To describe several aspects of booster seat use and misuse in a sample of children attending child safety seat clinics.
Booster seat practices were assessed at 76 child safety seat clinics held between April 1997 and January 1999 in Pennsylvania and southern New Jersey. At each assessment, a child passenger safety team evaluated the booster seat and identified modes of misuse.
Altogether 227 booster seats were observed. Sixty eight per cent (68%) of shield boosters and 20% of belt positioning boosters were misused. Thirty two per cent of the children using a shield booster weighed more than 40 lb (18.1 kg); 68% of children in shield boosters and 63% in belt positioning boosters weighed less than 40 lb.
This study identified a relatively high rate of booster seat misuse. Shield boosters were more likely to be misused than belt positioning booster seats. Significant numbers of children weighing more than 40 lb were using possibly dangerous shield boosters. The majority of children in this study were less than 40 lb. In this weight range, a convertible child restraint system provides better protection than a booster seat. Booster seat use should only be initiated once the child has completely outgrown their convertible child restraint system.
描述在参加儿童安全座椅诊所的儿童样本中增高座椅使用和误用的几个方面。
1997年4月至1999年1月期间在宾夕法尼亚州和新泽西州南部举办的76场儿童安全座椅诊所中对增高座椅使用情况进行评估。每次评估时，一个儿童乘客安全小组评估增高座椅并确定误用模式。
共观察到227个增高座椅。68%的护盾式增高座椅和20%的定位安全带式增高座椅被误用。使用护盾式增高座椅的儿童中，32%体重超过40磅（18.1千克）；使用护盾式增高座椅的儿童中68%以及使用定位安全带式增高座椅的儿童中63%体重不足40磅。
本研究发现增高座椅误用率相对较高。护盾式增高座椅比定位安全带式增高座椅更易被误用。大量体重超过40磅的儿童在使用可能存在危险的护盾式增高座椅。本研究中的大多数儿童体重不足40磅。在此体重范围内，可转换儿童约束系统比增高座椅提供更好的保护。增高座椅的使用应仅在儿童完全不再适用其可转换儿童约束系统后开始。
