Abstract
Abstract A device for adjusting the inclination of a vehicle headlamp in a vertical plane between two predetermined directional settings to allow for variations in the longitudinal trim of a vehicle under different load conditions, independently of the normal adjustment of the headlamp directional setting. The adjusting screw which controls the rocking movement of the headlamp unit in a vertical plane engages a U-section elastic member which is snap-engageable by suitable elastic deformation into seats provided in the headlamp support plate selectively in two operative positions corresponding to the two predetermined headlamp settings.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
A motor vehicle headlamp assembly comprising a headlamp optical unit, an annular support plate surrounding said optical unit and connecting means for adjustably connecting said optical unit to said support plate, said connecting means including swivel means between said unit and said plate, aperture means in said support plate, at least one adjusting screw rotatably secured to said optical unit and an elastic U-shaped member having a central portion with a bore therethrough and two wings extending through said aperture means in operative engagement with said plate, said wings having two adjacent pairs of operatively disposed seats for selective engagement with said support plate to locate said elastic member in two different operative positions relative to said support plate, said screw being disposed in threaded engagement with said bore and extending through said aperture means to adjust the position of said unit relative to said elastic member and said support plate, and said elastic member being deformable to permit change over from one operative position to the other operative position to obtain two different inclinations of said unit relative to said support plate.
Claim 2
Dependent Claim
183 words
A motor vehicle headlamp assembly comprising a headlamp optical unit, an annular support plate surrounding said optical unit and connecting means for adjustably connecting said optical unit to said support plate, said connecting means including swivel means between said unit and said plate, aperture means in said support plate, at least one adjusting screw rotatably secured to said optical unit and an elastic U-shaped member having a central portion with a bore therethrough and two wings extending through said aperture means in operative engagement with said plate, said wings having two adjacent pairs of operatively disposed seats for selective engagement with said support plate to locate said elastic member in two different operative positions relative to said support plate, said screw being disposed in threaded engagement with said bore and extending through said aperture means to adjust the position of said unit relative to said elastic member and said support plate, and said elastic member being deformable to permit change over from one operative position to the other operative position to obtain two different inclinations of said unit relative to said support plate.
Claim 3
Dependent Claim
105 words
A motor vehicle headlamp assembly as set forth in claim 1 wherein said elastic U-shaped member is comprised of a plastics material with two wings having respective outer appendages connected to said central portion by means of transverse heel portions, two outwardly projecting lips at the free ends of said wings and two outwardly projecting opposed teeth on said wings, each tooth having an inclined surface facing toward the respective lip and the respective teeth defining with said lips and with said heel portions said two adjacent pairs of oppositely disposed seats in which said headlamp support plate engages selectively in said two operative positions.
Claim 4
Dependent Claim
35 words
A motor vehicle headlamp assembly as set forth in claim 1 further comprising a helical spring surrounding a portion of said adjusting screw intermediate said support plate and the central portion of said elastic member.
