A unitized superstructure for a wiper blade comprises an integrally formed articulated structure consisting of a central primary span and a pair of secondary spans connected at each end of the primary span. The primary span is channel-shaped in cross section and includes planar extensions at its ends which connect the secondary spans at their centers to the primary span. Adjacent each end of the primary span are a pair of depending tabs which embrace a portion of the secondary spans. The superstructure is formed with the longitudinal axes of the secondary spans substantially perpendicular to the longitudinal axis of the primary span. The secondary spans while still pliable are rotated approximately ninety degrees into an operative angular relationship with the primary span and retained in that position by engagement of cooperating latch elements on adjacent spans. The planar end extensions on the primary span form flexible elastic connectors. A squeegee assembly comprises an elastomeric strip supported by a backing strip having a pair of longitudinal rails. At each end of the secondary yoke is a pair of opposed claws which slidably receive the backing strip.
