Claim 5:
6. An actuator assembly comprising:
an actuator device comprising:
a tubular housing with a first end and a second end, the tubular housing defining a storage chamber 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 tubular housing is formed as a concave surface before actuation of the pyrotechnic material and during the actuation of the pyrotechnic material the second end is transitioned from the concave surface to a convex surface and maintains its integrity throughout the actuation; and

an assembly housing configured to house the actuator device, wherein the assembly housing comprises a reactive surface, wherein the second end of the tubular housing impacts the reactive surface during actuation of the pyrotechnic material, and wherein the assembly housing maintains its integrity throughout the actuation, wherein during the transition between the concave surface to the convex surface, the second end impacts the reactive surface of the assembly housing to displace the actuator within the assembly housing in a direction substantially opposite a direction of a displacement of the second end during the transition between the concave surface to the convex surface.
