Motor vehicle body with plasma-treated gluing surface

1. A motor vehicle body, comprising:

at least one marginal portion delimiting a bodywork opening, the bodywork opening having a first plasma-treated gluing surface and a second plasma-treated gluing surface;

a first seal fastened in a materially-joined manner to the first plasma-treated gluing surface, the seal comprising a first fastening portion, which is fastened to the first plasma-treated gluing surface by means of a first double-sided adhesive tape; and

a second seal fastened in a materially joined manner to the second plasma-treated gluing surface, the seal comprising a second fastening portion, which is fastened to the second plasma-treated gluing surface by means of a second double-sided adhesive tape;

wherein the first fastening portion comprises two legs oriented at a predetermined angle to each other, wherein one leg is fastened by means of the first double-sided adhesive tape to the first plasma-treated gluing surface of the motor-vehicle body formed on a flange and the other leg extends over and beyond a face end of the flange;

wherein the second fastening portion comprises a U-profile, further comprising two parallel legs which form a groove-like mounting between them, wherein an outside of one of the two parallel legs is fastened to the second plasma-treated gluing surface using the second double-sided adhesive tape, and wherein the groove-like mounting is oriented in parallel to the second plasma-treated gluing surface; and

wherein a sealing portion directly adjoins a leg of the first fastening portion of the seal provided with the first double-sided adhesive tape.

2. The motor vehicle body according to claim 1 , wherein the first fastening portion comprises at least one extension extending over and beyond the first plasma-treated gluing surface, which at least in certain areas covers a covering component.

3. The motor vehicle body according to claim 1 , wherein the first plasma-treated gluing surface and the second plasma-treated gluing surface are cleaned by means of an atmospheric plasma.

4. A motor vehicle comprising:

a body having at least one opening, the opening having a first plasma-treated gluing surface and a second plasma-treated gluing surface;

a first seal having a first fastening portion, which is fastened to the first plasma-treated gluing surface by means of a first double-sided adhesive tape; and

a second seal comprising a second fastening portion, which is fastened to the second plasma-treated gluing surface by means of a second double-sided adhesive tape;

wherein the first fastening portion comprises two legs oriented at a predetermined angle to each other, wherein one leg is fastened by means of the first double-sided adhesive tape to the first plasma-treated gluing surface of the body formed on a flange and the other leg extends over and beyond a face end of the flange;

wherein the second fastening portion comprises a U-profile, further comprising two parallel legs which form a groove-like mounting between them, wherein an outside of one of the two parallel legs is fastened to the second plasma-treated gluing surface using the second double-sided adhesive tape, and wherein the groove-like mounting is oriented in parallel to the second plasma-treated gluing surface; and

wherein a sealing portion directly adjoins a leg of the first fastening portion of the seal provided with the first double-sided adhesive tape.

5. The motor vehicle according to claim 4 , wherein the fastening portion comprises at least one extension extending over and beyond the first plasma-treated gluing surface, which at least in certain areas covers a covering component.

6. The motor vehicle according to claim 4 , wherein the first plasma-treated gluing surface and the second plasma-treated gluing surface are cleaned by means of an atmospheric plasma.
