In order to provide a head protective airbag which is adapted to be not or scarcely inflated when it is dragged out of a pillar cover, whereby the airbag can be extremely smoothly dragged out of the pillar cover and to provide a head protective airbag device provided with the airbag, a head protective airbag (1) is provided with a triangular first cell (18) in a front portion of the airbag (1). The first cell (18) is in communication with a gas inlet (16) through first and second gas passages (21, 22). As an inflator (17) is actuated, gas flows first mainly into the first gas passage (21) through the gas inlet (16) so that the airbag (1) pushes and opens a roof trim (36B) above a B-pillar (37) and thus starts to deploy into a vehicle cabin. The first cell (18) is pulled by the first gas passage (22) (sic) and an area around the first gas passage (22) (sic) so as to tear a trim (36A) of an A-pillar (31) and come out of the trim (36A). After that, the first cell (18) is inflated. <IMAGE> |
