Description

Title of the invention: Built-in device for a motor vehicle and system

[0001] The present invention relates to a built-in device for a motor vehicle. The invention further relates to a system comprising such a built-in device and a mounting means intended to be mounted in a mounting space, in particular a mounting space for a built-in device intended for front mounting, of a motor vehicle.

[0002] Such built-in devices are now used in almost all motor vehicles for mounting, for example, a tachograph unit, also called a speedometer.

[0003] The dimensions of the built-in device are generally based on DIN ISO 7736:1985-04, which also specifies the mounting options for the built-in device in the vehicle's mounting space. Preferably, a lateral mounting of the built-in device in the vehicle's mounting space is proposed, in which the built-in device has a housing equipped with a retaining element. The retaining element engages in a corresponding recess in a mounting means within the vehicle's mounting space, which is used to mount the device in the vehicle's mounting space. The built-in device is thus locked and held in the vehicle's mounting space by the mounting means, preventing its removal.

[0004] The drawback of these prior art built-in devices is that the retaining element mounted on the housing is damaged when the built-in device is removed from the vehicle's mounting space, and the retaining means formed on the retaining element deforms uncontrollably. In fact, an extraction tool strikes the retaining means or slips under it, between the housing and the retaining means, and deforms it, making it difficult, or even impossible, to remove the built-in device from the mounting space. The retaining means deforms to such an extent that the built-in device becomes jammed with the mounting means in the mounting space.

[0005] Furthermore, problems arise when the built-in appliance is reinstalled. The dimensions and tolerances of the built-in appliance, particularly of the retaining element mounted on the housing, are no longer met due to deformation of the retaining element. The built-in appliance cannot can be inserted with difficulty into the mounting space of the motor vehicle or into the mounting means disposed in the mounting space.

[0006] The present invention aims to provide a built-in device of the aforementioned type, equipped with a housing and a retaining element that allows for safe and reliable mounting or removal of the built-in device without damaging or deforming the retaining element or the retaining means formed on the retaining element. The invention further aims to provide a system comprising such a built-in device and a mounting means intended for installation in a mounting space of a motor vehicle.

[0007] According to a first aspect of the present invention, a built-in device for a motor vehicle comprises a parallelepiped-shaped housing, the housing having, on an outer face, on two opposite sides of the housing, a respective retaining element. Each of the retaining elements respectively has a retaining means, the respective retaining means being securely connected to the housing in its longitudinal extension, at a first end disposed in the mounting direction in which the built-in device is installed in the motor vehicle. The respective retaining means is designed such that the built-in device can be held in the motor vehicle in the installed state by means of the two retaining means.The housing comprises, on its outer face, on two opposite sides of the housing, a recess, each with a bevel, the respective recess being parallel to the mounting direction and the respective retaining means. The respective recess is designed such that the respective retaining means, in its longitudinal extension, can be received in the respective recess perpendicular to the mounting direction, at a second end disposed in a direction opposite to the mounting direction, which is a free end, and can be guided onto the respective bevel.

[0008] A particular advantage of the built-in appliance according to the invention is the technical design of a recess having a bevel on two opposite outer faces of the housing. Thus, when removing the built-in appliance, the retaining means of the retaining element extending along the housing parallel to the recess can be received in the respective recess in its longitudinal extension and guided along the bevel formed on the recess. The retaining means is thus driven in a controlled manner into the corresponding recess during removal by means of an extraction tool. The retaining means is not deformed uncontrollably, which prevents the built-in appliance from catching and jamming when it is removed from the mounting space or from the mounting means located in the mounting space. The built-in appliance can therefore be correctly guided out of the mounting space during removal.The built-in appliance according to the invention can preferably be . a tachograph unit or more generally an on-board unit for a motor vehicle, in particular for a commercial vehicle.

[0009] According to an advantageous embodiment of the invention, the respective bevel formed on the housing has, perpendicular to the housing, in a direction opposite to the direction of assembly an angle a greater than 90°, preferably an angular range between 110° and 150°, the bevel preferably having an angle of 135°.

