PROBLEM TO BE SOLVED: To make a route of its airbag hard to escape in the direction separating from an occupant, in an inflation-expansion process of the airbag stored in a side part on the inside in the vehicle width direction of a backrest.SOLUTION: In an airbag installed in a backrest of a seat mounted on a vehicle and stored in a state of folding up in a side part on the inside in the vehicle width direction of the backrest, the airbag comprises a lower side folding-up part being a part of folding up a lower side area part of becoming the vehicle lower side in an inflation-expansion state of the airbag, an upper side folding-up part being a part of folding up an upper side area part of becoming the vehicle upper side in the inflation-expansion state of the airbag and an intermediate folding-up part being a part of folding up an intermediate area part of becoming the middle between the lower side area part and the upper side area part in the inflation-expansion state of the airbag, and the intermediate folding-up part is a roll folding part for wrapping the upper side folding-up part by roll folding of winding on the side of becoming the opposite side of the side part in the inflation-expansion state of the airbag.SELECTED DRAWING: Figure 10
【課題】背もたれの車幅方向内側の側部内に収納されたエアバッグの膨張展開過程で、そのエアバッグの進路が乗員から離れる方向に逸れ難くすること。【解決手段】車両に搭載された座席の背もたれに設置されており、前記背もたれの車幅方向内側の側部に折り畳まれた状態で収納されたエアバッグであって、前記エアバッグの膨張展開状態で車両下側となる下側領域部が折り畳まれた部分である下側折り畳み部と、前記エアバッグの膨張展開状態で車両上側となる上側領域部が折り畳まれた部分である上側折り畳み部と、前記エアバッグの膨張展開状態で前記下側領域部と前記上側領域部との中間となる中間領域部が折り畳まれた部分である中間折り畳み部とを備え、前記中間折り畳み部は、前記エアバッグの膨張展開状態で前記側部とは反対側となる側に巻くロール折りで、前記上側折り畳み部を包むロール折り部である、エアバッグ。【選択図】図10
