Abstract
A head-protecting airbag device includes an airbag that is inflatable in such a manner as to separate an inboard side wall and an outboard side wall while unfolding downward from a housing. The airbag includes a front inflatable shielding region that covers an inboard side of a window and includes a sub inflatable region that is inflatable later than the main inflatable region. The sub inflatable region includes a supportive inflatable region that is supported by a vehicle body member which is disposed below a beltline. The airbag is stored in the housing such that a front lower corner of the sub inflatable region is folded inward on a crease extending obliquely rearward and downward from the front edge to the lower edge of the airbag before the airbag is subjected to a vertical size reducing folding that brings the lower edge as unfolded flatly close to the upper edge.
