Abstract
An improved windshield wiper is disclosed. The wiper comprises an upper portion and a lower portion connected by a flexible neck portion. The lower portion comprises a body, and a lip for contacting the windshield. The body supports the lip and is connected to the neck portion. Portions of the body in the areas below connection of the upper portion to supporting superstructure are laterally removed from the extremity of the body inwardly a predetermined distance. Material is not removed from the lip or neck portion. The removal of the material in these areas reduces support of the lip by the body in the removed areas to thereby reduce excess pressure concentrations in, and equalize pressure distributions along, the wiper lip in the vicinity of the connection of the upper portion to supporting superstructure when it is pressed into contact with the windshield by the supporting superstructure.
