Abstract: A linkage comprising an elongated rod, a rod actuator to longitudinally reciprocate the rod, and a clip of flexible, resilient material connecting the rod to the actuator. The clip has a circular hub rotatably received in an opening in the actuator. The rod has a hook at one end received in a hole in the hub of the clip. The hole is elongated to enable the rod to be axially rotated to facilitate the insertion of the hook end in the hole during assembly. The clip has a stabilizing arm extending laterally from the hub. The rod is received in a transverse slot in the arm.

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.
