摘要:

儿童约束系统误(CRS)使用是一个普遍存在的问题,而儿童约束系统只有在正确使用的情况
下才能充分发挥其保护作用。对儿童约束系统的误使用情况,本文报告了在北京地区对儿童家长进行
的问卷调研。中国儿童安全座椅误用率在70% 以上,儿童安全座椅使用者对于误使用概念模糊且意
识薄弱。基于这些调研数据以及国外误使用研究数据,针对8 种常见的儿童安全座椅误用模式,进
行了台车碰撞模拟试验研究。试验结果表明:儿童座椅的误使用对儿童安全性的影响显著,其中儿童
肩带在儿童腋下的误使用模式,是对安全性影响最大的误使用模式,它可导致HIC15(15 ms 间隔的
头部伤害指标)增加500%。

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
