Method of attaching a mounting bracket to an airbag inflator
First Claim
1. A method of attaching a mounting bracket to an inflator having a sidewall and a peripheral inflator flange radially extending from the sidewall, the method comprising:
- providing a unitary mounting bracket having an annular support, a flange seat adjacent the annular support for receiving the peripheral inflator flange, and a sleeve sized and shaped to receive the inflator flange, the sleeve extending from the flange seat and having a distal portion;
sliding the sleeve of the mounting bracket over the sidewall of the inflator until the flange seat butts against the inflator flange; and
deforming the distal portion of the sleeve radially inwardly to form a clamping band underlying at least a portion of the inflator flange, thereby clamping the inflator flange between the clamping band and the flange seat to secure the mounting bracket to the inflator.

Abstract
A method of attaching a mounting bracket to an inflator having a cylindrical sidewall and a peripheral inflator flange radially extending from the sidewall that includes: providing a unitary mounting bracket having a annular support, a flange seat adjacent the annular support for receiving the peripheral inflator flange and a cylindrical sleeve extending from the flange seat and having a distal portion; sliding the cylindrical sleeve of the mounting bracket onto the inflator until the inflator flange butts against the flange seat; and applying a suitable amount of axial force to the distal portion of the sleeve so that the distal portion deforms radially inwardly into a clamping band underlying at least a portion of the inflator flange. The inflator flange is clamped between the clamping band and the flange seat to secure the mounting bracket to the inflator. Preferably, a crimping die is used to crimp the distal portion of the sleeve into a clamping band while the inflator is supported in an inflator nest.

10. A method of attaching a mounting bracket to an inflator having a cylindrical sidewall and a peripheral inflator flange radially extending from the sidewall, the method comprising:
-
providing a unitary mounting bracket having a continuous annular support, a continuous flange seat adjacent the annular support for receiving the peripheral inflator flange, and a cylindrical sleeve extending from the flange seat and having a distal portion; sliding the cylindrical sleeve of the mounting bracket over the sidewall of the inflator until the flange seat butts against the inflator flange; and applying a suitable amount of force to the distal portion of the sleeve to deform the distal portion radially inwardly into a continuous clamping band underlying at least a portion of the inflator flange to clamp the inflator flange between the clamping band and the flange seat, thereby securing the mounting bracket to the inflator and preventing the inflator from rotating with respect to the mounting bracket.

11. A method of attaching a mounting bracket to an inflator having a cylindrical sidewall and a peripheral inflator flange radially extending from the sidewall, the method comprising:
-
providing a unitary mounting bracket having an annular support, a flange seat adjacent the annular support for receiving the peripheral inflator flange, and a cylindrical sleeve extending from the flange seat and having a distal portion; providing a crimping die having a generally concave depression sized to receive the distal portion of the cylindrical sleeve; sliding the cylindrical sleeve of the mounting bracket over the sidewall of the inflator until the flange seat butts against the inflator flange; placing the concave depression of the crimping die over the distal portion of the cylindrical sleeve; and applying a suitable amount of axial force to the crimping die so that the crimping die deforms the distal portion of the sleeve radially inwardly into a clamping band underlying at least a portion of the inflator flange to clamp the inflator flange between the clamping band and the flange seat and thereby secure the mounting bracket to the inflator. - View Dependent Claims (12, 13, 14, 15, 16)
