    VEHICLE HEADLIGHTS WITH A STELLB AREN CONSTRUCTION UNITS
    The invention relates to a vehicle headlamp with a housing and at least two optically relevant units, each optically relevant assembly is mounted in a separate support member and each support member is mounted relative to the housing in each case about a horizontal axis and pivotable about a vertical axis, wherein for pivoting the support elements are provided with a horizontal axis pivoting device about their horizontal axes, which horizontal axis pivoting device is movably connected by means of a horizontal axis coupling device with at least two support elements pivotable about their horizontal axes, and wherein a vertical axis pivoting device is provided for pivoting the support elements about their vertical axes, which vertical axis pivoting device, if necessary, by means of a about a coupling device vertical axis with respect to the housing rotatably mounted vertical axis coupling device with the Indirectly two pivotable about their vertical axes support elements is coupled.
    In the context of the present application, an optically relevant structural unit is understood as meaning, for example, a single light module or a light module unit with a plurality of light modules. Typically, a light module unit is an assembly of multiple light modules that can be adjusted together by, for example, rigidly mounting or otherwise connecting the unitary light modules to a common support. With a light module, a specific light distribution, such as a high beam distribution, a dimmed light distribution such as a dipped beam, or a fog light distribution can be generated, or a light module contributes as a component in the context of a light module unit for generating such a light distribution.
    In a previously mentioned optically relevant component of a light module or a light module unit, which has an influence on the light distribution generated with the light module or with the light module unit, it may be, for example, a reflector, a lens, a diaphragm, a light source or a light source arrangement or other light-shaping means, such as optical fibers and / or light guide body act.
    As is known, it is necessary or legally required for vehicle headlights that the light pencil produced by the headlight can be adjusted in the vertical and / or horizontal direction in accordance with a predetermined basic setting. If the vehicle headlight comprises one or more light modules or light module units, then it is usually provided that these light modules or relevant components of these light modules, which influence the alignment or adjustment of the emitted light bundle, such as lenses or reflectors, also according to the legal Specifications or the corresponding customer specifications can be set. Usually, the adjustment of the light modules, the light module units or their components by pivoting about axes, typically around horizontal and / or vertical axes. Furthermore, for the sake of simplicity, only a setting of light modules is mentioned. In the context of the application, however, it should be understood that this means that only individual components of such light modules can be meant.
    If the vehicle headlight comprises two or more light modules, then it is generally favorable if these light modules are fastened on a common support frame, which common support frame can be pivoted with corresponding adjustment devices about a horizontal and / or about a vertical axis. In this way, two or more light modules can be adjusted in one direction with a single adjustment, or can be set with two adjusters the light modules in the vertical and in the horizontal direction.
    Vehicle headlights in which a plurality of light modules can be pivoted about vertical axes are already known, for example, from US 2008/0247182 A1, WO 2013/032637 A1 and DE 102 38 792 A1.
    However, certain designs of modern vehicle design may increasingly require an arrangement of the light modules with a "sweep" within the vehicle headlamp.The term sweep is understood to mean that usually the one or more outer light modules of a headlamp compared to the respective The angle between a vertical plane, which passes through two light modules of a headlamp, and a vertical plane normal to the direction of travel is referred to as the sweep angle in today's vehicles are already sweep angles of the light modules to each other realized by about 45 °.
    However, as the sweep angle increases, it becomes more difficult or even impossible to place two or more light modules - for example, a low beam and a high beam light module - on a common support frame because of the large sweep and long distance from the pivot point of the support frame very large deflections would come when pivoting the light modules. For such headlight geometries, it is therefore necessary to make each light module or each light module unit separately adjustable, for example by arranging each light module on a separate support frame, which support frame is pivotable about a horizontal and / or about a vertical axis. Accordingly, a separate adjusting device is required for each light module and for each pivot axis, which is expensive both in production and in maintenance.
    From document AT 514402 A1, a vehicle headlamp is already known, in which a plurality of optically relevant structural units, such as light modules or light module units, can be set together with only one adjustment device per adjustment direction. The light module units are offset below a sweep angle next to each other in a common horizontal headlamp level and mounted together pivotable about a vertical axis of rotation. A disadvantage of this design, however, is the high space requirement of the vehicle headlamp especially for complex lighting tasks, so if several light module units are required side by side. Furthermore, due to the large distances between the individual light module units due to the sweep angle, the lever arms required for the common adjustment of the light module units are large, which is why a large deflection of the pivoted light modules inevitably occurs during the adjustment. The disadvantage of these long lever arms of the pivoting mechanism for vibrations during driving to an undesirably high force in the support frame of the light modules.
