout passage de lumière. Ces cellules peuvent être disposées en rangées, que ce soit verticalement ou horizontalement. Dans un autre mode de réalisation, on met en oeuvre des volets mobiles à la place des cellules repliables.
