Publication number: 20080026657Abstract: Airbags are made from fabric blanks that contain two-layer and one-layer regions. Airbags with two-layer areas are commonly “nested” in such fabric blanks for high speed manufacture of many airbags simultaneously. Polymeric coating is applied to both exterior sides of the fabric blank. The fabric blank may be cured (or dried) in ovens to render the coating gas impermeable. Coated airbags in the “nest” are then cut from the fabric blanks into individual airbags. One-piece woven (OPW) airbags may be made in such a process. Certain specific areas of the fabric blanks may be made with specifically engineered weakened yarn weave patterns in defined areas to serve as gas escape points for undesirable gas collection within the two-layer fabric blanks during manufacturing process steps. Such vents are permeable to gas even though the vents are coated during the manufacturing process.Type: ApplicationFiled: July 5, 2007Publication date: January 31, 2008Inventor: John A. Sollars

Publication number: 20040224596Abstract: A breathable barrier material having a first nonwoven layer and a first microporous film bonded together to form a composite laminate. A second microporous film and a second nonwoven layer are bonded to the composite laminate and second film to form the barrier material such that the films are disposed between the nonwoven layers. The composite laminate is bonded to the second film and second nonwoven layer thereby creating bond points in the material and void spaces between the first and second films. The void spaces between films may enhance liquid and viral barrier properties in the barrier material by creating a boundary that minimizes passage of liquids and/or viral components through the barrier material.Type: ApplicationFiled: May 9, 2003Publication date: November 11, 2004Inventors: Michael P.

Patent number: 6806215Abstract: A composite structure for a protective garment, such as a protective garment for a firefighter, has a moisture absorber, a moisture barrier and an outer shell. The moisture barrier is disposed outwardly in relation to the moisture absorber, while the outer shell is disposed outwardly in relation to the moisture barrier. The moisture absorber has a fibrous matrix incorporating a superabsorbent polymer, as particles or as fibers, and is disposed between an inner cover pervious to moisture and an outer cover. The inner and outer covers may be quilted so as to segregate discrete regions of the fibrous matrix.Type: GrantFiled: May 20, 2002Date of Patent: October 19, 2004Assignee: Morning Pride Manufacturing, L.L.C.Inventors: William L.

Patent number: 6800573Abstract: A water-vapor-permeable, watertight, heat-reflecting flat composite is made by a process of combining a metal layer and a nonporous, water-vapor-permeable, watertight, hydrophilic flat substrate. The process includes at least the three steps of (1) selecting the substrate, (2) pre-cleaning the substrate, and (3) applying the substrate to the metal layer. Such a composite offers protection from heat loss, infrared-based detection, ultraviolet radiation, electro-smog, and static electricity.Type: GrantFiled: August 31, 2001Date of Patent: October 5, 2004Assignee: Sympatex Technologies GmbHInventors: Henricus J.

Publication number: 20040191507Abstract: A coated substrate comprises a strippable intermediate coating atop the substrate and a strip agent-permeable waterborne overcoat adhered to the intermediate coating, wherein the dried overcoat is less strippable and more wear-resistant than the dried intermediate coating. When the overcoat eventually becomes worn and must be renewed, a strip agent (e.g., chemical strip agent) can be applied to the overcoat. The strip agent penetrates the overcoat and attacks the intermediate coating, thereby enabling removal of the intermediate coating and overcoat without aggressive removal techniques such as sanding.Type: ApplicationFiled: April 9, 2004Publication date: September 30, 2004Inventors: Mark D. Levitt, Bryan Michael Anderson, Keith Edward Olson, Kim R. Smith

Patent number: 6792621Abstract: An article of clothing includes a waterproof inner fabric layer and an outer fabric layer. An outer opening is defined in the outer fabric layer and is selectively opened and closed by a standard zipper. A portion of the inner fabric layer extends between the edges of the outer opening and defines an inner opening. The inner opening is selectively opened and closed by a water-resistant zipper. Venting material extends between the edges of the inner opening and allows air to flow through the inner opening when both the inner and outer openings are opened.Type: GrantFiled: July 10, 2001Date of Patent: September 21, 2004Assignee: Harley-Davidson Motor Company Group, Inc.Inventor: David Braun

Patent number: 6794317Abstract: A protective cover system (100) for inhibiting corrosion of a metallic object. The protective cover system includes a cover (101, 200, 600) for defining a microenvironment and a corrosion inhibitor source for releasing one or more corrosion inhibitors into the microenvironment. In one embodiment, cover 200 comprises an outer liquid-impermeable layer (204), an inner liquid-permeable layer (202), and a superabsorbent layer (206) located between the outer and inner layers. In another embodiment, cover 600 includes a water-vapor-permeable layer (602) and a porous support layer (606) for supporting the water-vapor-permeable layer. In both of these embodiments, one or more corrosion inhibitors may be incorporated into the cover in one or more of the corresponding above-mentioned layers or in a layer separate from these layers, or may be provided in a separate container that fluidly communicates the corrosion inhibitor(s) to the microenvironment.Type: GrantFiled: August 27, 2002Date of Patent: September 21, 2004Assignee: Creare Inc.Inventors: Nabil A.
