Description

Technical Field

[0001] The invention relates to a positioning system for positioning a display device in a motor vehicle, the display device being used to display visually perceptible information, and to a motor vehicle comprising such a positioning system. Background Art

[0002] Elements for equipping the interior of a motor vehicle, including also various display devices and their connection to the load-bearing structure of the motor vehicle, must meet certain design requirements in order to ensure that the risk of injury to the vehicle occupants in the event of an accident is low. The risk is that in the event of an accident, the vehicle occupants may be injured by a head impact on the interior equipment element. There is therefore a requirement to reduce or keep the corresponding risk at a low level. These requirements are met with the help of design standards and standardized tests that simulate such situations and are defined in, for example, the ECE-R-21 regulation.

[0003] For reasons of visual design of the vehicle interior and increased user-friendliness, efforts are increasingly being made to arrange at least partially freestanding display devices with the largest possible display and / or operating surface, for example in the form of displays, in particular in the area of ​​the instrument panel. Freestanding display devices are characterized in that they protrude from the facing of the instrument support, rather than being completely integrated in the instrument support.

[0004] For safety reasons, the freestanding display device and / or the connection to the supporting structure of the motor vehicle is designed to minimize the risk of injury in the event of a head impact.

[0005] From the prior art, various technical solutions are known for arranging display devices in the interior of a vehicle.

[0006] Document CN 1443670 A shows a device for arranging a radio including a display in a motor vehicle. The device enables the display to be moved out of its arrangement plane by at least a partial rotational movement in order to be able to access a device arranged behind the display, such as a tape recorder. The rotational movement is achieved here by means of a rail system.

[0007] Document EP 124093 A1 shows a fixing device for fixing a display device, in particular on a roof element of a vehicle, such as an aircraft, and a method for installing the fixing device. The device comprises a rail system for mounting the device on a vehicle. The display device or the display can be flipped out of the plane on the top of the vehicle so that the user can see the screen of the display device.

[0008] EP 1 538 028 A2 and US Pat. No. 7,712,707 B2 also disclose solutions for moving a screen in a rotational motion to make it available to a user.

[0009] Document WO 2007 / 075461 A2 shows an entertainment system for people in the rear seat of a motor vehicle, which is mounted on the back side of the front seat. The entertainment system comprises a support element and an adjustment mechanism, which enables the display device to be moved. In this case, the system provides not only the possibility of translational movement of the display device but also the possibility of rotation of the display device, in order to optimize the available viewing angle range for the occupants in the rear seat of the vehicle. The support element of the system can be designed to protect the display device by means of a function or an element, which collapses or bends when the display device or the display is subjected to force, in particular when a person grasps and / or pulls the display device or the display.

[0010] In order to reduce the risk of head injuries in the event of an accident, in the prior art, the dashboard in which the display device is embedded is usually designed, for example by material selection, so that the dashboard bends in the event of a head impact. However, such an embodiment may result in vibrations of the vehicle caused by operation being transmitted to the display device, thereby interfering at least with the readability of the displayed information and / or the operation of the display device by the user. Summary of the invention

[0011] The technical problem to be solved by the present invention is to provide a positioning system for positioning a display device, which meets average safety requirements in a simple and cost-effective manner and provides good operability with a wide degree of design freedom.

[0012] According to the invention, this object is achieved by a positioning system for positioning a display device and by a motor vehicle.

[0013] A first aspect of the present invention is a positioning system for positioning a display device, in particular a display, in a motor vehicle, in particular a private car, the display device being used to display visually perceptible information. The positioning system comprises a display device and a guide system. The guide system comprises at least one rail element and at least one slide element that can be guided by the rail element. Here, one of the two elements is fixed to the display device by means of a connecting device, and the corresponding other element is designed to be connected to a supporting structure, in particular to a crossbeam of an instrument bracket of a motor vehicle.

[0014] Elements and / or connections attached to the display device are designed to break when a momentum p1 greater than 42 kg*m / s acts in the first display device region. The first display device region is further away from the guide plane defined by the guide system than a dividing surface extending parallel to the guide plane.

[0015] Furthermore, the positioning system comprises at least one securing element, which is fixedly connected with a first end region to the display device and with a second end region to an element designed for connection to the support structure. The securing element is designed to deform, in particular bend, when a momentum p2 of greater than 42 kg*m / s acts in the second display device region, so that the guide system can achieve a substantially translational movement of the display device by a relative movement of the rail element and the slide element in the guide plane. The second display device region is closer to the guide plane or no further away than a dividing surface extending parallel to the guide plane.

