The present application relates to an airbag cushion comprising the reinforcing fabric and a method for preparing the same. According to the present application, adequate levels of tenacity, elongation, dimensional stability, impact resistance and the like required for an airbag cushion and its reinforcing fabric are simultaneously met.

A process for coating a fabric web on upper and lower sides in one pass containing unwinding a fabric web, coating the upper side of the fabric web with a upper coating composition using a first coater, coating the lower side of the fabric web with a lower coating composition using a second coater, drying the coated fabric web in a horizontal dryer, and winding up the coated fabric web.

The upper and lower coatings are each in an add-on amount of between about 10 and 75 GSM. The second coater comprises an entry edge and a beveled exit edge, where the entry edge is located closer to the first coater than the beveled exit edge, the entry edge of the second coater is in contact with the lower side of the fabric web, and the beveled exit edge of the second coater is not in contact with the web.

Disclosed is a method for manufacturing a polyester fabric for an airbag that can not only prevent or minimize the separation of a sizing agent, which is provided to a yarn through a sizing process, during a weaving process, but can also maximize a peel strength between a textile substrate and a coating layer to be subsequently formed thereon and lower the stiffness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completed. The method of the present invention comprises: applying a polyester-based sizing agent to a polyester yarn; manufacturing a textile substrate with the sizing agent-applied polyester yarn; removing the sizing agent from the textile substrate under an alkaline condition of pH 8 to 10; and forming a coating layer on the sizing agent-removed textile substrate in order to enhance air-tightness.

The present invention provides a coating fabric for airbags where an elastomer is coated to at least one side of textile constituted from synthetic fiber filament, which is characterized in that the coating weight of the resin is as small as 10 to 20 g/m.sup.2 and an average resin thickness of the head top in the textile surface is 4.0 μm to 12.0 μm in both directions of warp and weft and that the average value of burning speed measured according to FMVSS 302 is not more than 60 mm/min in both directions of warp and weft and the maximum value thereof is not more than 1.2-fold to the average value in both directions of warp and weft.

The present disclosure relates to a dashboard protection arrangement, which is adapted to protect an accessory or a piece of equipment located at a central region of a dashboard of a vehicle from a deploying frontal protection airbag. The dashboard protection arrangement comprises a dashboard airbag adapted to deploy along a surface of the dashboard in order to at least partly cover the central region of the dashboard when deployed. The disclosure further relates to a vehicle comprising the dashboard protection arrangement and to a method of deploying a dashboard airbag of a dashboard protection arrangement.

A fabric for a seam region of an inflatable air-bag includes fibers formed from polyester and having an elongation at break of around 12% to 20%. The fabric also has an instantaneous thermal creep above 0.5% at 100° C.

The present invention relates to a coated fabric for an air bag obtained by applying an elastomer resin onto at least one side of a woven fabric made from synthetic fiber. The applied amount of the elastomer resin is 25 to 60 g/m.sup.2. The average resin thickness on warp and weft at head top of the woven fabric surface is 8 μm to 45 μm. The number of foams having diameter of 30 μm or larger is 100 or more/cm.sup.2 on the surface of a resin layer.

Disclosed is an inflation gas deflector for an automotive airbag assembly. The inflation gas deflector includes at least one layer of inorganic platelets that is supported by a thin metal support, or a multiple layer composite of at least one metal support layer, at least one inorganic platelet layer carried by the metal support layer, and at least one other functional and/or support layer. Also disclosed is an airbag cushion incorporating the inflation gas deflector and an automotive airbag assembly including the inflatable airbag cushion, the inflation gas deflector, and an inflator.

A sewn airbag includes a plurality of base fabrics sewn together, wherein in a sewn region where reinforcement is required, a reinforcing coating film made of an adhesive coating material that is adhesive to both a sewing yarn and fibers forming the base fabrics is formed on at least one of the upper and lower surfaces of the sewn region, the reinforcing coating film having the smallest possible width along a stitching region in the form of one or more strips forming the sewn region made with the sewing yarn.

A method of making a flame resistant airbag suitable for use in aviation applications is discussed. A flame resistant fabric for the use in the construction of aviation airbags is woven from a high tenacity continuous polyester fiber substrate. A polyurethane coating is applied to the woven fabric, which has been treated with a flame retardant, to impart high pressure permeability resistance to the flame resistant fabric. The resulting fabric complies with Federal Aviation Requirement 25.853 as well as exhibits sufficient high pressure permeability resistance which is measured as a pressure of not less than about 198 kPa after five seconds from an initial inflation and pressurization to about 200 kPa, such as may be encountered in and during an inflation of aviation airbag assemblies.
