In this study, a state-of-the-art whiplash-mitigating passive seat is retrofitted with a pro-active head-restraint, an auxiliary damper at the recliner and a firmer layer of seat back suspension and foam in the seat back structure so as to provide improved neck protection for rear-end impacts having delta-V's between 13 km/h and 35 km/h. The retrofitted seat proposed in this study is designed by using a biofidelic occupant model which is a 50th percentile male. Virtual sled tests are performed in accordance with the EuroNCAP dynamic whiplash assessment protocol. The crash energy to be absorbed by the seat components are distributed to provide balanced protection for all severities. The proposed forward-facing retrofitted seat earns maximum points from the EuroNCAP whiplash rating even for a rear-end impact having 35 km/h of delta-V. This paper draws attention to designing seats that can withstand very high severity rear-end impacts and provide sufficient neck protection to limit whiplash associated disorders considerably.
