To prevent the occupant-pressing force of an inner bag part from becoming excessively large due to the stretching of a seatback cover, even when the seatback cover is formed of an easily stretchable material.SOLUTION: In a vehicle seat 10, a side airbag 46 comprises an inner bag part 60 which is inflated between an outer side frame 24 and a seated occupant P. A lower part 36L of an outer Fr side cover 36 which forms part of a seatback cover 32 is interposed between the inflated inner bag part 60 and the seated occupant P. A back base fabric 70 which is formed so as to be less stretchable than the lower part 36L is joined to the back face of the lower part 36L. As a result, the stretching of the lower part 36L due to the inflation pressure of the inner bag part 60 is suppressed. Accordingly, even when the seatback cover 32 including the lower part 36L is formed of an easily stretchable material (for example, a knitted material), it becomes possible to prevent the occupant-pressing force of the inner bag part 60 from becoming excessively large due to the stretching of the lower part 36L.SELECTED DRAWING: Figure 3
【課題】シートバックの表皮が伸び易い材料で構成されている場合でも、内バッグ部の乗員押圧力がシートバックの表皮の伸びに起因して過大になることを防止する。【解決手段】車両用シート10では、サイドエアバッグ46が、外サイドフレーム24と着座乗員Pとの間で膨張する内バッグ部60を有している。膨張した内バッグ部60と着座乗員Pとの間には、シートバック表皮32の一部を構成する外側Frサイド表皮36のロア部36Lが介在する。このロア部36Lの裏面には、当該ロア部36Lよりも伸び難く構成された裏基布70が接合されている。これにより、内バッグ部60の膨張圧によるロア部36Lの伸びが抑制される。したがって、ロア部36Lを含むシートバック表皮32が伸び易い材料(例えばニット素材)で構成されている場合でも、内バッグ部60の乗員押圧力がロア部36Lの伸びに起因して過大になることを防止可能となる。【選択図】図3
