ABSTRACT:
The invention refers to a device (3) for actuating a membrane arranged in an opening to a space, and a vehicle having such a device. The membrane (1) has a first surface (1′) and a second opposite surface (1″), and is limited by an edge area. The device includes a first strip (5) to be attached to the first surface of the membrane in the edge area, and a second strip (6) to be attached to a surface of a frame portion extending around the opening. An exchanging number (8) is arranged between and connecting the first strip with the second strip. An actuating member (20) 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.
