Abstract
A disclosed drive assembly is suitable for driving an actuatable component in a first direction and a second direction. The drive assembly includes a housing and a drive rod. The drive rod selectively extends and retracts to apply a driving force to the actuatable component in a first and a second direction, respectively. The driving force creates a reactive force on the housing. An override assembly includes a spring in communication with the housing. The housing pushes a first end of the spring toward a second end of the spring when the reactive force exceeds a predetermined limit and the drive rod applies the driving force in the first direction. The housing pulls the second end of the spring toward the first end of the spring when the reactive force exceeds the predetermined limit and the drive rod applies the driving force in the second direction.
