3. The secretariat of GRSP introduced a presentation (GRSP-70-02) on the work progress of IWG on Safer Transport of Children in Buses and Coaches (IWG-STCBC) to GRSG. The expert from Germany added a clarification that the aim of IWG was a new UN Regulation concerning existing systems used in passenger cars and that the specific new Child Restraint System (CRS) would be not developed. He added that IWG favoured built-in CRS and booster cushions due to their lack of bulk. However, especially in the latter case, the problem of head containment would remain. He also stated that the belt length would be an issue since buses had not been structured to incorporate large rolls of belts to secure CRS. He finally announced that a proposal would be officially presented by IWG at the December 2022 session of GRSP.

31. The expert from Spain, on behalf of IWG on safer transport of children in buses and coaches informed GRSP on the progress (GRSP-70-02). She confirmed that the group was examining different configurations of testing and Child Restraint Systems (CRS) fittings in M3 (e.g. seating position, Q dummies with or without CRS, types of CRS) considering bus requirements. She also confirmed that built-in CRS had been considered but their use as a solution could conflict with structural modification of buses. GRSP agreed to resume consideration on this subject at its May 2022 session.
