Description

The present invention relates to a holding element for an installation device for installation in a motor vehicle. The invention furthermore relates to a system having a holding element of this type mounted on an outer side of the installation device for installation in an installation space, in particular an installation space of an installation device provided for front installation, of a motor vehicle.Retaining elements of this type are used today in almost any motor vehicle for installing an installation device, for example a chronograph unit, also referred to as a trip recorder.A holding element of the type mentioned at the beginning has a base plate and a holding means, wherein the base plate is formed integrally with the holding means. The holding means has a plurality of sections, wherein a first section of the holding means adjoins the base plate forming a first angle directed away from the base plane at a first angle between a base plane defined by the base plate and the first section counter to the installation direction in which the installation device is installed in the motor vehicle. The holding element is designed in such a way that the built-in device can be held firmly in the motor vehicle in the installed state by means of the holding means.The possibilities for fastening the built-in device in the installation space of the motor vehicle by means of a retaining element are usually oriented here to DIN ISO 7736:1985-04. In this case, a lateral fastening of the built-in device in the installation space of the motor vehicle is preferably proposed, in which the built-in device has a holding element. The holding element, which is mounted on the outer side of a housing of the built-in device, latches into a corresponding recess of a mounting means in the installation space of the motor vehicle, which recess serves for the installation of the built-in device into the installation space of the motor vehicle. The built-in device is thus secured and held by the holding element in the installation space of the motor vehicle against removal.A disadvantage of this is that with such retaining elements of the prior art, when the built-in device is removed from the installation space of the motor vehicle, the retaining element mounted on the built-in device is damaged or deformed. In this case, a removal tool abuts against the holding means formed on the holding element or pushes under the holding means, between the housing of the built-in device and the holding means, and deforms it in an uncontrolled manner at any point, as a result of which removal of the built-in device from the installation space of the motor vehicle is made more difficult or even impossible. Furthermore, problems arise when the built-in device is mounted again. The dimensions and tolerances to be observed of the built-in device with the holding element mounted thereon are no longer observed due to uncontrolled deformation of the holding means formed on the holding element. The built-in device can only be inserted and locked into the installation space of the motor vehicle with difficulty.DE 103 57 799 A1 discloses an adapter system for installing an installation device into an installation space of an installation device provided for front installation in a motor vehicle. The adapter system comprises at least two separate sub-elements which are arranged on two opposite sides of the built-in device. Each partial element comprises the built-in device in a U-shaped manner.Furthermore, EP 1 225 095 A1 discloses an installation device to be mounted in an installation opening. The built-in device is fixedly connected on two opposite sides in each case to a retaining spring which in each case has at least one spring arm which has a latching nose which latches into a stationary contact edge. In addition to the latching lug, at least one resilient catch lug is provided, which, when the mounting device is moved out of the mounting opening, after the latching lug has been released, can engage with a steep catch surface in a form-fitting manner against a retaining surface.The object of the present invention is to propose a holding element and a system with such a holding element, in which a secure and reliable mounting or dismantling of the installation device, on which the holding element is mounted, is made possible without the holding means formed on the holding element being damaged by the removal tool or being deformed in an uncontrolled manner at any point on the holding means.The object is achieved according to the invention by the features of the independent claims. Advantageous embodiments can be gathered from the dependent claims.According to a first aspect of the present invention, the holding means has, in its elongate extent counter to the installation direction between the base plate of the holding element and a third section of the holding means, a second angle pointing towards the base plane between the first section and an adjoining second section of the holding means and a third angle pointing towards the base plane between the second section and the adjoining third section of the holding means.In the holding element according to the invention, the configuration and shape of the holding means formed thereon, which has a first, a second and a third angle, is particularly advantageous. As a result, forces acting particularly well on the holding means, in particular compressive forces acting during disassembly and assembly, can be absorbed by the second section of the holding means, as a result of which the holding means permits deformation in the non-critical region and the holding means is dimensionally stable with respect to forces acting thereon.By the configuration and shaping of the holding means, forces acting on the first section or the first bend of the holding means, which is