Description

[0001] The invention relates to a fastening arrangement of a lock on a component of a vehicle, in particular a motor vehicle, according to the preamble of claim 1.

[0002] DE 10 2009 037 037 B4 discloses a reduction device for a vehicle door, comprising a rotary latch cooperating with a locking pawl, which, in a closed position in which a locking element can be fixed by the rotary latch when the vehicle door is closed, can be locked by the locking pawl in a locking position. DE 10 2018 217 967 A1 discloses a lock for a vehicle tailgate, comprising at least a number of lock fixings for attachment to a vehicle structure and / or a vehicle component, wherein each lock fixing includes a decoupling element for decoupling the lock from the vehicle structure or the vehicle component. Furthermore, DE 10 2011 055 506 A1 discloses a fastening device for a motor vehicle tailgate.

[0003] The object of the present invention is to create a fastening arrangement for a lock on a component of a vehicle, such that a particularly advantageous noise behavior of the fastening arrangement and thus of the vehicle as a whole can be achieved.

[0004] This problem is solved according to the invention by a fastening arrangement having the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

[0005] The invention relates to a fastening arrangement for a lock, also referred to as a tailgate lock or trunk lock, on a component of a vehicle, preferably a motor vehicle, that is formed separately from the lock. This means that the vehicle, whose interior, also referred to as the passenger compartment, passenger space, or cabin, is formed by a body of the vehicle, for example, a self-supporting body, comprises the component and the lock in its fully manufactured state. Furthermore, the vehicle has a tailgate that is pivotably mounted on the body between a closed position and at least one open position relative to the vehicle body, and which can, for example, be a component of the fastening arrangement. The tailgate is located at the rear of the body and the vehicle.The tailgate is also referred to as a storage compartment lid, trunk lid, or boot lid. For example, the vehicle body has a rear opening, also known as a storage compartment opening, located at the rear of the vehicle. This opening, viewed from the outside, opens at one end into the surrounding area of ​​the vehicle and at the other into a rear compartment, preferably a boot or luggage compartment, in which goods such as luggage can be transported. When closed, the tailgate closes at least part of the opening. More specifically, when closed, the tailgate closes the entire opening, which is also simply referred to as the opening.In the open position, the tailgate exposes at least a portion of the vehicle body opening, allowing, for example, the aforementioned cargo to be placed in or removed from the space via this exposed area. In particular, the tailgate is pivotally mounted to the vehicle body about, and especially precisely, a pivot axis relative to the vehicle body. Preferably, this pivot axis runs in the transverse direction of the vehicle, i.e., parallel to the vehicle's transverse direction.

[0006] The lock holds the tailgate in the closed position relative to the vehicle body. In other words, if the tailgate is in the closed position and the lock is engaged, the lock holds the tailgate in the closed position relative to the vehicle body, thus preventing unwanted movement from the closed to the open position.

[0007] In this mounting arrangement, the lock is attached to the component. The component is, for example, a part of the tailgate, so that the component, and therefore the lock, can pivot along with the tailgate around the pivot axis relative to the body between the closed and open positions. Furthermore, it is conceivable that the component is a part of the body, so that the tailgate can pivot around the pivot axis relative to the body, relative to the component, and relative to the lock between the closed and open positions.

[0008] The lock is associated with a first locking element, which is designed, for example, as a locking bar, also known as a locking bolt. If the component is part of the tailgate, such that the lock and the component can pivot with the tailgate relative to the body, then the first locking element is attached to the body. This allows the tailgate, the component, and the lock to pivot around the pivot axis relative to the body and relative to the first locking element, particularly between the closed and open positions. However, if the component is a part of the body, i.e., a body component, then the first locking element is attached to the tailgate. This allows the tailgate and the first locking element to pivot around the pivot axis between the open and closed positions relative to the body, the component, and the lock.

[0009] The lock, for example, has a second locking element, which is designed, for instance, as a locking latch, particularly a rotary latch, or more specifically, a fork latch. When the tailgate is in the closed position and the lock is in its locked state, the locking elements interact, particularly in a positive-locking manner, thereby holding the tailgate in the closed position relative to the vehicle body, i.e., securing it. To open the tailgate, i.e., to move it from the closed to the open position, the lock is unlocked, thus being moved from its locked to an unlocked state. For this, the second locking element is moved relative to the first locking element, thereby releasing the positive-locking interaction between the locking elements.As a result, the tailgate can be opened, i.e., pivoted from the closed position to the open position relative to the body.

