Responses of Hybrid III and Q3 Dummies in Various CRSs Tested using ECE R44 Impact Conditions

Abstract

In this study, sled tests were carried out using Hybrid III 3YO and Q3 dummies seated in impact shield CRSs and 5-point harness CRSs under the impact conditions specified in ECE R44. The Hybrid III 3YO and Q3 kinematic behavior and injury measures were compared for these various types of CRSs. The global dummy kinematic behavior was comparable between the Hybrid III 3YO and Q3 dummies and was different between 5-point harness CRSs and impact shield CRSs. In the impact shield CRSs, the chest deflection was large and depended on the shield structure.
