[0003] Support element for a motor vehicle body, rear structure and motor vehicle
[0004] The invention relates to a support element for a motor vehicle body according to claim 1. Furthermore, the invention relates to a rear structure for a motor vehicle body according to the preamble of claim 9, as well as a motor vehicle with such a rear structure.
[0005] Rear structures for motor vehicle bodies are already well known from the general state of the art. Such a rear structure typically has at least one side wall which at least partially delimits an interior space, also referred to as the vehicle interior, in the transverse direction of the vehicle. Furthermore, such a rear structure typically has a partition wall, separate from the side wall, which at least partially delimits a rear cargo space in the vertical direction of the vehicle and has at least one attachment point for mounting a hinge device intended for a tailgate.
[0006] The object of the invention is to create a support element for a motor vehicle body, a rear structure for a motor vehicle body and a motor vehicle, so that the tailgate can be attached to the motor vehicle body in a particularly rigid manner.
[0007] This problem is solved according to the invention by a support element for a motor vehicle body with the features of claim 1, by a rear structure for a motor vehicle body with the features of claim 9, and by a motor vehicle with the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent patent rulings and the description.
[0008] A first aspect of the invention relates to a support element for a motor vehicle body, in particular for a rear structure of the motor vehicle body. The motor vehicle body is understood to be the body of a motor vehicle. The motor vehicle is, in case of 24-1159 PIF
[0009] 2. For example, designed as a passenger car. The body is preferably designed as a self-supporting body. The rear structure can be understood, in particular, as a rear section of the vehicle body in the longitudinal direction of the vehicle or the vehicle body. The rear structure can also be referred to as the rear section or rear end. Preferably, the vehicle body, especially in its fully manufactured state, includes the support element.
[0010] The support element has at least one first attachment area, by means of which the support element is to be held or held on a partition wall of the vehicle body, in particular the rear structure, which at least partially, in particular predominantly or completely, limits a rear cargo space of the motor vehicle upwards in the direction of the vehicle height and which has at least one attachment point for attaching a hinge device provided for a tailgate of the motor vehicle, in the area of the attachment point, in particular at least indirectly or directly.This means that the support element is to be held or secured via the first mounting area, in particular at the first mounting area, at least indirectly or directly, on the partition, especially in the installation position of the support element in the vehicle body or on the partition, in the area of the mounting point which is provided or designed for attaching the hinge device intended for the tailgate, wherein the partition at least partially limits the cargo space upwards in the vehicle's vertical direction. In other words, the support element can be attached or is attached via the first mounting area, in particular at least indirectly or directly, to the partition in the area of the mounting point.In particular, the support element can be supported or braced against the partition wall, preferably in the area of the mounting point, via the first mounting area, preferably downwards in the vehicle's vertical direction, and especially at least indirectly or directly. The fact that the partition wall at least partially limits the rear cargo space upwards in the vehicle's vertical direction can be understood to mean, in particular, that the rear cargo space, especially upwards in the vehicle's vertical direction, is at least partially formed or is formed by the partition wall.
[0011] The requirement that the support element is held or is held in the area of the attachment point on the partition wall can be understood in particular to mean that the 24-1159 PIF
[0012] 3. The first fastening area is located in the area of the fastening point, that is, at least in, and especially in the immediate vicinity of, the fastening point.
[0013] The rear cargo area can also be referred to as the rear luggage compartment or trunk. Preferably, the cargo area is designed for storing luggage. This means that luggage can be arranged, or is arranged, in the cargo area; that is, it can be stowed or is stored there. The term "rear-mounted" can be understood to mean, in particular, that the cargo area is located at the rear end of the vehicle body or vehicle in the longitudinal direction.
[0014] The phrase "the attachment point is provided for attaching the hinge assembly intended for the tailgate" can be understood to mean, in particular, that the tailgate is pivotable via the hinge assembly, preferably between a closed position and at least one open position (which differs from the closed position) about a pivot axis, for example, relative to the vehicle body or the partition, and in particular that it is held or held at least indirectly or directly against the partition. In other words, the tailgate is movable at least between the closed position and the open position, for example, about the pivot axis.The pivoting of the tailgate between the closed and open positions can be understood to mean, in particular, pivoting the tailgate from the closed position to the open position and / or from the open position to the closed position, especially around the pivot axis. The hinge mechanism can also be referred to as a tailgate hinge. The tailgate can also be referred to as a trunk lid, rear hatch, or rear door.
