Abstract
A vehicle wiper system is provided including a cross-vehicle shaft that drives a pair of actuation mechanisms for driving a pair of wiper assemblies. The actuation mechanisms each include a crank, a connecting rod and a lever arm, whereby the connecting rod operably interconnects the crank and lever arm. The lever arm is fixed for rotation with a wiper post, which is in turn fixed to the wiper assembly. The actuation mechanism drives reciprocal rotation of the wiper post, thereby driving reciprocal sweeping motion of the wiper assemblies. The cross-vehicle shaft is driven by a motor that is controlled by a controller.
