Description

[0001] The invention relates to a rear compartment floor structure of a motor vehicle, comprising the features specified in the preamble of claim 1.

[0002] Such a rear compartment floor structure of a motor vehicle, as described in DE 197 41 152 A1, features an open-topped wheel well in the floor of the vehicle's luggage compartment, which can be closed flush by a luggage compartment panel. A spare wheel, for example, can be located in the wheel well. If a vehicle wheel is defective, it can be replaced by the spare wheel and placed in the wheel well. The luggage compartment panel is detachably connected to the floor of the luggage compartment via a connecting element, such that if a defective vehicle wheel is located in the wheel well, the luggage compartment panel is positioned in a raised, non-flush position above the vehicle wheel. If the spare wheel is only available as an optional extra or additional feature that is not desired, items can still be carried in the wheel well in the luggage compartment, but these items may only have a cross-sectional shape corresponding to the cross-section of the wheel well.The interior spaces of the vehicle adjacent to the wheel well in a horizontal plane are covered from above by the floor of the luggage compartment and are therefore not usable for the variable storage of objects or components. Fixed installations can only be arranged in these theoretically usable interior spaces if they fit within the limited space, both in volume and shape.

[0003] Furthermore, DE 102 44 768 A1 shows a container with a lid for a motor vehicle trunk.

[0004] Furthermore, DE 20 2006 010 896 U1 shows a multifunctional storage compartment in the trunk of a motor vehicle for a spare wheel with a lid.

[0005] Furthermore, JP 2010-158 970 A shows a trunk for a motor vehicle with a recess for a spare wheel. A lid is provided that forms the floor of the trunk.

[0006] Furthermore, DE 199 48 647 A1 shows a storage box of a trunk above a floor panel with a cover.

[0007] Furthermore, DE 298 10 334 U1 shows a receiving container for a trunk of a motor vehicle with lid elements.

[0008] Furthermore, US 2010 / 0 127 032 A1 shows a tray recessed into the trunk floor with a cover.

[0009] Finally, WO 01 / 02 217 A1 shows a recording compartment in a trunk with two lids.

[0010] The invention is based on the objective of creating a rear floor structure for a motor vehicle that enables better variable use of the luggage compartment of a motor vehicle and has a simpler design.

[0011] This problem is solved by the features in claim 1. Advantageous embodiments of the invention can be found in the dependent claims.

[0012] The rear floor structure of a motor vehicle includes a receiving space into which at least one object is to be inserted via an upper opening. The receiving space is formed by a separate container, which is positioned on a floor wall of the motor vehicle and is detachably fixed to the floor wall and / or wall sections of the motor vehicle by means of a force-fit and / or form-fit connection.

[0013] The container, when not needed in the vehicle, can be removed from the rear compartment at any time after releasing its force-fit and / or form-fit fastening and placed or stored in any desired location. This maximizes the vehicle's rear compartment space, allowing for a variety of uses, such as for storing larger items or luggage. When the container is in place, smaller items or luggage can be recessed within it. It is also possible for at least one item placed in the container to protrude above the top opening.The container can have any cross-section suitable, for example, for receiving a vehicle wheel or spare wheel, and any height, which is dimensioned, for example, such that a vehicle wheel or spare wheel can be completely recessed in the container. It can also be provided, for example, that a spare wheel is recessed in the container and, after a damaged vehicle wheel has been replaced by the spare wheel, the damaged vehicle wheel, which was inserted into the container from above, protrudes upwards above the upper opening of the container. According to the invention, the upper opening of the container is at least partially or preferably completely covered by a removable wall section. Furthermore, according to the invention, after the container has been removed, for example, from the motor vehicle, the wall section is to be positioned on the floor wall of the motor vehicle and detachably fixed to the floor wall and / or wall areas of the motor vehicle by means of a force-fit and / or form-fit connection.The wall section, which is detachably fixed to the floor wall and / or wall sections of the vehicle, can, for example, at least partially cover a recess in the floor wall in which various components or devices of the vehicle, such as electronic equipment, may be located. A retaining element may be attached or be attached to the bottom of the container, with which an object, such as a vehicle wheel or spare wheel, placed at least partially inside the container, can be fixed directly or with the aid of a connecting element, either within or to the container. Displacement of the container placed inside the vehicle must be prevented by simple measures, such as a force-fit and / or form-fit fixing device.For example, forward movement of the container in the rear of the vehicle in the longitudinal direction can be prevented by a front support wall section of the vehicle body or by at least one front intermediate section located immediately behind it, and rearward movement by at least one intermediate section located between the container and a rear support wall section of the vehicle body or a rear intermediate section located immediately in front of it. Alternatively or additionally, the container can, for example, have forward-projecting tabs that, in the installed position of the container, engage a support wall section on the vehicle's floor panel and / or, for example, rest against it from behind. The container can be ordered as optional equipment or accessories, or it can be omitted. In all cases, the rear of the vehicle remains optimally usable without any significant modifications.If the container is not ordered as optional equipment or accessories, it is preferably provided that the wall section is arranged on the floor of the vehicle and detachably fixed to the floor and / or wall sections of the vehicle by means of a force-fit and / or form-fit connection. The wall section can preferably cover a large portion or the entire floor area of ​​the rear compartment, ideally in a flush manner. If the container is purchased as optional equipment or accessories and is arranged, for example, between at least one front and / or at least one rear intermediate section in the luggage compartment of the vehicle, it can be at least largely or completely covered by the wall section previously arranged on the floor area of ​​the rear compartment. For this purpose, the wall section can be fixed at different heights in the luggage compartment of the vehicle, adapted to the respective loading status of the container, by means of a force-fit and / or form-fit connection.

