ABSTRACT:
According to the invention, an attachment structure is provided and has a body with a configuration for connection to a wiper arm. The attachment structure may have one or any combination of an airfoil, a washer fluid conduit or receptacle or an air dam integrally formed on or carried by the body. The attachment structure is elongate and may have an airfoil, an air dam and/or a washer fluid conduit or receptacle integrally formed on the body and will extend lengthwise of the wiper arm in assembled relationship therewith. The cross-sectional configuration of the body and wiper arm is substantially uniform throughout the length of the structure. Because extrusion molding is cheaper than injection molding, a high integrity, plastic device can be produced at a lower cost than conventional injection molded structures.
