PROBLEM TO BE SOLVED: To suppress or prevent the head of a rear seat occupant from suddenly rotating around an axis in the vertical direction of a vehicle when the rebounded head of the rear seat occupant contacts a recess having different heights in the bag thickness direction formed between the front part of a rear seat side collision chamber and the rear part of a front chamber at the time of at least fine lap collision and oblique collision of the times of front face collision.SOLUTION: A curtain airbag device 10 for vehicle includes a protection cloth 94 which is formed of a separate body from a curtain airbag 14 and fixed to at least the upper edge of the curtain airbag 14. The protection cloth 94 is arranged from a surface 40A1 on the vehicle width direction inner side of a front part 40A of the rear seat side collision chamber 40 to a surface 44A1 on the vehicle width direction inner side of a rear part 44A of a front chamber 44 in the expansion completion state of the curtain airbag 14 and covers a recess 92 having different heights formed between the front part 40A of the rear seat side collision chamber 40 and the rear part 44A of the front chamber 44 from the vehicle width direction inner side.SELECTED DRAWING: Figure 1

    【課題】前面衝突時のうち少なくとも微小ラップ衝突時及びオブリーク衝突時に、リバウンドした後席乗員の頭部が後席用側突チャンバの前部と前方チャンバの後部との間に形成されたバッグ厚さ方向に高さ違いの凹部に当接した際に、後席乗員の頭部が車両上下方向の軸回りに急激に回転することを抑制又は防止する。【解決手段】車両用カーテンエアバッグ装置10は、カーテンエアバッグ14とは別体で構成され、かつカーテンエアバッグ14の少なくとも上縁側に固定された保護布94を備えている。保護布94は、カーテンエアバッグ14の展開完了状態で後席用側突チャンバ40の前部40Aの車両幅方向内側の表面40A1から前方チャンバ44の後部44Aの車両幅方向内側の表面44A1にかけて配置され、後席用側突チャンバ40の前部40Aと前方チャンバ44の後部44Aとの間に形成された高さ違いの凹部92を車両幅方向内側から覆っている。【選択図】図1
