PROBLEM TO BE SOLVED: To provide a knee airbag which achieves simplification of a structure of the knee airbag while maintaining occupant restraint force, and to provide a knee airbag device.SOLUTION: A knee airbag device 1 includes: a knee airbag 2 which may be inflated and expanded between a dash board D and a lower leg part of an occupant M; and an inflator 3 which supplies a gas to the knee airbag 2. The knee airbag 2 includes: a left expansion part 21 which restrains a left leg; a right expansion part 22 which restrains a right leg; and a center expansion part 23 which is disposed between the left expansion part 21 and the right expansion part 22 and is inflated and expanded so as to protrude toward the occupant M. The center expansion part 23 includes: a center front surface part 23a which is located in front of the occupant M during inflation and expansion; and center extension parts 23b which are located at both sides of the center front surface part 23a and may be stored at a back surface of the center front part 23a while being folded in a bellows shape.SELECTED DRAWING: Figure 4
【課題】乗員拘束力を保持しつつ、ニーエアバッグの構造の簡略化を図ることができる、ニーエアバッグ及びニーエアバッグ装置を提供する。【解決手段】ニーエアバッグ装置1は、ダッシュボードDと乗員Mの下腿部との間で膨張展開可能なニーエアバッグ2と、ニーエアバッグ2にガスを供給するインフレータ3と、を備え、ニーエアバッグ2は、左足を拘束する左側膨張部21と、右足を拘束する右側膨張部22と、左側膨張部21と右側膨張部22との間に配置され乗員Mに向かって突出するように膨張展開される中央膨張部23と、を備え、中央膨張部23は、膨張展開時に乗員Mの前面に位置する中央正面部23aと、中央正面部23aの両側に位置し中央正面部23aの背面に蛇腹折りされた状態で収容可能な中央拡張部23bと、を備えている。【選択図】図4
