Proposal to clarify the texts related to the recently expanded height requirements for the effective upper belt anchorage (Supplement 4 to the 07 series of amendments to Regulation No. 14).

Proposal to require seat-belt reminders for all seating positions, including rear positions, and to clarify the scope of the regulation.

Proposal to introduce provisions for seat-belt reminders for all vehicle seating positions pursuant to the outcome of the Task Force on Seat-belt Reminders discussions.

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.

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.

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.

This informal doc amends the draft supplement presented in document GRSP/2016/21 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 clarify provisions concerning the second-level warning for seat-belt reminders, especially with regard to rear seat positions.

Proposal to clarify that the second level warning requirement in the 02 series of amendments to the UN R16 is dependent upon the needs of each seating position. A strict reading of paragraph 2.45. would require a second-level warning in the event of any unfastened seat-belt in a front or rear position. This proposal would clarify that the second-level warning is required depending on the individual position requirement (e.g., based on detection that a position is occupied).

Proposal to correct an oversight by adding the minimum requirement for at least a two-point lap belt (Br3, Br4m, Br4Nm) for use with rearward facing child restraints for M₃ as is already the case for M₂ vehicles.

Text to clarify how the assessment of the connection of the Safety-belt reminder system in case of removable seats has to be done.

Proposal to clarify assessment of the connection of the safety-belt reminder system in the case of removable seats.

Proposal to clarify the requirements for safety-belt reminder systems on test procedure (first and second level warning), visual warning and requirements for Seat belt Reminder of rear seat row(s).

Presentation on the proposal of amendments

Proposal to clarify:

1. how to assess safety-belt reminder connection, in the case of removable seats and
2. safety-belt reminder systems test procedure (first and second level warning), visual warning and requirements for safety-belt reminder of rear seat row(s).
