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.
