This study will show results of 762 car to pedestrian collisions, documented in ln-depth Investigations on the scene at the Medical University Hannover/ Germany. ln-depth Investigations are carried out in Hannover since 25 years by a team of technicians and physicians by order of the Federal Highway Research Institute (BASt). Deformation pattern of cars, description of injuries and contact points on the car and characteristics of special traces on the scene and on the vehicle are documented for analyzing injury mechanisms. A comprehensive reconstruction of motions of the pedestrian body is carried out and the collision speed is determined. The situation for the injuries are described in relation to collision speed.
The detailed impact situation of the head in the area of the windscreen was analyzed and the deformation patterns of the glass and the frame was compared to the injury pattern of the head.
It could be pointed out that most of all windscreen impacts with the head occurred to the lower half part of the screen and a very low number to the glass near or on the frame region. The injury severity of the head is not significantly higher in the frame region than in the middle-part of the screen.
In this study improvements for reducing the injury severity are postulated and a proposal for an optimized test procedure is described.