[0010] In the fastening arrangement, the lock is supported on the component by at least one decoupling element, which is designed separately from the lock and the component and is elastically deformable, in particular rubber-elastic, in such a way that the decoupling element rests on the lock on one side, in particular directly, and on the component separately from the lock on the other, in particular directly, and is thus supported. In particular, in the fastening arrangement, the lock is supported on the component by the decoupling element in such a way that the decoupling element deforms elastically, in particular rubber-elastically, at least in one area of ​​the decoupling element during relative movements between the lock and the component.This means, for example, that the lock is held on the component in a way that is at least essentially vibration-isolated, so that, for example, excessive, unwanted transmission of vibrations from the lock to the component can be avoided.

[0011] In order to achieve a particularly advantageous noise behavior of the fastening arrangement and consequently of the vehicle as a whole, the invention provides that the decoupling element has a first stiffness, in particular with regard to elastic deformability, along a first direction extending in a first plane, which is preferably straight and thus runs along a first straight line, wherein the decoupling element has a second stiffness, different from the first stiffness, in particular with regard to its elastic, in particular rubber-elastic, deformability, along a second direction extending in a second plane perpendicular to the first plane and perpendicular to the first direction, which is preferably straight and thus runs along a second straight line perpendicular to the first straight line.This means that along the first direction, a first force must be applied, i.e., exerted, on the decoupling element, in particular on a point of the decoupling element, in order to deform the decoupling element elastically, in particular rubber-elastically, along the first direction such that a first sub-area of ​​the decoupling element moves a distance relative to a second sub-area of ​​the decoupling element, and that along the second direction, a second force, different from the first force, must be applied, i.e., exerted, on the decoupling element, in particular on the aforementioned point of the decoupling element, in order to deform the decoupling element elastically along the second direction such that the first sub-area of ​​the first element moves the same distance relative to the second sub-area of ​​the decoupling element.The same principle can be applied to the lock, for example: Since the decoupling element has the aforementioned, different stiffnesses, a first force must be applied, i.e., exerted, on the lock, in particular on a point of the lock, along the first direction, to move the lock by a distance relative to the component by elastic, in particular rubber-elastic, deformation of the decoupling element along the first direction, and a second force, different from the first force, must be applied, i.e., exerted, on the lock, in particular on the aforementioned point of the lock, along the second direction by the same distance relative to the component by elastic, in particular rubber-elastic, deformation of the decoupling element.Since the decoupling element exhibits these differing stiffnesses, it displays a direction-dependent stiffness, enabling particularly advantageous decoupling, especially vibration decoupling, of the lock from the component. On the one hand, this allows, for example, the lock to secure the tailgate in the closed position relative to the body, thus preventing excessive, undesirable relative movements between the tailgate and the body, particularly around the pivot axis. On the other hand, excessive transmission of vibrations between the component and the lock can be avoided, thereby preventing excessive excitation of the body and, consequently, excessive noise audibly perceptible to occupants.In particular, noises such as thumping and humming, which are perceived as extremely unpleasant by people inside the building, can be avoided, resulting in a particularly advantageous noise profile.

[0012] The characteristic of differing stiffnesses means that the decoupling element is less stiff, i.e., softer, along one direction than along the other. This allows the decoupling element to deform more elastically under the same force in one direction than in the other. Thus, the decoupling element exhibits a deliberately controlled degree of softness along one direction, which is greater than the degree of softness along the other direction.

[0013] In order to achieve a particularly advantageous noise behavior, in one embodiment of the invention it is provided that the first plane runs perpendicular to the pivot axis about which the tailgate is pivotably held on the body relative to the body, at least in the closed position of the tailgate.

[0014] Another embodiment is characterized in that the tailgate is mounted on the body so as to be pivotable along a path of movement relative to the body, particularly about the pivot axis. In particular, the path of movement is arc-shaped, especially circular, so that, for example, the path of movement is a circular path.

[0015] In achieving particularly advantageous noise characteristics, it has proven especially beneficial if the path of motion runs in the first plane.