firmly connected at an angle to the base plate of the holding element, can also be further conducted. It is thus ensured that the retaining means deforms in its elongate extent only at the first section or the first bend and the second and third sections of the retaining means adjoining it retain its shape and securely retain the built-in device in the installation space.According to an advantageous embodiment of the invention, the first angle has an angle range between 10° and 16°, preferably an angle of 13°.In the preferred case, the first angle formed between the base plate of the holding element and the first section of the holding means forms an acute angle. Experiments have shown that acute angles in a range between 10° and 16°, preferably 13°, are particularly well suited. Furthermore, the first bend is formed as a sharp bending edge.During a production process, a punch presses the workpiece to be deformed, here the holding means of the holding element, into a die of a die, whereby the holding means is specifically brought into its desired shape and thus the sharp bending edge is formed between the base plate and the first section of the holding means.Experiments have shown that the first angling with an acute angle is particularly advantageous. In particular, if the first bend has a sharp bending edge. As a result, it is possible to absorb particularly well acting forces which act in this region of the holding means.An advantage is also that forces acting on the holding means, in particular compressive forces, can be directed in a targeted manner onto the first bend by the removal tool during disassembly or assembly and a plastic deformation takes place at the first bend between the base plate and the first section. This prevents the second section and third section of the holding means adjoining the first section from being deformed. It is ensured that the holding means still retains its function for securely holding the built-in device in the installation space.According to an advantageous embodiment of the invention, the second angle between an extension of the first section and the second section has an angle range between 11° and 17°, preferably an angle of 14°.In the preferred case, the holding means is designed such that the second bend formed between the first section of the holding means and the adjoining second section of the holding means likewise forms an acute angle, wherein the second bend has a sharp bending edge.One advantage is that, as already described above, forces which act on the holding means, in particular on the second section of the holding means, during disassembly or assembly are directed in a targeted manner into the first section of the holding means. This is intended to specifically produce a plastic deformation in the first section of the holding means. The second and third portions of the holding means are prevented from being deformed. The holding means, in its second and third sections, continues to maintain its function for holding the installation device in the installation space.If the holding means is nevertheless deformed during disassembly or assembly, a deformation first takes place at the sharp bending edge, as a result of which the remaining part of the holding means retains its shape.According to an advantageous embodiment of the invention, the third angle between an extension of the second section and the third section has an angle range between 32° and 37°, preferably an angle of 34°.Experiments have shown that angles in this angle range are particularly advantageous so that the third angle and the third section are dimensionally stable with respect to forces acting thereon, in particular compressive forces.One advantage is that the forces acting on the holding means do not lead to any deformation at the third bend or the third section of the holding means. Because the third bend has a larger angle with respect to the first and second bends, the third bend and the third section of the holding means are dimensionally stable with respect to forces acting thereon. The third angle as well as the third portion are not deformed.According to an advantageous embodiment of the invention, the second section has, in its elongate extent in the direction of the base plane and counter to the installation direction, a gradient of between 0.5° and 2°, preferably a gradient of 1°.An advantage is that the removal tool can be guided well due to the gradient of the second section. As a result, the holding means can be pressed particularly well by means of a removal tool and can be released from the installation space. The forces acting on the holding means are directed in a targeted manner into the first section of the holding means on account of the gradient. This has the advantage that the second section of the holding means is not deformed and retains its shape for holding in the installation space of the motor vehicle.According to an advantageous embodiment of the invention, a radius between 3 mm and 5.5 mm, preferably a radius of 5 mm, is present between the second section and the adjoining third section, at the third angle.One advantage is that the holding means is more dimensionally stable with respect to acting forces at this point because of the radius formed and can absorb these forces particularly well without the holding means being deformed at this point. In addition, the transition between the second and third sections of the holding means is, due to the formed radius, resilient with respect to a sharp bending edge.According to an advantageous embodiment of the invention, the holding means has a rounded portion in its elongate extent in the direction of the base plane and in the installation direction on the third section of the holding means, wherein the rounded portion has a radius of between 0.3 mm and at most half the material