Abstract
A head protective airbag which is adapted to not be inflated or to be scarcely inflated when dragged out of a pillar cover is provided. The airbag can be extremely smoothly pulled or dragged out of the pillar cover. The head protective airbag is provided with a triangular first cell in a front portion of the airbag. The first cell is in communication with a gas inlet through first and second gas passages. As an inflator is actuated, gas flows first mainly into the first gas passage through the gas inlet so that the airbag pushes and opens a roof trim above a B-pillar and thus starts to deploy into a vehicle cabin. The first cell is pulled by the first gas passage and an area around the first gas passage so as to tear a trim of an A-pillar and come out of the trim. After that, the first cell is inflated.

6. An airbag for the side of a vehicle comprising:
-
a plurality of inflatable cells positioned along a longitudinal direction of the vehicle, wherein each of the inflatable cells is configured so that gas is introduced into the cell adjacent only a top or a bottom of the airbag; a gas inlet having a first end adapted to be connected to an inflator and a second end fluidly connected to the plurality of inflatable cells, wherein the gas inlet is configured so that gas from the inflator enters the airbag only through the second end of the gas inlet; and a first gas passage extending in a vertical direction and located between at least two of the inflatable cells; wherein one end of the gas passage is positioned opposite the second end of the gas inlet so that the gas passage inflates downwardly prior to any substantial inflation of any of the plurality of cells. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
