Abstract
Abstract A motor vehicle headlight comprising a light source, a reflector, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on the reflector in a plane which is essentially vertical and parallel to the optical axis defined by the reflector, the spirit level being in a predetermined angular relationship with the optical axis. The spirit level is mounted on a hollow support having an end edge suitable for bearing against the rear face of the reflector around a lamp mounted in the reflector.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A motor vehicle headlight comprising a light source, a reflector having a lamp supporting collar and a rear face, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on said reflector in a plane which is essentially vertical and parallel to the optical axis defined by said reflector, the spirit level being in a predetermined angular relationship with said optical axis, wherein the spirit level is mounted on a hollow support having an end edge which is mounted adjacent an indicator support collar means which abuts against the rear face of the reflector around a lamp mounted in the reflector and at a distance from said lamp supporting collar.
Claim 2
Dependent Claim
132 words
A motor vehicle headlight comprising a light source, a reflector having a lamp supporting collar and a rear face, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on said reflector in a plane which is essentially vertical and parallel to the optical axis defined by said reflector, the spirit level being in a predetermined angular relationship with said optical axis, wherein the spirit level is mounted on a hollow support having an end edge which is mounted adjacent an indicator support collar means which abuts against the rear face of the reflector around a lamp mounted in the reflector and at a distance from said lamp supporting collar.
Claim 3
Dependent Claim
33 words
A headlight according to claim 1, in which the end edge of said hollow support is mounted within said indicator support collar means and bears directly against the rear face of the reflector.
Claim 4
Dependent Claim
43 words
A headlight according to claim 1, in which the support further includes means at another end which, when said support is reversed through 180°; serve to fix the support on a rear opening of the headlight housing in order to close said housing.
Claim 5
Dependent Claim
40 words
A headlight according to claim 3, in which the support includes a generally cylindrical outside wall and an inside transverse partition, said outside wall being suitable for bearing against the rear face of the reflector and carrying the fixing means.
Claim 6
Dependent Claim
19 words
A headlight according to claim 4, in which the spirit level is fixed on the top of the support.
Claim 7
Dependent Claim
19 words
A headlight according to claim 3, in which the spirit level is fixed on the top of the support.
Claim 8
Dependent Claim
130 words
A motor vehicle headlight comprising a light source, a reflector, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on said reflector in a plane which is essentially vertical and parallel to an optical axis defined by said reflector, the spirit level being in a predetermined angular relationship with said optical axis, wherein the spirit level is mounted on a support suitable for bearing via a plurality of thrust surfaces against a set of associated reference surfaces fixed to the reflector, the device further including means for adjusting the position of at least one of said reference surfaces in a direction substantially parallel to the optical axis.
Claim 9
Dependent Claim
130 words
A motor vehicle headlight comprising a light source, a reflector, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on said reflector in a plane which is essentially vertical and parallel to an optical axis defined by said reflector, the spirit level being in a predetermined angular relationship with said optical axis, wherein the spirit level is mounted on a support suitable for bearing via a plurality of thrust surfaces against a set of associated reference surfaces fixed to the reflector, the device further including means for adjusting the position of at least one of said reference surfaces in a direction substantially parallel to the optical axis.
Claim 10
Dependent Claim
25 words
A headlight according to claim 7, wherein resilient means are also provided to take up any slack between the thrust surfaces and the reference surfaces.
Claim 11
Dependent Claim
18 words
A headlight according to claim 8, in which the position adjusting means comprise a screw and nut assembly.
Claim 12
Dependent Claim
18 words
A headlight according to claim 7, in which the position adjusting means comprise a screw and nut assembly.
