    Adjustment system for a vehicle headlight
    The invention relates to an adjustment system for a vehicle headlight for adjusting an optically relevant component of the vehicle headlight, in which adjustment system of the optically relevant component to a) a fixed bearing point about a first and a second axis, preferably a vertical and a horizontal axis is pivotable, wherein the first and the second axis are normal to each other, b) the adjustment system comprises a first adjusting means by which the optically relevant component is pivotable about the first axis, wherein the first adjusting device acts on a second adjusting bearing point, and wherein c) the adjustment system comprises a second adjusting device, by means of which the optically relevant component is pivotable about the second axis, wherein the second adjusting device acts on a first adjusting bearing point, and wherein the fixed bearing point and the second adjusting bearing point form the second axis ,
    Furthermore, the invention relates to a vehicle headlamp with at least one optically relevant component and with at least one adjustment system for adjusting the at least one optically relevant component.
    Examples of such optically relevant components are diaphragms (arrangements), light sources, reflectors, lenses, entire light modules or modules, etc.
    Vehicle headlights are used to visualize the vehicle environment as well as the vehicles themselves. In addition, vehicle headlights are an integral part of the vehicle design, which can increase the recognition value of a make or a model. Modern vehicle headlamps have adjusting devices that allow, for example, manual factory optimization of a light projected onto a road. Furthermore, vehicle headlamps often additionally have headlamp leveling, which is controlled by an electric motor and can be operated by the vehicle driver in a simple manner, for example, or can be carried out automatically. The optically relevant component is usually pivotable about two mutually normally oriented axes, which, for example, the light range and a "left-right orientation" of the optically relevant component can be regulated. The two axes usually run through a common fixed bearing point and in each case one adjusting bearing point.
    A vehicle headlight with such an axle arrangement has become known, for example, from DE 10152931 A1. A triangle formed by the three bearing points lies in a vertical plane, with which a pivoting movement about the horizontal axis is associated with a substantially horizontal movement acting on an adjusting bearing point. Concomitant design requirements for the arrangement of actuators require a lot of space, and / or increase the manufacturing and material costs of a headlight housing.
    An object of the invention is an adjustment system for a vehicle headlamp for
    Adjustment of an optically relevant component of the vehicle headlamp to create, which in contrast to the prior art, a compact and space-saving design of the vehicle headlamp with a Verstelldreieck permits.
    This object is achieved with a setting system according to the aforementioned type, in which according to the invention the triangle formed by the three bearing points in the installed state of the headlight is substantially in a horizontal plane. The triangle formed from the three bearing points (also referred to as the adjustment triangle) is thus arranged to save space, which material savings and a freer design of a vehicle headlamp are possible with an adjustment system according to the invention.
    In a further development of the invention, it is provided that the second adjusting device comprises a manually operable first actuating means and that an electromotive second actuating means is provided, wherein the electromotive second actuating means is engaged with the optically relevant component for pivoting about the second axis. Pivoting about the second axis may be effected by a user inside the car via control signals or automatic headlamp leveling, e.g. provided on headlamps with xenon lamps, done. The second axis is preferably a horizontal axis, whereby the second adjusting means can be used to regulate the headlamp range of the headlamp. In a particularly simple and robust refinement of the invention, a setting direction of the first actuating means substantially coincides with a setting direction of the second actuating means.
    According to a first variant of the invention, the fixed bearing point is provided on a projecting from a housing rear side of a headlight housing strut, whereby the fixed bearing point can be formed particularly simple. The strut can be made in one piece with the headlight housing. The headlight housing in this case comprises the optically relevant component, the first and the second adjusting device and the second actuating means.
    In a further development of the first variant, an actuating element assigned to the second adjusting means and movable translationally in a setting direction is provided, wherein the actuating element engages with a arm pivotable about a third point on a first arm portion and a second arm portion of the arm with the optical relevant component or with a frame carrying the optically relevant component for pivoting about the second axis is engaged. The second actuating means can therefore be largely independent of the first adjusting element, together with the associated actuating element.
    Bearing point can be placed by the translational movement of the actuating element is transmitted via the second arm portion on the optically relevant component or the frame.
