Patent attributes
Airbag assemblies, such as overhead airbag assemblies, comprising overlapping pass-through chambers. In some embodiments, the assembly may comprise an airbag cushion configured to deploy from a vehicle roof structure and a head contact chamber configured to engage a head of an occupant of the vehicle upon deployment. An opening may be formed within the airbag cushion adjacent to the head contact chamber and may extend from a first surface of the airbag cushion configured to engage the occupant to a second surface of the airbag cushion opposite the first surface. The opening may be smaller along one or more dimensions than the head contact chamber upon deployment such that the head contact chamber cannot enter the opening without engaging one or more portions of the airbag cushion defining the opening.
