Abstract
A windshield wiper assembly includes a pair of leaf spring elements supported generally parallel to each other with a space therebetween. Each of the leaf spring elements includes a longitudinal slot formed therein at opposite ends thereof. A support bracket maintains the pair of leaf spring elements in generally parallel spaced apart relation to support the squeegee therebetween. A pair of end caps is mounted on opposite ends of the pair of spring steel elements. Each of the end caps includes a pair of detents for engaging the longitudinal slots formed in the spring steel elements and a pair of slots for receiving the ends of the spring steel elements therethrough. A longitudinal length of each of the detents is shorter than a longitudinal length of the longitudinal slots formed in the spring steel elements, so that the spring steel elements can slide with respect to the end caps.
