Abstract
A method of manufacturing a seat back includes placing a steel support structure within a mold and blow-molding a hollow plastic body onto the steel support structure to form a seat back with the steel support structure integrally supported within the body. The steel support structure may be a hollow, U-shaped steel tube having first and second attachment features at distal ends thereof for attachment to a lower seat structure.
