This paper corresponds to the research theme developed in my Doctoral thesis. It starts with the Architect Emilio Pérez Piñero's work: information is prepared which allows his work to be transmitted and it generalizes the behaviour study related to unfoldable structures. This is a type of structure which requires definition as well as mobility and structural behavior. The unfoldable structures studied are characterized by using bars placed in the shape of an "X" in the structure's thickness in both flat and curved surfaces. In both cases, mobility in the mechanism stage is analyzed using Piñero's Solutions and complementary solutions mentioned. The geometric relations which must be fufilled so that the bar movement is possible and which determine its constructive definition are studied. Several types of structures which are possible starting from flat deployable mechanisms are mentioned and this procedure can be extrapolated for curved surfaces.
