摘要

A mechanism for controlling the operating cycle of a wiper blade for cleaning a vehicle window comprises an arm rotatably mounted on a drive member whereby it can be reciprocated, a wiper blade carrier pivotally mounted at the outer end of the arm and means for rotating the blade carrier relatively to the arm as the arm is rotated, so that a blade on the blade carrier follows an elliptical path to sweep a large area of glass.
