    1. Field of the Invention
    [001] The present invention relates to a fixing arrangement for fixing a component B to a component A with automatic tolerance compensation between components A and B. Additionally, the present application relates to a pre-assembly method of this fixing arrangement, as well as a method of mounting that fixing arrangement. 2. Background of the Invention
    [002] In the state of the art, different constructions of fixing arrangements for fixing a component to another component with automatic tolerance compensation between those components are known. Such fixing arrangements consist mainly of a basic element fixed to the first component. For this purpose, the basic element is, for example, screwed into the first component, tightened and thus dismountable or not dismountable. With the basic element, an adjustment element can be screwed in by matching the threads. This adjustment element is screwed out of the base element to compensate for tolerances between components that are arranged adjacent to each other in the event that a fixing screw connecting the components is screwed into the base element by means of a additional threads. Such constructions are generally known, for example, described in European patent applications 1,780,424 A1 and 2,003,346 A2.
    [003] In the fixing arrangements mentioned in the prior art, it is recognizable that the basic element is, for example, screwed into the first component or is locked in a respective opening.
    [004] The components of the mentioned fixing arrangements are each produced as a plastic part that requires a large installation space due to construction. In addition, the use of plastics to produce the fixation arrangement may come with disadvantages in relation to the stability, integrity and usability of the fixation arrangement in aggressive chemical media or in a thermally overloaded surrounding medium. It is, therefore, desirable to provide a compact fixing arrangement with smaller installation space or space requirements and high durability in the most different application fields.
    [005] The aforementioned fastening arrangements feature a releasable transport safeguard arranged between the adjustment element and the basic elements, so that the adjustment element and the basic element are connected to each other against twisting during a transport of the adjustment arrangement. fixation. In this way, such a transport safeguard ensures that the adjustment element is not released from the basic element and the fixing arrangement arrives incomplete at its final destination, as a consequence. Such a transport safeguard consists, for example, of an elastic membrane that engages an opposingly arranged recess. In this way, the safeguarding of transport can be done through a handle and is non-executable. In the pre-assembly of known fastening arrangements, however, it is known that despite the transport safeguard, the adjustment element was fixed in the base element so strongly that a release of the adjustment element from the base element was only possible with effort high or not at all. This complicates, however, the installation of the fixing arrangement between the two components and is time consuming, which has a negative influence on an effective installation procedure of the fixing arrangement.
    [006] It is, therefore, an objective of the present invention to provide a fixation arrangement that ensures time savings and reliable installation between the two components. It is an additional object of the present invention to provide a method of pre-assembly and a method for assembling such a fixation arrangement. 3. Summary of the Invention
    [007] The above objective is solved by means of a fixing arrangement according to claim 1, a method of pre-assembling the fixing arrangement according to claim 13, and a method of assembling the fixing arrangement according to claim 14. Preferred embodiments and developments of the present invention result from the dependent claims, the description and the accompanying drawings.
    [008] The fixing arrangement according to the invention for fixing a component B to a component A with automatic tolerance compensation between components A and B comprises the following characteristics: a basic element fixable on component A , in which a fixing screw is threadable on the basic element by means of a first pair of threads, an adjustment element having an external thread, which is threadable on the basic element by means of a second pair of threads, in which a first first and a second anti-twist protection are provided between the base element and the adjustment element by means of which a respective release of the adjustment element from the basic element during transport and a locking of the adjustment element with the element basic is avoided. The aforementioned thread pairings have opposite thread directions with respect to each other.
    [009] The fixing arrangement according to the invention is characterized by its compact construction that requires less installation space compared to the known fixing arrangement. To ensure this compact construction while simultaneously maintaining the necessary stability of the fixing arrangement, preferably, metal is used to produce the fixing arrangement. Corresponding to the functionality of the individual components of the fixing arrangement, it is preferred to use different metals for the individual components.
    [0010] Additionally, the fixation arrangement according to the invention is provided with a first and a second anti-twist protection between the adjustment element and the basic element. The first anti-torsion protection represents a transport safeguard or protection provided by a releasable lock connection between the basic element and the adjustment element. The second anti-torque protection safeguards the fixing arrangement against blockage of the basic element and the adjustment element, meaning that the second anti-torque protection prevents the adjustment element from being screwed into the basic element which is too tight. For this purpose, the second anti-torque protection locks an additional screwing of the adjustment element into the base element at a specific angle position between the adjustment element and the base element. By means of these combined first and second anti-twist protection, the secure and related transport of the fixing arrangement consisting of the basic element and the adjusting element is ensured, as well as an efficient mounting of the fixation arrangement between components A and B The first and second anti-twist protection are carried out in different construction media. According to different preferred embodiments of the invention, which will be explained in detail below, these are carried out in elements that are separated from each other or, usually in just one element.
