Abstract

An inflator bracket for a side curtain vehicle airbag assembly of a type for mounting along a roof rail of a motor vehicle interior and mounting an inflator for generating inflation gas for a side curtain airbag. The inflator bracket in the form of a formed sheet metal component providing a carrier section adapted to engage and support the inflator and extending to form a base section and forming at least one mounting tab having a hole therethrough for enabling a threaded fastener to fasten the bracket to the roof rail. A shelf formed by the bracket positioned between the mounting tab and the carrier section and extending generally perpendicular to the base section provides clearance for the fastening of the threaded fastener without interference with the curtain airbag. The bracket is provided in the form of an integrated structure incorporating the carrier section, the base section, the mounting tab, and the shelf.

Claims

1. An inflator bracket for a side curtain vehicle airbag assembly for mounting along a roof rail of a motor vehicle interior using a threaded fastener and for mounting an inflator for generating inflation gas for a side curtain airbag, the inflator bracket comprising;

the inflator bracket having a formed sheet metal component providing a carrier section adapted to engage and support the inflator and extending to form a base section and at least one mounting tab having a hole therethrough for enabling the threaded fastener to fasten the inflator bracket to the roof rail, and

a shelf oriented between the mounting tab and the carrier section extending generally perpendicular to the base section for providing clearance for the fastening of the threaded fastener through the mounting tab hole without interference with the curtain airbag, the bracket provided in the form of an integrated structure incorporating the carrier section, the base section, the mounting tab, and the shelf,

wherein the shelf is formed by a polymer material over-molded onto the tab of the inflator bracket.

2. The inflator bracket in accordance with claim 1, wherein the inflator bracket forms a first and a second of the mounting tabs with the first and second mounting tabs separated by a cutout section therebetween.

4. The inflator bracket in accordance with claim 1, wherein the shelf forms a perimeter edge which is rolled over to prevent damage to the side curtain during a deployment of the side curtain airbag.

5. The inflator bracket in accordance with claim 2, wherein the shelf is a first shelf element, further comprising a shelf element the first shelf element being associated with the first of the mounting tabs and the second shelf element being associated with the second of the mounting tabs.

6. The inflator bracket in accordance with claim 2, wherein the shelf is a single shelf element which extends between the first and second mounting tabs.

7. The inflator bracket in accordance with claim 1, wherein the shelf is defined by a shelf bracket element having a folded configuration with a first portion thereof overlying the mounting tab and affixed thereto and further defining a wall section forming the shelf.

8. The inflator bracket in accordance with claim 7, wherein the shelf bracket element is affixed to the mounting tab of the inflator bracket by welding, brazing, adhesives, or by mechanical deformation.

3. (canceled)

9. (canceled)

10. The inflator bracket in accordance with claim 9, wherein the polymer material forms a perimeter edge which embraces at least a portion of a perimeter edge of the mounting tab.

11. An inflator bracket for a side curtain vehicle airbag assembly for mounting along a roof rail of a motor vehicle interior using a threaded fastener and for mounting an inflator for generating inflation gas for a side curtain airbag, the inflator bracket comprising;

the inflator bracket made from a single sheet metal blank forming a carrier section adapted to engage and support the inflator and extending to form a base section and at least one mounting tab having a hole therethrough for enabling the threaded fastener to fasten the inflator bracket to the roof rail, and a shelf oriented between the mounting tab and the carrier section extending generally perpendicular to the base section for providing clearance for the fastening of the threaded fastener through the mounting tab hole without interference with the curtain airbag, the single sheet metal blank integrally forming the carrier section, the base section, the mounting tab, and the shelf,

wherein the mounting tab is formed by the sheet metal blank being folded over itself to define a fold section and with a first and a second metal thickness of the sheet metal forming the mounting tab, and extending to form the shelf.

12. The inflator bracket in accordance with claim 11, wherein the inflator bracket forms a first and a second of the mounting tabs with the first and second mounting tabs separated by a cutout section therebetween.

14. The inflator bracket in accordance with claim 11, wherein the shelf forms a perimeter edge which is rolled over or radiused to prevent damage to the side curtain during a deployment of the side curtain airbag.

13. (canceled)
