Reliability Study of Automatic and Manual Restraint Systems. Volume 1

摘要

Evaluation of the reliability of automatic seat belt restraint systems on the 1975-1980 Volkswagen Rabbit, 1980 Chevrolet Chevette, and some 1980 Toyota Corona's is presented. The reliability of manual seat belt systems employed on these vehicles is also evaluated for comparison. Effects of system age and use, determined by acquisition and experimental testing of new and used systems, (from 4 geographic areas) with known user histories, is also reported. A comprehensive statistical model for seat belt reliability evaluation using data obtained through experimental testing and vehicle Federal Motor Vehicle Safety Standard (FMVSS) compliance testing is presented. User reports of restraint system difficulties, obtained in contacts with over 1500 users, are tabled, and recommendations for further research offered.
