Juste pour montrer la complexité du débat :
From the SCCA Technical Services:
"In a crash with airbag deployment, contact with the chin area of a full face helmet can be so powerful "that the risk of fractures to the jaw cannot be ruled out" (Hubert Gramling, FIA Institute, FT3?AF, 18.5.1999). This applies to vehicles that may be used in Solo, RallyCross, High Performance Car Control Clinics, etc.
Therefore, it is highly recommended that full-face helmets not be used in vehicles with functional airbag systems. If you have any questions, please contact the SCCA at 800.770.2055."
J'ai longtemps eu un open face et c'est utile quand tu coach sans micro...maintenant full face visière fermée pour prévenir les débris.
