Abstract
A heated wiper system is provided for mounting on a wiper arm of a windshield wiper assembly of a vehicle. A wiper blade selectively mounts on the free end of the wiper arm having a resilient wiper element arranged to slidably receive a heating element therein. A connector selectively mounts the heating element and an associated thermostat to an electrical supply of the system enabling the thermostat and heating element to be replaced independently of the wiper blade. When more that one wiper blade is provided, the respective heating elements preferably have lengths which correspond to the length of the respective wiper elements within which they are mounted. When the heating elements are of different length, a longest one of the heating elements preferably has a lower electrical resistance per unit length thereof than a shortest one of the heating elements. Total electrical resistances of the respective heating elements may thus be substantially equal.
