ABSTRACT:
Each mat of a plurality of mats has an electrical resistance heater embedded therein between a layer of vinyl and a layer of cloth-like material. The mats are located in a motor vehicle and are connected to the power system of the motor vehicle via a cigarette lighter-type attachment and are controlled by a control element. Each mat has a crown and a gutter so water generated by melting snow or ice is controlled and prevented from running off the mat.
