PROBLEM TO BE SOLVED: To make it possible to appropriately protect the head and chest of a passenger without significantly increasing the capacity of an air bag and the output of an inflator in a configuration in which a front passenger seat rotates.SOLUTION: An air bag device 10 for a front passenger seat comprises: a seat state detection sensor (detecting means) that detects a state of the front passenger seat 18, which is rotatable; an air bag module 14 provided in the vehicle front of the front passenger seat 18 and in which an air bag 26 intended to be inflated toward the front passenger seat 18 is folded; a drive mechanism 15 that carries out at least one of the movement and rotation, in a vehicle width direction, of the air bag module 14; and a passenger protection control (control means) that sets an inflation area of the air bag 26 to a reference position O, which is in front of the front passenger seat 18, in a case where it is determined on the basis of information of the seat state detection sensor that the front passenger seat 18 faces the vehicle front before a vehicle collision, and sets the inflation area of the air bag 26 further on the seat back 22 side than the reference position O in a case where the front passenger seat 18 faces laterally with respect to the vehicle front.SELECTED DRAWING: Figure 2
【課題】助手席が回転する構成において、エアバッグの大容量化やインフレータの高出力化を行うことなく、乗員の頭部や胸部を適切に保護できるようにする。【解決手段】助手席用エアバッグ装置10は、回転可能な助手席18の状態を検知するシート状態検知センサ(検知手段)と、助手席18の車両前方に設けられ、助手席18側へ展開するエアバッグ26が折畳み収納されたエアバッグモジュール14と、エアバッグモジュール14の車幅方向移動及び回動の少なくとも一方を行う駆動機構15と、車両衝突前において、シート状態検知センサからの情報に基づき、助手席18が車両前方に向いている場合、エアバッグ26の展開領域を助手席18の正面となる基準位置Oに設定し、助手席18が車両前方に対して横向きとなっている場合、エアバッグ26の展開領域を基準位置Oよりシートバック22側に調整する乗員保護制御(制御手段)と、を有する。【選択図】図2
