Abstract:

Misuse of child restraint system (CRS) is a common issue, although CRS can provide protection
only under correct use cases. This paper reported a survey on CRS misuse status among parents of children in
the Beijing area. The survey results show that CRS misuse rate in China is more than 70%, and CRS users have
little knowledge and awareness of misuse. Based on the CRS misuse data from the survey and from foreign
countries, sled tests were conducted for 8 types of common CRS misuse. Sled tests results illuminate that the
should-beltunder-armpit misuse type is the most significant impact on children safety among different misuse
types, because it can increase HIC15, the head injury criterion (HIC) in an interval of 15 ms, by 500%.

Key words: automobile passive safety, child restraint system (CRS), misuse, questionnaire survey, sled test
