ADJUSTABLE BLADE LOAD MECHANISM FOR CANTILEVER BEAM WIPER ARM ASSEMBLY

A windshield wiper system has a drive arm with a drive shaft connector, a curved cantilever beam, and a wiper blade assembly. The drive arm is configured to connect to a drive shaft at the drive shaft connector. The curved cantilever beam is connected to the drive arm with a first drive arm fastener and a moveable drive arm fastener. The first drive arm fastener is positioned on the drive arm between the drive shaft connector and the moveable drive arm fastener. The moveable drive arm fastener is positioned at one of a plurality of moveable drive arm fastening positions. The wiper blade assembly is connected to the curved cantilever beam with a wiper blade fastener positioned at a wiper blade assembly fastening position on an outboard tip of the curved cantilever beam. The curved cantilever beam has an effective length extending from the moveable drive arm fastener to the wiper blade assembly fastener such that a blade load exerted by the curved cantilever beam on the wiper blade assembly is a function of the effective length