    It is therefore an object of the invention to provide a vehicle headlight, in which the disadvantages known from the prior art are overcome and in which a plurality of light module units are arranged particularly compact such that the deflections of the pivoted light modules reduced and the force on the pivoting mechanism is lowered when shaken.
    This object is achieved with a vehicle headlamp mentioned above in that according to the invention the support elements are arranged at least in two vertically spaced headlight planes, the horizontal axis coupling device with at least two support elements movably connected and rotatably mounted about a coupling device horizontal axis with respect to the housing is.
    In the context of the present application, the term "headlamp level" is understood to mean a substantially horizontal plane which is defined on a substantially horizontal contour line of an optically relevant structural unit or on a substantially horizontal contour line of a support element. In a vehicle headlight according to the invention, the light module units are arranged at least in two different headlight planes, which are spaced apart from one another in the vertical direction. The light module units can be arranged vertically offset one above the other and / or laterally offset from each other in two or more vertically spaced headlight planes. In particular, for those embodiments in which two, three or even more carrying elements together with the associated light module units are arranged in a matrix-like manner and offset laterally relative to each other, the invention overcomes the aforementioned disadvantages of light modules arranged with a sweep within a vehicle headlight. Since a plurality of light modules arranged side by side in a spotlight plane with a sweep also reaches a maximum quickly - for example, three or four juxtaposed light module units may already be too wide to accommodate them together in a vehicle headlight - advantageously in a vehicle headlamp according to the invention Light modules in several headlight levels arranged one above the other.
    Advantageously, in a vehicle headlight according to the invention, a plurality of optically relevant structural units, for example a plurality of light module units, can be arranged particularly compactly in two or more headlight planes spaced apart from one another in the vertical direction. Due to the compact arrangement of the units one above the other, the deflection movements of the pivoted light modules are reduced and also the force acting on the pivoting mechanism in case of shocks is reduced by the shorter distances of the coupling devices to the individual optically relevant units.
    In a further advantageous embodiment of the invention, in a vehicle headlight, the horizontal axis coupling device with at least two support elements, which are arranged in at least two mutually vertically spaced headlight planes, be connected directly movable. In this variant of the invention, the horizontal axis coupling device is used for the direct connection of arranged in at least two superposed headlight planes support elements. Thus, the light modules mounted in the support elements, regardless of their arrangement in the different headlamp levels of one and the same
    Horizontal axis coupling device are regulated together in their headlight range setting.
    It may further be advantageous in a vehicle headlamp according to the invention if the horizontal axis coupling device is connected to at least two support members directly movable and is indirectly connected to at least one further support member by means of a coupling element. In this variant of the invention, for example, in two or more headlight planes directly superimposed support members with the horizontal axis coupling device can be directly connected to each other and supporting elements, which are laterally offset in a sweep angle arranged in one or more headlight planes are with one or more Coupling elements indirectly connected to the horizontal axis coupling device.
    In a further expedient embodiment, at least three optically relevant structural units can be provided in a vehicle headlight according to the invention, wherein at least two optically relevant structural units are arranged with their support elements side by side in a first headlight plane and at least one further optically relevant structural unit with its support element in a vertical direction of the first headlamp level spaced further headlamp level is arranged. In this embodiment, at least three optically relevant modules are arranged in a matrix-like manner in a plurality of vertically spaced-apart headlight planes.
    Suitably, in a vehicle headlight according to the invention, each support element can be mounted in the housing with three bearing points, with a first horizontal bearing point and a second fix bearing point each forming bearings about the respective horizontal axis and the second fixed bearing point and a third vertical bearing point respectively Form bearings around the respective vertical axis of the support elements. Advantageously, the three bearing points of each support element form a stable bearing triangle, wherein in each case two of the three bearing points form the bearings about the horizontal or vertical axis. The bearing triangle is also referred to as an adjustment triangle.
