Automatically opening cargo compartment cover

A cargo compartment cover for closing off an upper access opening of a cargo bay of a motor vehicle having a rear opening comprising:

• a rotatably supported winding shaft;
• a cover sheet having a first end fastened to the winding shaft, the cover shaft being movable between an open position wherein maximum access is allowed through the upper access opening of the cargo bay, a closed position wherein a top of the cargo bay is completely closed off, and an intermediate position wherein the top of the cargo bay is partially open;
• a pullout bar that is fastened to a second end of the cover sheet, remote from the winding shaft;
• two guide rail arrangements that extend along a path that the pullout bar follows when the cover sheet is moved into the intermediate position starting from the closed position;
• two linear actuating members each of which runs in a respective one of the guide rail arrangements;
• positively engaging stops for limiting the travel of actuating members;
• two coupling members for positively coupling a respective actuating member to one end of the pullout bar at least relative to one direction of movement;
• two gear motors, each operating at the same nominal speed and each having a permanently excited DC motor;
• and
• wherein the two gear motors operate completely independently of one another mechanically and electrically, and the arrangement is free of devices for electrically synchronizing gear motors with one another during their operation.