[0015] Preferably, in the closed position, a rear opening is closed, for example, completely, by means of the tailgate. This means that, particularly with regard to the open and closed positions, in the closed position the rear opening is covered, in particular completely, by the tailgate. The rear opening can also be referred to as the cargo area opening. In the open position, the rear opening is preferably at least partially, in particular predominantly or completely, uncovered by the tailgate. This means that in the open position the rear opening is not closed or covered. Preferably, the La- 24-1159 PIF
[0016] 4. The cargo area, particularly when the tailgate is in the open position, can be accessed via the rear opening, preferably in the longitudinal direction of the vehicle, into the surrounding area. In the open position, luggage can be arranged in the cargo area via the open rear opening, and thus stowed there. Furthermore, in the open position, luggage stowed or arranged in the cargo area can be removed from the cargo area via the open rear opening. This is not possible in the closed position, which preferably prevents luggage from being arranged or stowed in the cargo area and / or removed from the cargo area in the closed position.
[0017] For example, at least one trim panel is arranged on the partition, particularly on a side of the partition facing upwards in the vehicle's vertical direction, which forms, for example, a parcel shelf at least partially, in particular predominantly or completely. Thus, the parcel shelf can be formed, or be formed, at least partially by the partition via the trim panel.
[0018] Furthermore, the support element has at least one second mounting area, which is spaced apart from the first mounting area, and by means of which the support element is to be held or held on a side wall that at least partially, in particular predominantly or completely, delimits an interior space of the motor vehicle in the transverse direction of the vehicle, in particular outwards, particularly at least indirectly or directly. In other words, the support element can be attached or fastened to the side wall, in particular at least indirectly or directly, via the second mounting area. Again, in other words, the support element can be supported or braced against the side wall element via the second mounting area, preferably outwards in the transverse direction of the motor vehicle, particularly at least indirectly or directly.Furthermore, the partition and the side wall, in particular, can be supported against each other or are supported by the support element. The side wall can be understood to be, in particular, a side frame of the vehicle body. The side wall is designed separately from the partition. The interior, which can also be referred to as the vehicle interior, can be understood to be, in particular, a passenger compartment or passenger cell. For example, the interior is at least partially, in particular predominantly or completely, separated from the 24-1159 PIF.
[0019] 5
[0020] The vehicle body is limited. For example, the side wall limits the cargo space in the transverse direction of the vehicle, especially to the outside, at least partially.
[0021] The invention is based in particular on the following findings and considerations: to prevent, for example, exceptional load cases and / or misuse by a customer of the motor vehicle, it may be desirable to connect the tailgate to the motor vehicle body, especially to the partition, in a particularly rigid manner via the hinge mechanism. For this purpose, it is conceivable in principle to increase the rigidity of an area provided for the connection of the hinge mechanism, i.e., an area of the partition containing the attachment point, for example by, in particular locally, the insertion of an additional, in particular planar, reinforcing plate, which can also be referred to as a local reinforcing plate.However, the resulting increase in stiffness of the connection between the tailgate or the hinge mechanism and the partition may not be sufficient or would require a particularly high sheet thickness of the reinforcing sheet, which would negatively affect the weight of the vehicle body.
[0022] In contrast, the aforementioned disadvantages can be overcome by means of the support element according to the invention. Thus, the support element according to the invention can stiffen the area of the partition wall, also referred to as the connection area, by providing additional support, particularly in the form of a surface, to the side wall. This additional support can be provided by the second fastening area.This means that the support element is connected, or can be connected, to the side wall via the second mounting area, in particular directly, preferably over a surface, whereby the support element rests against the side wall at the second mounting area, in particular directly, preferably over a surface, thereby allowing the partition and the side wall element to be supported against each other by means of the first and second mounting areas, in particular at least indirectly or directly, for example in the transverse direction of the vehicle and / or in the vertical direction of the vehicle. This allows the tailgate to be connected to the body, in particular to the partition, in a particularly stable and secure manner via the hinge assembly. This means that a support to increase the connection stiffness of the tailgate can be achieved by means of the support element according to the invention. Furthermore, the stability of the partition can be particularly improved. 24-1159 PIF.
[0023] 6. This can be increased, which can have a positive effect, for example, on the transport of an assembly that includes at least the partition wall and the side wall element. This allows the manufacturing effort for producing the vehicle body or the vehicle itself to be kept particularly low, especially due to the minimal transport effort required.
