Abstract: A folding method of an airbag having a left airbag portion and a right airbag portion is disclosed. In one form, the method includes the steps of: a primary folding step for forming a primary folded body in which said airbag is flattened along a top-bottom direction and along a right-left direction by folding said airbag in a manner that decreases a thickness of said left airbag portion and said right airbag portion along a front-back direction and at least partially separates a left surface of said left airbag portion and a right surface of said right airbag portion along the right-left direction; and a secondary folding step for forming a final folded body by folding said primary folded body in a manner that decreases its width along the top-bottom direction and along the right-left direction.

Abstract: A passenger airbag apparatus for a vehicle includes a retainer, an airbag folded and retained in the retainer, a deployment-limiting sheet, and a shape-retaining sheet. The deployment-limiting sheet has one end coupled to the retainer or the rear portion of the airbag, and extends toward the front portion of the airbag while being superposed on the airbag. The deployment-limiting sheet has a first folded part and extends along the rear portion of the airbag during inflation of the airbag. The first shape-retaining sheet is coupled to the retainer or the deployment-limiting sheet for retaining a shape of the folded airbag and a shape of the deployment-limiting sheet. The first shape-retaining sheet has a shape-retainment release portion for releasing a shape of the folded airbag by inflation of the airbag.

Abstract: An airbag and an airbag apparatus in which a vent hole is in a closed state or a slightly open state until an occupant plunges into the airbag and the vent hole becomes to an open state or a widely open state when the occupant plunges into the airbag. The inside of the airbag 10 is partitioned by inner panels 22A, 22B into a first chamber 1 centrally located and a second chamber surrounding the first chamber 1. A vent hole 18 is formed in a rear panel 14 to allow the communication between the second chamber 2 and the outside of the airbag. A lid member 60 is provided to cover the vent hole 18 from the inside of the rear panel 14. A tether (tethering member) 70 connects the lid member 60 and the inner panels 22A, 22B. When the airbag 10 is inflated, the tether 70 is tensioned to prevent the lid member 60 from moving out of the airbag 10.

Abstract: A technique is provided effective in smoothing the airbag deploying motion of an airbag apparatus to be mounted to a motorcycle. In one form, an airbag apparatus mounted to a motorcycle is constructed to hold the loose portions of elongated webbings that join an airbag to the vehicle body in a predetermined bunched state as a folded portion while the airbag is housed, and to release the hold upon the deployment of the airbag.
