ABSTRACT:
A head-protecting airbag adapted to be mounted on an upper periphery of a window of a vehicle for deployment downward to cover the window includes a primary inflatable portion that includes a protection portion for receiving an occupant's head and a secondary inflatable portion that admits inflation gas of the primary inflatable portion and is inflatable secondarily for preventing a pressure increase of the primary inflatable portion. The primary inflatable portion and the secondary inflatable portion are communicated with a tubular conduit. The protection portion includes an inlet-side inflatable portion located proximate an inlet port of the conduit and a lower inflatable portion located below the conduit. The lower inflatable portion is communicated with part of the inlet-side inflatable portion and has an opening dimension in a vertical direction that is greater than that of the conduit over an entire area below the conduit.
