1. An inflatable airbag assembly comprising:
- an inflatable airbag;
an inflator coupled to the inflatable airbag, wherein the inflator comprises a tubular body with a gas-emitting end and an opposing connecting end,wherein the inflator comprises a first mounting stem and a second mounting stem,wherein the first mounting stem is located at the gas-emitting end that projects away from a long axis of the tubular bodywherein the second mounting stem is located at the connecting end that projects away from the long axis of the tubular body; and
,a metal heat shield coupled to the inflatable airbag such that an aperture in the inflatable airbag at least partially aligns with an aperture in the heat shield,wherein the inflator mounting stem protrudes through the aperture in the heat shield and the aperture in the inflatable airbag,wherein the heat shield is at least partially located between the gas-emitting end of the inflator and the inflatable airbag,wherein the heat shield is restricted to the gas-emitting end of the inflator, such that the heat shield does not extend to the second mounting stem and does not extend along an entire length of the long axis of the inflator, andwherein the heat shield has a length and thickness that permit the heat shield to be manipulated, without the use of a powered machine or powered tool, from a planar configuration to being at least partially wrapped around the gas-emitting end of the inflator such that the heat shield is coupled to the gas-emitting end of the inflator.

Abstract
Heat shields are used to shield an airbag from hot gasses issuing from an inflator. The heat shields can be a piece of thin metal that is coupled to the airbag cushion or the inflator. The heat shield can be held in place by being attached or coupled to the airbag and/or the inflator.
