Abstract

A support for conventional windshield wiper blades for motor vehicles which precludes oxidation of moving parts thereof and permit noiseless operation of the wipers, which support comprises a rectangularly cross-sectional arcuate central rod with a pair of curved terminals connected to rocker arms of plastic material, a pair of hollow seats in the central part of the rocker arms for receiving the curved terminals, and trough-like seats at the ends of the rocker arms for retaining the conventional reinforcing metal strip of the wiper blade.

Claims

1. In a support for windshield wiper blades for motor vehicles having a central metallic arcuate rod with curved terminals and a pair of plastic rocker arms connected to the central rod, the improvement consisting of a hollow seat in the central portion of each of said rocker arms shaped as a T and composed of two interconnected cavities provided therein and substantially normal to each other with an intermediate fit entry for movably retaining within one of said cavities of said seat said terminals of said arcuate rod, said terminals being curved away from the rocker arms and toward the arcuate rod and said rod having a substantially rectangular cross-section.

2. The improvement according to claim 1, wherein said fit entry intermediate said interconnected cavities has a single surface thereof curved to facilitate the insertion of the terminal into said seat and the movability of the terminal when inserted therein.