[0010] An advantage lies in the fact that the respective retaining means, in its longitudinal extension, is received in the respective recess perpendicular to the mounting direction, at the level of a second end disposed in a direction opposite to the mounting direction, which is a free end, and is guided on the respective bevel.

[0011] Thus, during disassembly using the extraction tool, the retaining means is not driven uncontrollably into the housing material, which would damage both the housing and the retaining means. Because the retaining means is received in the recess and its free end is guided along the bevel, the retaining means maintains its shape and does not easily deform during disassembly, as the pressure forces exerted on the retaining means by the extraction tool are transmitted to the bevel.

[0012] According to an advantageous embodiment of the invention, the respective retaining element has two retaining means, a first retaining means and a second retaining means being arranged parallel to each other.

[0013] One advantage lies in the fact that the built-in device provides a tight and secure fit within the vehicle's mounting space. This protects the built-in device from uncontrolled sliding within the mounting space, for example, in the event of an accident. Furthermore, the device is prevented from tipping into place within the mounting space after installation when the respective retaining element or the respective first and second retaining means engage with the mounting means positioned within the mounting space. Another advantage lies in the fact that the pressure forces exerted between the retaining element or the first and second retaining means, as well as the mounting means, are distributed evenly across the housing of the built-in device.

[0014] According to an advantageous embodiment of the invention, the respective retaining element is made of metal.

[0015] One advantage lies in the fact that a metal retaining element is robust against applied forces and is easily formed and bent. This is particularly advantageous when pressure forces are exerted on the retaining element during assembly or disassembly using the extraction tool. Furthermore, metal exhibits high material strength. Compared to an element of Plastic retainers, for example, exhibit slower fatigue and aging than metal retainers. Another advantage is that a metal retainer can be quickly and economically shaped into any desired form.

[0016] According to an advantageous embodiment of the invention, the retaining element is manufactured in the form of a cut and folded piece.

[0017] One advantage lies in the fact that the retaining element can be manufactured individually as a cut and bent component according to the specifications and requirements of the respective technical specifications. Another advantage lies in the fact that the cut and bent parts can be manufactured quickly, accurately, economically, and with energy savings. Furthermore, the cut and bent parts offer great flexibility in the shaping and design of the part to be produced and can be manufactured in large quantities.

[0018] According to an advantageous embodiment of the invention, the respective retaining means of the respective retaining element is designed to be elastically flexible in its longitudinal extension, perpendicular to the mounting direction.

[0019] One advantage lies in the fact that the retaining means can be elastically deformed to a small extent under the effect of applied forces, for example, under the effect of pressure forces exerted by the extraction tool. No deformation or change in the plastic shape of the retaining means occurs when pressure forces are exerted on the retaining means by the extraction tool. During elastic deformation, the retaining means returns to its initial state after the deformation, once the force exerted on the retaining means is removed. Another advantage is that the retaining means does not lose its shape under the effect of applied forces and retains its original shape. This ensures that the retaining means fulfills its function as a retaining element and that the built-in appliance, in the installed state, is securely clipped in place.

[0020] Another advantage lies in the fact that the geometric shape of the retaining means, in its longitudinal extension, increases the stability at the second end, i.e., the free end, of the retaining means. This is preferably achieved by having a certain radius at the transition to the second end of the retaining means, which allows for particularly satisfactory absorption of the forces exerted on the retaining means, especially pressure forces, and increases the shape stability of the second end of the retaining means. The second end, i.e., the free end, of the retaining means has a greater angle with respect to the horizontal of the retaining element than the first end, i.e., the fixed end, of the retaining means. The first end of the retaining means therefore has a smaller acute angle, so that The first end of the retaining device is oriented more horizontally relative to the second end. This greater angle at the second end, i.e., the free end, ensures that the retaining device's function is maintained even when excessive force is applied during disassembly or assembly, preventing deformation of the free end. When excessive force is applied, this force is preferentially transmitted to the first end, i.e., the fixed end, of the retaining device, thus preventing deformation of the second end, i.e., the free end.

[0021] According to an advantageous embodiment of the invention, the respective retaining element is held on the housing by complementarity of form and / or by complementarity of force.

