ABSTRACT:
A wiper arm assembly and system utilizing same is disclosed wherein a wiper arm of the assembly is alternately coupled to a wiper arm driver in first and second angular positions angularly spaced about a pivot axis to permit movement of the assembly to a park position and automatic movement between first and second limit positions of a glass wipe pattern. A manually operable coupling mechanism permits the movement and automatically locks the wiper arm to the wiper arm driver in the first angular position during movement towards the first limit position immediately after movement from the park position towards the second limit position. The coupling mechanism includes a locking member and a cam having first and second communicating grooves in which the locking member is alternately positioned. The cam is mounted on the wiper arm driver to rotate about the pivot axis. A manually operable portion of the locking member extends through a hole formed in the outer surface of the wiper arm to permit movement of the locking member between a locking position and a release position against the biasing action of a spring to allow relative angular movement between the wiper arm and the cam.
