20090079104 | Wire mesh filter with improved hoop strength - A compressed wire mesh filter for an airbag assembly has one or more wires wrapped around the outer perimeter of the filter prior to final compression of the mesh to increase the hoop strength of the filter. | 03-26-2009 |
20090184504 | EXPANDED METAL FILTERS - Expanded metal sheets are used to produce tubular filters. The expanded metal sheet has a multiplicity of rows of openings arranged to reduce nesting when the sheet is rolled on itself. In particular, the pitch between the rows of openings, the sizes of the openings, or both the pitch between the rows of openings and the sizes of the openings are varied to reduce nesting when the expanded metal sheet is rolled on itself. The filters can include external circumferential grooves, rounded corners produced by a point loading process, textured surfaces between openings, and/or torturous internal paths produced by non-perforated areas of an expanded metal sheet. The expanded metal sheet can be composed of carbon steel coated with a material having a higher heat conductivity, e.g., tin. Among other things, the filters can be used in automobile airbag inflators to capture slag and absorb heat produced by the inflator's explosive charge. | 07-23-2009 |
20100146922 | Wound Wire Filter Elements - A cylindrical wound wire filter with an inner bore, suitable for use with an airbag inflator, has at least two different outer diameters and/or at least two different inner diameters. Wires in adjacent layers can be bonded together by adhesive or brazing, or have a sheet-like material therebetween, such as a ceramic filter paper. | 06-17-2010 |
20110061436 | EXPANDED METAL FILTERS - Expanded metal sheets are used to produce tubular filters.