[0016] The positioning system serves to position the display device in a motor vehicle, in particular in the interior of the motor vehicle, in the region where other devices and instruments are usually arranged.

[0017] In the context of the present invention, a display device is understood to be a device capable of displaying visually perceptible information. The display device is designed to enable control and / or reading and display of one or more modules of a vehicle, to which the display device is coupled via information and / or control technology.

[0018] Such display devices are, for example, displays, which generally include a screen for displaying information and / or for inputting control commands and a housing at least designed to accommodate the screen, and generally have an interface for supplying energy to the display device and / or exchanging data with other modules of the vehicle.

[0019] The housing is, for example, substantially made of magnesium. Embodiments in which the housing is substantially made of other metals, alloys and / or plastics are not excluded here either.

[0020] The screen is usually (but not necessarily) a combined or multifunctional input and output device. The screen can be a touch-sensitive screen, for example a touch screen. When the positioning system is arranged as required in a motor vehicle, the screen is oriented toward the vehicle occupant. In other words, the screen is arranged in a screen plane, which is oriented substantially perpendicular to the vehicle floor when the positioning system is arranged as required in the vehicle. The display device, in particular the screen, is thus designed to be read and / or operated by the vehicle occupant.

[0021] The display device or the display including the screen is at least partially free-standing or freely hanging. The free-standing display screen means that the display screen is at least partially arranged in or on the instrument support so that the display screen protrudes from the facing surface of the instrument support.

[0022] The positioning system includes a guide system. The guide system includes at least one rail element and at least one slide element (or slider element). The rail element and the slide element can move relative to each other in a guided relative movement. Usually, the guide system is constructed by a plurality of rail elements and slide elements, wherein usually at least one slide element is configured for the rail element.

[0023] Typically, the guided relative movement is blocked in at least one degree of freedom of rotation and / or translation. In particular, all degrees of freedom of rotation, in particular all degrees of freedom of rotation and at least one degree of freedom of translation, are blocked in the relative movement between the track element and the slide element. In the latter case, all degrees of freedom of rotation and two degrees of freedom of translation are blocked in the relative movement, so that only a relative movement in a two-dimensional plane is possible. In this case, a linear or straight-line guidance is achieved by means of the guide system.

[0024] The guide plane is defined by means of the rail element and the slide element, in which a guided relative movement of the two elements relative to one another can be carried out. Usually (but not necessarily), the guide plane is a two-dimensional vertical plane, so that a linear or straight-line guidance can be achieved by the guide system. However, it is not excluded that the guide plane is at least partially curved, in particular in order to achieve a common guidance of the rail element and the slide element on a curved movement path, for example during assembly.

[0025] The guide system can include a plurality of rail elements. In one embodiment, the guide system includes two rail elements located opposite one another in a common plane, on or in which at least one carriage element can be or is arranged.

[0026] The slide element is designed to be movable in or on a rail element in a guided manner. For this purpose, the slide element can be, for example, a sliding element or a sliding block. At least one sliding surface of the sliding element, which is in mechanical contact with the rail element or is designed for mechanical contact with the rail element, is advantageously provided with a low-friction surface. In particular, the sliding element, however, at least the sliding surface of the sliding element, is made of plastic, in particular of POM (polyoxymethylene).

[0027] In an alternative embodiment, the sliding element comprises at least one rolling body in order to minimize the friction of the relative movement of the sliding element and the rail element with respect to one another.

[0028] In one embodiment, a rail element or rail elements are at least partially implemented as a profile open at least on one side, such as a U-shaped, C-shaped or L-shaped profile. In the inner cavity of the profile defined by the profile wall, the slide element can be introduced or introduced and can be moved.

[0029] In one embodiment, the slide element and / or the track element are equipped with spring elements. The spring elements are designed to achieve tolerance compensation between the slide element and the track element by supporting on other elements, so that the guide system only allows relative movement of the two elements in a guide direction. The spring elements are particularly used to prevent vibrations caused by the operation of the vehicle from being transmitted to the display device and / or to prevent vibration noises from being generated in the positioning system, which is equipped with the positioning system according to the invention. For example, the concavity of the restrictive area of ​​the slide element can be realized elastically.

