ABSTRACT:
A device is provided for actuating a membrane arranged in an opening to a space, and a vehicle having such a device. The membrane has a first surface and a second opposite surface, and is limited by an edge area. The device includes a first strip to be attached to the second surface of the membrane in the edge area, and a second strip to be attached to a surface of a frame portion extending around the opening. An exchanging member is arranged between and connecting the first strip and the second strip. An actuating member is arranged to transfer a reciprocating primary movement to the exchanging member converting the primary movement to a reciprocating secondary movement, which has a longer length of stroke than the primary movement and acts on the strips to move towards and away from each other.
