ABSTRACT:
A windshield wiper refill wiping unit includes a squeegee element supported by a sinuous backing strip in which the central portion is convex in the direction facing the squeegee element and the end portions are concave on the side facing the squeegee element. The unit may be supported in an articulated superstructure having outboard claws which are disposed adjacent the end of the backing strip or in a superstructure having outboard claws which are spaced a substantial distance from the ends of the backing strip; it will produce improved pressure distribution in either type of superstructure.
