Abstract

The adjustment system comprises at least one pair of adjustment apparatuses. For each optical assembly, one adjustment apparatus is adapted to turn the optical assembly around the turning axis (α; β) independently of the other optical assembly. The adjustment system further comprises an additional adjustment apparatus connected to a first adjustment apparatus and adapted to transfer its movement to the movement of this adjustment apparatus; and a connecting member connected to the additional adjustment apparatus and to a second adjustment apparatus at the same time, and adapted to transfer the movement of the additional adjustment apparatus to the movement of the second adjustment apparatus (. If the additional adjustment apparatus is connected to the first adjustment apparatus and the connecting member is connected between the additional adjustment apparatus and the second adjustment apparatus, turning movement of one optical assembly will automatically induce a turning movement of the other optical assembly.

First claim

The invention claimed is:

1. An adjustment system of optical assemblies designed for motor vehicle headlights, wherein each of the optical assemblies is part of a separate lighting module, the adjustment system comprising at least one pair of adjustment apparatuses, wherein for each of the optical assemblies, one adjustment apparatus is designed and adapted to turn the optical assembly around a turning axis (α, β), the turning axis (α, β) of one of the optical assemblies being substantially parallel to a corresponding axis (α, β) of the other of the optical assemblies, wherein the adjustment system further comprises at least one additional adjustment apparatus that is connected to a first of the two adjustment apparatuses of a pair of adjustment apparatuses and adapted to transfer movement of the additional adjustment apparatus to the movement of the first adjustment apparatus, the adjustment system further comprising a longitudinal flexible connecting member that is connected to the additional adjustment apparatus and to a second of the two adjustment apparatuses and is adapted to transfer the movement of the additional adjustment apparatus through a twisting motion to the movement of the second of the adjustment apparatuses so that a turning of one optical assembly also causes simultaneous turning of the other optical assembly.

2. The adjustment system according to claim 1 , wherein the said simultaneous turning of the optical assemblies is turning by the same angle.

3. The adjustment system according to claim 1 , wherein the adjustment system comprises one pair of adjustment apparatuses and the turning axis (α) is substantially horizontal.

4. The adjustment system according to claim 1 , wherein the adjustment system comprises two pairs of adjustment apparatuses out of which one is adapted to turn the optical assemblies around substantially horizontal turning axes (α) and the other one is adapted to turn them around substantially vertical turning axes (β).

5. The adjustment system according to claim 4 , characterized in that the adjustment system comprises two connecting members.

6. The adjustment system according to claim 1 , wherein the connecting member is also adapted to transfer the movement of the second one of the adjustment apparatuses to the movement of the additional adjustment apparatus.

7. The adjustment system according to claim 1 , wherein the movement of the second one of the adjustment apparatuses and the movement of the additional adjustment apparatus is a rotary movement.

8. The adjustment system according to claim 7 , wherein the connecting member is fitted with gears for the transfer of the rotary movement.

9. The adjustment system according to claim 1 , wherein the connecting member is a cable.

10. The adjustment system according to claim 1 , wherein the adjustment apparatus comprises a shaft equipped at one end with a control member that can be used to set the shaft into a rotary movement in a controlled manner, the shaft being further equipped with a gear designed to transfer the torque between the additional adjustment apparatus and this adjustment apparatus, or between the adjustment apparatus and the connecting member, and in its opposite part with a thread to transfer the rotary movement of the shaft to a linear reciprocal movement of a slider.

11. The adjustment system according to claim 10 , wherein the slider comprises a nut and a central body at the outwardly oriented end of which a ball journal is situated to transfer the linear movement of the slider to a turning movement of the optical assembly around the turning axis (α, β).

12. The adjustment system according to claim 1 , wherein both the adjustment apparatuses of the pair of adjustment apparatuses have the same structure.

13. The adjustment system according to claim 12 , wherein all the adjustment apparatuses included in the adjustment system have the same structure.

14. The adjustment system according to claim 1 , wherein the additional adjustment apparatus comprises a shaft equipped with a top gear adapted to transfer a torque to the connecting member, and with a bottom gear adapted to transfer a torque to the gear of the adjustment apparatus, wherein the gear is coupled to a control member of the adjustment apparatus, and the additional adjustment apparatus is fitted at a top end of the additional adjustment apparatus with a control member for a controlled turning of the shaft.
