Patent attributes
An air flow device for generating an air flow 30 across a windshield 4 of a vehicle 2, the air flow device has one or more means 10 for generating an air flow 32 located in proximity on a lateral end or side of the windshield 4, the one or more means 10 for generating an air flow 30 directs the flow of air laterally onto the windshield 4. The one or more means 10 for generating an air flow 30 has one or more fans 20 rotatable about an axis 22. Each fan 20 has a plurality of fan blades 24 for intaking air near the axis of rotation 22 of the fan blade 24, the fan blades 24 extend longitudinally having a cross section of increasing curvature to a substantially flattened unshaped terminal end 24E for directing the air flow 30 laterally. The one or more fans 20 can be driven by a single motor 25. Alternatively, each fan 20 may include a motor 25 for driving the fan blade 24.
