Abstract: An inflatable restraint system inflator device having a housing defining an elongated chamber and containing an initial supply of stored inflation gas. An initiator is disposed proximate the first axial end of the housing and an operable closure is disposed proximate the second axial end of the housing. A slidable gas generator assembly is disposed within the chamber between the initiator and the closure and includes a supply of gas generant material reactable upon initiation to produce additional inflation gas. Upon actuation, the initiator and the slidable gas generator assembly cooperate to create a pressure wave to open the closure and to permit release of inflation gas. The slidable gas generator assembly slides within the elongated chamber and gas material reacts to form additional inflation gas.

Abstract: A hybrid inflator device for a passive restraint air bag system includes a housing defining a first chamber and a baffle passing through the first chamber. A supply of gas generant material is disposed in the first chamber and surrounds the baffle. An initiator is operative for creating a shock wave to open a burst disk and further operative to generate a hot gas to ignite the gas generant material. The initiator is disposed proximate a first end of the baffle. The baffle includes a reduced inner diameter portion and an unobstructed path extending along the length of the baffle.

Abstract: The present invention is directed to a system and method for providing complete electronic commerce (“E-Commerce”) transactions and solutions for a marketing company's products via the World Wide Web, including facilities for signing up new customers and recruiting, training and supporting new Independent Business Owners through an interactive online process. In another aspect, the present invention relates to the combination of a marketing business with a membership buying opportunity using both electronic commerce and face-to-face transactions. The present invention is also directed to a system and method for combining a marketing business with a membership buying opportunity, so that Independent Business Owners participating in the marketing plan can introduce customers to a membership buying opportunity and earn bonuses or commissions based on the purchases by those members, while Members in the buying opportunity can consume products or, at their option, qualify to become Independent Business Owners.

Abstract: A deployable inflator that includes a quantity of gas generant. The generant is designed to produce a supply of inflation gas during deployment of the inflator. The inflator includes a first burst disk and a second burst disk. The first and second burst disks are separated by a cavity. The inflator also includes an opening (or multiple openings). During deployment, the inflation gas flows into the cavity via the opening(s) and ruptures the first burst disk to allow inflation gas to escape the inflator. The second burst disk ruptures after the pressure in the cavity drops sufficiently below the pressure on the other side of the second burst disk. This inflator reduces the initial onset rate of deployment.

Abstract: An airbag inflator that includes a pyrotechnic material capable of producing a quantity of gas during deployment. The inflator also includes a filter. The filter may be an expanded metal filter that is wrapped about the pyrotechnic material. When this filter is wrapped about the pyrotechnic material, the filter forms a plurality of layers having holes that are a different size. This filter also includes a first set of barriers and a second set of barriers that are positioned exterior of the first set of barriers, the second set of barriers being offset from the first set of barriers. Gas passing through the filter will encounter the first set of barriers, be re-directed, encounter the second set of barriers, be re-directed, and then flow out of the filter.

Abstract: An inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device includes a supply of gas generant material disposed within a sealed chamber, and an initiator device in reaction initiation combination with the supply of gas generant material. A venting orifice connects the chamber to the surrounding ambient environment, and a rupturable seal seals the venting orifice. Upon reaction initiation of the gas generant material to produce inflation gas, the rupturable seal ruptures to vent the chamber to the ambient environment. A valve assembly can be disposed adjacent the venting orifice. A moveable valve piston, in combination with an actuator device, can block the venting orifice as needed to close the venting orifice and stop inflation gas venting. An optional tether release mechanism can be used in combination with the valve assembly to release a cushion tether upon closing of the venting orifice.

Abstract: Disclosed are methods for covering a weld line and structures used to cover a weld line. Embodiments of the method comprise covering a weld line, such as the weld line between components of an airbag inflator structure, with a protective sleeve. This allows jagged edges and whiskers created during the welding process to be covered. The protective sleeve may comprise an annular structure adapted to be fitted over the weld line.

Abstract: An inflator device for an inflatable restraint system. The inflator device includes a tubular body with a center discharge opening disposed in a center portion of reduced diameter. First and second end closures each join an initiator to a respective opposing end of the tubular body to define a sealed chamber. First and second generant housings are disposed within the sealed chamber, define generant chambers containing a supply of generant material and include a plurality of openings providing fluid communication between the generant chambers and the sealed chamber. Rupturable initiator seals are disposed between the initiators and a respective generant chamber. A supply of pressurized stored gas and the supply of generant material are disposed within the sealed chamber.

Abstract: An airbag module may have an inflator, a cushion, and a housing that contains the inflator and the cushion. The housing has an outer wall formed of a flexible material and a bracket designed to be attached to a vehicle. During deployment, the cushion is expelled out of the housing through the bracket. The inflator remains in the housing and inflation gas is conveyed to the cushion through the housing. The inflator may be retained by flaps wrapped around the inflator and secured to a perpendicularly oriented diffuser of the inflator. Alternatively, the diffuser may extend through an orifice formed in a fabric wall within the housing, and retention portions of the outer wall may be wrapped around the opposite side of the inflator. The airbag module may be mounted in an instrument panel to provide front seat, passenger's side impact protection without requiring a rigid module housing.

Abstract: A method for forming a complex hole through a wall of a structure. The complex hole has a smaller cross-sectional area within the wall and an outer portion with a larger cross-sectional area adjacent a first surface of the wall. The complex hole further has an inner portion extending between the smaller cross-sectional area and an inlet opening on a second surface of the wall. The method uses an EDM process to automatically first, form an entry hole in the wall extending from the first surface to a first location inside the wall, and second, form the outer portion of the complex hole in a direction moving from the first location inside the wall toward the first surface, and third, form the inner portion of the complex hole.

Abstract: An inflator apparatus for inflating an inflatable device and a method are provided which utilize a burst disk arrangement which results in a sequential opening regime such as may desirably provide a form of the above-described S curve inflation performance behavior without necessitating the use of or reliance on mechanical opening devices such as projectiles or piston members.

Abstract: The cost and ease of manufacture and assembly of airbag inflators is enhanced by welding sections of the inflator housing together in a recessed portion of the side wall of such housing. By providing a portion of the housing side wall which is recessed sufficiently that it contains all of the weld flashing produced during the welding operation it is possible to eliminate the machining operation for removing such flashing which, otherwise, could be required to provide external dimensions within specification.
