Abstract: A vehicle has a roof assembly (4) opening an opening (17) in the vehicle roof which includes at least a rear cross beam (12). The roof assembly comprises at least one closure element (8,9,10) which is at least one closure element (8,9,10) which is at least movable between a closed position for closing the roof opening, and an open, rearwardly displaced position, in which the roof opening is at least partially released. The rear cross beam (12) is connected to pivotable arms (13) which are at least pivotally attached to the body (1). The at least one closure element (8,9,10), when in the open position, forms a unit (15) with said rear cross beam (12). The unit (15) is pivotable by means of said arms (13) between an operative position at the roof and an inoperative position in the trunk (3) of the vehicle.