    Particularly advantageously, in a vehicle headlamp according to the invention, the second fixed bearing point of each support element can be stationary relative to the housing in each case. In this embodiment of the invention, the fixed bearing point serves as a stationary bearing with respect to the housing, whereby the position of the support element is fixed in relation to the housing. About the fixed bearing point, through which extend both the horizontal axis and the vertical axis of the respective support member and intersect there, the support member is articulated to the housing or on a fixed in relation to the housing component, such as a base plate, articulated. The fixed bearing point is thus not displaceable with respect to the housing, but pivoting movements of the support element about this fixed bearing point in the horizontal as well as in the vertical direction are possible.
    In a preferred embodiment of the invention, in the case of a vehicle headlight, the horizontal axis pivoting device can engage, preferably directly engage, the horizontal axis coupling device. In this embodiment, the horizontal axis pivoting device and the horizontal axis coupling device are preferably coupled directly to each other.
    Advantageously, in a further embodiment variant of the invention in a vehicle headlight, the vertical axis pivoting device can act on the vertical axis coupling device, preferably attacking it directly. In this embodiment, the vertical axis pivoting device and the vertical axis coupling device are preferably coupled directly to one another.
    It may be particularly useful when in a vehicle headlamp according to the invention about a coupling device vertical axis rotatably mounted vertical axis coupling device to alien pivotable support elements, preferably directly engages.
    Advantageously, in a vehicle headlamp according to the invention, the vertical axis coupling device connects the support elements directly to one another. In a further advantageous embodiment, the vertical axis coupling device is preferably articulated in a vehicle headlamp with the pivotable support elements in their horizontal bearing points.
    In a particularly compact embodiment of the invention, the horizontal axis coupling device connects at least two support frames directly to each other.
    In a further advantageous variant of the invention, in a vehicle headlight, the horizontal axis coupling device is connected to all supporting elements directly and / or indirectly movably.
    In a vehicle headlight according to the invention, the horizontal axis coupling device is expediently connected in an articulated manner to the pivotable support elements in each case in their vertical bearing points.
    A particularly compact vehicle headlight according to the invention is when the coupling device horizontal axis is arranged between two headlight planes which are spaced apart from one another in the vertical direction. In this embodiment of the invention, the coupling device horizontal axis is arranged in the vertical direction between two spaced apart headlight planes and thus between two support elements arranged one behind the other. The storage of the horizontal axis coupling device to this coupling device horizontal axis thus allows short distances to the interconnected support elements, which also reduces the deflections of the pivoted light modules and the force is reduced to the pivoting mechanism of the headlamp leveling in case of shocks.
    Advantageously, in a vehicle headlamp according to the invention, the coupling device horizontal axis is arranged substantially centrally of the horizontal axis coupling device. In this particularly compact design is the storage of the horizontal axis coupling device to the coupling horizontal axis, which forms the horizontal axis of rotation of the horizontal axis coupling device, approximately centrally between the vertically spaced headlight planes and the support elements located there, whereby the deflections of the pivoted light modules further reduced and the force on the pivoting mechanism in case of shocks are further reduced.
    In a further advantageous embodiment variant of the invention, in a vehicle headlight, the coupling device vertical axis is arranged substantially centrally of the vertical axis coupling device. The coupling device vertical axis forms the vertical axis of rotation of the vertical axis coupling device. By arranging them substantially in the center of the vertical axis coupling device, the deflections of the pivoted light modules can be reduced and the force acting on the pivoting mechanism of the luminaire horizontal adjustment can be reduced in case of shocks.
    Particularly useful in a vehicle headlamp according to the invention with the horizontal axis coupling device all support elements are each synchronously pivotable about their horizontal axes. Advantageously, in this embodiment, all supporting elements, regardless of their arrangement in the multiple headlamp planes with the horizontal axis coupling device simultaneously and synchronously pivoted about their horizontal axes.
    It is advantageous in a vehicle headlamp according to the invention that with the vertical axis coupling device all supporting elements are each synchronously pivotable about their vertical axes. Advantageously, in this embodiment, all supporting elements, regardless of their arrangement in the plurality of headlamp planes with the vertical axis coupling device simultaneously and synchronously pivoted about their vertical axes.
    In a further development of the invention, the horizontal axis coupling device and / or the vertical axis coupling device are or are formed as einstiickiges coupling element in a vehicle headlight.
    In addition, in the context of the invention, a vehicle is specified which comprises at least one vehicle headlamp according to the invention.