[0015] In Fig. Figure 1 shows a simplified representation of the rear floor structure of a motor vehicle with the tailgate open. Optional equipment available for the vehicle is shown in Fig. 1 not yet installed in the motor vehicle, with which, for example, a spare wheel can be carried in the rear compartment of the motor vehicle.

[0016] The rear compartment of the motor vehicle has a floor wall covered by a removable wall section 1 and a narrow, small wall section 2 located in front of it. In the Fig. In the normal installation position shown in Figure 1, the wall section 1 is detachably fixed in the rear compartment by a retaining device (not shown) by means of a force-fit and / or form-fit connection. The small wall section 2, arranged horizontally flush in front of wall section 1, is fixed in place in the rear compartment and extends forward, for example, at least as far as the rear vehicle seats. The normal direction of travel of the vehicle is indicated by an arrow F. Lateral longitudinal members 3, 4 run alongside wall section 1 and the small wall section 2, essentially in the longitudinal direction of the vehicle. In this embodiment, rear seats 5, 6, 7 are arranged in a rear row in front of the rear compartment; these seats can be individual seats or a one- or multi-section rear bench seat. In the present embodiment, the lower rear area of ​​the rear compartment is bounded by a rear wall 8, which at least partially defines an edge area 9 of a rear opening.The rear opening can be closed by a tailgate (not shown).

[0017] To the in Fig. The motor vehicle shown in 1 can be the one described in Fig. The optional equipment shown in Figure 2 can be ordered, which has a receiving compartment 10 in a separate container 13. The spare wheel 12, marked by cross-hatching, is fully recessed into this compartment via an upper opening 11. After removing the wall section 1 previously attached to the floor wall of the rear compartment of the vehicle, the container 13 can be covered by the wall section 1 and can be detachably fixed to the floor wall and / or wall areas of the vehicle by means of a force-fit and / or form-fit connection.

[0018] The upper opening of the container 13 can be at least partially covered by the wall section 1, which was previously detached from the bottom wall and is arranged in a correspondingly elevated position above the container 13 after the container 13 has been placed in the rear compartment and is fixed in a force-fit and / or form-fit manner.

[0019] In order for the wall part 1, which is arranged in an elevated position above the container 13, to be positioned in a longitudinal vehicle position in the exemplary embodiment with backrests 14, 15, 16 inclined obliquely upwards and backwards, in which the front edge of the wall part 1 can be located close behind the backrests 14, 15, 16 of the rear seats and the rear edge of the wall part 1 is arranged in approximately the same longitudinal position in the longitudinal direction of the vehicle as the longitudinal position of the rear edge of the wall part 1, when the wall part 1 is arranged directly above the floor wall and is fixed by force and / or form locking, the small wall part 2 is located in front of the wall part 1, which, for example, borders at least indirectly on the lower area of ​​the backrests 14, 15, 16 of the rear seats from the rear.

[0020] In the exemplary embodiment, the wall part 1, which is detachably fixed to the floor wall and / or wall areas of the motor vehicle, covers as shown in Fig. 1 shows a floor wall located below and the one in Fig. 5 recognizable depression 17 in the floor wall 18 of the rear compartment completely or at least partially, which in the embodiment has its greatest extent in the transverse direction of the vehicle.

