Abstract
A windshield wiper system includes a windshield wiper having a wiper blade with a near end and a far end. The windshield wiper is configured for performing a relative rotation of the wiper blade between the far end and the near end of the wiper blade. A mechanism applying a torque to the far end during a sweeping motion of the windshield wiper twists the far end of the wiper blade relative to the near end. The mechanism may perform the relative rotation of the wiper blade regardless of whether the wiper blade is in contact with a windshield. For example, the mechanism may include a stationary cam block having a cam profile, and an actuator arm moving along the cam profile with the sweeping motion of the windshield wiper. The cam profile is suitably shaped to pivot the actuator arm in laterally outer ranges of the sweeping motion.
