To provide a headrest which can prevent whiplash of an occupant and contribute to miniaturization of a headrest body.SOLUTION: In a headrest 20, a headrest body 26 is supported on a headrest stay 22 connected to a top end part of a seat back 14. In a headrest body 26, a plate-like member 30 is arranged. The plate-like member 30 is formed in the plate shape and is arranged in the headrest body 26 in such a posture that the plate thickness direction is along the front-rear direction. When the vehicle is collided from its rear face, the plate-like member 30 is bent by being compressed in the direction orthogonal to the plate thickness direction by a compression part and a front surface of the headrest body 26 swells to the front side. Thereby, whiplash of an occupant can be prevented since the head of the occupant is supported by the headrest body 26 at an early stage. Also, since the plate-like member 30 is formed into the plate shape, the arrangement space of the plate-like member 30 in the headrest body 26 can be set to be thin in the front-rear direction.SELECTED DRAWING: Figure 2

    【課題】乗員の鞭打ちを防止可能で且つヘッドレスト本体の小型化に寄与するヘッドレストを得る。【解決手段】ヘッドレスト20では、シートバック14の上端部に連結されるヘッドレストステー22にヘッドレスト本体26が支持される。ヘッドレスト本体26内には、板状部材30が配置されている。板状部材30は、板状に形成され、板厚方向が前後方向に沿う姿勢でヘッドレスト本体26内に配置されている。車両が後面衝突した場合、板状部材30が圧縮部によって板厚方向と直交する方向に圧縮されて曲がることにより、ヘッドレスト本体26の前面が前方側へ膨出する。これにより、乗員の頭部がヘッドレスト本体26に早期に支持されるので、乗員の鞭打ちを防止することができる。しかも、板状部材30が上記のような板状に形成されているので、ヘッドレスト本体26内での板状部材30の配置スペースを前後方向に薄く設定することができる。【選択図】図2
