To provide a head protective airbag device capable of suppressing strong interference with an occupant head of an airbag during inflation in the vicinity of a front side of an assist grip.SOLUTION: There is provided an airbag 20 which covers an indoor side of a window including an area at a lower side of an assist grip 9F mounting fitting parts 11F, 11B at an upper edge WU side of a window W1. The airbag comprises a gas inflow part 22 expanded by causing inflation gas to flow in, and a non-inflow part 40 not causing inflation gas to flow in. The gas inflow part has a shield inflation part 27 for covering an area of the window at the lower side of the assist grip. The non-inflow part has a peripheral edge part 41 surrounding a peripheral edge of the gas inflow part, and a thickness regulation closing part 47 for regulating a thickness in inflation of the shield inflation part. The shield inflation part is so formed that a closing part 47 is arranged at an upper part side of the shield inflation part below the front fitting part 11F, and the closing part 47 is not provided below the rear fitting part 11B without extending the closing part 47 backward.SELECTED DRAWING: Figure 4
【課題】アシストグリップの前側付近における膨張時のエアバッグの乗員頭部との強干渉を抑制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】取付部11F,11Bを窓W1の上縁WU側に取り付けたアシストグリップ9Fの下方の領域を含めて、窓の車内側を覆うエアバッグ20を備える。エアバッグは、膨張用ガスを流入させて膨らむガス流入部22と、膨張用ガスを流入させない非流入部40と、を備える。ガス流入部は、アシストグリップの下方の窓の領域を覆う遮蔽膨張部27を備える。非流入部は、ガス流入部の周縁を囲う周縁部41と、遮蔽膨張部の膨張時の厚さを規制する厚さ規制閉じ部47と、を備える。遮蔽膨張部は、前側取付部11Fの下方における遮蔽膨張部の上部側に、閉じ部47を配設させ、閉じ部47を後方へ延設させずに、後側取付部11Bの下方に、閉じ部47を設けない構成としている。【選択図】図4
