To provide a vehicular seat back which inhibits change of an attitude of an occupant during turning without deteriorating the ride quality.SOLUTION: A vehicular seat back 11 includes a pad 3 and a pressure receiving member 4. The pad has: a foam member 31 which elastically deforms; and a reinforcement member 32 which is applied to a rear surface of the foam member and reinforces the foam member. The pressure receiving member has: a base part 69 located at a center part as seen in a width direction of the seat back; and multiple side pieces 60 which respectively extend outward in the width direction from both sides of the base part. The pad has reinforcement reduction parts 321 which weaken reinforcement of the reinforcement member at positions which overlap with parts of the side pieces when viewed from a direction orthogonal to a surface of the seat back.SELECTED DRAWING: Figure 2
【課題】乗り心地を悪化させずに、旋回時の乗員の姿勢の変化を抑制する。【解決手段】車両用シートバック11は、パッド3と、受圧部材4と、を備え、パッドは、弾性変形する発泡部材31と、発泡部材の後面に貼り付けられかつ、発泡部材を補強する補強部材32と、を有し、受圧部材は、シートバックの幅方向の中央部に位置する基部69と、基部の両側それぞれから、幅方向の外方へ延びる複数の側片60とを有し、パッドは、シートバックの面に直交する方向から見て一部の側片と重なる位置に、補強部材の補強を低下させる補強低下部321を有している。【選択図】図2
