Abstract
Abstract The present assembly provides a seat assembly for motor vehicle having a light weight frame made of magnesium for easy removal and reinstallation of the seat assembly in the motor vehicle. The rear cross member of the seat cushion frame is an elongated body having a pair of cavities for high strength while at the same time providing means for attaching structural components to the seat cushion frame. The seat cushion frame components are formed with interiorly extending flanges for mounting the seat trim thereto. The mounting flanges include a notched portion forming a ledge against which a tail portion of a J-clip is seated to facilitate installation of the trim on the seat assembly.
