Pedestrian sustain very frequently injuries to their legs. These injuries are related to the contact with vehicle front end and may have long term consequences.
Taking into account biomecanics of the leg mechanisms injuries a deformable instrumented mechanical leg was designed.
The purpose of this mechanical leg is to predict the risk of leg injuries for a pedestrian, on the basis of the values of parameters recorded during a test.
This paper will discuss the biofidelity of the mechanical leg, its capability to separate the risk of injuries corresponding to different mechanisms and show with comparative tests the possibility of the device to select technical solutions allowing to optimise the protection of pedestrians against leg injuries.
