GAS GENERATOR

摘要

A gas generator (10) has a polmeric closure (34) and an igniter subassembly (14) comprising an igniter (50) and a polymeric gas generator body (70). The gas generator body and the polymeric closure define a hermetically sealed combustion chamber (46) for receiving a gas generant (48). The igniter receives an electrical current and ignites the gas generant. The generated gas can be used in vechicle occupant safety devices including seat belt pretensioners, airbags, compressed gas vessel openers, and other devices requiring a rapid pulse of high-pressure gas.
