Description

The invention relates to a loading space enlarging device for a motor vehicle, in particular for a passenger car, in order to enable an enlargement of the available loading space of the motor vehicle.

Motor vehicles typically have a cargo space or a trunk in their rear area. Often the size, but especially the length of this cargo space is too small for the load to be carried. In this case, the load must either be transported on the roof of the car or protrude during transport from a window or the tailgate of the motor vehicle. For example, it may be provided not to close the tailgate or boot lid of the motor vehicle or only partially in order to carry elongated objects, so that the elongated object or objects protrude from the rear of the motor vehicle.

However, both solutions are not optimal, especially in bad weather, since the load and / or the occupants of the motor vehicle are exposed to the weather. Furthermore, an only partially closed rear or boot lid has the disadvantage that exhaust gases, moisture, but especially according to the season particularly cold or warm outside air can reach almost completely uncontrolled in the interior of the vehicle.

The publication DE 10 2009 030 590 A1 discloses a load compartment enlargement device for a motor vehicle, which comprises a stable floor panel, a cloth cover and a tailgate. The base plate is stowed below the loading floor and can be pulled out manually. The fabric cover covers sidewalls of the cargo space enlarger and may consist of several parts. Furthermore, the cargo space enlarging device can be secured to the body of the motor vehicle with fastening means.

The object of the present invention is to provide a loading space enlarging device which is easy to assemble and by means of which even heavy loads can be stably transported.

This object is achieved by the subject matter of the independent claims. Further advantageous developments are the subject of the dependent claims.

According to one embodiment of the invention, a loading space enlarging device of a motor vehicle, in particular a passenger car, is specified, which comprises a stable bottom plate, a stable lower rear section and a tailgate. In a parking position, the bottom plate is arranged in the interior of the motor vehicle. This bottom plate can also be brought into a loading space enlargement position, in which this protrudes from the interior of the motor vehicle. The sturdy lower rear section is stowable on an upper side or on an underside of the stable base plate. In the cargo hold increasing position, the stable lower rear portion abuts against the floor panel, with the tailgate folded up and abutting the stable lower rear portion, so that the tailgate and the stable lower rear portion together form a stable rear. In this case, at least one connecting strut is provided in order to secure the stable base plate in the loading space enlargement position on the vehicle body.

With such a loading space enlarging device, both the charge is advantageously kept within the enlarged cargo space and the stability of the cargo space enlarging device is increased. Thus, by the provided connecting struts, additional stability improvements, since deflections in the vertical main load direction of the cargo space enlarger, ie towards the road surface, can be reduced and in this way the stability of the cargo space enlarger can be exponentially enhanced, which this also for makes heavy loads suitable. The stable rear side also has the advantage that when the cargo slides back, which can happen, for example, during a stronger acceleration process, the charge is reliably held within the enlarged cargo space.

Further, the cargo space enlarging device may comprise cloth side covers which are respectively connected to the body of the motor vehicle, the tailgate and the bottom plate and the stable lower rear portion, for example by means of a zipper or adhesive tapes. By the fabric side covers the cargo space enlarger is further closed and protected the cargo and the occupants against the weather and environmental influences and thus kept independent of the weather.

The connecting struts can be connected in the loading space enlargement position with the body and the stable bottom plate via detachable screw. The detachable screw connections ensure that the connecting struts can be mounted simply and easily. For this purpose, for example, a ball joint may be provided with a ball joint at the corresponding ends of the connecting struts, which can be brought into engagement with the body by means of a hexagon threaded bolt, thereby ensuring a simple assembly of the connecting struts and at the same time prevents unwanted loosening of the screw can be. Furthermore, however, other types of detachable screw connections can also be used in the connection of the connecting struts to the body and the stable base plate.

According to one embodiment, the connecting struts are arranged in the parking position below the stable bottom plate. In this way, available storage space underneath the cargo space can be used effectively, which in addition to the visual appearance of the cargo space in the parking position also increases the safety for the occupants. Thus, the storage of the connecting struts underneath the loading floor avoids that the connecting struts loosen while driving and in the event of an abrupt braking operation or an impact as flying parts can pose a danger to the occupants. Furthermore, also provided for mounting the connecting struts Imbuse can be stored in the parking position below the stable base plate.

Further, a pivotable lever can be arranged on the second connecting strut, which is connected in the loading space enlargement position to the stable rear portion. In one exemplary embodiment, the stable rear section can have a quick-locking device into which a catch hook mounted on the pivotable lever engages, as a result of which the stable rear section can additionally be securely fixed in the loading space enlargement position. This additionally avoids the risk that the connection between the stable rear section and the tailgate can be released and the cargo can slip out of the vehicle and thereby endanger other motor vehicles.

Also, a quick-release device may be provided to connect the second connecting strut to the tailgate. Since the cargo space enlargement device is additionally completed via the fabric side covers, a low-cost and easy-to-install quick-release device proves to be sufficient to securely fix the tailgate in the cargo hold-up position.

In one embodiment, a spring element is provided at the corresponding end of the second connecting strut, which engages in a groove of the tailgate. Such tongue and groove geometries are not only easy to install, but at the same time ensure a good seal.

In the loading space enlargement position further additional taillights can be provided, which are connected via a quick release with the body of the vehicle. Vehicle taillights on a motor vehicle are required by law. Like all lighting equipment on the vehicle exterior body of a motor vehicle and vehicle taillights must be permitted and are subject to appropriate regulations. In a motor vehicle with inventive loading space enlarging device, it may happen that the vehicle rear lights of the motor vehicle for other road users are not or only to a limited extent perceptible. In this case, the additional taillights can be used to ensure that the vehicle rear light functions included in the statutory regulations are complied with. A quick release proves to be particularly favorable, as a result, a time-consuming mounting of the additional vehicle rear lights can be avoided. The cables required for connecting the additional vehicle taillights can be guided, for example, over the loading floor or side walls of the loading space of the motor vehicle.

The invention also provides a motor vehicle which comprises a loading space enlarging device described above. This also charges for which the cargo space of the motor vehicle is too small, especially heavy loads stable and weather-independent transport, the Loading space enlarging device is easy to mount on the motor vehicle.

In summary, it should be noted that with the present invention, a loading space enlarging device is indicated for a motor vehicle, which is easy to mount on the motor vehicle and with the help of which even heavy loads can be stably transported. Thus, the preferably acting in the form of a cross connecting struts acting in the vertical main load direction of the loading space magnifying forces, that is, the weight forces of the charges are better absorbed, which deflections load space enlarging device can be reduced and thus this is also suitable for heavy loads.

The connecting struts can be connected, for example, easily and without much time by releasable screw on the tailgate, the body and a stable bottom plate of the cargo space enlarger. In a parking position, the connecting struts are preferably mounted in a storage space below the loading floor, so that from them, in particular in an abrupt braking operation or an impact, no danger to the occupants of the vehicle.
