Abstract：
BACKGROUND: Seat belt marks are seen frequently on occupants after motor vehicle accidents. Over the years, the clinical significance of these marks has changed as restraint systems have evolved. With modern restraint systems, signs of a compromised occupant-restraint relationship are an important and easily identified bedside finding.
OBJECTIVE: We sought to learn to recognize seat belt marks that demonstrate an abnormal occupant-restraint system relationship and to cultivate an understanding of significant soft tissue biomechanical loading associated with marks caused by a compromised occupant-restraint relationship.
CONCLUSIONS: A review of case studies from the literature combined with forensic work demonstrate a strong correlation between significant injury and improper seatbelt use. When evidence of a compromised occupant-restraint relationship exists, incorporating computed tomography angiography and observation may be clinically indicated.
CONCLUSIONS: The recognition of seat belt marks made by a compromised occupant-restraint relationship is an important finding that allows risk stratification of the patient at the bedside. Further investigation with a prospective trial at a trauma center is warranted.

摘要：
背景：机动车事故发生后，乘员身上经常出现安全带标记。多年来,随着约束系统的发展，这些标记的临床意义发生了变化。有了现代约束系统，乘员-约束关系受损的迹象是一个重要且易于识别的床边发现。
目的：我们试图学习识别表现出异常乘员约束系统关系的安全带标记，并培养对与受损乘员约束关系引起的标记相关的显著软组织生物力学负荷的理解。
结论：对文献中的案例研究与法医学工作相结合的回顾表明，重大伤害与不当使用安全带之间存在很强的相关性。当存在乘员-约束关系受损的证据时，合并计算机断层扫描血管造影和观察可能是临床指征。
结论：识别由乘员约束关系受损造成的安全带标记是一项重要发现，可以在床边对患者进行风险分层。有必要在创伤中心进行前瞻性试验进行进一步调查。
