ABSTRACT:
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 light therebetween. The cells can be arrayed in either vertical or horizontal orientations. Another embodiment employs flexible vanes in place of collapsible cells.
