Abstract: To provide a protective cushion for a vehicle occupant's head which can introduce gas into chambers simultaneously or with desired time lags among the chambers. A cushion 1 comprises an occupant-side sheet 2 and a body-side sheet 3 which are superposed on each other and sewn together so as to form vacant chambers 11 through 14 between the sheets 2 and 3. A cylindrical member 20 is disposed between upper portions of the sheets 2, 3. Gas supplied through a rear end 21 of the cylindrical member 20 is introduced into the chambers 11 through 14 through openings 22, 23 and a front end 24 of the cylindrical member 20.

Abstract: In a method of forming an airbag, first and second main panels for constituting an airbag, and first and second inner panels in a form of a strip are prepared. The first and second inner panels are sewed together along longitudinal directions thereof without interposing a material therebetween, and an adhesive is provided at edge portions of the first and second main panels. The first and second inner panels sewed together are disposed between the edge portions of the first and second main panels so that the first and second main panels are directly joined together along the peripheries of the first and second main panels by the adhesive. The first and second inner panels sewed together are directly joined to the first and second main panels by the adhesive, respectively.

Abstract: An airbag device which is easily aligned in an instrument panel and which includes a lid that does not lift from the instrument panel. The airbag device includes a retainer, an airbag folded and accommodated in the retainer, a lid for covering the opening of the retainer, and an inflator for deploying the airbag. The device includes a belt wrapped around the outside of the retainer. The ends of the belt are connected to the lid. The edge of the opening of the instrument panel includes two steps. The first step supports the edge of the lid and the second step supports a spacer. The belt has an elastically deformable portion that stretches to ensure that the belt remains in elastic contact with the bottom of the retainer.

Abstract: An airbag is formed of first and second main panels joined together at a joining portion to form a chamber, a first inner panel bonded to the first main panel, and a second inner panel bonded to the second main panel. The first and second inner panels are interposed between the first and second main panels, and are joined to each other at a position away from the joining portion of the first and second main panels. The airbag can securely prevent gas leakage at the joining portion of the first and second panels.

Abstract: A lightweight air bag apparatus which facilitates the positioning between an instrument panel and a lid, and to provide an air bag apparatus in which the lid is not attached to a retainer in substance. The air bag apparatus includes a retainer, an air bag which is folded and stored in the retainer, a lid which covers the open surface of the retainer, and an inflator (gas generator) for expanding the air bag. The external surfaces of the retainer are surrounded by belts, and both ends of the belts are fixed to the leg portions and with rivets, bolts, or other fittings. The peripheral portion around an opening formed in the instrument panel is clamped between the edge portion of the lid and the extending portions. The belts are not connected to the retainer.

Abstract: To improve the strength in the connection between an inflator and an airbag, an area around a gas inlet 12 of an airbag 10 is fitted onto an inflator 30 and is bound tightly by two bands 14. The areas of the airbag 10 near the bands 14 are provided with stitches 16 extending in the circumferential direction of the inflator 30. The stitches 16 rise from the outer surface of the airbag 10. The areas around the gas inlet of the airbag 10 and the inflator 30 are held by saddle bands 24 of a holder 20. The stitches 16 are caught by the bands 14 when the airbag 10 is inflated and the airbag 10 is about to be slipped off, thereby securely preventing the detachment of the airbag 10.
