1981 classified pedestrian post impact kinematics as one of the following conditions.
Roof vault pedestrian impact.
Wrap forward projection fender vault roof vault and somersault.
Pedestrian injury patterns are analyzed for each of the trajectory types.
The wrap trajectory and forward projection are the most common impact scenarios and are the only ones investigated in this study.
Five basic kinematic trajectories have been identified for frontal collision cases and are described as.
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.
Kinematics of pedestrian collisions ravani et al.
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.
Injury analysis of patients according to impact patterns involved in pedestrian traffic crashes.
In particular the injury severity score was highest in the roof vault group.
The vault maneuver is completed when the.
