Analysis of Injury Potential of Three-year-old Child Occupants Caused by Inappropriate Installation of Enhanced Child Restraint System with Top Tether in Frontal Crash Accidents

Objective: Frontal crash accidents remain a significant factor in causing the preventable injury and fatality for child occupants aged 3 China. Despite increased public awareness utilization of restraint system (CRS), inappropriate installations still exist lead to potential result injuries head, thorax abdomen regions occupants, especially when it comes enhanced (ECRS) with top tether. The current study focuses on influence tether upon safety performance ECRS dynamic tests different set-ups explores relationship between installation frontal crash. Methods: A testing scheme including 4 was devised ascertain extent which affected accelerations thorax, abdominal penetration head displacements. Different kinds acceleration curves were employed conduct simulate real status situation CRS installed without respectively. Parameters accelerations, penetrations, displacements measured analyze quantitatively under conditions. Results: use found better than that either normal condition or extreme condition. test using defined by regulations, P3 manikin connected anchor point revealed results all met requirements. While same kind, not connected, parameters displayed sample worse former one. As more severe at will, obvious could affect function greatly, functional failure damages occurred partly qualified even Conclusions: Inappropriate such as omitting step connecting cause fatalities accidents. Effective measures should be taken minimize chances ECRS.
