Abstract
A quiet drive device for motor vehicle sliding sunroofs is proposed capable of withstanding even strong drive forces and permitting an equal, that is to say, smooth displacement of a cover of the motor vehicle sliding sunroofs. The drive device comprises a toothed belt, which is guided so that two parallel line sections are formed on the toothed belt. On the running line sections the toothed belt, with an external toothing extending without interruption over its outer circumference, is in meshing engagement with two drive cables for a cover. An internal toothing extending without interruption over the inner surface of the toothed belt is in meshing engagement with a toothed pinion that can be driven to rotate in both directions and is partially wrapped by the toothed belt.
