Patent ID: 7285748

Claim:
A flexible seat heater for a vehicle, said heater comprising: a substrate having at least one open space extending therethrough; a polymeric layer of material applied to said substrate, wherein said substrate is adapted to limit elongation of said polymeric layer when said substrate is subjected to a flexing action so as to improve durability of the polymeric layer, said polymeric layer including a conductive layer and a resistive layer, said conductive layer forming a buss structure which includes a first buss member electrically connected to a positive polarity and a second buss member electrically connected to a negative polarity; and an electrical power source connected to said buss structure such that electrical current flows on a path from one of said first and second buss members, to said resistive layer and then to the other of said first and second buss members as the current travels from one of said positive and negative polarities to the other so as to generate heat, said polymeric layer of material being adapted to regulate and distribute the heat.
