Title (EN) ASPIRATING AIRBAG ASSEMBLIES

Abstract:
(EN) Airbag cushion assemblies for aspirating ambient air to enhance inflation. Some embodiments may comprise an inflation module comprising an inflator and a plurality of high-velocity nozzles fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into an airbag cushion. A housing coupled to the airbag cushion, may comprise an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion. The plurality of high-velocity nozzles may be configured to, upon actuation of the inflator, draw ambient air into the airbag cushion along with the inflation gas from the inflator. In some embodiments, a valve assembly may be provided that is configured to open upon actuation of the inflator and to close following inflation of the airbag cushion to prevent air and inflation gas from exiting through the aspiration inlet.
(FR) La présente invention concerne des ensembles de coussin de sécurité gonflable pour aspirer l’air ambiant afin d’améliorer le gonflage. Certains modes de réalisation peuvent comprendre un module de gonflage comprenant un dispositif de gonflage et une pluralité de buses à haute vitesse raccordées de façon fluidique au dispositif de gonflage et configurées pour distribuer un gaz de gonflage provenant du dispositif de gonflage dans un coussin de sécurité gonflable. Un boîtier couplé au coussin de sécurité gonflable peut comprendre une entrée d’aspiration configurée pour permettre la réception d’air ambiant dans le coussin de sécurité gonflable pendant le gonflage du coussin de sécurité gonflable. La pluralité de buses à haute vitesse peut être configurée pour, lors de l’actionnement du dispositif de gonflage, aspirer l’air ambiant dans le coussin de sécurité gonflable conjointement avec le gaz de gonflage provenant du dispositif de gonflage. Dans certains modes de réalisation, un ensemble de valve peut être disposé qui est configuré pour s’ouvrir lors de l’actionnement du dispositif de gonflage et se fermer après le gonflage du coussin de sécurité gonflable pour empêcher l’air et le gaz de gonflage de sortir par l’entrée d’aspiration.
