Abstract
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.
