ABSTRACT:
A windshield wiper assembly includes a flexible wiper element and a semi-rigid backing strip, the wiper element having a curved roller back configuration to maintain the point of contact with the backing strip substantially directly above the wiper lip to reduce the force necessary to flip the wiper element upon reversal of wiping motion. The wiper element includes an involute tooth and head to retain the wiper element in the backing strip and to allow relatively unrestricted floating movement therein.
