Abstract: Wearing a soft headrest can change the seat's protective effect in a rear-end collision, but little research has been done on whiplash performance when wearing a soft headrest. In order to explore the role of soft headrest in rear-end collision accident, a comparative whiplash experiment is designed and completed about two conditions of wearing soft headrest and not wearing soft headrest. The results show that the soft headrest can make the dummy's head touch the seat earlier, support and buffer the head movement of the dummy, slow down the violent degree of the head swing backward, and reduce the damage of all parts of the dummy, the peak value of neck injury is significantly reduced, and the whiplash score is improved. As a kind of pre-research data accumulation of rear-end accident, the research results will serve for the revision of the whiplash regulations.
