| Abstract(E) | In frontal impacts, rearward pelvic rotation can cause the lap belt to slip off the pelvis, increasing the risk of submarining. To investigate this phenomenon, finite element simulations of rear-seat sled tests under frontal impact conditions were conducted to analyze the pelvic rotation that occurs under lap belt restraint. The moment time histories around the pelvic center of gravity were compared using human body models (THUMS) of an average male and a small female, clarifying the characteristics of the rotational behavior attributed to pelvic shape. |
