Description

Technical Field

[0001] This invention relates to a dashboard bracket for a motor vehicle, the dashboard bracket having a crossbeam that can be inserted into the A-pillars of the motor vehicle body, and to a dashboard bracket device and a method of manufacturing the same. Background Technology

[0002] Instrument panel brackets serve as load-bearing components in motor vehicles for various cockpit functions. One of the main components of an instrument panel bracket is the crossbeam. The crossbeam is part of the vehicle body and extends laterally, essentially horizontally, between the A-pillars in the area below the windshield. The crossbeam has length sections on the driver's side and passenger's side, and is typically supported relative to the front wall of the passenger compartment, i.e., the partition wall between the engine compartment and the vehicle interior, and additionally relative to the vehicle floor.

[0003] The crossbeam serves a reinforcing function within the vehicle body and is used to secure and reinforce the dashboard. In addition to the brackets for the dashboard itself, various brackets are mounted on the crossbeam to hold different vehicle functional components such as longitudinal bars, heating and air conditioning systems, the center console, and / or head-up displays (HUDs).

[0004] A head-up display (HUD) is a display system or device that projects information into the user's field of vision.

[0005] The subject of this invention is a dashboard bracket with a crossbeam having a bracket for fixing a head-up display.

[0006] Document DE 10 200 5 031 357 B4 discloses a motor vehicle and an instrument panel module with a crossbeam for use in the motor vehicle. The crossbeam has a fixing device for connecting a head-up display or its projection device.

[0007] Document DE 10 201 7 007 470 B3 discloses a method for mounting a head-up display onto a modular crossbeam for a dashboard.

[0008] According to document DE 10 200 6 025 386 A1, a vehicle cockpit with a head-up display and a crossbeam is in the prior art, wherein a fixing device is provided for pre-installing the head-up display on the crossbeam and for final installation on another load-bearing body component. The fixing mechanism has a mounting bracket for accommodating the head-up display and for fixing the head-up display to the crossbeam.

[0009] The precise placement and positioning of the head-up display (HUD) within the dashboard or dashboard bracket assembly in a motor vehicle are crucial for meeting required quality characteristics, particularly functional dimensions and assembly specifications. Accordingly, the screw-in or mounting surface of the HUD must be highly precise. Specifically, the HUD's screw-in or mounting surface must have a precise position along the z-axis within the dashboard bracket's reference point system. Furthermore, the tilt angle of the HUD around the y-axis is critical for meeting functional requirements. Additionally, dashboard brackets and dashboard bracket assemblies with integrated HUDs must comply with necessary safety regulations, particularly electrical safety regulations. Summary of the Invention

[0010] Based on the prior art, the technical problem to be solved by the present invention is to provide an instrument panel bracket having a functionally and technically improved mounting bracket for a head-up display on a crossbeam, and to provide an instrument panel bracket device and a method for manufacturing the instrument panel bracket.

[0011] According to the present invention, the technical problem is solved by a dashboard bracket for a motor vehicle having a crossbeam between the A-pillars of a motor vehicle body, the crossbeam having a mounting bracket for a head-up display (HUD), wherein the mounting bracket has a carrier for the HUD, wherein the carrier is fixed to the crossbeam by a support member, and the carrier has a flange section having a mounting opening for fixing the HUD, wherein a non-conductive connecting element is provided in the area of ​​the mounting opening. The technical problem is also solved by a dashboard bracket assembly and a method for manufacturing the dashboard bracket assembly.

[0012] The dashboard bracket for a motor vehicle has a crossbeam that can be inserted between and fixed to the A-pillars of the vehicle body. A mounting bracket for a head-up display (HUD) is arranged on the crossbeam. According to the invention, the mounting bracket has a carrier for the HUD, wherein the carrier is fixed to the crossbeam by a support member. The carrier has a flange section with a mounting opening for fixing the HUD. A non-conductive connecting element is provided in the area of ​​the mounting opening.

