Abstract

L'invention concerne des tissus gonflables enduits (26), plus particulièrement des coussins gonflables auxquels a été appliqué un revêtement très fin, et qui présentent une très faible perméabilité à l'air. Ces tissus sont principalement utilisés pour des coussins gonflables de sécurité de véhicule automobile, qui doivent présenter une faible perméabilité (par exemple, des coussins gonflables formant rideaux latéraux). Cette faible perméabilité est obtenue grâce à un revêtement très fin et peu coûteux. Ce revêtement fait 2,5 onces par yard carré au maximum, de préférence environ 0,8 onces par yard carré, et présente un temps de fuite d'au moins 7 secondes. Tous les revêtements, en particulier les revêtements en élastomère, non siliconés, et les coussins gonflables enduits qui répondent à ces critères, entrent dans le cadre de cette invention.
