To provide a headrest which mitigates impact of a head during a rear collision and thereby adjusts a speed at which the head moves back into a forward direction and prevents excessive deformation of a stay.SOLUTION: When a head of an occupant collides with a headrest 14 at the time of a rear collision, a third support part 2002C of a stay 20 tilts toward a rear direction of a vehicle because of deformation of a deformation inducing part 2006. This mitigates impact of the head of the occupant at the time of the rear collision and is advantageous in adjusting a speed at which the head moves back into a forward direction due to repulsive force generated by the collision with the headrest 14. In addition, excessive deformation of the stay 20 can be prevented by restricting tilting of the stay 20 by way of a bracket 28, which is advantageous in surely mitigating the impact of the head of the occupant at the time of the rear collision.SELECTED DRAWING: Figure 3

    【課題】後突時に頭部の衝撃を緩和させることで、頭部が前方に戻る速度を調整するとともに、ステイの過度な変形を防止する。【解決手段】後突時に乗員の頭部がヘッドレスト14に衝突した際、変形誘発部2006の変形によりステイ20の第3支持部2002Cが車両後方へ傾斜する。そのため、後突時、乗員の頭部の衝撃を緩和させることで、頭部がヘッドレスト14との衝突による反発力により前方に戻る速度を調整する上で有利となる。また、ブラケット28によりステイ20の傾斜を規制することで、ステイ20の過度な変形を防止できる。そのため、後突時、乗員の頭部の衝撃を確実に緩和させる上で有利となる。【選択図】図3
