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

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, comprising at least one pair of adjustment apparatuses wherein for each of the optical assemblies, one adjustment apparatus is designed, which is adapted to turn the optical assembly around a turning axis (α; β) independently of the turning of the other optical assembly, the turning axes (α, β) of the optical assemblies being substantially parallel to each other, wherein it further comprises at least one additional adjustment apparatus that can be connected to the first of the two adjustment apparatuses and is adapted to transfer its movement to the movement of this adjustment apparatus; and a connecting member that can be connected to the additional adjustment apparatus and to the second of the two adjustment apparatuses at the same time and is adapted to transfer the movement of the additional adjustment apparatus to the movement of the said second one of the adjustment apparatuses, wherein if the additional adjustment apparatus is connected to the first one of the two adjustment apparatuses and the connecting member is connected between the additional adjustment apparatus and the said second one of the two adjustment apparatuses, a turning movement of one optical assembly will automatically induce a turning movement 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 it comprises one pair of adjustment apparatuses and the turning axis (α) is substantially horizontal.

4 . The adjustment system according to claim 1 , wherin it 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 it comprises two connecting members.

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

7 . The adjustment system according to claim 6 , 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.

8 . The adjustment system according to claim 6 , wherein the movement of the second one of the adjustment apparatuses and the movement of the additional adjustment apparatus is rotary movement.

9 . The adjustment system according to claim 1 , wherein the connecting member is fitted with gears for the transfer of the rotary movement.

10 . The adjustment system according to claim 1 , wherein the connecting member is flexible.

11 . The adjustment system according to claim 10 , wherein the connecting member is a cable.

12 . 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.

13 . The adjustment system according to claim 12 , 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).

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

15 . The adjustment system according to claim 14 , wherein all the adjustment apparatuses included in the adjustment system have the same structure.

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