Abstract
A windshield wiper has a wiper arm (10), which is driven via a drive shaft and is made up of a fastening element (12) and a hinge element (14), pivotably connected to it via a swivel joint (18). The hinge element has a wiper rod (36) to which a wiper blade (42) is pivotably connected, and at least one spray nozzle (42) is disposed on a pivotable part (10, 22), the spray nozzle communicating with a water pump via a water line (48). An electric resistance heating line (50, 60) in wire form is guided through the water line (48) and has two insulated current-carrying leads (64, 66), which on one end are electrically connected to one another and on that end, with the spray nozzle (42, 54) of a heating-conducting material, form a contact point (62, 68) with good heat transfer.