thickness of the third section of the holding means, preferably a rounded portion having a radius of 0.3 mm.An advantage is that, due to the rounding at the third section of the holding means, wherein the third section is a free loose end, it can be guided particularly well on the outer side of the housing in the event of a force acting on the holding means, without the free end of the third section tearing into the material of the housing and the third section of the holding means thereby being damaged or deformed. The rounding at the third section achieves particularly good sliding friction.According to an advantageous embodiment of the invention, the holding means has, in its elongate extent directed counter to the base plane, at least one first latching nose on a longitudinal side of the second section of the holding means.One advantage is that, by means of the latching lug formed on the holding means, the built-in device in the installed state has a firm and secure seat in the installation space of the motor vehicle and the built-in device in the installed state cannot be easily detached from the installation space.A further advantage is that the contact pressure force for holding the built-in device in the installation space of the motor vehicle is increased by means of the latching lug of the holding means. In this case, the latching lug of the holding means can latch into a respectively corresponding recess, for example in an assembly means additionally arranged in the installation space of the motor vehicle. The latching lug presses against a surface of a recess of the mounting means counter to the installation direction and thus ensures a firm and secure seat of the installation device in the installation space of the motor vehicle.According to an advantageous embodiment of the invention, the holding means has a second latching nose on a longitudinal side of the second section of the holding means, wherein the first latching nose is formed parallel to the second latching nose.One advantage is that the forces acting on the holding element in the installed state, in particular compressive forces, are distributed uniformly over the first latching nose and the second latching nose of the holding means, whereby deformation, in particular in the second section of the holding means, is avoided.A further advantage is that the built-in device, in the installed state, has a fixed seat in the installation space of the motor vehicle. In this case, at least one of the two latching noses formed on the holding means latches into a respectively corresponding recess, for example of the mounting means arranged in the installation space of the motor vehicle. The latching lugs press against a surface of the recesses of the mounting means counter to the installation direction and thus ensure a firm seat of the installation device in the installation space of the motor vehicle. In addition, the parallel locking noses of the holding means serve to guide the removal tool during the disassembly or assembly of the built-in device into the installation space of the motor vehicle. This has the advantage that the dismantling tool is guided between the two latching noses of the holding means and does not slide laterally, as a result of which the holding means can be deformed.According to an advantageous embodiment of the invention, at least one latching nose of the holding means has at least one step.One advantage is that, by means of the step formed on the latching lug of the holding means, the built-in device can latch and be held in different positions in the installation space of the motor vehicle, for example in an installation means additionally arranged in the installation space, in the installed state. As a result, the pressing force between the latching lug formed on the holding means or the step formed on the latching lug and, for example, the mounting means inserted in the installation space of the motor vehicle can be increased. In addition, tolerances between the holding means and the mounting means can be compensated, as a result of which the built-in device can be properly mounted and held in the installation space of the motor vehicle and has a fixed seat.A further advantage is that the step formed on the latching lug ensures that the latching lug of the holding means continues to latch in the installation space in the installation space even in the event of a slight deformation of the holding means and securely holds the installation device in the installed state.According to an advantageous embodiment of the invention, the holding means has a tab on the second section of the holding means in its elongate extent in the installation direction and directed counter to the base plane.An advantage is that, due to the tab formed on the second section of the holding means with the removal tool, during the dismantling or mounting of the built-in device from the installation space of the motor vehicle, a greater compressive force can be exerted on the holding means without the holding means being deformed. The holding means, which in the assembled state is locked in the installation space of the motor vehicle, is released and the built-in device can easily be pulled out of the installation space of the motor vehicle counter to the installation direction.A further advantage is that the holding means is pressed via the tab in a controlled manner in the direction of the base plane, to the outer side of the housing of the built-in device by means of the removal tool. In this case, the third section, the free end, of the holding means is preferably pressed against the housing in its elongate extent to the installation direction in the direction of the base plane, as a result of which deformation of the holding means is avoided. The force acting on the tab and thus on the holding means by the