Abstract
The invention provides a windshield wiper superstructure which is shaped to interact with an oncoming air stream so as to divert a component of force of such an air stream downwardly and toward the windshield, thereby to counteract any tendency for the wiper to lift in adverse aerodynamic conditions. The spine of the superstructure is inclined and defines a varying angle of attack to air flowing over the superstructure. Preferably, the angle of attack is maximized at joints between a central primary yoke and a pair of depending secondary yokes connected to distribute pressure from a wiper arm to a squeegee.
