PROBLEM TO BE SOLVED: To provide a passenger seat airbag device capable of easily adjusting a projecting direction of a fold block part of the most of a folded airbag region in an initial stage of airbag inflation.SOLUTION: An airbag 15 is stored in a storage part 12 as a fold completed body 39 produced from a prefolded airbag in a state of flat expansion folded to shrink width dimensions in forward and rearward directions and width dimensions in right and left directions. The prefolded airbag comprises a long part 29 and a short part 30 extending to the front side and the rear side of a gas inflow port, respectively, and configured by making length dimensions different. The fold completed body 39 comprises a fold block part 35 formed by folding the tip side of the long part 29 and arranged by being overlapped on the gas inflow port 18 with the inclusion of an occupant restraint face 15a, and a communication part 36 in continuity with the fold block part 35 from the gas inflow port 18 in the long part 29 and the short part 30 are arranged by being folded to overlap on the fold block part 35.SELECTED DRAWING: Figure 2
【課題】エアバッグの膨張初期段階において、エアバッグの大部分の領域を折り畳んでいる折塊部の突出方向を容易に調整可能な助手席用エアバッグ装置の提供。【解決手段】エアバッグ15は、平らに展開させた状態の予備折りエアバッグを、前後方向の幅寸法と左右方向の幅寸法とを縮めるように折り畳んだ折り完了体39として、収納部位12に収納される。予備折りエアバッグは、ガス流入口の前方側及び後方側に、それぞれ延びるとともに、長さ寸法を異ならせて構成される長尺状部位29と短尺状部位30とを備える。折り完了体39が、長尺状部位29の先端側を折り畳んで形成されて、乗員拘束面15aを介在させてガス流入口18上に重ねて配置される折塊部35を、備えるとともに、長尺状部位29におけるガス流入口18から折塊部35に連なる連通部36と、短尺状部位30と、を、折塊部35上に折り重ねて配置させている。【選択図】図2
