The extensible meshed bi-structure comprises: • a first meshed structure (SM1), the meshes being distributed along a first plane, the first meshed structure (SM1) being foldable along a first direction (D1) comprises in the first plane (P1); • a frame structure (SC) comprising at least two longitudinal elements rigidly connected to the first meshed structure (SM1) and arranged on either side of the opposing edges of said first meshed structure (SM1) and making it possible to vary the dimensions of the bi-structure; • a second meshed structure (SM2), the meshes being distributed along a second plane (P2) parallel to the first plane, the second meshed structure (SM2) being foldable along the first direction (D1); • connection means (ML) between the first meshed structure (SM1) and the second meshed structure (SM2) so as to rigidly connect the two meshed structures to one another, the connecting means enabling synchronization of the folding of the two meshed structures (SM1, SM2) in the first direction (D1). The second meshed structure (SM2) comprising a number (N2) of meshes strictly greater than the number (N1) of meshes of the first meshed structure (SM1), the ratio (RPN) between the number of meshes (N2) of the second meshed structure (S2) and the number of meshes (N1) of the first meshed structure (SM1) being substantially close to the ratio (RPL) between the width of a layer (L1) of the first meshed structure (S1) and the width of a layer (L2) of the second meshed structure (S2). |
