Comparison of two child seats subjected to a regulatory side impact regarding biomechanical criteria associated to the newborn

摘要

The new Regulation 129 is a keystone in child safety as child restraint systems are now evaluated in side impact tests with Q-dummies. Research works have, nevertheless, shown that regulatory assessment criteria are not well correlated with head injuries. As a consequence, the present study aims to compare two child seat versions regarding biomechanical criteria associated to the anatomical head-neck system of the newborn. The main results show that the enhanced child seat leads to significative lower brain loading under regulatory test configuration.
