Ejection Mitigation Using Advanced Glazing: Status Report 2

摘要

In response to the National Highway Traffic Safety Administration (NHTSA)211u001eAuthorization Act of 1991 and ongoing research into rollover and ejection 211u001emitigation, NHTSA initiated a research program concerning occupant protection in 211u001emotor vehicle rollover crashes. NHTSA is addressing this occupant protection 211u001eissue from two perspectives-preventing a rollover from occurring and protecting 211u001evehicle occupants during a rollover, including reducing the likelihood of 211u001eejections. Almost 60 percent of rollover fatalities occur in the 10 percent of 211u001erollovers involving either complete or partial ejection of vehicle occupants. 211u001eOccupant ejections occur either through structural failures, such as door 211u001eopenings, or through window openings. NHTSA is evaluating the potential of 211u001eimproved door latches, side head air bags, and advanced glazing systems (an 211u001eautomotive industry term for transparent openings) to reduce occupant ejection. 211u001eThis report evaluates the progress of advanced glazing research since NHTSA 211u001eissued its November 1995 report on occupant protection research to mitigate 211u001eejection through window openings.