[0030] The rail element or the slide element is mechanically fixed to the display device, in particular to the housing of the display device, by means of a connecting device. The element not fixed to the display device is designed to be connected to a supporting structure, in particular to a crossbeam of an instrument support of a motor vehicle.

[0031] This means that either the rail element is fixed or fixable on the support structure and the slide element is fixed or fixable on the display device, or the slide element is fixed or fixable on the support structure and the rail element is fixed or fixable on the display device.

[0032] In other words, an indirect mechanical connection between the display element and the support structure is achieved by means of the guide system.

[0033] A load-bearing structure is to be understood as a structural element which is designed so that at least one element of the positioning system according to the invention can be mechanically fastened to it. The load-bearing structure is in particular a cross member of an instrument support. Usually, the instrument support is arranged in the interior of a motor vehicle and is designed to accommodate a variety of different instruments, displays and operating devices, the instrument support being usually the dashboard. The load-bearing structure or the instrument support is fixed or can be fastened to the body of the vehicle.

[0034] The connection device may for example include or constitute a mechanical, in particular frictional and / or form-fitting connection. For example, the connection device includes a screw connection or a riveted connection. However, it is not excluded that the connection between the track element or the slide element and the display device is realized alternatively or additionally by a material connection or an adhesive connection.

[0035] Furthermore, the positioning system according to the invention also comprises a securing element. In one embodiment, the securing element is at least partially implemented as a rod or a plate. Here, the rod or the plate extends substantially parallel to the direction of relative movement between the slide element and the rail element defined by the guide system. The securing element can be, for example, a threaded tab.

[0036] The safety element comprises a first end region and a second end region. The first end region is fixedly connected to the display device. The second end region is fixedly connected to the support structure. The connection can be realized either indirectly or directly. In one embodiment, the fixed connection of the safety element to the support structure is realized indirectly by a mechanical connection between the safety element and an element designed to be connected to the support structure.

[0037] The securing element is designed and / or arranged relative to the display device in such a way that the securing element can be deformed when at least one directional component of the momentum p1 acts perpendicularly in the first display device region of the display device.

[0038] The elements and / or connecting devices fixed to the display device (by means of which the elements to be fixed to the display device are fixed) are designed so that when a momentum p1 greater than 42kg*m / s acts in the first display device area, the elements and / or connecting devices fixed to the display device break.

[0039] In this case, the first display device area is located essentially in the screen plane.

[0040] In other words, the element and / or the connection device attached to the display device is at least partially designed to break in a predetermined manner when subjected to a specific momentum. For this purpose, the element and / or the connection device attached to the display device is provided with at least one predetermined breaking point, for example in the form of a material weakness. The element and / or the connection device attached to the display device is designed to break when subjected to a momentum greater than 42 kg*m / s.

[0041] The fracture is triggered when a force, in particular a shear force, is introduced into the element and / or the connecting device fixed to the display device due to the momentum. The fracture is triggered in particular by applying a force of at least 800 N, in particular at least 1000 N, and particularly in particular at least 1200 N to the element and / or the connecting device fixed to the display device.

[0042] In the context of the present invention, fracture is understood to mean at least partial mechanical destruction of an element and / or a connecting device. At least part of the energy of the momentum p1 is absorbed by the fracture.

[0043] By breaking, at least one further degree of freedom of the display device relative to the support structure is released, which was previously blocked by the guide system. In particular, at least one degree of freedom of rotation is released, so that the display device or at least one region of the display device that is acted upon by the momentum p1 can yield to the momentum p1 in an evasive (or displaced) rotational movement.

[0044] The evasive rotational movement is performed around a rotational axis. The rotational axis of the evasive rotational movement is in a plane parallel to the dividing plane or in the dividing plane itself. In addition, the rotational axis is on the side of the housing of the display device that faces away from the screen plane.

[0045] The axis of rotation extends substantially perpendicularly to the direction of relative movement between the carriage element and the rail element.

[0046] The momentum p1 at which the fracture is achieved is greater than 42 kg*m / s, which corresponds to the test conditions for head impacts according to ECE-R-21, for example.

[0047] The momentum p1 acts in the first display device region. In this case, the first display device region is further away from the guidance plane than an ideal dividing surface extending parallel to the guidance plane.

[0048] The area of ​​the display device which is subject to at least one directional component of the momentum p1 lies substantially in the plane of the screen.

