    1. FIELD OF THE INVENTION
    [0001] The invention relates to a fixing device for fixing a first component to a second component, with automatic compensation of tolerances between these components; in addition, a component with a fixture installed, and a method of installing a fixture. 2. BACKGROUND OF THE INVENTION
    [0002] Numerous types of fixing devices with tolerance compensation are known. Typically, they are comprised of an adapter sleeve with a so-called "transport section" or "drag section" that can enter a connection locked by friction to a set screw. When the fixing screw is turned, the adjustment bush is turned together with it, until said bush supports against one of the two components that are arranged at a distance. When the fixing screw is turned further, with the corresponding increase in torque, the friction-locked connection between the fixing screw and the transport or drag section is overcome, so that the two components can then be forced together by the fixing screw, using an adjustment sleeve.
    [0003] EP 1666342 B1 describes this fixing device, with a transport or drag section arranged over the fixing screw. In particular, the transport section is comprised of a deformed thread region that cannot be screwed into the internal thread of the compensation element. Therefore, first the compensation element is rotated together with the fixing screw, by said fixing screw. Only when the compensation element rests against a component, can a blocked torque be overcome, so that the deformed thread region enters the compensation element thread. In addition, for the transport or drag element itself, the tolerance compensation element has a design that consumes space in both the radial and axial directions, so that a correspondingly large installation space between the two components needs to be provided .
    [0004] EP 1260717 discloses a fixing device in which the fixing screw also carries the compensation element along with it as it rotates. This co-rotation is carried out, for example, in which the thread of the fastening screw is coated with a friction agent or the like, so that a high torque is required to screw the spinning screw into the thread of the compensation element. Thus, the compensation element is rotated together with the fixing screw, until the compensation element rests against the opposite component.
    [0005] In the fixing device of WO 2010/066363 A1 a compensation element is provided, the inner side of which is similar to that of a transport sleeve. This plastic transport bushing provides a friction-locked connection for the fixing screw, as a result of its reduced diameter compared to the outside diameter of the fixing screw. On this base, the fastening screw rotates, carrying the compensation element with it, until the compensation element rests against the opposite component. This plastic bushing for transport along the compensation element has an internal thread that is smaller than the external thread of the fixing screw. Therefore, a higher torque is required to screw the fixing screw into this plastic bushing, so that the fixing screw initially rotates carrying the compensation element with it. This fixing device also requires a large accommodation space in both the radial and axial directions, so that it is disadvantageous in a situation where space savings are required. Also, the fixing screw must pass completely through the plastic bushing during installation, which increases the time required for installing the fixture, due to the increased torque. If the plastic bushing is too short or too soft, the fixing screw can be passed through disadvantageously.
    [0006] Based on the state of the art discussed above, the underlying problem of the present invention is to provide a fixing device for fixing a component B to a component A with automatic tolerance compensation in the distance between the two components, whose device requires a space of small accommodation and installable at low cost compared to the state of the art. 3. SUMMARY OF THE INVENTION
    [0007] The underlying problem above is solved by a fixing device for attaching a first component to a second component with automatic tolerance compensation in the distance between the first component and the second component according to independent claim 1, by a component with a fixing device installed according to claim 11, and by an installation method for the fixing device according to claim 12. Modalities, variants, modifications and other further developments of the invention are described in the dependent claims and the report in combination with the drawings.
    [0008] The fixture of the invention has the following characteristics: a retaining element and an adjustment element, which are screwable together through an external thread of the retaining element and an internal thread of the adjustment element, in a first match thread with a first thread direction, where the fixing screw is screwable into the retaining element by a second thread match with a thread direction opposite to that of the first thread direction, the fixing screw of which can be connected releasable to the adjustment element by means of a transport or drag element, so that the fastening screw is rotated, the adjustment element is rotated together with it, for the purpose of tolerance compensation, by moving the adjustment element in support against the second component, where the transport or drag element has a spring loaded ring that is spring loaded in the axial direction of the adjustment element, and the transport or drag has a thread of the transport element and a thread lockable means of the transportable element.
