Air wiper mechanism for vehicle

An air wiper mechanism comprising:

• a first air ejection unit having plural nozzles for spouting air fed from said compressed air supplying means upward along the outer surface of a windscreen glass to form a first air curtain at a position near the surface of said windscreen glass, said plural nozzles being positioned in front of and near the lower end of said windscreen glass and being arranged along the lower end of said windscreen glass at predetermined spaced intervals;
• a second air ejection unit having a nozzle for forming a second air curtain through an oscillating movement, said second air curtain being spaced away from said windscreen glass more than said first air curtain, said nozzle being arranged in front of and near the lower end of said windscreen glass so as to spout upward air fed from said compressed air supplying means and the nozzle of the second air ejection unit being mounted to oscillate over the outer surface of said windscreen glass in a substantially parallel direction to a direction in which air is spouted from the first air ejection unit;
• and
• oscillating and driving means for performing said oscillation movement of the nozzle of the second air ejection unit;
• said second air ejection unit including plural nozzles divided into at least two nozzle parts, said nozzle parts being arranged respectively at different slope angles with respect to said windscreen glass so as to form at least two small air curtains spaced away from said windscreen glass;
• and
• warm air supplying means for feeding warm air upward from a position in front of and near the lower end of said windscreen glass and along the outer surface of said windscreen glass.
