Abstract (en)

[origin: US5811760A] A heating device for water beds comprises a plurality of electrical resistance conductors arranged between a bed frame and a safety foil, means for controlling the conductors in dependence on the desired temperature of a water core locatable under the safety foil, a plurality of ceramic plates arranged so that the conductors are burnt-in the ceramic plates, a bending resistant metal plate having a lower side, the ceramic plates being glued to the lower side of the metal plate by an adhesive having high thermal conductivity, and a base plate having poor thermal conductivity and placeable on the bed frame, the metal plate being arranged on the base plate in a form-locking manner with an air gap for the ceramic plates.
