Abstract:
PROBLEM TO BE SOLVED: To restrain the movement of a crew by having plural flow out ports for flowing out an expanded fluid and flowing in an expansion type vehicular crew restraint body on a cap and grasping a first gas supply cartridge to the base of a diffuser element by an assembly for supplying an expanded fluid. SOLUTION: A diffuser element 36 is formed by a cap and base. The disk type cap has a cylindrical side wall for defining a circular top wall and plural flow out port and opened circular bottom. An installation tightening tool, which is an installation nut, fixes first cartridge 34a and second cartridge 34b between the diffuser element 36 and a grasping bracket 42 by engaging with a related installation bolt tightly. When respective cartridges 34a, 34b are started, the expanded fluid is discharged from the discharge side of responding cartridges 34a, 34b to the diffuser element 36 through an installation flange.
Abstract:
PROBLEM TO BE SOLVED: To manufacture an air bag expansion device assembly in which a filter for reducing the internal pressure of an expansion device is obtained by winding a metal net material hollow cylindrical core in spiral to form a combustion inside tube. SOLUTION: A strip of wire mesh or expanded metal is cut in length matching with the diameter of a tube. A combustion filter tube is formed by winding three layers of wire woven fabric or expanded metal on a mandrel. Next, the tube is removed from the mandrel and is cut in prescribed length of a filter. The figure shows a completed passenger side combustion filter cut in prescribed length of 1' and having weld zones 21 at the tube end parts. The filter 20 has an inside diameter of 1.433" (3.64cm) and an outside diameter of 1.590" (5.04cm).
Abstract:
An assembly including a support housing and an actuator device (20). The actuator device (20) includes an extendable initiator cup (22) including at least one non-random fold (40) and at least in part defining a storage chamber (26) containing a reactive charge (28) reactable to produce reaction products. The extendable initiator cup (22) longitudinally extends from a first length to a second greater length upon reaction initiation of the reactive charge (28). The extendable initiator cup (22) is at least partially disposed within a longitudinally extending bore of the support housing (260). The support housing (260) is effective to limit lateral expansion of the extendable initiator cup (22) upon reaction initiation of the reactive charge (28). The assembly can include an electrical conductive member (250) or an electrical switch. The extendable initiator cup (22) can extend to sever the electrical conductive member (250) or disengage the electrical switch, thereby interrupting the conduction of electricity through an electrical system. Alternatively, the extendable initiator cup (22) can extend to engage the electrical switch thereby allowing the conduction of electricity through an electrical system.
Abstract:
A pyrotechnic inflator assembly including a shell member and an end cap joinable with the shell member to form a subassembly. The subassembly containing a quantity of pyrotechnic material and at least in part defining a combustion chamber wherein at least a portion of the quantity of pyrotechnic material is reactable to form product gas for inflation of an associated airbag cushion and to generate pressure within the combustion chamber. The inflator assembly further including an overwrap about at least a portion of the subassembly to form a pyrotechnic inflator assembly that withstands the pressure generated within the combustion chamber upon reaction of the pyrotechnic material.
Abstract:
An assembly including a support housing and an actuator device. The actuator device includes an extendable initiator cup including at least one non-random fold and at least in part defining a storage chamber containing a reactive charge reactable to produce reaction products. The extendable initiator cup is folded to form a pocket that contains a portion of a moveable element. The extendable initiator cup longitudinally extends from a first length to a second, greater length upon reaction initiation of the reactive charge. The extendable initiator cup and the moveable element are at least partially disposed within a longitudinally extending bore of the support housing. The extending initiator cup moves the moveable element within the bore. The support housing is effective to limit lateral expansion of the extendable initiator cup upon reaction initiation of the reactive charge.
Abstract:
A passenger airbag assembly having a first cushion and a second cushion is disclosed. An inflator mechanism that independently inflates the first cushion and the second cushion may also be added. The inflator mechanism may either be a dual stage inflator or two separate inflators. Preferably, the airbag assembly is designed such that the inflator mechanism begins the inflation of the first cushion prior to beginning the inflation of the second cushion. A housing may also be added to the airbag assembly. The housing encloses the inflator mechanism and is attached to the first cushion and the second cushion. The airbag assembly may be designed such that when the first cushion and the second cushion are inflated, the second cushion is positioned between the first cushion and the vehicle's windshield. Furthermore, the airbag assembly may also be made such that when the first cushion is inflated, the first cushion will push a vehicle occupant towards the vehicle's passenger seat.
Abstract:
An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes a tube that may be restricted to prevent gas venting. A cord is coupled to the tube and to a surface of the cushion. Upon airbag deployment, the cord extends until taut or extends until the cushion encounters an obstruction. If pulled taut, the cord tightens the tube and restricts gas venting. If the cushion encounters an obstruction, the cord remains lax and the tube is able to vent gas.
Abstract:
A modular fire detection and extinguishing system is disclosed that is inexpensive, compact, and modular to allow easy aftermarket installation in a variety of vehicles. The system may include a detector, a trigger coupled to the detector and a gas generant fire extinguisher, a modular distribution line in fluid communication with the extinguisher and a nozzle. The system allows exhaust gas from the gas generant fire extinguisher to carry dry powdered fire suppressant from the fire extinguisher and through the nozzle to disperse the fire suppressant substantially uniformly throughout a fire hazard zone. The extinguisher is installed such that exhaust gas must aerate substantially all the fire suppressant before exiting the extinguisher.
Abstract:
Un aparato de supresión de incendio incluye un alojamiento que define una primera cámara que contiene un generador de gas. El aparato además incluye un iniciador operativamente asociado con la primera cámara y en comunicación que inicia reacción con el generador de gas. El iniciador, con el accionamiento, actúa para encender al menos algo de generador de gas para formar gas. El alojamiento además define una segunda cámara dispuesta adyacentemente a la primera cámara. La segunda cámara contiene un material endotérmicamente alterable y un ensamble de pistón incluyendo un pistón. Con el accionamiento, el pistón se mueve para expulsar al menos una porción del material endotérmicamente alterable desde la segunda cámara para que el material endotérmicamente alterable expulsado contacte y enfríe gas formado por la ignición del generador de gas. El alojamiento además tiene al menos una abertura de descarga para permitir que el gas enfriado salga del alojamiento. También se proporcionan métodos correspondientes o asociados para suprimir un incendio.
Abstract:
Se proporcionan los dispositivos generadores de gas y los montajes relacionados, que incluyen cámaras de ignición y de generación de gas adyacentemente colocadas. Dentro de la cámara generadora de gas, está contenida una cantidad del material generador de gas, dentro de uno o más recipientes que tienen una pared lateral perforada y primera y segunda paredes extremas opuestamente colocadas. La primera pared extrema es perforada y colocada adyacente a la cámara de ignición para permitir la comunicación de al menos una porción de los productos de ignición a través de ésta, y en contacto con el material generador de gas contenido en ésta, para encender el material generador de gas para producir un producto gaseoso. La segunda pared extrema está perforada para permitir la comunicación de flujo de gas del gas producido a través de ésta, para descargarse desde el generador de gas.
