Investigations on the Belt-to-Pelvis Interaction in Case of Submarining

Submarining is the common term for lap belt slip on the iliac spines of the pelvis. A research objective was to use both post mortem human subjects (PMHS) and dummies to compare the interaction between the lap belt and the pelvis. A second research objective was identification of pelvic lap belt hooking parameters, for which a hydraulic test device mimicking lap belt tension and kinematics in frontal car crashes was developed. The pelvis was firmly fixed on the test device and the belt anchorages were mobile. Researchers conducted fourteen tests on four PMHS and fifteen tests on the Hybrid III 95th percentile, Hybrid III 50th percentile, and THOR NT dummies. Belt anchorages experienced dynamic rotation while belt tension was constant. Belt angle relative to the pelvis was systematically greater for dummies than for PMHS in tests where submarining occurred. Greater submarining angle for both dummies and PMHS occurred with an increase in belt tension. Hybrid III dummies experienced significantly lower pelvic and abdominal stiffness than the PMHS and THOR NT dummy, which were similar.
