Human Subject Experiments In Occupant Response To Rollover With Reduced Headroom

This paper describes some human subject experiments in occupant response to rollover with reduced headroom. The results suggest that with a nominal 10 cm of head room, 7.5 to 15 cm of torso excursion in production belts and more than 15 cm of roof intrusion, serious neck injury is likely. Brain damage/head injury is more likely from a combination of roof rail crush and high change of angular roll rate.
