Composite performance construction of an aircraft cockpit stiffened by the spatial framework

The object of the invention is a composite durable structure of an airplane cabin, stiffened by a spatial frame, for the crew and passengers, in particular an airplane cabin segment (1) for crew and passengers positioned substantially in a central part of the airplane fuselage, in particular of a small airplane.The composite durable structure, stiffened by a spatial frame, in which a passenger bench is positioned, is characterized in that the composite durable structure of the airplane, stiffened by the spatial frame, is constituted by a spatial frame (2) formed by mutually coupled elements of the passenger bench: a backrest framing (3), a seat framing (4), an armrest framing (5), and complementary elements (6).
