Abstract
Apparatus, methods, and systems for retaining an airbag cushion to an airbag housing. Some embodiments may comprise an airbag housing comprising an outer surface, an airbag coupling ring configured to fit over the outer surface of the airbag housing, and an airbag cushion positioned in between the airbag housing and the airbag coupling ring such that the airbag cushion is pinched between the airbag coupling ring and the outer surface of the airbag housing so as to retain the airbag cushion to the airbag housing during deployment of the airbag cushion.
Claims21
An airbag assembly, comprising:
- an airbag housing comprising an outer surface and configured to receive an airbag cushion therein;
- an airbag coupling ring configured to fit over the outer surface of the airbag housing;
- and
- an airbag cushion positioned in between the airbag housing and the airbag coupling ring such that the airbag cushion is directly pinched between the airbag coupling ring and the outer surface of the airbag housing so as to retain the airbag cushion to the airbag housing during deployment of the airbag cushion.
An airbag assembly, comprising:
- an airbag housing comprising an inner peripheral surface and an outer peripheral surface;
- an airbag coupling ring configured to be slidably positioned adjacent to at least one of the inner peripheral surface and the outer peripheral surface of the airbag housing;
- and
- an airbag cushion contained within the airbag housing, wherein the airbag cushion is positioned in between at least one of the inner peripheral surface and the outer peripheral surface of the airbag housing and the airbag coupling ring such that the airbag cushion is directly pinched between the airbag coupling ring and the airbag housing so as to retain the airbag cushion to the airbag housing during deployment of the airbag cushion.
A method for assembly of an airbag assembly, the method comprising the steps of:
- obtaining an airbag housing comprising a bottom wall, the bottom wall defining an opening for receipt of an inflator;
- obtaining an airbag coupling ring;
- obtaining an airbag cushion comprising a throat and a closed end opposite from the throat;
- positioning a first end of the airbag housing into the throat of the airbag cushion;
- sliding the airbag coupling ring over the airbag cushion and the airbag housing such that a periphery of the airbag cushion is positioned between the airbag coupling ring and the airbag housing;
- and
- locking the airbag coupling ring to the airbag housing to secure the coupling ring to the airbag housing and retain the airbag cushion to the airbag housing during deployment of the airbag cushion.
