To provide a vehicle airbag device and an occupant protection apparatus comprising the same, capable of achieving both easy deployment of an airbag and occupant restraint stability.SOLUTION: A vehicle airbag device 30 comprises: an airbag 32 which is inflated and deployed from a seat rear side of a vehicle seat 12 toward a seat front side thereof; and a pair of left and right rear tethers 54 connecting the airbag 32 to a seatback 16 of the vehicle seat 12 or to a vehicle body. The airbag 32 comprises: a pair of left and right front-rear extension parts 34A which are inflated and deployed toward the seat front side through both left and right sides of a head H of an occupant D; 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 which is inflated and deployed at a seat rear side of the connection part 34B toward the occupant D side later than a front-rear chamber 34. During occupant restraint, the pair of rear tethers 54 pulls the pair of respective left and right front-rear extension parts 34A relatively toward the seat rear side and obliquely downward to bring the connection part 34B close to a thigh part F of the occupant D.SELECTED DRAWING: Figure 11

    【課題】エアバッグの展開し易さと乗員の拘束安定性とを両立することができる車両用エアバッグ装置及びこれを備えた乗員保護装置を得る。【解決手段】車両用エアバッグ装置30は、車両用シート12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、エアバッグ32と車両用シート12のシートバック16又は車体とを連結する左右一対の後方テザー54と、を有し、エアバッグ32は、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と、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側へ膨張展開するエアバッグ本体40と、を備え、一対の後方テザー54は、乗員拘束時に左右一対の前後延在部34Aをそれぞれシート後方斜め下方に相対的に引き込み連結部34Bを乗員Dの大腿部Fへ近づけるむように構成される。【選択図】図11
