Inflator having an ignition nozzle

摘要

An inflator ( 10 ) includes a container ( 12 ) having a chamber ( 120 ). An exit opening ( 48 ) is provided in the container ( 12 ) and is connected to the chamber ( 120 ). A substance ( 122, 180 ) is stored in the chamber ( 120 ) and is responsive to heat for providing inflation fluid. An igniter ( 130 ) is associated with the container ( 12 ) and is actuatable to provide combustion products for heating the substance ( 122, 180 ). A nozzle ( 80 ) is interposed between the igniter ( 130 ) and the chamber ( 120 ). A passage ( 90 ) extends from the igniter ( 130 ) and through the nozzle ( 80 ). The passage ( 90 ) includes a divergent portion ( 110 ) for focusing a flow of combustion products from the igniter ( 130 ) into the chamber ( 120 ).
