Abstract
Airbag cushion assemblies comprising an airbag inflation tunnel positioned within an airbag cushion. Some embodiments may comprise an airbag cushion comprising an inflator opening and an airbag inflation tunnel coupled to the airbag cushion. The inflation tunnel may be configured to direct inflation gas from an inflator positioned within the inflator opening down the airbag inflation tunnel upon deployment of the inflator. A plurality of directional vent openings may be positioned within the airbag inflation tunnel that may be configured to direct the inflation gas laterally relative to the inflator. The inflation tunnel may further be configured such that the inflation gas contacts a terminal end of the inflation tunnel prior to exiting the plurality of directional vent openings.
