Predictive Technique for Seat Belt Submarining Injury by Triaxial Iliac Load Cell

Article of Honda R&D Technical Review Vol.33 No.1

Summary

Submarining is one of the confirmation items in the frontal crash test, and if signs of submarining can be grasped with a single crash test, it will contribute to increasing the development efficiency of crash safety performance. This study created a prototype of a triaxial iliac load cell for an anthropomorphic test device and devised a method for calculating the position change of the acting point of the seat belt restraint load applied to the front end of the ilium, as a sign of submarining. In frontal crash sled tests that intentionally generated submarining, the acting point of the load applied to the ilium was observed to move upward from the front end of the ilium in the time zone before submarining occurred. As a result, this enabled to detect the signs prior to the occurrence of submarining.
