Abstract

An improved chair back is formed of a molded construction uses multiple mold shots of mold materials to develop different performance characteristics in selected areas of the chair back. The chair back has the appearance of a unitary molded panel, but is formed from multiple mold shots which preferably are performed at multiple stations on a mold tool. By providing multiple mold shots and selected materials to form different areas of the chair back, different performance characteristics are generated including the provision of a peripheral frame providing structural rigidity to the chair back, a lumbar support panel which provides localized support to the lumbar region of the chair occupant, and a thin sheet-like support panel extending between the frame and enclosing the interior region defined between the peripheral frame to provide a more flexible and pliant surface providing more comfortable contact with the occupant's back.
