Definitions

  • the invention relates to a fabric which is made from a synthetic fibre, preferably polyamide, and which constitutes a cloth possessing high tensile and tear strengths.
  • the cloth is intended to be used as the material of impact-protective, inflatable air bags utilised in motor vehicles.
  • a gas generator is used of a kind comprising a propellant which upon ignition rapidly develops a hot, air-bag inflating gas.
  • the substance generally used is sodium azide (NaN 3 ) , which forms nitrogen gas (N 2 ) .
  • the invention provides a fabric by means of which all problems referred to above are solved.
  • the characteristic feature of the invention is that the fabric face forming the inner face of the air bag has a coating applied thereon.
  • the coating consists of one or several layers of polymer with admixture thereto of a pigment having heat-reflecting properties.
  • a suitable coating for this purpose has been found to be a silicone elastomer with admixture thereto of an aluminium paste or aluminium pigments .
  • Measurements were carried out on a fabric sample mounted on a spacer ring, with the aluminium-coated surface facing downwards, towards a heated measurement plate and spaced 15 mm from the plate.
  • the environmental climate condi- tions were as follows: temperature 20°, relative humidity 65%, air velocity 0.5 m/s.
  • the fabric may be thin, yet strong at the same time, and therefore requires only a small space inside the module.
  • a fabric with said coating applied thereon is able to resist also high-temperature gases. Consequently, a propellant may be used that develops a higher-temperature gas than does sodium azide but that is non-toxic, and this without involving risks for fusion damages to the fabric .
  • the thermal reflection increases the pressure inside the bag.
  • the power of the gas generator may be reduced and a smaller amount of propellant need be used.
  • the air bag is exposed to less stress while at the same time cost savings are made.

Abstract

L'invention concerne un textile tissé en fibres synthétiques, de préférence, en fibres de polyamide. Ce tissu constitue une étoffe de grande extensibilité et de grande résistance à la déchirure, utilisée pour la fabrication des airbags des véhicules automobiles, ces airbags étant destinés à protéger contre les impacts. La face du tissu, destinée à être tournée vers l'intérieur de l'airbag, est dotée d'un revêtement qui est constitué d'au moins une couche polymère à laquelle ont été ajoutés des pigments aux caractéristiques réfléchissantes.
