ABSTRACT:
A windup window shade is provided with windup window shade mechanism which, in the extracted state, make possible different degrees of opacity at the window. To this end, the two window shade web can either be wound on separate windup shafts and spread out in the same direction from the same starting point, or the two window shade webs have been connected with each other and, after having been extended, are moved in the manner of a film in front of the window. Two windup shafts are employed in both cases, wherein in the one case the two windup shafts are located directly next to each other, while in the other case the windup shafts are separated from each other during the extension of the shade.
