The purpose of this study was to determine the injury potential in the case or rear end collision of the occupants head and neck by analyzing the distance between the head and headrest using two virtual multibody occupants. For this study, a rear impact was simulated virtually using PC Crash, the most common program used for accident reconstruction. The study was made by using 2 virtual multibody models, a basic multibody occupant included in PC Crash and a MADYMO occupant model. The distance of the headrest to the head varied from being close to the head (at about 110 mm from the normal position) to not using a head rest at all. This will simulate the position of the occupant when driving, while some drivers adapt a more close position to the steering wheel (head being far from the headrest) while others adapt a more relaxed position (head is near the headrest). The angles of the head and neck were measured and compared to medical limitations of them. Also the neck injury criteria (NIC) was calculated to evaluate the injury potential of the head rest distance variation.
