Abstract
A wiper blade having a superstructure (1,2) linked to wiping element (8) which is reinforced by a longitudinal pressure distributing profile (7,20) provided with a first air deflecting device (9) consisting of a deflector (10) located at a certain distance (d1) from the wiping element (8) and that one or more longitudinal openings (11) are provided between the longitudinal pressure distributing profile (7,20) and the deflector (10). The lower edge of the deflector (10) is located at a certain distance (d2) from the surface to be wiped (18) such that the ratio between (a) the distance (d1) between the deflector (10) and the wiping element (8) and (b) the distance (d2) between the lower edge of the deflector (10) and the surface to be wiped (18) is substantially equal to ten. Optionally, a second air deflecting device (21) is attached to the longitudinal pressure distributing profile (20) of the wiping element (8) on the side opposed to the first air deflecting device (9).
