摘要： A fire suppression device (210) includes an enclosure (212) having opposite end walls (214, 216) and a side wall (218) joining the end walls to define a hollow chamber (220) within the enclosure. An atomizing nozzle (222) is operatively coupled to a first of the end walls and has an entrance portion (224) adjacent the chamber and an exit (225) in communication with the atmosphere outside of the enclosure. A frangible barrier (226) is interposed between the nozzle entrance portion (224) and the chamber and is responsive to a predetermined pressure for fracturing to permit communication between the nozzle and the chamber. A piston (232) is located between the end walls and engaged about an inner periphery of the side wall (218) to divide the chamber into two sections. A first of these sections (228), between the piston and the first end wall (214), is filled with a quantity of water and comprises a major fractional portion of the volume of the chamber. The piston is slidably moveable relative to the side wall (218) in the direction of the first end wall (214) in response to a force exerted upon the piston for exerting pressure upon the quantity of water for initially fracturing the frangible barrier and for thereafter delivering a water mist through the atomizing nozzle. A gas generator (240) communicates with the second section (230) for delivering high pressure gas to exert the force upon the piston, causing a fine mist to flow from the nozzle. As a variation, a conduit (250) may extend from the nozzle to the second section, and the nozzle may include venturis (252, 254) extending between the first section and the conduit. The generated gas will flow through the conduit to further draw the water via venturi effect.

摘要： A heat-enhanced inflator (10) for vehicle airbag inflation includes a housing (12) with a cylindrical sidewall (22) enclosing a gas storage chamber (30) and a heating cup (14) containing heat producing material (15). The heating cup has concentric inner (26) and outer (24) walls between which longitudinal passages (52) in the heat producing material (15) constitute gas delivery passages. When a squib (56) ignites igniter material (58) and rapid deflagration cord (60) the heat producing material is actuated and a diaphragm (42) in the heating cup ruptures to allow pressurized gas to pass through the heating cup (14) via openings (36, 38, 16). The heating cup may be centrally located in an elongate housing and may be confronted by ignition means arranged to directly rupture the diaphragm to allow gas into the heating cup. Such rupture may be assisted by a projectile.

摘要： The amount of particulate matter that is forced into the passenger compartment of an automobile by the deployment of an air bag as it protects the lives of occupants is reduced by improving the filterability of the combustion products of a composition for generating gas to inflate the bag. The filterability is improved by adding a nucleating agent for alkali metal halide vapors formed during said combustion. Silica, alumina, and graphite are representative of the nucleating agents.

摘要： An airbag inflator (10) with venturi effect cooling and gas supplement. The inflator includes a housing (14) having a quantity of gas-producing fuel (26) therein, and possibly a stored gas also, along with appropriate igniters (32). These materials are stored within a gas production chamber (24) of the housing. The gas leaving this chamber travels through the housing to an exit port (52) on the housing. Intermediate the gas production chamber and the housing exit port is a venturi section (38) of the housing. This section reduces the pressure of the gas, and thus the pressure at the interior end of draw vents (46) opening onto the venturi section. The vents therefore draw outside air into the housing to mix with the gas. This cools the gas to the desired temperature, and also supplements the gas exiting the housing. As such, the need for a heat sink to cool the gas is reduced or eliminated. Furthermore, since the cushion is inflated with a mixture of gas and air, the amount of gas typically needed is reduced by the amount of added air. This permits the amount of fuel to be reduced, thus reducing cost and weight.

摘要： Vehicle airbag inflator including a container (12) accommodating a source of gas and a cylindrical diffuser (16) inside which a piston (60) with a curved pintle surface (62) is slidable against the force of a compression coil spring (70). When pressure within the container rises above a threshold value a burst disc (22) ruptures permitting gas to pass into an opening (24) and flow over the pintle surface (62) causing the piston to uncover gas outlet openings (40) in the diffuser (16). A piston guide pin (54) connected to a guide base (52) engages a cylindrical bore (68) in the piston (60). The gas source may include a store of pressurised gas, combustible gas generating material or a combination of both. The inflator can be designed to provide a customised, non-linear control of the flow of gas from the inflator.

摘要： A hybrid inflator (10) for an inflatable restraint system has a center frame (12) and two tubular end caps (14,16) forming an elongated housing (11) defining a chamber (28) storing pressurized inert gas. Units (18,20) for heating and delivering the stored gas are mounted in the center frame and positioned to deliver inflation gasses centrally with respect to the elongated housing. In a two unit embodiment, one unit (18) includes a squib (42) and a pyrotechnic gas generant (54), and the other unit (20) defines an outlet orifice (22) and baffle plate (60). In another two unit embodiment, the second unit includes an essentially non gas-producing heating composition which, when activated, heats and expands the pressurized gas. In a third embodiment, a unit includes heating material and ignition means and defines the outlet orifice. The centre frame (12) is extruded metal stock with two opposing flat surfaces adapted to mount one or more units.

摘要： Electrolytic decomposition in a fuel cell (24) produces two products which can be recombined to produce heat useful in the inflation of an automotive airbag system in which a stored gas is heated while it is inflating the airbag. A preferred electrolytic solution (26) is aqueous. This is readily replenishable so that the heat producing electrolysis products are always available.