[0022] In the preferred case, the respective retaining element is connected by complementary shape to a receiving element formed respectively on the outer face, on two opposite sides of the housing. Alternatively or further, the respective retaining element can be screwed by complementary force, via the front face of the housing, to a front panel disposed on the front face of the housing, and thus be retained.

[0023] One advantage lies in the fact that a retaining element connected to the housing can be easily replaced in the case of a connection based on complementary shapes or complementary forces, without damaging the housing. If the retaining means formed on the retaining element is nevertheless damaged during the installation or removal of the built-in appliance, the retaining element can be replaced quickly, without having to replace the entire housing with the retaining element.

[0024] Another advantage lies in the fact that, in the case of a connection by complementary force, the tensile or compressive forces exerted on the retaining element or the retaining means during assembly or disassembly are transmitted by the retaining means to the housing.

[0025] According to an advantageous embodiment of the invention, the respective retaining element is connected in one piece to the housing.

[0026] In the preferred case, the housing and the retaining element are manufactured in a single manufacturing process, for example an injection molding process, from a single material, for example a plastic, and are therefore produced as a single component. This has the advantage that a single-piece assembly of the housing and the retaining means is cost- and time-efficient.

[0027] Alternatively, for a one-piece assembly, a retaining element, for example made of metal, can be inserted into the injection mold for manufacturing the housing during a housing manufacturing process, for example during an injection molding process, and be cast with the housing and thus securely assembled. This has the advantage of eliminating further assembly steps and other mounting means for connecting the retaining element to the housing.

[0028] According to an advantageous embodiment of the invention, the respective retaining means has, in its longitudinal extension perpendicular to the direction of assembly and away from the housing, a snap-on lug.

[0029] One advantage is that the built-in appliance, in the mounted state, has a tight and secure fit and that the built-in appliance, in the mounted state, cannot be easily dislodged.

[0030] Another advantage lies in the fact that, thanks to the snap-in lug of the respective retaining means, the pressure force required to hold the recessed device in the vehicle's mounting space is increased. Indeed, the snap-in lug of the respective retaining means engages in a corresponding recess in the mounting means located in the mounting space. The snap-in lug exerts pressure in a direction opposite to the mounting direction against a surface of the recess in the mounting means, thus ensuring a tight fit of the recessed device in the vehicle's mounting space.

[0031] According to an advantageous embodiment of the invention, the retaining means has, in its longitudinal extension perpendicular to the direction of assembly and moving away from the housing, a first snap-in lug and a second snap-in lug, the first snap-in lug being formed parallel to the second snap-in lug on the retaining means.

[0032] One advantage lies in the fact that the pressure forces exerted on the installed device are distributed evenly across the first and second locking lugs of the retaining means, thus preventing deformation of the retaining means. Another advantage lies in the fact that the installed device, when installed, provides a tight fit within the vehicle's mounting space. The locking lugs of the respective retaining means, arranged parallel to each other, serve to guide the removal tool during the removal of the installed device. This has the advantage that the removal tool is guided between the two locking lugs of the respective retaining means and does not slip or cannot slip out of the retaining means.

[0033] According to an advantageous embodiment of the invention, the built-in device is characterized by the fact that, for each retaining means, at least one snap-in lug has at least one step.

[0034] One advantage lies in the fact that the flush-mount device, in its mounted state, can be snapped into place and held in various positions within the mounting means located in the mounting space. This increases the pressure force between the snap-in lug formed on the retaining means, or the step formed on the snap-in lug, and the mounting means. Furthermore, tolerances between the retaining means and the mounting means can be compensated, thus enabling the flush-mount device to be correctly installed and held within the vehicle's mounting space.

[0035] Another advantage lies in the fact that the formed step ensures that the snap-in lug of the retaining means remains engaged in the mounting means, even in the event of slight deformation of the retaining means, and that it firmly holds the built-in appliance in the mounted state.

[0036] According to an advantageous embodiment of the invention, the retaining means has, in its longitudinal extension, a tab deviated from the housing, perpendicular to the mounting direction.

[0037] One advantage lies in the fact that the tab formed on the retaining means allows a greater pressure force to be exerted on the retaining means, which makes it easy to release the retaining means, which is snapped with the mounting means, from each other and to extract the built-in device from the mounting space of the motor vehicle in a direction opposite to the direction of mounting.

