Abstract
Abstract An orientable headlamp for motor vehicles wherein a first supporting member is located at the point of intersection of two orthogonal axes and is in a spatially fixed position, a second supporting member is screwably affixed into a fixed seating for the headlamp substantially parallel to the direction of the light beam, rotation of the lamp body about the second directional axis serving to adjust the position of the headlamp, and a third supporting member, a slider, is slidable in a direction which is parallel to the direction of the light rays, the slider being capable of being set in at least two positions remote from one another. It is thus possible, for example, to adjust the position of the headlamp consistently with variation of the vehicle load.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
244 words
Apparatus for supporting a headlamp in a seating of a motor vehicle to enable manual adjustment of the position of the headlamp, said apparatus comprising three support means connecting the headlamp to the seating, said three support means being positioned at the apices of a triangle which lies in a plane substantially perpendicular to the light beam from the headlamp, a first and second of said support means being on one side of said triangle which is substantially horizontal, the first and third of said support means being on a second side of said triangle which is substantially vertical, said first support means comprising a mounting member securing the headlamp to the seating such that the headlamp is pivotable thereat, said second mounting means comprising an aiming screw adjustably connecting the headlamp to the seating to pivotably displace the headlamp about said vertical side of said triangle, said third mounting means comprising a threaded member engaging said headlamp and displaceable in opposite directions to rotate the headlamp about said horizontal side of said triangle, actuator means threadably engaging said threaded member to move the same in either of said opposite directions by turning said actuator means, and means supporting said actuator means for displacement between first and second positions to carry said threaded member therewith and produce rotation of the headlamp about said horizontal side of the triangle, said first and second positions corresponding to two respective predetermined load conditions of the motor vehicle.
Claim 2
Dependent Claim

Apparatus for supporting a headlamp in a seating of a motor vehicle to enable manual adjustment of the position of the headlamp, said apparatus comprising three support means connecting the headlamp to the seating, said three support means being positioned at the apices of a triangle which lies in a plane substantially perpendicular to the light beam from the headlamp, a first and second of said support means being on one side of said triangle which is substantially horizontal, the first and third of said support means being on a second side of said triangle which is substantially vertical, said first support means comprising a mounting member securing the headlamp to the seating such that the headlamp is pivotable thereat, said second mounting means comprising an aiming screw adjustably connecting the headlamp to the seating to pivotably displace the headlamp about said vertical side of said triangle, said third mounting means comprising a threaded member engaging said headlamp and displaceable in opposite directions to rotate the headlamp about said horizontal side of said triangle, actuator means threadably engaging said threaded member to move the same in either of said opposite directions by turning said actuator means, and means supporting said actuator means for displacement between first and second positions to carry said threaded member therewith and produce rotation of the headlamp about said horizontal side of the triangle, said first and second positions corresponding to two respective predetermined load conditions of the motor vehicle.
Claim 3
Dependent Claim
19 words
Apparatus as claimed in claim 1 wherein said mounting member of the first support means comprises a set screw.
Claim 4
Dependent Claim
21 words
Apparatus as claimed in claim 1 wherein said actuator means comprises a rod with a threaded portion engaging said threaded member.
Claim 5
Dependent Claim
28 words
Apparatus as claimed in claim 3 wherein said means supporting the actuator means comprises a housing in which said rod is displaceable between said first and second positions.
Claim 6
Dependent Claim
