Abstract
A retainer secures an airbag inflator to a base plate of an apparatus for helping to protect an occupant of a vehicle. The retainer includes a base wall and a sidewall that extends from the base wall and is configured to encircle a discharge portion of the inflator from which the inflation fluid is discharged. The retainer also includes a filter liner secured to the retainer sidewall, wherein the sidewall and filter liner are configured so that inflation fluid discharged from the discharge portion is directed into the filter liner.
Claims20
A retainer for securing an airbag inflator to a base plate of an apparatus for helping to protect an occupant of a vehicle, the retainer comprising:
- a base wall and a sidewall that extends from the base wall and is configured to encircle a discharge portion of the inflator from which the inflation fluid is discharged;
- and
- a filter liner secured to the retainer sidewall and lining a surface of the retainer sidewall that encircles and faces the discharge portion of the inflator, wherein the sidewall and filter liner are configured so that inflation fluid discharged from the discharge portion is directed toward the filter liner, wherein the retainer is configured so that the filter liner is spaced from the discharge portion of the inflator so that it can receive and reduce the energies of particulates discharged from the inflator while inflation fluid can enter the airbag without passing through the filter liner.
A retainer for securing an airbag inflator to a base plate of an apparatus for helping to protect an occupant of a vehicle, the retainer comprising:
- a base wall and a sidewall that extends from the base wall and is configured to encircle a discharge portion of the inflator from which the inflation fluid is discharged;
- and
- a filter liner secured to the retainer sidewall, wherein the sidewall and filter liner are configured so that inflation fluid discharged from the discharge portion is directed into the filter liner,
- wherein the retainer comprises inward-turned rim portion of the retainer sidewall that defines a pocket in which the filter liner is received, the retainer being configured so that the retainer sidewall deflects outwardly in response to inflation fluid discharged from the inflator, the filter liner deflecting outwardly with the retainer sidewall, wherein the rim portion is configured to block particulates that pass through the outwardly deflected filter liner.
