Proposal to align UN R14 with recent changes to UN R16 on occupant 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 (enhanced child restraint systems). 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.

Proposal to transfer all ISOFIX requirements from UN R14 into a new UN Regulation. Within the context of the international whole vehicle type approval program, the removal of these CRS anchorage provisions would align UN R14 with its Australian Design Rule counterpart and enable Australia to apply the revised UN R14 narrowed down to adult seat-belt anchorages only.

Per the proposal to narrow the scope of UN R14 (GRSP-60-04), this proposal would consolidate the provisions for child restraint anchorages deleted from UN R14 as a new UN Regulation.