[0038] Using the extraction tool, the retaining means is subjected to controlled pressure via the tab in the recess formed on the outer face of the housing. For this purpose, the second end, i.e., the free end, of the retaining means, in its longitudinal extension, perpendicular to the mounting direction, is preferably inserted into the recess in the housing. The forces exerted by the extraction tool on the tab and therefore on the retaining means are further transmitted to the housing via the first end, i.e., the fixed end, which is connected to the housing. This ensures that the retaining means does not deform uncontrollably and that the applied forces are concentrated on the fixed end of the retaining means.

[0039] According to an advantageous embodiment of the invention, the casing is made from a plastic material.

[0040] The preferred plastic material used for the housing is, for example, ABS (acrylonitrile-butadiene-styrene copolymer), polycarbonate, polyamide, polyester, or polyoxymethylene. These plastics exhibit good mechanical properties during processing.

[0041] One advantage lies in the fact that the plastic material is easy to process, which allows the casing to be manufactured in any shape. Furthermore, the manufacturing A plastic housing is economical. In the case of a plastic housing, it is particularly easy to create a recess with a bevel, for example using an injection molding process, in a single manufacturing step.

[0042] The above features and advantages may also be valid for the system described below.

[0043] According to a second aspect of the present invention, a system is provided comprising a built-in device as defined above and a mounting means, the mounting means being designed to hold the built-in device in a mounting space of a motor vehicle.

[0044] According to an advantageous embodiment of the invention and in particular of the system as defined above, the snap-in lug of the retaining means snaps into a corresponding recess of the mounting means.

[0045] One advantage lies in the fact that the built-in device and the mounting means are designed such that the system is retained within a mounting space in a motor vehicle and is protected against unauthorized dismantling or removal. In the snapped-in position, the snap-in lug of the retaining means exerts pressure against a surface of a recess in the mounting means and reliably holds the built-in device within the mounting space of the motor vehicle.

[0046] The flush-mounted device according to the invention finds its use, for example, in a motor vehicle, preferably for mounting at the tachograph unit in a heavy goods vehicle. Consequently, the system according to the invention is preferably used in a motor vehicle, in particular a heavy goods vehicle, in an installed state.

[0047] Advantageous developments of the invention also emerge from the features of the following description and figures.

[0048] For a better understanding of the principles of the present invention, embodiments of the invention will subsequently be explained in more detail with reference to the figures. The same reference numbers are used in the figures for identical elements or elements having the same effect and will not necessarily be described again for each figure. It will be understood that the invention is not limited to the embodiments shown and that the features described can also be combined or modified without departing from the scope of the invention.

[0057] [Fig.8] [Fig.8] represents a system comprising a built-in appliance and a mounting method.

[0058] Figure 1 shows a front-view perspective of a built-in appliance 100. The built-in appliance 100 is shown in Figure 1 after a front panel 110 has been mounted on a front face 215 of a housing 200 of the built-in appliance 100. The front panel 110 of the built-in appliance 100 closes the front face 215 of the housing 200 and is equipped with various functional elements that are not described in further detail here. When the front panel 110 is not mounted on the housing 200, the front face 215 of the housing 200 allows, for example, the insertion of electronic components such as printed circuit boards inside the housing 200.

[0059] The housing 200 of the built-in appliance 100 has an upper face 211, a lower face 212, a left side 213, a right side 214, and a rear face 216, which define a parallelepiped-shaped outer contour of the built-in appliance 100. On two opposite outer faces of the housing 200, namely on the left side 213 and on the right side 214, the housing 200 has two recesses 220 and 230, respectively, each having a bevel 221 and 231, the two respective recesses 220 and 230 being parallel to the mounting direction X of the built-in appliance 100. The respective bevel 221 and 231 formed on the housing 200 by the recess 220 and 230 extends perpendicularly Z to the side 214. respective of the housing 200 in a direction opposite to the mounting direction X of the built-in device 100.Furthermore, the housing 200 has, respectively on its outer face, on the two opposite sides, namely the left side 213 and the right side 214, a receiving element 280 for receiving and securing a retaining element 300 (not shown). The respective receiving element 280 is formed parallel to the mounting direction X on the outer face of the built-in appliance and extends parallel to the recesses 220, 230 formed on the housing.

