  • Patent number: 10960731
    Abstract: Heating element for user-touchable areas in a vehicle with a foamed carrier material in which at least one heating conductor, which comprises an electrical insulation, is embedded, and with connecting conductors which are electrically connected to the ends of the heating conductor via at least one connection part and form an electrical feed line. The at least one connection part is arranged within the foamed carrier material and the connection part is foam-covered in an electrically insulating manner by the carrier material. The connection part is brought into electrically conductive contact at least partially with the respective connection end of the heating conductor due to applied pressure and/or applied heat, at least partially destroying the electrical insulation in the region of the connection part. Furthermore, a method for producing such a heating element using a mold tool is indicated.
    Type: Grant
