Zusammenfassung:To improve a function of maintaining upper body posture of a seated occupant by allowing an upper part of a pelvis at a back side, of parts contacting a seat back of the seated occupant, to be supported by elasticity of the seat back and improve sitting comfort by making the other parts to follow a body shape of the seated occupant.SOLUTION: A vehicular seat back 12, which constitutes a backrest part of a vehicular seat 10, comprises a cushion material 40 arranged at the backrest part and a covering material 41 covering an outer surface of the cushion material 40. When areas which an upper part T1 of a pelvis at a back side of a seated occupant H seated on the vehicular seat 10 contacts are defined as pelvis-upper contacting areas 42 in the covering material 41, high elastic areas 50 in which elasticity is enhanced more than in the other areas are provided in the pelvis-upper contacting areas 42 of the backrest part (that is the seat back 12).SELECTED DRAWING: Figure 2 【課題】着座者のシートバックへの接触部分のうち、背面側骨盤上部をシートバックの弾性により支持して、着座者の上体姿勢維持機能の向上を図り、他の部分は着座者の体型に追従させて、座り心地の向上をも図る。【解決手段】この発明は、車両用シート10の背凭れ部を構成する車両用シートバック12であって、背凭れ部に配置されたクッション材40と、クッション材40の外表面を被覆する表皮材41とを備え、表皮材41における、車両用シート10に着座した着座者Hの背面側骨盤上部T1が当接する領域を骨盤上部当接領域42とすると、背凭れ部(即ちシートバック12)のうち、骨盤上部当接領域42には、他の領域と比べて弾性が高められた高弾性領域50が設けられている。【選択図】図2
