Electric Heating Element Patents (Class 297/180.12)
  • Publication number: 20080011732
    Abstract: 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. The occupancy conditions are detected based on changes in a capacitance between the upper electrode and a member grounded to a vehicle body. To reduce a capacitance between the upper electrode and seat heater and to thereby improve sensitivity of the detection of the occupancy conditions, an alternating voltage that alternates in accordance with an alternating voltage supplied to the upper electrode is supplied to the lower electrode.

  • Patent number: 6541737
    Abstract: A temperature detector for an air-conditioned vehicle seat with seat heating and/or seat ventilation is disclosed. To ensure accurate temperature measurement for regulation purposes close to the surface of the seat cushion while eliminating purely local temperature peaks, the temperature detector is provided with a flat, extended heat absorption surface, which is preferably formed by a thin, flexible layer of good thermal conductivity in which a temperature sensor in button or disc form is firmly embedded.

  • Patent number: 6531687
    Abstract: A two-dimensional heating element, especially for seat heaters in the motor vehicle sector, having a textile base material and contact conductors and heating conductors which are electrically conductive and touch one another. The contact conductors delimit heating areas. The heating conductors are laid effectively in the direction of stitch wales and orthogonal to the stitch wales in such a way that there are at least two zones functioning at least as a main heating area and at least as a secondary heating area with different heating capacities.

  • Publication number: 20030006633
    Abstract: An induction heatable body (22) that quickly heats to a desired temperature, retains heat long enough to be used in almost any application, and develops no “hot spots” even when heated by a heating source having an uneven magnetic field distribution. The induction-heatable body (22) achieves the foregoing while remaining relatively lightweight, inexpensive and easy to manufacture. The induction-heatable body (22) includes a plurality of induction-heatable layers (32a, b, c) each sandwiched between alternating layers of heat retentive material (34a, b, c). The induction-heatable layers (32a, b, c) consist of sheets of graphite material that can be inductively heated at magnetic field frequencies between 20 and 50 kHz. The heat-retentive layers (34a, b, c) consist of solid-to-solid phase change material such as radiation cross-linked polyethylene.

  • Publication number: 20020175541
    Abstract: A seating device having an air conditioning unit fluidly connected to a substantially hollow air diffuser. The air diffuser has a plurality of apertures through which cold air generated by the air conditioning unit is exhausted. The air diffuser serves as a back rest for the seating device. The air diffuser sits in a channel defined by the back surface of the seating member of the seating device, the horizontal support member on an L-shaped support bracket, and the front surface of the vertical braces of the L-shaped support bracket.

  • Patent number: 6481801
    Abstract: The present application pertains to a seat pad particularly for motor vehicles seats, with a core portion made of expanded plastics material. The upper side of the core portion facing the seat surface is provided with channel-like grooves, so that the geometry of the remaining core portion allows an optimum distribution of the seat pressure because of the good adaptation to the human anatomy.

  • Publication number: 20020149237
    Abstract: The invention relates to a head restraint for vehicles of any kind with a support with upholstery portion. The head restraint is comprised of two detachably connected half shells which have collectors for receiving and collecting light, corresponding solar modules for conversion of the light into electrical energy, and storage elements for storing this energy. The half shell of the head restraint, arranged rearwardly in the travel direction, has a frame for receiving a detachable component for various purposes, such as an illuminated vanity mirror, a screen, or the like. Within a second removable component, polymer electrolyte membrane fuel cells with a hydrogen cartridge can be provided for additional energy generation.

  • Patent number: 6435608
    Abstract: 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.

  • Patent number: 6378948
    Abstract: 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.
