Abstract: An open roof construction or assembly for a vehicle having an opening in its fixed roof comprises a stationary part to be fixed to the roof. An upper closure element supported by said stationary part is adjustable between a closed position, in which it closes the roof opening, and an open position, in which it releases the roof opening at least partially.

Abstract: A folding roof for a vehicle having an opening in its fixed roof comprises a frame to be mounted in the opening, which frame comprises a passage opening and a flexible cover for selectively closing or releasing the opening. A control beam which is attached to the opening side of the cover, is guided in guide rails at its lateral ends. A driving mechanism is connected to the control beam and selectively moves the control beam for opening or closing the folding roof. A push-off element can come into engagement with the frame when the control beam approaches the closed position. A transmission mechanism positioned between the push-off element and the drive mechanism pulls the control beam to the closed position with increased driving force during the last part of the closing movement. The push-off element is provided laterally of the control beam and co-operates with the stationary guide rails.
