ABSTRACT:
A heating apparatus includes a carbon fiber heating layer placed in a positioning jacket which is mounted in a seat cushion, a conducting coupler electrically connected to the carbon fiber heating layer, and a control switch electrically connected to the conducting coupler. Thus, when the connector of the control switch is attached to the conducting coupler, and the plug of the control switch is inserted into the cigarette lighter of the car, the electric current from the car battery in turn flows through the control switch, the conducting coupler and the conducting cord into the carbon fiber bundles which produce an impedance to convert the electrical energy into a heat energy to heat the seat cushion to warm the user seated on the seat cushion, thereby providing a comfortable sensation to the user.
