Submarining is a phenomenon in that the lap belt goes over the pelvis of the occupant during a frontal crash. It is known to be one of the causes of serious abdominal injuries for the belted occupant. The goal of the current study was to investigate the effect of both the belt geometry and dummy variations on the occurrence of submarining. A series of quasi-static belt-pull tests were performed to evaluate the influence of the parameters on the occurrence of the submarining. The main influencing factor of the submarining was the lap belt angle. The tear or wrinkle of the dummy clothing and torso angle relative to the pelvis also affected the propensity of the submarining. Therefore, these parameters need to be closely monitored to obtain repeatable test results.
Abstract
Submarining is a phenomenon in that the lap belt goes over the pelvis of the occupant during a frontal crash.

A series of quasi-static belt-pull tests were performed to evaluate the influence of the parameters on the occurrence of the submarining. The main influencing factor of the submarining was the lap belt angle. The tear or wrinkle of the dummy clothing and torso angle relative to the pelvis also affected the propensity of the submarining. Therefore, these parameters need to be closely monitored to obtain repeatable test results.