[0013] Non-conductive connecting elements are force-locked and / or form-locked to the mounting opening. These non-conductive connecting elements are designed and configured, both in terms of material and configuration, to ensure electrical isolation between the head-up display mounted on or within the carrier and the metal components of the dashboard bracket within the dashboard support assembly. "Non-conductive" or "non-conductive" here means that the connecting elements are made, in particular, of a non-conductive material, or of a material whose conductivity is classified as non-conductive. Importantly, the non-conductive connecting elements ensure electrical isolation between the carrier and the installed head-up display. The head-up display or its housing should not be part of the vehicle body's electrical ground. This requirement is achieved by non-conductive connecting elements that provide electrical isolation between the carrier and the head-up display.

[0014] The mounting bracket includes a support body for the head-up display, which is fixed to the support members. Specifically, the support body is welded between two lateral support members. The support members themselves are joined to the crossbeam using a welding technique. This design allows for accurate adjustment and fixation of the mounting bracket along the z-axis (vehicle vertical axis) during welding. In this way, shape deviations or tolerances of the crossbeam along the z-axis can also be compensated for. Furthermore, the mounting bracket can be correctly positioned and engaged by rotation or tilting about the y-axis. Overall, narrower tolerances are achievable, more specifically, through a reasonable welding technique between the components of the crossbeam and the mounting bracket, and their support members and support bodies.

[0015] To fulfill its function within the dashboard bracket and dashboard bracket assembly, the crossbeam is equipped with various retaining members. These retaining members are made of metal and are fixed to the crossbeam by welding. This welding process causes deformation of the crossbeam and the relative positions of the mounting points for the various functional components, particularly the relative positions of the head-up display (HUD) mount. This welding deformation, as well as unavoidable tolerances during the joining process, is compensated for when the carrier is positioned relative to the support. The sidewalls of the carrier abut against the corresponding adjacent inner side of the support and are joined to the support by welding. Here, the correct position of the carrier within the mount is adjusted so that the position of the HUD does not need to be adjusted later, during, or after assembly.

[0016] A preferred aspect of the invention is that the mounting bracket and, in particular, its carrier body are correctly oriented relative to the support member, especially in the zx plane, and a material-locking engagement is performed between the carrier body and the support member at this terminal position. The support member has abutment or engagement surfaces on its lateral legs, which contact the sidewall of the carrier body on the outer side. The carrier body and the support member are welded in the area of ​​the abutment surfaces.

[0017] The carrier provides a non-conductive connecting element on the mounting flange in the area of ​​the assembly opening and engages with the support. The support itself is advantageously secured by welding before the carrier is engaged with the crossbeam.

[0018] In a preferred embodiment, the fixing bracket is joined between two supports. The supports preferably have a support base whose shape is adapted to the outer contour of the beam. The support base partially surrounds the beam and is engaged with the beam material in a locking manner, particularly by welding.

[0019] The support member preferably has a U-shaped arrangement of tabs and two legs in the horizontal cross-section, particularly in the support base.

[0020] Two support members are arranged axially apart along the longitudinal direction (y-axis) of the crossbeam. Each support member has a connecting piece extending along the x-axis. The legs of the struts are oriented from the connecting piece toward the load-bearing body. The load-bearing body is housed between the support members.

[0021] The support members have a mating surface for the load-bearing body. They are preferably located on the legs, especially on the end sides of the legs. The load-bearing body rests against the mating surface with its sidewalls and the materials lock or close together.

[0022] An advantageous design of the dashboard bracket according to the invention specifies that a positioning element for the head-up display is provided adjacent to at least one mounting opening. The positioning element serves as a mounting aid and facilitates the mounting and alignment, or orientation, of the head-up display within the bracket and dashboard support assembly. The positioning element is preferably designed as a through-hole or aperture, particularly an elongated aperture, adjacent to the mounting opening. Advantageously, the positioning element is formed in or within a region of a non-conductive connecting element. The positioning aid, in the form of a hole, serves to receive a pin disposed on the head-up display, through which the head-up display can be oriented during assembly.

