A first moving member is configured for receipt of a propulsive force emanating from the actuator upon actuation of the tether release system. A movable tether release member is contained within the housing wherein the movable tether release member operably communicates with the first moving member upon actuation of the tether release system, for release of an associated tether.

Abstract: A base assembly is provided for a gas generating system. The assembly includes a base having at least one opening formed therein, and an initiator assembly attached to the base so as to form a gas-tight seal surrounding the at least one opening. A retainer is attached to the base and includes an opening into which a portion of the initiator assembly extends. The retainer is attached to the initiator assembly along the retainer opening.

Abstract: A sub-assembly for a housing of a gas generating system is provided. The sub-assembly includes a housing portion and an insert attached to the housing portion such that at least a portion of a force applied to one of the housing portion and the attached insert is transferred through the attachment to the other one of the housing portion and the attached insert. A housing, a gas generating system, and a vehicle occupant protection system incorporating the sub-assembly are also disclosed.

Abstract: A gas generating system includes a housing with a first housing portion and a second housing portion configured to define a flow channel therebetween. The first housing portion includes a peripheral distension engageable with the second housing portion to form a sealed end of the flow channel.

Abstract: A releasable tether retention system includes a housing having a slot extending therealong and a projection extending into the slot. The projection is coupled to the housing so as to be movable along the housing between a first position along the slot and a second position along the slot. Rotation of the projection is prevented when the projection is in the first position, and rotation of the projection is enabled when the projection is in the second position.

Abstract: A gas generating system (10) including a filter assembly (36) formed from a plurality of nodules (36b) positioned and secured in relation to each other so as to form a porous structure (36a). In one embodiment, the nodules (36b) are metallic and are secured in relation to each other using either a sintering process or a brazing process. The nodules (36b) may be bonded directly together, or the nodules may be secured within a metallic matrix material. The gas generating system may also include a first baffle plate (40) positioned between the plurality of nodules (36b) and a gas source of the gas generating system (10), and a second baffle plate (42) positioned between the plurality of nodules (36b) and a housing wall (12c) of the gas generating system (10). The baffle plates (40, 42) provide added structural integrity to the porous structure (36a) and increase the length of a tortuous flow path of gases through the filter assembly (36).
