This report shows the frequency of injured body regions of drivers in frontal crash cars by injury severity level, and then compares some different rates of injured body regions in different situations; such as with and without seatbelts, and with and without evasive actions (e.g. breaking and/or steering) using accident data. Comparison using the data indicates that there were some different injury rates of the chest, abdomen, head and especially the lower extremities in situations with and without evasive actions in the cases of drivers without seatbelts. This report also contains results of computer simulations (MADYMO) which show driver motions in four different situations in frontal crash cars: without seatbelts + evasive action / without seatbelts + no evasive action / with seatbelts + evasive action / with seatbelts + no evasive action. The results allow the motions of the driver to be visualized in each of these situations. The simulations clarify the results of the accident data which showed a significant correlation between injury rates of the lower extremities and the use of seatbelts and/or evasive action.
