Device For Actuating A Membrane And A Vehicle Comprising A Device For Actuating A Membrane

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.