    [0009] The fixation device of the invention provides a design that consumes less space than the state of the art, whose device of the invention is distinguished by smooth and easy installation, and effective tolerance compensation. The connection of the retaining element and the adjusting element via an external thread of the retaining element provides a compact arrangement. The design of the special transport element based on a spring loaded ring with a thread of the transport or drag element, and a thread locking means of the transport element provides reliable rotational transport of the adjustment element with the rotational movement of the fixing screw. The thread of the transport element ensures that the fixing screw cannot be compressed through the transport element. In addition, the transport element provides a reliable coupling to the fastening screw, so that after the thread of the transport element enters the thread of the fastening screw, a rotational movement of the fastening screw is immediately transmitted to the adjustment element, for obtain effective tolerance compensation. In addition, the combination of the thread of the transport element and the thread locking means of the transport element in the transport element serves to prevent the high frictional forces preventing (or making it more difficult) the rotation of the fastening screw inside the transport element, thereby prolonging the installation time of the fixing device.
    [0010] According to a preferred embodiment of the fixture, the thread locking means of the transport element in combination with the thread of the transport element is in the form of an undersized thread compared to the thread of the fixing screw, so that a nominal diameter of the thread of the clamping screw is greater than a nominal diameter of the thread of the transport element. Because the undersized thread of the transport element has a nominal diameter smaller than the thread of the fixing screw, a threshold torque between the transport element and the fixing screw needs to be overcome in order to screw the fixing screw into the fixing element transport. As long as this threshold torque is not reached, the clamping screw rotates the adjustment element along with it on the transport element, and thus adjusts the distance between the first and second components. Only when the adjustment element comes to support against the second component does the torque above the clamping screw and the transport element increase above the threshold torque value, and the clamping screw is screwed into the retaining element.
    [0011] According to an embodiment of the fixation device of the invention, the transport element has a fixing ring that can be attached to the adjustment element, preferably by compression. It is also preferable if the spring loaded ring of the transport element is arranged on the fastening ring through at least two projections extending in the radial direction.
    [0012] The thread of the transport element of the transport element is adjusted to the thread of the fixing screw. The fact that the ring on the fastening ring is spring loaded ensures that the transport element and thus the thread of the transport element are movable in spring loaded mode in the axial direction, so that the transport element is automatically moved in an axial insertion position adjusted to insert the rotating fixing screw into the thread of the transport element and / or into the internal thread of the retaining element. Due to the automatic adjustment between the thread of the fastening screw and the thread of the transport element, the fastening screw enters the transport element almost without friction.
    [0013] The thread locking means of the transport element of the transport element locks earlier than the fixing screw, so that the rotation of the fixing screw is transferred to the adjusting element. In addition, the fixing screw does not need to cut any threads on the transport element.
    [0014] According to another preferred embodiment of the invention, the thread of the transport element has a maximum of one turn of the thread, at a maximum rotation angle of 360 °. It is also preferred to thread the transport element at a rotation angle of less than 360 °, provided that reliable adjustment of the adjustment element by the fixing screw is guaranteed. Consequently, the threads of the transport element are employed, which extend at a rotational angle of 0-270 °, preferably 0-180 °.
    [0015] According to another embodiment of the invention, the thread locking means of the transport element of the transport element is comprised of a detent or cam extending radially inward. Another alternative form for the thread locking means of the transport element comprises an axially extending projection, which locks the thread of the transport element against another rotational penetration by the fixing screw. Both the detent extending radially inward and the projection extending axially are irreversibly deformable radially outward or displaceable radially outward, so that when a torque threshold is exceeded, the thread locking means of the transport element it can be overcome with the aid of the fixing screw, so that the fixing screw will be able to be screwed further away. The holder (or the projection) is preferably arranged close to the thread exit of the element and transport.
    [0016] According to yet another preferred embodiment of the clamping device, the retaining element has at least one closing recess at one end facing the transport element, so that the adjustment element is released against rotation , through a spring loaded arm extending circularly arched or tangentially with the closing projection, on the fixing ring, or an axial closing projection on the spring loaded ring. With this arrangement, transport security for the fixing device is provided.
    [0017] According to another embodiment of the invention, the retaining element has a rivet collar by which the retaining element is fixable on a guide of the first component. This type of fixing of the retaining element allows a space-saving connection, so that the retaining element is finished flush with the first component.
    [0018] In addition, the fixing device of the invention in one of the configurations described above preferably has the fixing screw.
    [0019] In addition, the invention comprises a component with the fixing device installed according to one of the alternatives described above.
