ABSTRACT:
An impact-resistant electrical heating pad is characterized in that both upper and lower surfaces are antistatic. A preferred embodiment of the pad comprises a scrim fabric, a resistance heating wire carried by the scrim fabric, and sheets of high impact plastic material connected to opposing sides of the scrim fabric to form upper and lower plastic sheets. These impact-resistant plastic sheets have electrically conductive particles distributed throughout, so that the sheets themselves are electrically conductive. An electrical conductor is connected to the electrical resistance wire for energizing the same, and is also connected to the plastic sheets for eliminating static electricity from the pad. A ground fault detection circuit is connected to the electrical conductor to interrupt the power supply to the resistance heating wire if a short occurs.
