  • Heated toilet seat
    Patent number: 5940895
    Abstract: A heated toilet seat with an outer clam shell type housing and an inner clam shell type housing. A heater wire is positioned in the inner housing to distribute heat. The inner housing is held above the bottom portion of the seat so that little heat is wasted by passing down through the bottom portion. The inner housing can be of essentially the same geometric configuration as the top and bottom portions of the outer housing, and groove and rib structures can tightly enclose the wiring in the inner housing.
