ABSTRACT:
A roller shade comprising a spring-loaded retractor, a screen sheet having a trailing edge connected to the retractor, and a rod member attached to a leading edge of the screen sheet. The two ends of the rod member are guided by a pair of guide rails so that the rod member may be moved toward and away from the retractor by using a power drive unit in such a manner that the screen sheet may be paid out from the retractor and extended against the spring force acting on the retractor, and retracted or wound around the retractor, as desired. The rod member incorporates therein a telescopic structure which allows its length to be varied according to the change in the distance between the guide rails as the rod member is moved toward and away from the retractor. Thus, the roller shade can be adapted to windshields, windows or other openings having trapezoidal, curved or other non-rectangular shapes.
