A roll-up window shade for motor vehicle windows is provided that has guide rails running at the side of the extended shade element. A linear push element is provided for each guide rail. Each push element is driven by a separate gear. Therefore, complicated guide tubes, which among other problems generate a lot of friction, are eliminated. A trunk cover has a guide rail on each side of the shade element. For driving the shade element, a push element is provided for each guide rail. The push element is constructed as a non-endless drive element. Each push element is driven by a separate motor and a separate gear. Electrical synchronization of the motors is not provided.
