A knee protection airbag device includes an airbag. When the air bag is accommodated, an occupant side wall portion and a vehicle body side wall portion are overlapped and expanded flatly and roll-folding is performed such that an upper edge side of a knee receiving portion side approaches a lower edge side of the mounting portion side, end side portions on left and right sides of the roll-folded roll folding portion are formed as folded portions which fold over a central portion near a center in a left-right direction of the roll folding portion to form a folding completed body. A joining between a first overlapping portion and a tip side part of the airbag is released when an inflation gas flows into the airbag and when a fold of a first fold is canceled and the first overlapping portion deviates from a rear area of the central portion.

A side airbag apparatus includes an airbag that is configured to be deployed and inflated between a body side portion of a vehicle and an occupant seated in a seat in a passenger compartment by a pressure of gas supplied from an inflator. The airbag includes an outer bag and an inner bag, which is provided in the outer bag and accommodates the inflator. The inner bag includes an upper-side inflation portion, which projects forward when inflated to correspond to the shoulder of the occupant, a lower-side inflation portion, which projects forward when inflated to correspond to the lumbar region of the occupant, and a recessed portion, which is provided between the upper-side inflation portion and the lower-side inflation portion. The inner bag includes a connecting hole that connects the inside and the outside of the inner bag to each other.

An airbag assembly including an airbag body having a front side and an opposite rear side, a fold line provided on one of the front side and the rear side, the fold line configured to adjust a length of the one of the front side and the rear side such that a length of the rear side is greater than a length of the front side when the airbag body is in a deployed state, the fold line defining a lower boundary, and a sewn portion provided on an outer surface portion of the front side and an outer surface portion of the rear side. The sewn portion fixes an inner surface portion of the front side to an inner surface portion of the rear side at a location within a predetermined distance from the lower boundary.

A vehicle airbag assembly for a vehicle body includes an airbag having a storage position and an unfolded position, in the unfolded position the airbag features an inboard side facing an interior of the vehicle body, an outboard side facing an exterior of the vehicle body, a top portion fixed to the vehicle body, and a bottom portion located on a side of the airbag opposite the top portion. A fabric layer is adapted to overlay the outboard side of the airbag in the unfolded position, the fabric layer including a top portion and a bottom portion located on a side of the fabric layer opposite the top portion, the top portion of the fabric layer fixed to the top portion of the airbag.

A restraint system includes a side curtain airbag including an inboard panel, an outboard panel, and a perimeter at which the inboard panel and the outboard panel are connected to each other. The side curtain airbag includes a main portion formed of part of the inboard panel and part of the outboard panel, and a folded-over portion formed of part of the inboard panel and part of the outboard panel. The main portion and the folded-over portion each include a dead zone spaced from the perimeter at which the inboard panel and the outboard panel are connected to each other. The side curtain airbag is folded so that the inboard panel of the folded-over portion abuts the inboard panel of the main portion. The main portion and the folded-over portion are attached to each other via the respective dead zones.

A vehicle curtain airbag apparatus includes an inflator and an airbag. The airbag includes an airbag body, an inner tube, and a pocket portion. The inner tube includes a tube body and an insertion portion. The pocket portion is provided in a front end portion of the tube body in an insertion direction of the inner tube. A front end portion of the pocket portion in the insertion direction is joined to the tube body at a first joint portion, which extends in an intersecting direction. The intersecting direction intersects the insertion direction. At least one of the opposite end portions of the pocket portion in the intersecting direction is joined to the tube body at a second joint portion that extends in the insertion direction.

A vehicle occupant restraint device (10) comprises a pre-assembled head side airbag module (12) installed in a backrest (14) of a vehicle seat (16) and including an airbag (28) which deploys between two places adjacent transversely to the longitudinal vehicle direction and reduces lateral oscillation of a vehicle occupant toward an adjacent vehicle seat and/or an adjacent vehicle occupant. The head side airbag module (12) comprises a module housing (32) surrounding the airbag (28) at least partially in the installed condition which includes a guiding portion (34) extending on the side of the airbag (28) and exerting a force (F) upon the deploying airbag (28) so that during deployment the latter is pressed in the direction of the vehicle occupant to be restrained.

An active vent mechanism for an airbag apparatus that includes a first vent hole formed in an airbag and a patch capable of releasing and closing the first vent hole. A portion of the patch is coupled to the outer surface of the airbag. The airbag apparatus includes a coupling member having one end coupled to the patch and the other end entering the airbag and coupled to the airbag. A portion of the patch or a portion of the coupling member penetrates through an opening in the vicinity of the first vent hole. The airbag apparatus includes a substantially cylindrical regulating member into which the coupling member is inserted inside the airbag. The regulating member has a first end coupled to the inner surface of the airbag so as to surround the opening inside the airbag and a second end coupled to the coupling member in a sealed state.

A curable silicone adhesive having improved elongation-at-break and adhesive properties to various substrates, in particular synthetic textiles used in the manufacture of air bags, to be used, for example, as a joint sealer. These silicone compositions provide excellent adhesive properties such as peel strength and cohesive failure when used to seal joints/seams between two pieces of textile fabric. Airbag fabrics using such novel addition curable adhesive silicone compositions are also provided.