[0023] A flange section is provided at the upper end of the sidewall. The flange section points outward (y-axis) from the sidewall. In a particularly advantageous embodiment, at least one flange section of the carrier has two mounting openings arranged spaced apart from each other along the x-axis (vehicle longitudinal axis). A positioning element, in particular a hole, is provided adjacent to one of the two mounting openings in the flange section.

[0024] Preferably, the non-conductive connecting element is made of plastic. The connecting element may at least partially cover the flange section on its upper and / or lower sides. Furthermore, the connecting element may cover the mounting opening on its inner side. Here, the inner peripheral wall of the mounting opening is covered by or coated with the material of the connecting element.

[0025] Another design scheme specifies that the threaded connection element is integrated into the connecting element. The threaded connection element can be made of the same material as the connecting element itself, or it can be formed as a separate component. The threaded connection element is in particular a nut or threaded sleeve, into which the mounting bolts for mounting the head-up display can be screwed.

[0026] Preferably, the connecting element has a connecting tube body. The connecting tube body is disposed, particularly on the underside of the connecting element, in a continuation of the mounting opening. The connecting tube body and the mounting opening share a common central axis. A threaded connecting element integrated into the connecting element is particularly arranged in the connecting tube body and serves as a support for mounting bolts.

[0027] A particularly advantageous design in practice specifies that the connecting element is implemented in the form of a clip. This connecting element is clipped laterally onto the flange section and surrounds the upper and lower sides of the area of ​​the mounting opening. The connecting element clip is automatically held on the flange section by spring clamping. The connecting element clip may have a locking element, such as a spring-loaded leg with locking lugs that press against a mating surface on the mounting flange or pass through a perforation on the mounting flange. The connecting element clip has a through opening that is flush with the mounting opening. This also applies to positioning elements in the form of holes. The connecting element clip has a perforation that overlaps with the positioning hole.

[0028] In an alternative embodiment of the connecting element, the connecting element is implemented as an injection molded part. Here, the area surrounding the assembly opening in the flange section is encapsulated using a non-conductive material, particularly plastic. The positioning elements adjacent to the assembly opening, particularly the positioning holes, are also encapsulated using injection molding.

[0029] The connecting element can be constructed as a plastic clip with integrated threaded components or a plastic injection-molded encapsulation with threaded components. The threaded components, in particular nuts, are into which mounting bolts for installing and securing the head-up display can be screwed.

[0030] The mounting bolts for or used with head-up displays that are adapted to threaded components or nuts may be constructed to have an electrically insulating coating and / or to be in electrically insulating contact only with the head-up display.

[0031] According to the design of the present invention, the fixing bracket can be adjusted, particularly in the z-direction, when engaged with the support member. This allows for compensation of shape deviations in the crossbeam, especially in the z-direction. Furthermore, tilting about the y-axis can be advantageously compensated for, and the correct position of the fixing bracket can be adjusted. Overall, the present invention ensures that narrower tolerances can be achieved, wherein manufacturing is carried out by welding using standard material-locking processes. This improves cycle time and makes manufacturing more efficient overall.

[0032] The load-bearing body has two sidewalls axially spaced along the longitudinal direction (y-axis) of the crossbeam. The sidewalls are oriented along the vehicle's longitudinal axis (x-axis) and extend transversely to the longitudinal direction of the crossbeam. Between the sidewalls, a longitudinal wall, particularly a rear wall or longitudinal wall bar, extends along the longitudinal direction of the load-bearing body, i.e., along the y-axis, and / or a bottom or bottom section or bottom bar extends on the bottom side of the load-bearing body.

[0033] An advantageous design specifies that the carrier provides a receiving space in which the head-up display can be protectively housed. The receiving body is defined by side walls and at least one longitudinal wall, particularly a rear wall, as well as longitudinal wall rods and / or a bottom rod. The side walls are connected to each other in a bending-resistant manner. This is achieved by at least one longitudinal wall and longitudinal wall rods and / or a bottom rod. This achieves particularly advantageous housing and retention for the head-up display. The carrier can be open on the front or rear side, particularly the front side. This improves the installability and accessibility of the head-up display. The carrier may have front and / or rear longitudinal walls between the side walls, said longitudinal walls having a lower height than the side walls. In particular, a rear wall extends between the rear ends of the side walls, which is lower than the side walls on the z-axis. On the front side, the basin-shaped carrier is substantially open. Longitudinal wall rods extend along the bottom between the side walls, said longitudinal wall rods being implemented as transition sections on the bottom.

