Abstract
A windshield wiper arm includes a free end which is U-shaped in cross section to form depending ears. The ears include slots open at the free end and detents adjacent the rear edges. The depending ears are received in an opening of the web of the central portion of a channel shaped blade and straddle a flat leaf spring. The open ended slots engage a cross pin extending through the webs of the blade and the detents engage the underside of the flat leaf spring to limit angular displacement of the blade relative to the arm. A pair of shoulders formed on the inner surfaces of the side walls of the blades engage the rear edge of the depending ears to restrict longitudinal movement of the arm relative to the blade.
