Abstract
A windshield wiper system for automotive vehicles includes a power source and a driver for causing a wiper blade assembly to swing, relative to the wiper arm, between an extended position of the wiper blade assembly and a retracted position of the wiper blade assembly. The power source and driver, which are selectively connected to one another, cause a link, which is attached to the wiper blade assembly, to swing as the wiper arm moves into and out of the hidden park position. A first embodiment uses a pressure fluid source as the power source and a piston as the driver to cause pivotal movement of the link as the wiper blade assembly moves into and out of the hidden park position. A second embodiment uses an electrical source as the power source and an electrical motor as the driver to cause pivotal movement of the link as the wiper blade assembly moves into and out of the hidden park position.
