Driver Stature, Injuries and Airbag Deployments-Analysis of Umtri Crash Investigations
Published October 05, 1998 by Association for the Advancement of Automotive Medicine in United States
At the University of Michigan Transportation Research Institute (UMTRI), 784 crashes involving steering wheel airbag deployments have been investigated in detail (as of 3/1/98). A subset of only the frontal crashes, in which the steering wheel airbag deployed and driver stature was known, was formed (654 drivers). The vast majority of all drivers were lap-shoulder belted. Of these drivers, 70% sustained no injuries or an AIS-1 level injury. In these 654 crashes there were 204 "short'''' stature drivers, 165 cm or less in height (32% of all drivers). There were 40 of these with injuries at the MAIS-2 level and 15 who survived with an MAIS injury level of 3 or 4. Details of the injury locations and contacts are presented. Data on the taller drivers (450) were similarly tabulated. Of the taller drivers (≥ 168 cm), 74% had a MAIS-0 or 1 level injury. Of taller drivers with the MAIS-3, 4 or 5 injuries, the majority (67%) had such injuries unrelated to the deployment of the airbag. Of all the MAIS-2+ injured drivers, short or tall, 60% had such injuries unrelated to airbag deployments. The lower extremity was the body area most often involved, followed by the brain and upper extremity injuries.
