A device for relative movement of two elements (1, 2) comprises two link arrangements (5, 6) coupled in series by means of a connection arrangement (4). A first link arrangement (5) comprises at least three links (9, 14) which are substantially equal in length and parallel, said links being positioned in a substantially triangular relation viewed along the longitudinal direction of the links, between the connection arrangement (4) and the element (2). The second link arrangement (6) comprises at least one parallelogram acting between the connection arrangement (4) and the element (1). First and second force applying arrangements (17, 18) are adapted to cause the first link arrangement (5) to pivot. A third force applying arrangement (33) is adapted to cause the second link arrangement (6) to pivot.
L'invention se rapporte à un dispositif pour le mouvement relatif de deux éléments (1, 2), qui comprend deux assemblages de liaison (5, 6) couplés en série par un agencement de connexion (4). Un premier assemblage de liaison (5) comprend au moins trois liaisons (9, 14) qui sont sensiblement parallèles et égales en longueur, lesdites liaisons étant placées en relation sensiblement triangulaire selon leur direction longitudinale, entre l'agencement de connexion (4) et l'élément (2). Le second assemblage de liaison (6) comprend au moins un parallélogramme agissant entre l'agencement de connexion (4) et l'élément (1). Un premier et un second assemblage (17, 18) sont conçus pour appliquer une force et faire pivoter le premier assemblage de liaison (5). Un troisième assemblage (33) est conçu pour appliquer une force et faire pivoter le second assemblage de liaison (6).
