To provide a knee airbag device and a method for folding its knee airbag which can effectively protect the knee part of a seated occupant in a front seat upon frontal collision, in such a structure that the height position of the bulge-shaped part of an instrument panel is set on a vehicle upper side above the knee part of the seated occupant.SOLUTION: A vertical wall part 42 is adjacently provided on a vehicle lower side with respect to a lower end part on the vehicle front side of a bulge-shaped part 40 of an instrument panel 12. A knee airbag module 14 including a knee airbag 54 is mounted on the vehicle front side with respect to the vertical wall part 42. The knee airbag 54 of the knee airbag module 14 is supplied with gas to be inflated and deployed toward at least the front side of a knee part N of a seated occupant P in a front seat 30 and the lower side of the bulge-shaped part 40. The knee airbag 54 is set in such a manner that, in its inflated and deployed state, a counter-occupant side base cloth part 76F is arranged adjacently to the vertical wall part 42.SELECTED DRAWING: Figure 1

    【課題】インストルメントパネルの膨出形状部の高さ位置が前席の着座乗員の膝部よりも車両上方側に設定された構造において、前面衝突時に着座乗員の膝部を効果的に保護することができるニーエアバッグ装置及びそのニーエアバッグの折り畳み方法を得る。【解決手段】インパネ12の膨出形状部40の車両前方側の下端部に対して車両下方側には縦壁部42が隣接して設けられている。縦壁部42に対して車両前方側には、ニーエアバッグ54を備えるニーエアバッグモジュール14が搭載されている。このニーエアバッグモジュール14のニーエアバッグ54は、ガスの供給を受けて少なくともフロントシート30の着座乗員Pの膝部Nの前方側かつ膨出形状部40の下方側へ膨張展開される。ニーエアバッグ54は、その膨張展開状態で反乗員側基布部76Fが縦壁部42と隣接配置されるように設定されている。【選択図】図1