[0049] When the positioning device is arranged as intended in the motor vehicle, the first display device area subjected to momentum p1 faces the seat position of the vehicle occupant. When the positioning device is arranged as intended in the motor vehicle, the first display device area is the upper, in particular free-standing, area of ​​the display device or screen.

[0050] An ideal dividing surface divides the display device area (the momentum acts perpendicularly on the display device area with at least one directional component of the momentum) into a first display device area above the dividing surface and a second display device area below the dividing surface.

[0051] The dividing surface is oriented substantially parallel to the guide plane. In other words, the two planes are substantially equidistant from each other at every point.

[0052] The dividing surface may intersect with the second display device area.

[0053] When a momentum greater than 42 kg*m / s acts in the second display device area and thus in the area below the dividing surface, a basically translational movement of the display device is achieved through the relative movement between the rail element and the sliding element, one of which is connected to the display device.

[0054] In this case, the momentum p2 acts perpendicularly on the second display device area with at least one directional component.

[0055] The deformation of the securing element is achieved by a translational movement. The effect of the momentum p2 in particular leads to bending of the securing element, wherein deformation due to at least partial twisting and / or bending of the securing element is not excluded. The energy of the momentum p2 is at least partially converted into deformation work.

[0056] Due to the deformation of the securing element caused by the momentum p2, the distance between the first end region of the securing element and the second end region of the securing element measured as a projection on the guide plane is reduced. In other words, the distance between the display device and the support structure is reduced due to the translational movement of the display device relative to the support structure. The translational movement of the display device triggered by the action of the momentum p2 can also be referred to as a translational avoidance movement.

[0057] It cannot be ruled out that the action of momentum p1 and / or momentum p2 realizes a rotational evasive movement and an evasive rotary movement of the display device. In other words, it cannot be ruled out that the momentum p1 and / or momentum p2 causes a breakage of elements fixed to the display device and / or the connecting device and a deformation of the securing element, thereby causing the two deflection movements to occur in combination.

[0058] The mechanical connection which fixes the display device relative to the support structure is designed in such a way that it is not destroyed if forces act on the freestanding region of the display device, for example in the form of supporting or gripping the display device.

[0059] Furthermore, the mechanical connection of the display device to the supporting structure is designed to be vibration-damped so that vibrations caused by operation do not lead to perceptible vibrations of the display device, and thus do not make it difficult for the vehicle occupants to read and / or operate the display device due to vibrations.

[0060] A particular advantage of the positioning system according to the invention is that an evasive movement of the display device in the vehicle interior is possible both in the case of a head impact above the dividing surface and in the case of a head impact below the dividing surface, thereby reducing the risk of injury to the vehicle occupant in the event of an accident. The positioning system according to the invention thus enables the use of a particularly large display, which can be arranged at least partially freestanding in the vehicle without the display causing an additional risk of injury.

[0061] In one embodiment, the securing element is designed such that, when the momentum p1 acts in the first display device section, the mechanical connection between the display device and the element provided for connection to the support structure by means of the securing element remains unchanged.

[0062] In other words, even when the indirect connection between the display device and the supporting structure achieved by the guide system is at least partially damaged due to the breakage of components and / or connecting devices fixed to the display device, the mechanical connection between the display device and the supporting structure achieved by the securing element remains unchanged.

[0063] This means that even if the degree of freedom of the display device as a whole which is blocked by the guide system is released due to the momentum p1 , the mechanical connection between the display device and the support structure which is achieved by means of the securing element remains unchanged.

[0064] In other words, the action of momentum p1 will not completely destroy the connection between the first end region and the display device, nor will it completely destroy the connection between the second end region and the element designed to connect to the support structure. However, mechanical weakening of the connection is not excluded.

[0065] The securing element is usually made of metal or an alloy, in particular steel.

[0066] This embodiment has the advantage that the display device cannot completely fall out of the supporting structure in the event of an accident and thus cannot move freely in the passenger compartment.

[0067] In another embodiment, the distance a between the guide plane and the dividing surface perpendicular to the guide plane is proportional to the distance b between the guide plane and the boundary of the display device farthest from the guide plane perpendicular to the guide plane, b / a, wherein b / a>1, in particular b / a>3, and particularly in particular b / a>6.

[0068] In this case, the distances a and b are each to be understood as being measured perpendicularly to the guide plane.

