Front Wiper Blade: Operation

The front wiper blades are moved back and forth across the glass by the front wiper arms when the wipers are being operated. The wiper blade flexor is the flexible member secured the length of the wiper blade element that 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 flexor 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 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.
