Proposal to clarify and improve provisions for

1. the belt routing and positioning of the universal child restraint system seat fixture during testing;
2. dynamic testing of the rear seat system and advanced restraint system approval; and
3. to restructure and simplify the consumer information requirements on the installation of ISOFIX child restraint systems under UN R16.

Proposal to add new CRS fixtures and otherwise align UN R16 with changes introduced through UN R129 (enhanced child restraint systems). Two “Booster Seat” fixtures (ISO/B2 and ISO/B3) were added to UN R16 to coincide with the implementation of Phase 2 of UN R129. These fixtures were developed within ISO/TC 22/SC 36/WG 2 (Child Restraint Systems) and follow the principle already established in Regulations 16 and 129 to ensure child restraint to car compatibility. An additional “Reduced-Size Rearward Facing toddler CRS” fixture (ISO/R2x) was added to facilitate compatibility in small cars/seating positions. The ISO/B2 booster seat fixture was added in the i-Size concept. Lateral facing fixtures (ISO/L1 and ISO/L2) have been upgraded.

Working draft proposal to update UN R16 in accordance with the Phase 2 development of UN Regulation Nos. 44 and 129 on child restraint systems, especially with regard to the ISO booster-seat fixtures (B2 and B3).

Working draft of document GRSP/2016/24 pursuant to the 61st CRS informal group session

This informal doc amends the draft supplement presented in document GRSP/2016/24 in order to harmonize the mass tolerances of the ISO fixtures. The proposal deletes a reference to the center of gravity and geometrical centroid. The centroid would need more information before choosing tolerances needed for certification tests.

Proposal to correct figure 2 in Annex 1B to show the referenced zones A and B, to add sentence “Non-rigid material of < 50 Shore A hardness may be removed in order to demonstrate that covered or padded rigid parts are not contacted by the head or the chest of the manikin during the test.”, and to make editorial improvements.

Proposal to update the 07 series of amendments in line with UN R129 and changes to the 06 series (Supplements 8 and 9). Two “Booster Seat” fixtures (ISO/B2 and ISO/B3) were added to UN R16 to coincide with the implementation of Phase 2 of UN Regulation No. 129. These fixtures were developed within ISO/TC 22/SC 36/WG 2 (Child Restraint Systems) and follow the principle already established in Regulations 16 and 129 to ensure child restraint to car compatibility. An additional “Reduced-Size Rearward Facing toddler CRS” fixture (ISO/R2x) was added to facilitate compatibility in small cars/seating positions. The ISO/B2 booster seat fixture was added in the i-Size concept. Lateral facing fixtures (ISO/L1 and ISO/L2) have been upgraded. The proposal also corrects figure 2 in Annex 1B to show the referenced zones A and B, to add the sentence “Non-rigid material of < 50 Shore A hardness may be removed in order to demonstrate that covered or padded rigid parts are not contacted by the head or the chest of the manikin during the test.” and makes editorial improvements.
