ABSTRACT:
A vehicle seat assembly includes an aluminum lower seat frame with first and second side supports having a thickness of less than four mm throughout a substantial portion thereof. The seat back frame is pivotally connected to the lower seat frame and comprises a contoured structural reaction injection molded (SRIM) material. In an alternative embodiment, the back frame comprises a plurality of glass mat layers enclosed within a molded urethane material. Extra glass mat layers are provided in high stress concentration areas for added structural integrity.