[0016] In a further, particularly advantageous embodiment of the invention, the first direction is tangent to the path of movement and coincides with at least part of it. This allows for particularly advantageous noise characteristics, as excessive excitations of the bodywork caused or potentially caused by the tailgate via the lock and the component can be avoided.

[0017] To effectively avoid unwanted noise and thus achieve particularly advantageous noise characteristics, a further embodiment of the invention provides that the second stiffness is greater than the first stiffness, so that, for example, the decoupling element is softer or less soft along the first direction than along the second direction. In particular, the first direction is a closing direction of the tailgate, which can be moved from the open position to the closed position, or the closing direction coincides with the first direction, so that the decoupling element is preferably softer in or along the closing direction of the tailgate than along the second direction.

[0018] In a further, particularly advantageous embodiment of the invention, the decoupling element has a cross-section extending in the first plane. In other words, the cross-section is a cross-section extending in a cross-sectional plane, where the cross-sectional plane coincides with the first plane.

[0019] In order to be able to adjust the stiffness and thus the respective softness of the decoupling element along the directions in a targeted and required manner, a further embodiment of the invention provides that the cross-section has at least one hollow chamber which is preferably completely enclosed along its circumferential direction by the decoupling element and thus by a material from which the decoupling element is formed. Thus, the cross-section is preferably designed as a closed hollow cross-section.

[0020] Preferably, a gas, especially air, is contained in the hollow chamber, and in particular exclusively in it.

[0021] It is conceivable that the hollow chamber has at least one opening, particularly laterally, and is thus open, especially laterally. The hollow chamber is formed, for example, by at least one inserted pin or slide in a tool by which the decoupling element is manufactured. For example, the decoupling element is manufactured by an injection molding process, i.e., by injection molding, wherein the injection molding process is carried out by means of the tool. Thus, the tool is preferably an injection mold. In the injection molding process, for example, a melt of an elastomer, from which the decoupling element is manufactured, is injected into the tool, whereupon the elastomer cross-links and solidifies in the tool. Then, for example, the pin or slide is pulled out, and the tool is opened. The decoupling element can then be removed from the tool.

[0022] It is also conceivable to divide the tool into alternating projections, such that a first section or wall of the hollow chamber is formed first, followed by a second section or wall opposite the first section or wall. The gas contained in the hollow chamber, in particular air, is ambient air, especially since the hollow chamber is open, particularly laterally and / or in at least one direction.

[0023] In a further, particularly advantageous embodiment of the invention, the cross-section has at least or exactly two hollow chambers, namely the at least one hollow chamber as the first hollow chamber and a second hollow chamber. The preceding and following descriptions relating to the at least one hollow chamber can readily be applied to the second hollow chamber and vice versa.

[0024] If the cross-section has at least two or exactly two hollow chambers, the stiffness can be adjusted in a particularly targeted and thus required manner, so that excessive excitations and thus excessive noise perceptible to people in the interior can be avoided.

[0025] Preferably, the hollow chambers are separated from each other, in particular completely, by a web of the decoupling element arranged between the hollow chambers, the web being made in particular of the aforementioned material. In particular, the web partially and directly delimits each of the hollow chambers. This allows the stiffness to be adjusted with particular precision.

[0026] Another embodiment is characterized in that the cross-section has two outer surfaces spaced apart from each other along the first direction and pointing away from each other along the first direction, namely a first outer surface extending in a first plane and a second outer surface extending in a second plane. The planes of extension are parallel to each other and perpendicular to the first plane. Furthermore, the planes of extension are spaced apart from each other along the first direction. This allows the stiffness of the decoupling element to be adjusted particularly advantageously, thus avoiding excessive noise and achieving particularly favorable noise characteristics.

[0027] In order to achieve particularly advantageous noise characteristics, it has proven especially beneficial if the respective extension plane runs perpendicular to the second plane.

