The vent arrangement is formed with a defroster nozzle connected to an air distributor housing. A defroster nozzle is provided with a wall web dividing the defroster nozzle into air guiding ducts of unequal cross-sectional areas and the air distributor housing is provided with an adjustable covering device providing for a selectively independent regulation of the flow of the defroster air into the air distributor housing and through to the windshield.
