To provide a ceiling-mounted airbag device capable of effectively restraining an occupant irrespective of a position, in a front-rear direction, of a vehicle seat; and to provide an occupant restraint apparatus including the same.SOLUTION: A ceiling-mounted airbag device 30 includes: an airbag 32 mounted on an upper side of a ceiling of a cabin and including a first chamber 34 which, when gas is supplied from an inflator 28 upon a head-on collision of a vehicle, thereby ruptures the ceiling and is expanded and deployed in front of an occupant P seated in a vehicle seat 12, and a second chamber 36 which, when the gas is supplied from the first chamber 34, is thereby expanded and deployed toward the occupant P; and a tension member 38 which couples the first chamber 34 to a support part 22 provided on the upper side of the ceiling, which ruptures the ceiling and is deployed with expansion and deployment of the first chamber 34, and which relatively pulls the first chamber 34 rearward and upward when the second chamber 36 restrains the occupant P about to move forward due to inertia force. An occupant restraint apparatus 10 includes the ceiling-mounted airbag device 30.SELECTED DRAWING: Figure 3

    【課題】車両用シートの前後位置に関係なく、乗員を効果的に拘束できる天井付けエアバッグ装置と、それを備えた乗員拘束装置を得る。【解決手段】車室の天井の上方側に搭載され、車両の前面衝突時にインフレータ28からガスが供給されることにより、天井を開裂して車両用シート12に着座している乗員Pの前方側に膨張展開する第1チャンバ34と、第1チャンバ34からガスが供給されることにより、乗員Pへ向けて膨張展開する第2チャンバ36と、を有するエアバッグ32と、第1チャンバ34と天井の上方側に設けられた支持部22とを連結するとともに、第1チャンバ34の膨張展開に伴って天井を開裂して展開し、慣性力によって前方側へ移動しようとする乗員Pを第2チャンバ36で拘束したときに、第1チャンバ34を後方側で、かつ上方側へ相対的に引っ張る引張部材38と、を備えた天井付けエアバッグ装置30と、それを備えた乗員拘束装置10とする。【選択図】図3
