The aim of the study is to determine the impact tolerance of the human pelvis. Results are considered of 36 impact tests against the pelvis of 10 cadavers in order to study the injury mechanism in lateral impact collisions. Pelvic fracture is a typical lesion sustained by the occupant of a vehicle involved in a lateral impact collision when seated on the impact side. Although not generally severe by itself, such injuries are often associated with severe abdominal lesions. A study of injury mechanisms in lateral impact collisions shows two ways of ensuring better occupant protection. The first is by decreasing impact intrusion to reduce contact velocity and secondly by absorbing the shock of occupants against the inner door at pelvis and thorax levels. From the results injury criteria are proposed to characterise the risk of pelvic fracture. The covering abstract for the proceedings is IRRD 261492.
