A head-protecting airbag device includes a case which houses an airbag in a folded-up configuration and a mounting bracket which is used to mount an inflator on a vehicle body structure. The case is mounted on a region of the airbag extending from one end of the inflator. The mounting bracket includes an insert region which fits in an assembling opening of the case. The assembling opening includes a receiving region which receives the insert region along an axial direction of the inflator and a limiting plane that is located in a periphery of the receiving region and holds the insert region from rotating in both directions in a circumferential direction of the inflator. The fitting of the insert region and assembling opening suppresses the airbag stored in the case in the folded-up configuration from rotating in a circumferential direction.

Head-protecting airbag device

A case includes an opening at least at the lower region for receiving an airbag, and an engaging region engageable with a mounting bracket. The mounting bracket includes a mounting section which protrudes out of the case and a joint plate which is formed generally into a plate extending generally along an up and down direction and is disposed at a root region of the mounting section for engagement with the case. The engaging region of the case includes an insert slot which allows the joint plate to slide therein generally in an up and down direction, a retaining pawl which protrudes generally in an inboard-outboard direction and is inserted into a retaining hole of the joint plate and retains the joint plate, and an inboard side pressing surface and an outboard side pressing surface which press the joint plate retained by the retaining pawl on the inboard and outboard sides.

A head-protecting airbag device includes: an airbag including: an airbag body; and a connecting tab connected with a mounting bracket, wherein the mounting bracket includes: a mounting piece mounted on the body with a fixing means; and a connecting piece formed to project to both sides from a lower end of the mounting piece, and connected with the airbag; in the connecting tab, an insertion hole, into which the mounting piece is inserted, is disposed in a folded portion; the connecting tab includes a front side portion and a back side portion which extend from the folded portion to the airbag body and cover a font side and a back side of the connecting piece; and a loop coupling portion is disposed in a position where the mounting piece having the connecting piece stored in the connecting tab is prevented from coming off the insertion hole.

A head-protecting airbag device includes an airbag and a plurality of casings, each of which stores a folding completion body of the airbag, wherein: each of the casings has an opening for protruding the airbag; the casings are connected to each other by bendable coupling pieces; the folding completion body is configured to be carried in a state of being stored in one casing of the casings by bending of the coupling pieces; the coupling piece has a curved portion that is disposed in a curved manner by reversing between a base portion and a tip portion; and the curved portion is formed such that a protruding direction from a reference line connecting the base portion and the tip portion of the coupling piece is set in a direction intersecting with a surface along an overlapping direction of a longitudinal direction of the one casing with openings.
