Claim:
1. An actuator comprising: a housing having an inner wall extending between a first end portion and a second end portion of the housing, the inner wall having a constant diameter between the first and second end portions, the second end portion defining an opening, and a diameter of the opening adjacent an inner surface of the second end portion is less than the diameter of the inner wall; an initiator for providing pressurized gas to the housing, the initiator being secured adjacent the first end portion of the housing; a piston movably disposed within the housing, the piston having a first side axially opposing a second side, the second side of the piston defining a first piston cavity that extends through the second side of the piston toward the first side of the piston terminates short of the first side of the piston, and the first side of the piston defining a second piston cavity; and a piston rod having a first end and a second end, the piston rod being separately formed from the piston; wherein the opening defined by the second end portion of the housing permits insertion of the first end of the piston rod into the opening, then into the first piston cavity, and the first end of the piston rod has a diameter approximating a diameter of the first piston cavity, and wherein a diameter of a distal of the second side of the piston is greater than the diameter of the opening defined by the second end portion of the housing, and wherein the initiator has an end disposed within the second piston cavity.
