Claim Text:
1. A chemical oxygen generator including an oxygen generating composition for producing a supplemental breathable gas when a reaction front propagates through the oxygen generating composition, the chemical oxygen generator comprising: a chemical oxygen generator housing having an ignition end and an opposing oxygen outlet end; a chemical core high reactivity section including an oxygen generating composition disposed in said chemical oxygen generator housing; first and second parallel sequentially connected chemical core sections disposed in said chemical oxygen generator housing, said first and second parallel sequentially connected chemical core sections each including an oxygen generating composition and having first ends oriented toward said ignition end of said chemical oxygen generator, second ends oriented toward said outlet end of said chemical oxygen generator, and body portions between said first and second ends extending a length along a longitudinal axis of said chemical oxygen generator housing, said first end of said first parallel sequentially connected chemical core section being disposed immediately adjacent to and contiguous with said chemical core high reactivity section; a thermal insulation layer disposed in said chemical oxygen generator housing between said first end of said second parallel sequentially connected chemical core section and said first end of said first parallel sequentially connected chemical core section, and between said body of said second parallel sequentially connected chemical core section and said body of said first parallel sequentially connected chemical core section; and a chemical core transition section including an oxygen generating composition disposed in said chemical oxygen generator housing between and immediately adjacent to and contiguous with said second end of said first parallel sequentially connected chemical core section and said second end of said second parallel sequentially connected chemical core section.
