ABSTRACT:
A pressure distributing superstructure for a windshield wiper, comprising a plastic primary yoke having at each end oppositely extending, coaxial pins and a lobe beyond the pins, and two plastic secondary yokes, each having a pair of ears spaced apart along the axis of the pins, the ears of each pair having opposing openings for receiving the pins of one end of the primary yoke, a shoulder above each opening to retain the pins therein, and a downwardly and inwardly sloping ramp above each shoulder, the ends of said pins of a pair being separated by more than the minimum spacing of the ramps, the ears being sufficiently resilient so that when the pins are forced between the ramps the ears will temporarily be flexed apart to allow the pins to snap into the openings.
