CURTAIN AIRBAG DEVICE

PROBLEM TO BE SOLVED: To provide a curtain airbag device capable of reducing the size of an airbag body and extending a rear row inflation part of the airbag body below a belt line at the time of inflation.SOLUTION: A facilitation part (26, 26', 26"), which is formed of a non-inflation part of an airbag body (21, 21', 21") and facilitates folding of the airbag body (21, 21', 21") at the time of inflation of the airbag body (21, 21', 21"), is provided in at least one air chamber (35 g) disposed at a lower end part of the airbag body (21, 21', 21") in a curtain airbag device (10). The air chamber (35g) comprising the folding facilitation part (26, 26', 26") has a flow passage through which gas circulates so as to go around the facilitation part (26, 26', 26") from one direction side.SELECTED DRAWING: Figure 1 【課題】エアバッグ本体のサイズを小さくすることが可能で、且つ、膨張展開時にエアバッグ本体の後列用膨張部をベルトラインよりも下方に延出させることが可能なカーテンエアバッグ装置を提供する。【解決手段】本発明のカーテンエアバッグ装置(10)におけるエアバッグ本体(21,21´,21″)の下端部に配される少なくとも１つの気室(35g)に、前記エアバッグ本体(21,21´,21″)の非膨張部からなり、前記エアバッグ本体(21,21´,21″)の膨張展開時に前記エアバッグ本体(21,21´,21″)の折り曲げを促す折り促進部(26,26´,26″)が設けられ、その折り促進部(26,26´,26″)を備える気室(35g)は、ガスが折り促進部(26,26´,26″)を一方向側から回り込むように流通する流路を有する。【選択図】図１