    [0011] According to a preferred modality, the first anti-twist protection that is also referred to as transport safeguard is an elastic web (web) arranged in the axial direction of the adjustment element through which a connection lockable and rotatable release is created between the adjustment element and the base element. The transport safeguard projects in the radial direction in addition to at least part of the adjustment element so that an elastic movement of the adjustment element in the axial direction is ensured. In a preferred embodiment of the present invention, the anti-twist protection consists of a spring arm which extends in the tangential direction with respect to the adjustment element. This spring arm is attached to the adjustment element on one side or both sides and comprises a recess formed in the direction of the basic element which cooperates with a respective recess in the basic element. As soon as the adjustment element is screwed deep enough into the basic element, the first anti-twist protection blocks elasticity in the respective recess in the basic element to provide the aforementioned transport guard.
    [0012] According to an additional modality of the present invention, the second anti-twist protection, also denoted as safeguard or blocking protection, is a protruding membrane in the radial direction of the adjustment element that is preferably disposed inclined towards the basic element and which blocks an additional screwing of the adjustment element into the basic element. Such a membrane is preferably provided separately from the transport safeguard. It is also preferred to integrate the locking guard in the transport guard membrane.
    [0013] The second anti-twist protection is formed preferably compact, stable and inelastic, due to its functionality. In this way, the second anti-twist protection consists of a lock that prevents rotational movement of the adjustment element against further screwing of the adjustment element into the base element. For this purpose, preferably, the radially protruding membrane of the second anti-torsion protection engages a recess in the basic element adapted therein that prevents excessive screwing of this interlock connection due to the inelastic construction of the second anti-torsion protection and the adapted shape of the recess in the basic element. In this context, it is preferred that the radially protruding membrane of the second anti-torsion or blocking safeguard has a surface of upsetting or oriented compression almost radial with respect to the adjustment element by means of which a surface of at least one recess in the basic element can be limited. By definition, the orientation of the mentioned compression surface, the normal surface arranged on the compression surface, is observed, which is aligned according to the invention, preferably in the tangential direction with respect to the adjustment element. Preferably, the compression surface of the second anti-twist protection or blocking safeguard cooperates with a surface in the recess in the basic element which is arranged parallel or almost parallel thereto. The surfaces adapted in this way in their orientation with respect to each other ensure that a torque applied to the adjustment element is directed to the base element to prevent further screwing of the adjustment element into the basic element. According to an embodiment of the present invention, the normal surface of the pressing surface is arranged at an angle of less than 90o with respect to the longitudinal geometric axis of the adjustment element and thus, inclined in the direction of screwing in the basic element. In this way, it is ensured that the compression surface is aligned almost parallel with the contact surface in the recess.
    [0014] According to an additional preferred modality, the basic element comprises on a front surface that faces the adjustment element at least one, additionally, at least two are preferred, spaced apart from each other, preferably , 120o, which are engaged by the first and second anti-twist protection of the adjustment element at the same time. It is also conceivable to arrange these recesses in the basic element at a greater or lesser angular distance, with respect to each other, as long as the functionality of the first anti-torque protection and the second anti-supervision protection is guaranteed at the same time. According to an additional modality, only one recess is provided in the basic element that cooperates with safeguarding transport, as well as with safeguarding the lock due to its shape. For this purpose, the recess at least one preferably comprises a first and / or second surface, respectively, which are arranged at an angle, and not symmetrically in relation to each other. Certainly, it is also preferred, in the same way, to use surfaces for the recesses in the basic element that are arranged symmetrically in relation to each other. However, preferably, at least one of the surfaces of the recesses that are oriented at an angle with respect to each other is adapted to the orientation of the compression surface of the second anti-twist protection or blocking guard, so that this second surface of the recess, as well as the compression surface being aligned parallel or almost parallel with respect to each other. Therefore, and according to a preferred modality, the first recess surface is arranged at a greater angle than the second recess surface with respect to the longitudinal geometric axis of the basic element. According to an additional preferred embodiment, the recess, at least one extends over a specific range of rotation angle. The two ends of the recess that are spaced in relation to each other in the circumferential direction cooperate with the transport safeguard and the lock safeguard.
