Abstract
An airbag assembly includes an airbag cushion, an inflator to provide inflation gas to inflate the airbag cushion, a diffuser provided between the inflator and the airbag cushion and a deflector provided between the inflator and the diffuser. The diffuser forces the inflation gas to change flow direction at least one time before the inflation gas exits into the airbag cushion. The deflector deflects particulates emitted from the inflator into a predetermined portion of the diffuser to inhibit particulates from entering into the airbag cushion. The predetermined portion of the diffuser may be an upper corner of the diffuser.
Claims20
An airbag assembly, comprising:
- an airbag cushion;
- an inflator configured to provide inflation gas to inflate the airbag cushion;
- a diffuser provided between the inflator and the airbag cushion, the diffuser being configured to force the inflation gas to change flow direction at least one time before the inflation gas exits the diffuser and enters into the airbag cushion;
- and
- a deflector provided between the inflator and the diffuser, the deflector being configured to deflect particulates emitted from the inflator into a predetermined portion of the diffuser to inhibit particulates from entering into the airbag cushion.
An airbag assembly, comprising:
- an airbag cushion;
- an inflator configured to provide inflation gas to inflate the airbag cushion;
- a diffuser provided between the inflator and the airbag cushion, the diffuser including a plurality of panels configured to force the inflation gas to change flow direction at least two times before the inflation gas exits the diffuser and enters into the airbag cushion;
- and
- a deflector provided between the inflator and the diffuser, the deflector being configured to deflect particulates emitted from the inflator into a predetermined portion of the diffuser to inhibit particulates from entering into the airbag cushion,
- wherein the each of the plurality of panels include openings for inflation gas to pass through, the openings on one panel are not aligned with the openings on an adjacent panel.
A method of making an airbag assembly, comprising:
- providing a panel comprising a body portion and a rectangular flap, the rectangular flap including a first marker line, a second marker and a third marker line;
- folding the rectangular flap along the first, second and third marker lines to create a deflection surface;
- folding the panel along a central longitudinal midline of the panel;
- and
- attaching the folded panel to an inflator, a diffuser or a combination thereof.
