Fig. 8.5. Car cabin: 1–amplifier of a roof; 2–central rack; 3–lateral 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
The floor, lateral frame and roof form three rigid, N-shaped (((((a threefold H-shaped design) which resist to force of blow in case of lateral collision (fig. 8.5). Stability of management improves prevention of torsion of a body.