[0034] The support members are respectively attached to the side wall of the carrier on the outside and engaged with the material in a locking manner. Positioning aids and / or engagement aids, for example in the form of markings, may be provided on the side wall and / or support members. The markings may be formed by material protrusions, material transition parts, slots and / or through holes or holes.

[0035] The joint area between the sidewalls of the support and the carrier extends in the zx plane. The abutment surfaces, especially those on the legs of the support, can form a common joint area. Alternatively, the abutment surfaces, and therefore the joint surfaces, may be offset in the zx plane. This can be achieved, for example, by using different legs. The legs can also be configured such that the abutment surfaces and therefore the joint surfaces are in positions that are three-dimensionally displaced relative to each other.

[0036] The support has a bottom. Preferably, the support is partially open on the bottom side. This helps to reduce the weight of the support. In particular, the support has a bottom with a receiving portion and / or a through portion and / or an opening, wherein the opening may have a flange surrounding the edge side or a flange section on the edge side.

[0037] The dashboard support assembly has a dashboard support according to the invention and a head-up display mounted on the support.

[0038] The method for manufacturing the dashboard bracket assembly includes the following steps:

[0039] - Provide a metal crossbeam, which is defined and designed for insertion between the A-pillars of a motor vehicle body;

[0040] - Multiple metal support components are connected to the crossbeam by welding, wherein at least two metal supports are fixed to the crossbeam, and the at least two metal supports are designed and defined for connection with the carrier for the head-up display;

[0041] - Provide a carrier for a head-up display, the carrier having two sidewalls arranged spaced apart from each other and connected to each other in a bending-resistant manner;

[0042] - Position the carrier relative to the support member, and align the carrier relative to the support member in the zx plane;

[0043] - The load-bearing structure is connected between the supporting components using welding technology;

[0044] - Provide and install the head-up display in a fixed frame.

[0045] An advantage here is that the carrier is correctly oriented relative to the support members already joined to the crossbeam on the z-axis (vehicle vertical axis) and x-axis (vehicle longitudinal axis), i.e., in the zx plane, and then the material is locked into the support members by welding. This is achieved by a suitable welding device or welding technique. After the components are welded, the mounting bracket is ready to accommodate the head-up display. No further adjustments to the head-up display itself are required.

[0046] A technical solution for improving the functionality of the instrument panel bracket specifies that the crossbeam has a driver-side length section with a crossbeam end, wherein the crossbeam end has a mounting opening that passes through the driver-side length section along the vehicle's longitudinal axis (x-axis) in the region of the crossbeam end. The cross-sectional geometry, along with the crossbeam's fixation on the vehicle's longitudinal axis (x-axis), ensures advantageous mounting of the instrument panel bracket within the vehicle body and advantageous fixation in terms of static and dynamic load characteristics. Particularly advantageously, the crossbeam end has a rectangular configuration in a vertical cross-section, the configuration having a height measured in the vehicle's vertical axis (z-axis) that is greater than the width measured in the vehicle's longitudinal axis (x-axis).

[0063] In the accompanying drawings, the same reference numerals are used for the same or functionally corresponding components or component parts. This also applies to the dimensions and / or specifications shown.

[0064] The terms “upper and lower,” “front and rear,” “horizontal and vertical,” or “longitudinal and transverse,” as well as “upper side and lower side,” “driver’s side,” “driver’s side,” “passenger’s side,” or “passenger’s side” all refer to the installation position of the crossbeam between the A-pillars within the body of a motor vehicle, or the installation position of the bracket on the crossbeam and relative to the crossbeam.

