Abstract:
An inflator ( 10 ) for a vehicle occupant restraint system. The inflator ( 10 ) includes a housing ( 12 ) having apertures ( 13 ) formed therealong to enable fluid communication between an interior of the housing ( 12 ) and an exterior of the housing. A first baffle ( 14 ) is positioned in the housing interior. The baffle ( 14 ) is spaced apart from the housing ( 12 ) to define a fluid channel ( 33 ) therebetween in communication with the housing apertures ( 13 ). The baffle ( 14 ) includes a first opening ( 17 ) for fluid communication between an interior of the baffle ( 14 ) and the fluid channel ( 33 ), and an open end portion for fluid communication between the baffle interior and the baffle exterior. A spacer ( 18 ) positioned in the housing interior cavity defines an enclosure ( 18 c) and includes an aperture ( 19 ) formed therein for fluid communication between the enclosure ( 18 c) and the open end portion of the baffle. A gas generant ( 30 ) is positioned within the spacer enclosure ( 18 c). The gas generant ( 30 ) may be a smokeless gas generant composition. An initiator ( 20 ) is coupled to the housing ( 12 ) for initiating combustion of the gas generant ( 30 ) upon activation of the inflator. The inflator ( 10 ) provides a continuous, tortuous fluid path through the fluid channel ( 33 ) for cooling inflation gases. In addition, the use of a smokeless gas generant composition allows the inflator ( 10 ) to operate without the need for a filter to remove particulate materials from the inflation gas.