[0028] In a further, particularly advantageous embodiment of the invention, the respective plane of extension is inclined to a direction of movement in which the tailgate can be pivoted from the closed position towards the open position relative to the body, in particular about the pivot axis. In particular, the direction of movement runs in the first plane. For example, the direction of movement is tangent to the aforementioned path of movement. Furthermore, it is conceivable that the direction of movement coincides at least partially with the path of movement. Most preferably, the direction of movement is a direction in which the tailgate, initially in the closed position, moves, in particular precisely at the moment when the tailgate begins its movement from the closed position towards the open position.In particular, it is conceivable that the direction of movement runs in the first plane and is parallel to the vehicle's transverse direction, or that the direction of movement runs in the first plane and is oblique to the vehicle's transverse direction, with the direction of movement in the longitudinal direction of the vehicle pointing rearward. Since the respective extension plane is oblique to the direction of movement, the first stiffness can be advantageously adjusted, thereby avoiding excessive noise. It is particularly intended that the direction of movement coincides with the first direction.

[0029] In order to avoid excessive excitation of the bodywork and thus excessive noise perceptible to persons in the interior and perceived as unpleasant, and consequently to achieve particularly advantageous noise behavior, it is provided in a further embodiment of the invention that a respective first end of the respective outer surface, facing the component and, for example, at least in the closing position in the vehicle's vertical direction, being lower, is offset in the direction of movement relative to a respective second end of the respective outer surface, opposite the respective first plane and the component and, for example, at least in the closing position in the vehicle's vertical direction, being upper.This allows the decoupling element to counteract, for example, a rotational movement of the tailgate relative to the body and around the pivot axis, and which may point in the direction of the open position, whereby this rotational movement results, for example, from pulling on the tailgate lock, particularly in the direction of the open position, while the tailgate is in the closed position and, for example, the lock is engaged, i.e., in its locked state.

[0030] Another embodiment is characterized in that the cross-section has two outer surfaces spaced apart from each other along the first direction and pointing away from each other along the first direction, namely an arcuate first outer surface and an arcuate second outer surface. This allows the first stiffness to be adjusted particularly effectively and advantageously, thus achieving particularly favorable noise characteristics.

[0031] In achieving particularly advantageous noise characteristics, it has proven especially beneficial if the outer surfaces are curved towards each other.

[0032] Finally, it has proven particularly advantageous if the decoupling element is made of an elastomer.

[0033] Furthermore, it would be conceivable for the decoupling element to be made of a metallic material, in particular steel, and especially spring steel. For example, the decoupling element could be designed as a leaf spring whose opposing broad sides extend in their respective broad-side planes, with narrow sides of the leaf spring arranged between the broad sides. The broad-side planes preferably run parallel to each other and are spaced apart. The narrow sides extend, for example, in their respective narrow-side planes. Preferably, the narrow-side planes run parallel to each other and are spaced apart.Preferably, the leaf spring, which is preferably arranged between the lock and the component, is oriented relative to the lock and the component such that one of its narrow sides faces the component and the other narrow side faces the lock, so that, for example, the broad sides, and thus the broad-side planes, are spaced apart from each other along the first direction or along the second direction. Furthermore, it is conceivable that the leaf spring, viewed in a third plane, has a meandering shape, with the third plane preferably being perpendicular to the first plane and perpendicular to the second plane.

[0034] Overall, it is evident that the invention allows for targeted control, i.e., adjustment, of which direction the decoupling element is more elastically deformable, i.e., more easily and thus softer, than along the other direction. In other words, the invention offers a way to adjust or control the stiffness and thus the degree of deformation of the decoupling element along the directions. This allows for the achievement of particularly advantageous noise characteristics.

[0035] Also disclosed is a vehicle which has a fastening arrangement according to the invention.

[0036] Further details of the invention will become apparent from the following description of preferred embodiments with the accompanying drawings. These show: Fig. 1. Partially a schematic perspective view of a retaining arrangement of a tailgate on a vehicle body, wherein the retaining arrangement includes a fastening arrangement of a lock on a component of the vehicle; Fig. 2 a schematic side view of the tailgate in its closed position; Fig. 3 a schematic and cutaway side view of the fastening arrangement according to a first embodiment, Fig. 4 a schematic perspective view of the fastening arrangement according to a second embodiment; Fig. 5. Partially a schematic side view of the fastening arrangement according to the second embodiment; Fig. 6. A schematic and cutaway perspective view of the fastening arrangement according to a third embodiment; Fig. 7. Partially a schematic side view of the fastening arrangement according to the first embodiment; Fig. 8. Partially a schematic side view of the fastening arrangement according to the first embodiment; Fig. 9 a schematic side view of the fastening arrangement according to the second embodiment; and Fig. 10. Partially a schematic side view of the fastening arrangement according to the second embodiment.

