Technical Services Participant Bulletin
DATE: November 16, 2004 FROM: National Staff TO: All Participants
SUBJECT: Airbag Advisory
It has been brought to the attention of SCCA Technical Services that the use of full-face or closed-face helmets while driving vehicles with active airbag restraint systems may result in injuries in the event of a crash that deploys the airbag. Because of the location of the steering wheel relative to a driverís position, the airbag axis is on a level with the driverís chin. 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 vehicle 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. Potentially more restrictive language is currently being considered for 2005, which could appear in an early 2005 issue of FasTrack. If you have any questions, please contact the SCCA at (800) 770-2055.