[0024] In a further embodiment, it is provided that the first mounting area, particularly in the installed position of the support element in the vehicle body or on the partition, is located a maximum of 70 millimeters, specifically a maximum of 40 millimeters, or a maximum of 35 millimeters, away from the mounting point. In other words, the distance between the first mounting area and the mounting point is a maximum of 70 millimeters, specifically a maximum of 50, 40, or 35 millimeters. This allows the support element to be positioned particularly close to the mounting point, thereby significantly increasing the rigidity of the vehicle body, especially the rear structure, in the area of the mounting point.Thus, the fact that the support element is held or is held via the first fastening area in the area of the fastening point on the partition wall can be understood in particular to mean that the first fastening area is located a maximum of 70 millimeters, in particular a maximum of 50, 40 or 35 millimeters, away from the fastening point.
[0025] In a further embodiment, the support element is provided to have at least one third mounting area, spaced apart from the first and second mounting areas, by means of which the support element can be held, in particular at least indirectly or directly, on the partition. This means that the support element can be attached, in particular at least indirectly or directly, to the partition via the third mounting area. This allows for an additional connection of the support element to the partition, thereby significantly increasing the rigidity of the vehicle body or the rear structure in the area of the partition. This allows the tailgate to be connected to the vehicle body with particular rigidity.
[0026] Preferably, it is provided that the third fastening area, in particular in the installation position of the support element in the vehicle body or the 24-1159 PIF
[0027] 7
[0028] The third mounting area is positioned in the longitudinal direction of the vehicle, in front of the first mounting area, and especially in front of the second mounting area. In other words, the third mounting area extends further forward in the longitudinal direction of the vehicle than the first mounting area, and particularly than the second mounting area. This allows the rigidity of the vehicle body or the rear structure in the area of the partition to be significantly increased, especially because the support element can be connected to the partition at different lengths of the partition via the first or the third mounting area.
[0029] In a further embodiment, the support element is provided to have at least one belt holder attachment area, spaced apart, in particular, from the first and second mounting areas, and preferably from the third mounting area, via which a belt holder intended for a vehicle seat belt can be attached to the support element, in particular at least indirectly or directly. This means that the belt holder can be connected to the support element via the belt holder attachment area, in particular at the belt holder attachment area, for example, at least indirectly or directly. This allows the belt holder to be attached to the partition, i.e., to the vehicle body, by means of the support element.Thus, the support element can fulfill several functions: firstly, the described support of the partition and side wall element, resulting in increased rigidity; and secondly, the attachment or securing of the seatbelt holder to the vehicle body. This eliminates the need for a separate connection of the seatbelt holder to the vehicle body, thereby keeping the weight of the vehicle body and the vehicle itself particularly low. Furthermore, the rigidity of the vehicle body in the rear area can be increased in a particularly weight-efficient manner.
[0030] This allows the tailgate to be attached to the vehicle body, especially the partition, in a particularly weight-efficient and rigid manner.
[0031] The seat belt is specifically designed as a seat belt for a rear row of seats, that is, for a seating arrangement in the rear row. The rear row of seats can be understood to mean, in particular, a row of seats located at the rear of the vehicle in the longitudinal direction, i.e., a rear seat row. This means that the rear row of seats, or 24-1159 PIF
[0032] 8. The seating system is located in or is located in a rear area of the interior. The rear area can be understood to be, in particular, a portion of the interior located at the rear in the longitudinal direction of the vehicle. The seating system can be understood to be, in particular, a vehicle seat. Thus, the seating system is designed, in particular, for seating at least one person. Specifically, the rear row of seats is designed for seating at least one person. Preferably, the belt holder has at least one belt retractor and / or unwinding device by means of which the safety belt can be at least partially retracted and / or unwound. For example, the belt holder is designed as an automatic belt retractor.