[0037] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0038] Fig. Figure 1 shows a partial schematic perspective view of a retaining arrangement 1 for a tailgate 2 on a vehicle body 3, preferably designed as a self-supporting body, whose interior, also referred to as passenger compartment, passenger cell, or cabin, is formed, i.e., bounded, by the body 3. During a journey, persons such as the driver of the vehicle can be present in the interior. Preferably, the vehicle is a motor vehicle, in particular a car, and most preferably a passenger car. The body 3 has a rear storage compartment 4, which is also referred to as a trunk or luggage compartment. Cargo, such as luggage, can be arranged in the storage compartment 4 and subsequently transported by the vehicle. Fig. A body component 5 of the body 3 is partially visible. The body 3 has a rear-facing opening 6, also referred to as a body opening, which is located at the rear of the body 3 and the vehicle and is designed as a through-opening. This opening, viewed solely from the perspective of the body 3, particularly in the longitudinal direction of the vehicle, opens at one end into the storage compartment 4 and at the other end into the surrounding area of ​​the body 3, particularly the vehicle as a whole. The opening 6 is at least partially, and in particular at least predominantly, and thus at least more than halfway or completely, bounded downwards by the body component 5.For example, in the fully manufactured state of the vehicle, a seal, in particular made of rubber, is held on the body component 5, by means of which the tailgate 2 is sealed against the body 3 in its closed position, thereby sealing the opening 6.

[0039] The tailgate 2 is pivoted relative to the body 3 around a pivot axis not visible in the figures, between a Fig. The tailgate 2 is pivotably held on the body 3 in the closed position S shown and at least one open position, such that the tailgate 2 can pivot relative to the body 3 about the pivot axis between the closed position S and the open position, while the tailgate 2 is and remains held on the body 3. The closed position S of the tailgate 2 is also shown in Fig. Figure 2 shows that in the closed position S, at least part of the opening 6 is closed by the tailgate 2. In the open position, the tailgate 2 releases at least this part, allowing objects, and thus the aforementioned transported goods, to be moved through the released area. This allows the objects to be placed in or removed from the storage compartment 4 and moved into the surrounding area.

[0040] The retaining arrangement 1 has a fastening arrangement 7 for a lock 8, also referred to as a tailgate lock, on the body component 5. The body component 5 is a component to which the lock 8 is attached by the fastening arrangement 7. Fig. Figure 3 shows a first embodiment of the fastening arrangement 7. Fig. 4 and Fig. 5 a second embodiment of the fastening arrangement 7. Fig. Figure 6 shows a third embodiment of the fastening arrangement 7, Fig. 7 and Fig. Figure 8 shows the first embodiment of the fastening arrangement 7, and Fig. 9 and Fig. Figure 10 shows the second embodiment of the fastening arrangement 7. In these embodiments, the component mentioned is the body component 5 of the body 3. Thus, in both the first and second embodiments, the tailgate 2 can be pivoted about the pivot axis relative to the body component 5, relative to the body 3, and relative to the lock 8 between the closed position S and the open position.

[0041] A first locking element 9, designed in this case as a locking bar, is attached to the tailgate 2. This first locking element 9 can pivot with the tailgate 2 around the pivot axis relative to the body 3, and thus relative to the body component 5 and relative to the lock 8, between the closed position S and the open position. The lock 8 has a second locking element, which is designed, for example, as a latch, in particular as a rotary latch. When the tailgate 2 is in its closed position S, while the lock 8 is in its locked state, the locking elements interact, in particular in a positive-locking manner, thereby holding the tailgate 2 in the closed position S relative to the body 3 and thus securing it against movement from the closed position S to the open position. Thus, the lock 8 holds the tailgate 2 in the closed position S relative to the body 3.

[0042] As from Fig. As can be seen from Figures 3 to 6, in the fastening arrangement 7 the lock 8 is supported on the body component 5 by means of decoupling elements 10 that are elastically, in particular rubber-elastic, deformable separately from the lock 8 and separately from the body component 5, in this case such that the respective decoupling element 10 deforms elastically, in particular rubber-elastically, at least in one area during relative movements between the lock 8 and the component, i.e. the body component 5. This is particularly evident from... Fig. 3 and Fig. 4 can be seen that the respective decoupling element 10 is directly attached to the lock 8 on the one hand and directly to the body component 5 on the other.