removal tool is also transmitted to the housing via the second portion of the holding means, which is firmly connected to the base plane of the holding means and to the housing of the built-in device. This ensures that the holding means does not deform in an uncontrolled manner at an indeterminate location of the second and third sections of the holding means, and the forces introduced into the holding means concentrate in a targeted manner on the first section of the holding means.According to an advantageous embodiment of the invention, the holding element additionally has a second holding means, wherein the first holding means and the second holding means are of the same structure and are arranged symmetrically with respect to one another.One advantage is that the built-in device has a firm and secure seat in the installation space of the motor vehicle. As a result, the built-in device is secured in the installation space against uncontrolled slipping out, for example in the event of an accident. In addition, tilting of the built-in device in the installation space after assembly is prevented if the holding element or the first holding means and the second holding means latches, for example, with the mounting means arranged in the installation space of the motor vehicle.Furthermore, there is an advantage in that the force acting during disassembly or assembly on the first holding means arranged symmetrically to one another and the second holding means is uniformly conducted further via the two holding means on the base plate of the holding element and then on the housing of the built-in device and distributed, so that the first and second holding means are not deformed. However, if the first or second retaining means is deformed, it is carried out in a targeted manner in the respective first section of the retaining element or the respective first angle between the base plate of the retaining element and the adjoining first section of the respective retaining means.The same applies to the pressing forces acting on the respective holding means in the assembled state. One advantage is that after the installation device has been mounted in the installation space of the motor vehicle, the pressing forces acting on the first holding means and the second holding means are distributed uniformly on the housing of the installation device, so that a secure seat and hold of the installation device is ensured.According to an advantageous embodiment of the invention, the holding element has a tongue adjoining the base plate parallel to the at least one holding means counter to the installation direction.One advantage is that the retaining element can be mounted in a receiving element simply and quickly by insertion and latching on the outer side of the housing of the built-in device by means of the tongue formed on the base plate and can be disassembled again when a defective retaining element is replaced. In addition, the tongue ensures that the retaining element in the assembled state rests flat on the outer side of the housing.A further advantage is that forces acting on the holding element, for example compressive forces acting during disassembly by the removal tool, are transmitted to the housing of the built-in device via the tongue formed on the holding element. In addition, the tongue formed on the holding element offers a stable seat of the holding element on the outer side of the housing of the built-in device against tilting and slipping. Because the holding means rests flat on the outer side of the housing and is connected to the housing wall, the holding means is not displaced in an uncontrolled manner or is even bent during the dismantling of the built-in device from the installation space. This has the advantage that the built-in device does not become caught and tilted when it is removed from the installation space or the mounting means arranged in the installation space.According to an advantageous embodiment of the invention, the holding element has, parallel to the at least one holding means, counter to the installation direction, at least one web adjoining the base plate and having a connecting flange.One advantage is that the web of the retaining element has a larger bearing surface on the housing of the built-in device, and forces acting on the retaining element are absorbed particularly well and are distributed to the housing of the built-in device. In addition, the holding element thereby has a secure seat on the housing wall.A further advantage is that the holding element can be connected to a front side of the built-in device by means of the connecting flange adjoining the web, so that the holding element, when the built-in device is pulled out of the installation space of the motor vehicle counter to the installation direction, has a firm and secure seat and is not pulled out of the receiving element.According to an advantageous embodiment of the invention, the holding element is made of a metal.One advantage is that a holding element made of metal is robust with respect to forces acting thereon and can be easily shaped and bent. This is advantageous in particular when, for example, compressive forces act on the holding element during assembly or disassembly by means of the removal tool. In addition, metal has high strength of the material. Compared to a holding element made of plastic, for example, the material has a slower fatigue and aging in the case of a holding element made of metal. A further advantage is that a holding element made of metal can be brought into any desired shape quickly and cost-effectively. In addition, in the case of a holding element made of metal, sharp bending edges can be formed, which are particularly well suited for a targeted force absorption and deformation at a desired location of the holding means.According to an advantageous