ABSTRACT:
An aircraft windshield wiper arm assembly adapted particularly for use with curved windshields, the wiper arm assembly having a hub mountable on an oscillatory wiper drive post and an elongate wiper arm cantilevered from the hub with a wiper blade carried on the free end of the arm. The arm is so shaped that its moment of inertia decreases progressively from its fixed to its free end and the arm is preferably formed so as to assume a curved, unflexed position. An adjustment is provided for flexing the arm from its unflexed, curved position to a substantially flat position so that with the wiper blade bearing on the windshield, the arm exerts a desired force on the wiper blade as the windshield wiper arm assembly is swept over a curved windshield.