    [0015] With respect to the construction of the fixing arrangement, the adjustment element preferably consists of a construction of multiple parts featuring a central drag safeguard component. To provide a space-saving construction of the fixing arrangement, the central drag guard component comprises at least one radially and internally protruding drag arm, as well as the first and second radially and externally protruding anti-twist protection. The central drag guard component is constructed in such a way that at least one drag arm is arranged radially inside and the anti-twist protection radially outside the glove-shaped adjustment element. By means of this centrally dragging safeguard component, the production of the adjustment element is preferably simplified and the number of individual parts of the adjustment element is reduced.
    [0016] The adjustment element preferably also comprises a threaded sleeve and a disk, in which the drag guard component is fixed between the disk and the threaded sleeve by means of a fixing sleeve. Also, it is preferred to provide the adjustment element described above as a molding component, the injection of a part or multiple parts or, in general, as a plastic component.
    [0017] The present invention further comprises a connection between component A and component B that was produced by means of the fixing arrangement described above in combination with a fixing screw.
    [0018] Such connection is made by a method of mounting the fixing arrangement comprising the following steps: fixing the basic element in component A, screwing the fixing screw through an opening in component B and through the installed adjustment element on the basic element, so that tolerances between components A and B are automatically compensated and, where a release of at least the first anti-twist protection occurs between the basic element and the adjusting and trimming element - fixing the fixing screw firmly in the base element so that components A and B are fixed to each other.
    [0019] To ensure an efficient installation of the fixing arrangement between components A and B, the fixing arrangement is first pre-assembled before distribution. This method of pre-assembling the fastening arrangement comprises the following steps: screwing the adjustment element into the basic element, blocking the first anti-twist protection of the adjustment element in a first recess in the basic element and blocking the second anti-torque protection of the adjustment element in a second recess in the base element, so that blocking of the adjustment element and the base element is avoided. In this way, and preferably, according to the invention, the adjustment element is screwed sufficiently deep into the basic element, so that an installation between components A and B is prepared. At the same time, it is also prevented that the adjustment element is blocked with the basic element during pre-assembly, which would guarantee a loss-proof transport of the adjustment element in the basic element, but would require additional time. for releasing the connection between the adjustment element and the basic element during assembly of the fixing arrangement between components A and B. As a consequence, the pre-assembly method prepares an effective and time-saving installation of the fixing arrangement between components A and B. 4. Concise description of the attached figures

    [0035] Fig. 1 shows a preferred embodiment of the fixing arrangement according to the invention for fixing a component B to a component A with automatic tolerance compensation between components A and B. The fixing arrangement therefore comprises , a basic element 10 which is fixed in an opening of the component A. An adjustment element 30 is connected to the basic element 10 via a screw connection. According to the rotational direction of the adjustment element 30, the common axial length of the base element 10 and the adjustment element 30 varies, whereby tolerances between the two adjacent components A, B are compensable.
    [0036] In the mounting state of the fastening arrangement, the adjustment element 30 supports itself on the second component B. Components A and B, as well as the fastening arrangement 10, 30 are connected to each other via a mounting screw or fastening screw 80. Therefore, the fastening screw 80 is screwed into a threaded part 14 in the base element 10 (see below).
    [0037] Although the basic element 10 consists of plastic or metal, it is preferred to produce the basic element 10 of steel. This choice of material ensures sufficient stability, resistance to aggressive chemical, mechanical and thermal media and additionally ensures reliable fixing on component A. Preferably, basic element 10 is made as lock nut, welding nut or blind rivet nut. It is additionally preferred to fix the basic element 10 as a nut having an external thread on component A. According to an additional alternative, basic element 10 is glued to the opening of component A.
    [0038] As can be seen from Figures 2 and 6, the basic element 10 comprises an internal thread part 14 showing a first direction of the thread cooperating with the thread of the fixing screw 80. Adjacent apart from thread 14, the inner side of the basic element 10 comprises an inner thread 12 having a second direction of the thread opposite the first direction of the thread. The internal thread 12 cooperates with an external thread 42 of a sleeve 40 of the adjustment element 30. It follows that when the fastening screw 80 is screwed in the part with thread 14, the adjustment element 30 is screwed out of the element basic 10 through the second thread pairing. A rotation of the adjustment element 30 together with the fastening screw 80 is carried out by means of at least one dragger 56 which makes a friction connection between the adjustment element 30 and the fastening screw 80.
