Loading floor arrangement for a motor vehicle and trunk with such a loading floor arrangement

Description

[0001] The invention relates to a loading floor arrangement for a motor vehicle with a rigid floor element comprising a cover surface for covering a trunk recess and support surfaces, wherein the support surfaces are operatively connected to contact surfaces that at least partially enclose the trunk recess, wherein the floor element comprises at least two floor sections, wherein a first floor section is pivotably connected to a second floor section by means of hinges about a transverse axis of the motor vehicle, wherein mutually facing end faces of the floor sections have engagement surfaces which have a reduced cross-sectional height, such that the floor sections interlock with each other while maintaining the cross-sectional height of the floor element, wherein, at least when viewed in the vertical axis of the motor vehicle, the first engagement surface arranged above the second engagement surface has a rounding in its end region directed towards the second engagement surface.wherein the engagement surfaces are continuous. The invention also relates to a trunk with such a loading floor arrangement.

[0002] Such load floor arrangements are well known in the art. They serve to cover a trunk recess beneath the actual load floor. This trunk recess can hold small items such as cables, tools, or personal belongings, eliminating the need to place them in the actual trunk. Furthermore, the floor element of the load floor arrangement must be sufficiently rigid to easily withstand the weight of a full load in the trunk. Additionally, the floor element must be designed to ensure easy access to the trunk recess for the vehicle user. A load floor arrangement that meets these various requirements is known from European patent EP 3 046 809 B1.To ensure easy opening of the trunk recess while maintaining high load-bearing capacity of the floor element, the opposing end faces of the floor sections feature a number of interlocking teeth, with one upper tooth having a rounded edge for easy adjustment. Such a loading floor arrangement is relatively complex to manufacture and assemble, and is therefore expensive. Furthermore, a similar loading floor arrangement is known from German patent application DE 10 2018 208 345 A1, in which only one lower half of each of the two floor sections has an engagement surface, which is covered by a continuous end face of the upper half. This design of a loading floor arrangement is also very complex and therefore expensive to manufacture.In contrast, KR 101 997 368 B1, JP 2011 056983 A and JP 2008 247167 A show continuous, interlocking engagement surfaces on both bottom sections, according to the preamble of claim 1. However, stiffness occurs when pivoting a section of the floor. The object of the invention is therefore to avoid the aforementioned disadvantage in a simple way.

[0003] This problem is solved by the features of claim 1, wherein the engagement surfaces are provided exclusively in the area of ​​the cover surface of the floor element, and wherein the bearing surfaces rest on the contact surfaces. This significantly reduces manufacturing and assembly costs. Easy opening with high load-bearing capacity of the floor element is also ensured in this design. Furthermore, pivoting the floor sections relative to each other is made even easier. Since the bearing surfaces interact with the contact surfaces that enclose the trunk recess, sufficient stability of the floor element is guaranteed. It should be clear that instead of two, more floor sections can be provided that can be pivoted relative to each other.

[0004] In a particularly advantageous embodiment, the hinge means are formed as part of a textile upper layer arranged on the floor element. This gives the cargo space arrangement a very high-quality appearance, while the hinge means are implemented in a particularly simple manner. In a further, particularly advantageous embodiment, the floor sections each have a sublayer that is rigid, at least in the area of ​​the overlapping engagement surfaces, with the second engagement surface resting on the sublayer of the first engagement surface. This further increases the rigidity of the floor element in the area of ​​the hinge means.Because the second engagement surface has a rounded edge on the side facing away from the first engagement surface, it is also easy to pivot the second floor section relative to the first floor section, for example from inside the vehicle.

[0005] The task is also solved by a trunk with such a loading floor arrangement, wherein contact surfaces are provided that enclose a trunk recess and that interact with corresponding support surfaces of the floor element.

[0006] The invention is explained in more detail with reference to a drawing, which shows: Fig. 1 a perspective rear view of a motor vehicle with the trunk open, Fig. 2 a top view of a loading floor arrangement according to the invention, Fig. 3 a sectional view according to section AA in Figure 1 and Fig. 4 a sectional view according to section BB from Figure 1 .

[0007] Figure 1 Figure 1 shows a perspective rear view of a motor vehicle 2 with an open trunk lid 4, revealing the trunk 6 of the motor vehicle 2. A loading floor arrangement 8 is provided in the trunk 6, of which a rigid floor element 10 is shown here, comprising two floor sections 14, 16 connected by hinge means 12. The floor element 10 is shown here transparently, indicating a trunk recess 18, which is covered by a cover surface 20 (see Figure 1). Figure 2 ) is covered.

[0008] Figure 2 Figure 8 shows a top view of the loading floor arrangement 8 according to the invention. For the sake of clarity, a textile top layer 22 has been omitted from this view. The textile top layer 22 is present in both Figure 3 as well as in Figure 4illustrated. Their function as hinge means 12 will also be explained in more detail in connection with these figures. As already mentioned in connection with Figure 1 As indicated, the base element 10 has a cover surface 20 for covering an underlying trunk recess 18. The recess 18 is indicated by a dashed line. The recess 18 is bounded by contact surfaces 24, 26, 28, 30. These contact surfaces 24, 26, 28, 30 are naturally located on the side of the dashed line facing away from the trunk recess 18. In addition to the cover surface 20, the rigid base element 10 has support surfaces 32, 34, 36, 38, 40, 42, which rest on the contact surfaces 24, 26, 28, 30. The base element 10 is also connected to the contact surface 28 by means of releasable clips 44.

[0009] To allow easy access to the trunk recess 18, the floor element 10 has two floor sections 14 and 16, which are pivotably connected to each other via hinges 12. Floor section 14 can be easily lifted by grasping a recess 46. Floor section 16 can also be lifted from inside the vehicle by releasing the clips 44.

[0010] The structure of the base element 10, and in particular the structure of the two base sections 14 and 16, will now be described using the following: Figures 3 and 4 explained in more detail. Figure 3Figure 1 shows a sectional view of the floor element 10 in the area of ​​section AA. The textile top layer 22 is clearly visible, forming the hinge means 12 in the area of ​​the opposing end faces 48, 50. The end faces 48, 50 each have engagement surfaces 52, 54 extending along the transverse axis of the vehicle. These engagement surfaces 52, 54 have a reduced cross-sectional height compared to the floor sections 14, 16, such that the floor sections 14, 16 can interlock while maintaining the cross-sectional height of the floor element 10. The engagement surface 52 is positioned above the second engagement surface 54 when viewed along the vertical axis of the vehicle. This design ensures the rigidity of the entire floor element 10 despite the hinge means 12 in the area of ​​the cover surface 20.To ensure easy pivoting of the first floor section 14 relative to the second floor section 16, the first engagement surface 52 has a rounded edge 56 at its end, directed towards the second engagement surface 54. Furthermore, floor sections 14 and 16 each have a sublayer 58, 60, which is rigid at least in its respective end region. In floor section 14, the sublayer 58 extends over the area of ​​the overlapping engagement surfaces 52 and 54. It is advantageous for the rigidity of the floor element 10 if the second engagement surface 54 rests on the sublayer 58 of the first engagement surface 52. To facilitate easy pivoting of the second floor section 16, the second engagement surface 54 also has a rounded edge 62 on the side facing away from the first engagement surface 52.

[0011] Figure 4 now shows a sectional view of section BB in Figure 2Here, the end faces 48, 50 of the floor sections 14, 16 have no engagement surfaces. This is because the rigidity of the floor element 10 is ensured by bearing on the respective support surfaces 34, 36, 40, 42. Only rounded edges 64, 66 are provided, which allow for easy pivoting.
