Abstract
The time until a headrest contacts the head of an occupant in the event of a rear collision is shortened with a simple configuration. In a seat device, a stay () (including grommets ()) is set with bending rigidity towards the vehicle front lower than the bending rigidity towards the vehicle rear. Accordingly, when the headrest oscillates in the event of a vehicle rear collision, the headrest is initially displaced towards the vehicle rear, however the headrest changes direction in a short time and begins to be displaced towards the vehicle front. Moreover, there is a large displacement of the headrest towards the vehicle front since the stay () (including the grommets ()) has a lower bending rigidity towards the vehicle front than the bending rigidity towards the vehicle rear. The time until the headrest contacts the head (H) of the occupant can accordingly be shortened. The headrest can be promptly displaced towards the side of the head (H) of the occupant due to setting the bending rigidity of the stay () including the grommets (), thereby enabling the time until the headrest contacts the head of the occupant to be shortened with a simple configuration.