[0069] The position of the ideal dividing surface is optionally determined by a facing element of the instrument support which, at least when acted upon by momentum, bears against the display device, in particular against the rear side of the display device.

[0070] The boundary of the display device farthest from the guiding plane represents the boundary edge or boundary surface of the screen or of the housing region surrounding the screen. Usually (but not necessarily), the screen is oriented substantially perpendicularly to the guiding plane.

[0071] The area of ​​the display device defined by the dividing surface and the boundary of the display device farthest from the guide plane is substantially a freestanding area of ​​the display device, or in other words, an area of ​​the display device that protrudes farthest from the facing of the instrument support.

[0072] The greater the ratio b / a, the further the freestanding area of ​​the display device protrudes beyond the facing from the instrument support.

[0073] The larger the ratio of b / a, the larger the ratio of the first display device area to the second display device area. Accordingly, in the event of an accident resulting in a head impact on the display device, the display device can be avoided by an evasive rotational movement. In other words, in this embodiment, a rotational evasive movement is preferred.

[0074] This embodiment has the advantage that it provides the possibility of independently arranging the largest possible area of ​​the display device, in particular the area of ​​the display device surrounding the screen, in the interior of the vehicle.

[0075] In another embodiment, the slide element is fastened to the display device and the rail element is designed to be connected to a supporting structure, in particular to a cross member of a dashboard of a motor vehicle.

[0076] In this embodiment, the rail element is designed to be fixedly connected to the supporting structure, in particular welded. In addition, in this embodiment, the slide element and / or the connecting device connecting the slide element to the display device is designed to break when subjected to the momentum p1.

[0077] The track element is usually made of metal or an alloy. The track element may comprise a sliding surface intended for low-friction movement of the sliding seat element.

[0078] When the positioning system is arranged as required in a motor vehicle, in other words when it is installed in a motor vehicle, the rail element is usually first fixed to the supporting structure and the display device is subsequently introduced into the space in the motor vehicle designed to accommodate the display device by means of the slide element through an introduction movement relative to the supporting structure.

[0079] In this embodiment, the securing element is connected with its second end region to the rail element and with its first end region to the carriage element.

[0080] When the positioning system is installed in a motor vehicle, the distance between the first end region and the second end region of the slide element determines the final position of the display device relative to the support structure.

[0081] An advantage of this embodiment is the simple installation of the positioning system in the motor vehicle.

[0082] In another embodiment, the securing element comprises at least two arms which are arranged relative to one another in such a way that they define an angle β, wherein 45°<β<180°.

[0083] In other words, the securing element comprises at least one angle, wherein the edge formed by the angle extends perpendicularly to the relative movement of the display device relative to the support structure in the guide plane, so that when the momentum p2 acts on the display device, the angle β decreases. The angled arrangement of the arms pre-bends the securing element.

[0084] The securing element is designed to reduce or further bend the angle β under a compressive load of less than 400 N. If the positioning system comprises a plurality of securing elements, the necessary compressive load per securing element is proportional to the derivative of the number of securing elements, at least as long as the securing elements are oriented substantially parallel to one another.

[0085] Preferably, the angle β is 90° to 180°. Particularly preferably, the angle β is 130° to 150°. In this case, the apex of the angle usually (but not necessarily) points away from the guide plane.

[0086] It can also not be excluded that the safety element comprises more than two arms. It can also not be excluded here that the safety element comprises more than one angle.

[0087] When the momentum p2 acts, at least part of the energy of the momentum is converted into deformation work, ie into deformation of the securing element.

[0088] The advantage is that the evasive movement of the display device triggered by the momentum p2 is not blocked by the securing element, whereas the securing element fixes the position of the display device relative to the support structure in the mounted state.

[0089] In another embodiment, the guide system comprises two mutually spaced slide elements per track element. At least the slide element further away from the first display device area and / or the connecting device further away from the first display device area is designed such that when the momentum p1 acts on the first display device area, the slide element and / or the connecting device breaks.

[0090] The positioning system comprises two slide elements per track element, the two slide elements being spaced apart from each other in a guide plane and along a guide direction defined by the track element. Here, one of the two slide elements is further away from the first display device area than the corresponding other slide element assigned to the same track element. The slide element further away from the first display device area can also be referred to as a rear slide element. The slide element arranged closer to the first display device area can also be referred to as a front slide element.

