In the case of collision with high bumper vehicles, it is anticipated that the impactors which simulate only the lower limb of a pedestrian (such as the Flexible pedestrian legform impactor and the EEVC legform impactor) cannot evaluate the probability of knee and leg injuries appropriately. It is because they cannot simulate the influence of the pedestrian upper body. However, the test method which represents the influence of the upper body based on the analysis of the mechanism has not been developed. In this study, we performed a detailed FEM analysis about the influence of the upper body on knee and leg injuries. As a result, it turned out that the upper body affects the probability of knee and leg injuries significantly. In addition, in the case of the collisions with high bumper vehicles, the influence of the upper body was found to be different from that in the case of collisions with low-medium bumper vehicles.