    Further details, features and advantages of the invention will become apparent from the following explanation of exemplary embodiments schematically illustrated in the drawings. 1 shows an isometric view obliquely from the front of a first embodiment of an opened vehicle headlight according to the invention; FIGS. 2 and 3 are each a plan view of the embodiment illustrated in FIG
    Vehicle headlight; FIGS. 4 and 5 each show a side view of that illustrated in FIG. 1
    Execution of a vehicle headlight; and FIG. 6 is a frontal view from the front of a second embodiment of a vehicle headlight according to the invention within a headlight housing.
    Figures 1 to 5 each show a section of a vehicle headlight 1, which has a housing 10 which is illustrated by a base plate 20 as part of the housing 10 and three support elements 100, 200, 300 has, each for receiving or for Holder of optically relevant units serve 110,210,310. The position of the optically relevant units 110, 210, 310 within the
    Support members 100, 200, 300 is indicated in Fig. 1 respectively by dashed rectangles.
    As already mentioned, an optically relevant assembly 110, 210, 310 is, for example, a light module, a light module unit, which consists of one or more light modules, or one or more components of such
    Light module or such a light module unit, these components have an influence on the light generated with the light module or with the light module unit light distribution.
    Each support element 100, 200, 300 is in each case designed to pivot about its horizontal axis Hi, H2, H3 as well as about its vertical axis Vi, V2, V3 and in each case as a support frame. Thus, the units 110, 210, 310 fixed in the support elements 100, 200, 300 can be pivoted in the horizontal as well as in the vertical axis direction, respectively. To set a so-called basic setting, the support elements 100, 200, 300 can each be pivoted about the vertical axes Vi, V2, V3, wherein the light image generated by the units 110, 210, 310 is adjusted horizontally. Furthermore, the units 110, 210, 310 can each be pivoted about horizontal axes Hi, H2, H3 for headlight range control. Because of the pivotable support elements 100, 200, 300, these can also be used, for example, for realizing a cornering light function, for which purpose the curved light axes can also be positioned differently from the vertical axes V 1, V 2, V 3.
    In principle, in the context of the invention, the support elements can each also be formed or connected in one piece with the light module or with a light module unit.
    The first support element 100 is mounted with three bearing points 101,102,103 in the housing 10 and on the base plate 20 of the housing, wherein a first and a second bearing point 101, 102, the horizontal axis Hi and the second and a third bearing point 102, 103 form the vertical axis Vi , The second bearing point 102 of the first support element 100 is a fixed bearing point 102, which is stationary with respect to the housing 10. Via the fixed bearing point 102, through which the horizontal axis Hi and the vertical axis Vi run and intersect there, the first support element 100 is articulated to the housing 10 or to a fixed component with respect to the housing 10, namely the base plate 20, articulated. The fixed bearing point 102 is thus not displaceable with respect to the housing 10, but pivoting movements of the support element 100 about this fixed bearing point 102 are possible. The bearing points 101, 102, 103 are essentially arranged in triangular form and form a so-called adjustment triangle of the first support element 100 for the first optically relevant structural unit 110. The first support element 100 is designed here in frame form.
    In addition, the second support element 200 is mounted with three bearing points 201, 202, 203 in the housing 10, wherein a first and a second bearing point 201, 202, the horizontal axis H2 and the second and a third bearing point 202, 203 form the vertical axis V2. The second bearing point 202 of the second support element 200 is a fixed bearing point 202, which is stationary with respect to the housing 10. Via the fixed bearing point 202, through which the horizontal axis H2 and the vertical axis V2 extend and intersect there, the second support element 200 is also articulated to the housing 10 or to a component fixed in relation to the housing. The fixed bearing point 202 is thus not displaceable with respect to the housing 10, but pivoting movements of the second support element 200 about this fixed bearing point 202 are possible.
    The same applies to the third support element 300, which is mounted in the housing 10 with three bearing points 301, 302, 303. A first and a second bearing point 301, 302 form the horizontal axis H3, and the second and a third bearing point 302, 303 form the vertical axis V3. The second bearing point 302 of the third support element 300 is a fixed bearing point 302, which is fixed with respect to the housing 10. Via the fixed bearing point 302, through which the horizontal axis H3 and the vertical axis V3 run and intersect, the third support element 300 is articulated to the housing 10 or articulated to a fixed component with respect to the housing. The fixed bearing point 302 is thus not displaceable with respect to the housing 10, but pivotal movements about this fixed bearing point 302 are also possible for the third support element 300.
