A review of the biomechanical and epidemiological literature on abdomen injury in motor-vehicle crashes was performed. Results of this review demonstrate that (1) there are limited data on abdomen injuries in real-world crashes of newer model airbag-equipped vehicles, (2) there are insufficient useful data on the force-deflection characteristics of the abdomen under loading conditions that represent those that occur to near-side occupants in T-type side impacts, (3) data are needed on the response of the abdomen to lap-belt loading using realistic belt geometry and loading conditions, and (4) data are needed on the dynamic response of spleen tissue and on failure criteria for spleen and liver tissue. To address the first identified need, analyses of the NASS and CIREN datasets were performed to determine how abdomen injuries occur in frontal and side crashes of airbag-equipped vehicles when seatbelt use is high. |
