ABSTRACT:
A windshield wiper blade assembly is comprised of a flexible blade mounted to a pair of secondary yokes. A bridge joining the secondary yokes allows for quick release of the blade and yoke elements by outward deflection of the blade. The connection of bridge to secondary yoke also permits free rocking, within limits, of the blade in both directions relative to the bridge and the windshield, and a longitudinal sliding action which allows the blade to conform to a curved windshield during the wiper sweep without stressing the connection between the blade and secondary yokes.
