Auto ignition package for an air bag inflator
First Claim
1. Apparatus for inflating an air bag comprising:
- means for defining a hermetically sealed housing;
gas generating material within said hermetically sealed housing which when ignited generates gas for inflating the air bag; and
an auto ignition packet within said hermetically sealed housing, said auto ignition packet comprising a container made of an air-permeable sheet material and auto ignition material which is enclosed within said container, said auto ignition material having an ignition temperature below the ignition temperature of said gas generating material.

Abstract
An inflator for inflating an air bag in a vehicle includes an inflator housing with an outer wall. A hermetically sealed canister is located in the housing. The canister has a first wall portion in thermal contact with the outer wall of the inflator housing. A body of gas generating material is disposed within the hermetically sealed canister. The gas generating material, when ignited, generates gas for inflating the air bag. An auto ignition packet including auto ignition material is secured within the hermetically sealed canister. The packet is in a recess in the canister in thermal contact with the first wall portion of the canister. The packet includes a flexible container, made of an air-permeable, fabric, sheet material, enclosing the auto ignition material.

20. In a method of making an air bag inflator having ignitable gas generating material, the steps comprising:
-
forming a cavity in a first piece of flexible non-metallic sheet material; depositing auto ignition material in the cavity, said auto ignition material having an ignition temperature below the ignition temperature of the gas generating material; attaching a second piece of flexible non-metallic sheet material to the first piece of flexible sheet material to close the cavity, thereby forming an auto ignition packet; and placing the auto ignition packet in a first member of a housing of the air bag inflator. - View Dependent Claims (21, 22, 23)
