PROBLEM TO BE SOLVED: To provide a knee protection airbag which can suppress the block of vent holes caused by a vehicle body side member at deployment and expansion, and can suppress the discharge of expansion gases from the vent holes so that the gases progress toward an occupant side.SOLUTION: A knee protection airbag 26 has a vehicle body side panel part 27 which is arranged at a vehicle body side at the completion of expansion, and an occupant side panel part 28 which is arranged at an occupant side at the completion of the expansion. The knee protection airbag is formed into a bag shape by connecting peripheral edges 27c, 28b of the vehicle body side panel part and the occupant side panel part. The airbag comprises an attachment part 30 and a protection expansion part 40. The vehicle body side panel part and the occupant side panel part are constituted by arranging a connecting part 48 for connecting external peripheral edges and a non-connecting part 49 for maintaining non-connection states of the external peripheral edges at external peripheral edge sides. The non-connecting part is arranged in a region of the protection expansion part, and constitutes vent holes 50L, 50R which can discharge surplus expansion gases which flow into the vent holes.SELECTED DRAWING: Figure 3
【課題】展開膨張時に、車体側部材によるベントホールの閉塞を抑制でき、かつ、ベントホールからの乗員側に向かうような膨張用ガスの排気を抑制可能な膝保護用エアバッグを提供すること。【解決手段】膨張完了時に車体側に配置される車体側パネル部27と、膨張完了時に乗員側に配置される乗員側パネル部28と、を、有するとともに、車体側パネル部と乗員側パネル部との外周縁27c,28b相互を結合させることにより、袋状とされる膝保護用エアバッグ26。エアバッグが、取付部30と保護膨張部40とを備える。車体側パネル部と乗員側パネル部とが、外周縁側に、外周縁相互を結合させた結合部48と、外周縁相互の非結合状態を維持した非結合部49と、を配設させて構成される。非結合部が、保護膨張部の領域に配置されて、内部に流入した余剰の膨張用ガスを排気可能なベントホール50L,50Rを、構成している。【選択図】図3
