Abstract

La présente invention concerne un dispositif à géométrie variable de type bistable comprenant une paire d’éléments liés entre eux en une première zone formant une première articulation, une seconde zone de chaque élément de cette paire d’éléments étant liée à un support par une seconde articulation, la première articulation étant apte à occuper deux états stables respectivement situés de part et d’autre d’une ligne joignant les deux secondes articulations. Ce dispositif est caractérisé en ce qu’au moins l’un des deux dits éléments et/ou au moins l’un des deux supports est réalisé en un matériau apte à se déformer élastiquement, de façon à permettre le passage de la première articulation de part et d’autre de ladite ligne.
