PROBLEM TO BE SOLVED: To provide a lower limb protective air bag which can exactly protect a shin part of a crewman who moves to oblique front side.SOLUTION: A lower limb protective air bag 40 which is folded and stored in the front of a crewman D seated on a seat and covers a front side of a lower limb LB of the crewman D by introduction of a gas for expansion into the interior thereof. The lower limb protective air bag 40 includes: a body expansion part 42 which covers the front side of the lower limb LB of the crewman D at the time of completion of expansion; and a shin protection part 49 which is located on at least one side of the body expansion part 42 in a longitudinal direction, and is so located as to project from the body expansion part 42 at the time of completion of expansion thereby covering a ;lateral side of a shin part L of the crewman D. The shin protection part 49 is so configured that expansion thereof is completed at an internal pressure higher that of the body expansion part 42.SELECTED DRAWING: Figure 15
【課題】斜め前方に向かって移動する乗員の脛部を、的確に保護可能な下肢保護用エアバッグを提供すること。【解決手段】座席に着座した乗員Dの前方に折り畳まれて収納されるとともに、内部に膨張用ガスを流入させて、乗員Dの下肢LBの前方を覆うように膨張する下肢保護用エアバッグ40。下肢保護用エアバッグ40は、膨張完了時に乗員Dの下肢LBの前方を覆う本体膨張部42と、本体膨張部42の左右方向の少なくとも一方の端側に配置されるとともに膨張完了時に本体膨張部42から後方に突出して乗員Dの脛部Lの側方を覆うように配置される脛保護部49と、を備える。脛保護部49が、本体膨張部42よりも高い内圧として膨張を完了させるように、構成されている。【選択図】図15
