Selectively heat treated airbag canister and method for making same |
摘要 |
A selectively heat treated canister for use in a vehicle airbag deployment system is configured to contain combustion materials and to contain gases produced from the combustion thereof. The canister includes a tubular body having a length and a longitudinal axis. The body is formed as at least three drawn sections. Each prior section is drawn one more time than a successive adjacent section. The canister defines a closed end and an open end. The closed end is at a least drawn section and the open end is at a most drawn section. The canister defines a heat treated region and is selectively heat treated at least one transition zone between adjacent drawn sections to reduce crack propagation observed during testing. A method for making the canister is also disclosed.
