Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A motor vehicle headlamp comprising: a first light source disposed within a main parabolic reflector, a secondary parabolic reflector, together with a second light source disposed therewithin, positioned within the main reflector, a pivotal connection provided between the secondary and main reflectors for allowing relative angular displacement therebetween, said pivotal connection comprising cooperating arcuate abutment surfaces, at least one of which is disposed on each reflector, readily releasable means for maintaining said cooperating abutment surfaces in contact, and an adjustment device for controlling the relative angular displacement of the secondary reflector with respect to the main reflector.
Claim 2
Dependent Claim
97 words
A motor vehicle headlamp comprising: a first light source disposed within a main parabolic reflector, a secondary parabolic reflector, together with a second light source disposed therewithin, positioned within the main reflector, a pivotal connection provided between the secondary and main reflectors for allowing relative angular displacement therebetween, said pivotal connection comprising cooperating arcuate abutment surfaces, at least one of which is disposed on each reflector, readily releasable means for maintaining said cooperating abutment surfaces in contact, and an adjustment device for controlling the relative angular displacement of the secondary reflector with respect to the main reflector.
Claim 3
Dependent Claim
97 words
A motor vehicle headlamp comprising: a first light source disposed within a main parabolic reflector, a secondary parabolic reflector, together with a second light source disposed therewithin, positioned within the main reflector, a pivotal connection provided between the secondary and main reflectors for allowing relative angular displacement therebetween, said pivotal connection comprising cooperating arcuate abutment surfaces, at least one of which is disposed on each reflector, readily releasable means for maintaining said cooperating abutment surfaces in contact, and an adjustment device for controlling the relative angular displacement of the secondary reflector with respect to the main reflector.
Claim 4
Dependent Claim
97 words
A motor vehicle headlamp comprising: a first light source disposed within a main parabolic reflector, a secondary parabolic reflector, together with a second light source disposed therewithin, positioned within the main reflector, a pivotal connection provided between the secondary and main reflectors for allowing relative angular displacement therebetween, said pivotal connection comprising cooperating arcuate abutment surfaces, at least one of which is disposed on each reflector, readily releasable means for maintaining said cooperating abutment surfaces in contact, and an adjustment device for controlling the relative angular displacement of the secondary reflector with respect to the main reflector.
Claim 5
Dependent Claim
47 words
A motor vehicle headlamp as claimed in claim 1, in which one of the cooperating abutment surfaces if formed by a semi-cylindrical projection extending from and integral with the secondary reflector, the other abutment surface being formed by a corresponding semi-cylindrical recess provided in the main reflector.
Claim 6
Dependent Claim
28 words
A motor vehicle headlamp as claimed in claim 2, in which said projection is provided with a radially extending stud projecting through an aperture in the main reflector.
Claim 7
Dependent Claim
39 words
A motor vehicle headlamp as claimed in claim 3, in which the readily releasable means comprises a resilient head provided on the end of the stud and adapted to be resiliently forced through the aperture in the main reflector.
Claim 8
Dependent Claim
41 words
A motor vehicle headlamp as claimed in claim 1, in which the readily releasable means comprises a resilient member mounted on the second reflector, said member being deformable to enable it to be passed through an aperture in the main reflector.
Claim 9
Dependent Claim
27 words
A motor vehicle headlamp as claimed in claim 1 including a pair of spaced, part-spherical projections on the secondary reflector, each projection presenting an arcuate abutment surface.
Claim 10
Dependent Claim
30 words
A motor vehicle headlamp as claimed in claim 6, in which the secondary reflector is provided between the projections with a stud extending through an aperture in the main reflector.
