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.

Method of making a flame resistant airbag suitable for use in aviation applications

A flame resistant fabric for the use in the construction of aviation airbags comprises a polyester fiber substrate which is treated with a first flame retardant. A polyurethane coating is applied to the polyester fiber substrate, which has been treated with the first flame retardant, to impart high pressure permeability resistance to the flame resistant fabric. The polyurethane coating comprises a second flame retardant to insure that the flame resistant fabric complies with Federal Aviation Requirement 25.853. The flame resistant fabric further comprises 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.

Flame resistant fabric for aviation airbags

An airbag is disclosed that comprises a first fabric layer, a second fabric layer, and an adhesive. The first and second fabric layers are coated with silicone elastomer coatings. The adhesive is a heat-cured silicone adhesive, and forms a seam-bond between the first and second layers such that a bag-like structure is created.

Airbag

An airbag comprises a pair of fabric layers and a thermoplastic covering on the fabric layers applied by extruding the covering onto a surface of each of the fabric layers. The covering is configured to seal the airbag when heated such that no stitched seam is used to seal the airbag. A primer may be applied between a fabric layer surface and covering to aid in adhesion of the covering to the fabric layer. The airbag can also include internal seams formed by the heat sealed, thermoplastic covering composition.

Thermoplastic coated, heat-sealed airbag

An airbag. The airbag includes a heat shield made of a thermal resistant material that prevents a pyrotechnic inflator's clinkers and hot gas from damaging the airbag or injuring the vehicle occupant. The thermal resistant material is a base fabric web with an elastomeric coating that includes a high aspect ratio additive such as vitreous fibers of alumina silicates. The resulting thermal resistant material exhibits exceptionally good thermal resistance times while, at the same time, uses relatively low coating weights.

Highly thermal resistant material for a vehicle safety device

A fabric having balanced stress-strain characteristics in the warp and weft directions. A method of processing the fabric includes overfeeding a woven fabric web along a first direction at one or more steps of a treatment process to facilitate crimping of the woven fabric web in the first direction. The overfeeding is indicative of a predetermined differential between a feed rate and a process rate at the one or more steps. The differential is adapted to cause the crimping in the first direction to substantially match a the level of crimping in a second direction.

Fabric having balanced elongation

An airbag fabric which has been coated with a polyamide coating, comprising a thermoplastic silicone vulcanizate. The coating may be adhered to the airbag fabric without the use of a primer and may be cured at room temperature. The coated airbag fabric may be reheated during fabrication and heat welded at the fabric boundary.

Silicone vulcanizate coated fabric

A laminated material including a decorative or functional cover layer laminated to a porous material layer. The cover layer may include a rigid, semi-rigid or flexible material and the porous spacer material layer may include a reticulated foam, nonwoven textile, or a spacer fabric. The cover layer is laminated onto the porous material layer, increasing the seam strength, durability and dimensional stability of the material.

Laminated spacer fabric

A fabric cartridge for an automotive beating and cooling system. The apparatus includes: a cartridge assembly, the cartridge assembly including a housing; and a single-ply, die cut fabric web disposed therein. In the preferred embodiment, the fabric web includes: a float-free fabric substrate; at least one surface including a laminated film; and a plurality of apertures for diverting airflow in the heating and cooling system; and a noise/friction reduction agent for reducing the interaction between the housing and the fabric web.