    [0020] Additionally, the invention comprises a method of installing a fixture between a first component and a second component, with automatic tolerance compensation in the distance between the first component and the second component, in which the fixture has a retaining element, an adjustment element, a fastening screw, and a transport element, with a spring loaded ring which is spring loaded in the axial direction of the adjustment element, with a thread of the transport element, and a means thread locking of the surpassable transport element. The installation method comprises the following steps: - the retaining element is attached to the first component, where the adjustment element is pre-assembled on the retaining element; - the spring loaded ring is positioned axially with the aid of the fixing screw, so that the fixing screw can be screwed into the thread of the transport element that has the thread locking means of the surpassable transport element, and / or on the internal thread of the retaining element; - the fixing screw is screwed onto the thread of the transport element; - the adjustment element is rotated by means of the transport element with the fixing screw, until the distance between the first component and the second component has been adjusted; and - the locking means of the transport element is overcome by turning the fixing screw and screwing the fixing screw on the retaining element, so that the first component is now fixed to the second component.
    [0021] In another preferred embodiment of the installation method, when the thread locking means of the transport element is overcome, the fixing screw radially outwardly displaces a projection holder radially inward or a projection extending axially. It is further preferred that the detent extending radially inward is irreversibly deformed radially outwardly by the clamping screw, i.e., compressed reversibly radially outwardly. 4.

    [0035] The fixing device illustrated in figures 10 and 11 serves to fix a first component B1 to a second component B2. The second component B2 is, for example, a support for a motor vehicle, while the first component B1 is a part of a headlight housing fixed by fixed position. According to another modality, the first component B1 is a guide rail for a sliding roof, which is fitted to the vehicle frame, as well as the second component B2. The first component B1 and the second component B2 are at a distant distance S, which can vary based on tolerances related to the conditions of assembly and / or manufacturing. The illustrated fixture allows automatic adjustment of these tolerances.
    [0036] The fixture is comprised of a retaining element 10, an adjusting element 30, and a fixing screw 70. The retaining element 10 and the adjusting element 30 form a pre-mountable component unit E, as illustrated in an exploded view in figure 5.
    [0037] The retaining element 10 in particular is illustrated in figures 1, 3 and 5. The one-piece retaining element 10 is comprised of a glove-like body which at one axial end has a flange 12 and at the other axial end undergoes a transition to a cylindrical recess 14. The sleeve-like body of the retaining element 10 extending between the flange 12 and the cylindrical recess 14 has an internal thread 16 on a radially internal side which, in particular, can be a thread on the right side that matches the thread of the fixing screw 70 (see figure 2). On the radial outer side of the sleeve-like element of the retaining element 10 an external thread 18 is provided which equals a radially internal thread on the adjustment element 30.
    [0038] The external thread 18 of the retaining element 10 and the internal thread of the adjusting element 30 form a first thread match with a first thread direction. The thread of the fastening screw 70 and the internal thread of the retaining element and the transport element 50 form a second thread match with a thread direction which is opposite to that of the first thread match. These two thread pairings with opposite thread directions ensure that when the fastening screw 70 is being screwed into the fastening device the adjustment element 30 is screwed out of the fastening element 10 as far as the distance S between the two components B1 and B2 is offset.
    [0039] The retaining element 10 is preferably made of metal, preferably steel or other material that is reliably deformable and thus fixable. According to a preferred embodiment, the retaining element 10 is attached to the first component B1 with the aid of a rivet collar 20. In the non-installed state, the rivet collar 20 extends in the axial direction of the retaining element 10, as illustrated, for example, in figures 10 and 11. The rivet collar 20 can be fixed to a guide of the first component B1 or to an opening with a countersink so that the rivet collar 20 is closed without flushing with the upper side of the first component B1. An example of such an arrangement is shown in figure 1. The rivet collar 20 is preferably rotated backwards with the principle of an oscillating rivet, so that it is fixed to the guide or opening in the first component B1. In this way, the first component B1 is retained between the rivet collar 20 and the flange 12 of the retaining element.
    [0040] The end of the retaining element 10 which is opposite the flange 12 carries the cylindrical recess 14. The cylindrical recess 14 is connected on one side by the axial outer end face 22 and on the other side by the axial inner end face 24. According to the preferred embodiment shown in figure 5, the axial outer end face 22 has locking recesses 26. It is preferred to provide these locking recesses 26 on the axial inner end face 24 or both end faces (22, 24) (not shown). One or more lock projections 64 of the transport element 50 engages the first lock recesses 26, so that the adjustment element 30 once screwed into the retaining element 10 is held against rotation. This safe anti-rotation that resists rotation only up to a certain threshold torque value, serves as a means of securing the pre-assembled module comprised of the retaining element 10 and the adjusting element 30 with the transport element 50 during transport, and also serves as a security lock element.
