Abstract

A motor vehicle 1 comprising a cargo bay 2, which may be a vehicle boot and a first loading platform 3 which can be pulled out of the cargo bay and comprises guide rails (4, 4', Figure 1) which are arranged at the top of said loading platform 3 and are fixed thereto for the purpose of lateral guidance of a second loading platform 5 which is displaceable beyond the first loading platform 3 in the direction of the longitudinal axis of the motor vehicle 2. The two loading platforms 3, 5 can jointly be transferred over a rear edge (6, Figure 3) of themotor vehicle 1 in the direction of the longitudinal axis of the motor vehicle to a first loading position for loading the second loading platform 5 and where a transfer from the first loading position to a second loading position for loading the first loading platform 3 can be achieved such a way that the second loading platform 5 is displaceable on the first loading platform 3 into the cargo bay in order to thus expose a rear region 9 of the first loading platform.

Description

A motor vehicle with a cargo bay. loadable in Iwo loading positions The novelty relates to a motor vehicle with a cargo.bay, which can be loaded in two loading positions.

A trunk floor for a cargo bay of a motor vehicle, especially a passenger car, is known from DE 10241 687 Al1 comprising an extendable loading platform. The loading platform is pulled beyond the rear edge of the motor vehicle from the cargo bay for a first loading position. Loads such as baggage items, beverage crates and the like can be positioned in an ergonomically advanlageous manner directly on the loading platform without damaging the lower back panel, the fender or other elements of the motor vehicle. If several loads in form of heavy baggage items need to be transported in the cargo bay of the motor veticle, it is necessary to displace the loads which were loaded and positioned first on the loading platform and which stand in the rear section of the cargo bay, i.e in the rear of the vehicle, in a forward direction in the direction of the back bench in order to place further loads at the rear on the loading platform. The displacement of the loads in a forward direction is always problematic when the loads are heavj or bulky. Alternatively, the loading item could be lifted over the items loaded first, which may lead to undesirable consequences in regard to the health of the user.

One of the novelties of the object of the invention is providing a motor vehicle whose cargo bay can be loaded in a manner that protects the back of a person especially well and in which loads that have already been loaded into the vehicle do not prevent or block a loading of the cargo bay with further loads, or do so to a lesser extent.

This object is achieved by the features of claim 1 Further advantageous embodiments of the novelty are the subject ratter of the dependent claims. They can be combined with each other in a technclogically useful way. The description 3E additionally characterizes and specifies the rovelty, especially in connection with the drawings.

Accordingly, a first embodiment proposes a motor vehicle with a cargo bay and a first loading platform which can be pulled oul of the cargo bay and comprises guide rails arranged on said loading platform and fixed thereto for the lateral guidance of a second loading platform which is displaceable beyond the first loading platform.

In comparison with a loading platform that can be pulled out of the cargo bay and is provided in form of a extendable trunk floor, loading can now simply be shifted to the front in the direction of the rear seats of the motor vehicle. It is therefore possible to load not only the rear section of the cargo bay in an ergonomically advantageous manner. In comparison with known loading platform attachments, the loading items also need not be lifted over the fender into the motor vehicle. As a result of the illustrated effective combination, the novelty provides two advantages over known loading platform arrangements with merely one loading platform.

The guidance of the second loading platform on the first loading platform can principally follow an arrangement according to DE 10 2012 0123 59.0, to which reference is made hereby, in particular to its Fig. 1 and the relevant description of the drawing. It is provided in Fig. 1 shown there that the guide rails are connected in a fixed manner to the cargo bay. The novelty on the other hand provides the fixing of the guide rails, preferably in form of U-sections, to the sides of the first loading platform.

It is provided in an advantageous arrangement of the aforementioned embodiment that the two loading platforms can be transferred together beyond a rear edge of the motor vehicle in the direction of the longitudinal axis of the motor vehicle to a first loading position for loading the second loading platform, and wherein a transfer from the first loading position to a second loading position for loading the first loading platform can be achieved in such a way that the second loading platform is displaceable on the first loading platform into the cargo bay in order to thus expose a rear section of the first loading platform.

Furthermore, the first loading platform has a larger length in the direction of the longitudinal axis of the motor vehicle than the second loading platfomi. In particular, the first loading platform can cover the floor of the cargo bay completely or nearly completely if it has been fully pushed to the front. The length of the first loading platform is advantageously larger by a factor in the range of 1.5 to 3, preferably by a factor in the range of 1.8 to 2.2, more preferably by the factor 2, than the length of the second loading platform in order to keep the loading area of the first bottom loading platform in the aforementioned second loading position sufficiently large, and to simultaneously provide sufficient space on the second upper loading platform.

In a further embodiment, the first loading platform is laterally bounded by two running rails which are fixed to the loading platform and which are respectively guided along a guide rail to the vehicle, which extend parallel to the longitudinal axis of the motor vehicle.

Alternatively, the first loading platform can also be pulled out of the cargo bay by means of known guide and pivoting elements which are also arranged on the side, and can simultaneously be lifted over the rear loading edge of the motor vehicle. In this respect, the first loading platform can also be regarded as the trunk floor.

A number of embodiments will be explained below in closer detail by reference to the drawings, wherein: Fig. 1 shows a motor vehicle in a first loading position; Fig. 2 shows the motor vehicle according to Fig. 2 in a second loading position; Fig. 3 shows the motor vehicle according to Fig. 2 with a loaded trunk.

Fig. 1 shows a cargo bay 2 of a motor vehicle 1. The cargo bay 2 extendsin this case from a rear seating arrangement 12 of the motor vehicle 1 to a rear trunk sill 17, which is formed by the fender of the motor vehicle 2. A rear edge 6 of the motor vehicle is further shown.

A bottom first loading platform 3 is arranged in the cargo bay 2, which first loading platform 3, in the position shown in Fig. 3, covers the available trunk floor of the cargo bay 2. Two guide rails 4, 4' are arranged at the top laterally on the loading platform 3. Said guide rails 4, 4' are used for laterally guided accommodation of a second loading platform 5 which is displaceable therein and respectively extend over 33 the entire length 11 of the first loading platform 3. The second loading platform 5 is displaced in the illustrated first loading position 7 from the rear seating arrangement 12 of the motor vehicle ito the rear beyond the edge 6. The second upper loading platform 5 covers the first bottom loading platform 3 only in part. A front region of the first loading platform 3 is exposed, wherein this region corresponds approximately to half the total loading area of the first loading platform. The illustration further shows handles, which are arranged in a respectively central manner on the loading platforms. The first loading platform is therefore shown in a position where it is pulled out of the cargo bay beyond a rear edge of the motor vehicle. The second upper loading platform is thus also shown in the pulled-out position. This corresponds to the first loading position 7. Two cargo elements 13, 14 are shown by way of example, which in this first loading position 7 are placed on the second loading platform 5.

Fig. 2 shows the cargo bay in a second loading position 8. The second loading platform 5 is displaced forwardly in this loading position 8 and releases a rear region 9 of the first loading platform 3 for loading. Two further cargo elements 15, 16 are shown by way of example, which in this second loading position 8 are placed on the first bottom loading platform 5.

In Fig. 3, both loading platforms are finally pushed to the front in the longitudinal direction of the motor vehicle. The cargo bay 2 can be closed in this position prior to transport.

Components that have the same function or act functionally in the same way are provided with the same reference numerals in the drawings.
