Comparison of WorldSID to PMHS kinematics in far-side impact
Paper i proceeding, 2018

Far-side impacts represent 9.5% of all automobile crashes and 8.3% of all MAIS3+ injuries. This type of event generates loads that challenge current restraint systems by setting the occupant on an inward motion. This complex motion, influenced by a number of restraint and impact parameters, often results in a loss of shoulder-to-belt contact. Reducing the negative outcomes of this type of crash requires an ATD capable of correctly representing the kinematics and sensitivity to restraint and impact parameters. The WorldSID is the most advanced ATD for injury evaluation in near-side crashes. However, its suitability for far-side scenarios still needs to be evaluated. This study performed a parametric evaluation of the effect of restraint and impact parameters on WorldSID kinematics. A total of 19 tests in six different test configurations were conducted, matching previously published PMHS tests. The ATD motion was tracked with a 3D high-speed motion-capture system. The parameters varied were: the impact severity and direction; D-ring position; pelvic restraint; and seat belt pretensioning. The ATD response and sensitivity to parameters were evaluated and compared to previously published PMHS data. The results show discrepancies in shoulder-belt engagement, head and torso kinematics and sensitivity to initial conditions.