    In an additional development of the first variant of the arm is L-shaped, wherein the first and the second arm portion within opposing
    End portions of the arm are located. The movement of the actuating element can thereby be transmitted to the optically relevant component or the frame in a particularly efficient manner.
    The adjustment direction of the second actuating means advantageously forms a tangent to a circular path whose center lies in the fixed bearing point and whose diameter corresponds to the distance between the fixed bearing point and the first adjusting bearing point.
    According to a second variant of the invention, the second adjusting means for adjustment by the first adjusting means is movably mounted on a first guide located on a rear side of the housing. A permanent adjustment of the second actuating means is thus particularly easy to influence without affecting the adjustment of the second actuating means. In a third variant, the fixed bearing point is provided on a strut extending from a housing upper side of a headlight housing to a housing underside of the headlight housing. In this variant eliminates a connection of the strut with the back of the case, which is the space between the back of the case and the strut is useful. For example, the second adjusting means may be arranged between the strut and the rear side of the housing.
    In a further development of variants two and three, an adjusting element assigned to the second adjusting means and movable translationally in a setting direction is provided, wherein the adjusting element engages with a transmission element movably guided on a second guide, wherein the second guide is stationary with the second actuating means is connected, wherein the optically relevant component is received in a frame, and the optical relevant component is pivotable together with the frame about the first and the second axis, wherein an end region protruding from the frame has a connecting piece, which at least partially in an opening region of the transmission element is received. The structure of the adjustment is thus particularly robust and space-saving.
    According to a fourth variant of the invention, the strut has a suspension element, which is adapted for the articulated receiving a support arm, wherein the second adjusting means is fixedly connected to the holding arm, wherein the first adjusting means with the holding arm for pivoting the support arm with respect to the suspension element in
    Intervention is. The position of the second actuating means can thus be changed in a simple manner with the aid of the first actuating means.
    In a further development of the fourth variant, the first actuating means is movably mounted on a first guide located on the strut, whereby the space between the strut and the rear of the housing is used particularly efficiently and the vehicle headlamp can be constructed particularly compact.
    In order to realize a cost-effectively manufacturable and robust bearing mechanism at the fixed bearing point, it is provided in an advantageous embodiment of the invention that is provided for pivoting about the first and second axis at the fixed bearing point, a two-piece clamping bearing shell.
    According to a fifth variant of the invention, a strut of a headlamp housing extending from an upper side of the housing to a lower side of the housing is provided, wherein the second adjusting means associated with the first adjusting means and translationally movable on the strut is guided, and wherein the second adjusting means with the first
    Adjusting means is fixedly connected. A permanent adjustment of the second actuating means by the first adjusting element is thus particularly easy to influence without affecting the adjustment of the second actuating means.
    It is particularly advantageous if it is provided for pivoting about the second axis, at least on the strut mounted rotary shaft. The rotary shaft may additionally be mounted in the region of the second adjusting bearing point.
    In order to allow a particularly simple production and rapid assembly of the adjustment system according to the invention, the rotary shaft is a component of a frame carrying the optically relevant component, wherein the strut has a rotary shaft receiving, which has an elastic slot-like opening for introducing the rotary shaft, parallel to the second Axis is oriented and the opening size in an unloaded state is less than a diameter of the
    Rotary shaft, and in a loaded state for receiving the rotary shaft is expandable at least up to the rotary shaft diameter. The opening has, for example, to a front of the vehicle headlight.
    It should be noted at this point that all position and direction indications, unless otherwise defined, refer to a vehicle headlamp mounted in a vehicle. The term "front" therefore means that of
    Direction of travel (or the light emission direction) facing side of the headlamp.
    In one embodiment of the invention, it is provided that the frame is made in two parts, wherein the rotary shaft is part of a second frame part, and a first
    Frame part is pivotally mounted about the first axis about the second frame part. In this case, the rotary shaft can be moved particularly close to the center of gravity of the optically relevant component or of the frame, or even pass through it, as a result of which rapid and efficient adjustment of the optically relevant component is possible.
    According to a sixth variant of the invention, the rotary shaft is part of a frame carrying the optically relevant component, wherein the strut has a rotary shaft receptacle with a cylindrical opening, which cylindrical opening for receiving the
    Rotary shaft is set by inserting the rotary shaft in the axial direction of the second axis 6/50 -6- P12564. This structure is particularly robust against external mechanical effects such as Rüttelbelastungen.

