To improve energy absorption performance of an airbag inflated and deployed from a seat rear side of an upper part of a vehicle seat to a seat front side.SOLUTION: An airbag device 30 comprises: an inflator for generating gas upon vehicle collision; and an airbag 32 supplied with the gas to be inflated and deployed from a seat rear side of an upper part of a vehicle seat 12 to a seat front side. The airbag 32 comprises: a front-rear chamber 34 comprising a pair of left and right front-rear extension parts 34A that passes through left and right sides of a head H of an occupant D seated in the vehicle seat 12 and is inflated and deployed to the seat front side, and a connection part 34B connecting front end parts of the pair of front-rear extension parts 34A in a seat left-right direction; and an airbag body 40 that is inflated and deployed to the occupant D side at a seat rear side of the connection part 34B later than the front-rear chamber 34, and that, when the occupant D is restrained, is compressed in a seat front-rear direction while stretching the front-rear chamber 34 in the seat front-rear direction.SELECTED DRAWING: Figure 1

    【課題】車両用シートの上部のシート後方側からシート前方側へ膨張展開するエアバッグのエネルギ吸収性能を向上させる。【解決手段】エアバッグ装置10は、車両の衝突時にガスを発生するインフレータと、前記ガスが供給され、車両用シート12の上部のシート後方側からシート前方側へ膨張展開するエアバッグ32と、を備えている。エアバッグ32は、車両用シート12に着座した乗員Dの頭部Hの左右両側を通ってシート前方側へ膨張展開する左右一対の前後延在部34A、及び一対の前後延在部34Aの前端部をシート左右方向に繋ぐ連結部34Bを有する前後チャンバ34と、連結部34Bのシート後方側で前後チャンバ34に遅れて乗員D側へ膨張展開し、乗員Dの拘束時に前後チャンバ34をシート前後方向に伸張させつつシート前後方向に圧縮されるエアバッグ本体40と、を有する。【選択図】図1