[0065] The vehicle coordinate system is a three-dimensional Cartesian coordinate system used to mark the axes inside the vehicle. The origin of the coordinate system is located in the vehicle's center plane. The x-axis corresponds to the vehicle's longitudinal axis, the y-axis corresponds to the vehicle's transverse axis, and the z-axis corresponds to the vehicle's vertical axis.

[0066] Figure 1 The dashboard bracket 1 is shown. Figure 2 The enlarged diagram shows the data based on... Figure 1 The view of the length section of the dashboard bracket 1 on the driver's side.

[0067] Figure 3 A technically schematic and highly simplified side view of the dashboard bracket 1 is shown.

[0068] The dashboard bracket 1 has a crossbeam 2. The crossbeam 2 can be installed between the A-pillars (not shown) of the vehicle body and extends laterally between the A-pillars in a substantially horizontal direction along the vehicle's transverse axis (y-axis). The crossbeam 2 is secured to the A-pillars by mounting members 3 provided on the end sides of the crossbeam 2.

[0069] The crossbeam 2 is made of steel. Various brackets for vehicle functional components are connected to the crossbeam 2. Guide rod holder 4 and support rod 5 are shown as examples.

[0070] The crossbeam 2 has a mounting bracket 6 for the head-up display 7 (HUD).

[0071] Figures 4 to 7 The first embodiment of the mounting bracket 6 is shown.

[0072] according to Figures 8 to 11 A second embodiment of the mounting bracket 6 for the head-up display 7 is described.

[0073] The mounting bracket 6 includes a support body 8 for the head-up display 7. The support body 8 is preferably basin-shaped. The support body 8 has two side walls 9, 10 arranged spaced apart from each other along the y-axis. A rear-closed rear wall 11 extends between the side walls 9, 10. A bottom 12 of the support body 8 extends along the bottom side between the side walls 9, 10. The bottom 12 is partially open and has a recess 13. A crossbar 14 extends between the two recesses 13 of the support body 8 in this embodiment. The crossbar 14 extends along the x-axis between a rear bottom bar 15 and a front bottom bar 16 (extending along the length of the bottom 12, respectively). The support body 8 is open at the front. The front bottom bar 16 transitions roundedly into a forward-pointing longitudinal wall bar 17. The longitudinal wall bar 17 extends between the side walls 9 and 10.

[0074] The support body 8 has flange sections 19 and 20 on its upper end 18 of the side walls 9 and 10, respectively, pointing outward along the y-axis. The flange sections 19 and 20 extend along the side walls 9 and 10. Mounting openings 21 and 22 are provided in the flange sections 19 and 20. The mounting openings 21 and 22 pass through the flange sections 19 and 20 along the z-axis. The mounting openings 21 and 22 are used to fix the head-up display 7.

[0075] The flange section 19 on the side wall 9 is longer than the flange section 20 on the opposite side wall 10. In the middle length section, a groove 24 is provided in the transition portion 23 from the side wall 9 to the flange section 19. The groove 24 is imprinted outward from the inside of the support body 8 and extends locally on the flange section 19 along the y-axis.

[0076] A positioning element 25 in the form of a hole or elongated hole is provided adjacent to the assembly opening 21 at the rear of the plane of the drawing in flange section 19 and adjacent to the assembly opening 21 in flange section 20.

[0077] Sidewalls 9 and 10 are longer than rearwall 11 on the z-axis, making sidewalls 9 and 10 higher than rearwall 11. At the rear wall end of flange sections 19 and 20, the flange sections transition from sidewall 9 or 10 into rearwall 11 via curved and tapering transition sections 26.