    In Fig. 1, a headlamp housing 1 is shown in which a first variant of the adjustment system according to the invention for a vehicle headlamp for adjusting an optically relevant component 2 is arranged. The optically relevant component 2, which in the example shown is a lens, e.g. is a projection lens of a projection module, is held therein in a frame 3, said frame 3 is pivotally mounted about a first and a second axis z and y. The first axis z is aligned vertically, whereby a pivoting movement about the first axis z allows a left-right orientation of the optically relevant component 2. The second axis y is aligned horizontally and extends between a fixed point FP and a second adjusting bearing point P2, wherein a pivoting movement of the optically relevant component 2 about the second axis y makes it possible to regulate the headlamp range of the headlamp, for example dynamic headlamp leveling. A third axis x forms, together with the two axes y and z, a right-handed oriented Cartesian coordinate system, whereby the positive counting direction along the third axis x is opposite to the usual one
    Direction of travel of a vehicle is directed, in which the headlamp is installed. 8/50 -8- P12564 In a protruding end portion of the frame 3, a connecting piece 7 (see Fig. 2) is received, which has a first adjustment bearing point P1. This first adjustment bearing point P1 is set up to cause the pivoting movement about the second axis y, in that it can travel up and down along a circular path around the fixing point FP. The position of the adjusting bearing point P1 is determined on the one hand by the position of the second adjusting bearing point P2 and on the other hand by the position of an actuating element 4, wherein only the position of the actuating element 4 influence the orientation of the optically relevant component 2 with respect to the second Axis has y. The adjusting element 4 is assigned to a second adjusting means 5, this second adjusting means 5 in turn being aligned by a first adjusting means 6 assigned to a second adjusting device V2 (see FIG. 2). The actuating element 4 projects into a first arm section AR 'of an arm AR pivotably mounted about a fourth axis, this fourth axis passing through a third point P3 and oriented in a neutral position parallel to the second axis y. The pivotally mounted arm AR further has a second arm section AR "opposite the first arm section AR '(see FIGS. 2 and 3), which engages with the frame 3 or the connecting piece 7 at its adjusting bearing point P1. The arm AR is preferably L-shaped with the first and second arm portions AR 'and AR "at opposite end portions of the arm AR. The function of the actuating means 5 and 6 is discussed in more detail in the description of FIGS. 2 and 3.
    Fig. 2 shows a perspective view of the adjustment system shown in Fig. 1. The connector 7 is at least partially enclosed within the second arm portion AR "by the arm AR. The adjusting element 4 projects into a receptacle 8 arranged in the first arm section AR ', with the aid of which a translational movement of the adjusting element 4 is converted into a rotational movement of the arm AR about the fourth axis. This rotational movement shifts the position of the first displacement bearing point P1 with respect to the second axis y. After the fourth axis has a spacing with respect to the second axis y, the pivotal path of the second arm portion AR "does not coincide with that of the protruding end portion of the frame 3. In order to prevent a clamping of the connecting piece 7, this is therefore equipped with a certain game, so a certain amount of space for movement. This is e.g. achieved in that the connecting piece 7 at its the second arm portion AR "facing the end has a cylindrical extension which is slotted along its longitudinal axis and whose diameter exceeds the thickness of other regions of the connecting piece 7. After pivoting of the frame 3 about the first axis z of the connecting piece 7 moves together with the frame 3, the connecting piece 7 is made so wide (this essentially relates to the extent in the direction of the second axis y), that even at 9 / 50 -9- P12564 a pivoting operation about the first axis z at least a portion of the connecting piece 7 in the second arm portion AR "protrudes.