[0021] As in the Fig. 5 and Fig. Figure 6 shows a retaining element 20 attached or to be attached to the bottom 19 of the container 13, with which a vehicle wheel or spare wheel 12, at least partially inserted into the container 13, is to be fixed in or on the container 13, either directly or by means of a connecting means connectable to the retaining element 20. While the container 13 is in Fig. 5 is placed in the rear compartment of the motor vehicle in its transport position, shows Fig. 6 the container 13 as a separate component, from which, for example, simplified details can be taken.

[0022] In the exemplary embodiment, the container 13 has two [parts] on its bottom 19. Fig. Six front tabs 21, 22 and three rear tabs 23, 24, 25, simplified by a broken outline, are shown, each with a lateral distance from the other. When the container 13 is detachably fixed to the floor wall 18 of the rear compartment, the tabs 21, 22, 23, 24, 25 each engage an associated support wall area (not shown) on the floor wall 18 of the vehicle. These support wall areas, or other support wall areas on the floor wall 18, are designed such that, in conjunction with an associated tab 21, 22, 23, 24, 25 or an associated counter-support wall area of ​​the container 13, they prevent the container 13 from shifting forward.

[0023] In this embodiment, the rear tabs 23, 24, 25 each have a U-shaped section in cross-section with a free tab leg 26, 27, 28 projecting downwards and forwards. When the container 13 is detachably fixed to the bottom wall 18, this free leg engages a flange (not shown) on the bottom wall 18 of the vehicle. This flange projects backwards and engages between the legs of an associated U-shaped section of the tabs 26, 27, 28. In this embodiment, the flange projects backwards at the front upper edge of the recess 17 in the bottom wall 18 of the rear compartment of the vehicle.

[0024] Rearward displacement of the container 13, which is installed in the motor vehicle, is achieved by two laterally connected, adjacent components. Fig. 2, 4 and 7 to 9 shown containers 29, 30, which are arranged in the longitudinal direction of the vehicle between the container 13 and the rear wall 8 of the body of the motor vehicle.

[0025] Two front sideways, in the Fig. The intermediate parts 31, 32 shown in Figures 2 and 4 to 6 are integrally connected to the container 13 and thus also in the transverse direction of the vehicle. They form the front corner regions of the container 13 and, at their upper ends, a support surface for the wall section 1 arranged above them. The front intermediate parts 31, 32 each have a vertical wall region 34, 35 that is convexly curved about a vertical axis 33 in a circular-cylindrical segment, the axis 33 being formed by the retaining element 20 located in a central region at the bottom of the container 13.

[0026] The rear intermediate parts 29, 30 are, in the exemplary embodiment, as shown in the Fig. 2 and Fig. 4 are shown arranged laterally side by side and each formed with vertical circumferential walls in a frame shape. Vertical circumferential wall sections 36, 37 of the rear intermediate sections 29, 30 are convexly curved in a circular cylindrical segment shape around the vertical axis formed by the retaining element 20. The vertical wall sections 34, 35 of the front intermediate sections 31, 32 and the vertical circumferential wall sections 36, 37 of the rear intermediate sections 29, 30 are arranged such that they have an approximately equal distance from the running surface of a spare wheel 12 or vehicle wheel placed in the receiving space of the container 13, which is arranged concentrically around the axis 33 of the retaining element fixed to the bottom of the container 13.

[0027] The two rear intermediate sections 29, 30 are, for example, connected in the transverse direction of the vehicle via the Fig. 7 and Fig. The nine simplified connecting elements 41 to 44 are detachably connected to one another by means of force-fit and / or form-fit. A bottom part 38 or 39 is connected to the vertical circumferential walls of the rear intermediate parts 29, 30 in such a way that an open-topped receiving compartment is formed in the respective rear intermediate part 29 or 30. In this embodiment, the rear intermediate parts 29, 39 each have an overlapping wall 45, 46 on their outer sides, which, for lateral fixation, extends over and laterally behind, for example, the upper areas of the lateral longitudinal beams 3, 4 or other wall areas.