embodiment of the invention, the holding element is manufactured as a stamped and bent part.One advantage is that the holding element can be manufactured individually as a stamped and bent element according to the specifications and requirements of the respective technical requirements. A further advantage is that stamped and bent parts are quick, precise, cost-effective and energy-saving in production. Stamped and bent parts also offer high flexibility in the shape and configuration of the component to be produced and can be produced quickly in a large number of pieces. Furthermore, the holding means formed on the holding element can be produced in virtually any desired configurations, in particular with regard to the angular ranges and radii formed on the holding means. In the case of a stamped bent part, the sharp bent edges can be produced particularly well.According to an advantageous embodiment of the invention, the holding means of the holding element is designed to be elastically resilient in its elongate extent perpendicular to the base plane.One advantage is that the holding means can be elastically deformed to a small extent under forces acting thereon, for example under pressure forces acting thereon by the removal tool. No direct plastic deformation and deformation of the holding means occur when forces are exerted on the holding means by the removal tool.In the case of elastic deformation, the holding means returns to its initial shape after the force acting on the holding means is removed. Thus, there is an advantage in that the holding means does not immediately lose its shape under forces acting thereon, for example pressure forces, and thus retains its original initial shape. This ensures that the holding means performs its function as a holding element and the built-in device securely locks in the installation space of the motor vehicle in the installed state.A further advantage is that if in the preferred case the holding means is deformed in the first section, preferably the first bend between the base plate and the first section, the third section of the holding means, the free loose end, returns to its initial shape, thereby ensuring that the built-in device securely locks in the installation space.The aforementioned features and advantages may also apply to the system described below.According to a second aspect of the present invention, a system is provided, comprising a first holding element and an installation device, wherein the installation device has a cuboidal housing and the housing has the first holding element on an outer side, on two opposite sides of the housing, and a second holding element corresponding to the first holding element, wherein the two holding elements are designed to hold the installation device in an installation space of a motor vehicle.One advantage is that the built-in device is securely held in the installation space of the motor vehicle by means of the first holding element and the opposite second holding element and is secured against unauthorized disassembly. The latching nose of the first holding means and of the second holding means presses in the latched state against the surface of the recess of the mounting means mounted in the installation space of the motor vehicle and thus holds the built-in device securely in the installation space of the motor vehicle.According to an advantageous embodiment of the invention, the respective holding element is held on the housing of the built-in device in a form-fitting and / or force-fitting manner.In the preferred case, the respective holding element is connected in a form-fitting manner to a receiving element which is formed in each case on the outer side on two opposite sides of the housing. Alternatively or additionally, the respective holding element can be screwed in a force-fitting manner via the front side of the housing to a front panel arranged on the front side of the housing and thus held.One advantage is that a holding element connected to the housing can be easily replaced in the case of a positive or force-fit connection without the housing being damaged. If the holding means is nevertheless damaged during the assembly or disassembly of the built-in device, the holding means can be replaced quickly without the entire housing having to be replaced with the holding means.A further advantage is that in the case of a force-fit connection, the tensile forces or compressive forces acting during assembly or disassembly on the holding element or the holding means formed thereon are transmitted to the housing. In addition, the holding element thereby always has a fixed seat on the housing of the built-in device.The holding element according to the invention is used, for example, in a motor vehicle, preferably for mounting a chronograph unit in a lorry. Accordingly, the system according to the invention is preferably used in an installed state in a motor vehicle, in particular a lorry.Advantageous refinements of the invention also result from the features of the following description and of the figures.To better understand the principles of the present invention, embodiments of the invention are explained in more detail below with reference to the figures. Identical reference numerals are used in the figures for identical or identically acting elements and are not necessarily described again for each figure. It is to be understood that the invention is not limited to the illustrated embodiments and that the described features may be combined or modified without departing from the scope of the invention as defined in the appended claims.They are shown in schematic, schematic diagram: FIG. 1 shows a perspective view of a holding element for an installation device, FIG. 2 shows a right-hand view of a holding means of the holding element shown in FIG. 1, FIG. 3 shows a right-hand