    The adjustment system has a first and a second adjustment V1 and V2, wherein the first adjustment V1 acts on the second adjustment bearing point P2, and the second adjustment V2 acts on the first adjustment bearing point P1. Both adjusting devices V1 and V2 are adjustable via rotatable adjusting elements, in particular adjusting screws. Thus, the adjusting elements act in the embodiment shown in each case via a bevel gear on a corresponding shaft having at least at one portion a thread along which a respective thrust element moves in translation depending on the direction of rotation of the shaft. In the case of the first adjusting device V1, this pushing element is in direct engagement with the second adjusting bearing point P2, whereby a pivoting of the optically relevant component 2 about the first axis z is made possible. The thrust element of the second adjusting device V2 represents the first adjusting means 6 and acts on the second adjusting means 5 by the second actuating means 5 is fixedly connected to the first actuating means 6 and thus the relative movement of the first actuating means 6 with respect to the shaft corresponding to the bevel gear follows. The second adjusting means 5 has an electric motor which allows a linear movement of the adjusting element 4. With the help of the electric motor, for example, a dynamic headlamp leveling can be realized. After the setting range of the second setting means 5 determines the possible relative positions of the setting element 4 with respect to the second setting means 5, an absolute adjustment of the second setting means 5 by the first setting means 6 for the setting range of the second setting means 5 is irrelevant. By the second adjusting device V2, therefore, the position of the optically relevant component 2 can be added in a simple manner, a kind of "offset". It is particularly advantageous that in the embodiment shown, the adjustment of the second actuating means 4 and the adjusting element 5 with the adjustment of the first actuating means 6 and the thrust element, ie the thrust direction coincides. The mechanical configuration of the adjusting devices V1 and V2 can deviate from the illustrated variants in any manner known to the person skilled in the art. In general, all components and variants shown by the expert can be modified and not to be considered as limiting.
    The fixed point is formed by a clamping bearing 9 which is held on a strut 10 shown in FIG. 1, wherein the strut 10 extends from a rear side of the housing in the direction of the front of the housing. The clamping bearing 9 has in the embodiment shown on a ball head, which projects into a cup-shaped receptacle of the frame 3, wherein a shaft attached to the ball shaft penetrates the cup-shaped receptacle of the frame 3 10/50 -10- P12564 and projects into the strut 10. The mounted on the ball shaft shaft has a thread, with the help of which allows a simple and secure connection of the ball head with the strut and efficient storage of the frame 3 is ensured.
    FIG. 3 shows a side view of the adjustment system according to FIG. 1 and FIG. 2. Herein, the arrangement of the adjustment means 5 and 6 is particularly clearly visible.
    FIG. 4 shows a second variant of the invention, which differs from the first variant of the invention in the manner described below (the reference numerals are used analogously to the other variants described). The second adjusting means 5 is movably mounted for adjustment by the first adjusting means 6 on a first guide 11 located on the rear side of the housing. This guide 11 is in the embodiment shown as well as the adjustment direction of the first and the second actuating means 5 and 6 vertically aligned. These components do not necessarily have to be aligned vertically. It is essential that the direction of movement of the second actuating means 5 and the actuating element 4 has a sufficient normal component to that of a connecting path of fixed bearing point FP and the first adjustment bearing point P1 to the frame 3 carrying the optically relevant component 2 for alignment be able to apply the same sufficient torque. In contrast to the first variant, the adjusting element 4 engages with a transmission element UE movably guided on a second guide 12 (visible in FIG. 5), wherein the second guide 12 is fixedly connected to the second actuating means 5, wherein the optically relevant component 2 is received in a frame 3, and the optically relevant component 2 is pivotable together with the frame 3 about the first and the second axis z and y. The connection of the transmission element UE (which has a first and a second opening region UE 'and UE "shown in FIG. 7) to the frame 3 is analogous to the connection of the arm AR to the frame 3 in the first variant. This means that the frame 3 as well as in variant one has a protruding end portion with a connection piece 7 received therein, at which the adjusting bearing point P1 comes to rest. The connecting piece 7 is enclosed at least partially within a second opening area UE "by the transmission element UE. In order to prevent a clamping of the connecting piece 7, this is therefore equipped with a certain game, so a certain amount of space for movement. This is e.g. achieved in that the connecting piece 7 at its second opening region UE "end facing a cylindrical extension which is slotted along its longitudinal axis and whose diameter exceeds the thickness of other regions of the connecting piece 7. After the first axis z of the connecting piece 7 moves together with the frame 3 when the frame 3 is pivoted about 11/50 - 11 - P12564, the connecting piece 7 is made so wide (this essentially relates to the extension in the direction of the second axis y ) that even at a pivoting about the first axis z at least a portion of the connecting piece 7 in the second opening area UE "protrudes.