    [0039] The basic element 10 comprises at its end facing the adjustment element 30 a front surface 16. Preferably, a plurality of recesses 20 is formed on its front surface 16, preferably at least two notches that are spaced apart ( offset) with respect to each other by 120o. According to a preferred embodiment, a circumferential flange 18 provides the front surface 16 in which three notches 20 are provided, which are equally spaced from each other. It is also preferred to form the notches 20 without a circumferential flange 18 on the front surface 16 of the basic element 10.
    [0040] According to an additional preferred mode (not shown) only a recess 20 is provided in which the first and second anti-twist protection (see, below) take effect. For this purpose, for example, this indentation 20 extends over a specific angle of rotation range to ensure a secure engagement of the first and second anti-twist protection in this indentation, even with clearance. According to a further preferred embodiment of the present invention, an arbitrary number of recesses 20 is provided, which are spaced from one another equally or not equally. This plurality of recesses 20 is preferably arranged, so that the first and second anti-twist protection (see, below) engages the recesses 20 simultaneously, or with a convenient protrusion with respect to each other.
    [0041] These notches 20 cooperate with the first and second anti-twist protection 52, 54 which serve as a transport safeguard 52 of the adjustment element 30 in the basic element 10 and as a lock safeguard 54 between the basic element 10 and adjustment element 30 (see below).
    [0042] According to figures 2, 3 and 10, the adjustment element 30 preferably consists of a sleeve with thread 40 which is connected with a disc 60 through a pressed sleeve 70 and a drag guard component 50. The threaded sleeve 40 has an external thread 42 that cooperates with the internal thread 12 of the basic element 10. As already mentioned above, the internal thread 12 and the external thread 42 have the second direction of the thread that is opposite the direction of the thread of the first thread match between the fixing screw 80 and the threaded part 12. The adjustment element 30 supports itself in component B through the disc 60, as shown in Fig. 1. Disc 60 and the sleeve with a 40 thread consist of metal, preferably steel, in which oriented application also uses other metals or plastics. Although a multi-piece construction is preferred here, the adjusting element 30 can also be provided as a one-piece plastic component.
    [0043] According to Figure 10, the disc comprises an internal opening 62 having a chamfered part 64. Preferably, the chamfered part is knurled so that the interference fit of the pressed sleeve 70 in the opening 62 is supported. The pressed glove 70 also comprises a circumferential part, preferably structured 72, supporting a friction connection between the pressed glove 70, drag guard component 50 and threaded glove 40. Pressed glove 70 is forced into the threaded glove 40 in the axial direction by means of opening 62 and by means of the curved toroidal safeguard component, preferably 50, and is fixed by means of a friction connection. In this way, the disc 60, the drag guard 50 and the threaded sleeve 40 are connected with each other reliably and form the adjusting element 30.
    [0044] The drag guard component 50 preferably consists of an elastic material such as spring steel to ensure the functionality of the drag arms 56 (see below). In this context, it is preferred to manufacture the drag guard component 50 as a perforated and arcuate part. Alternatively, for this purpose, all other elastic materials are usable.
    [0045] In Figures 3 and 5, the following details are visible: at least one dragging arm 56 inside the adjustment element 30, the pressed sleeve 70, as well as the two anti-torque protections 52, 54. Both anti-torque protections 52 , 54, serve as a transport safeguard 52 for fixing the basic element 10 and the adjusting element 30 with each other and as a locking safeguard 54 to prevent a hard or non-releasable screwing of the adjustment element 30 on the basic element 10. As part of the drag safeguard component 50, the transport safeguard 52 and the lock safeguard 54 protect in addition to the radial outer edge of the threaded sleeve 40 between the threaded sleeve 40 and the disc 60 (according to Figures 6, 7, and 8, 9).
    [0046] Preferably, the transport safeguard 52 and the lock safeguard 54 are spaced from each other by an angle around 120o, in which the safeguard safeguard 54 is located upstream of the transport safeguard 52 observed in the direction of screwing I of the adjustment element 30 in the base element 10. The transport safeguard 52 and the lock safeguard 54 can preferably also be arranged spaced at a greater or lesser angle as 120o with respect to each other. It is also preferred to carry out the transport safeguard 52 and the lock safeguard 54 on only one radial protruding member of the adjustment member 30 to support a compact pattern or structure.
