ABSTRACT:
A motor-vehicle window curtain is fastened to gliders which are longitudinally displaceable along upper and lower profile rails by means of two displacement wires which extend through the gliders. For opening and closing the curtain, the displacement wires are wound on and off in separate conically formed winding grooves which are arranged coaxially with one another on a motor-driven rotor. The ratio of the radii of the winding grooves is equal to the ratio of the necessary displacement lengths of the respective wires so that synchronous displacement of the curtain along the upper and lower rails is ensured and jamming is avoided.
