Abstract

A simplified multi-chamber inflator 10 utilizes a housing 12 having two initiator chambers 42 and 44 respectively formed within an initiator assembly 18. The initiator assembly 18 may be formed from a one-piece component or alternatively, may be formed by coupling a first component 26 and a second component 28 in nested relationship within the housing 12. A primary propellant chamber 52 fluidly communicates with initiator chambers 42 and 44 upon actuation of inflator 10.
