To provide an airbag device capable of appropriately restraining an occupant even when a vehicle has had offset collision or oblique collision, and the occupant has moved to a seat oblique front side; and to provide an occupant protection device comprising the same.SOLUTION: An airbag device 30 comprises an airbag 32 supplied with gas generated in an inflator upon vehicle collision to be inflated and deployed from a rear side of a vehicle seat 12 to a front side through an upper side. The airbag 32 in an inflated and deployed state comprises: a pair of front-rear chambers 34 extending in a front-rear direction through left and right sides of a head H of an occupant D; and an airbag body 40 that is in communication with the pair of front-rear chambers 34, is disposed at a front side of the occupant D between the pair of front-rear chambers 34, and is compression-deformed while being supported by the pair of front-rear chambers 34 when the occupant D is restrained. The airbag device 30 inhibits at least the head H of the occupant D from entering gaps between the front-rear chambers 34 and the airbag body 40 during a latter half of restraint of the occupant D.SELECTED DRAWING: Figure 1
【課題】車両がオフセット衝突又は斜め衝突して乗員がシート斜め前方側へ移動したときでも、その乗員を適切に拘束できるエアバッグ装置と、それを備えた乗員保護装置を得る。【解決手段】車両の衝突時にインフレータで発生したガスが供給され、車両用シート12の後方側から上方側を通って前方側へ膨張展開するエアバッグ32を備えたエアバッグ装置30であって、膨張展開状態のエアバッグ32は、乗員Dの頭部Hの左右両側を通って前後方向に延在する一対の前後チャンバ34と、一対の前後チャンバ34と連通され、一対の前後チャンバ34の間で乗員Dの前方側に配置され、乗員Dの拘束時に一対の前後チャンバ34に支持された状態で圧縮変形されるエアバッグ本体40とを有し、乗員Dの拘束後半時に、少なくとも乗員Dの頭部Hが前後チャンバ34とエアバッグ本体40との隙間に入り込むのを抑制するように構成する。【選択図】図1
