In order to increase protection for older occupants, the Frontal Impact informal group proposes to decrease the permissible chest deflection for the 50th percentile Hybrid III dummy to 42 mm from the current 50 mm. (This change is proposed in concert with the development of a new frontal impact regulation focused on occupant restraint systems.)
23. The expert from France, Chair of the IWG on frontal impact, introduced the status report of the group (GRSP-54-40). He informed GRSP that the IWG was ready to submit a proposal for the May 2014 session of GRSP and introduced a first draft for information only (GRSP-54-27). He clarified that the amendment would introduce: (i) a full-width frontal crash test against a rigid barrier at 50 km/h, (ii) a new biomechanical criteria for elderly people (65 years and older) and (iii) the 5th percentile female dummy. The expert from Japan made a presentation (GRSP-54-25) to show the influence of the diagonal safety-belt path to chest deflection and announced a proposal to address this issue in the framework of activities of the IWG. The expert from France confirmed the importance of the belt position for the thorax deflection and clarified that the current proposal of the IWG addressed both sexes, as well as covering the safety of younger occupants. Finally, GRSP unanimously agreed to resume consideration on this agenda item at its May 2014 session on the basis of a concrete proposal for a new UN Regulation instead of an amendment to UN Regulation No. 94, drafted by the IWG.
