Abstract
A head-protecting airbag apparatus includes an inflated airbag with a rear inflatable portion covering the vicinity of a rear window of a vehicle, and a gas supply passage that inflates the rear portion. The rear inflatable portion includes a main body portion and an inlet inflatable portion, with a belt-shaped closing portion that partitions the two. The upper communication port and the lower communication port of the belt-shaped closing portion allow the inflation gas to flow from the inlet inflatable portion to the inflatable main body. In both communication ports, the opening area of the lower communication port is larger than the opening area of the upper communication port so that the airbag inflates via the lower communication port upon normal inflation of the airbag, and then inflates via the upper communication port upon abnormal inflation when the lower communication port is obstructed.
