Proposal to limit the use of a booster cushion (booster seat without backrest) with children of a stature greater than 125 cm (i.e., prohibit use of booster cushion for children under 125 cm) and the application for type approval of such CRS only in mass Group III for children of mass from 22 kg to 36 kg and to clarify that a guide strap which constrains the shoulder strap of the adult seat belt in a position to suit the child in a child restraint system cannot be approved as a separate CRS under UN R44.
27. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2019/28 aimed at clarifying the types of belt-guides and sitting devices that would not be allowed by means of an explanation in the scope of the UN Regulation. The expert from Poland argued that the proposal from EC was restrictive and requested a facts-based discussion on this proposal or a simple rejection in full. He introduced a presentation GRSP-66-19, showing that one of the devices in ECE/TRANS/WP.29/GRSP/2019/28 was fully compliant with UN Regulation No. 44 and safer compared to other type approved CRS. The expert from Spain introduced GRSP-66-30 which provided counter evidence that belt-guide devices would not comply to a number of relevant requirements of UN Regulation No. 44. The expert from Japan introduced a presentation (GRSP-66-38) showing the sled test conducted on Q dummies to check safety-belt penetration according to UN Regulation No 129 requirements. He concluded that the abdominal pressure on the belt-guide device was found to be rather high compared to CRS type approval according to UN Regulation No. 129, but that it satisfied the requirements of the UN Regulation.
28. Finally, the majority of GRSP experts, with the exception of the expert from Poland, adopted ECE/TRANS/WP.29/GRSP/2019/28, not amended. The secretariat was requested to submit the proposal as part of (see para. 26) Supplement 18 to the 04 series of amendments to UN Regulation No. 44, for consideration and vote at the June 2020 sessions of WP.29 and AC.1.
33. The expert from France on behalf of the IWG on CRS, introduced ECE/TRANS/WP.29/GRSP/2015/32 on limiting the use of booster cushions (booster seat without backrest) for children of a stature over 125 cm and on the application for type approval of these CRS only in mass Group III for children from 22 kg to 36 kg. The expert from Sweden introduced a possible alternative symbol (GRSP-58-27), to better clarify the use of this type of CRS for consumers. GRSP adopted ECE/TRANS/WP.29/GRSP/2015/32, as amended by Annex II to this report and requested the secretariat to submit the proposal for consideration and vote at the June 2016 sessions of WP.29 and AC.1 as draft Supplement 11 to the 04 series of amendments to UN Regulation No. 44.
34. The expert from the Russian Federation introduced ECE/TRANS/WP.29/GRSP/2015/33 on excluding the possibility of approval for child restraint systems with a guide strap. GRSP adopted the proposal, as amended by Annex II to this report and requested the secretariat to submit the proposal for consideration and vote at the June 2016 sessions of WP.29 and AC.1 as part of (see para. 33 above) draft Supplement 11 to the 04 series of amendments to UN Regulation No. 44.
