Occupant injury in automobile rear-end collisions is becoming one of the most costly and aggravating traffic safety problems. Designing seat and head restraints to help limit injury associated with rear-end impact can become more efficient by using new mathematical modeling techniques. Using the facet surface modeling technique in MADYMO a model is developed that captures the interaction between occupants and seat/head restraints with a high degree of geometric accuracy while maintaining efficient computer run times. One such model is validated using a prototype seat/head restraint and the TRID (TNO Rear Impact Dummy), both using facet surface techniques. From this model a study is done to compare the results of the TRID model and the results from a Hybrid III model with the results from a Human neck model. This study is performed in several different head restraint positions.
