Abstract
Abstract A headlamp adjusting device for motor vehicles is disclosed; the device is operable to adjust the inclination of the headlamps with respect to the horizontal to compensate for changes in angle of the vehicle under two different load conditions. The device comprises an adjustable support for one of the normal adjusting screws of the headlamp, the adjustable support being movable between two positions by means of a control member having two wedge section limbs which are moved between the adjustable support and a fixed member in one position of the control member to define one position of the headlamps, and moved out from between the adjustable support and the fixed member in the other position of the control member to define the other position of the headlamps, to which latter position the headlamp is biased by a spring.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
269 words
In a headlamp of the type comprising an optical system, an annular support plate, three supports on said annular support plate, said optical system being mounted on said three supports, adjusting means on two of said three supports, said adjusting means each including an adjusting screw operating to adjust the inclination of the said headlamp in one of two planes, the improvement comprising an adjustment device for adjusting the inclination of the headlamp with respect to the horizontal to compensate for changes of inclination due to changes in load of the vehicle, said adjustment device comprising, a U-shaped support member, said U-shaped support member being slidably mounted for axial movement on said annular support plate, a threaded boss on said U-shaped support member, one of said adjusting screws engaging in said threaded boss, said adjusting screw controlling the inclination of said headlamp with respect to the horizontal, a rotatably mounted control member, said control member having two lateral projections, said lateral projections being wedge shaped in cross section and interposed between said U-shaped support member and said annular support plate, said control member being rotatable between two operating positions whereby in one said position of said control member said lateral projections cause relative axial separation of said U-shaped support member and said annular support plate by wedging them apart and in the other said position of said control member said lateral projections allow relative approach of said Ushaped support member and said annular support plate thereby adjusting the position of said adjusting screw to adjust the inclination of said headlamp with respect to the horizontal between two predetermined positions.
Claim 2
Dependent Claim
269 words
In a headlamp of the type comprising an optical system, an annular support plate, three supports on said annular support plate, said optical system being mounted on said three supports, adjusting means on two of said three supports, said adjusting means each including an adjusting screw operating to adjust the inclination of the said headlamp in one of two planes, the improvement comprising an adjustment device for adjusting the inclination of the headlamp with respect to the horizontal to compensate for changes of inclination due to changes in load of the vehicle, said adjustment device comprising, a U-shaped support member, said U-shaped support member being slidably mounted for axial movement on said annular support plate, a threaded boss on said U-shaped support member, one of said adjusting screws engaging in said threaded boss, said adjusting screw controlling the inclination of said headlamp with respect to the horizontal, a rotatably mounted control member, said control member having two lateral projections, said lateral projections being wedge shaped in cross section and interposed between said U-shaped support member and said annular support plate, said control member being rotatable between two operating positions whereby in one said position of said control member said lateral projections cause relative axial separation of said U-shaped support member and said annular support plate by wedging them apart and in the other said position of said control member said lateral projections allow relative approach of said Ushaped support member and said annular support plate thereby adjusting the position of said adjusting screw to adjust the inclination of said headlamp with respect to the horizontal between two predetermined positions.
Claim 3
Dependent Claim
44 words
The headlamp adjustment device of claim 1 wherein said limbs of said U-shaped support member are provided with resilient teeth, two slots in said annular support plate, said resilient teeth allowing snap-in assembly of said teeth into said slots in said annular support plate.
Claim 4
Dependent Claim
89 words
The headlamp adjustment device of claim 1 wherein said U-shaped support member is linked to one of said three supports of said optical system, said support comprising, a plate, said plate defining a substantially circular hole, a bracket secured to said plate, a shaped block secured to said bracket, said optical system resting against said shaped block, a pair of resilient teeth on said plate, a slot in said annular support plate, said resilient teeth allowing snap assembly of said support into said slot in said annular support plate.
Claim 5
Dependent Claim
31 words
The headlamp adjustment device of claim 1, a protuberance on said annular support plate, said control member cooperating with said protuberance to define said two oPerating positions of said control member.
