Effectiveness of a Vehicle Restraint System Considering Different Anthropometric Human Standards 2010-36-0220

The proposal of this paper is to analyze the occupant protection level of a vehicle restraint system in a frontal crash, considering different anthropometric human standards. The CONTRAN 221/07 Resolution of frontal impact determines the biomechanics criteria for 50th percentile dummies, which comprises the average of the population. This paper aims a wider spectrum, investigating anthropometric human standards other than the average.
Through experimental tests and numerical simulations, where the biomechanics ratios from the 5th, 50th and 95th percentile dummies submitted to the same level of deceleration are compared, this paper identifies potential critical points for the human standards other than the average to reach the biomechanics limits, and based on the results, fosters the discussion of what could be the alternatives to mitigate a possible mismatch in terms of protection to the occupants of average and extreme biotypes.
