CA 2389242

The invention relates to inflatable fabrics which comprise two separated and distinct fabric layers in discrete areas of such fabrics as well as connecting seam-producing materials to which such fabric layers are simultaneously attached. The resultant inflatable fabric composite thus includes inflatable areas separated, at least partially, by seamed barrier areas. This configuration will form "pillowed" structures within the target fabric upon inflation. Such connecting seam-producing materials are incorporated within the two-layer structure as peel seams in relation with the individual fabric layers. Upon inflation, the seams then act as shear seams which greatly increases the overall strength of the two-layer inflatable fabric. These shear seams thus provide a relatively effective manner of reducing air permeability within the entire fabric article. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary. In particular, the inventive fabric may be incorporated within an airbag cushion.

L'invention concerne des toiles gonflables comprenant deux couches de tissu différentes et séparées, placées dans des zones distinctes de ces toiles, ainsi que des matériaux de jonction utilisés pour la fabrication de coutures et auxquels sont attachées simultanément ces couches de tissu. La toile composite gonflable ainsi fabriquée inclut donc des zones gonflables séparées, au moins partiellement, par des barrières cousues. Cette structure permet la formation de <= bourrelets >= à l'intérieur de la toile, sous l'effet du gonflage. Les matériaux de jonction utilisés pour les coutures à l'intérieur de la structure en deux couches forment des coutures pelables sur chaque couche de tissu. Sous l'effet du gonflage, ces coutures deviennent alors des coutures arrachables, qui augmentent sensiblement la résistance globale de la toile gonflable à deux couches. Ces coutures arrachables constituent ainsi un moyen relativement efficace de réduire la perméabilité à l'air de l'article en toile dans son ensemble. Ladite toile peut être utilisée dans des applications nombreuses et variées lorsque le gonflage de la toile est nécessaire ou souhaité. La toile résultant de cette invention peut, en particulier, entrer dans la fabrication d'un coussin d'airbag.
