Roof Vault Pedestrian Impact

Kinematics of pedestrian collisions ravani et al.
Roof vault pedestrian impact. Pedestrian injury patterns are analyzed for each of the trajectory types. The fourth impact orientation is the roof vault which begins initially like a wrap trajectory but in this case the pedestrian s legs do not stay ahead of the vehicle. In particular the injury severity score was highest in the roof vault group. Injury analysis of patients according to impact patterns involved in pedestrian traffic crashes.
An injury risk index is defined. Chest and abdomen were the most severe in the fender vault group and head and neck injuries were the most severe in the roof vault group. The vault maneuver is completed when the. And the associated injury risks are compared.
Due to the impact forces the legs continue to rotate upward with the pedestrian essentially standing on his head on or near the roof line. Five basic kinematic trajectories have been identified for frontal collision cases and are described as. Wrap trajectory forward projection fender vault roof vault or somersault.
