Research has shown that dynamic testing under Appendix 1 is more demanding than the static testing under Appendix 5. As a result, approvals based upon static testing are not equivalent to approvals based on dynamic testing. This proposal, therefore, would delete Appendix 5. In addition, this proposal amends Appendix 1 by reducing the forward movement of the head of the manikin to 1.2 m in alignment with UN Regulation No. 14. Further, the proposal would limit the movement of the seat anchorages to 100 mm to ensure a minimum residual space for the passenger between the seats. Lastly, to ensure that seat fixations are reliably fastened after relocation, the proposal would require the necessary information to be marked directly on the seat and provided in the owner’s manual.
51. The expert from Germany gave two presentations (GRSP-62-35 and GRSP-62-36) to introduce a proposal of amendment (GRSP-62-12) to the UN Regulation aimed at removing the static tests and improving the dynamic test on seat anchorages. Referring also to the video presentations Nos. 1 and 2, he provided evidence that seat anchorages tested statically do not reach the same level of safety as that tested dynamically and, therefore, they cannot be considered as equivalent. GRSP agreed to resume discussion on this subject at its May 2018 session and requested the secretariat to distribute GRSP-62-12 with an official symbol.
