The motivation for this project was to design, and develop an aircraft seat to meet the proposed FAA 32g vertical/longitudinal dynamic test requirements specified in NPRM 93-71. A major goal of the design was to develop a production-quality seat in terms of weight, comfort, appearance, simplicity, and manufacturability. The relevant injury criteria was to obtain an occupant lumbar (spinal) load below 6670 N (1500 1bf). The design incorporated energy absorbing devices in the cushion and chair legs. The seat developed was based on the Beech King Air design and incorporated a modified seat frame, seat back, and reclining mechanism. The seat cushions were provided by Oregon Aero, while the seat pan and seat legs were designed and manufactured at WSU.
