FI | Session 18 | 30 Jan 2013

X.Trosseille informs the group that a first webex meeting was held in W48/12. An evaluation matrix has been developed to assess the pros and cons of different thorax injury criteria/measures.

Feedback was requested by experts, but only NHTSA (Steven Ridella) has given feedback by now. Further feedback is expected from OICA, Germany and Japan. Another webex will be scheduled for mid/end of February 2013.

Mr. Ammerlaan remarked that a reasonable balancing between local belt loading and distributed airbag loading is necessary. Focusing too much on the frontal impact situation the group has to consider, that the belt has the duty to keep the occupants in place (e.g. in over role accidents) and therefore a certain minimum belt load should be considered.

Mr. Faure remarked that a similar argument was already raised from Thomas Herpich (TRW) during the NCAP frontal impact group meetings and that it will be considered.

Mrs. Sunnevang gave a presentation on simulations made by Autoliv to evaluate the DEQ criteria for a variation of load limiter and airbag systems and crash pulses.
