Title
(DE) GASSACKGEWEBE
(EN) AIRBAG FABRIC
(FR) TISSU DE COUSSIN GONFLABLE
Abstract
(DE) Ein Gassackgewebe für einen Gassack hat einen Befestigungsbereich (22) zur Befestigung des Gassacks. Dabei weist der Befestigungsbereich (22) eine Befestigungsöffnung (24), einen Belastungsabschnitt (26), der an die Befestigungsöffnung (24) in einer Belastungsrichtung (B) angrenzt, und einen Übergangsabschnitt (28) auf, der an die Befestigungsöffnung (24) entgegen der Belastungsrichtung (B) angrenzt. Ferner weisen der Belastungsabschnitt (26) und der Übergangsabschnitt (28) unterschiedliche Bindungen auf. Das Gewebe im Belastungsabschnitt (26) hat dabei eine geringere Verschiebefestigkeit als im Übergangsabschnitt (28), so dass sich ein Faserwulst aus den Gewebefasern des Belastungsabschnitts (26) ausbildet, der in der Belastungsrichtung (B) an die Befestigungsöffnung (24) angrenzt, wenn eine Lochleibungslast in der Belastungsrichtung (B) auf die Befestigungsöffnung (24) wirkt.
(EN) The invention relates to an airbag fabric for an airbag, having a securing region (22) for securing the airbag. The securing region (22) has a securing opening (24), a loading section (26) which adjoins the securing opening (24) in a loading direction (B), and a transition section (28) which adjoins the securing opening (24) opposite the loading direction (B). The loading section (26) and the transition section (28) additionally have different fixations. The fabric in the loading section (26) has a lower resistance to displacement than in the transition section (28) such that when a bearing stress acts on the securing opening (24) in the loading direction (B), a thread bead is formed from the fabric fibers of the loading section (26), said thread bead adjoining the securing opening (24) in the loading direction (B).
(FR) L’invention concerne un tissu de coussin gonflable pour un coussin gonflable qui présente une zone de fixation (22) pour la fixation du coussin gonflable. La zone de fixation (22) présente une ouverture de fixation (24), une partie de sollicitation (26) qui est adjacente à l'ouverture de fixation (24) dans un sens de sollicitation (B), et une partie de transition (28) qui est adjacente à l'ouverture de fixation (24) dans le sens opposé au sens de sollicitation (B). En outre, la partie de sollicitation (26) et la partie de transition (28) présentent des liaisons différentes. Le tissu qui se trouve dans la section de sollicitation (26) présente une résistance au déplacement plus faible que dans la partie de transition (28), de telle sorte qu'un bourrelet de fibres se forme à partir des fibres de tissu de la section de sollicitation (26) qui est adjacente à l'ouverture de fixation (24) dans le sens de sollicitation (B) lorsqu'une sollicitation par pression diamétrale s’exerce dans le sens de sollicitation (B) sur l'ouverture de fixation (24).
