Injection-molded plastic with a metal inlay replaces welded metal parts in an airbag gas generator ignition assembly, cutting cost, size, and weight.
Controlled resin cup elongation below 10% improves fire transfer to the enhance agent while preserving sealability and insulation.
A cage-type open fuel holder positions fibrous solid propellant at the igniter for faster, more reliable gas generation with lower manufacturing complexity.
Reversing combustion gas flow through an axial filter spreads residue more evenly, enabling a smaller gas generator without losing filtration performance.
