Abstract
Eine Basisanordnung für ein Gaserzeugungssystem wird bereitgestellt. Die Basisanordnung schließt eine Basis und eine Halterung ein, die an der Basis befestigt ist. In einer alternativen Ausführungsform schließt die Anordnung einen Initiator ein, der sowohl an die Basis als auch an die Halterung eingeformt ist.A base assembly for a gas generating system is provided. The base assembly includes a base and a bracket attached to the base. In an alternative embodiment, the assembly includes an initiator molded onto both the base and the bracket.
Description
HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
Die vorliegende Erfindung betrifft allgemein Gaserzeugungssysteme, welche einen pyrotechnischen Initiator zum Auslösen der Funktion eines Gaserzeugungssystems nutzen.The present invention relates generally to gas generating systems that utilize a pyrotechnic initiator to initiate the function of a gas generating system.
ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION
In einem Aspekt stellt die vorliegende Erfindung eine Basisanordnung für ein Gaserzeugungssystem bereit. Die Basisanordnung schließt eine Basis und eine Halterung ein, die an der Basis befestigt ist.In one aspect, the present invention provides a base assembly for a gas generating system. The base assembly includes a base and a bracket attached to the base.

Wieder unter Bezugnahme auf die
In einer speziellen Ausführungsform der Basisanordnung
Unter ”Einformen” des Initiators in die Basisanordnung, wie hierin beschrieben, ist zu verstehen, dass ein fließfähiges Gießmaterial, Klebematerial oder anderes Material, das eine Viskosität besitzt, die zum Spritzen, Gießen oder anderweitigem Einführen in das Gehäuse geeignet ist, in das Gehäuseinnere eingeführt wird, um einen Raum zwischen dem Initiator und dem Gehäuse zu belegen, nachdem der Initiator für die Zwecke der Gießoperation positioniert und gesichert wurde. Somit bilden die Basis und die Halterung einen Teil des Formkörpers. Das fließfähige Material, das sich in Kontakt mit der Basis, der Halterung und dem Initiator befindet, härtet aus oder verfestigt sich dann, um einen Teil des Initiators zu umschließen und den Initiator an der Basis und der Halterung zu sichern. Die verfestigte Formmasse kann auch eine gasdichte Dichtung zwischen der Basis und dem Initiator bilden.By "molding" the initiator into the base assembly as described herein, it is meant that a flowable casting material, adhesive material or other material that has a viscosity suitable for spraying, casting or otherwise inserting into the housing penetrates the housing interior is introduced to occupy a space between the initiator and the housing after the initiator has been positioned and secured for the purposes of the casting operation. Thus, the base and the holder form part of the shaped body. The flowable material in contact with the base, fixture and initiator then cures or solidifies to enclose a portion of the initiator and secure the initiator to the base and fixture. The solidified molding compound may also form a gas-tight seal between the base and the initiator.

Die
In den hierin offenbarten Ausführungsformen können die Formmassen zum Sichern des Initiators/der Initiatoren an die Basisanordnung ausgewählt sein, basierend auf solchen Faktoren wie gewünschtes Herstellungsverfahren, Systembetriebserfordernissen und anderen sachdienlichen Faktoren. Materialien wie Polymere, gießbare und injizierbare Klebstoffe und Einbettmassen und/oder jegliche andere geeignete Materialien können verwendet werden. Gießparameter wie Druck und Temperatur können iterativ bestimmt werden, basierend auf solchen Faktoren wie Formmassen und ausgewählten Verfahren, der Struktur der Form, in welche die Formmasse eingeführt werden soll und andere sachdienliche Faktoren.In the embodiments disclosed herein, the molding compositions for securing the initiator (s) to the base assembly may be selected based on such factors as desired manufacturing process, system operating requirements, and other pertinent factors. Materials like polymers, pourable and injectable Adhesives and potting compounds and / or any other suitable materials may be used. Casting parameters such as pressure and temperature can be determined iteratively, based on such factors as molding compositions and selected processes, the structure of the mold into which the molding material is to be introduced, and other pertinent factors.
