MULTI-DISCIPLINARY ACCIDENT INVESTIGATIONS - SPECIAL STUDY OF ACTIVE AND PASSIVE RESTRAINT SYSTEMS IN 1973-1976 MODEL YEAR VEHICLES. VOLUME 1. RESTRAINT SYSTEMS EFFECTIVENESS PROGRAM

Volume 1 contains the methodology, findings, conclusions, and recommendations for the study. Field data were collected from April 1, 1974 to December 31, 1975. The primary objective of the restraint system evaluation program was to estimate the true injury-reducing effect of lapbelts and lap and shoulder belts. In the Texas study area, 12.2 percent of the unrestrained occupants, 6.2 percent of those wearing lapbelts only, and 4.8 percent of those wearing both lap and shoulder belts sustained injuries. SwRI found that lapbelts were 49.7 percent more effective in reducing injuries than no belts, lap and shoulder belts were 61.1 percent more effective in such cases, and lap and shoulder belts were 22.6 percent more effective than only lapbelts. The study includes: Volume 2-In-Depth Investigations of ACRS, Control Group, and Schoolbus Accidents; Volume 3-Data Summaries for Restraint System Effectiveness Program; Volume 4-Forms, Codebooks, and Computer Programs.