    [0047] The transport safeguard 52 and the lock safeguard 54 cooperate with at least one indentation or notch 20 (see above), which are spaced from each other according to the angular distance of the transport safeguard and the lock safeguard 54 to ensure simultaneous engagement of transport safeguard 52 and lock safeguard 54 each, in a recess, or in a common notch 20. It is also preferred that the transport safeguard 52 and the locking safeguard 54 engages in recesses 20 which are spatially displaced with respect to each other. This engagement occurs simultaneously, or with protrusion (offset) with each other.
    [0048] According to a preferred embodiment shown in Figures 7 and 9, the notches 20 consist of two surfaces 22, 24 angled at each other. According to one embodiment of the present invention, these surfaces 22, 24 are formed and arranged not symmetrically from each other, in which also a arrimetric arrangement of the surfaces 22, 24 can be used.
    [0049] According to an embodiment of the present invention, the surface 24 of the groove 20, which is located upstream in the direction of screwing I is arranged at a smaller angle β with respect to the longitudinal geometric axis L of the basic element 10 compared to the surface 22, which is arranged at angle α with respect to the longitudinal geometric axis L of the basic element 10. This alignment of the surface 22 supports a release of the transport safeguard 52 during assembly of the fastening arrangement between components A and B.
    [0050] Additionally, the surface 24 which is more steep (steeper) with respect to the longitudinal geometric axis L of the element 10 provides a locking plane for safeguarding the lock 54 (as shown in Figure 9). It is also preferred to extend the groove / recess 20 shown in Fig. 9 over a specific circumferential part (not shown). A notch / recess thus formed 20 ensures the simultaneous engagement of the transport safeguard 52 and the lock safeguard 54, in which the transport safeguard 52 and the lock safeguard 54 can be performed on only one common radial membrane or in two separate radial membranes. The circumferentially extended recess / notch 20 provides a specific rotating clearance (clearance) between the adjustment element 30 and the basic element 10.
    [0051] The transport safeguard 52 is preferably formed as an elastic membrane 52 radial and protruding externally with respect to the outer edge of the sleeve with thread 40. To support the elastic mobility of the membrane 52 and thus its blocking in the notch 20, the membrane 52 preferably extends in the tangential direction with respect to the sleeve with thread 40 and opposite to the direction of screwing I. It is also preferred to have the membrane (web) 52 that extends tangentially in the direction of screwing I. The membrane 52 furthermore, according to one embodiment, it comprises a wavy protrusion directed towards the basic element 10 which engages the respective notch 20. This wavy shape of the membrane 52 ensures that the membrane 52 can enter the notch 20 on both sides without any problems, meaning in a clockwise rotation and in a counterclockwise rotation of the adjustment element 30.
    [0052] A modality of the locking safeguard 54 is shown in Figure 9. The locking safeguard 54 is also a radially and externally protruding membrane with respect to the threaded sleeve 14. The locking safeguard 54 is preferably disposed in the direction of the basic element 10, so that the locking guard 54 delimits an angle <90 ° with the longitudinal geometric axis L of the adjustment element 30. In addition, the locking guard 54 comprises a compression surface 55, the normal surface of which extends almost in the tangential direction with respect to the threaded sleeve 40. When the adjusting element 30 is screwed into the basic element 10 and the locking guard 54 thus moved in the direction of the recess 20, the pressing surface 54 is limited to a specific angular position on the surface 24. In this way, an additional screwing and locking of the adjusting element 20 in the basic element 10 are blocked . This locking function is preferentially and ideally when the pressing surface 52 and the surface 24 are arranged parallel to each other.
    [0053] Additionally, it should be considered that preferably, the locking guard 54 is arranged in a radial plane that is more spaced from the disc 60, like the radial plane in which the transport guard 52 is arranged. In this way, the blocking safeguard 54 locks effectively and reliably against a blocking of the adjusting element 30 and basic element 10, while at the same time an easy release lock of the transport safeguard 52 in the chamber 20 is ensured.
