separately and quickly and easily installed in the vehicle such as to the cigarette lighter or to an existing fuse in the vehicle 39 s electrical system with a minimum of effort and a maximum of effect referring again to fig1 and also to fig2 the foot warmer 10 according to the first preferred variant includes a rubberized mat construction preferably the mat is constructed of first 12 upper and second 14 lower mat layers and which are constructed of rubber or other suitable heat transferable and electrically insulated material the mat layers may further be constructed in any shape desirable such as a generally rectangular configuration which is best suited for application to a vehicle floor and it is also envisioned that the mat layers may be removable or in certain application such as during the manufacture of the vehicle fixedly secured to the floor it is also contemplated that the mat construction of the warmer 10 can substitute for a typical vehicle floor mat and such as may be positioned on the floor below the vehicle operator or any of the vehicle passengers and within the scope of the instant invention disposed between the layers 12 and 14 of the rubberized mat construction is a wire resistor coil 16 the coil 16 operates to dissipate resistance created from a circuit located at unit 18 positioned at an edge location of the warmer mat 10 the generation of heat as a byproduct of electrical resistance is very well conventionally known such as through the application of basic tenets of electrical technology and in particular ohm 39 s law.
