ABSTRACT:
A system for ventilating the passenger compartment of an automotive vehicle comprises an air discharge nozzle located at approximately the center of the vehicle's dashboard along a lower edge of the windshield. The nozzle ejects a broad air stream upwardly along an inner surface of the windshield. The air stream is received by a funnel located along the upper edge of the windshield between the windshield and the rearview mirror. The interior of the funnel communicates with an interspace defined by the vehicle roof and a roof lining. The interspace is closed along the rear window and is provided with air deflection elements for steering a portion of the inflowing air stream laterally towards the sides of the vehicle. The roof lining is provided above the passenger seats with a multiplicity of openings having adjustable cross-sectional areas for varying the amount of air entering the passenger compartment through the openings. Directional louvers or grids are also provided for varying the direction of air flow through the roof lining openings into the passenger compartment. The roof interspace decreases in width towards the rear end of the vehicle, while lateral slots are formed in the roof lining along the side windows of the vehicle.
