Definitions

  • the invention relates to a gas bag for a personal protection system of a vehicle according to the preamble of patent claim 1 and a method for its production.
  • the additional layer is indeed connected substantially gas-tight with the one main layer, but a main layer has openings to the environment, so that it is depressurized in the inflated state of the airbag.
  • the one main layer is formed in this embodiment as a pressure-free protective layer.
  • the other main position and the additional position serve in this variant from the outset the maintenance of an internal gas pressure over a desired time.
  • the additional layer covers at least a portion of the main layer in which the openings are located to the environment.
  • the tether 5 or more tethers can be realized in an oblique arrangement, d. H. provide a diagonal bracing between the two main layers 1, 2.
  • Below the chamber 65 is located in the lower region 1 10 of the gas bag 100 in the middle of an elongated darts 63, which is also referred to below as Ovalab overseer and which is defined by a circumferential double seam 45, which connects the two main layers 1, 2 together.
  • the oval dart 63 defines a guide channel 64 which extends between the peripheral seam 44 and the oval dart 63. This guide channel 64 serves to receive the already mentioned filling tube 7. This is formed for example of a rigid to tough metal or plastic.
  • the opening 82 of the fabric layer 23 is elongated and formed by cutting a piece of fabric strip 84 along cutting lines 821 from the edge.
  • the cutting edges 821, along which the fabric strip 84 has been separated from the fabric layer 23, define the delimitations of the opening 82.
  • the fabric strip 84 is not completely separated from the fabric layer 24 but is still connected to the fabric layer 23 at one end 822.
  • the opening formed by the overlap region 83 thus comprises a first edge 81 a, which is formed by the opening 81 and a second edge 82 a, which is formed by the edge of the bent fabric strip 84.
  • the defined by the edges 81 a, 82 a opening 83 is in each case smaller than the openings 81, 82. It is dimensioned such that the gas lance 7 can be tightly fitted against the edges 81 a, 82 a in the guide channel 64 into it.

Abstract

L'invention concerne un sac gonflable pour un système de protection de personne d'un véhicule. Le sac gonflable présente une première couche principale (1) et une deuxième couche principale (2) qui forment une enveloppe de sac gonflable pouvant être gonflée et une couche supplémentaire (3) qui est disposée à l'intérieur de l'enveloppe sur le côté intérieur d'une des couches principales (1). Selon l'invention, les deux couches principales (1, 2) et la couche supplémentaire (3) sont reliées ensemble par au moins une couture commune (41, 411, 412) qui s'étend le long d'un bord périphérique (65) du sac gonflable étendu à plat. La couture commune (41, 411, 412) est retournée et se trouve à l'intérieur de l'enveloppe de sac gonflable, et la couche supplémentaire (3) est reliée de manière pratiquement étanche aux gaz à la couche principale (1) et est conçue de manière à être également disposée sur le côté intérieur de la couche principale (1), quand l'enveloppe de sac gonflable est complètement gonflée. L'invention concerne également un procédé de fabrication d'un tel sac gonflable.