view of an installation device with a retaining element mounted on the housing of an installation device, FIG. 4 shows a perspective view of an installation device with the retaining element mounted on the housing of an installation device, FIG. 5 shows a system with an installation device and a holding element to be mounted thereon.FIG. 1 shows a perspective view of an exemplary configuration of the holding element 100 in the non-assembled state with the housing 300, wherein the holding element 100 is constructed along a tongue 130 in mirror symmetry in the assembly direction X (axis of symmetry 400). The holding element 100 has a base plate 103 with an upper side 101 and a lower side 102 arranged parallel thereto, wherein the lower side 102 of the holding element 100 in the mounted state rests flat on an outer side of the housing of the paving apparatus, as can be seen in FIG. 3, and is firmly connected to the housing 300 of the paving apparatus 200. The underside 102 of the base plate 103 defines the base plane of the holding element and extends in the X-Z plane.A first holding means 110 and a second holding means 140 are connected to the base plate 103, counter to the installation direction X in which the installation device 200 is installed in the motor vehicle, wherein the base plate 103 is formed integrally with the first holding means 110 and the second holding means 140. The first holding means 110 and the second holding means 140 each have a plurality of sections. In the preferred case, the first section 111, 141 of the holding means 110, 140, which adjoins the base plate 103 counter to the installation direction X of the installation device 200 into the installation space of the motor vehicle, is a fixed section and is fixedly connected to the base plate, wherein the third section 113, 143, which is a free end, is movable and guidable on the housing 300 of the installation device 200.The first holding means 110 adjoining the base plate 103 and the second holding means 140 extend here in each case counter to the installation direction X of the installation device 200 into the installation space of the motor vehicle and protrudes in its elongate extent counter to the installation direction X pointing away from the base plane of the holding element 100 in the direction of the upper side 101 of the holding element 100.In an exemplary embodiment, the first holding means 110 has a second portion 112 in its elongate extent, between the first portion 111 and the third portion 113, wherein the second portion 112 has a first latching nose 119 and a second latching nose 121 on the outer contour and the first latching nose 119 is arranged on the holding means 110 parallel to the second latching nose 121. The two latching noses 119, 121 are each set up 90° in the elongate extension of the holding means 110 opposite to the base plane. Each of the two latching noses 119, 121 has a step 120, 122, respectively, wherein each of the two steps has two individual steps, respectively. The steps 120, 122 are designed in such a way that the holding element 100 with the latching noses 119, 121 formed on the first holding means 110 or the steps 120, 122 respectively formed on the latching noses can latch with a recess corresponding in the mounting means, not shown here.The second holding means 140 has the same structure and the same function as the previously described first holding means 110 and the latching noses formed on the holding means.In its longitudinal extension, the holding means 110 is bent between the base plate 103 and the third section 113 of the holding means 110. Due to the fact that the holding means 110 has a free loose end on the third section 113, the holding means 110 is designed to be elastically resilient in its elongate extent. As a result, the holding means 110 can be released again in the locked state, from the mounting means, not shown, in the installation space of the motor vehicle. The first holding means 110 also has, in its elongate extent in the installation direction X and directed counter to the base plane, on the second section 112 of the holding means 110, a deflected tab 123 between the two latching noses 119, 121, by means of which the holding means 110 is released from the mounting means during disassembly. In this case, a removal tool presses on the tab 123 and the first holding means 110 with the two latching noses 119, 121 is released from the corresponding recess, not shown, of the mounting means.Furthermore, FIG. 1 shows an exemplary configuration for a first web 174 adjoining the base plate 103 counter to the installation direction X and a second web 184 with a first connecting flange 170 and second connecting flange 180 each adjoining the respective web. The first web 174 with the first connecting flange 170 and the second web 184 with the second connecting flange 180 are of the same construction and are arranged symmetrically to one another on the base plate 305. The first web 174 with the adjoining first connecting flange 170 is arranged centrally and parallel between the tongue 130 and the first holding means 110. The second web 184 with the second connecting flange 180 is arranged centrally and parallel between the tongue 130 and the second retaining means 140.The two connecting flanges 170, 180 are arranged so as to serve for mounting the holding element 100, as shown in FIGS. 3 and 4, on the outer side of a housing 300 of an installation device 200 and for connecting to a front panel 210 mounted on the front side of the housing 305.In an exemplary embodiment, the first connecting flange 170 has a recess 171, whereby the holding element 100, as can be seen in FIG. 4, is connected to the housing 300 and the front panel 210 mounted on the front side of the housing 305. For this purpose, a mounting means 500, not shown, for example a screw, is