Headlamp adjustment mechanism

An automotive vehicle headlamp mounting arrangement for connecting a reflector body of a headlamp with a panel of an automotive vehicle, the panel having an aperture rimmed on a side of the panel generally opposite the headlamp reflector body, the arrangement comprising:

• a screw with a first end engaging the reflector body and a second end extending toward the panel aperture;
• a retainer body having a base engaged with the vehicle panel in a nonrotative fashion, the retainer body having a head portion extending from the base encircling and mounting the screw, the retainer body having a central aperture generally aligned with the screw and the panel aperture;
• a barb piece having a central opening allowing penetration of the screw, the barb piece having a head nonrotatively engaged with the base of the retainer body and at least partially encircled thereby, the barb piece head having an outer threaded periphery, the barb piece also having extending from the head through the panel aperture a plurality of legs with outer gripping surfaces extending radially outwardly with respect to said screw for contacting an edge of the aperture rim generally opposite the headlamp reflector body;
• and
• a nut with a central aperture for passage of the retainer body head portion, the nut having inner threads engaging the barb outer threaded periphery of the piece head, causing the retainer body base to be clamped to the panel and the barb piece to be pulled toward the retainer body head and causing the gripping surface of the barb piece to be clamped against the panel aperture rim, thereby affixing the screw to the panel to affix the reflector body to the automotive vehicle.
