Abstract: A connector assembly for operatively connecting a windshield wiper arm to the superstructure of an associated wiper blade having a yoke member comprising a pair of spaced apart side sections and intermediate web section, the connector assembly including an opening formed in the web section and a pair of laterally aligned apertures formed in the side section of the superstructure, the terminal end of the wiper arm defining an opening adapted to be aligned with the apertures of the superstructure, a removable connector pin extending coaxially of the apertures and the opening for connecting the yoke member to the arm, and an insert member received at least in part within the opening of the yoke member and releasably connected to the pin, whereby the pin may be removed from the assembly in order to disconnect the blade from the arm.

Abstract: A wiper arm assembly is disclosed for use in operative association with a wiper blade and is adapted for typical, although not exclusive, application on vehicular windows, such as windshields, and rear and side windows. The wiper arm assembly of the present invention is operated by means of a drive motor which is located directly within the arm itself and is controlled by a plurality of electrical switches associated with a source of electrical energy, such as the vehicle battery. The assembly comprises inner and outer arm sections which are pivotably connected to one another and the aforementioned electrical switches are controlled by relative pivotal movement between the arm sections. One of the switches in the arm assembly functions to reverse the polarity of the electrical energy supplied to the drive motor, whereby to cause reverse rotation on the output shaft thereof and hence provide for oscillatory or reverse pivoting movement of the arm assembly.
