Fig. 8.5. Vehicle cabin: 1 – roof reinforcement; 2 – central pillar; 3 – lateral longitudinal beam; 4 – cross member No.2; 5 – cross member No.3; 6 – front door impact-resistant beam; 7 – rear door impact bar; 8 – collision energy
The floor, side frame and roof form three rigid, H-shaped frames (triple H-shaped construction), which resist the impact force in the event of a side collision (Fig. 8.5). Handling stability is improved by preventing body twisting.
