Wiper Blade: Description and Operation
Operation
OPERATION
The wiper blades are moved back and forth across the glass by the wiper arms when the wipers are being operated. The wiper blade superstructure is the
flexible frame that grips the wiper blade element and evenly distributes the force of the spring-loaded wiper arm along the length of the element. The
combination of the wiper arm force and the flexibility of the superstructure makes the element conform to and maintain proper contact with the glass,
even as the blade is moved over the varied curvature that may be encountered across the glass surface.
The wiper element flexor provides the claws of the blade superstructure with a rigid, yet flexible component on the element which can be gripped. The
rubber element is designed to be stiff enough to maintain an even cleaning edge as it is drawn across the glass, yet resilient enough to conform to the
glass surface and flip from one cleaning edge to the other each time the wiper blade changes directions.
