Problems solved by technology

[0003] However, for a headrest inclined toward the front of the vehicle at a large inclination angle, when the occupant's head contacts the rear of the headrest, the component of force acting on the headrest in the downward direction of the vehicle is relatively large

Abstract

A headrest includes: a headrest body supporting the head of an occupant; a pair of side frame parts supporting the headrest body, the side frame parts being along a seat height direction extending and arranged to be separated from each other in the seat width direction; and an inclined wall portion provided between the side frame portions, the inclined wall portion facing the front side in the seat front-rear direction with respect to the side frame portions inclined so that the lower end of the inclined wall is closer to the front side in the front-rear direction of the seat than the upper end of the inclined wall, and the inclined wall receives an action on the headrest body from the rear side in the front-rear direction of the seat load.

Description

technical field [0001] The invention relates to a headrest and a vehicle seat provided with the headrest. Background technique [0002] Vehicle seats are known which are provided with a headrest for supporting the head of an occupant. In the case of various of these vehicle seats, there is a possibility that during a frontal collision (vehicle frontal collision), the head of an occupant sitting in the rear seat of the vehicle seat moves toward the front of the vehicle due to inertia, The head may thus come into contact with the rear of the headrest of the vehicle seat. In this case, for the headrest inclined toward the front of the vehicle at a small inclination angle, when the occupant's head contacts the rear of the headrest, the component of force acting on the headrest toward the front of the vehicle is relatively opposite. Larger, and thus the seat back supporting the headrest turns towards the front of the vehicle, thereby absorbing impacts to the headrest. Therefor...
