Car seat design to improve rear-impact protection

This study presents car seat concepts which are designed to mitigate whiplash injuries through coordinated motion of seat components for a wide range of crash severities. In order to evaluate the effectiveness of the proposed car seat concepts, computational multibody models of a generic car seat and a biofidelic 50th-percentile male human model for rear impact are developed. A number of car seat concepts are shown to reduce the risk of whiplash injuries by utilizing head restraint support and energy-absorbing features, which remain reusable after impact.
