Abstract
A wiper blade for motor vehicles has a wiping element (6) attached to a superstructure which includes a main bridge (1), one or more intermediate yokes (2) and one or more secondary yokes (3), with at least one of the components (1,2,3) of said superstructure replaced by at least one air deflecting device (14). In a preferred form, at least one air deflecting device replaces at least one secondary yoke, with each air deflecting device (14) extending parallel to and at a certain distance from the wiping element (6) of the wiper blade. The air deflecting device or deflector (15) has attachment members (16,19,21) for securing the deflector to one of the components (2) of the superstructure of the wiper blade and has additional attachment members (17,4') for securing the deflector to the wiping element (6) of the wiper blade. The deflector has at least one resilient blade (18) capable of exerting a pressure on the wiping element (6) of the wiper blade. The invention results in a wiper blade having a ratio of the distance between the deflector (15) and the wiping element (6) and the distance between the bottom edge (15') of the deflector (15) and the surface to be wiped (12), which ratio is substantially equal to ten.
