Abstract
A wiper system for use with a windshield is provided and includes a wiper arm having a first and second end. The first end of the wiper arm includes a reaction surface disposed thereon while the second end includes a wiper blade biased into engagement with the windshield. In addition, a drive motor is fixedly attached to the first end of the wiper arm, whereby the drive motor includes a drive shaft operable to pivot the wiper arm across the windshield. A separator assembly is further provided and is supported by the drive shaft. The separator assembly is disposed within the arm and is operable to react against the reaction surface of the arm to selectively lift the wiper arm from engagement with the windshield.
