A structural supporting truss (12) comprises an elongate rib (14) of resilient material connected to a web (16) of fabric material. The rib (14), in use, is elastically deformed to adopt a curved shape. The web (16) extends radially inwardly of the rib (14) along its length, the web (16) acting in tension to retain the rib (14) in its curved condition. The rib (14) may be made of a plurality of segments interconnected by hinges. The web (16) may comprise a plurality of panels (20). The rib (14) is subject to a compressive force. A remarkably stiff truss structure is formed such as may be used as a supporting truss for a tent of like shelter structure.

La présente invention concerne une armature (12) porteuse structurale, qui comprend une nervure allongée (14) faite d'un matériau élastique et reliée à une toile (16) en matériau textile. Pendant l'utilisation, la nervure (14) se déforme élastiquement pour prendre une forme courbe. La toile (16) s'étend radialement vers l'intérieur de la nervure (14), sur sa longueur, et elle travaille en tension pour maintenir la nervure (14) dans sa forme courbe. La nervure (14) peut être constituée par plusieurs segments reliés par des charnières. La toile (16) peut comprendre plusieurs panneaux (20). La nervure (14) subit une force de compression. On obtient ainsi une structure à armature remarquablement rigide, qui peut être utilisée comme support pour une tente d'une structure analogue à celle d'un abri.