[0060] Through recesses 111 to 114 are formed in the front panel 110 of the built-in appliance 100, which serve to dismantle the built-in appliance 100 of a motor vehicle mounting space. For this purpose, an extraction tool, not shown, for example in the form of a metal wire, is guided through the through recesses 111 to 114, and the recessed device 100 is released from the mounting means 500 inserted in the motor vehicle mounting space.

[0061] In another embodiment that is also conceivable in principle, but not shown here and not part of the invention, the housing 200 does not have recesses 220, 230 with bevels 221, 231 on two opposite outer faces, i.e., the left side 213 and the right side 214 of the housing 200. As shown in [Fig. 4], the retaining element 300 is inserted and fixed in a receiving element 280, in a direction opposite to the mounting direction X on the outer face of the housing 200. The respective retaining means 310, 320 of the retaining element 300 is guided directly on the outer face of the housing 200, in its longitudinal extension, at a second end 312, 322 disposed in a direction opposite to the mounting direction X, which is a free end, perpendicular to the mounting direction X.

[0062] Figure 2 provides further clarification and illustrates the built-in device described in Figure 1 in a rear perspective view. The housing 200 has, on its front face 215, two recesses 240, 250 respectively on the two opposite sides 213, 214. By means of the recesses 240, 250 arranged on each side, the retaining element 300, not shown in Figure 3, which is received and fixed in the mounted state in the receiving element 280, for example on the right outer side 214 of the housing, can further be connected to the front panel 110 mounted on the front face 215 of the housing 200. For this purpose, as shown in Figures 4 and 5, a commercially available mounting means 600 is used, for example a screw.

[0063] The housing 200 further has, on its front face 215, on the two opposite sides 213, 214, two respective tenons 242, 252. By means of the tenons 242, 252, the retaining element 300 located on each side 213, 214 is held and centered during assembly with the housing 200, so that the retaining element 300 is positioned parallel to the recess 220, 221 formed on the housing. The tenon can, for example, be formed as a single piece with the housing during an injection molding process. Corresponding to the through recesses 111 to 114 illustrated in [Fig. 1] and formed in the front panel 110 of the built-in appliance 100, the housing 200 has on its front face 215, on the two opposite sides 213, 214, two recesses 241, 251 respectively which serve to guide an extraction tool not shown. As illustrated in [Fig.[1] An extraction tool, not shown, is guided for this purpose through the through recesses 111, 112 in the front panel, and then through the recess 242, 252 on the front face 215 of the housing 200. The recesses 240, 241 and the tenons 242 formed on the left side 213 and the right side 214 of the housing 200 are arranged symmetrically here.

[0064] The housing 200 has on each side, namely the left side 213 and the right side 214, a retaining element 300 not shown.

[0065] Fig. 3 represents an example of the configuration of the retaining element 300 in the unmounted state with the housing 200, the retaining element 300 being designed in a mirror symmetrical manner (axis of symmetry 400) along a tab 330 in the mounting direction X. The retaining element 300 can be mounted and retained on the outer face of the housing 200, namely on the left side 213 and the right side 214.

[0066] As can be seen, the retaining element 300 comprises a first retaining means 310 and a second retaining means 320. The first retaining means 310 has, in its longitudinal extension in the mounting direction X, a first end 311 which is solidly connected to the retaining element 300 and a second end 312 which is free and movable. In this embodiment, the second end 312, i.e. the free end, of the retaining means 310, has a larger angle with respect to the horizontal of the retaining element than the first end 311, i.e. the fixed end, of the retaining means 310. The first end 311 of the retaining means 310 thus has a lower acute angle of 13°, such that the first end 311 of the retaining means 310 is oriented more flatter with respect to the second end 312 of the retaining means 310. The second end 312 of the retaining means has an angle of 35°.

[0067] The first retaining means 310 further has, in its longitudinal extension, between the first end 311 and the second end 312, on its outer contour, a first snap-in lug 313 and a second snap-in lug 315, the first snap-in lug 313 being arranged parallel to the second snap-in lug 315 on the retaining means 310. The two snap-in lugs 313, 315 are here respectively placed at 90° in the longitudinal extension of the retaining means 310.