    [0041] The adjusting element 50 is preferably comprised of a glove-like base body made of metal, preferably steel. It is conceivable to employ other materials, such as, for example, stable plastics, as long as they meet the mechanical stability requirements for the fixture. The internal thread 32 of the adjustment element 30 is preferably a thread on the left side which is equal to the external thread 18 of the retaining element 10. In addition, the adjustment element 30 has a cylindrical recess 34 at an axial end. The transport element 50 is compressed within this recess 34, where it is held by the force, i.e., a non-positive fit. It is preferable if the transport or drag element 50 is retained in the cylindrical recess by adhesion or another appropriate means of fixing it there.
    [0042] The adjustment element 30 has a conduction means 36 on its radial external side. Preferably, the driving means comprises two diametrically opposed parallel surfaces, allowing the adjustment element 30 to be rotated by a wrench at the open end. Such a driving means 36 is useful when the adjusting element 30 must be released from an installed position.
    [0043] The transport element 50 is retained in the cylindrical recess 34 of the adjusting element 30. The transport element 50 is preferably comprised of plastic, but can be comprised of metal, as long as the transport element 50 can be fixed securely. reliably in the cylindrical recess 34. The transport element 50 is comprised of a spinning ring 52, as shown in figures 6, 7 and 8. The fixing ring 52 has an axial extension that equals the cylindrical recess 34 in the adjustment element . In addition, the outer diameter of the fixing ring 52 is established so that the ring 52 can be compressed within the cylindrical recess 34. This compression fit between the cylindrical recess 34 and the fixing ring 52 produces a forced connection, so that the transport element 50 and the adjustment element 30 are reliably interconnected. To support this connection, the fixing ring 52 has a radially outward cord 51 having an external cross section that is larger than the inside diameter of the cylindrical recess 34. In addition, the fixing ring 52, at its outward facing end of the cord 51, is inclined radially inward, so that the inclination helps to insert the fixing ring into the hollow cylindrical recess 34.
    [0044] As seen from figure 6, a ring 54 is arranged in spring loaded mode radially inside the fixing ring 52. The spring load is facilitated with the help of the projections 56, through which the ring 54 is connected to the fixing ring 52. At least two of the projections 56 are necessary in order to reliably retain the spring loaded ring 54 in the fixing ring 52. The projections 56 are of such a thickness that the ring 54 can change its axial position. For example, the fastening screw 70 when not yet screwed into the spring loaded ring 54 compresses the ring 54 in the appropriate axial position so that the fastening screw 70 can engage the thread 58 of the transport element. According to another variation, the fixing screw is screwed into the spring loaded ring 54. In order to pass into the internal thread 16 of the retaining element 10, the fixing screw 70 moves the spring loaded ring in the axial direction. This axial movement can be in the direction or outside of the internal thread 16. Then the fixing screw also enters the internal thread 16 of the retaining element 10.
    [0045] It is also preferred to have more than two projections 56 to connect the spring loaded ring 54 to the fixing ring 52. The projections 56 are illustrated in figure 7, which is a partial cross section through line B-B in figure 6.
    [0046] According to a preferred embodiment, the spring loaded ring 54 has a thread 58 on its inner radial side, the thread of which is adjusted to the external thread of the fixing screw 70. The thread 58 of the spring loaded ring 54 has only a turn, extending at an angle of a maximum of 360 °. Preferably, the extension of the thread 58 is above a minor angle of, for example, 0-270 °, particularly preferably 0-180 °. This turn of the thread ensures that the fixing screw 70 will enter the transport element 50 without friction. If the axial position of the thread turn 58 of the spring loaded ring 54 is not adjusted to the thread of the set screw 70, the set screw 70 will automatically compress the spring loaded ring 54 into the appropriate axial position so that the thread turn 58 can enter the thread of the fixing screw 70. Consequently, with the turn of the thread 58 adjusted in its shape to the threads of the fixing screw 70, a connection in the interlocked form will be created between the spring loaded ring 54, the transport 50, and the clamping screw 70. This connection ensures that the torque applied to the clamping screw will also be transmitted to the transport element 50 and thus to the setting screw 30. Through this torque transmission, the setting element 30 is cannot be unscrewed from the retaining element 10 until the distance S between the first component B1 and the second component B2 is set.
