Provided is an airbag which further reduces the degree of injury to a vehicle occupant while also exhibiting sufficient occupant protection performance using less output from the inflator, by both preventing airbag internal pressure from rising excessively when making contact with the occupant and increasing the speed of deployment in an occupant-protection area. This hollow-weave airbag has an opening in a main chamber that inflates for the purpose of occupant protection, a structure wherein a first yarn extending separatingly from a first fabric layer of the opening to a non-inflating portion is caught on a float yarn extending on the inside of a second fabric layer and subsequently caught on a float yarn extending on the inside of the first fabric layer, this structure being repeated at least once and forming a pair with another structure wherein a second yarn extending separatingly from the second fabric layer of the opening to the non-inflating portion is caught on the float yarn extending on the inside of the first fabric layer and subsequently caught on the float yarn extending on the inside of the second fabric layer, this structure being repeated at least once.

A vehicle seat for supporting an occupant in a sitting position includes a backrest, and an airbag unit. The airbag unit comprises an inflatable airbag provided in an initially rolled and/or folded airbag package, and an inflator actuable to direct inflating gas into the airbag to inflate the airbag into an inflated configuration. The airbag comprises a pair of inflatable chambers which are physically connected to one another via a connecting interface, and are fluidly isolated from one another. The airbag unit is mounted and configured such that, upon actuation of said inflator to inflate the airbag, the inflatable chambers inflate into respective deployed positions in which they: i) extend forwardly from respective opposing and laterally spaced-apart side regions of said backrest; and ii) extend upwardly, and laterally inwardly across an uppermost region of the seat towards said connecting interface, so as to thereby cooperate to define an inflated shroud around at least an uppermost region of the backrest so as to extend over the sitting position and provide lateral protection to a said occupant of the seat in the sitting position.

In one aspect, an apparatus for helping to protect an occupant of a vehicle includes a curtain airbag having a stored condition in which the curtain airbag is deflated, flattened, and rolled and/or folded. A wrap includes an integral woven portion of the curtain airbag formed from a fabric extension of an upper edge of the curtain airbag. The wrap has a first end portion where the wrap merges with the upper edge of the curtain airbag, and an opposite, free second end portion. The wrap is configured to wrap about a circumference of the rolled and/or folded curtain airbag. The second end portion is configured to connect to the first end portion of the wrap to secure the wrap on the curtain airbag and package the curtain airbag in the stored condition.

An OPW airbag has warp and weft threads woven together in a lower fabric layer, an upper fabric layer and a middle fabric layer arranged therebetween. The airbag has, arranged along a longitudinal axis, front, middle and rear portions. A generator mouth and an inflow region are in the front portion. Upper and lower main chambers are in the middle portion. A first plurality of lower stiffening chambers is in the rear portion between the middle and lower fabric layers. A second plurality of upper stiffening chambers is in the rear portion between the middle and upper fabric layers. At least one upper stiffening chamber, which is narrower compared to the lower stiffening chamber, is associated with each lower stiffening chamber. The lower stiffening chambers are each spaced apart by lower woven seams. Bridge chambers, which cover the lower woven seams, are arranged between the middle and upper fabric layers.

Provided is a textile for a hollow weave airbag, said textile being suitable for an airbag that has superior packability while satisfying internal pressure retention and abrasion resistance characteristics required from the airbag, and also has superior laceration resistance at the time of airbag deployment.

An OPW airbag having warp and weft threads woven together in at least three woven fabric layers: a lower fabric layer, an upper fabric layer, and a middle fabric layer therebetween. The weft threads of the middle fabric layer emerge from the middle fabric layer in a first partial region of the airbag and are tied partially to the upper fabric layer and partially to the lower fabric layer. The warp threads of the middle fabric layer emerge from the middle fabric layer in the first partial region of the airbag and float freely between the lower fabric layer and the upper fabric layer. The weft and warp threads of the middle fabric layer are incorporated into the lower fabric layer or into the upper fabric layer in a second partial region of the airbag or are tied to the lower or upper fabric layer at a few attachment points.

The present disclosure relates to a multi-layer fabric, and an airbag formed of the multi-layer fabric. The multi-layer fabric can provide an airbag capable of sufficiently protecting a driver or a passenger by minimizing damage caused by broken glass fragments when a vehicle is overturned.

An airbag includes a bag portion and a plain cloth portion. The bag portion is woven by double weave. The plain cloth portion is woven by plain weave at an edge of the bag portion. The bag portion and the plain cloth portion include warp threads and filling threads. The bag portion and the plain cloth portion are woven by a one piece woven method to satisfy: (1) each warp thread is not over four consecutive filling threads and each filling thread is not over four consecutive warp threads around a border between the bag portion and the plain cloth portion; and (2) every two adjacent warp threads are not over two adjacent filling threads and every two adjacent filling threads are not over two adjacent warp threads around the border.

An airbag package includes a one-piece woven airbag in a folded shape, a plurality of markers that are formed on the airbag, and a plurality of tape members that are bound around the airbag at locations of the markers for keeping the folded shape of the airbag. Each of the markers is composed of a weave structure that is different from that of surroundings in the airbag.
