Publication number: 20090014437Abstract: The present invention provides a heating element with electrically insulated metallic filaments wherein those metallic filaments have a diameter of 2 to 200 ?m, each metallic filament is separately electrically insulated and the electric insulation is a continuous and coherent glass coating. This provides thus a product which is very corrosion and oxidation resistant and has a high cut resistance. The high cut resistance makes it highly suitable for being sewn in textiles, e.g. in car seating. A further advantage of the invention is the small dimensions of the material used which make it more flexible thereby increasing the wear resistance and also increasing the flexibility for use, e.g. weaving, knitting or braiding the product into textile products. The metallic filaments can be of a metal with a specific electrical resistance between 17 and 2000 ?.mm2/km. Preferably, a specific electrical resistance between 17 and 200 ?.mm2/km, even more preferably, a specific electrical resistance between 17 and 100 ?.Type: ApplicationFiled: February 6, 2007Publication date: January 15, 2009Inventors: Wim Van Vooren, Steve Verstraeten, Pol Speleers
