1. Device for the directional support and adjustment of various members, with respect to a reference plane (6), characterized in that it comprises : - an envelope (1) in elastically non-deformable supple material, defining a tight chamber (2), - a connection piece (13) adapted on the envelope in order to isolate it from or connect it with the environment or to connect said chamber with a circuit for creating a relative vacuum, - a mass (3) of resilient elements occupying part of the maximum volume of the chamber when the latter is connected with the environment, - at least two plates (4) and (5) fast with the envelope and designed to act, respectively, as a removable fixing stand with respect to a reference plane (6) and as a directional support and adjustment element for a member of any type (0), - and anchoring means (10 and 12) fast with the plates, having no positive link one with the other and being directed towards the volume of the chamber in such a way as to sink at least partly in the mass of resilient elements. |
