The driving device is common to the linkage mechanisms and is together with the parts of the linkage mechanisms engaging it mounted in a common housing (7) for receiving the entire length of the linkage mechanisms (3,4) and provided with guides (8,9) and lead-in openings (8a,9a) for the linkage mechanisms (3,4). A carrier element (10,11) in connection with the guides is via transmission elements (12-16) in the housing 87,28; 54) connected with a common driving unit (17).
