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).

Proposal to introduce phase 2 amendments related to the booster seat category (booster seat with backrest) into UN R129. The text includes all modifications proposed by GRSP up to and including its 57th session (Geneva, 18–22 May 2015) as well as those of the IWG CRS up to and including its 53rd session (London, 2 September 2015). The proposal builds on the original UN Regulation No. 129, Corrigendum 1, Supplements 1, 2, 3 and 4 as well as the draft 01 series of amendments to the UN Regulation (ECE/TRANS/WP.29/GRSP/2015/24) Phase 1.

Proposal to limit the use of a booster cushion (booster seat without backrest) with children of a stature greater than 125 cm and the application for type approval of such CRS only in mass Group III for children of mass from 22 kg to 36 kg. The proposal is submitted on behalf of the CRS informal working group.

Proposal to clarify that a guide strap which constrains the shoulder strap of the adult seat belt in a position to suit the child in a child restraint system cannot be approved as a separate CRS under UN R44.

The GTR7 Informal Working Group has been preparing amendments to the regulation with regard to head restraint height, use of the BioRID test dummy, and to improve the overall text. This document provides the current draft text with open items enclosed in brackets.
