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.

There is provided a headrest device including: a headrest main body that is provided at an upper end portion of a seat back of a seat in which a passenger sits; a pressure/flexure detecting section that is provided at a vehicle front side of the seat back; a headrest moving section; and a control section that estimates a current back-set, that is a distance between a head portion of a passenger and the headrest main body in a horizontal direction, on the basis of at least one of pressure and flexure detected by the pressure/flexure detecting section and a predetermined relationship between back-set and the at least one of pressure and flexure, and controls the headrest moving section to move the headrest main body such that the back-set becomes a predetermined amount.

A headrest device comprises a headrest body which includes a headrest rear portion supported with respect to a seatback of a seat on which a passenger of a vehicle sits, and a headrest front portion that is movable within a predetermined range from a fully closed position that is closest to the headrest rear portion to a fully open position that is farthest from the headrest rear portion; a detection unit which detects a running state or an operation state of the vehicle; a prediction unit which predicts a possibility of a rear vehicle collision with the vehicle on the basis of the running state or the operation state of the vehicle detected by detection unit; and a control unit which controls, in a case in which the possibility of the rear vehicle collision is predicted by the prediction unit, movement of a position of the headrest front portion so that a backset becomes smaller than a backset at the time of the prediction, the backset being a horizontal distance between the headrest front portion and a head of the vehicle passenger.
