The vault maneuver is completed when the.
Roof vault pedestrian impact.
Injury analysis of patients according to impact patterns involved in pedestrian traffic crashes.
The wrap trajectory and forward projection are the most common impact scenarios and are the only ones investigated in this study.
Wrap trajectory forward projection fender vault roof vault or somersault.
Kinematics of pedestrian collisions ravani et al.
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.
Wrap forward projection fender vault roof vault and somersault.
1981 classified pedestrian post impact kinematics as one of the following conditions.
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.
And the associated injury risks are compared.
Pedestrian injury patterns are analyzed for each of the trajectory types.
