Abstract: A heated mirror system for use in motor vehicles that includes the use of a thermally regulating material that eliminates electrical heater elements used in conventional heated mirror systems. The heated mirror system includes a mirror housing constructed from an electro thermally-active thermoplastic material. The electro thermally-active thermoplastic material is selected to be self-regulating such that the material heats up until it reaches a selected temperature at which point the resistivity of the material prevents further heating of the mirror housing to reduce the risk of damage to the mirror. The mirror is located in thermal contact in the mirror housing such that, as the electro thermally-active thermoplastic material heats, at least a portion of the heat is capable of heating the mirror. The mirror housing may be constructed using an injection molding process.
