Özet
The posture of the occupant at the time of impact in a road-traffic accident is very influential on the injury outcome. In rear-end crashes, a typical out-of-position posture prior to impact is the leaning forward posture. This study presents the validation of a 50th percentile male multi-body human model against volunteer response in leaning forward posture prior to rear impact. The responses of the human body model are compared to those of the volunteer and the BioRID II dummy. The simulation results indicate that the kinematic responses of the human-body model are quite similar to those of the volunteer whereas the BioRID II dummy responses are not biofidelic. Therefore, the human-body model can be reliably used in rear impact simulations with leaning forward posture or in simulations where the seatback angle is large, producing a large backset between the head and head-restraint.
