Abstract
Abstract The vehicle window ventilator is of a one-piece construction, including a top bulbous portion and a bottom polyurethane portion having openings extending therethrough angled from the interior of the vehicle rearwardly to the exterior for inducing quiet air flow out of the passenger compartment. Pressure of the upper edge of the window against the bottom portion of the ventilator controls the opening and closing of the polyurethane openings. The bulbous upper portion is suitable for being mounted in the inverted window channel of any vehicle window without the use of screws or hardware.
