This paper summarizes the results of tests conducted with anesthetized animals that were exposed to a wide range of passenger inflatable restraint cushion forces for a variety of impact sled–simulated accident conditions. The test configurations and inflatable restraint system concepts were selected to produce a broad spectrum of injury types and severities to the major organs of the head, neck and torso of the animals. These data were needed to interpret the significance of the response of an instrumented child dummy that was being used to evaluate child injury potential of the passenger inflatable restraint system being developed by General Motors Corporation. Injuries ranging from no injury to fatal were observed for the head, neck and abdomen regions. Thoracic injuries ranged from no injury to critical, survival uncertain. Graphs are presented that show association between the severity of the animal injuries by body region and selected measured animal responses and restraint system-accident characteristics. Caution must be used in interpreting the significance of these injuries relative to the expected performance of passenger inflatable restraint systems since aggressive restraint system concepts and accident conditions were selected for some tests in order to produced severe injuries.
