Abstract
Abstract An air flow device for positioning in the rear windows of closed motor vehicles and boats. The device has a frame which fits within the window or an unclosed portion of the window. Means are provided for attaching the device frame to the window frame. A transparent plate is attached at its bottom to the bottom portion of the device frame on its side inside of the motor vehicle. The transparent plate is positioned at its top away from the top of the device frame (or the vertical plane of the window). A gap exists between the top of the device frame and the top of the plate. There are two side members, each of which is attached to a set of corresponding ends of the device frame and the plate. The side members prevent lateral air flow into the motor vehicle.
