Maximum Head Displacement of Vehicle Occupants Restrained by Lap and Torso Seat Belts in Frontal Impacts 1999-01-0443
This study presents an efficient method for accident reconstructionists to determine the expected forward head displacements of automobile occupants who are restrained by lap and torso seat belts during frontal impacts. Data were referenced from various research investigations; thus, a wide range of different test conditions, configurations and subjects were considered. The impact severity of the tests ranged from 16 to 60 km/h. Results presented in this study provide a practical method to determine the expected head excursion for occupants who are restrained by lap and torso seat belts during frontal impacts.
