Vehicle windscreen wiper blade - has blade edges curved to form wedge to scoop away water

摘要

The wiper blade has a curved base (16) with slide walls running at an angle from the connecting step (17). The end points (32, 33) of the side walls form a wedge (38) when they make contact with the windscreen at the beginning of each stroke to scoop away the water, leaving a continuous film of water behind which acts as a lubricant for the curved base. An alternative design has a flat base arranged between two sloping end pieces with the windscreen and wiper blade contact point laying at the junction of the sloped end and the flat base.
