Abstract: An air flow device (replacement window) for motor vehicles or boats with a rear window. The window includes a frame which is adapted to fit in the rear aperture. The window frame has four frame members, top, bottom, and two sides forming a window opening. Optimally at least one pane member is positioned within the window frame as to block a portion of the window opening. The edge of the window frame that contacts the window frame is vertical. The device when positioned in the window frame includes a transparent plate in the central region. Attaching the air flow device to the window frame's bottom includes a pivoted portion of the plate to the bottom window frame's member. There are two vertical side members. Each side is attached to one of the vertical members, and the other side is attached to one end of the plate. Each side member is pleated in the vertical direction. The pleats decrease in width in the vertical direction to form a point at the lower edge while the upper vertical member's edge is straight.

Abstract: An air flow device for a closed motor vehicle or boat for positioning in the rear aperture thereof which includes structure for attaching the air flow device to the rear aperture. There is a plate which is transparent in at least the central region thereof. The attachment structure, which includes a pivot means, is pivotally attached to the bottom portion of the plate and to the lower rim of the aperture. There are two vertical side members, each of which is attached to an end of the plate so as to extend outwardly from the plate. Each of the vertical side members is in sliding relationship with one of the vertical sides of the rear aperture and/or of window glass mounted therein. There are two narrow end members, each of which is attached to an unoccupied end of one of the vertical side members and extends away from the plate. When the plate is in an upright position so as to close the rear aperture, the vertical side members extend outwardly from the rear aperture of the vehicle.

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.
