And the associated injury risks are compared.
Roof vault pedestrian impact.
The vault maneuver is completed when the.
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.
The wrap trajectory and forward projection are the most common impact scenarios and are the only ones investigated in this study.
An injury risk index is defined.
Pedestrian injury patterns are analyzed for each of the trajectory types.
In particular the injury severity score was highest in the roof vault group.
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.
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.
