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.
