A gas spring device (20) arranged between the covering and the frames has an end flexibly mounted at a pivot point (26) in the covering and another end flexibly mounted on a roller lever (28). The device is hinged between the axis and the point. A roller (30) rotatably mounted on the point runs on a turning web (32) of a turning device (34) attached to the frames, where web is formed in such a manner that covering is provided in all rotating positions in equilibration.</p> |
