Abstract
(EN)
Disclosed is an inflatable airbag with an inflation channel free of a heat mark, comprising two cavity films (3), boundaries of the two cavity films (3) being closed to form a bag body, and further comprising two valve films (4) arranged between the two cavity films (3); the upper ends of the two valve films (4) are closed to form an inflation channel (1), and the lower ends are inserted into the bag body to form an air inlet (6); the bag body and the valve films (4) are separated into a plurality of small cavities (2) by hot pressing; the two valve films (4) are coated with heat resisting layers (5) at closed portions of the cavity films (3), and the heat resisting layers (5) are arranged between the two valve films (4); and an inflation opening (8) is formed in the inflation channel (1). The inflatable airbag is simple in structure, and low in costs and rejection rate, and compared with the prior art, the processing procedure of a hot sealing area is reduced, the production efficiency is greatly increased, and a wide market prospect is achieved.
(FR)
L'invention concerne un coussin de sécurité gonflable comprenant un canal de gonflage dépourvu d'une marque de surchauffe, comprenant deux films de cavité (3), les limites des deux films de cavité (3) étant fermées pour former un corps de coussin, et comprenant en outre deux films de soupape (4) agencés entre les deux films de cavité (3) ; les extrémités supérieures des deux films de soupape (4) sont fermées pour former un canal de gonflage (1), et les extrémités inférieures sont insérées dans le corps de coussin pour former une entrée d'air (6) ; le corps de coussin et les films de soupape (4) sont séparés en une pluralité de petites cavités (2) par pressage à chaud ; les deux films de soupape (4) sont revêtus de couches thermorésistantes (5) au niveau de portions fermées des films de cavité (3), et les couches thermorésistantes (5) sont disposées entre les deux films de soupape (4) ; et une ouverture de gonflage (8) est formée dans le canal de gonflage (1). Le coussin de sécurité gonflable est de structure simple et de coûts et de taux de rejet faibles, et par comparaison avec l'état de la technique, la procédure de traitement d'une zone de scellement à chaud est réduite, l'efficacité de production est grandement accrue, et une large perspective de commercialisation est obtenue.
