A wiper blade assembly for mounting on an end of a wiper arm and engaging a windshield, the assembly comprising:

• an elongated main yoke pivoted at a central pivot on the wiper arm and having a pair of outer ends each formed with a throughgoing aperture;
• respective upper and lower secondary yokes pivoted at outer axes on the outer ends of the main yoke and having inner ends underlying the respective apertures and outer ends;
• respective tertiary yokes pivoted on the outer ends of the secondary yokes, the tertiary yokes having inner and outer ends formed as blade holders and the inner ends of the secondary yokes also being formed as blade holders;
• a wiper blade carried in the holders and engageable against a windshield;
• an outer wind-deflecting aerodynamic vane carried on each secondary yoke between the respective outer end and the respective outer pivot;
• at least one fin on each secondary yoke between the respective inner end and the respective outer pivot;
• and
• an inner wind-deflecting aerodynamic vane supported by the respective fin up away from each secondary yoke between the respective inner end and the respective outer pivot and aligned directly with the respective main-yoke aperture.
