A side airbag device incorporates an airbag which is fixed to and held by a vehicle so as to be folded in roll form, from a front portion to a rear portion of the vehicle, and which is expanded and developed like a curtain parallel with the inner surface of the side wall of the vehicle by a gas of an inflator when a collision is detected. An airbag support belt is attached to a portion, in close proximity to a top edge of the airbag and close to an attachment position of the inflator, of the airbag. The airbag support belt is wound around the circumferential surface of the inflator and a tip locking hole of the airbag support belt is fixed to a locking projection provided on the inflator, whereby the inflator is integrated with a part of the airbag which is folded in roll form.
A head protecting airbag device comprising an airbag (i) in which plural expansive support portions are arranged from a front portion to a rear portion of a vehicle so as to communicate with each other, (ii) which is fixed to and held by a portion of a vehicle body in a folded state so as to extend along a top edge of a side wall of the vehicle and (iii) which develops like a curtain parallel with an inner surface of the side wall of the vehicle while the expansive support portions are expanded by a gas that is introduced from an inflator which operates when a collision is detected or predicted,
