Abstract

Recent studies have discussed the relevance of injuries to the thorax in vehicle vs pedestrian accidents. The present study reports preliminary investigations on effect of vehicle type, impact location, pedestrian orientation, pedestrian leg position for the walking posture and effect of upper extremity interaction with the vehicle, on the injury to the thorax and specifically the rib fracture. Detailed finite element models of the production vehicles and Human Body Model (HBM) representing 50th percentile American Male were used in the study. The results indicate that injury to the thorax is influenced from several factors both related to the vehicle and pedestrian. Further investigations are needed to comprehensively understand the parameters influencing the injuries and develop strategies for injury prevention.
