ABSTRACT:
The invention seeks to provide an improved wiper blade assembly, and in a broad aspect provides a windscreen wiper blade assembly comprising at least a primary yoke and a pair of secondary yokes articulated thereto, the primary yoke and/or the secondary yokes being provided with at least one wind-deflecting surface, oriented in relation to the direction of motion of the vehicle so that when said vehicle is moving to create air flow over the windscreen, air is deflected by said surface or surfaces to produce a force tending to urge the wiper blade assembly towards the windscreen of the vehicle.
