An inflatable band occupant restraint system includes an inflatable band that is configured to lower the stresses encountered by the band fabric during inflation and secondary impact. This reduction is accomplished by including a pleat pattern that better approximates the ideal cylindrical curvature of the band when inflated, attaching the band to a seat belt using a smaller radius attachment portion, and stitching the pleated portion of the band to the belt while maintaining the center of the band stitching-free.
La présente invention concerne un système de retenue de passagers à bande gonflable comprenant une bande gonflable configurée pour réduire les contraintes auxquelles est soumis le matériau de la bande au cours du gonflage et au moment de l'impact secondaire. La présente invention permet d'atteindre ce but en incluant un motif de plis qui permet de mieux reproduire la courbure cylindrique idéale de la bande gonflée, en attachant la bande à une ceinture de sécurité sur une zone de fixation à rayon plus petit, et en cousant la partie plissée de la bande à la ceinture tout en veillant à ce que le centre de la bande reste dépourvu de coutures.
