Abstract
An actuator is disclosed. The actuator includes: an output gear, a pinion, a drive shaft, a housing, and a spring. The output gear is adapted to receive a traction element. The pinion is in driving communication with the output gear. The drive shaft is interconnected with the pinion. The housing is adapted to receive the output gear and the drive shaft. The coil spring is circumjacent the drive shaft and located in a position intermediate the drive shaft and the housing, whereby rotation of the drive shaft causes the coil spring to frictionally disengage from the housing such that the output gear may rotate.