    [0047] In the end region of the thread turn 58, the inner radial side of the spring loaded ring 54 preferably has a stop or cam 60 that extends radially inward. The detent 60 ensures that the fixing screw 70 can be screwed into the turn of the thread 58 only as much as the detent 60. As long as the torque of the fixing screw 70 does not exceed a threshold value in relation to the transport element 50, the detent 60 acts a block on the thread of the transport element. Consequently, the transport element 50 and thus also the adjustment element 30 are rotated together with the fixing screw 70. The means for locking the transport element 60 can be any means that prevents further insertion of the fixing screw 70 in the rotation of the thread 58. Thus, for example, a projection in the axial direction of the spring loaded ring 54 can block the rotation of the thread 58, so that the transport element 50 is carried together by the fixing screw 70. Another embodiment of a means of locking the thread of the transport element 60 consists of a spring loaded projection (not shown) that extends radially into the spring loaded ring 54. This radial projection is preferably tilted in the tangential direction in the direction of rotation of the screw fixation 70. If the radial projection is loaded with the threshold torque, it will be spring loaded radially outwards, in order to free the rotation of the thread 58. After removing the fixation screw 70, it it is spring loaded radially inward to again provide the means for locking the transport element 60 onto the thread of the transport element. Thus, it is unnecessary to replace the transport element in case of new use.
    [0048] In this connection it is also preferred to form a detent 60 in such a way that it is reversibly displaced, radially outward by the fixing screw 70. Towards this end, the ring 54 is deformable and its internal diameter is greater than the nominal thread diameter of the fixing screw 70. If the threshold torque is exceeded. Or if the adjusting element rests against the second component B2, and the fixing screw 70 compresses the holder 60 radially outwardly, the ring 54 is deformed from its round shape to an oval shape. This deformation is such that the holder 60 frees the interior of the ring 54, and the fixing screw 70 can be screwed further into the thread 58 of the transport element.
    [0049] It is also preferred for the fixing screw 70 to be able to irreversibly deform the holder 60 radially outwardly, when the fixing screw 70 exceeds the threshold torque with respect to the transport element 50. In this case, the fixing screw 70 compresses the holder radially outwardly, where the holder 60 frees the inside of the ring 54, but is not separated from the transport element 50.
    [0050] According to another preferred embodiment of the invention, the thread of the transport element 58 and the thread locking element of the transport element 60 are designed together in a thread that is undersized with respect to the thread of the fixing screw 70. Because the undersized thread is not congruent with the thread of the fixing screw 70, in particular because it has a nominal diameter smaller than the nominal diameter of the fixing screw 70, when the fixing screw 70 is rotated into the undersized thread, the screw 70 becomes attached, so that the adjustment element 30 rotates with it, through the transport element 50.
    [0051] As soon as the fixing screw 70 rotates the adjustment element 30 with it through the transport element 50, as long as the distance S between the first component B1 and the second component B2 has been adjusted, the adjustment element 30 with its end side directed towards the transport element 50 rests against the second component B2. In this way, further rotation of the adjusting element 30 is prevented, so that when the adjusting screw 70 is turned further away, the torque between the thread locking element of the transport element 60 and the fixing screw 70 is increased. As soon as this torque exceeds the threshold value mentioned above, the fastening screw is screwed further into the fastening device through the thread locking element of the transport element 60. As soon as the fastening screw 70 is screwed firmly on the internal thread 16 of the rotation element 10, or is secured with a screw nut (not shown), there is a fixed connection between the first component B1 and the second component B2 through the fixing device (see figures 10 and 11).
    [0052] Figure 8 is a cross-sectional view through line AA in figure 6. You can see the spring loaded projection 62 (in the circumferential direction) from figure 6, one end of which is fixed on the ring of fixing 52 and the other end of which carries a closing projection 64. Thus, the closing projection 64 is spring loaded in the axial direction. It cooperates with at least one locking recess 26 (see figure 5) on the axial outer end face of the retaining element 10. If the adjusting element 30 with the compressed transport element 50 is rotated on the retaining element 10, the lock projection 64 of the transport element 50 locks (preferably) in one of the three lock recesses 26 in the retaining element 10. As a result of this locking engagement, the adjustment element is protected from being held by the locking element retaining 10 (being fixedly engaged) by the retaining element 10. Furthermore, said closing engagement between the closing projection 64 and the closing recess 26 provides security for transportation purposes, against an automatic detachment of the adjustment element 30 to from the retaining element 10.
