Carbon Fiber Heating Pads

In each seat is a two section (three section on sport seats), heating pad. The sections are wired in parallel. The heating pads are resistors which when provided operating power from the seat heating switches produce radiant heat to the following temperatures.

The seat base heating element also contains a temperature sensor for feedback to the seat switch to provide the temperature regulation output control.
