The assembly integrates the function of a counterbalancing gas spring and that of a electrically powered actuator. The integrated gas strut assembly includes a gas charged cylinder, internal plunger and a threaded rod. Rotation of the threaded rod through a cable drive system causes the internal plunger to be advanced or retracted within the cylinder.
