Abstract
In an automotive vehicle, a dual directional slip clutch couples a windshield wiper arm to an electric motor and is operable to disengage the wiper arm from the drive motor during certain conditions. A range limiting system works in conjunction with the dual directional slip clutch and limits the degree of rotation of the windshield wiper arm. If the wiper arm becomes obstructed, the slip clutch will release the wiper arm from the motor thus preventing the motor from stalling ensures or damage to the system that is driving the wiper. The range limiting system ensures the correct alignment engagement when the wiper arm becomes un-obstructed. A single-direction slip clutch mechanism is provided for those instances where it is desirable to disengage the wiper arm from the motor when the arm is traveling in one direction.