[0028] When a vehicle wheel or spare wheel 12 is placed in container 13, the bowl of the vehicle wheel or spare wheel 12 can be filled, for example, as in the Fig. 2 and Fig.Figure 4 shows a small parts container 40, open at the top, which is to be recessed and secured in the well of the vehicle wheel or spare wheel 12 by means of a force-fit and / or form-fit connection. In this embodiment, the small parts container 40 has a central through-opening through which the small parts container 40 is to be attached to the vehicle wheel or spare wheel 12 or to the container 13 in the well by means of the retaining element.

[0029] The invention can, of course, be implemented in ways that deviate from the single embodiment. The rear floor structure of a motor vehicle has a receiving space into which at least one object is to be inserted via an upper opening. The receiving space is formed by a separate container, which is to be arranged on a floor wall of the motor vehicle and is detachably fixed to the floor wall and / or wall sections of the motor vehicle by means of a force-fit and / or form-fit connection. The upper opening of the container can be at least partially covered by a detachable wall section. For example, after the container has been removed, the wall section can be arranged on the floor wall of the motor vehicle and detachably fixed to the floor wall and / or wall sections of the motor vehicle by means of a force-fit and / or form-fit connection.The wall section, which is detachably fixed to the floor wall and / or wall sections of the vehicle, can, for example, at least partially cover a recess in the floor wall. A retaining element can be attached or be attached to the bottom of the container, with which a vehicle wheel or spare wheel, inserted at least partially into the container, can be fixed directly or by means of a connecting element, either within or to the container. The container can, for example, have at least one forward-projecting tab on its bottom which, when the container is detachably fixed to the floor wall, engages a supporting wall section on the floor wall of the vehicle.For example, at least one tab can form a U-shaped section in cross-section with a free, forward-projecting tab leg. When the container is detachably fixed to the vehicle floor, this tab leg engages a flange on the vehicle floor wall that extends rearward between the legs of the U-shaped section. For example, the flange can also project rearward at the front upper edge of the recess. Displacement of the container installed in the vehicle, in each longitudinal direction, can be prevented, for example, forward by a front support wall section of the vehicle body and / or by at least one front intermediate section located immediately behind it, and rearward by at least one intermediate section located between the container and a rear support wall section of the vehicle body and / or a rear intermediate section located immediately in front of it.Of course, other configurations are also possible. For example, the front intermediate section can have two corner areas arranged on the floor wall, connected in the transverse direction of the vehicle. Additionally, the corner areas of the front intermediate section can each have a convexly curved vertical wall section, segment-shaped relative to a real or virtual perpendicular axis, forming a circular cylinder segment. At least one rear intermediate section can be provided, which, for example, is arranged between the container and a rear support wall and prevents significant backward movement of the container.

[0030] If, for example, two rear intermediate sections are provided, these can be arranged side by side and, for example, detachably connected to each other in the transverse direction of the vehicle by force-fit or form-fit. The at least one rear intermediate section can be designed in a frame-like form with vertical circumferential walls. For example, at least one rear intermediate section can additionally have a convexly curved, circular-cylindrical segment of vertical circumferential wall in certain areas, perpendicular to a real or virtual perpendicular axis. For example, the vertical circumferential walls of at least one rear intermediate section can be connected via a base section and, for example, form at least one open-topped receiving compartment with the base section.The convexly curved, circular-cylindrical segment-shaped vertical wall sections of the front intermediate parts, and optionally the convexly curved, circular-cylindrical segment-shaped vertical circumferential wall sections of the rear intermediate parts, can each be convexly curved about a common real or virtual vertical axis. For example, if a vehicle wheel or spare wheel is placed in the container, a small parts container, open at least on one side (e.g., top or bottom), can be recessed in the wheel well and secured by friction and / or form-fitting. The small parts container, manufactured, for example, from an injection-molded plastic part, can have a central through-opening through which the small parts container is attached to the vehicle wheel or spare wheel and / or to the container in the well using the retaining element or, additionally, a fastening element connectable to the retaining element.In this embodiment, the additional fastening element is a rotary handle connected to a threaded rod in a rotationally fixed manner. The threaded rod can be screwed into a threaded nut in the retaining element, which is fixedly or releasably attached to the bottom of the container. Other materials can also be used for the components. In this embodiment, the container is made of ABS-PC plastic or, alternatively, of a deep-drawn trilaminate, and the small parts container is made of an epoxy resin. The rear intermediate parts used in this embodiment are, for example, made of an epoxy resin and laminated with a luggage compartment cover or a non-woven velour made of PP / PPS. In this embodiment, the small parts container accommodates at least one jack inside.
