ABSTRACT:
In a rear view mirror for a motor vehicle with a housing connected with an air source, traversed by air guide channels, and holding a mirror glass, with the outlets of the channels being arranged along the edge of the mirror glass to allow air to escape opposite to the direction of forward travel of the vehicle, modified guidance and processing of the escaping air reduces the danger of contamination of the mirror glass by the wind blast as well contamination of the side window associated with the mirror. This is also intended to improve the flow resistance of the mirror as well as its noise behavior. For this purpose, a plurality of separate air channel outlets is provided that are located within a guiding device and/or are equipped with one that produces vorticized air streams that emerge and are stable at each of the air outlets.
