Description

The present invention relates to a carrier for mounting on a motor vehicle, in particular a carrier for accommodating a trailer coupling head, for accommodating bicycles or another load to be carried outside the interior of the motor vehicle.

Trailer couplings, whether fixed, swing-out or attachable, are among the components of a motor vehicle which, if necessary, enormously increase the vehicle's potential for use. For example, it is possible to transport bicycles on the trailer hitch, to attach an additional transport box to the trailer hitch, to mount ski or game carriers or to attach a trailer.

In modern motor vehicles, in particular in electric vehicles, however, trailer couplings are found less and less as optional equipment that can be additionally configured. The main reason for this is that the effective range of the motor vehicle decreases significantly when the trailer hitch is used. In addition, the bracket for the trailer hitch, which is typically located below the rear apron and consists of a cross member welded to the body, is quite heavy, which also reduces the range.

It is therefore an object of the present invention to provide a carrier for mounting on a motor vehicle which does not have the disadvantages of the prior art mentioned but can take loads outside the motor vehicle like a trailer hitch of the motor vehicle, is correspondingly stable and simple can be assembled and disassembled.

This object is achieved by a carrier for mounting on a motor vehicle, the carrier having a first retaining arm and a second retaining arm arranged parallel to the first retaining arm for attachment to retaining points of the motor vehicle and a cross member connecting the retaining arms and arranged orthogonally to the retaining arms, the carrier a first stiffening arm and a second stiffening arm for connecting the support arms and the cross member.

The carrier according to the invention enables simple assembly at two breakpoints of the motor vehicle. As a result, a cross member arranged permanently on the motor vehicle is not possible. Instead, the carrier is assembled or disassembled depending on use. The cross member of the beam allows loads to be placed on it. This can be, for example, bicycles, skis, a luggage box, a game tub, a coupling head of a trailer hitch, a pin coupling, a jaw coupling or a fifth wheel coupling.

The stiffening arms cleverly direct the forces that occur here from the cross member via the retaining arms to the retaining points, which gives the carrier significantly increased stability.

Connected within the meaning of the present invention means directly connected to one another. It is conceivable that connected parts are welded together. However, it is also conceivable that connected parts are screwed or riveted to one another.

It is conceivable that the carrier has a lighting system which can be connected to the motor vehicle via a trailer socket.
