Abstract
A windshield wiper for a motor vehicle which performs a swinging-wiping movement across a rectangular-shaped windshield between end positions that are located adjacent to one of the long sides of the rectangular windshield. The wiper blade is constructed and arranged to have the operative length thereof varied during the wiping movement whereby in the central position the blade is substantially equal to the length of one of the short sides of the rectangular-shaped windshield. In other sectors of the surface to be wiped, the wiper blade is of a greater length.
