To provide a knee airbag, a knee airbag device, and a knee airbag folding method, that can be applied even when an angular difference between a discharge direction and an expansion direction of the knee airbag is large.SOLUTION: A knee airbag 2 comprises a first inflation part 21, a second inflation part 22 and a third inflation part 23. The knee airbag 2 is constituted of one base cloth panel 2p having a vehicle body side surface 2a and an occupant side surface 2b. The base cloth panel 2p comprises: an adjustment part 24 in which a lengthwise direction width Yb2 of the occupant side surface 2b constituting the second inflation part 22 is formed to be longer than a lengthwise direction width Ya2 of the vehicle body side surface 2a constituting the second inflation part 22; a first sewing part 25 where both ends in the lengthwise direction are overlappingly folded and sewn together; and a second sewing part 26 in which both side parts are sewn together so as to intersect with the first sewing part 25 in a state where the adjustment part 24 is overlappingly folded and the lengthwise direction widths Ya2, Yb2 of the occupant side surface 2b and the vehicle body side surface 2a of the second inflation part 22 match with each other.SELECTED DRAWING: Figure 1

    【課題】ニーエアバッグの放出方向と展開方向との角度差が大きい場合にも適用することができる、ニーエアバッグ、ニーエアバッグ装置及びニーエアバッグの折畳方法を提供する。【解決手段】ニーエアバッグ2は、第一膨張部21と第二膨張部22と第三膨張部23とを備えている。ニーエアバッグ2は、車体側面2a及び乗員側面2bを備えた一枚の基布パネル2pにより構成されている。基布パネル2pは、第二膨張部22を構成する乗員側面2bの縦方向幅Yb2が第二膨張部22を構成する車体側面2aの縦方向幅Ya2よりも長く形成された調整部24と、縦方向の両端部を折り重ねて縫合した第一縫合部25と、調整部24を折り重ねて第二膨張部22の乗員側面2b及び車体側面2aの縦方向幅Ya2,Yb2を一致させた状態で両側部を第一縫合部25と交差するように縫合した第二縫合部26と、を備えている。【選択図】図1