[0091] The distance between two slide elements, each assigned to a rail element, is at least 30 mm, preferably at least 50 mm, particularly preferably at least 80 mm. At least the slide element further away from the first display device area and / or the connection device further away from the first display device area is designed to break when subjected to the momentum p1, thereby releasing the evasive rotational movement of the display device. It cannot be ruled out that only the slide element further away is connected to the display device by means of a connection device, which is designed to break. In this case, the other slide element serves as a joint.

[0092] The advantage of this embodiment is that the slide element and / or the connecting device closer to the first display device area remains unchanged when subjected to the momentum p1, so that only one rotational degree of freedom of the display device is released after the break.

[0093] In a specific embodiment, the positioning system comprises at least two rail elements. Typically (but not necessarily), the rail elements are arranged laterally on the housing of the display device in a plane perpendicular to the plane of the screen.

[0094] In this embodiment, the positioning system can include two slide elements per track element. The four slide elements are fixed to the housing of the display device by means of a connecting device. The two front slide elements and the two rear slide elements are arranged in pairs with each other. At least the two rear slide elements and / or the rear connecting element are designed to break when subjected to momentum p1.

[0095] In another embodiment, the connection of the securing element to the display device is an articulated connection and / or the connection of the securing element to the element provided for connection to the support structure corresponds to a fixed clamping.

[0096] In other words, the connection between the safety element and the display device is a mechanical connection, which has at least one rotational degree of freedom. In other words, the connection allows a certain degree of play. This can be achieved, for example, by means of a screw connection or an anchor connection.

[0097] In contrast, a fixed clamping is to be understood as a connection in which all translational and rotational degrees of freedom are blocked. This is achieved, for example, by a welded connection.

[0098] In another embodiment, the positioning system additionally comprises an instrument support, which is designed to position the display device in the interior of the motor vehicle.

[0099] In this case, an instrument panel is to be understood as a device for accommodating display and operating devices in the vehicle in front of the driver's seat.

[0100] Generally, within the scope of the present invention, an instrument support comprises a load-bearing structure designed for fastening to a vehicle body and at least one facing element. Within the scope of the present invention, the instrument support may be an instrument panel.

[0101] In another embodiment, at least when the momentum p2 acts and the display device is displaced thereby, at least the instrument support, in particular the molded element of the instrument support, rests partially on the display device. Here, the distance between the areas of the instrument support resting on the positioning system is the distance a between the guide plane and the dividing surface.

[0102] A molded element is understood to be, for example, a facing part.

[0103] At least when the momentum p2 and / or the momentum p1 is acting, the instrument support in the contact area rests on the display device, in particular on the area of ​​the display device facing away from the screen plane. In other words, the instrument support rests on the display device at the back of the screen. The area of ​​the display device that is located above the contact area in the vehicle in a manner consistent with the specification is a free-standing area of ​​the display device. It is not excluded that the instrument support also rests on the display device when no momentum is acting.

[0104] The position of the dividing surface parallel to the guide plane is determined by the contact area. If the instrument support contacts in a planar manner in the contact area, the dividing surface intersects the contact surface at its area centroid. In other words, when the instrument support contacts in a planar manner, the area centroid of the contact surface is used as a basis for determining the distance a.

[0105] Advantageously, the instrument support, in particular at least a region of the instrument support adjoining the display device, is deformable at least when the momentum acts, so that the translational evasive movement of the display device caused by the momentum p2 is not completely prevented by the instrument support.

[0106] A further aspect of the invention relates to a motor vehicle, in particular a private car, comprising at least one positioning system according to the invention for positioning a display device. BRIEF DESCRIPTION OF THE DRAWINGS

When the positioning system 1 is arranged in a motor vehicle as required, the xy plane is a plane that is essentially parallel to the bottom of the vehicle. The x direction corresponds to the extension direction of the longitudinal axis of the vehicle. The y direction corresponds to the extension direction of the transverse axis of the vehicle.

[0114] The positioning system 1 according to the invention comprises a display device 10. In the illustrated embodiment, the display device 10 comprises a screen 12 arranged in a screen plane and a housing 11, which faces the occupants of the vehicle when arranged in the vehicle as required. The screen 12 is integrated into the housing 11 in such a way that the screen is fixed on the housing or in the housing. The display device 10 can also be referred to as a display. The display device 10 is connectable to the vehicle or a module of the vehicle in terms of information technology and / or control technology and for energy supply by means of a first interface 14 and a second interface 15.

