Abstract

A heated element assembly and method of manufacturing heated element assemblies is provided. The heated element assembly including a first and second molded sections shaped to mate with each other is provided. A resistance heating element is secured between the first and second molded sections by an interference fit. The resistance heating element includes a piercable supporting substrate and a resistance wire sewn thereon. The resistance wire is disposed in a predetermined circuit path which is substantially encompassed by the first and second molded sections. The resistance heating element is easily fixed in a position between the first and second molded sections and is capable of providing heat on vertical, horizontal and contoured surfaces.
