To provide an air bag device which is a simple structure and can smoothly release a connection state with connection means when an actuator is activated.SOLUTION: An air bag device includes an actuator 35 to which string-shaped connection means 32 extending from an air bag 25 is connected, and which controls expansion form of the air bag through keeping or releasing the connection state with the connection means. The actuator includes: a gas generator 37 which can burst combustion gas BG; and a holder part 45 which can hold the connection means. The holder part includes: a holding wall part 48 which can hold the connection means wound on an outer peripheral surface side; a ceiling wall part 51 which covers the tip side of the holding wall part; and a contact possible area 49 which is arranged in the area of the holding wall part so that combustion gas can contact with the connection means. The actuator makes combustion gas contact with the connection means in the contact possible area to cut off the connection means, thereby releasing the holding state of the connection means with the holder part.SELECTED DRAWING: Figure 9
【課題】簡便な構成として、かつ、アクチュエータの作動時に、連結手段との連結状態を円滑に解除可能なエアバッグ装置を提供すること。【解決手段】エアバッグ25から延びる紐状の連結手段32を連結させ、連結手段との連結状態を維持若しくは解除させることにより、エアバッグの膨張形態を制御する構成のアクチュエータ35を、備える。アクチュエータが、燃焼ガスBGを噴出可能なガス発生器37と、連結手段を保持可能なホルダ部45と、を備える。ホルダ部が、外周面側で巻き掛けた連結手段を保持可能な保持壁部48と、保持壁部の先端側を塞ぐ天井壁部51と、を備えて、保持壁部の領域に、燃焼ガスを連結手段に接触可能な接触可能領域49を配設させる。アクチュエータが、接触可能領域において、燃焼ガスを連結手段と接触させることにより、連結手段を切断させて、連結手段のホルダ部との保持状態を解除可能とされる。【選択図】図9
