Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
An adjustment device for adjusting a reflector of a motor vehicle headlight relative to a fixed portion of said headlight; the device comprising an adjustment screw that includes a ball member received in a seat in a first element connected to one of said reflector and fixed portion and having a threaded portion engaging a threaded opening in a second element connected to the other of said reflector and fixed portion, wherein a first snap-fit fastening means is provided between one of said first and second elements and one of said reflector and said fixed portion, and a second snap-fit fastening means is provided between another of said first and second elements and the other of said reflector and said fixed portion, said first and second snap-fit fastening means being engageable by displacement of said first and second elements relative to said reflector and said fixed portion in directions generally parallel to each other.
Claim 2
Dependent Claim
154 words
An adjustment device for adjusting a reflector of a motor vehicle headlight relative to a fixed portion of said headlight; the device comprising an adjustment screw that includes a ball member received in a seat in a first element connected to one of said reflector and fixed portion and having a threaded portion engaging a threaded opening in a second element connected to the other of said reflector and fixed portion, wherein a first snap-fit fastening means is provided between one of said first and second elements and one of said reflector and said fixed portion, and a second snap-fit fastening means is provided between another of said first and second elements and the other of said reflector and said fixed portion, said first and second snap-fit fastening means being engageable by displacement of said first and second elements relative to said reflector and said fixed portion in directions generally parallel to each other.
Claim 3
Dependent Claim
18 words
A device according to claim 1, wherein said directions are essentially perpendicular to the axis of the screw.
Claim 4
Dependent Claim
50 words
A device according to claim 1, wherein the ball member is provided in an intermediate region of the screw situated between a drive knob and the threaded portion, and wherein the ball seat is defined between two branches of said first element, said branches defining a passage for the screw.
Claim 5
Dependent Claim
20 words
A device according to claim 1, wherein the screw includes other drive means at an end adjacent said threaded portion.
Claim 6
Dependent Claim
34 words
A device according to claim 1, wherein said first snap-fit fastening means include tab means on said first element and a correspondingly shaped zone of said one of said reflector and said fixed portion.
Claim 7
Dependent Claim
40 words
A device according to claim 1, wherein said second snap-fit fastening means are arranged so as to provide said threaded opening with a degree of pivoting movement about an axis that is generally perpendicular to the axis of said screw.
Claim 8
Dependent Claim
53 words
A device according to claim 6, wherein said second element includes oppositely projecting studs suitable for engagement in complementary openings provided in two surfacing faces of said other of said reflector and said fixed portion, entrance ramps adjacent said openings, the studs extending essentially perpendicular to the axis of the screw after assembly.
Claim 9
Dependent Claim
40 words
A motor vehicle headlight comprising at least one adjustment device according to claim 1, whereby a reflector is capable of being adjusted in orientation relative to a fixed portion such as an intermediate part between the reflector and a glass.
Claim 10
Dependent Claim
25 words
A headlight according to claim 8, wherein said first element is mounted on said reflector and said second element is mounted on the fixed portion.
Claim 11
Independent Claim
232 words
A method of assembling an adjustment device on a headlight that includes a reflector capable of being adjusted in orientation relative to a fixed portion such as an intermediate part between the reflector and a glass, said adjustment device comprising an adjustment screw that includes a ball member received in a seat connected to one of said reflector and fixed portion and a threaded portion engaging a threaded opening on the other of said reflector and fixed portion, wherein the ball seat and the threaded opening are respectively provided on first and second elements, first snap-fit fastening means are provided between one of said elements and one of said reflector and said fixed portion, and second snap-fit fastening means are provided between another of said elements and the other of said reflector and said fixed portion, said first and second snap-fit fastening means being engageable by displacement of said first and second elements relative to said reflector and said fixed portion in directions generally parallel to each other, the method comprising the following steps: (a) positioning the reflector and the fixed portion in a predetermined mutual relationship; (b) pre-assembling the screw with each of the two elements of the adjustment device; and (c) mounting said elements on said reflector and said fixed portion by displacement of said pre-assembled screw and first and second elements relative to said reflector and said fixed portion.
Claim 12
Independent Claim
232 words
A method of assembling an adjustment device on a headlight that includes a reflector capable of being adjusted in orientation relative to a fixed portion such as an intermediate part between the reflector and a glass, said adjustment device comprising an adjustment screw that includes a ball member received in a seat connected to one of said reflector and fixed portion and a threaded portion engaging a threaded opening on the other of said reflector and fixed portion, wherein the ball seat and the threaded opening are respectively provided on first and second elements, first snap-fit fastening means are provided between one of said elements and one of said reflector and said fixed portion, and second snap-fit fastening means are provided between another of said elements and the other of said reflector and said fixed portion, said first and second snap-fit fastening means being engageable by displacement of said first and second elements relative to said reflector and said fixed portion in directions generally parallel to each other, the method comprising the following steps: (a) positioning the reflector and the fixed portion in a predetermined mutual relationship; (b) pre-assembling the screw with each of the two elements of the adjustment device; and (c) mounting said elements on said reflector and said fixed portion by displacement of said pre-assembled screw and first and second elements relative to said reflector and said fixed portion.
Claim 13
Dependent Claim
29 words
A method according to claim 10, wherein step (c) is performed by moving the preassembled screw and elements in a direction substantially perpendicular to an axis of the screw.
