Abstract
Abstract Apparatus for preventing dust from settling on or being blown against a rear window of a vehicle has strip members arranged horizontally across the rear window. Each strip member defines a plane. The planes intersect substantially in a line at a rear view mirror in the vehicle so as to permit a rear view from the mirror through the rear window which is substantially unimpeded by the strip members. The strip members are additionally assembled on a frame which is detachably supported on the vehicle for removal when the vehicle passes through a washing or other device which may damage the strips and for ease in such occasional washing of the rear window as may be required even with use of the apparatus.
