“…Finally, results were based on the assumption that occupants were in contact with the roof or roof rail prior to a roof impact, which agreed with findings of Gloeckner et al (2007) and Padmanaban et al (2005).…”

“…vii) The occupant's head is in contact with the roof rail at the time of roof-to-ground impact (Padmanaban et al 2005, Gloeckner et al 2007). viii) No sliding or rebound between head and roof is assumed.…”

“…In the current study, the injury risk was evaluated indirectly by the local ∆V near the head location. The injury risk was assumed to be directly related to local impact severity (∆V), as the occupant's head is in contact with the roof rail at the time of roof-to-ground impact in high-speed rollovers (Padmanaban et al 2005, Gloeckner et al 2007). A relationship between head peak velocity and neck injury risk was previously described by , while the head injury risk is related to head translational or angular acceleration, which in turn increases with local ∆V.…”

ABSTRACTA previously developed two-dimensional model of a vehicle in a lateral roll ) was used in this study to analytically evaluate the effect of vehicle roll angle and roll velocity on roof-impact ∆V and consequent occupant injury mechanism and risk. Both occupants adjacent to (near-side) and remote from (far-side) the rollover's leading side were evaluated. Injury evaluation was limited to head and neck/spinal injuries.The vehicle's roll angle at the time of roof-impact dramatically affected the local ∆V at the point of head-toroof contact.