used. Furthermore, the flange 170 has a second recess 172, which serves for guiding the removal tool, not shown here. As shown in FIGS. 3 and 4, the removal tool can be guided through the through-recess 211 formed in the front panel further through the recess 311 corresponding to the front side of the housing. Subsequently, the removal tool is guided further on the outer side of the housing up to the holding means 110 of the holding element 100. The removal tool is guided between the two latching noses 119, 121 formed on the second section 112 of the holding means 110 and presses on the tab 123, whereby the holding means 110 is released from the mounting means, not shown. Furthermore, the connecting flange 170 has a third recess 173, which serves for centering the holding element 100 with a pin 310 formed on the housing 300, as can be seen in FIG. 3.The second flange 180 has a structure and function corresponding to the first flange 170.Furthermore, FIG. 1 shows a tongue 130 with a tab 131 formed in the direction of the base plane, wherein the tongue 130 adjoins the base plate 103 counter to the installation direction X and the tongue 130 is formed parallel between the first holding means 110 and the second holding means 140. The holding element 100 can be inserted into a receiving element 320 and thus fixed by means of the tongue 300, as can be seen in FIGS. 3 and 4, counter to the mounting direction X on the outer side of the housing 300. In this case, the tab 131 formed on the tongue 130 latches with the housing 300 of the built-in device 200.The holding element 100 has an axis of symmetry 400, as a result of which the first holding means 110 formed on the holding element 100 and the second holding means 140 and the first web 174 and the second web 184 with the respectively adjoining first flange 170 and second flange 180 are formed on the holding element 300 symmetrically with respect to one another.FIG. 2 shows, by way of example, a view of the second holding means 140 of the holding element 100 illustrated in FIG. 1 from the right. As can be seen in the view, the holding element 100 has a base plate 103 with an upper side 101 and a lower side 102 running parallel thereto. The base plate 103 is adjoined counter to the installation direction X, in which the installation device 200 is installed in the motor vehicle, by the first section 141 of the second holding means 140. The first section 141 of the second holding means 140 adjoins the base plate 103 at a first angle α between the base plane defined by the base plate 103 and the first section 141, wherein a first bend 144 directed away from the base plane in the direction of the upper side 101 is formed. Furthermore, the holding means 140 has, in its elongate extent counter to the installation direction X between the base plate 103 of the holding element 100 and a third section 143 of the holding means 140, a second bend 145 directed towards the base plane, between the first section 141 and an adjoining second section 142 of the holding means 140, and a third bend 146 directed towards the base plane, between the second section 142 and the adjoining third section 143 of the holding means 140.In this exemplary embodiment of FIG. 2, the first bend 144 has an acute angle α of 13°, wherein the first bend 144 is formed as a sharp bending edge. The second bend 145, between an extension of the first section 141 and the second section 142 of the holding means 110, likewise has an acute angle α2of 14° and is also designed as a sharp bending edge. The third bend 146, between an extension of the second section 142 and the third section 143, has an angle α3of 34° with a radius r3of 5 mm. The first section 141 of the holding means 140 thus has a smaller angle α with respect to the third section 143, so that the first section 141 is oriented flatter with respect to the third section 143. As a result of the radius r 3 formed between the third section 143 and the second section 142 adjoining it, the third section 143 is resilient with respect to forces acting thereon. The second section 142 arranged between the first section 141 and the third section 143 has a gradient of 1° in its elongate extent in the direction of the base plane and counter to the installation direction X. As can be seen in FIG. 1, the second section 142 also has, on its longitudinal side, a latching nose 151 with a step 152 formed on the latching nose in its elongate extent directed counter to the base plane.As shown in FIG. 2, the holding means 140 is fixedly connected at its first section 141 to the base plate 103 in its elongate extent in the mounting direction X and is configured to be freely movable at the third section 143.The third section 143 of the holding means 140 has a rounded portion r 4 with a radius of 0.3 mm in the direction of the base plane and in the installation direction X, whereby the free loose end of the third section 143 in the mounted state on the housing 300 of the installation device can be guided during the dismantling or installation without the holding means 140 being deformed on the third section 143. The rounded portion r4 with the radius formed at the free end of the third section 143 ensures a sliding movement on the housing without the free end tearing into the material of the housing. If the second holding means 140 is deformed by the removal tool during disassembly or assembly, the sharp bending edges 144, 145 first yield and begin to plastically deform, whereby a targeted deformation is achieved in the region of the first section 141, while the third section 143 of the holding means 140 is elastically resilient due to the large angle α 3 and the radius r 3 to the adjoining second section 142.Furthermore, FIG. 2 shows the web 184 adjoining the base plate 103 counter to the installation direction X, with the connecting flange 180 