ABSTRACT:
A refill unit for a windshield wiper blade having a resilient wiping element and a backing member with sidewardly extending flanges. A wiper blade superstructure has at least two articulated yokes or holders with claws on one of the yokes or holders engaging the flanges on said backing member. Abutments are struck from the walls of the body portion of the backing member for forming stops which engage the opposite ends of the wiping elements to prevent the wiping element from separating from the backing member. The abutments may be struck from the back of the backing member or from the sides of the backing member with the faces on the abutments facing toward the center of the blade.
