AIRFOIL FOR A WINDSCREEN WIPER BLADE

摘要

AIRFOIL FOR A WINDSCREEN WIPER BLADE An airfoil for a windscreen wiper blade (1) comprises a vane member (9) intended to lie along side the blade (1) on the side of the blade (1) intended to be upstream of the air flow over the vehicle in use. The vane (9) is provided at its edge away from the windscreen with at least two clip members (15) which are intended to pass through apertures (7) in the base of the main yoke (3) of the windscreen wiper blade (1), the clips (15) or parts (25) thereof being flexible and resilient with respect to the vane proper (9) and are movable or have parts moveable thereon for engagement under the edges of the apertures (7) so as to retain the airfoil vane (9) in place.
