MATHEMATICAL MODEL FOR INVESTIGATING COMBINED SEATBACK-HEAD RESTRAINT PERFORMANCE DURING REAR-END IMPACT

A mathematical model of the seated driver subjected to A rear-end impact is developed using a lumped parameter model which, inter alia, allows for the investigation of the effect of an elastic-perfectly plastic head restraint device on the overall motion of the head and torso. The most satisfactory seatback-head restraint combination is found to be a seatback having a high rotational stiffness with A viscous damping coefficient of near 'critical' value combined with an energy absorbing head restraint having A plastic collapse load of approximately 890 n. The model confirms recent results which indicate that tensing of neck musculature prior to impact reduces injury potential.(a) /TRRL/
