Abstract
Airbag cushion assemblies for aspirating ambient air and related assemblies, methods, and components. Some embodiments can comprise an aspirating airbag cushion assembly comprising an airbag cushion, which may be configured to deploy from a housing or the like. The assembly can further comprise a securement element to secure an inflator of the airbag cushion assembly during inflation of the airbag cushion. The assembly can further comprise an one or more inflation conduits configured to deliver inflation gas into the airbag cushion through a plurality of aspiration ports.
Claims20
An aspirating airbag inflation assembly, comprising:
- an airbag cushion;
- an aspiration housing fluidly coupled to the airbag cushion, wherein the aspiration housing comprises an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion;
- and
- an inflation module comprising:
- an inflator;
- a support element configured to physically receive at least a portion of the inflator, wherein the support element comprises a plurality of threads;
- and
- a securement ring configured to physically engage the support element with the inflator at least partially disposed within the support element, wherein the securement ring comprises a plurality of mating threads to engage the plurality of threads of the support element and retain the inflator within the support element during the inflation of the airbag cushion with a portion of the inflator secured between the securement ring and the support element.
An aspiration housing to be fluidly coupled to an airbag cushion of an airbag assembly, comprising:
- an aspiration inlet configured to facilitate introduction of ambient air into the airbag cushion during inflation of the airbag cushion;
- a support element at an endplate of the aspirating housing, the support element to receive an inflator to be disposed in fluid communication with the aspiration inlet, wherein the support element comprises a plurality of threads;
- and
- a securement ring configured to physically couple with the support element, wherein the securement ring comprises a plurality of mating threads to engage with the plurality of threads of the support element to secure the inflator at the support element in fluid communication with the aspiration inlet and to retain the inflator during the inflation of the airbag cushion with a portion of the inflator secured between the securement ring and the support element.
