ABSTRACT:
An integrated gas strut actuator strut assembly particularly adapted for providing power actuation of a motor vehicle lift gate or other opening closure. The system integrates the function of a counterbalancing gas spring and that of a electrically powered actuator. The system incorporates a strut assembly including a gas charged cylinder, and 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. Another feature of the invention are various embodiments of couplers between the gas cylinder plunger and rod and connectors for the assembly to the vehicle.
