Safety Restraint Systems in Heavy Truck Rollover Scenarios

Safety restraint systems have been widely applied in the passenger car industry. The heavy truck industry has followed along, integrating the seat belts in the seat system. The effectiveness of seat belts, in particular in rollover scenarios, was studied for a number of heavy truck rollover scenarios. Driver and passenger in the front seats have been modeled, and a side-facing occupant in the back has also been included in the model. Unbelted versus belted occupants are evaluated, and from the calculated injuries for the occupants, some recommendations for restraint systems are provided.