[0033] In a further embodiment, the support element has at least one material recess which extends, particularly when the support element is installed in the vehicle body or the vehicle itself, in the longitudinal direction of the vehicle between the first and the third mounting area. In other words, the material recess is arranged at least partially, and in particular predominantly or completely, in the longitudinal direction of the vehicle between the first and the third mounting area. Alternatively or additionally, the material recess extends, for example, particularly when the support element is installed in the vehicle body or the vehicle itself, in the longitudinal direction of the vehicle between the first mounting area and the seat belt anchor point.In other words, the material recess is located at least partially, and in particular predominantly or completely, in the longitudinal direction of the vehicle between the first mounting area and the belt anchor point. The material recess can be understood to mean, in particular, a material cutout, which can also simply be referred to as a recess or cutout. Specifically, the material recess is free of material from the support element. The material recess allows the weight of the support element to be kept particularly low. This preferably also results in a particularly high rigidity of the support element.
[0034] In a further embodiment, it is provided that the first and second fastening areas, and preferably the third fastening area, extend obliquely or perpendicularly to each other. In other words, the first fastening area extends in a first direction and the second fastening area extends in a second direction, which is oblique or perpendicular to the first direction. For example, the third fastening area extends in a third direction, which is particularly 24-1159 PIF
[0035] 9 runs obliquely or perpendicularly to the first and / or second direction. This allows the partition and the side wall element, and in particular the belt holder, to be supported against each other at an angle, i.e., angularly. The support element can thus be positioned at an angle to the partition in order to be as close as possible to the fastening point, for example, a screw connection of the hinge assembly, in order to provide additional support and, in particular, to significantly increase rigidity.
[0036] In a further embodiment, the support element is designed as a single piece. This means that the support element is formed from one piece, for example, a monoblock. Thus, the support element has no separately formed and interconnected components. This allows the support element to be manufactured with particularly low effort. Furthermore, the support element can be designed to be particularly rigid.
[0037] A second aspect of the invention relates to a rear structure for a motor vehicle body. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.
[0038] The rear structure has at least one side wall which at least partially, and in particular predominantly or completely, delimits an interior space, in particular of a motor vehicle comprising the vehicle body, in the transverse direction of the vehicle. Delimitation can be understood, in particular, as delimitation in the transverse direction outwards. Furthermore, the rear structure has at least one partition wall formed separately from the side wall, which at least partially delimits a rear cargo space upwards in the vertical direction of the vehicle and has at least one attachment point for attaching a hinge device intended for a tailgate.
[0039] In order to attach the tailgate particularly rigidly to the rear structure or the vehicle body, especially the partition, the rear structure has at least one support element designed separately from the side wall and the partition, particularly according to the first aspect of the invention. The support element 24-1159 PIF
[0040] 10 has at least one first fastening area by which the support element is held on the partition wall in the area of the fastening point, in particular at least indirectly or directly. Furthermore, the support element has a second fastening area, in particular spaced apart from the first fastening point, by which the support element is held on the side wall, in particular at least indirectly or directly.
[0041] A third aspect of the invention relates to a motor vehicle with a rear structure according to the second aspect of the invention. In particular, the motor vehicle has a body which incorporates the rear structure according to the second aspect of the invention. In particular, the motor vehicle has at least one support element according to the first aspect of the invention. Advantages and advantageous embodiments of the first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the third aspect of the invention, and vice versa.
[0042] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or individually.
[0043] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show:
[0044] Fig. 1 shows a schematic and perspective partial view of a motor vehicle according to the invention;
[0045] Fig. 2 shows a schematic and perspective partial view of a rear structure according to the invention; and
[0046] Fig. 3 shows a schematic and perspective detail view of a rear structure according to the invention. 24-1159 PIF
[0047] 11
[0048] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.
[0049] Fig. 1 shows a schematic and perspective partial view of a motor vehicle 1. Thus, in Fig. 1, the motor vehicle 1 is shown in part.
[0050] The motor vehicle 1 has a motor vehicle body 2, which has a rear structure 3. The rear structure 3 is shown in a schematic and perspective partial view in Fig. 2.
[0051] The vehicle body 2, in particular the rear structure 3, has at least one side wall 4. In the present case, the vehicle body 2, in particular the rear structure 3, has two side walls 4 that are formed separately from one another and spaced apart from each other in the transverse direction 5 of the vehicle, with only one of these side walls 4 being visible in Fig. 1. Each side wall 4 at least partially delimits an interior space 6 of the vehicle 1 in the transverse direction 5 of the vehicle, in particular to the outside. Each side wall 4 can in particular be understood to be a side frame.
