Abstract
A flexible surface heating element, particularly for seat heaters, having a heating field of conductive fibers electrically connected to at least one contact strip. The contact strip contains a portion of conductors in the form of steel filaments and a portion of conductors in the form of filaments of a higher conductivity than that of the steel filaments. The two types of conductors are electrically interconnected and affixed by means of a yarn on a textile band, the conductors of higher conductivity extending above and/or under the steel filament conductors and being electrically connected to the steel filament conductors. A method for producing the flexible heating element is also provided.
