摘要:
An inflator device includes a steel member to at least in part form a pressure vessel and an external composite wrap overlying at least a portion of the metal member. The metal member can be tubular and have an elongated length such as to form a steel inner liner that is incapable of withstanding the pressure generated within the pressure vessel upon actuation of the inflator device without support provided by the composite overwrap.
摘要:
An inflator including a housing with a first chamber that contains a quantity of gas generant. An initiator is operatively associated with the first chamber and in reaction initiating communication with at least a portion of the quantity of gas generant. The initiator, upon actuation, acts to ignite at least a portion of the quantity of gas generant to form gas. The housing further has a second chamber adjacently disposed to the first chamber. The second chamber contains a sealed storage reservoir and a piston assembly. The sealed storage reservoir includes a liner and a lid and contains a quantity of liquid. The piston assembly includes a piston. During deployment, the piston moves to unseal the storage reservoir to release at least a portion of the quantity of liquid such that the released liquid contacts and cools gas formed by the ignition of the gas generant. A discharge opening permits gas to exit the housing.
摘要:
A multi-stage inflator including a housing at least in part defining first and second combustion chambers each containing a quantity of gas generant reactable to form respective product gases. The inflator includes first and second initiators each operatively associated with a respective one of the combustion chambers in reaction initiating communication with at least a portion of the quantity of the gas generant therein contained such that upon actuation the gas generant ignites to form product gas. The second combustion chamber has an exit opening to allow product gas to exit from the second combustion chamber and into the first combustion chamber. The housing includes at least one discharge opening to permit gas to exit the housing and an end wall and wherein both the first and the second initiators are connected.
摘要:
An inflator that includes a quantity of gas generant housed within a chamber. A liquid including at least one of a fuel soluble in the liquid or an oxidizer soluble in the liquid and a piston are housed within another chamber of the inflator. This chamber is sealed. Upon actuation, movement of the piston hydraulically expels the liquid through an opening in the piston such that the liquid contacts the gas formed by combustion of the gas generant and cools the same. The fuel and/or oxidizer in the liquid can react to form additional gas.
摘要:
An inflatable cushion assembly for deployment in a vehicle. The assembly has an inflator, an inflatable cushion, and particles of a stop leak material. Upon deployment, the stop leak material becomes temporarily dispersed by and suspended in inflation gas such that the cushion is rendered less porous to inflation gas.

Disclosed are embodiments of an airbag tether release mechanism for use with airbag inflation systems. In one embodiment, the mechanism includes an initiator positioned within a housing. The initiator is configured such that it provides an inherent seal to prevent the external release of pyrotechnic residues upon deployment. The device may also include a cutter operatively connected with the initiator such that deployment of the initiator actuates the cutter and a tether restraint structure configured to secure a tether until the tether is released by actuation of the cutter.
摘要:
A filter for an inflatable vehicle occupant restraint inflator includes a tubular filter element having a generally cylindrical interior surface and a generally cylindrical outer surface having a predetermined diameter and a predetermined axial length and spaced radially outwardly from the inner surface. A tubular support member surrounds the outer surface. The support member is of an axial length equal to at least a major portion of the axial length of the outer surface and has an inner diameter substantially similar to the diameter of the outer surface for close surrounding engagement therewith. The support member has a plurality of through openings.
摘要:
A depth to which an inflatable airbag can deploy may varied by internal tethers. If the tethers are coupled to a release assembly, then in an unreleased state, the tethers can limit the depth of airbag deployment; however, if the tethers are released, the airbag can deploy of a full depth.