[0043] The decoupling elements 10 can be formed separately from one another. Furthermore, it would be conceivable that the decoupling elements 10 are formed in one piece, i.e., as a single unit, so that the decoupling elements 10 are formed from a single piece and thus constitute a monoblock body formed from a single piece and integrally manufactured.

[0044] In the embodiments, the respective decoupling element 10 is formed from an elastomer and is thus designed as an elastomeric body.

[0045] If the tailgate 2 is in the closed position S, and is held in this position by the lock 8, meaning the lock elements interact, particularly in a positive-locking manner, slight movements about the pivot axis and relative to the body 3 can occur during and as a result of the vehicle's movement, especially forward movement, causing vibrations of the tailgate 2. If no appropriate countermeasure is taken, vibrations of the body 3, also referred to as body vibrations, can be transmitted to the tailgate 2. The tailgate 2, also simply called the flap, then vibrates as a large diaphragm at the end of the body 3, which is designed as or forms a large cavity, causing a column of air within the cavity to vibrate at a low frequency.Body vibrations, also known as body vibrations, can originate from the vehicle's drive system or chassis and / or be caused by wind resistance. This can lead to undesirable noises that can be perceived by occupants as an unpleasant thumping and / or humming sound. To prevent this and thus achieve particularly favorable noise characteristics for the mounting arrangement 7 and consequently for the vehicle as a whole, each decoupling element 10, and thus the decoupling device formed by the decoupling elements 10, exhibits a first stiffness along a first direction extending in a first plane and a second stiffness along a second direction extending perpendicular to the first plane.

[0046] Fig. Figure 3 shows the lock 8 and the decoupling elements 10 in their installed position, in which the lock 8 and the decoupling elements 10 are located in the fully assembled state of the vehicle. The first direction is illustrated by a double arrow 11, with the first plane corresponding to the image plane of Fig. 3 coincides. The second direction is illustrated by a double arrow 12, where the second direction, and thus the second plane, is perpendicular to the image plane of Fig. 3. Thus, in this case, the first direction runs in the image plane of Fig. 3. In this case, the second plane, and thus the second direction, runs parallel to the vehicle's transverse direction, while the vehicle's longitudinal direction lies in the first plane. Furthermore, the first plane runs perpendicular to the pivot axis. The first plane runs perpendicular to the pivot axis at least in the closed position S and, in this case, also in the open position of the tailgate 2.

[0047] In Fig. Figure 2 shows a movement path B along which the tailgate 2 can be moved relative to the body 3 between the open position and the closed position S. This can be seen from... Fig. 2. The motion path B is circular and thus follows an imaginary circle, the center of which may, for example, lie on the pivot axis. The motion path B runs in the first plane. The first direction is straight and thus follows a first straight line, and the second direction is straight and thus follows a second straight line. In the embodiments, the first direction is tangent to the motion path B.

[0048] Out of Fig. Figures 3 to 6 show that each decoupling element 10 has a cross-section Q extending along the first plane. In both the first and second embodiments, the cross-section Q has, in particular, two hollow chambers: a first hollow chamber H1 and a second hollow chamber H2. Each hollow chamber H1, H2 is completely enclosed and surrounded along its respective circumferential direction, which extends along the first plane and, for example, around the second direction, by the decoupling element 10 and thus by the material from which the decoupling element 10 is formed. In these embodiments, the material is the aforementioned elastomer from which the decoupling element is formed.

[0049] It is also apparent that the respective hollow chambers H1 and H2 of the respective cross-section Q are, in particular completely, separated from one another by a web ST of the respective decoupling element 10 arranged between the respective hollow chambers H1 and H2, wherein the respective web ST partially and directly delimits the respective hollow chamber H1 and H2 of the respective cross-section Q. Furthermore, in the embodiments, for example, it is provided that the respective decoupling element 10 is formed in one piece, i.e., as a single unit and thus made from a single piece.This means that the respective decoupling element 10 is not composed of separately formed and connected parts, but rather the respective decoupling element 10 is formed from a single piece and thus by a one-piece body, i.e. formed from a single piece and thus integrally manufactured and thus formed from a monoblock.

