Six occupant restraint systems (both current production and prototype) were evaluated in terms of comfort and convenience by 30 subjects. Questions were asked concerning particular problem areas as well as overall system comparisons. A new paired comparison statistical procedure was developed that considers each subject as an independent control factor and, therefore, eliminated personal bias. The modified Seville was significantly better than the other systems. The modified Volare, standard Volare, and Impala rated in the upper to middle category. The Rabbit and Chevette ranked as the worst systems tested. Smoothness, repeatability, and comfortable tension in the shoulder belt retractor appeared to be the most important factors influencing comfort and convenience.
