Abstract: The invention concerns a device for producing movements of a cabin (or of a platform) along 3, 4 or 6 axes, enabling a dynamic simulator to obtained, easy to produce, light and with little vertical space requirement. It consists of a structure (7) designed to receive a cabin whereof the movement is controlled by a set of six passive or active arms acting in traction/compression connected to the frame (1), the number of active arms being equal to the number of axes of displacements. The drawing represents a version with 4 axes and 4 active arms (12) (13) (14) (64) and 2 passive arms (61) (62). The displacement can be shifted from 4 to 6 axes by activating the arms (61) and (62) and from 4 to 3 axes by rendering passive the arm (64). In certain embodiments, the active arms are mechanized by connecting rods actuated by rotary motors or actuators.
