Abstract:

Children's safety seat or named child restraint system (CRS) can effectively reduce the casualty rate of the children in traffic accidents without misuses and defects. The authors made questionnaire survey on the use of CRSs in China, investigated the assessment system of ease of use, and comparatively analyzed
the situation of usage rate and the misuse, the assessment system of ease of use and the recall data for CRSs in 2010-2017 in China and the US. The results show that the usage rate of CRSs in five large cities in China accounts for only 20.9%, which is far lower than that of the US, and the users' misuse rate in China is over 80%, which is also higher than that in the US. The assessment method of ease of use of CRSs in China is suitable for the market and the users?? habits in China. The number of recalled defect CRSs in the US is far greater than that in China, and the recall supervisions of defect CRSs are more severe than that in China. Therefore, the authors proposed some suggestions that Chinese government should strengthen the legislation and the customer propagation for CRSs, while whole CRS industry should complete the assessment of ease of use and strengthen the supervisions for defect CRS product recall to improve the product quality and to protect the safety of children in vehicles.

Key words: child restraint system (CRS), defect product recall, assessment of ease of use, comparative analysis