adjoining it.FIG. 3 shows the retaining element described in FIGS. 1 and 2 in the mounted state on the right side 303 of the housing 300 of the built-in device 200. The built-in device 200 is also shown in FIG. 3 after mounting a front panel 210 on a front side 305 of the housing 300 of the built-in device 200. The front panel 210 of the built-in device 200 closes the front side 305 of the housing 300 and is provided with various functional elements, which are not described in any more detail here. In the non-assembled state of the front panel 210 on the housing 300, for example, electronic components such as circuit boards can be inserted into the interior of the housing 300 via the front side 305 of the housing 300.The housing 300 of the built-in device 200 has a cuboidal outer contour in FIG. 3, wherein an upper side 301, a lower side 302, a right side 303 and a front side 305 of the housing 300 can be seen.Through-recesses 211, 212 are formed in the front panel 210 of the mounting device 300 and serve for removing the mounting device 200 from a mounting space of a motor vehicle. In this case, a removal tool, not shown, for example in the form of a wire, is guided through the through-recesses 211, 212 and the installation device 200 is detached from an installation means, not shown here, which is used in the installation space of the motor vehicle.The housing 300 has a receiving element 320 on the outer side, wherein the receiving element 320 is formed here parallel to the installation direction X on the outer side of the housing 300. In an exemplary embodiment, the tongue 130 of the retaining element 100 is inserted and held in the receiving element 320 formed on the right outer side 303 of the housing 300, counter to the installation direction X.FIG. 4 serves for additional clarification and shows the holding element 100 described in FIG. 2 in the mounted state on the housing 300 of the built-in device 200 in a perspective view. The holding element 100 is mounted on the right side 303 of the housing 300.The housing 300 has two recesses on the front 305 in the two opposite corners, via which recesses the retaining element 100 can additionally be connected by means of the first connecting flange 170 and the second connecting flange 180 to the front panel 210 mounted on the front 305 of the housing 300. For this purpose, as shown in FIGS. 3 and 4, a commercially available mounting means 500, for example a screw, is used. As a result, the holding element 100 is secured against being pulled out of the receiving element 320 of the housing 300 in the mounting direction X. The underside of the holding element 100 rests flat on the outer side of the housing 300.Furthermore, the housing 300 has two pins 310, 312 on the front side 305. By means of the pins 310, 312, the respective first connecting flange 170 and second connecting flange 180 are held and centered during the assembly with the housing 300 so that the holding element 300 is arranged parallel to the receiving element 320 formed on the housing 300.The pin can be manufactured integrally with the housing, for example, during an injection molding process. Corresponding to the through-recesses 211, 212 described in FIG. 3 in the front panel 210 of the paving machine 200, the housing 300 has, on the front side 305, on the two opposite sides, the left side 304 and the right side 303, in each case one recess 311, 313 which serves for guiding a removal tool, which is not illustrated. In this case, as shown in FIG. 3, a removal tool, not shown, is guided through the through-recesses 211, 212 in the front panel further through the recess 311, 313 on the front side 305 of the housing 300. The recesses 311, 313 and pins 310, 312 formed on the left side 213 and the right side 214 of the housing 200 are arranged symmetrically here.The same principle applies to the holding means 300, which is not shown here and is mounted on the left side 304 of the housing 300.FIG. 5 shows the system 10 with a holding element 100 and an installation device 200 in the non-assembled state. With the aid of the holding element 300 mounted on the housing 300, on the left side 304 and the right side 303, of the built-in device 200, and the holding means 110, 140 respectively formed on the holding element 100, the built-in device 200 is fixed and held in the installation space of a motor vehicle.Overall, the example shows how a holding element for a housing of an installed device can be formed in a simple manner by the invention, so that the holding means formed on the holding element are not deformed and damaged during disassembly of the installed device. In addition, the examples show a system having such a holding element and a built-in device for installation in a mounting space of a motor vehicle.List of reference characters10 System 100 Holding element 101 Upper side 102 Lower side 103 Base plate 110 First holding means 111 First portion 112 Second portion 113 Third portion 114 First bend 115 Second bend 116 Third bend 119 First latching lug 120 Step 121 Second latching lug 122 Step 123 Tab 130 Tongue 131 Tab 140 Second holding means 141 First portion 142 Second portion 143 Third portion 144 First bend 145 Second bend 146 Third bend 149 First latching lug 150 Step 151 Second latching lug 152 Step 153 Tab 170 First connecting flange 171 Recess 172 Recess 173 Recess 174 First web 180 Second connecting flange 181 Recess 182 Recess 183 Recess 184 Second web 200 Installation device 210 Front panel 211 Through recess 212 Through recess 300 Housing 301 top 302 underside 303 right side 304 left side 305 front side 310 pin 311 recess 312 pin 313 recess 320 receiving element 400 axis of symmetry 500 mounting means X installation direction Y direction to the base plane t thickness material r radius r 2 radius r 3 radius r 4 radius α angle α 2 angle α 3 angle α 4 angle