    Fig. 5 shows the adjustment system of FIG. 4 in a perspective view. Therein, the second guide 12 and the transmission element UE accommodated therein are easily recognizable.
    6 shows a sectional view of the first and the second guide 11 and 12 of the adjusting system according to FIG. 4. The first adjusting means 6 has two opposite holding regions, which enclose the first guide 11 and clamp the first adjusting means 6 to the first guide 11. The second guide 12 is arranged on the first adjusting means 6 (which is fixedly connected to the second adjusting means 5), wherein the transmission element UE has holding regions which enclose the second guide 12 and clamp the transmission element UE to the first actuating means 6.
    FIG. 7 shows the adjustment system according to FIG. 4 and FIG. 5 in a side view, wherein in particular the mode of operation of the second adjustment device V2 can be seen. The adjusting V2 is adjustable via a rotatable adjusting element, in particular an adjusting screw. In contrast to the first variant, the adjusting element of the second adjusting device V2 acts in the embodiment shown via a spur gear on a corresponding shaft having at least at one portion a thread along which a respective thrust element moves in translation depending on the direction of rotation of the shaft. The thrust element of the second adjusting device V2 represents the first adjusting means 6 and acts on the second adjusting means 5 by the second actuating means 5 is fixedly connected to the first actuating means 6 and thus the relative movement of the first actuating means 6 with respect to the shaft corresponding to the spur gear follows. The transmission element UE and the first guide 11 are recognizable by sectional views. Thus, the first opening area UE 'of the transmission element UE is clearly visible, in which the actuator 4 projects and a spherical end portion of the control element 4 is clamped. An adjusting movement taking place by the adjusting element 4 can thus be transmitted efficiently via the transmission element UE to the connecting piece 7 and thus to the frame 3. For the remaining features, what has been said in the first variant applies. 12/50 -12- P12564
    Fig. 8 shows a headlamp housing with an adjustment system according to the invention in a third variant. This differs from the second variant, by the structure of the strut 10 and the arrangement of the second adjusting V2 and the first and second guide 11 and 12, the first actuating means 6, the second actuating means 5, the actuating element 4 and the associated transmission element UE , Thus, the strut 10 preferably extends vertically from a housing top to a housing bottom of a headlight housing, wherein the fixed bearing point FP in an analogous manner to the
    Variants one and two arranged on the strut and preferably realized by a clamping bearing 9. By dispensing with a connection of the strut 10 with the
    Case back, the space between the back of the case and the strut 10 can be used, whereby the adjustment system can be made very compact. Thus, the arrangement of the second adjusting device V2 and the first and second guide 11 and 12, the first actuating means 5, the second actuating means 6, the actuating element 4 and the associated transmission element UE in contrast to the second variant of
    Invention at least partially behind the strut 10, so moved into the area between the back of the case and strut 10.
    9 shows a perspective view of this third variant of the invention, in which, for example, the second guide 12 is designed and recognizable analogously to the second variant. Furthermore, FIG. 10 shows a side view in which the mode of operation of the transmission element UE is illustrated analogously to the second variant. in the
    Contrary to the second variant, the second opening area UE "extends along the entire dimension of the transmission element UE along a movement path of the connecting piece 7.
