Abstract
A windshield wiper drive linkage is provided for use in a wiper system. The linkage includes a crank arm connectible to an output shaft of a drive motor. A drive arm is pivotally connected to the crank arm for movement between first and second angular positions about a pivot pin with respect to one another. A flexible composite spring extends between the crank arm and the drive arm. The flexible composite spring is preloaded into an initial arcuate position and is bendable from the initial position to facilitate preventing damage to components in the wiper system when a load applied to the arms exceeds a predetermined load.
