Definitions

  • the invention relates to an impact protection device, in particular for occupants of vehicles, in particular for vehicles, consisting of a cushion or cover cap, airbag (airbag), fastening part (e.g. holding plate), electronic or mechanical devices and gas generator; the airbag made of fabric (e.g. polyamide fabric) with or without a coating in turn consists of a fastening part on the gas inflow side, which is optionally equipped with a flame retardant, an upper part (per person) and tether straps; the ends of the tethers being connected to other components or connected to one another (joining points).

Abstract

L'invention concerne un dispositif de protection contre les chocs, notamment pour les occupants de véhicules, surtout de véhicules automobiles. Ce dispositif comprend un sac gonflable en tissu, avec ou sans revêtement et comprend un élément de retenue côté admission du gaz, une partie supérieure (côté impact de l'occupant) et des andes de retenue. Les extrémités des bandes de retenue sont reliées les unes aux autres ou bien à d'autres éléments (points d'assemblage). Afin de pouvoir relier les extrémités libres des bandes de retenue (1', 2') entre elles ou avec d'autres éléments constitutifs du sac gonflable, de manière à ce que les uns et les autres soient dans la bonne position et assurent un fonctionnement fiable dudit sac gonflable, il est par conséquent impératif de positionner et de fixer les extrémités des bandes de retenue, ainsi qu'éventuellement les autres éléments constitutifs, les uns par rapport aux autres, avant de les assembler. A cet effet, les bandes de retenue (1', 2') ou d'autres éléments constitutifs du sac gonflable comportent une perforation (6), une ou plusieurs partie(s) saillante(s) ou un ou plusieurs évidement(s) pratiqués dans la zone de chacun des points d'assemblage (3').
