Three-Point Restraint System Design Considerations for Reducing Vertical Occupant Excursion in Rollover Environments

Abstract

<div class="htmlview paragraph">In this study we continue and build upon previous research conducted with various production three-point restraint systems; studying resulting vertical excursion on restrained inverted occupants. Vertical excursions will be reported for various sized occupants restrained by both production vehicle belt systems as well as systems incorporating alternative designs. Vertical excursions have been reduced by an average of 77% with optimized belt geometry combined with belt pretensioning.</div>