    The first support element 100 is designed like a frame for receiving or holding the first optically relevant assembly 110, wherein a substantially horizontal contour line of the optically relevant assembly 110 or a substantially horizontal contour line of the support member 100 in a first headlight plane Ei, which is substantially horizontal is, lie. The first headlight plane Ei is located at a first vertical distance Drv above a likewise substantially horizontal reference plane of the housing 10, for example the reference plane through the base plate 20 of the housing 10, away from the latter.
    The second support element 200 is likewise designed in the manner of a frame for receiving or holding the second optically relevant structural unit 210, wherein a substantially horizontal contour line of the optically relevant structural unit 210 or a substantially horizontal contour line of the support element 200 in a second headlight plane E2, essentially is horizontal, lie. The second headlight plane E2 is located at a second vertical distance D2V above the reference plane through the base plate 20 of the housing 10 away from the latter.
    The third support element 300 is likewise designed in the manner of a frame for receiving or holding the third optically relevant unit 310, wherein a substantially horizontal contour line of the optically relevant unit 310 or a substantially horizontal contour line of the support element 300 in a third headlight plane E3, which is substantially is horizontal, lie. The third headlight plane E3 is located at a third vertical distance D3V below the reference plane through the base plate 20 of the housing 10 from this. Furthermore, the third support element 300 is arranged substantially below the second support element 200, while the first support element 100 - as shown in Fig. 1 - each offset sideways of the other two support members 200, 300 is arranged.
    In the vehicle headlight 1 according to the invention illustrated in FIGS. 1 to 5, the light module units 110, 210, 310 are arranged in three different headlight planes Ei, E2, E3, which are spaced apart from one another in the vertical direction. The light module units 110, 210, 310 can be arranged one above the other and / or laterally offset from each other.
    For common pivoting of the support elements 100,200,300 about their horizontal axes Hi, H2, H3, a horizontal axis pivoting device 40 is provided, whose operation is clearly visible in particular in the figures Fig. 4 and Fig. 5. The horizontal axis pivoting device 40 is used for headlamp leveling of the light modules 110, 210, 310 and includes a coupling joint 41, which is connected to a horizontal axis coupling device 60 - comparable to a vertical lever arm. The horizontal axis coupling device 60 is for this purpose rotatably mounted in a bearing point 61 about a coupling device horizontal axis Hk with respect to the housing 10.
    Furthermore, the horizontal axis pivoting device 40 comprises an actuating element 42 and an actuator 45, preferably an electric drive 45, which in cooperation allow a displacement of the coupling joint 41 of the horizontal axis pivoting device 40 in the double arrow 400. For the pivoting of the support elements 100,200,300 about their horizontal axes Hi, Ha, H3 thus the actuator 45 of the horizontal axis pivoting device 40 is actuated, the horizontal axis pivoting device 40 by means of the horizontal axis coupling device 60 here with two about their horizontal axes H2, H3 pivotable support elements 200th , 300 is connected directly movable. The further support element 100, which is arranged slightly laterally offset with respect to the two support elements 200, 300, is here indirectly connected to the horizontal axis pivoting device 40 by means of a coupling rod element 63, which is also fastened to the horizontal axis coupling device 60.
    Thus, upon actuation of the horizontal axis pivoting device 40, all the support elements 100, 200, 300 are pivoted simultaneously and / or indirectly simultaneously about their horizontal axes Hi, H2, H3, and thus the headlight ranges of the individual units or
    Light modules 110,210,310 are regulated. The actuator 45, preferably an electric drive for headlamp leveling, is arranged so that it is moved with adjustment of the basic setting of the light module units 110, 210, 310 and then in the operation of the headlamp 1, the headlights of the generated light distributions by pivoting about the horizontal Axes Hi, H2, H3, preferably dynamic, regulated.
