Abstract

A review of the existing mathematical models of a car occupant in a rear-end crash reveals that existing models inadequately describe the kinematics of the occupant and cannot demonstrate the injury mechanisms involved. The paper shows the results of a 78 degree-of-freedom model of the spine, head, and pelvis which has already been validated in plus G//z and minus G//x acceleration directions. It considers automotive-type restraint systems, seat back, and seat cushions, and the torso is free to slide up the seat back. Results of simulation runs show a good correlation with the existing data and experimental cadaveric runs made with a high seat back (or head restraint) and low seat back. The effect of seat-back stiffness and the restraint system on the response of the head and spine is studied.
