The invention relates to a vehicle according to the preamble of claim 1.

The problem with cars is that when they are parked parallel to one another in a parking lot, there is a very real risk that if you open the door carelessly, the side of the car next to you will be damaged and the door of your own vehicle will also be damaged, particularly at the edges. For this reason, it is common practice to provide the side areas of the doors with longitudinal plastic or rubber strips.

These protective strips generally serve their purpose for the front doors, but they are often unsuitable for protective purposes on the rear doors of a vehicle. This is particularly due to the fact that the rear door of a vehicle has a recess in the area of the rear wheel, so that the upper part of the door extends backwards. Since there is usually no protective strip here, the risk of damage is very high.

Another problem is the trunk lids of motor vehicles and, in particular, the rear doors of caravans, which can easily be hit when opening and, as a result, can potentially cause injury.

Based on this, the object of the invention is to create an improved buffer as protection against damage when opening the door.

Postbank Karlsruhe (SLZ !66010075} Account No. 438 69-752

The technical solution is characterized by the features in the characterizing part of claim 1.

The basic idea of the buffer device according to the invention is that it is no longer designed as a strip fixed to the door as before, but that the buffer is a movable part. In the non-use position, i.e. when the door is closed, the buffer is in a retracted position in which it is not visually disturbing. Only when the door is opened is the buffer moved into the use position so that it can develop its protective effect. As a rule, the buffer, which can be made of rubber or plastic, will be a body which is attached where the door has protruding areas. For the front door, this will be the generally straight, vertical rear edge of the free end of the door. For the rear door, the buffer will be located in the upper area near the opening handle. It is of course conceivable that not just one buffer but several buffers can be assigned to a door. When the buffer according to the invention is used, particularly for rear doors of caravans, the risk of injury when opening is reduced.

As already described above, according to the further development in claim 2, the buffer is arranged in the area of the free end of the door. This is to be understood as the area of the door facing away from the rotary hinge.

The basic idea of the further development according to claim 3 is that the movement of the buffer is coupled with the opening and closing movement of the door.

Preferably, according to the development in claim 4, this is a mechanical device. Of course, the device can also be a pneumatic, hydraulic or electrical device.

In principle, it is conceivable that the buffer is moved linearly. The development according to claim 5, however, proposes the arrangement of the buffer on a pivotable lever. This means that when the door is closed, the lever is in the pivoted-back non-use position, but when the door is opened, the lever is automatically pivoted outwards. The lever can be angled so that the buffer, as it were, grips the rear edge of the door outwards.

Preferably, according to claim 6, the lever is hinged to the free front side of the door.

In order to automatically operate the lever when opening and closing the door, a linkage is provided between the lever and the body frame according to the development in claim 7. This linkage can be a rod. The basic idea is that by linking the linkage to the fixed body frame at a distance from the door hinge, the linkage is either shortened or lengthened when the door is pivoted. This difference in length is used by a corresponding linkage on the buffer lever to pivot the lever equally during the pivoting movement of the door. The buffer lever can be a two-armed lever, for example.

The further development according to claim 8 creates a technically simple and, above all, non-disturbing course of the rods.

An embodiment of a buffer according to the invention for vehicles as protection against damage when opening the door is described below with reference to the drawings. In these:

Fig. 1 is a side view of the door of a vehicle with protruding

swiveled buffer;

Fig. 2 a horizontal section through the vehicle door in the closed

sen state;

Fig. 3 shows a section corresponding to Fig. 2 with the door open.

The vehicle has a fixed body frame 1. In abstract terms, this refers to all parts of the vehicle that cannot be opened, such as the doors, the trunk and the hood. In particular, the body frame 1 is the frame surrounding the door.

A door 2 is hinged to this body frame 1 on a hinge 3. The closed position of the door 2 can be seen in Fig. 2 and the open position of the door 2 in Fig. 3.

The outer, free end of the door 2 facing away from the hinge 3 has a front side 4. A two-armed lever 5 is hinged to this front side 4, with one arm being bent

and has a cylindrical buffer 6 at its front end. A linkage 7 in the form of a rod is hinged to the second arm of the lever 5. The other end of the linkage 7 is hinged to the body frame 1.

It works as follows:

In the closed position of the door 2, as shown in Fig. 2, the lever 5 is pivoted back such that the buffer 6 lies in the space between the front side 4 of the door 2 and the adjacent body frame 1. When the door is opened, the lever 5 is forcibly pivoted by means of the rod 7 such that the buffer 6 is moved outwards so that the buffer 6 protrudes over the front of the door 2 and comes to lie in the front edge area of the front side 4 of the door 2. If this area of the door 2 is pushed against the side of an adjacent car, the buffer 6 is in between and prevents damage. When the door 2 is closed, the lever 5 is pivoted back from the open position shown in Fig. 3 into the non-use position in Fig. 2.
