Proposal to introduce provisions for the specifications and calibration procedure of the 3-D “H”-point machine and the procedure for determining the “H”-point and the actual torso angle for seating positions in motor vehicles, to be used in all referenced UN Regulations and GTRs.
49. The expert from the Netherlands introduced GRSG-127-37, to propose a new addendum to M.R.1 that reproduces specifications of the 3-D H-point machine. He explained that the same proposal had been discussed at the December 2023 session of GRSP. However, at that session, GRSP agreed to defer the adoption of this proposal to its May 2024 session to also allow adoption at the same time of amendments to relevant UN Regulations and UN GTRs together with those in the remit of GRSG. GRSG endorsed in principle the proposal.
