PROBLEM TO BE SOLVED: To provide a head protection airbag device in which an airbag has a simple configuration, and suitably receive a head of an occupant.SOLUTION: A head protection airbag device M comprises a bag body 21, and a connection cloth 51 which connects the bag body 21 and a body 1. The bag body 21 comprises: a first inflation part 30; a second inflation part 32 which is so provided as to be adjacent to the first inflation part 30 and in which a membrane length, which is freely inflatable in a cross direction, is so set as to be long on the vehicle inner side and short on the vehicle outer side; and a third inflation part 33 which is provided on a side of the second inflation part 32 opposite to the first inflation part 30 in the cross direction, and which receives inflation of the second inflation part 32 at inflow time of an inflation gas and is inflated toward the vehicle outer side. The connection cloth 51 is so provided as to be capable of supporting the vehicle outer side of the third inflation part 33. In inflation completion state of an airbag 20, the second inflation part 32 is pressed toward the vehicle inner side by the third inflation part 33 supported by the connection cloth 51.SELECTED DRAWING: Figure 5
【課題】エアバッグが簡便な構成で、乗員の頭部を適切に受け止めることができる頭部保護エアバッグ装置を提供すること。【解決手段】頭部保護エアバッグ装置Mは、バッグ本体21と、バッグ本体21とボディ1とを連結する連結布51と、を備える。バッグ本体21は、第1膨張部30と、第1膨張部30に隣接して設けられ、前後方向に自由膨張可能な膜長が車内側で長く、車外側で短かく設定された第2膨張部32と、第2膨張部32の第1膨張部30とは前後方向の反対側に設けられ、膨張用ガスの流入時に第2膨張部32の膨張を受けて車外側に向かって膨張しようとする第3膨張部33と、を備える。連結布51は、第3膨張部33の車外側を支持可能に配設されており、エアバッグ20の膨張完了状態で、第2膨張部32は、連結布51により支持された第3膨張部33により、車内側に向けて押圧されるように構成されている。【選択図】図5
