Airbag deflection mount
First Claim
1. An airbag deflection mount for mounting an airbag cushion to an airbag module, the airbag module also including an inflator having an inflator sidewall defining a plurality of spaced apart inflation ports, and a module baseplate surrounding the inflator sidewall below the plurality of inflation ports, with the airbag cushion including a throat surrounding the inflator sidewall and having a collar seated on the module baseplate so that inflation gas exiting the inflation ports of the inflator will inflate the airbag cushion, the airbag deflection mount comprising:
- a retainer ring receivable on the collar of the airbag cushion, the retainer ring securable to the module baseplate with the collar of the airbag cushion clamped therebetween; and
a plurality of circumferentially spaced-apart deflectors which, when the retainer ring is secured to the module baseplate, extend upwardly from the retainer ring to distal ends positioned between a top of the inflator sidewall and the plurality of inflation ports, with the plurality of deflectors deployed interposed between the inflator sidewall and the throat of the airbag cushion to deflect a substantial portion of hot inflation gas and hot particles exit the plurality of inflation ports of the inflator axially away from the throat of the airbag cushion while a lesser portion of the inflation gas passes radially past the spaced-apart deflectors to radially enter the airbag.

Abstract
An airbag deflection mount for mounting an airbag cushion to an airbag module and for deflecting hot inflation gas away from a throat of the airbag cushion. The airbag deflection mount includes a generally flat retainer ring for securing a collar of the airbag cushion around an inflator of the airbag module that produces and expels the inflation gas from a plurality of inflation ports for inflating the airbag cushion upon a vehicle collision. The airbag deflection mount also includes a plurality of deflectors extending upwardly from the retainer ring and positionable, spaced-apart from the inflator, between the plurality of inflation ports of the inflator and the throat of the airbag cushion. The plurality of deflectors deflect hot inflation gas away from the throat of the airbag cushion and substantially prevent the throat of the airbag cushion from being burned by the hot inflation gas.

11. An airbag module comprising:
-
A) an inflator having a sidewall defining a plurality of spaced-apart inflation ports; B) a module baseplate surrounding the inflator sidewall below the plurality of inflation ports; C) an airbag cushion including a throat surrounding the inflator sidewall and having a collar received on the module baseplate so that inflation gas exiting the inflation ports will inflate the airbag cushion; and D) an airbag deflection mount including, a retainer ring received over the collar of the airbag cushion and fastened to the module baseplate with the collar of the airbag cushion clamped therebetween, and a plurality of circumferentially spaced-apart deflectors extending upwardly from the retainer ring to distal ends between the plurality of inflation ports and a top of the inflator sidewall, the plurality of spaced-apart deflectors positioned between the inflator sidewall and the throat of the airbag cushion to deflect a substantial portion of hot inflation gas and solid particles exiting the plurality of inflation ports of the inflator axially away from the throat of the airbag cushion while a lesser portion of the inflation gas passes radially past the spaced-apart deflectors to radially enter the airbag. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