[0068] Each of the two snap-in lugs 313, 315 respectively has a step 314, 316. In one embodiment, each of the two steps 314, 316 respectively has two steps. The steps 314, 316 of the respective snap-in lugs 313, 315 are designed so that, as shown in [Fig.7], the retaining element 300 snaps respectively with the respective snap-in lugs 313, 315, 323, 325 formed on the first retaining means 310 and the second retaining means 320, with the respective steps 314, 316, 324, 326 formed on the snap-in lugs, with a corresponding respective recess 510, 511 in the mounting means 500.

[0069] In its longitudinal extension, the retaining means 310 is bent between the first end 311 and the second end 312. Since the retaining means 310 has a free end 312, the retaining means 310 is designed elastically in its longitudinal extension, which allows the retaining means 310 to be disengaged from the mounting means 500. For this purpose, the first retaining means 310 has, for example, in its longitudinal extension, between the first locking lug 313 and the second locking lug 315, a tab 317 deflected perpendicularly to the mounting direction X, by means of which the retaining means 310 is disengaged from the mounting means 500 during disassembly. For this purpose, an extraction tool exerts pressure on the tab 317, and the first retaining means 310, with the two locking lugs 313 and 315, is disengaged from the recess 510 of the mounting means 500 (not shown here).

[0070] The second restraint means 320, which is arranged parallel to the first restraint means 310, has the same structure and the same function as the first restraint means 310.

[0071] Fig. 3 further shows, in a direction opposite to the mounting direction X, an example of the configuration of a first flange 340 and a second flange 350 on the retaining element 300. The flanges 340, 350 are arranged in such a way that they serve, when mounting the retaining element 300, as illustrated in Figures 4 and 5, on the outer face of a housing 200 of a built-in device 100 and for the connection to a front panel 500 mounted on the front face of the housing 215.

[0072] The first flange 340 has a recess 341, which allows the retaining means 311 of the retaining element 300 to be connected to the housing 200 and to the front panel 110 mounted on the front face of the housing 215. A mounting means 600, not shown, for example a screw, is used for this purpose. The flange 340 also has a recess 342 which serves to guide the extraction tool, not shown here. As shown in Figures 4 and 5, the extraction tool can be guided through the through recess 111 formed in the front panel, and then through the corresponding recess 241 in the front of the housing. Next, the extraction tool continues to be guided along the outer face of the housing until it reaches the retaining means 311 of the retaining element 300. The extraction tool is guided between the two snap-in lugs 313, 315 formed on the retaining means 311 and exerts pressure on the tab 317, thus releasing the retaining means 311 from the mounting means 500.

[0073] The second flange 350 has a structure and function equivalent to those of the first flange 340. Each of the flanges 340, 350 has another recess 343, 353 which serves to center the retaining element 300 with the tenon 242, 252 respectively formed on the housing, as illustrated in [Fig.2].

[0074] Furthermore, [Fig. 3] shows, in its longitudinal extension between the first retaining means 310 and the second retaining means 320, a tab 330 with a lug. The tab 330 extends parallel to the first retaining means 310 and the second retaining means 320. The retaining element 300 can be inserted and thus fixed in a receiving element 280 by means of the tab 330, as illustrated in [Fig.4], in a direction opposite to the mounting direction X on the outer face of the housing 200.

[0075] The retaining element 300 has an axis of symmetry 400, such that the first retaining means 310 formed on the retaining element 300 and the second retaining means 320 are symmetrically arranged with respect to each other on the retaining element 300. The two retaining means 310 and 320 have an identical structure and mode of operation. The same applies to the first flange 340 and the second flange 350 formed on the retaining element 300.

[0076] Figure 4 shows the retaining element 300 described in Figure 3 mounted on the right side 214 of the housing 200 of the built-in appliance 100. In one embodiment, the tab 330 of the retaining element 300 is inserted and held in the receiving element 280 formed on the right outer side 214 of the housing 200, in a direction opposite to the mounting direction X. The retaining element is further connected by a mounting means 600, for example a screw, in a direction opposite to the mounting direction X, on the front side 215, to the housing 200 and to the front panel 110 of the built-in appliance 100 mounted on the front side 215 of the housing 200. The retaining element 300 is thus protected against being withdrawn, in the mounting direction X, from the element of retention 280 from case 200.

