Kinematic Comparison of the Hybrid III and Q-Series Pediatric ATDs to Pediatric Volunteers in Low-Speed Frontal Crashes.

Kinematic Comparison of the Hybrid III and Q-Series Pediatric ATDs to Pediatric Volunteers in Low-Speed Frontal Crashes. Ann Adv Automot Med. 2012;56:285-98 Authors: Seacrist T, Samuels M, García-España JF, Arbogast KB, Mathews EA, Balasubramanian S, Maltese MR, Longhitano D, St Lawrence S Abstract Previous research has suggested that the rigid pediatric ATD spine may not adequately represent the relatively mobile, multi-segmented spine of the child and thus may lead to important differences in the head trajectory of the ATD relative to a human. Recently we compared the responses of size-matched child volunteers to the Hybrid III 6-year-old ATD in low-speed frontal sled tests, illustrating differences in head, spinal, and pelvic kinematics as well as seating environment reaction loads. This paper expands this line of work to include comparisons between size-matched restrained child volunteers to the Hybrid III 10-year-old and the Q-series 6 and 10-year-old ATDs tested in the same low speed frontal environment. A 3-D near-infrared video target tracking system quantified the position of markers on the ATDs and volunteers(head top, nasion, external auditory meatus, C4, T1, and pelvis). Angular velocity of the head, seat belt forces, and reaction loads on the seat pan and foot rest were also measured. The Hybrid III 6 and Q6 exhibited significantly greater belt reaction loads compared to the pediatric volunteers, which exhibited greate...
