Abstract:Pedestrian knee ligament injuries and lower leg fractures are the most frequent and among the most debilitating long-term injuries in motor vehicle crashes. Global Technical Regulation No. 9, Pedestrian Safety, has been adopted by the international community to mitigate these pedestrian injuries through improved vehicle bumper systems. The current UN GTR includes the flexible pedestrian legform impactor (FlexPLI), which simulates the lower limb of a pedestrian and is the device widely used in global New Car Assessment Programs to assess the protection level of the front-end structures of vehicles. The objective of this study was to perform a preliminary evaluation of the upper body part addition to the FlexPLI (FlexPLI-UBM) and the advanced pedestrian legform impactor. Test results from the advanced legforms used in this evaluation were compared to each other and to the current FlexPLI at matched impact locations.
