Device for guiding an air flow in the region of a roof opening

The device for the directing of the airflow in the region of a roof aperture in a vehicle includes a wind deflector (5) to which is movably fastened an additional wind deflector (7). In its non-extended position the additional wind deflector is attached to the underside of the first deflector, and with its movement into the extended position moves along on the rear end face of the first wind deflector. A cover is provided to close off the roof aperture, and the first wind deflector and cover lie one behind the other when the roof is closed.
