A device for relative movement of two elements (1, 2) comprises at least two first links (8, 9), which are connected relative to a first (1) of the elements via hinges (10, 11) and which are pivotable in substantially parallel panes relative to the first element (1) under influence of at least one first power-exerting member (12). At least two second links (14, 15), which are connected relative to a second (2) of the elements via hinges (16, 17), are pivotable in substantially parallel planes relative to the second element under influence of at least one second power-exerting member (18). The two first links (8, 9) form a first four-hinges system (FS1). The two second links (14, 15) form a second four-hinges system (FS2). These two four-hinges systems are coupled in series to each other between the first and second elements (1, 2). |