    A fourth variant of the invention is shown in FIG. 11. Analogous to the variants one to three, an optically relevant component 2 is held therein in a frame 3 which has a protruding end region. The frame 3 is together with the optically relevant component 2 about a first and a second axis z and y (see the introduction
    Definition of the axes) pivotally mounted. For this are a first and a second
    Adjustment bearing point P1 and P2 and a fixed bearing point FP provided, wherein the fixed bearing point FP is arranged in a manner analogous to the variants one to three on a strut 10 and preferably realized as a clamping bearing 9, wherein the strut 10 preferably vertically from a housing top extends to a housing bottom of a headlight housing. By dispensing with a connection of the strut 10 with the rear side of the case, the space between the rear side of the housing and the strut 10 can be used, whereby the adjustment system can be made very compact. 13/50 -13- P12564
    The adjustment system has a first and a second adjustment V1 and V2, wherein the first adjustment V1 acts on the second adjustment bearing point P2, and the second adjustment V2 acts on the first adjustment bearing point P1. Both adjusting devices V1 and V2 are adjustable via rotatable adjusting elements, in particular adjusting screws. Thus, in the embodiment shown, the adjusting element of the first adjusting device V1 acts via a bevel gear on a corresponding shaft which has a thread at least at one section, along which a respective thrust element translates depending on the direction of rotation of the shaft. In the first adjusting device V1, this pushing element is in direct engagement with the second adjusting bearing point P2, whereby a pivoting of the optically relevant component 2 about the first axis z is made possible. In the second adjusting device V2, the rotation of the adjusting element is transmitted via a spur gear to a corresponding shaft having at least at one portion a thread along which a respective thrust element moves in translation depending on the direction of rotation of the shaft. This thrust element is the first adjusting means 6, which first adjusting means 6 is guided and held on a first guide 11 arranged on the strut 10 (see FIG. 13). The first adjusting means 6 engages in an opening area HA 'of a holding arm HA, wherein the holding arm HA has a first end portion HA "(see FIG. 14), which is articulated to a suspension element 13 fixedly connected to the strut 10. The holding arm HA further has a holding section HA "(see FIG. 14), in which the second setting means 5 is held, in particular fixedly connected to the holding arm HA. The second adjusting means 5 has analogous to the variants one to three (and the other variants shown) via an electric motor which allows a linear movement of the adjusting element 4, wherein the adjusting element 4 with a protruding end portion of the frame 3 at the first adjusting bearing point P1 in Intervention is. A linear movement of the actuating element 4 leads to a pivoting of the frame 3 and thus of the optically relevant component 2 about the second axis y. During a pivoting movement of the frame 3 about the first axis z, the protruding end region together with the second adjusting means 5 and the adjusting element 4 associated therewith migrates along a pivoting path about the articulated connection with the suspension element 13. The embodiment of this connection is shown in FIG Detail shown. The fixed bearing point FP is arranged analogously to the variants one to three on the strut 10 and preferably realized as a clamping bearing 9. Since the first guide 11 is fixedly mounted on the strut 10 or integral therewith, the second actuating means 5 arranged within the holding section HA '"of the holding arm HA has a defined free movement space in the pivoting direction (with respect to the first actuating means 6) the first axis z or to the articulated connection with the suspension element 13, so that the support arm HA can follow the pivoting movement of the protruding end portion of the frame 3. The first adjusting means 6 has in the embodiment variant shown in FIG. 14/50 - 14 - P12564 a bolt, which is displaceable into a slot-shaped opening track forming the holding section HA '"into a latching position, wherein the
    Bolt displaceable in the latching position along the above-described pivot path and is positively held in the direction of the first axis z. The connection of the projecting end region with the rest of the frame 3 has for this purpose a recess 14 which prevents a collision limiting the pivoting movement with the second adjusting device V2 (see in particular Fig. 14).
    This construction can be seen in FIG. 12 in a perspective view, in which additionally the first adjusting device V1 is indicated. Fig. 13 shows a side view of the fourth variant, wherein therein the first guide 11 is clearly visible, which preferably extends in the direction of the first axis z.
    FIG. 14 shows the fourth variant according to FIGS. 11 to 13 in a perspective sectional representation. The first end portion HA "of the support arm HA is spherically formed therein and articulated in a cup-like socket of the suspension member. The fixed bearing point FP is realized as a clamping bearing 9, wherein a screw with a spherical head is screwed to the strut 10, which spherical head is pivotally received in a shell-like counterpart of the frame 3. The adjusting element 4 protrudes into the protruding end region of the frame 3 and is adapted to transmit the linear movement of the adjusting element 4 to the frame 3. The connection of the adjusting element 4 with the protruding end portion of the frame 3 can also be given by a spherical extension of the adjusting element 4, which projects into a pan enclosing the ball of the protruding end portion of the frame 3.
    By dispensing with a guide arranged on the rear side of the housing, the adjustment system can be preassembled in a simple manner and quickly inserted into the headlight housing. The materials used for the adjustment system can be chosen more freely in this case, as is dispensed with guides on the headlight housing, which headlight housing is usually made of hard and brittle material. This results in an improved material pairing.
