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.

Abstract: A headlamp adjuster is provided for use and access from the front of a headlamp assembly on which it is installed. The adjuster includes an input shaft and an output screw in substantially parallel, spaced arrangement. A gear train drivingly connects inner ends of the input shaft and the output screw. Rotation of the input shaft about its longitudinal axis causes axial translation of the output screw.

Abstract: A headlamp adjuster and a headlamp adjustment assembly have a fixed annular boss, a shaft axially moveable through the boss, and a gear having a thread engagement with a threaded portion of the shaft. A cap is non-rotatably engaged with the shaft and the boss.

Abstract: A ball socket suitable for a headlamp adjustment assembly. The ball socket has a ring, a plurality of arches and outwardly directed tabs aligned with the arches. Panels between the arches each have outwardly directed ledges. Inwardly directed fingers are provided between the arches substantially aligned with the ledges.