[0078] The load-bearing body 8 is fixed to the crossbeam 2 by supports 27 and 28. Each support 27 and 28 has a support base 29 configured to fit the outer contour of the crossbeam 2. The supports 27 and 28 have U-shaped tabs 30 and legs 31 and 32 respectively turning along the x-axis on the tabs 30 in a horizontal cross-section. The support base 29 stands on the outer periphery of the crossbeam 2 and partially surrounds the crossbeam. Each support 27 and 28 is welded into the crossbeam 2. The supports 27 and 28 taper upward toward the free end or the end 33 on the load-bearing side. The legs 31 and 32 are longer in the area of ​​the support base 29 than at the upper end 33 on the load-bearing side. The supports 27 and 28 have abutment surfaces 34. The load-bearing body 8 abuts against the abutment surfaces 34 of the supports 27 and 28 with its sidewalls 9 or 10 and engages with the supports 27 and 28. During the assembly process, the position of the support 8 relative to the supports 27 and 28 on the z-axis can be adjusted. Orientation of the support 8 at the tilt angle is achieved by rotation about the y-axis. The correct position and location of the fixing frame 6 on the y-axis is achieved by the position of the supports 27 and 28 on the crossbeam 2.

[0079] Non-conductive connecting elements 35 and 36 are respectively arranged in the areas of the assembly openings 21 and 22. Connecting elements 35 and 36 cover the areas of the flange sections 19 or 20 adjacent to the assembly openings 21 and 22 (including the positioning element 25) on their upper and lower sides, respectively. Connecting elements 35 and 36 also electrically insulate the inner periphery of the assembly openings 21 and 22 and the hole walls or interior of the positioning element 25. "Covering" means that connecting elements 35 and 36 rest against the surface of the covered layer, and that connecting elements 35 and 36 line the assembly openings 21 and 22. The non-conductive connecting elements 35 and 36 are designed and arranged to achieve electrical isolation between the mounting bracket 6 and the head-up display 7.

[0080] According to Figures 4 to 8 The described fixture 6 and as per Figures 9 to 13 The difference in the described mounting bracket 6 lies in the implementation of the connecting element 35 or 36.

[0081] according to Figures 4 to 8 The connecting element 35 of the fixing bracket 6 shown in the figure is implemented in the form of a clip 37.

[0082] according to Figures 9 to 12 The connecting element 36 of the bracket 6 shown in the figure is implemented as an injection molded part 38.

[0083] In the design of the clamp 37, the connecting element 35 is made of plastic and has an upper clamping section 39 and a lower clamping section 40, which respectively surround the flange sections 19 and 20. At the ends opposite to the flange sections 19 and 20, the upper clamping section 39 and the lower clamping section 40 are connected by an arc-shaped member 41.

[0084] A connecting tube body 42 extends downward from the lower clamping section 40. The connecting tube body 42 has an elongated opening that forms a continuation of the mounting opening 21. A threaded connecting element 43 in the form of a threaded sleeve (see in particular) is integrated into the connecting tube body 42. Figure 7 and 8 ).

[0085] The clamp 37 has a locking element 44 in the form of a spring-loaded leg, the spring-loaded leg having a locking nose. The locking element 44 passes through an opening 45 in the flange section 19 and the lower clamping section 40 and is abutted against the lower clamping section.

[0086] The connecting element 35, in the form of a clip 37, has a mating surface 46 on its upper side. Mounting elements, particularly bolts, contact the mating surface with their screw heads. The mating surface 46 is lowered or recessed relative to the upper exterior of the connecting element 35. The mating surface 46 surrounds the mounting openings 21, 22.

[0087] like Figures 9 to 13 The non-conductive connecting element 36 shown is made of plastic as an injection molded part 38. The connecting element 36 is respectively constructed in the region of the assembly openings 21, 22 and covers the region of the flange sections 19, 20 on the upper and lower sides. In addition, the inner peripheral walls of the assembly openings 21, 22 and the hole of the positioning element 25 are covered or coated with the injection molded material of the non-conductive connecting element 36.

[0088] The threaded connecting element 43 is also integrated into the connecting element 36. For this purpose, the connecting tube 42 is manufactured on the non-conductive connecting element 36 using injection molding. The threaded connecting element 43, in the form of a threaded sleeve, passes through the connecting element 36 and forms part of the assembly opening 21 (see [link]). Figure 13 ).

