Front-row occupant protection in frontal crashes has benefited from restraint system development and vehicle crashworthiness improvements which have been driven partly by manufacturers’ efforts to improve vehicle scores in consumer metric tests. Until recently, occupants in the rear seat have not been considered in most consumer metric tests. As a result, a rear occupant evaluation has been introduced in Europe as a part of the EuroNCAP. Occupant protection performance in the rear seat needs to be evaluated in order to perform well in this newly introduced market requirement. This study investigates the potential benefits of seat belt pretensioners and load limiters in the rear seat for the new EuroNCAP condition. A series of sled tests were conducted following the new EuroNCAP protocol for a 50 km/h full width rigid barrier test. A Hybrid III 5th percentile female (AF5) dummy was seated in the rear seat of a sled buck representative of a smallsized vehicle. A mathematical simulation study of rear seat restraint parameters was first performed to assess chest deflection, head excursion trend and neck injury using different belt load limiters and pretensioning stroke with the Hybrid III 5th percentile female dummy. The results suggest that the belt pretensioner and load-limiter studied here may improve performance to rear seat occupants in the EuroNCAP condition, although more study is needed to evaluate these restraints in other crash scenarios. This study is limited to the Hybrid III 5th percentile female (AF5) dummy in this load case. Restraint performance for larger and smaller occupants also needs to be considered.
