ABSTRACT:
An adjuster to be used with numerous applications including the adjusting of a headlamp reflector of a headlamp assembly includes a clutch mechanism that prevents over-driving and over-traveling of the adjuster output shaft during an overload condition. The adjuster includes generally an output shaft, drive gear, spring, and a driven gear that allow the headlamp adjuster to clutch. The driven gear is held in an engaged position with the drive gear by the spring force of the spring. In a high torque condition, such as when the output shaft encounters a high load, the driven gear will disengage from the drive gear overcoming the spring force of the spring. In this position, the headlamp adjuster will clutch, thereby preventing the over-driving and over-traveling of the output shaft.