[0089] The crossbeam 2 and the mounting bracket 6 or its load-bearing body 8, as well as the support members 27 and 28, are made of steel. The non-conductive connecting elements 35 and 36 are made of non-conductive materials, especially plastic, and are sized in such a way that electrical isolation is ensured between the components of the mounting bracket 6 and the installed head-up display 7.

[0090] Figure 14 Another embodiment of the mounting bracket 6 for the head-up display 7 is shown. The mounting bracket 6 substantially corresponds to the embodiment according to... Figures 3 to 6 The described mounting bracket 6. Therefore, refer to the description there. The load-bearing body 8 is fixed to the crossbeam 2 by supports 27 and 28. A slot 49 extending across the edge 48 is provided in the vertically extending edge 48 at the transition between the connecting piece 30 and the leg 31. The slot 49 reinforces the supports 27 and 28.

[0091] The connecting element 35 used in the fixture 6 or the carrier 8 is implemented in the form of a clip 37, wherein the same type of clip 37 is used on the two flange sections 19, 20 and the assembly openings 21, 22 thereon.

[0092] Figure 15 A dashboard bracket 1 is also shown. The dashboard bracket 1 has a crossbeam 2. The crossbeam 2 can be inserted between the A-pillars of the vehicle body (not shown) and extends laterally between the A-pillars in a substantially horizontal direction.

[0093] The crossbeam 2 has a length section 50 on the driver's side and a length section 51 on the passenger side, which are connected to each other. The length section 51 on the passenger side is formed by a straight-extending tube. The length section 50 on the driver's side is extruded by UO forming of a sheet metal blank.

[0094] The driver's side crossbeam end 52 on the left side of the drawing plane is rectangularly constructed and has a tubular mounting opening 53 that passes through the crossbeam end 52. The crossbeam 2 is threadedly connected to the vehicle body or A-pillar along the vehicle's longitudinal axis (X-axis) via the mounting opening 53 and corresponding mounting elements. The crossbeam end 52 is rectangularly constructed in vertical cross-section and has a height measured in the vehicle's vertical axis (Z-axis) that is greater than its width measured in the vehicle's longitudinal axis (X-axis).

[0095] A welded retainer 54 is additionally provided below the end 52 of the crossbeam on the driver's side, the retainer having a mounting opening 55. The mounting opening 55 is also oriented along the vehicle's longitudinal axis (x-axis) and is used to indirectly or directly fix the instrument panel bracket 1 or the crossbeam 2 to the A-pillar of the vehicle body.

[0096] In the direction of the length segment 51 facing the co-driver's side, the rectangular cross-section transitions to a circular cross-section. In the press forming process of the length segment 50 on the driver's side, the flat metal blank is first formed in a U-shape in cross-section and then formed into an O-shaped or rectangular closed tube. The S-shaped profile curve at the transition from the rectangular cross-section to the circular cross-section is manufactured by UO forming without the need for additional bending operations.

[0097] A straight guide rod section 56 is connected to the S-shaped transition section in the length section 50 on the driver's side. Above the guide rod section 56, a mounting bracket 6 for the head-up display is material-locked together. The mounting bracket 6 is welded to the guide rod section 56 along with the support members 27 and 28.

[0098] A first tunnel support 5 between the driver-side length section 50 and the passenger-side length section 51 of the crossbeam 2, and another tunnel support 5 in the passenger-side length section 51, connect the first tunnel support to the vehicle ground or vehicle tunnel.

[0099] A mounting component 3 is also provided on the end 57 of the A-pillar side of the length section 51 on the passenger side of the crossbeam 2. The mounting component 3 is welded and has an opening 58 on the vehicle's longitudinal axis (X-axis) for threaded connection to the body or the A-pillar thereon.

[0100] Alternatively, additional mounting brackets and struts may be provided, for example for air conditioning systems, steering column fasteners, operating elements, or for the instrument panel itself.

[0101] Furthermore, it can be seen that the driver's side crossbeam end 52 passes through the retaining member 59. Together with the retaining member 60 located at the passenger side end 57 there, it serves to secure the instrument panel.
