Abstract

Abstract An occupant restraining inflatable cushion apparatus includes a gas generator which generates a hot gas to inflate an inflatable fabric cushion of nylon-like material which is packaged about the gas generator in a deflated condition. The improvement comprises at least a portion of the inflatable cushion closest to the gas generator being a fabric having high temperature resistive properties whereby the the high temperature generated by the gas generator is prevented from pyrolizing the inflatable cushion. The high temperature resistive fabric may be fashioned as a liner which wraps around a metallic heat shield and is interposed between the heat shield and the nylon-like fabric. Alternatively the inflatable cushion may be fabricated of two different types of materials with the high temperature resistive material being used in those areas closest to the gas generator and the conventional nylon-like fabric used for the remainder of the bag more distant from the gas generator.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 208 words
In combination, a cylindrical shaped gas generator including a cylindrical manifold containing chemicals for generating hot gas and having ports therein through which the hot gases exit the gas generator, a heat shield of cylindrical shape enclosing the gas generator and having an open end through which the cylinder may be inserted in to the heat shield and having portions of the heat shield spaced away from the gas generator to reduce the direct conduction of high temperature from the gas generator to the heat shield and having other portions of the heat shield contacting with the gas generator in order to provide a mounting relationship therebetween, an inflatable cushion of pyrolizible fabric tightly packaged about the heat shield in a deflated condition and being inflated by the hot gasses emanating from the gas generator, and a fabric of high temperature resistive properties carried by the inflatable cushion at least in those areas of the inflatable cushion contacting the heat shield and gas generator so that the high temperature of the gas generator and the high temperature conducted to the heat shield is experienced by the fabric of high temperature resistive property whereby the high temperatures generated by the gas generator are prevented from pyrolizing the inflatable cushion.
Claim 2
Dependent Claim 208 words
In combination, a cylindrical shaped gas generator including a cylindrical manifold containing chemicals for generating hot gas and having ports therein through which the hot gases exit the gas generator, a heat shield of cylindrical shape enclosing the gas generator and having an open end through which the cylinder may be inserted in to the heat shield and having portions of the heat shield spaced away from the gas generator to reduce the direct conduction of high temperature from the gas generator to the heat shield and having other portions of the heat shield contacting with the gas generator in order to provide a mounting relationship therebetween, an inflatable cushion of pyrolizible fabric tightly packaged about the heat shield in a deflated condition and being inflated by the hot gasses emanating from the gas generator, and a fabric of high temperature resistive properties carried by the inflatable cushion at least in those areas of the inflatable cushion contacting the heat shield and gas generator so that the high temperature of the gas generator and the high temperature conducted to the heat shield is experienced by the fabric of high temperature resistive property whereby the high temperatures generated by the gas generator are prevented from pyrolizing the inflatable cushion.
Claim 3
Dependent Claim 50 words
The combination of claim 1 further characterized by the fabric of high temperature resistive property being a piece of cloth which surrounds the gas generator and the heat shield and to which the inflatable cushion is joined at a point spaced away from the gas generator and the heat shield.
Claim 4
Dependent Claim 218 words
In combination, a cylindrical shaped gas generator including a cylindrical manifold containing chemicals for generating hot gas and having ports therein through which the hot gases exit the gas generator, a heat shield of cylindrical shape enclosing the gas generator and having an open end through which the cylindrical shaped gas generator may be inserted in to the heat shield and having portions of the heat shield spaced away from the gas generator to reduce the direct conduction of high temperature from the gas generator to the heat shield and having other portions of the heat shield contacting with the gas generator in order to provide a mounting relationship therebetween, an inflatable cushion of pyrolizible fabric tightly packaged about the heat shield in a deflated condition and being inflated by the hot gasses emanating from the gas generator, and a fabric liner of high temperature resistive properties carried by the inflatable cushion and sewn into the inflatable cushion at least in those areas of the inflatable cushion contacting the heat shield and gas generator so that the high temperature of the gas generator and the high temperature conducted to the heat shield is experienced by the fabric of high temperature resistive property whereby the high temperatures generated by the gas generator are prevented from pyrolizing the inflatable cushion.