[0115] Furthermore, it is shown that the positioning system 1 comprises two rail elements 21. Four slide elements are arranged inside the rail elements 21, of which only the front slide element 222 is shown in the illustrated view. The slide element 222 is mechanically connected to the display device 10 or the housing 11 of the display device 10 by means of a connecting device 30. The rail element 21 is designed to be mechanically connected to a supporting structure, in particular a crossbeam of an instrument support. For example, the rail element 21 can be welded to the supporting structure. The supporting structure is Figure 1 Not shown in the figure.

[0116] The slide element 222 and the rail element 21 together form a guide system. Through a corresponding mechanical connection between the slide element 222 and the display device 10 and between the rail element 21 and the support structure, the guide system enables a guided relative movement between the support structure and the display device 10 in a substantially x-direction. The relative movement takes place in a guide plane defined by the guide system, which extends in the xy plane. Typically, as shown in the figure, the guide system defines a straight line or linear guide using a two-dimensional guide plane.

[0117] Typically, when assembling the positioning system 1, the rail element 21 is first connected to the support structure, in particular welded. Thereafter, the display device 10 connected to the slide element 222 is at least partially introduced into the guide plane defined by the rail element 21 until the final position is reached in the space defined by the instrument support or a section of the instrument support. In this way, the display device 10 is positioned in the vehicle interior.

[0118] Figure 1It is also shown that each of the two rail elements 21 is connected to a respective securing element 40. In the exemplary embodiment shown, the securing element 40 has an L-shape in a top view. The second end region 412 of the securing element 40 is connected to the rail element 21 by means of a welded connection so that the connection is a fixed clamping portion.

[0119] The first end region 411 of the securing element 40 is connected to the display device 10, in particular the housing 11 of the display device 10, by means of a screw connection 44. During assembly, the connection between the securing element 40 and the display device 10 is established after the display device 10 has been introduced by means of the guide system. The position of the display device 10 relative to the rail element 21 is primarily determined and fixed by the screw connection 44. In this way, fixation relative to the instrument support is also achieved at the same time, so that the display device 10 is positioned in the interior of the vehicle and its position in the x-direction is fixed. After the positioning system 1 has been assembled in the vehicle, the first end region 411 is usually concealed by a molded element, in particular a facing element, of the instrument support.

[0120] As shown, each securing element 40 comprises four arms. An angle is formed between the first arm 421 and the second arm 422, between the first arm 421 and the fourth arm 424, and between the second arm 422 and the third arm 423. In other words, the securing element has three bends, wherein the edges formed by the respective bends extend substantially in the y direction and thus extend perpendicularly with respect to the relative movement of the rail element 21 and the slide element 22 along the guide plane.

[0121] Figure 2 Shown in accordance with Figure 1 The design of the side view in the xz plane. The multiple elements of the positioning element 1 are Figure 2 The arrangement 2 relative to one another is the arrangement of the elements relative to one another when positioned in the motor vehicle as intended, without the effects of the momentums p1 and p2 .

[0122] As shown in the drawings, the display device 10 comprises a housing 11 and a screen 12. Also shown is a front slide element 222 which is partially arranged inside the rail element 21 and which together with the rail element 21 forms at least a part of the guide system.

[0123] Figure 2The securing element 40 is also shown. In the view shown, a first arm 421, a second arm 422 and a fourth arm 424 are shown. The third arm is hidden in the view by the rail element 21. An angle β is formed between the first arm 421 and the second arm 422. The angle β is 130° to 150° in the embodiment shown. The bisector of the angle β extends substantially perpendicularly to the guide plane 23. The vertex of the angle β faces away from the guide plane 23. In other words, the securing element 40 forms a bend with the first arm 421 and the second arm 422, the bend pointing away from the guide plane 23 and extending perpendicularly to the direction of the guided relative movement of the rail element 21 and the slide element 22.

[0124] exist Figure 2 Furthermore, a guide plane 23 defined by the guide system and a dividing surface 13 extending parallel to the guide plane are respectively shown in dashed lines.

[0125] The ideal dividing surface 13 divides the display device, in particular the plane of the display device 10, on which the screen 12 is arranged, into two areas, namely a first display device area 131 and a second display device area 132. The position of the dividing surface is essentially determined by the contact area 16. In the contact area 16, the instrument support, in particular the molded element of the instrument support, contacts the screen back 121. The instrument support is not shown here. It should also not be excluded that the contact of the instrument support in the contact area 16 with the screen back 121 is only achieved by an at least partially translational movement of the display device, for example due to momentum.

