ABSTRACT:
A method of forming a metal and plastic composite structure including providing an elongated metallic element; providing first and second plastic sheets; heat forming the first and second plastic sheets to form first and second preformed plastic parts; and, following the individual heat forming of the parts and with the parts in a hot flowable state, assembling the plastic parts and the metallic element by fusing portions of the parts together with the metallic element positioned therebetween to form a composite assembly comprising a twin sheet plastic structure with the metallic element sandwiched therebetween. Also disclosed are composite structures, including a motor vehicle head rest and a seat back for a motor vehicle seat assembly, constructed in accordance with the invention methodology.
