Abstract: An air-actuated curtain device for covering the windshield and windows of a vehicle for the purpose of blocking the rays of the sun. The device activates the spring loaded roll-on curtains through compressed air that is forced through a distensible element that is perpendicularly positioned on the curtain sheets with respect to their respective mandrels. The air compressor is controlled by a timer, or a pressure switch, that permits to operate a sufficient amount of time, or reach a predetermined pressure limit, to fully distend the curtain sheets. Upon release of the pressurized air, the curtain sheets come back to their initialed rolled state. Air pressure release valves are used to manually and automatically release the air in the conduits when it exceeds a given pressure.
