Patent ID: 7063019

Claim:
An assembly comprising: an actuator device including: an extendable initiator cup at least in part defining a storage chamber containing a reactive charge reactable to produce reaction products, the extendable initiator cup including at least one non-random fold; and at least one electrical connector in reaction initiating communication with the reactive charge; the extendable initiator cup having a first length prior to reaction initiation of the reactive charge and, upon reaction initiation of the reactive charge, the extendable initiator cup longitudinally extends to a second length, where the second length is greater than the first length; and a support housing including a longitudinally extending bore, the extendable initiator cup at least partially disposed within the bore; wherein the support housing is effective to limit lateral expansion of the extendable initiator cup upon reaction initiation of the reactive charge and wherein in the absence of the support housing, the extendible initiator cup ruptures upon reaction initiation of the reactive charge.