[0077] Furthermore, [Fig.4] represents the first retaining means 310 and the second retaining means 320 formed on the retaining element 300 as well as the recesses 220, 230 corresponding to the two retaining means 310, 320 on the housing 200, having respectively a bevel 221, 231, the respective recess 220, 230 being formed parallel to the mounting direction X and to the respective retaining means 310, 320.

[0078] Fig. 5 represents a perspective view showing a recess 214 and a bevel 231 formed on the inset device 100 to receive and guide the second retaining means 320 of the retaining element 300 shown in Fig. 3. The bevel 231 illustrated in [Fig. 5] is formed perpendicularly Z to the right-hand outer side 214 of the housing 200, in a direction opposite to the mounting direction X, and has an angle α of 135° with respect to the corresponding recess 230 presenting the bevel 231. The second retaining means 320 shown can be pushed in and received in the recess 214 provided for this purpose when the built-in appliance 100 is removed. In particular, the second free end 322 of the retaining means 320 is here pushed in the recess 230 and guided onto the bevel 231 on the outer face of the housing 200.

[0079] Figure 6 represents a mounting means 500 as provided according to DIN ISO 7736

[0080] for installation in a mounting space of a motor vehicle. The mounting means 500 here has, respectively on at least two opposite sides, for example the left and right sides of the mounting means, two retaining elements 520, 521 with which the mounting means 500 is held after being inserted into the mounting space of the motor vehicle. After insertion of the mounting means 500, the retaining elements 520, 521 are folded outwards, which holds the mounting means 500 in the mounting space and prevents it from being removed in a direction opposite to the mounting direction X. In an embodiment, the mounting means 600 can also be held in the mounting space by means of screws.

[0081] Furthermore, [Fig. 6] shows two recesses 510, 511 on two opposite sides, namely the left and right sides, of the mounting means. Once the flush-mounted device has been inserted into the mounting means, as illustrated in [Fig. 7], the retaining means 310, 320 located on the housing 200 of the flush-mounted device 100 snap respectively into the corresponding recesses 510, 511 of the mounting means 500. The flush-mounted device 100 is thus locked and held in the mounting space of the motor vehicle by the mounting means 500, which prevents it from being removed.

[0082] Fig. 7 illustrates by way of example how the built-in device 100, after being inserted in the mounting direction X into the mounting means 500, in the mounting space of the motor vehicle, is held by the retaining element 300 mounted on the right side 214 of the housing 200. The second retaining means 320 formed on the retaining element 300 is shown here with the two snap-in lugs 323, 325 formed therein.

[0083] Once the built-in appliance 100 is inserted into the mounting means 500, the first snap-in lug 323 and the second snap-in lug 325 of the second retaining means 320 snap into place, in the final mounting position, in the corresponding recess 511 formed in the mounting means 500. The step 324 formed on the first snap-in lug 323 and the step 326 formed on the second snap-in lug 325 rest respectively on an edge of the recess 511 of the mounting means 500 and prevent the built-in appliance from being dislodged and removed in a direction opposite to the mounting direction.

[0084] The same principle applies to the first retaining means 310 of the retaining element 300 as well as to the second retaining element 300 mounted on the left side 213 of the housing 200.

[0085] Figure 8 shows the system 10 comprising a built-in device 100 and a mounting means 500 in the unmounted state. The mounting means 500 allows the device to be fixed and held in the mounting space of a motor vehicle. built-in 100 and retaining elements 300 mounted on the housing 200, on the left side 213 and on the right side 214, of the built-in appliance.

[0086] Overall, the example illustrates how the invention makes it possible to easily construct a housing and the retaining elements mounted thereon for a built-in appliance, so that the retaining elements are not deformed or damaged during the removal of the built-in appliance. The examples further illustrate a system comprising this built-in appliance and a mounting means intended for installation in a mounting space of a motor vehicle.