[0052] Each side wall 4 is, for example, formed in multiple parts. Each side wall 4 has, for example, a first side wall element 4a and a second side wall element 4b, which is formed separately from the first side wall element 4a. The first side wall element 4a is designed as an inner part, and the second side wall element 4b is designed as an outer part. This means that the first side wall element 4a is positioned further inwards in the transverse direction 5 of the vehicle than the second side wall element 4b. For example, at least one roof element of a vehicle roof of the car body 2 or the vehicle 1 adjoins the side walls 4, particularly upwards in the vertical direction 8 of the vehicle, with the side walls 4 being connected to each other via the roof element.
[0053] Furthermore, the vehicle body 2, in particular the rear structure 3, has a partition 9 formed separately from the respective side wall 4, which at least partially, in particular predominantly or completely, limits a rear cargo space 10 of the vehicle 1 upwards in the vehicle's vertical direction 8. Preferably, 24-1159 PIF
[0054] 12 The rear cargo space 10 extends rearward in the longitudinal direction 11 of the vehicle, in particular at least indirectly or directly, to the interior 6. For example, at least one partition element (not shown in the figures) is arranged in the longitudinal direction 11 of the vehicle between the rear cargo space 10 and the interior 6, which, for example, at least partially limits the rear cargo space 10 forward in the longitudinal direction 11 of the vehicle, and, for example, at least partially limits the interior 6 rearward in the longitudinal direction 11 of the vehicle. As shown in Fig. 2, the rear cargo space 10 is, for example, at least partially limited downward in the vertical direction 8 of the vehicle by a loading floor 12.
[0055] As shown in Figs. 1 and 2, the partition 9 in the exemplary embodiment is formed in multiple parts, in particular in three parts. Here, the partition 9 comprises a base part 13 and two side parts 14, 15, which are formed separately from the base part and, in particular, directly connected to the base part 13. The base part 13 can also be referred to as the middle part. For example, the side parts 14, 15 adjoin the base part 13 on both sides, in particular directly, in the transverse direction 5 of the vehicle. Thus, for example, a first of the side parts 14 is arranged on a first side 16 of the vehicle body 2 or the rear structure 3, and the second of the side parts 15 is arranged on a second side 17 of the vehicle body 2 or the rear structure 3, which is different from the first side 16.Sides 16 and 17 are different sides in the transverse direction 5 of the vehicle, in particular facing away from or opposite each other. For example, a first side wall 4 is arranged on the first side 16, and the second side wall 4 is arranged on the second side 17. In particular, the side parts 14 and 15 are spaced apart from each other in the transverse direction 5 of the vehicle. The partition 9 is preferably designed as a sheet metal part, which is in particular made of metal. Thus, in particular, each side part 14 or 15 is designed as a sheet metal part, which is in particular made of metal.
[0056] Furthermore, the motor vehicle 1 has at least one tailgate 18 which is pivotably mounted on the motor vehicle body 2 between at least one closed position and at least one open position, for example about a pivot axis. At least one hinge device 19 is provided for pivoting the tailgate 18 or for attaching the tailgate 18 to the motor vehicle body 2. In the exemplary embodiment, however, two hinges are provided, particularly in the transverse direction 5 of the vehicle.
[0057] 13 mutually opposed hinge devices 19 are provided, wherein a first hinge device 19 is arranged on the first side 16 and a second hinge device 19 is arranged on the second side 17. For attaching the respective hinge device 19 to the partition 9, the partition 9 has at least one respective attachment point 20, 21. In the exemplary embodiment, the first side panel 14 of the partition 9 has at least one first attachment point 20, in particular several first attachment points 20. The hinge device 19, in particular for attaching the tailgate 18, can be attached to the first side panel 14 via the first attachment point 20 of the first side panel 14 or via the first attachment points 20 of the first side panel 14, for example by means of a screw connection.Thus, the hinge assembly 19 can be screwed to the first side panel 14, particularly directly, at the respective first fastening point 20 of the first side panel 14. Furthermore, in the exemplary embodiment, the second side panel 15 has at least one second fastening point 21, but preferably several second fastening points 21. The hinge assembly 19, particularly for attaching the tailgate 18 to the partition 9, can be attached to or fastened to the second side panel 15 via the second fastening point 21, for example, by means of a screw connection. Thus, the hinge assembly 19 can be screwed to the second side panel 15, particularly directly, at the respective second fastening point 21.
