Abstract

Child occupant safety has been evaluated in the European New Car Assessment Program (Euro NCAP) since 2003. Now child protection is being given more and more attention by car manufacturers. To keep up with global developments, China NCAP (CNCAP) has also started conducting child occupant safety assessment in high speed impact tests from Jan. 2010. SAIC Motor company has carried out a series of CNCAP and Euro NCAP tests using several brands of CRSs: 50kph full frontal rigid barrier (FRB) tests, 64kph offset deformable barrier (ODB) tests, and 50kph moving deformable barrier (MDB) side impact tests. In this paper, safety performance of different types of CRSs were compared on the basis of the test results. Child dummy kinematics and responses were influenced by both the vehicle crash pulse and the safety performance of the CRS itself. The injury assessment values for P3 on the barrier overlap side in the 64kph ODB tests were generally lower than those in the 50kph FRB tests. In front impact tests, the vehicle crash pulse had much more influence on the head acceleration than the chest acceleration, while the chest acceleration was more dependent on the CRS internal restraint system. In the side impact test, the P1.5 head of the struck side was contained within the boundary of the CRS shell during the entire crash event. The head accelerations for both P1.5 and P3 dummies in the side impact test were all much better than the threshold value indicated for better performance in Euro NCAP testing.
