To provide a vehicle seat base material that has proper cushioning properties (comfort to sit on) and that can inhibit a submarine phenomenon when an impact is generated due to vehicular crash, sudden braking and the like, and a vehicle seat.SOLUTION: In a vehicle seat 10 in which a cushion material 21 is overlaid on a vehicle seat base material 11, the vehicle seat base material 11 comprises a front-side part 13 for being pressurized by the back side of a seated person's knee, and a rear-side part 15 for being pressurized by the seated person's buttocks. The front-side part 13 and the rear-side part 15 are made of a resin foam. The resin foam of the front-side part 13 is harder than that of the rear-side part 15.SELECTED DRAWING: Figure 1
【課題】クッション性(座り心地)が良好であり、かつ車両の衝突や急ブレーキをかけた時等による衝撃発生時のサブマリン現象を抑えることができる車両用シート基材と車両用シートを提供する。【解決手段】車両用シート基材11にクッション材21が積層された車両用シート10において、車両用シート基材11を、着座者の膝裏で加圧される前側部分13と、着座者の臀部で加圧される後側部分15とを備え、前側部分13及び後側部分15は樹脂発泡体であり、前側部分13の樹脂発泡体は、後側部分15の樹脂発泡体よりも硬くなっている。【選択図】図1
