Abstract

L'invention concerne des tissus gonflables revêtus (26), notamment des airbags sur lesquels des faibles quantités additionnelles de revêtement ont été appliquées, et présentant des perméabilités à l'air extrêmement faibles. Les tissus de l'invention sont principalement destinés à être utilisés dans des coussins de sécurité d'automobile nécessitant des caractéristiques de perméabilité faibles (tels que des airbag latéraux). Habituellement, des couches lourdes et onéreuses de composés, tels que le néoprène, les silicones et similaires, sont utilisées pour que les faibles niveaux de perméabilité requis soient atteints. Ainsi, l'airbag revêtu de l'invention possède un revêtement d'au plus 2,5 onces par yard carré, et idéalement d'environ 0,8 once par yard carré, et présente un temps d'échappement (mesure du temps requis pour que la quantité de gaz introduite dans l'airbag à une pression de pointe pendant le gonflement s'échappe de l'airbag à 10 psi) d'au moins 7 secondes. L'invention concerne tous les revêtements, notamment les revêtements élastomères, non siliconés, et les airbags remplissant ces conditions.
