Abstract
An integrated gas strut actuator assembly particularly adapted for providing power actuation of a motor vehicle lift gate or other opening closure. 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. Other features of the invention are various embodiments of couplers between the plunger and rod and connectors for connecting the assembly to the vehicle.
