• Empirical assessment of seat belt effectiveness and injury outcomes across crashes emerges as a central safety science pattern in 1972-1977, with quantitative estimates of belt effectiveness, injury reduction, and biomechanical consequences across frontal, head-on, and rollover scenarios [1], [6], [11], [12], [17], [18], [19].

• Socio-psychological and policy dimensions shape belt adoption, including factors influencing use, beliefs and attitudes, and situational factors affecting compliance and health policy [2], [9], [13].

• Design, engineering, and injury mechanism as determinants of belt-related risk, spanning steering/instrument panel effects, belt system effectiveness, belt failures, and related injury patterns [5], [7], [14], [15], [17], [19].

• Accident causation, system safety, and risk analysis underpin road safety research, evidenced in accident-based error analyses, rollover/injury causation studies, and epidemiological accident studies [8], [10], [16], [20].
