ABSTRACT:
A wiper assembly has an arm head which reciprocates with respect to a center line of a wiper arm by receiving motive force from a reciprocating rod. An elastic component is coaxially provided proximate to the center of rotation. When the coefficient of friction between the wiper blade and the windshield surface is inversely proportional to the speed of the wiper blade causing self-induced vibration in certain circumstances, the wiper blade tends to screech, skip or chatter across the windshield surface. Such vibration is suppressed by the elastic component, thereby permitting smooth reciprocal motion of the wiper assembly.