    FIG. 15 shows a headlight housing in which a fifth variant of the adjustment system according to the invention is accommodated. The frame 3 is constructed in two parts and consists of a first and a second frame part 3 'and 3 ", wherein the first frame part 3' carries the optically relevant component 2 and together with this about a first 15/50 -15- P12564 and a second axis z and y (see at the beginning carried out definition of the axes) is pivotally mounted. For this purpose, a first and a second Verstelllagerpunkt P1 and P2 and a fixed bearing point FP are provided, the fixed bearing point FP, in contrast to the variants one to four, although arranged on a strut 10 but by a rotary shaft 15 and a preferably normal oriented Joint assembly 16 is formed. The strut 10 preferably extends vertically from a housing top to a housing bottom of the headlight housing. By dispensing with a connection of the strut 10 with the rear side of the case, the space between the rear side of the housing and the strut 10 can be used, whereby the adjustment system can be made very compact.
    The adjustment system has a first and a second adjustment V1 and V2, wherein the first adjustment V1 acts on the second adjustment bearing point P2, and the second adjustment V2 acts on the first adjustment bearing point P1. Both adjusting devices V1 and V2 are adjustable via rotatable adjusting elements, in particular adjusting screws. Thus, in the embodiment shown, the adjusting element of the first adjusting device V1 acts via a bevel gear (see FIG. 17 or analogous to FIG. 21) on a corresponding shaft which has a thread at least at one section, along which a respective thrust element depends the direction of rotation of the shaft translationally (preferably only parallel to the third axis x, this applies to all mentioned variants of the invention) moves. In the first adjusting device V1, this pushing element is in direct engagement with the second adjusting bearing point P2, whereby a pivoting of the optically relevant component 2 about the first axis z is made possible.
    In the second adjusting device V2, the rotation of the adjusting element is transmitted via a spur gear to a corresponding shaft, which at least at one portion has a thread along which a respective thrust element depending on the direction of rotation translationally moves (preferably only parallel to the first axis z). This thrust element represents the first adjusting means 6, which first adjusting means 6 is guided and held on a first guide 11 arranged on the strut 10, as can be seen in particular in FIG. 17.
    The second adjusting means 5 is fixedly connected to the first adjusting means 6 by the second adjusting means 5 is screwed for example with a holding portion of the first actuating means 6 or clamped in this. The second adjusting means 5 has an electric motor which allows a linear movement of the adjusting element 4. After the setting range of the second setting means 5 determines the possible relative positions of the setting element 4 with respect to the second setting means 5, an absolute adjustment of the second setting means 5 by the first 16/50 16 P12564
    Adjustment means 6 for the adjustment range of the second actuating means 5 without meaning. By the second adjusting device V2, therefore, the position of the optically relevant component 2 can be added in a simple manner, a kind of "offset". It is particularly advantageous that in the embodiment shown, the adjustment of the second actuating means 4 and the adjusting element 4 with the adjustment of the first actuating means 6 and the thrust element, ie the thrust direction coincides.
    The adjusting element 4 engages with a protruding end portion of the frame 3, which is arranged on the second frame part 3 ", at the first adjusting bearing point P1. A linear movement of the actuating element 4 leads to a pivoting of the entire frame 3 and thus of the optically relevant component 2 about the second axis y. In this case, the frame 3 rotates consisting of the two frame parts 3 'and 3 "together with the rotary shaft 15 which is fixedly connected to the second frame part 3", in particular in one piece and is held in a arranged on the strut 10 rotary shaft receptacle 17. The rotary shaft receptacle 17 is designed shell-like, wherein in the embodiment shown two spaced apart in the direction of the second axis y shells are formed substantially analogous to lateral surfaces of a cylinder, said shells have a in the direction of the second axis y extending slot-like opening 18, the the lying in the direction of travel (ie opposite to the positive counting direction of the third axis x) side of the shells. This slot-like opening 18 is embodied in such a way that the rotary shaft 15 can be pressed into the rotary shaft receiver 17 under the action of force from the front, that is to say counter to the direction of travel (see in particular FIGS. 18 and 19). The shells are designed, for example, elastic, so that the slot-like opening 18 expands under the onset of the rotary shaft 15 occurring mechanical stress (corresponding to a loading condition) up to the rotary shaft diameter. The rotary shaft 15 can thus in the
    Rotate rotary shaft holder 17. Once the rotary shaft 15 completely in the
    Rotary shaft receptacle 17 is added, the dimension slit-like opening 18 is reduced back to an unloaded state in which the diameter of the rotary shaft 15 is greater than a necessary opening size for rotary shaft removal of the slot-like opening 18. The second frame part 3 "can thus be particularly easy on the Strut 10 are mounted by the rotary shaft 15 is simply pressed into the rotary shaft receptacle 17, whereby a simple and inexpensive storage of the second frame part 3 "is realized.
