Claim 17:
18. An actuator device comprising:
an actuator cup comprising a first end and a second end, the actuator cup defining a storage chamber directly containing a pyrotechnic material to produce gas; and
at least one electrical connection coupled to the first end, the electrical connection in reaction initiating communication with the pyrotechnic material,
wherein the second end of the actuator cup comprises an inflection point, wherein actuation of the pyrotechnic material displaces the inflection point of the second end an axial distance away from the first end of the actuator cup,
wherein the second end of the actuator cup maintains its integrity during the displacement of the inflection point, and
wherein the gas produced by the pyrotechnic material does not escape the actuator cup; and

a tether that is looped around the actuator cup and is released from the actuator cup after actuation of the pyrotechnic material due to displacement of the actuator cup from a tether location.
