Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
A headlight adjusting device for a vehicle such as an automobile, comprising adjusting screws respectively arranged between one bearing at the vehicle and/or at a supporting frame mounted to the vehicle and one bearing associated with the headlight, said adjusting screws being secured in position without axial and transverse play in one of said bearings and held axially in fixed position and transversely in a movable position in the other of said bearings in that these other bearings holding said adjusting screws axially in fixed position and transversely in a movable position include elongate, slotted holes which receive said adjusting screws and permit transverse movement thereof during adjustment of said headlight, respective elastic elements in the form of spring clips being arranged between these other bearings and said adjusting screws to eliminate axial play between these other bearings and the adjusting screws while permitting transverse movement of the adjusting screws within the elongate, slotted holes of these other bearings during adjustment of said headlight.
Claim 2
Dependent Claim
164 words
A headlight adjusting device for a vehicle such as an automobile, comprising adjusting screws respectively arranged between one bearing at the vehicle and/or at a supporting frame mounted to the vehicle and one bearing associated with the headlight, said adjusting screws being secured in position without axial and transverse play in one of said bearings and held axially in fixed position and transversely in a movable position in the other of said bearings in that these other bearings holding said adjusting screws axially in fixed position and transversely in a movable position include elongate, slotted holes which receive said adjusting screws and permit transverse movement thereof during adjustment of said headlight, respective elastic elements in the form of spring clips being arranged between these other bearings and said adjusting screws to eliminate axial play between these other bearings and the adjusting screws while permitting transverse movement of the adjusting screws within the elongate, slotted holes of these other bearings during adjustment of said headlight.
Claim 3
Dependent Claim
58 words
The headlight adjusting device according to claim 1, wherein said adjusting screws are respectively arranged between one bearing at a supporting frame mounted to the vehicle with mounting means and one bearing associated with the headlight, and wherein the bearings at the supporting frame are located in the direct vicinity of the mounting means of the supporting frame.
Claim 4
Dependent Claim
55 words
The headlight adjusting device according to claim 1 or 2, wherein said headlight includes a reflector, means being provided for fixedly holding said reflector at a point and bearings for two adjusting screws being respectively arranged in a plane horizontal and a plane vertical with respect to said point at the periphery of the reflector.
Claim 5
Dependent Claim
26 words
The headlight adjusting device according to claim 3, wherein an adjusting member of an illuminating range adjusting means engages the adjusting screw in the vertical plane.
Claim 6
Dependent Claim

The headlight adjusting device according to claim 3, wherein the bearings for the two adjusting screws arranged at the periphery of said reflector are said other bearings and wherein the elastic elements are U-shaped spring clips slotted in the direction of their legs, the adjusting screws engaging in the slots of the spring clips with the spring clips resting on their associated screw and on the reflector adjacent said elongate, slotted holes of said other bearings.
Claim 7
Dependent Claim
68 words
The headlight adjusting device according to claim 1 or 2, wherein said other bearings are associated with the headlight and wherein the elastic elements are U-shaped spring clips slotted in the direction of their legs, the adjusting screws engaging in the slots of the spring clips with the spring clips resting on their associated adjusting screw and the headlight adjacent said elongate, slotted holes of said other bearings.
Claim 8
Dependent Claim
25 words