[0058] As shown in Figs. 1 and 2, in this embodiment, each side panel 14, 15 has a through-opening 22, 23. Thus, the first side panel 14 has a first through-opening 22, and the second side panel 15 has a second through-opening 23. The respective hinge assembly 19 can be passed through, or is passed through, the respective side panel 14, 15 at least partially via the respective through-opening 22, 23, in particular to attach the respective hinge assembly 19 to the respective side panel 14, 15.This allows the respective hinge assembly 19 to extend at least predominantly on a side of the partition 9 facing downwards in the vehicle's vertical direction and to be attached via the respective through-opening 22, 23 on a side of the partition 9 facing upwards in the vehicle's vertical direction 8 via the respective fastening point 20, 21 to the respective side panel 15, 16, in particular from above in the vehicle's vertical direction 8. The respective hinge assembly 19 has, for example, 24-1159 PIF.
[0059] 14 at least one respective hinge bracket, which can also simply be referred to as a bracket, wherein the respective hinge bracket extends, for example, in the vehicle's vertical direction 8 below the partition 9. Thus, the respective hinge bracket is, for example, at least partially, in particular predominantly or completely, covered in the vehicle's vertical direction 8 by the partition 9, in particular by the side panels 14, 15.
[0060] As shown in Fig. 2, a frame part 24 is arranged, for example, on the partition 9, in particular at a rear end of the partition 9 in the longitudinal direction 11 of the vehicle. This frame part extends, for example, from the first side part 14, across the base part 13, to the second side part 15 in the transverse direction 5 of the vehicle. The frame part 24 forms, for example, a window frame for a rear window (not shown in the figures), at least partially. The rear window adjoins the frame part 24, for example, forward in the longitudinal direction 11 of the vehicle and / or upward in the vertical direction 8 of the vehicle, in particular directly. Thus, the rear window extends, for example, in the vertical direction 8 of the vehicle at least partially, in particular predominantly or completely, over the partition 9, whereby the partition 9 is preferably at least partially, in particular predominantly or completely, covered by the rear window in the vertical direction 8 of the vehicle.
[0061] Furthermore, as can be seen in Fig. 1, the partition 9 is arranged in the longitudinal direction 11 of the vehicle behind a seating arrangement 25 designed for at least one person, which is located in the interior 6. The seating arrangement 25 is, for example, part of a rear row of seats in the longitudinal direction 11 of the motor vehicle 1. The rear row of seats can also be referred to as the rear seat row. Thus, the motor vehicle 1 has, for example, a front row of seats arranged in the longitudinal direction 11 in front of the rear row of seats, which is located in the interior 6. The front row of seats has, for example, at least one further seating arrangement, different from the seating arrangement 25, for at least one person.In particular, the additional seating arrangement, or the front row of seats, is arranged in a front area of the interior 6 in the longitudinal direction 11 of the vehicle, with this front area being located in front of a rear area of the interior 6 in the longitudinal direction 11 of the vehicle. Specifically, the seating arrangement 25, or the rear row of seats, is arranged in this rear area of the interior 6. 24-1159 PIF.
[0062] 15
[0063] As can be seen in Fig. 1, the body shape of the motor vehicle body 2 corresponds to that of a sedan. This means that the motor vehicle body 2 is designed according to the specifications of a sedan, that is, for the motor vehicle 1 which is designed as a sedan.
[0064] In order to connect the tailgate 18, in particular by means of the respective hinge assembly 19, particularly rigidly to the vehicle body 2, in particular the partition 9, the vehicle body 2, in particular the rear structure 3, has at least one support element 26 that is formed separately from the respective side wall 4 and the partition 9. In the exemplary embodiment, however, two such support elements 26, 27 are provided. This means that the vehicle body 2, in particular the rear structure 3, has two support elements 26, 27 that are formed separately from the respective side wall 4 and the partition 9. A first of the support elements 26 can be referred to as the first support element and the second of the support elements 27 can be referred to as the second support element 27. The support elements 26, 27 are separated from each other in the transverse direction 5 of the vehicle.Preferably, the first support element 26 is arranged on the first side 16 and the second support element 27 is arranged on the second side 17. The first support element 26 is particularly well visible in Fig. 3, in which the rear structure 3 or the vehicle body 2 is shown in a schematic and perspective detail view.
