Abstract

Whiplash injury/disorder is a common neck-injury in road traffic accidents. This paper introduces energy absorbing car-seat concepts which can reduce the risk of whiplash injuries. Computational multi-body models of a generic car seat and a biofidelic 50th-percentile male human model for rear impact are developed to assess the effectiveness of the proposed car-seat concepts. The numerical sled-test-simulations show that the proposed car-seat concepts can successfully mitigate whiplash injuries for a wide range of crash severity by utilising energy absorbing devices which can remain reusable after a rear-impact. A physical model of a proposed car-seat concept is built and tested to verift the computational models.