    [0054] From the above described construction of the fixing arrangement and its results from individual components, the following method of pre-assembling the fixing arrangement for preparing the future installation of the fixing arrangement between the two components A and B. - firstly, the adjustment element 30 is screwed on the basic element 10 (step A1). After the adjustment element 30 has been screwed into a sufficient depth in the base element 10, the first anti-twist protection, especially the transport safeguard 52, of the adjustment element 30 locks or fits in the first recess or notch 20 in the base element 10 (step A2). As the adjusting element 30 can be screwed in additionally, to the basic element despite the lock or pressure of the transport safeguard 52 in the slot 20, a lock of the second anti-twist protection or lock guard 54, respectively, of the adjustment element 30 in a second recess or notch 20, respectively, in the element 10 follows after additional screwing in the adjustment element 30 in the basic element 10, so that the locking of the adjustment element 30 and the basic element 10 is avoided (step A3) (according to the flowchart according to Fig. 13).
    [0055] The compact and space-saving construction of the adjustment element 30 is based, in part, on the use of the drag guard component 50 (according to Figs. 10 to 12). Preferably, the drag guard component 50 is drilled as a straight piece that extends, according to Fig. 11, from a flexible and bent or curved metal. Preferably, the drag guard member 50, according to Fig. 11, consists of spring steel while other robust elastic materials are suitable. The drag guard component 60 is therefore preferably present as a perforated and curved part made of spring steel.
    [0056] To simplify the manufacture or production of the fastening arrangement, firstly the drag guard component 50, according to Fig. 11 is drilled and bent or bent. Therefore, the open annular or toroidal shape of the drag safeguard component 50 is created, according to Fig. 12. That drag safeguard component 50 preferably formed with a toroidal shape comprises the drag arms. ment 56 presenting a wavy shape, with radial protrusion and inwardly directed (as shown in Fig. 12). According to one embodiment, the drag guard member 15 comprises at least one drag arm 56 which is disposed within the threaded sleeve 40 after assembly. It is additionally preferred to have two or three drag arms 56 on the sleeve with thread 40. In the installed state, draggers 56 reduce the internal width of the sleeve with thread 40, so that its internal diameter is less than one outer diameter of the clamping screw 80. In this way, the clamping screw 80 rotates or rotates the adjustment element, provided that the adjustment element 30 is in contact with component B.
    [0057] On the side facing the disc 60, the drag guard 50 comprises an open circumferential toroidal strip 55 to which the drag arms 56 and the anti-torque guards 52 and 54 are attached. The toroidal strip 55 has a polygonal shape to simplify its production and can therefore be adapted to any arbitrary opening. In addition, and by folding or bending the polygonal shape, the toroidal strip 55 is prevented from returning to the spring shape, that is, it deforms back to the straight shape according to Fig. 11
    [0058] In the toroidal shaped strip 55, a circumferential toroidal collar 58 is arranged on the side that faces out of the entrainer. This toroidal collar 58 consists of small tails equally spaced or radially and externally protruding, which will be kept in the future adjustment element 30 between the disc 60 and the threaded sleeve 40 in a clamping manner. The drag guard component is fixed through the pressed sleeve 70 fixing the toroidal collar 55 between the disk 60 and the threaded sleeve 40, as well as the toroidal shaped strip 55 between the pressed sleeve 70 and the inner wall of the sleeve with thread 40. From that, a stable and releasable arrangement of the drag arms 56, as well as the anti-twist protections 52, 54 in the results of the fixation arrangement.
    [0059] For assembly or installation, the fixing arrangement according to the invention, between the two components A and B, the following steps are necessary. First, preferably, the fastening arrangement consisting of adjustment element 30 and basic element 10 is transported to the buyer. The transport safeguard 52 and the lock safeguard 54 have an effect on this one or the other. At the purchaser, the basic element 10 is installed, mounted or attached to component A (step B2), in which the adjustment element 30 has been released from the basic element 10 and thus also the transport guard 54 and / or the backup lock 54 previously (option B1). Therefore, preferably, the adjusting element 30 is installed again in the basic element 10 to be able to transport the entire arrangement for component B guaranteed by the transport safeguard 52 and / or the lock safeguard 54.
    [0060] In step B3, the fixing screw 80 is screwed into the basic element 10 through an opening in the component B and through the adjustment element 30, installed in the basic element 10, so that tolerances between the components A and B are compensated automatically. At the same time, the transport safeguard 52 and / or the lock safeguard 54 are released at the beginning of this procedure (B1). In step B4, tightening the fixing screw 80 on the element 10 takes place so that components A and B are fixed to each other (as shown in Figure 14).
