Abstract: An airbag includes a bag body that includes a first panel and a second panel which are opposed to each other, a partitioning tether that is disposed in such a manner as to partition an interior of the bag body, a communication hole that is formed in the tether for providing gas communication in the interior of the bag body, and first and second joints that respectively join first and second edges of the tether to the first and second panels of the bag body. The communication hole has a generally rectangular contour which has two corners in a vicinity of each of the first and second edges of the tether. In both of the first and second edges of the tether, the corners of the communication hole are disposed closer to the first or second edge of the partitioning tether than a corresponding one of the joints.

Abstract: An airbag device includes an airbag, an inflator and a retainer. The retainer includes a generally tubular holding section for holding the inflator therein and mounting means which protrudes out of the holding section in a direction generally perpendicular to an axis of the inflator to be mounted on a vehicle body member in order to mount the airbag and the inflator on the vehicle body member. The holding section includes an elastically deformable support region which has been elastically deformed and brought into abutment against an outer circumference of the inflator when the inflator was inserted into the holding section, and supports the inflator in the elastically deformed state at an inner side of the holding section, and a supporting projection which has higher rigidity than the elastically deformable support region and abuts against the outer circumference of the inflator at the inner side of the holding section.

Abstract: An airbag includes a body, an insert opening and a flap member which covers the insert opening from inside of the airbag. A retainer is inside the airbag, and an inflator is inserted into a holding section of the retainer via the insert opening such that the root end protrudes from the insert opening. The flap member entirely covers the insert opening of the airbag body as unfolded and is joined to the airbag body, with a continuous seam, by the circumferential edge except the leading edge disposed towards the leading end of the inflator. The flap member thus covers the holding section. The retainer includes an open region which exposes an outer periphery of the inflator towards the flap member, and the leading edge of the flap member is positioned to be pressed against the outer periphery of the inflator via the open region at airbag deployment.

Abstract: An airbag includes an insert opening. An inflator is inserted into the airbag via the insert opening and set in a holding section of a retainer which is disposed inside the airbag. The retainer includes, at its end region disposed towards the insert opening of the airbag, two retaining pawls that are in engagement with a periphery of the insert opening. The insert opening is composed of a plurality of slits formed on a base material of the airbag such that one or more area among the slits serve as a bent sealing region that is bent inward and covers an outer periphery of the inflator. The slits include a pair of retaining slits that intersect each other. Each of the retaining pawls protrudes from a terminal of each of the retaining slits. A peripheral area of the retaining slits constitutes the bent sealing region.

Abstract: A retainer and an inflator are disposed inside the airbag. The retainer includes a mounting base section, a holding section which extends from the mounting base section and receives and holds an inflator therein, and a second mounting means which protrudes from the mounting base perpendicularly. The inflator includes a cylindrical body provided with a gas release section and, a first mounting means protruding from a region of the body disposed outside the airbag. The retainer further includes a storing dent section which receives the first mounting means of the inflator so as to conform an orientation of the first means to that of the second mounting means and, a pressing section disposed proximate the storing dent section. The pressing section is brought into close contact with a circumferential area of the body of the inflator when the first mounting means of the inflator is secured to a vehicle body.

Abstract: An airbag device includes an airbag deployable out of a housing when fed with inflation gas, a limitation member capable of constraining a part of the airbag from unfolding and deploying, a wrapping member which wraps the airbag for keeping the folded-up configuration, and a flap member capable of covering an abnormally-seated vehicle occupant from the airbag. The limitation member has flexibility and includes a temporal holding section which holds a folded region of the airbag in a releasable fashion, a mounting section by which the limitation member is mounted on the housing and a connecting section connecting the mounting section and the temporal holding section. The temporal holding section includes a holding recess and frees the folded region via an opening of the holding recess when a periphery of the opening is deformed at airbag deployment. The flap member is disposed between the limitation member and the wrapping member.

Abstract: An airbag apparatus includes an airbag that deploys and inflates while being unfolded from an accommodating portion, when inflating gas flows into the airbag; and a regulating member that is able to regulate the deployment and inflation of an airbag. The regulating member is flexible, and includes a temporary holding portion that releasably and temporarily holds a folded portion that is a part of the airbag; an attachment portion that is attached to the accommodating portion; and a connecting piece portion that connects the attachment portion and the temporary holding portion. The temporary holding portion includes a base portion that is continuous with the connecting piece portion, and a cover portion that forms a holding concave portion for temporarily holding the folded portion, and is connected to the base portion. An opening for releasing the folded portion is provided at an inner circumference of a non-connected release edge.

Abstract: The side impact airbag includes an airbag that is folded up from a state where an occupant-side wall and a vehicle-side wall having generally identical contours are lapped and flattened, through a vertical contracting step. The airbag includes at least either at the top or bottom a tucked portion that is formed in the vertical contracting step by tucking i.e. invaginating part of each of the occupant-side wall and the vehicle-sidewall inside the airbag. The tucked portion includes a main portion that is stored inside the airbag and a projecting region that extends vertically from the main portion in an exposed manner. The projecting region is folded back toward the vehicle-side wall so as to be located outside the main portion.

Abstract: According to the air bag apparatus, for example, a side air bag apparatus 20, in a mode in which a portion on a side of a connector portion 33 of an inflator 30 is exposed from a cylindrical portion 51 of a retainer 50, the inflator 30 is contained in the retainer 50. Further, an exposed portion of the inflator 30, that is, a portion thereof exposed from the cylindrical portion 51 of the retainer 50 is fastened together with an extended portion 52 substantially in a shape of a half cylinder extended from the cylindrical portion 51 of the retainer 50 by a clamp mechanism 60 in a state of being covered by an extraneous portion of a base cloth extended from an opening portion 41 of the air bag 40.

Abstract: In a film winding method, continuous polymer film of cellulose acetate being supplied is wound into a form of a film roll. During the winding step, looseness of outer turns of the film roll is prevented by pressing a rotatable lay-on roll against the film roll. The lay-on roll includes a surface material, formed in a cylindrical shape, for contacting the film roll. The surface material includes rubber, has volume resistivity of 102-1012 &OHgr;cm, and hardness of 30-70.
