  • Deflector for directing downwards a flow of air along the surface of the rear window of a car
    Patent number: 4726618
    Abstract: Deflector apparatus for directing a flow of air downwards along the rear window of a car comprises a curved, elongated deflector plate (5) that is positioned substantially parallel to the rear window with the upper edge of the deflector plate being just above the roof-line (2) of the car and being mounted on the car by means of at least one mounting member. In order to avoid having the mounting members interfere with opening of the rear door (1) of the car and to eliminate the need for drilling of holes in the metal parts of the car, the mounting member (6) is fastened to the glass of the rear window itself, preferably by gluing, so that, without touching the painted metal parts of the car, the deflector plate, will extend above the metal parts of the car and above the rear window (4).
