Abstract

Contact between lower limbs of pedestrian and bumper of passenger car is the first impact position in the vehicle to pedestrian crashes. Based on the principles of anthropotomy, anthropometry, and the statistic of traffic crashes, the contact position relation between bumper of passenger car and lower limbs of pedestrian in China is analyzed. According to the classification statistics of the crashes involving pedestrian, the physical dimensions of vehicle and pedestrian are applied to analyze the position relation mentioned above, including lateral, anterior, and posterior of human body impacted by frontal body of car. Considering the changes of position of pedestrians, the proportions of different contact position relations under Chinese traffic status are obtained. Dimension scope of car bumper covers the whole area of knee joint of Chinese pedestrians, and the contact position between bumper and lower limbs is knee joint and upper leg part. For female, the injury possibility of upper legs is higher than male. The results can provide insights for pedestrian protection and crash simulation.
