An articulated windshield wiper blade superstructure for distributing applied pressure proportionately along the length of a wiper blade which includes a central primary lever and a pair of secondary end levers arranged end to end. The end levers are pivotally connected to the central levers. A single flat spring extends from end to end through the central lever. At each end it engages a projection on the end levers which extends inwardly of the pivotal connection. The spring functions to distribute the arm pressure to the end levers and also functions as a latch to retain the blade on the arm. |
