When the first element is functionally installed on the second element, the free end of the hook extends downwards in the vertical direction, and an upper side of the hook bears at least partially against an underside of the projection.

[0010] The core concept of the invention is therefore to provide the fastening device with a fixing element, a hook, and a hook receptacle. Thus, when the hook is arranged in the hook receptacle and the first element is thus fastened to the second element, the fixing element can easily fix the first element to the second element. The projection allows the hook to be pivoted into the hook receptacle, but cannot be inserted into and / or removed from the hook receptacle by sliding it in the first direction.

[0011] The fastening device according to the invention thus enables an assembly-friendly fastening of a first element to a second element.

[0012] In a preferred embodiment of the fastening device according to the invention, the hook receptacle is a suspension bar.

[0013] The hanging bar can extend horizontally.

[0014] The hanging bar can also extend vertically or diagonally.

[0015] In an exemplary embodiment, the fastening device according to the invention comprises at least two hooks or the hook is designed in the form of a first suspension bar.

[0016] The at least two hooks or the hanging rail are / are both hooked into the same second hanging rail for fastening the first element to the second element, for example.

[0017] At least one hook can be a hook rail.

[0018] The projection can be elastically deformable in such a way that it allows the hook to be inserted into the hook receptacle and / or prevents the hook from being removed from the hook receptacle up to a defined force.

[0019] The projection is provided, for example, above the hook holder.

[0020] The ledge can be a ramp.

[0021] In a preferred embodiment of the fastening device according to the invention, the hook is fixed in the hook receptacle by means of the fixing element.

[0022] In an exemplary embodiment of the fastening device according to the invention, the hook is clamped in the hook receptacle by means of the fixing element.

[0023] In particular, the hook in the hook receptacle can be tensioned into the hook receptacle by the fixing element, in particular counter to the first direction.

[0024] In a preferred embodiment of the fastening device according to the invention, the fixing element is arranged opposite the hook receptacle and the hook in a functionally correct installed state of the fastening device on a motor vehicle.

[0025] In an exemplary embodiment of the fastening device according to the invention, the fixing element is arranged at a distance from the hook receptacle, i.e. offset from it, in a functionally correct installed state of the fastening device on the motor vehicle.

[0026] In a functionally correct installation state of the fastening device on the motor vehicle, the fixing element is arranged, for example, at a distance from the hook receptacle, laterally next to the hook receptacle and the hook.

[0027] The fixing element can also be arranged above or below the hook receptacle and the hook in a functionally installed state of the fastening device on the motor vehicle.

[0028] The fixing element can be a detachable or non-detachable connecting element.

[0029] The fixing element is, for example, a screw, a screw nut, a bayonet element, a welding element or a rivet element.

[0030] Furthermore, the invention relates to an assembly of a motor vehicle, comprising a first element, a second element and a fastening device as described above.

[0031] The hook can be formed on the first element. The hook receptacle is formed, for example, on the second element.

[0032] Alternatively, the hook may be formed on the second element and the hook receptacle may be formed on the first element.

[0033] The first element can thus be fixed to the second element by means of the fastening device.

[0034] In an exemplary embodiment of the assembly according to the invention, the first element comprises at least one first through-bore and the second element comprises at least one blind hole with an internal thread or at least one second through-bore with an internal thread.

[0035] The blind hole or the second through hole may include an internal thread.

[0036] The fixing element, in particular the screw, can be arranged in the through-hole and fix the first element to the second element.

[0037] In particular, the fixing element can be screwed into an internal thread of the second element.

[0038] If the hook is located in the hook receptacle, the first through-hole is arranged, for example, offset from the blind hole or the second through-hole, in particular vertically above the blind hole or the second through-hole. By inserting the fixing element into the first through-hole and screwing the fixing element into the internal thread of the blind hole or the second through-hole, the first element, in particular the hook, is clamped in the hook receptacle. The intensity of the preload can be influenced by the size of the offset between the first through-hole and the blind hole or the second through-hole. In particular, the greater the offset between the first through-hole and the blind hole or the second through-hole, the greater the preload.

