Publication number: 20080011732Abstract: An electrode unit for detecting whether a seat is occupied or not (occupancy conditions) is embedded in a seat of an automotive vehicle together with an electrically powered seat heater. Both of the electrode unit and the seat heater are flat, and the electrode unit is laminated on the heat heater. The electrode unit is composed of an upper electrode, a lower electrode and an insulating film disposed between both electrodes.

Patent number: 6435608Abstract: A seating device having a heat source fluidly connected to a substantially hollow bench which defines an interior space, a substantially hollow deck extending outwardly from the footwall of the bench, perforations in the frontal wall of the base to exhaust pressurized heated air from the interior space of the bench into the deck, and perforations in the top surface of the deck to exhaust pressurized heated air from the deck and into the atmosphere. The pressurized heated air warms the entire outer surface of the bench and the deck. The pressurized heated air exhausting from the perforations in the top surface of the deck warms the entire region in front of the bench. The seating device provides heat to the entire body of a person sitting on its bench or standing on its deck.Type: GrantFiled: November 17, 2000Date of Patent: August 20, 2002Assignee: Reliable Construction Heaters, IncorporatedInventor: Franklin B. Floyd, Jr.

Patent number: 6378948Abstract: A supporting part for a seat has at least one plastic layer made of a material composed of thermally reversibly deformable material. The plastic layer can be shaped from a first shape into any predeterminable second shape at a shaping temperature higher than its temperature of use and can be fixed in this reversible shape at a temperature range lower than the shaping temperature. This layer can also be returned to its first shape by reheating it up to the shaping temperature. Another layer arranged as a heating layer is provided to apply a thermal treatment to the intermediate layer made of a material that can also o be reversibly deformable.Type: GrantFiled: March 27, 2000Date of Patent: April 30, 2002Assignee: Magna Reflex Holding GmbHInventors: David Macher, Heinz Zorn
