Sensitivity of Thor and Hybrid Iii Dummy Upper and Lower Neck Forces and Moments to Belt Systems in Frontal Impact

The objective of this paper was to determine the head-neck biomechanics with a focus on lower neck injury metrics using different anthropomorphic test devices (dummies). Specifically, the paper conducted sled tests by positioning the mid- and large-size Hybrid III and Thor dummies in a custom designed frontal impact buck that consisted of a rigid seat, an adjustable head restraint, and an adjustable knee bolster. The paper conducted tests at low, medium, and high change in velocities using three restraint conditions. Peak upper neck moments were more sensitive than peak upper neck forces for all dummies. Moments in the Thor dummy were more sensitive than the moments in the mid-size Hybrid III dummy at both the upper and lower necks. This paper presents restraint-based data and addresses biofidelity differences between dummies as well as dummies of the same family with differing size. Such data are critical in off-center and small overlap frontal crashes where an airbag may not offer the most optimum protection as well as for rear seat occupants wherein frontal impact airbags do not exist.
