Abstract

An actuator assembly that includes an actuator device. The actuator device includes 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. At least one electrical connection is coupled to the first end, the electrical connection in reaction initiating communication with the pyrotechnic material. An actuator housing that partially encompasses the tubular housing, wherein an outer surface of the actuator housing comprises a hexagon shaped portion that extends along a longitudinal direction of the actuator housing. An assembly housing at least partially encompasses the actuator device, wherein an inner surface of the assembly housing comprises an engaging surface portion that extends along a longitudinal direction of the assembly housing that corresponds to and slidably engages with the hexagon shaped portion of the actuator housing.