    [0053] According to the preferred embodiment illustrated in figure 5, the closing projection 64 is arranged on the spring loaded projection 62 and cooperates with the closing recesses 26 on the axial outer end of the retaining element 10. It is also preferred arrange the lock projection 64 (not shown) on the axial end face of the spring loaded ring 54 which faces the adjustment element 30. In order to provide a locking engagement with the lock projection 64, then the hair at least one closing recess 26 is provided on the inner axial end face 24 of the retaining element 10. Because the spring loaded ring 54 with the closing projection 64 (not shown) is spring loaded and displaceable in the axial direction, the adjusting element 30 is releasably latchable to the retaining element 10 through the spring loaded ring 54. This closing engagement can provide security against the fixed engagement and security for transport purposes. As soon as the fastening screw 70 is screwed into the fastening device, the spring loaded ring 54 is released by a pressure in the axial direction from the fastening screw 70, from the closing engagement between the closing projection 54 and the closing recess 26, because it jumps out of the retaining element in the axial direction. After detaching the locking coupling, the fixing screw 70 can transport the adjustment element 30 in rotation with it, in the manner described above, in order to adjust the distance S between the first component B1 and the second component B2.
    [0054] Figure 9 shows an enlarged view, a cross section through the first component B1. This first component B1 has an opening in the form of a guide or a submerged hole, so that the rivet collar 20 (see figures 1, 10 and 11) can be locked in the grooves (or recesses) in this opening. To this end, the rivet collar 20 is folded back using the oscillating riveting technique, so that component B1 is retained between the flange 12 and the folded rivet collar 20.
    [0055] Figure 12 shows a flow diagram of a preferred embodiment of the installation process for the fixing device. It comprises the following steps: The first retaining element 10 is attached to the first component B1 (step I). For this purpose, the rivet collar 20 is preferably returned in an opening or guide 80 of the first component B1. According to one embodiment, the principle of an oscillating rivet is used for it. However, other methods can also be used that fix the retaining element 10 even on the rivet collar 20 at the opening of the first component B1. This is done, for example, by screwing or connecting or by another riveting technique.
    [0056] The retaining element 10 is attached to the first component B1 as a pre-assembled unit, that is, with the adjustment element 30 being screwed into, preferably with a locking latch. Then, the spinning screw 70 is oriented through an opening in the second component B2 and is applied to the spring loaded ring 52 of the transport element 50. In order to ensure the entry of the fixing screw 70 in the thread of the transport element 58 of the modes described above, the spring loaded ring 54 is positioned in the axial direction of the fixing screw 70 (step II). The fixing screw 70 compresses the ring 54 in an appropriate axial position, so that the fixing screw 70 can be screwed into the thread of the transport element 58 with the thread locking means of the surpassable transport element 60. Then (step III) follows the screwing of the fixing screw 70 inside the thread of the transport element 58.
    [0057] By the additional rotation of the fixing screw 70 (in step IV), the adjustment element 30 is also rotated through the transport element 50, and is moved in the axial direction to the second component B2. In this way, the distance S between the first component B1 and the second component B2 is adjusted. As soon as the adjusting element 30 rests against the second component B2, when the fixing screw is turned further apart, the torque between the fixing screw 70 and the transport element 50 increases. As soon as the threshold torque is reached, the fixing screw 70 overcomes the locking means of the transport element 60, which is in the form of a stop 60, a projection, or an undersized thread (see above) (step V or VI) . In this way, the detent 60 extending radially inward is irreversibly deformed radially outwardly by the fixing screw 70 (step V) or is reversibly compressed radially outward (step VI, see above). According to an alternative, the projection extending in the axial direction is displaced radially outward, or the fixing screw 70 is screwed into the undersized thread.
    [0058] Before the fixing screw 70 is screwed into the internal thread 16 of the retaining element 30, in step VII there is a new axial positioning of the spring loaded ring 54 on the fixing screw 70 which is screwed into it. The ring 54 is thus axially displaced, so that the thread of the fixing screw 70 can extend into the internal thread 16 of the retaining element 10. By screwing the fixing screw 70 into the retaining element 10, the first component B1 is attached to the second component B2. It is also preferred to secure the fixing screw 70 to the first component B1 with the aid of a screw nut. LIST OF REFERENCE NUMBERS: 10 Retention element. 12 Flange. 14 Cylindrical recess. 16.
