ABSTRACT:
A covered windshield wiper includes a hub, a wiper arm having spaced apart side walls, and a pivot pin connecting the wiper arm to the hub. A pair of abutments coaxial with the pivot pin space the side walls of the wiper arm from the hub. A one-piece molded cover has a u-shaped cross section providing a base wall overlying the entire length of the wiper arm and the wiper blade, and laterally spaced side walls depending from the base wall and concealing from view both the wiper arm and the wiper blade. A hook molded on the cover engages the end of the wiper arm. A pair of snap tabs molded on the cover reach into the space between the side walls of the wiper arm and the hub to snap onto the pair of abutments and thereby removably attach the cover onto the wiper.