[0065] Each support element 26, 27 has a first fastening area 28 by which the respective support element 26, 27 is held on the partition 9, in particular on the respective side panel 14, 15, in the area of the respective fastening point 20, 21, that is, in particular in the area of at least one of the respective fastening points 20, 21. This means that the first support element 26 is held on the partition 9, in particular on the first side panel 14, in the area of at least one of the first fastening points 20, in particular at least indirectly or directly, by means of its first fastening area 28. Furthermore, the second support element 27 is held on the partition 9, in particular on the second side panel 15, in the area of at least one of the second fastening points 21, in particular at least indirectly or directly, by means of its first fastening area 28.In this case, the first support element 26 rests against the first side part 14 via the first fastening area 28, in particular directly, preferably over a surface. Furthermore, in this case, the second support element 27 rests against the second side part 15 via its first fastening area 28, in particular directly, preferably over a surface. 24-1159 PIF.
[0066] 16
[0067] Each support element 26, 27 further comprises a second fastening area 29, by means of which the respective support element 26, 27 is held, in particular directly, on the respective side wall 4, in particular on the respective first side wall element 4a. Thus, in the present case, the first support element 26 is held, in particular at least indirectly or directly, on the first side wall 4, in particular on the first side wall element 4a of the first side wall 4, via its second fastening area 29. Furthermore, in the present case, the second support element 27 is held, in particular directly, on the second side wall 4, in particular on the first side wall element 4a of the second side wall 4. Preferably, the respective second fastening area 29 rests, in particular directly, preferably over a surface, against the respective side wall 4, in particular on the respective first side wall element 4a.
[0068] The respective support elements 26, 27 increase the stiffness of the component assembly comprising the partition wall 9, the support elements 26, 27, and the side walls 4, particularly in the area of the respective attachment points 20, 21. This allows the tailgate 18 to be connected to the vehicle body, especially to the partition wall 9, in a particularly stable manner via the respective hinge assembly 19. The respective support element 26 enables the respective side panel 14, 15 to be supported by the respective attachment areas 28, 29 on the respective side wall 4. This allows the partition wall 9 to be supported against the respective side wall 4, thereby increasing the connection stiffness of the tailgate 18. This means that the respective area for connecting the hinge assembly 19 of the respective side panel 14, 15, also referred to as the tailgate hinge, can be designed to be particularly stiff.
[0069] This is particularly advantageous due to the multi-part, especially three-part, design of the partition 9. For example, for weight reasons, an overall thickening of the partition 9, and especially of the side parts 14, 15, is not practical. In particular, the support elements 26, 27 allow the wall thickness of each side part 14, 15 to be kept particularly small. This allows the wall thickness of each side part 14, 15 to be very thin. For example, the wall thickness of each side part 14, 15 is less than 2 millimeters, preferably less than 1.5 millimeters, for example, exactly 1.4 millimeters. 24-1159 PIF

[0071] Preferably, the respective first mounting area 28 of the respective support element 26, 27 is arranged at a maximum distance of 70 millimeters, in particular a maximum distance of 50 or 40 millimeters, from at least one of the respective mounting points 20, 21. Thus, a distance 30 extends between the respective first mounting area 28 and at least one of the respective mounting points 20, 21, which is a maximum of 70 millimeters, in particular a maximum of 50 millimeters or a maximum of 40 millimeters, or for example a maximum of 35 millimeters. The respective distance 30 extends, for example, in the longitudinal direction 11 of the vehicle and / or in the transverse direction 5 of the vehicle. The respective support element 26, 27 can therefore be arranged particularly close to the respective hinge assembly 19.
[0072] As can be seen in Figures 1 to 3, the respective support element 26, 27 is arranged on the side of the partition 9 that points upwards in the vehicle's vertical direction 8. In particular, the respective first fastening area 28 is arranged above the partition 9 in the vehicle's vertical direction 8.
[0073] For example, the respective support element 26, 27 is welded to the partition wall 9, i.e., to the respective side panel 14, 15, via the respective first fastening area 28, in particular directly, i.e., connected by means of a respective welded joint. For example, the respective support element 26, 27 is welded to the respective side wall 4, in particular to the respective first side wall element 4a, via the respective second fastening area 29, i.e., connected by means of a respective welded joint.