[0126] If the positioning system 1 does not have an instrument support, the position of the dividing surface is determined by the mechanical connection between the securing element 40 and the display device 10 .

[0127] The housing area of ​​the display device 10 surrounding the screen 12 protrudes significantly beyond the dividing surface 13 and thus beyond the facing of the instrument support in the z direction. In other words, the display device 10, in particular the part of the display device 10 surrounding the screen 12, is essentially free-standing. Here, the vertical spacing a between the guide plane 23 and the dividing surface 13 is usually smaller than the spacing b between the dividing surface 13 and the area of ​​the display device 10 that is vertically farthest from the guide plane 23.

[0128] When the momentum p1 acts on the first display device area 131, the display device 10 yields (or evades) to the acting momentum in such a way that the display device can perform a rotational movement about the rotation axis. The rotation axis about which the evasive rotational movement is performed is essentially located in the contact area 16 and extends in the y direction along or at least parallel to the dividing surface 13. The evasive rotational movement of the display device 10 is achieved in that the momentum is at least partially transmitted to the slide element 21 and / or the connecting device 30 by the display device 10. As a result, at least partial destruction of the slide element 21 and / or the connecting device 30 occurs, so that at least one rotational degree of freedom of the display device 10 can be released and the display device 10 can yield to the momentum p1.

[0129] When the momentum p2 acts on the second display device area 132 and thus in the z direction below the dividing surface 13, a substantially translational evasive movement of the display device 10 in the x direction results. The translational evasive movement is guided by the guide system, so that a movement in the guide plane 23 is achieved. The energy of the momentum p2 is at least partially absorbed by the securing element 40 in that the angle β is reduced by the translational evasive movement of the display device 10 in the x direction.

[0130] Figure 3 Shown in accordance with Figure 1 and Figure 2 A rear view of the design of the positioning system 1 according to the invention in the yz plane. In the view, the screen back side 121 of the display device faces the observer. Figure 1 Correspondingly, the first interface 14 and the second interface 15 of the display device 10 are also provided here.

[0131] Figure 3 It is shown that the rail element 21 forms a profile open on one side at least partially on its side facing the housing 11 in cross section, in which the slide element 223 is arranged. Due to the limitations of the view, only the rear slide element 223 is shown here. The front slide element is arranged in the rail element 21 in a similar manner in the guide plane. The connection device 30 between the housing 11 of the display device 10 and the slide element 233 is also shown. The securing element 40 is also shown in this view.

[0132] Figure 4 A perspective view of the positioning system 1 according to the invention is shown after the momentum p1 acts on the first display device area 131. Figure 2 Compared to the illustration, the position of the display device 10 relative to the guidance plane 23 defined by the guidance system can be changed by a substantially rotational evasive movement of the display device 10 .

[0133] Of the four slide elements 222, 223 present in this embodiment, the front slide element 222 is clearly shown, which is at least partially arranged inside the rail element 21 facing the observer. The second front slide element 222 is arranged in a similar manner in the opposite rail element 21, which is located at the bottom of the rail element 21. Figure 4 The view of the display device 10 is basically blocked by the housing 11 of the display device 10.

[0134] Likewise clearly shown is the rear carriage element 223. A second rear carriage element 223 is arranged opposite, but is completely concealed by the rail element 21 facing the observer.

[0135] and Figures 1 to 3 In contrast to the figure, the rear slide element 223 has no connection to the display device 10 by means of the connection device 30. The action of the momentum p1 on the positioning system 1 will result in at least partial destruction or breaking of the connection device 30, which will lead to an evasive rotational movement of the display device, by means of which the display device will evade under the momentum p1.

[0136] As shown, the securing element 40 is also connected to the rail element 21 in the second end region 412 by means of a welded connection 43. Furthermore, the display device 10 is also connected to the securing element 40 in the first end region 411 after the action of the momentum p1 by means of a screw connection 43. Even if the momentum p1 causes all four connections between the guide system and the display device 10 to break or be destroyed, the connection achieved is maintained unchanged by means of the securing element 40. In other words, the securing element 40 ensures the mechanical connection of the display device 10 to the support structure even when all translational and rotational degrees of freedom of the display device 10 are released due to the destruction of the connection between the guide system and the display device 10.
