Abstract:
1. A device comprising: at least one flexible portion between two stiff portions, which are stiffer than said at least one flexible portion, each of said two stiff portions being made of stiff composite material, said at least one flexible portion connecting said two stiff portions and forming a flexible hinge between said two stiff portions, each of said two stiff portions comprising, said at least one flexible portion being formed by at least one flexible material selected from the group of flexible composite materials comprising, wherein, said two stiff portions have end surfaces that oppose each other when said device is in an extended state, where the stiff portions and said at least one flexible portion are in a longitudinal extension of one another, said at least one flexible portion axially compressing under longitudinal compression forces in the extended state, said end surfaces of said stiff portions being arranged in the extended state to come into flat surface contact with each other and at a neutral longitudinal axis of the device after axial compression deformation of said at least one flexible portion so that said end surfaces act as abutments transmitting the longitudinal compression forces at least along said neutral longitudinal axis and torsion forces, and said end surfaces being arranged to enable the flexible hinge thus formed to fold back, at least in a direction away from the extended state.
