Abstract

The invention involves creating a thinner structured seat capable of complying with the federal requirements. The steel back pan is rigidly mounted on three edges to the back frame seat structure. The bottom of the back pan is unformed and allowed to flex in the fore-aft direction. The back pan is then covered with foam that may be one third as thick at the bottom as to thickness at the top of the back pan. The three to one ration of the lower to upper portion for the foam is important in achieving seat thinness. When seat spacing is measured at the h-point or cushion level, the knee protection zone is thinner than conventional seats and allows for a greater number of seats to be placed into a school bus. Utilizing a flexible steel back pan combined with foam in the proper ratios to absorb energy in the knee protection zone through the upper portion achieves the invention.
