Abstract

An adjusting device for adjusting a light module in a vehicle lighting device. The adjusting device includes an adjusting mechanism into which a rotary motion can be transmitted. The adjusting device also includes a transmission element that can be used to transfer the rotary motion. The adjusting mechanism and the transmission element are connected in a way that transmits torque via a coupling that provides torque overload protection. The adjusting mechanism is embodied with at least two parts and features a first part into which a rotary motion can be transmitted and it features a second part that is embodied as a part of the coupling.

First claim

1 . An adjusting device for adjusting a light module in a vehicle lighting device, the adjusting device comprising:
an adjusting mechanism into which a rotary motion is transmitted, and a transmission element to transfer the rotary motion, where the adjusting mechanism and the transmission element are connected to transmit torque via a coupling for torque overload protection, and wherein the adjusting mechanism is embodied in at least two parts and has a first part into which the rotational movement is initiated and a second part, which is embodied as part of the coupling.

2 . The adjusting device in accordance with claim 1 , wherein the coupling has a metal spring element, which is embodied using the second part of the adjusting mechanism and
which includes at least one spring arm that, on the outside, surrounds a detent section embodied with a detent cam of the transmission element at least in sections.

3 . The adjusting device in accordance with claim 1 , wherein the first part of the adjusting mechanism is embodied in plastic and has a tool holder in which a tool for transmitting the rotary motion into the adjusting mechanism can be attached.

4 . The adjusting device in accordance with claim 2 , wherein the first part of the adjusting mechanism has a holder recess in which the spring element is placed in sections, where the holder recess, with reference to an adjustment axis, is embodied opposite to the tool holder in the first part of the adjusting mechanism.

5 . The adjusting device in accordance with claim 4 , wherein the spring element is introduced into the holder recess at a variable depth, where the spring arms have a greater spring rigidity at a deep installation depth and a smaller spring rigidity at a shallow installation depth.

6 . The adjusting device in accordance with claim 2 , wherein the spring element has a spring body that is manufactured from a press-bent component, where multiple spring arms are distributed along the circumference of the adjustment axis on the spring body.

7 . The adjusting device in accordance with claim 2 , wherein the spring arms have raised detents that face towards the detent cams, and the raised detents are oriented toward the detent cams.

8 . The adjusting device in accordance with claim 4 , wherein the spring element has at least one detent protrusion, which is engaged in at least one detent opening, where the detent opening is made in a wall of the adjusting mechanism that surrounds the holder recess.

9 . The adjusting device in accordance with claim 2 , wherein the transmission element is formed from a plastic and where the detent section is embodied in one part with the detent cams and in a uniform material with the transmission element.

10 . The adjusting device in accordance with claim 6 , wherein the spring body of the spring element is embodied in a rectangular design around an adjustment axis, and
where a holder recess features a cross section form in the shape of a rectangle around the adjustment axis.
