ABSTRACT:
An improved windshield wiper blade insert for mounting on a wiper blade carrier arm comprises a base portion, a shank portion and a wiping portion. The shank portion comprises an elastic response enhancing material. The material is preferably a metal that exhibits substantially total elastic recovery under the flexural stress and service conditions encountered by the wiper blade insert. In one embodiment, the shank portion contains a ribbon of spring metal with a thickness in the range of about 0.001 to about 0.004 inches. In a second embodiment, the elastic response member is an essentially rectangular solid formed from spring metal wire with a diameter in the range of about 0.001 to about 0.006 inches.
