Justification of submissions GRSP/2015/20 and GRSP/2015/29 (proposals to introduce an integral fixture for lateral (lie flat, carry cot) child restraint systems).

Correction of a typo in the test speed of the Russian-language version of the regulation. The text should read 56 km/h rather than 50.

Proposal to align the definition of “i-Size” child seating used in the two regulations.

Further refinements to the formal proposal to amend UN R129 with regard to non-integral CRS. This informal document effectively updates the formal proposal in GRSP/2015/24.

Updated proposal from the CRS informal group to introduce phase 2 amendments related to the booster-seat CRS category (booster seat with backrest) into UN R129. This informal document effectively supersedes the formal proposal in GRSP/2015/31.

Proposal to strip ISOFIX CRS provisions from UN R44 and to cease all new type approvals for CRS under UN R44 from November 2016 in deference to UN R129 on Enhanced CRS.

Status report on the development of global technical regulations addressing the safety of electric vehicles.

Australian proposal to adapt UN R14 to current Australian child restraint system anchorage requirements within the context of enabling the use of UN R14 within the international whole vehicle type approval system.

Australia wishes to accept the new full-width rigid barrier crash test regulation (expected as UN R137) as an alternative to its ADR 69/00; however, Australia wishes to avoid possible confusion over the use of an airbag deactivation device (such as used to turn off an airbag when a child seat is used in the front seat). Therefore, Australia proposes to clarify the provisions of UN R16 to avoid misunderstandings or misuse of such devices along the lines of requirements found in Euro NCAP and US FMVSS 208.

Proposal to simplify the UN R16 consumer handbook information pursuant to discussions on the development of UN R129 on enhanced child restraint systems.

Proposal to amend the toxicity and flammability declarations via references to EN71 (European safety standards).

Proposal to correct a reference in UN R134, Annex 3, paragraph 3.4. The reference to paragraph 6.2.2.2. was transposed from GTR No. 13; however, it ostensibly refers paragraph 2.2 of Annex 3 in UN R134.

Background presentation on the draft amendment to the GTR on head restraints. The amendment concerns changes to head restraint height measurement, use of the BioRID test dummy, and improvements to the overall text.

Proposal to introduce provisions for a new fixture to verify space availability of universal lateral facing “lie-flat” Child Restraint Systems.

Completion of missing Integral fixtures for Regulation 129. The Universal Fixture was compatible with 39 of 40 vehicle types (97.5%) tested, but a lateral fixture (lie flat, carry cot) is needed for certain special cases.

Proposal to introduce test procedures from the US FMVSS 302 with regard to the burning behavior/flammability of materials used in child restraint systems. The proposal requests a GRSP decision on the maximum burn rate limit.

US comments on child restraint systems based upon NHTSA’s National Child Restraint Use Special Study (NCRUSS), including recommendations on their installation, use, and testing thresholds.

Presentation in support of the proposal (document GRSP-58-16) to amend the toxicity and flammability declarations via references to EN71.

Updated draft of amendments to the regulation with regard to head restraint height, use of the BioRID test dummy, and to improve the overall text. This document includes revisions made during the 58th GRSP session (December 2015).

Proposal for pictogram label to indicate that booster cushions without a backrest are only suitable for children between 125 and 150 cm tall while boosters with a backrest may be used for children from 105 cm tall.

Proposal of draft text to transpose GTR No. 7 (head restraints) into UN R17, including the draft Amendment 1 to GTR 7 addressing use of the BioRID II test dummy, backset measurement method revision, and new head restraint height thresholds.

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

Responses to questions regarding seat-belt reminders asked during the last GRSP session (May 2015) based upon various selected studies.

Proposal to introduce provisions for “deployable pedestrian protection systems in the bonnet area” (e.g., active hood systems where a pedestrian impact triggers tge hood release to allow for greater impact absorption and exterior frontal airbags).

Proposal to amend the toxicity and flammability declarations via references to EN71 (European safety standards).

Proposal to amend the toxicity and flammability provisions. This proposal runs in parallel with the proposal to amend the 00 series of amendments (document GRSP-58-32).

Proposal to clarify UN R16 provisions for the dynamic testing of rear seat systems, advanced restraint system approval and transitional provisions.

Proposal to clarify UN R16 provisions for the dynamic testing of rear seat systems, advanced restraint system approval and transitional provisions.

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 a new fixture to verify space availability of universal lateral facing “lie-flat” Child Restraint Systems.

Proposal to clarify and improve the belt routing and positioning of the universal child restraint system seat fixture during testing.

The provisions of UN Regulation No. 16 (paragraph 6.4.1.4.1.) only allow contact of the chest of the dummy driver with the steering assembly, provided that this contact fulfils certain energy-dissipation test requirements and that contact does not occur at a speed higher than 24 km/h. In response to the updated provisions of UN Regulation No. 16 which allow greater forward displacement of occupants, UN Regulation No. 17 will be updated to provide requirements on improved energy-dissipation criteria for those areas of the rear of seats and head restraints where impact of the head of the rear occupant may occur. Given the update to UN R17, this proposal would amend the scope of UN R25 (which has not been updated with regard to energy dissipation) to cover only vehicle categories M2 < 3.5 tons and N1 and mention explicitly that application to N2 and N3 vehicle categories is optional.

In response to proposals to allow greater forward displacement of occupants under UN R16 and the resulting changes in impact energy-dissipation criteria under UN R17, UN R25 (with regard to head restraints) is also subject to change. This proposal would accordingly update a reference in UN R80 to UN R25.

Revised version of the proposal (formal document GRSP/2015/9 ) to extend the scope of UN Regulation No. 129 to include non-Integral child restraint systems (“Universal Booster” or “Specific to vehicle Booster”). This version includes all corrections to the text made by the Informal Working Group on Child Restraint Systems through its September session. (The CRS informal group will discuss this version during its October session.)

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 introduce provisions to prevent the unintentional opening of rear doors while the vehicle is in motion.

Proposal to expand the application area of the energy absorption criteria for seating in order to facilitate the optimization of seat-belt load limiters by allowing limited occupant contact with these seat areas.

Changes to NCAP testing oblige the use of load limiters on safety-belts with lower threshold values that yield less thorax compression but also allow for greater forward displacement of the occupants. To address the greater forward displacement of rear occupants, UN R17 is under revision to require more stringent energy dissipation performance for those areas of the rear of seats (including the head restraints and parts mounted on the seat) where the head of the rear occupant may come into contact. UN R21 allows for alternative testing of the rear parts of seats (paras. 5.7-5.7.3. ) However, in light of the changes to UN R17, this alternative approach is no longer valid. This proposal would delete the alternate method and expands the scope of UN R21 to include testing of any parts mounted on the seats.

Proposal to introduce an integral fixture for lateral (lie flat, carry cot) child restraint systems.

Proposal to harmonize information in the airbag warning label on the correct installation of Child Restraint Systems (CRS).
