ABSTRACT:
An inflator (10) for an inflatable vehicle occupant protection device, such as an air bag, includes a housing (12) storing a non-pressurized source (16) of inflation fluid. The source (16) of inflation fluid is an elongated body (16) of ignitable material which, when ignited, generates combustion products including inflation gas and particulate matter. An imperforate tubular wall portion (20) of the housing (12) has an inner surface (66) extending fully along and around the elongated body (16) of ignitable material. The inner surface (66) functions to remove particulate matter from the inflation gas. The housing (12) further contains a tubular filter structure (120) formed of gas-permeable material for removing additional particulate matter from the inflation gas. The tubular filter structure (120) is substantially shorter than the elongated body (16) of ignitable material.
