Matched-Pair Rollover Impacts of Rollcaged and Production Roof Cars Using the Controlled Rollover Impact System (CRIS)

Abstract

<div class="section abstract"><div class="htmlview paragraph">Three rollcaged and three production roof vehicles were exposed to matched-pair rollover impacts using the Controlled Rollover Impact System (CRIS). The roof-to-ground contacts were representative of severe impacts in previous rollover testing and real world rollovers. The seat belted dummies measured nearly identical head impacts and neck loads with or without the rollcage, despite significant roof crush in the production roof vehicles. Roof crush had no measurable influence on the severity of the head accelerations and neck loads.</div></div>
