Abstract

A windup window shade for motor vehicles has a rotatably seated windup shaft, on which a window shade web is fastened by an edge. The other edge is fastened on a traction rod, whose ends are guided in guide rails. The distance between the guide rails changes very greatly, viewed in the direction of movement of the window shade web, because of which the length of the traction rod can be changed in a telescope-like manner. It is composed of a center element and two end elements, wherein it is provided with the aid of a centering device that the center element always remains centered in respect to the end elements.
