Prior authors have suggested that when occupant ejection occurs in association with a seat belt failure, entanglement of the outboard upper extremity (OUE) with the retracting shoulder belt will invariably occur, leaving injury pattern evidence of belt use. In the present investigation, the authors assessed this theory using data accessed from the NASS-CDS for ejected front seat occupants of passenger vehicles. Logistic regression models were used to assess the associations between seat belt failure status and injuries. Injury types associated with seat belt failure were significant OUE and head injuries (OR = 3.87, [95% CI 1.2, 13.0] and 3.1, [95% CI 1.0, 9.7], respectively). The two injury types were found to be a predictor of seat belt use and subsequent failure only if combined with a high (≥0.8) precrash probability of belt use. The injury pattern associated with a seat belt failure-related ejection has limited use in the forensic investigation of crash-related ejections.
先前的作者曾提出，当乘员在安全带失效时被弹出车外，外侧上肢（OUE）与收缩的肩部安全带缠结将不可避免地发生，从而留下使用安全带的损伤模式证据。在本研究中，作者使用从国家汽车抽样系统 - 碰撞数据系统（NASS - CDS）获取的数据，对乘用车前排被弹出乘员的这一理论进行了评估。逻辑回归模型用于评估安全带失效状态与损伤之间的关联。与安全带失效相关的损伤类型主要是外侧上肢和头部损伤（优势比分别为3.87，[95%置信区间1.2，13.0]和3.1，[95%置信区间1.0，9.7]）。仅当与高（≥0.8）的碰撞前安全带使用概率相结合时，这两种损伤类型才被发现是安全带使用及随后失效的预测指标。与安全带失效相关的弹出所导致的损伤模式在与碰撞相关的弹出事故的法医调查中用途有限。
