ABSTRACT:
An adaptor for a windshield wiper blade to allow the wiper superstructure to be mounted to different diameter pin connectors associated with a wiper arm. Typically, wiper arms are provided with a side pin having either of two diameters. The adaptor bushing of the present invention allows a single wiper blade to be used with either pin type. The wiper blade includes laterally aligned apertures and a retainer spring clip to prevent inadvertent removal of the blade. With a larger diameter pin, the pin is simply placed through the aperture to engage the spring. With the smaller diameter pin the adapter bushing is positioned within the apertures to receive the pin. The adaptor has an offset throughbore such that when the pin is positioned within the adaptor, the spring clip will prevent withdrawal of the pin until the spring is released. The adaptor allows a supplier to stock a single style of replacement blade which can be mounted to either pin connector.
