    • 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.
    • 用于两个元件(1,2)的相对运动的装置包括通过连接装置(4)串联耦合的两个连杆装置(5,6)。 第一连杆装置(5)包括至少三个连杆(9,14),它们的长度基本相等且平行,所述连杆沿着连杆的纵向方向以连接装置(4 )和元素(2)。 第二连杆装置(6)包括作用在连接装置(4)和元件(1)之间的至少一个平行四边形。 第一和第二施力装置(17,18)适于使第一连杆装置(5)枢转。 第三施力装置(33)适于使第二连杆装置(6)枢转。