[0050] The respective hollow chamber H1, H2 of the respective cross-section Q opens, in the present case, when considering only the respective decoupling element 10, along the second direction to a respective environment of the decoupling element 10, so that in the present case the respective hollow chamber H1, H2 is unlimited and thus open along the second direction, namely when considering only the respective decoupling element 10.

[0051] How particularly good looks Fig. As can be seen in Figure 5, in both the first and second embodiments, the respective cross-section Q has two outer surfaces spaced apart from each other along the first direction and pointing away from each other along the first direction, namely a first outer surface A1 extending in a first extension plane and a second outer surface A2 extending in a second extension plane. The extension planes run parallel or obliquely to the second plane. In particular, the extension planes run parallel to the second direction.

[0052] In Fig. Figure 5 illustrates a direction of movement by arrow 13 in which the tailgate 2 can pivot from the closed position S towards the open position relative to the body 3 about the pivot axis. In this case, the direction of movement illustrated by arrow 13 is a direction in which the tailgate 2, initially in the closed position S, moves about the pivot axis and relative to the body 3 from the closed position S towards the open position, specifically at or at a point in time when the tailgate 2, initially in the closed position S, begins its movement from the closed position S towards the open position, i.e., begins to open and thus moves from the closed position S towards the open position. In this case, the direction of movement is tangent to the path of movement B, and in this case, the direction of movement coincides with the first direction. This is evident from Fig. 5 is that each of the respective outer surfaces A1, A2, which faces the body component 5 and is therefore, in this case, the lower end in the vehicle's vertical direction, is offset in the direction of movement relative to a respective second end E2 of the respective outer surface A1, A2, which is opposite the respective first end E1 and the body component 5 and, in this case, the upper end in the vehicle's vertical direction. Thus, the respective decoupling element 10, through its respective elastic deformability or deformation, counteracts such a rotational movement of the tailgate 2, which, during the rotational movement, moves it a short distance in the direction of movement relative to the body 3, while the tailgate 2 is in the closed position S and is held in the closed position S by means of the lock 8.Such a rotational movement occurs, for example, when, while the tailgate 2 is in the closed position S and the lock 8 is in its locked state (thus holding the tailgate 2 in the closed position S), the tailgate 2 is pulled towards the open position O, for example by a person. The lock 8 prevents the tailgate 2 from opening, but the respective decoupling element 10, due to its elastic deformability, allows the aforementioned rotational movement. The varying stiffness of the decoupling element 10 helps to prevent excessive noise.

[0053] Out of Fig. Figure 6 shows that in the third embodiment of the fastening arrangement 7, the respective decoupling element 10 does not have a hollow cross-section, but a solid cross-section. Furthermore, the outer surfaces A1 and A2 of the respective decoupling element 10 are arcuate and thus curved, in this case such that the respective outer surfaces A1 and A2 of the respective decoupling element 10 curve towards each other.

[0054] It is evident that in the Fig. 4 and Fig. In the second embodiment shown in section 5, the decoupling elements 10, particularly when considered together or as a whole, are designed or arranged in a parallelogram-like or parallelogram-shaped manner and / or are arranged or designed in the form of a parallelogram. This is also the case in the embodiment shown in Fig. 9 and Fig. The second embodiment shown in 10 is provided. In the embodiment shown in Fig. 3 first embodiment shown and in the Fig. In the third embodiment shown in 6, the decoupling elements 10, particularly when considered together or as a whole, are trapezoidal or trapezoidal in shape or arranged in a trapezoidal form. This is also the case in the embodiment shown in Fig. 7 and Fig. 8 first embodiment shown.

[0055] Fig. Figure 7 shows the fastening arrangement 7 according to the first embodiment in an unloaded state of the decoupling element 10, while Fig.Figure 8 shows the fastening arrangement 7 in a loaded state of the decoupling element 10. It can be seen that the trapezoidal shape or arrangement of the decoupling element 10 is particularly effective in preventing or counteracting any tilting of the lock 8, which occurs, for example, when the lock is rotated under load from a desired target or rest position. In particular, the trapezoidal shape or arrangement of the decoupling element 10 counteracts an unfavorable tilting of the lock 8 away from a closing tangent.
