8.1.1.3. Cabin

Fig. 8.3. Car cabin: 1 – amplifier of a roof; 2 – central rack; 3 – side longitudinal beam; 4 – cross-piece No. 2; 5 – cross-piece No. 3; 6 – shock-proof bar of a forward door; 7 – shock-proof bar of a back door; 8 – energy of collision

Floor, side frame and roof form three rigid, N-shaped frames (a threefold H-shaped design) which resist to blow force in case of side crash. Stability of management improves prevention of torsion of a body.
