Abstract
In this paper, thoracic and abdominal injury of motor vehicle belted occupant’s in frontal impact was analyzed based on in-depth accident sampling and investigation with medical and engineering network data. A total of 28 patients with AIS 2+ injury data was collected. We analyzed the relationships between frequency distribution of chest and abdominal injury and injury source, vehicle equivalent barrier speed(EBS), age effect. The results show that rib/sternum injury, lung injury and mesentery injury were occurred frequently belted occupant’s in frontal impact. It found that chest injury were occurred at EBS 25 km/h, abdominal injury was occurred at EBS 35 km/h.
