PROTECTION OF OCCUPANTS OF COMMERCIAL VEHICLES BY INTEGRATED SEAT/BELT SYSTEMS

Five different types of integrated seat/belt systems were evaluated in frontal crash experiments at an impact speed of 35 km/h, using dummies in a truck cab on the catapult unit. The results were compared with those obtained with conventional three-point belts and with unrestrained dummies. The experimental results showed that when the dummy was unrestrained or protected only by a lap belt, the upper load limits used as protection criteria were far exceeded because of the heavy impact on the steering wheel; this did not apply to three-point belt systems. Very favorable forward displacement kinematics were achieved when using special seats of adequate structural strength with integrated three-point belt systems. The experiment showed that a vibration-absorbing seat with integrated three-point belt and additional supports fitted to the seat and backrest is the optimum solution.
