ABSTRACT:
An anti-freezing system for a windshield-wiper of a vehicle including a cut off device, which may be a relay, responsive to a temperature sensor which senses the ambient temperature. The cut off device energizes a heater to heat the windshield-wiper when and only when the ambient temperature as sensed by the temperature sensor is below a predetermined value. The system may include a control device, which may be a relay, responsive to the output of an electric generator provided in the automotive vehicle and adapted to disable the heater unless the electric generator is delivering power. The system may further include a manual override switch whereby the heater may be supplied with power, irrespective of the state of the cut off device. The heater may be provided extending along an elongated wiper support, or may be embedded in a wiper blade supported by the wiper support. The temperature sensor is preferably provided on the windshield-wiper in a position where the temperature sensor is free from the influence of the heater.
