Abstract
A vehicle headrest device capable of both securing the comfort of an occupant under normal conditions and enhancing the whiplash injury prevention effect, while enabling the headrest body to be made thinner. In this device, a dilatant pad formed from a material with dilatant characteristics is disposed at a front portion of a headrest body. The pad is soft in normal circumstances, and so the occupant's head can be softly supported by the headrest body. However, the pad instantly becomes hard when load from the occupant's head is imparted to the front portion of the headrest body such as during an impact to the rear face of a vehicle, suppressing rearward head movement. Moreover, a thinner headrest body can be achieved due to being able to dispense with a foam body disposed at the front portion of the headrest body to secure the comfort of the occupant.
