摘要： A headrest including: a headrest body that supports a head portion of an occupant; a pair of side frame sections that supports the headrest body, the side frame sections extending along a seat height direction and disposed at a separation from each other along a seat width direction; and an inclined wall portion that is provided between the side frame sections, that is inclined towards a seat front-rear direction front side with respect to the side frame sections such that a lower end portion of the inclined wall portion is positioned further to the seat front-rear direction front side than an upper end portion of the inclined wall portion, and that bears load acting on the headrest body from a seat front-rear direction rear side.

摘要： 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 (46) (including grommets (22)) 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 (46) (including the grommets (22)) 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 (46) including the grommets (22), thereby enabling the time until the headrest contacts the head of the occupant to be shortened with a simple configuration.
摘要翻译： 在后部碰撞的情况下头枕接触乘员头部的时间以简单的配置缩短。 在座椅装置中，将停留物（46）（包括索环（22））设置成朝向车辆前方的弯曲刚度低于朝向车辆后部的弯曲刚度。 因此，当在车辆后方碰撞的情况下头枕振荡时，头枕首先朝向车辆后方移动，然而头枕在短时间内改变方向，并开始向车辆前方移动。 此外，由于停留（46）（包括索环（22）），朝向车辆后方的弯曲刚性具有朝向车辆前方的较低的弯曲刚性，所以头枕朝向车辆前方具有大的位移。 因此可以缩短头枕接触乘员头部（H）的时间。 由于设置包括索环（22）的支柱（46）的弯曲刚度，头枕可以迅速地朝向乘员的头部（H）的位置移位，从而能够直到头枕接触乘员头部 以简单的配置缩短。