[0074] In the exemplary embodiment, each support element 26, 27 has a third mounting area 31, which is distinct from the first and second mounting areas 28, 29, particularly in the longitudinal direction 11 of the vehicle. The support element 28, 29 is held, particularly directly, on the partition 9, particularly on the respective side panel 14, 15, by means of this third mounting area 31. Thus, in this case, the first support element 26 is held, particularly directly, on the first side panel 14 via its third mounting area 31, and the second support element 27 is held, particularly directly, on the second side panel 15 via its third mounting area 31. For example, the respective support element 26, 27 is welded to the partition 9 via its third mounting area 31. (24-1159 PIF)
[0075] 18 parts of a respective weld connection. In particular, the respective support element 26, 27 rests against the partition wall 9, i.e., against the respective side part 14, 15, via the respective third fastening area 31, especially directly. This contact is preferably a surface contact.
[0076] In the present case, the respective third fastening area 31 is arranged in the longitudinal direction of the vehicle 11 in front of the respective first fastening area 28, and in particular in the longitudinal direction of the vehicle 11 in front of the respective second fastening area 29.
[0077] In the exemplary embodiment, each support element 26, 27 has a respective belt holder attachment area 32, over which a belt holder 33 provided for a respective seat belt 32 can be attached, in particular directly, to the respective support element 26, 27. The respective seat belt 33 is, in particular, a respective seat belt intended for the rear row. For example, at least one of the seat belts 33 is provided for the seat assembly 25. For example, the respective seat belt 33 can be at least partially wound onto and / or unwound from the respective belt holder 34. Preferably, the respective belt holder 34 is designed as an automatic belt retractor.In this case, the respective belt holder attachment area 32 is arranged in the vehicle's vertical direction 8 above the respective mounting area 31, whereby the third mounting area 31 is at least partially covered from above by the belt holder attachment area 32, particularly in the vehicle's vertical direction 8. This allows the respective belt holder 34 to be attached to the partition 9 via the respective belt holder attachment area 32 and the third mounting area 31, and, in particular, to be supported at least downwards against the partition 9 in the vehicle's vertical direction 8. The respective support element 26, 27 can thus be a mounting part for the respective belt holder 34, whereby the described support can be realized as part of such a component in the form of this mounting part. The mounting part can also be referred to as the "belt holder attachment."
[0078] In this embodiment, the respective first and second fastening areas 28, 29, and preferably the respective third fastening area 31, extend obliquely or perpendicularly to each other. As can be seen particularly well in Fig. 3, the respective support element 26, 27 has a first connecting part 35, via which the respective first and second fastening areas 24-1159 PIF
[0079] 19. The support elements 28 and 29 are connected to each other, particularly directly, wherein the respective first connecting part 35 preferably extends obliquely or perpendicularly to the respective first and second fastening areas 28 and 29. Furthermore, the respective support element 26 and 27 has a respective second connecting part 36, which is spaced apart from the respective first connecting part 35, and through which the respective second fastening area 29 and the respective third fastening area 31 are connected to each other, particularly directly. The respective second connecting part 36 preferably extends obliquely or perpendicularly to the second fastening area 29 and the third fastening area 31. In this case, the respective second connecting part 36 has the respective belt holder attachment area 32.This means that the respective belt attachment area 32 is formed or is formed by the respective second connecting part 36.
[0080] As can be seen particularly well in Figs. 1 and 3, the respective support element 26, 27 in the exemplary embodiment has a respective material recess 37, which extends in the longitudinal direction 11 of the vehicle between the respective first and the respective third mounting area 28, 31 and / or in the longitudinal direction 11 of the vehicle between the respective first mounting area 28 and the respective belt holder connection area 32. Thus, in this case, material of the respective support element 26, 27 forming, for example, the respective connecting parts 35, 36 and the respective second mounting area 29, extends around the respective material recess 37. This allows a connection of the partition 9, the respective side wall 4 and the respective belt holder 34 to be effected by means of the respective support element 26, 27 in a particularly weight-efficient manner, i.e., with particularly good or efficient material utilization.
[0081] Preferably, the respective support element 26, 27 is formed in one piece. This means that, in the exemplary embodiment, the respective fastening areas 28, 29, 31, in particular the respective connecting parts 35, 36 and / or the respective belt attachment area 32, are formed in one piece together.
[0082] As can be seen particularly well in Figs. 2 and 3, for example, the frame part 24 is connected, preferably directly, to the partition 9, in particular to the respective side part 14, 15, at at least one of the respective fastening points 20, 21. This means that at this at least one respective fastening point 4-1159 PIF
[0083] 20 0, 21 both the hinge device 19 and the frame part 24 are attached to the partition, in particular to the respective side part 14, 15.
