Abstract:
Abstract of DisclosureA cold gas generator for an airbag system has a storage device filled with a gas under pressure and provided with a gas outlet opening. A thin-walled sealing disk is provided which, in a rest state, seals pressure-tightly the gas outlet opening. A support device supports the sealing disk against a gas pressure of the gas acting on the sealing disk in a pressure direction. A triggering device acts on the support device. The support device has a pressure plate resting against the sealing disk and a support lever supporting the pressure plate and the sealing disk. The pressure plate and the support lever are configured as separate parts. A bearing supports the support lever such that the support lever receives forces in the pressure direction and is force-free transversely to the pressure direction. The triggering device acts on the support lever so as to cause pivoting about the bearing.
Abstract:
A system for controlling with safety the transfer or control of high pressure fluids from a container for use as to an inflatable escape slide. The pressurized container houses valve mechanisms such as a first and second valve mechanism, with the first valve mechanism controlling by actuation the on off flow of high pressure fluids to the second valve mechanism. The second valve mechanism controls the rate of flow by reducing the pressure for delivery to the inflatable escape slide. A safety valve operates in conjunction with the first valve mechanism and upon breaking of the valve mechanisms from the pressurized container to prevent the contents of the pressurized container from rapid escape or uncontrolled release.
Abstract:
A release device for releasing an inflatable element for protecting a vehicle against impact, which element, once inflated, presents a general shape that fits closely over the region of the vehicle to be protected, said inflatable element being held, in a folded state, in a compartment that includes a wall that is connected in sealed manner to an edge of an opening of said inflatable element, wherein, facing said opening, said wall includes gas release means that are protected during inflation of the inflatable element by a closure flap controlled by actuator means that remove said closure flap once the inflatable element is deployed.
Abstract:
An inflator (10) for providing inflation fluid to inflate an inflatable vehicle occupant protection device includes a pressure vessel (12) defining a chamber (30) for inflation fluid. The pressure vessel (12) has a passage (40) through which inflation fluid flows from the chamber (30). A burst disk (52) blocks fluid flow through the passage (40). A member (80) is disposed adjacent to and on one side of the burst disk (52) prior to the inflation fluid entering the pressure vessel (12). The burst disk (52) deforms toward the one side due to the pressure of the inflation fluid when the inflation fluid is disposed in the chamber (30). The member (80) limits deformation of the burst disk (52) by contacting the burst disk. An actuatable igniter assembly (66), when actuated, moves the member toward the burst disk (52) to rupture the burst disk and enable the inflation fluid to flow from the chamber (30) through the passage (40).
Abstract:
A release mechanism for releasing high pressure fluid from an associated pressure vessel has connecting means for connecting to the pressure vessel, a support sleeve which has an axial and a radial opening, a sealing disc, supporting means which may be a trap door, a rotatable column, or a support plug and a protractor or retractor for selectively removing the supporting means and thus opening the sealing means. The sealing means can also be opened spontaneously, operating as a relief valve.
Abstract:
In a fluid flow emergency shutdown valve a valve body is transversely interposed in a fluid line upstream with respect to a flow restricting unit, A valve stem is longitudinally slidably supported by the valve body and referenced to atmosphere at its respective ends, The valve stem supports a valve normally disposed upstream with respect to its seat. The other end portion of the valve stem supports a piston fluid pressure balanced by downstream fluid pressure from the outlet port of the flow restricting unit in combination with the buckling point value of a collapsible pin axially abutting the downstream end of the valve stem, A decrease in downstream fluid pressure below a predetermined value increases the pressure differential across the piston from its upstream to its downstream side which moves the piston to buckle the collapsible pin and move the valve to a closed position.
