Proposal to clarify the text of UN R14. The current text has produced differing interpretations among Technical Services with regard to which requirements apply to central seating positions in rear rows of category M₁ and N₁ vehicles and the minimum distance between two effective lower belt anchorages (L1 and L2). The proposed amendments clarify that a reduced minimum distance of 240 mm is only allowed in the case where there is only one central seating position (i.e. in a row of 3 seating positions). Rear seat rows with an even number of seats always shall have a distance of at least 350 mm. Given that it entails new requirements, the proposal is presented as a new series of amendments with transitional provisions (proposed through 2025).

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.

Proposal to consolidate provisions concerning ISOFIX top tether anchorages and i-Size seating positions removed from Regulation No. 14 in a new regulation. This change removes obstacles to the inclusion of UN R14 into Annex 4 of the future UN Regulation No. 0 of the International Whole Vehicle Type Approval (IWVTA). This document revises the working document GRSP/2017/7.

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 clarify that only a three-point safety belt is permitted in the driver position.