[0039] The first element can encompass the second element, particularly in an area around the first through-hole and the second through-hole or the blind hole. This allows the first through-hole and the second through-hole or the blind hole to be centered relative to one another.

[0040] The second element can also encompass the first element, in particular in an area around the first through-bore and the second through-bore or the blind hole, whereby the first through-bore and the second through-bore or the blind hole can be centered relative to one another.

[0041] In a preferred embodiment of the assembly according to the invention, the first element is a loudspeaker cabinet.

[0042] The second element can be a body component or a component attached to the body, in particular a door of a motor vehicle, in particular a door carrier.

[0043] The door support, for example, is a lightweight door support.

[0044] Alternatively, the second element can be a body or a body-mounted component.

[0045] The invention is explained in more detail below using an exemplary embodiment illustrated in the drawing. It shows: Fig. 1 a sectional view through an assembly according to the invention.

[0046] The Fig. Figure 1 shows a sectional view through an assembly of a motor vehicle according to the invention. The assembly comprises a first element 2, a second element 4, and a fixing element 6. The fixing element 6 is a screw.

[0047] The first element 2 is a loudspeaker enclosure. The second element 4 is a door support for a motor vehicle door.

[0048] The first element 2 comprises a hook 8 on its side facing the second element 4. The hook 8 extends downwards in the vertical direction in a functionally correct installed state of the first element 2 on the second element 4.

[0049] The second element 4 has a hook receptacle 10. The hook receptacle 10 is a recess that corresponds to the shape of the hook 8. The hook 8 can thus be arranged in the hook receptacle 10 for fastening the first element 2 to the second element 4.

[0050] A projection 12 is provided at an upper end of the hook receptacle 10. The projection 12 extends toward the first element 2 and forms a kind of ramp. The hook 8 can thus be inserted into the hook receptacle 10 by a pivoting movement.

[0051] If the hook 8 is arranged in the hook receptacle 10, as shown in the figure, the hook 8 rests with its upper side at least partially against a lower side of the projection 12. This prevents an unintentional upward displacement of the hook in the vertical direction, ie, a removal of the hook 8 from the hook receptacle 10.

[0052] The first element 2 has a through-bore 14. In a functionally installed state of the first element 2, the through-bore 14 is formed on the second element 4 vertically below the hook 8.

[0053] The second element 4 comprises a blind hole 16 with an internal thread.

[0054] To position the first element 2 relative to the second element 4, the first element 2 comprises, on a side facing the second element 4, a recess 18 formed at least partially around the through-bore 14. The second element 4 has a region 20 corresponding to the recess 18, which comprises at least parts of the blind hole 16. By arranging the region 20 of the second element 4 corresponding to the recess 18, the first element 2 can thus be positioned relative to the second element 4.

[0055] To fix the first element 2 to the second element 4, the fixing element 6 is screwed into the internal thread of the blind hole 16. The fixing element 6 is first inserted into the through-bore 14 of the first element 2.

[0056] In order to prevent the hook 8 from coming loose from the hook receptacle 10, the hook 8 is clamped in the hook receptacle 10 by screwing the fixing element 6 into the blind hole 16.

[0057] For this purpose, the through-hole 14 is positioned slightly above the blind hole 16 in the vertical direction when the hook 8 is arranged in the hook receptacle 10 and the fixing element 6 is not screwed into the blind hole 16. By screwing the fixing element 6 into the blind hole 16, the through-hole 14 is pulled vertically to the same height as the blind hole 16, so that the through-hole 14 is aligned with the blind hole 16. The hook 8 is thus clamped in the hook receptacle 10.

[0058] The first element 2 encompasses the second element 4 in an area around the through hole 14 and the blind hole 16, thereby ensuring correct positioning of the first element 2 relative to the second element 4.

[0059] It is also conceivable to design the assembly without tension, ie such that the through hole 14, when the hook 8 is located in the hook receptacle 10, is arranged in the vertical direction at the same height as the blind hole 16, i.e. is aligned with it, regardless of whether the fixing element 6 is arranged in the blind hole 16, in particular screwed in or not.
