Limitations in the
Current regulations test helmets in a straight line, i.e. perpendicular to the impact surface. Certimoov adds oblique impacts to its tests, which better reflects the real conditions of collision (e.g. impact on a road with a component of horizontal speed).
For European regulations, the criteria for the acceptance of a helmet is based on the translational acceleration registered with a rigid headform which does not faithfully represent the human brain and considers pass/fail criteria which is not particularly representative of the impact tolerance limits of brain. Certimoov works with a more complex mathematical head model and considers brain injury criteria drawn from over hundred real world head trauma. These elements enable bioengineers and Certimoov to base their tests on more realistic injury criteria which corresponds to the actual impact tolerance of the brain.
The regulation’s pass/fail criteria for helmet acceptance is yes or no: either the helmet fulfils the regulation or it does not. Certimoov enables the addition of nuances to the tests with a score from 0 to 5.
A tripartite project
Three entities are behind Certimoov: the MAIF Foundation, which co-financed the development of the test method, the University of Strasbourg, which developed the test method and as of today carries out the tests, and Mutuelle des Motards, which makes the project ongoing by financing test campaigns and notifying helmet users and manufacturers so that they can improve their manufacturing methods.
