A three-dimensional mathematical model of an aircraft seat, occupant, and restraint system has been developed as an aid to the development of crashworthy seats and restraint systems for general aviation aircraft. The occupant model consists of eleven rigid mass segments whose dimensions and inertial properties have been determined from studies of human body anthropometry and kinematics. The seat model is made up of beam and membrane elements with provision for simulating plastic behavior by the introduction of plastic hinges in the beams. A user-oriented computer program called Seat Occupant Model-Light Aircraft (SOM-LA) based on the three-dimensional model has been developed for use by engineers concerned with design and analysis of general aviation seats and restraint systems in that detailed descriptions of both are used as input. The response of the seat and occupant, restraint system loads, and various injury criteria are predicted for any given set of crash conditions.