    The first frame part 3 'is connected to the second frame part 3 "via a hinge arrangement 16. The hinge assembly 16 consists in the embodiment shown of two spaced apart arms with cylindrical rotary shaft-like end portions, which are in corresponding, on the second frame part 3 "receptacles are used, the recordings the cylindrical rotary shaft-like end portions at least partially enclose, hold them in their position, while allowing a rotation of the first frame part 3 'about the first axis z. For this purpose, the cylindrical rotary shaft-like end portions are aligned coaxially, with their axes coincide with the first axis z. As can be seen in particular in FIG. 19, a ring accommodated in the first frame part 3 'is arranged between the cylindrical rotary shaft-like end sections, which engages in the rotary shaft receptacle 17 and additionally stabilizes the first frame part 3' in the direction of the second axis y.
    In general, any joint arrangements 16 are conceivable which enable pivoting of the first frame part 3 'about a first axis z and about the second frame part 3 ".
    In the embodiment shown, the common center of gravity of the frame 3 and the optically relevant component 2 lies on the second axis y, so that the force or torque required to carry out a pivotal movement is minimal and the vibration resistance of the adjustment system increases. Alternatively, however, the center of gravity may also deviate from the second axis y, depending on the nature of the optically relevant component 2. By dispensing with a guide arranged on the rear side of the housing, the adjustment system can be preassembled in a simple manner and quickly inserted into the headlight housing. The materials used for the adjustment system can be chosen more freely in this case, as is dispensed with guides on the headlight housing, which headlight housing is usually made of hard and brittle material. This results in an improved material pairing.
    Fig. 20 shows a sixth variant of the invention, which differs from the fifth variant by the features described below. The rotary shaft receptacle 17 has in contrast to the variant five no expandable slot-like opening 18. The insertion of the rotary shaft 15 takes place here by insertion into the rotary shaft receptacle 17 in the direction of the second axis y. The rotary shaft receptacle 17 in this case has a cylindrical opening 19, which is oriented analogously to a top surface of a cylinder whose axis is aligned parallel to the second axis y. Consequently, the rotational shaft 15 arranged on the second frame part 3 "can not be moved or removed in the direction of the third axis x, with which this sixth variant of the invention withstands particularly high vibratory loads. In order to counteract a slipping out of the rotary shaft 15 from the rotary shaft receptacle 17 in the direction of the second axis y, a holding opening 20 is provided in the second frame part 3 ", which holding opening 20 is adapted to a corresponding holding element 21 arranged on the strut 10. 50 -18- P12564 record. For this purpose, holding opening 20 is circular, wherein the circular holding opening 20 is widened in a slot-like manner in a holding area. The holding element 21 has a holding head in an end region, which holding head faces into the holding opening 20 of the holding opening 20 before the insertion process, and whose diameter exceeds that of the remaining holding element 21. The diameter of the holding head is smaller than that circular diameter of the holding opening 20, so that the holding head can be brought through the holding opening 20. A fixing of the second frame part 3 "in the direction of the second axis y is achieved by the holding element 21 is moved into the slot-like extension after insertion of the holding head into the holding opening 20, wherein the diameter of the holding head exceeds that of the slot-like extension. The slot-like extension is aligned so that a pivoting movement of the second frame part 3 "and thus the holding opening 20 about the second axis y is not hindered.
    In other words, the arrangement of the components (first frame part 3 'and adjusting device V2) transmits the main load via the strut 10 to a housing holding the strut 10. The retaining element 21 serves only to secure the second frame part 3 "against slipping out and is exposed to negligible loads.
    In general, any arrangements known to the person skilled in the art are suitable which do not hinder the pivoting movement of the second frame part 3 "and allow a fixation in the direction of the second axis y. 19/50 P12564