    For pivoting the support elements 100, 200, 300 around their vertical axes V 1, V 2, V 3, a vertical axis pivoting device 50 is provided, the mode of operation of which can be taken in particular from FIGS. 2 and 3. Typically, this is a pivoting device which has a similar structure as the horizontal axis pivoting device 40. The vertical axis pivoting device 50 is also attached in the example shown with a coupling joint 51 to a vertical axis coupling device 70, which - comparable to a horizontal Lever - is coupled to the support members 100, 200, 300. The vertical axis coupling device 70 is rotatably mounted for this purpose in a bearing point 71 about a coupling device vertical axis Vk with respect to the housing 10. The vertical axis pivoting device 50 further includes an actuating element 52 and an actuator 55, which is designed here for example as an electric drive 55.
    The pivoting device 50 is coupled by means of the vertical axis coupling device 70 with the each about their vertical axes Vi, V2, V3 pivotable support members 100, 200, 300.
    By interaction of the adjusting element 52 and the actuator 55, a displacement of the coupling joint 51 in the double arrow 500 is made possible upon actuation of the vertical axis pivoting device 50. For pivoting the support elements 100, 200, 300 about the vertical axes Vi, V2, V3 thus the actuator 55 of the vertical axis pivoting device 50 is actuated, wherein the vertical axis pivoting device 50 by means of the vertical axis coupling device 70 here with all their vertical axes Vi, V2 , V3 pivotable support members 100, 200, 300 is connected directly movable.
    Thus, upon actuation of the vertical axis pivoting device 50, all supporting elements 100, 200, 300 are pivoted directly and simultaneously about their vertical axes Vi, V2, V3 and thus the horizontal adjustments of the individual building units or light modules 110, 210, 310 are regulated. The actuator 55 is arranged so that it is shifted in adjustment of the basic setting of the light module units 110, 210, 310 and then in the operation of the headlamp 1, the horizontal adjustments of the generated light distributions by pivoting about the vertical axes Vi, V2, V3, preferably dynamic, regulated.
    All articulated connections are advantageously designed as ball joints, so that a rotation of the movable parts in each case about two axes or in both the horizontal, as well as in the vertical direction, can be realized.
    5 shows an arrangement of the support elements 100, 200, 300, which is swiveled in the horizontal axis direction in comparison with FIG. 4, after actuation of the horizontal axis direction.
    Swiveling device 40 for headlamp leveling. By displacing the coupling joint 41 in the direction of the arrow 400, which coupling joint 41 is connected to the horizontal axis coupling device 60 or to the coupling rod element 63, all supporting elements 100, 200, 300 are each rotated about their horizontal axes Hi, H2, H3 by a swivel angle β pivoted about the horizontal axis. The Verschwenkungsrichtungen of the support members 100,200,300 to the horizontal axes Hi, H2, H3 are each indicated by the arrows 401,402,403.
    Due to the arrangement of the horizontal axis of rotation Hk of the horizontal axis coupling device 60 between the support elements 100, 200, 300, preferably in the geometric center between the headlamp levels of the support elements acts in the case of a load, in particular a shock load against the direction of travel only the resulting differential force on the Horizontal axis coupling device 60. The much larger, occurring from the load total force, however, is introduced into the bearing point 61 of the horizontal axis coupling device 60.
    Fig. 3 shows a comparison with FIG. 2 in the vertical axis direction pivoted arrangement of the support members 100,200,300 after actuation of the vertical axis pivoting device 50 for luminaire horizontal adjustment. By displacing the coupling joint 51 in the direction of the arrow 500, which coupling joint 51 is connected to the vertical axis coupling device 70, all supporting elements 100, 200, 300 are respectively pivoted about their vertical axes Vi, V2, V3 about a pivot angle a about the vertical axis. The Verschwenkungsrichtungen of the support members 100,200,300 to the vertical axes Vi, V2, V3 are indicated in each case by the arrows 501,502, 503.
    Due to the arrangement of the vertical axis of rotation Vk of the vertical axis coupling device 70 between the support elements 100,200,300, preferably in the geometric center between the headlamp levels of the support elements, acts in the case of a load, in particular a shock load against the direction of travel only the resulting differential force on the
    Vertical axis coupling device 70. The significantly larger, occurring from the load total force, however, is introduced into the bearing point 71.
    6 shows a frontal view from the front of a second embodiment of a vehicle headlight 1 according to the invention within a headlight housing 10. Here, too, three optically relevant structural units 110, 210, 310 are fastened in three support elements 100, 200, 300, wherein the two support elements 200, 300 essentially are vertically stacked and the support member 100 is laterally offset from the other two support members 200, 300.
