ABSTRACT:
Vehicle heating systems such as portable vehicle cushions, steering wheel covers, and other interior surfaces include a direct current heating circuit for producing heat when activated; a surface material covering the heating circuit to isolate the heating circuit from direct contact by a vehicle occupant or object resting against the surface material; and a pressure switch located below the surface material and connected to the heating circuit to activate the heating circuit during application of sufficient pressure on the pressure switch by a vehicle occupant resting against the surface material at a location proximate the pressure switch, insufficient pressure being applied to the pressure switch deactivating the heating circuit.
