The elastomer spring is mounted in the channel of the wiper arm to operate in compression tension or as a leaf spring to urge a wiper blade affixed at the outer end by the arm toward the windshield. The elastomer spring may be in the shape of a cylinder or pseudo-cylinder and may operate in linear or volumetric compression.
