Patent number: 8491005Abstract: An inflator for producing inflation gas from a propellant has a housing for storing the propellant, a diffuser for attachment to the inflator housing and a sealing member. The diffuser has one or more open passages for passing inflation gas upon ignition of the propellant and a plurality of sealed passages oriented opposite to the one or more open passages. The sealing member covers the sealed passages. The sealing member is consumed when exposed to an open flame thereby opening the sealed passages to vent inflation gases opposite the opposed one or more open passages to create a thrust neutral exhaust upon an inadvertent ignition of the propellant due to exposure to fire.Type: GrantFiled: November 9, 2011Date of Patent: July 23, 2013Assignee: Key Safety Systems, IncInventor: David R Arnold
