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 amend the bumper test area procedures under the pedestrian safety GTR.
This proposal includes the “bumper beam measurement” in the procedure.

Proposal to introduce a definition for “bucket seat” ( front passenger seat having a non-adjustable seat back) which would be exempt from the ISOFIX anchorage requirements. The proposal also exempts certain vehicle/seating configurations from ISOFIX requirements, addressing cases where the vehicle design and purpose mitigate against the use of such child restraints and ISOFIX systems.

Proposal to clarify dynamic testing, rear seat system, advanced restraint system approval, and transitional provisions under UN R16.

Text prepared by the UN R44 Technical Services Group to clarify the regulation, including test failure parameters, CRS displacement or locking systems, seat installation color coding systems, and use of load limiting devices. The test procedure would be modified, including an increase in the applied load to exceed the maximum allowed resistance to permit sliding of the strap through the quick adjuster and through rigid parts, increased tolerances related thereto, deletion of the option for shorter shift (deemed unnecessary since it is a test on the strap, not on the complete component), and modification of drawings to improve consistency with the text.

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

Proposal to amend the regulation frontal impacts with a view towards the establishment of a new regulation on frontal impact testing for occupant restraint systems (full width rigid barrier test). The proposal increases the thorax compression criterion (ThCC) stringency to 42 mm (from 50 mm).

Proposal from the Bumper Test Area Task Force to revise the procedure for determining the bumper test area under the pedestrian safety regulation. The proposal introduces a “bumper beam” method for determining the test area and includes a September 2017 transition date.

Proposal to extend the scope of UN Regulation No. 129 to include non-Integral child restraint systems (“Universal Booster” or “Specific to vehicle Booster”) (Development Phase 2 of the UN Regulation).

Proposal for Supplement 7 to the 06 series of amendments to Regulation No. 14 and for Supplement 6 to the 06 series of amendments to Regulation No. 16 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).

Draft new Regulation prepared by the Informal Working Group on Frontal Impact to establish uniform provisions for the approval of passenger cars with regard to their occupant-restraint system performance in the event of a frontal collision.

Proposal from the Informal Working Group on Frontal Impact to increase the stringency of the Thorax Compression Criterion (ThCC) for the Hybrid III 5th female dummy in the passenger seat to 34 mm under the proposed new regulation to test the performance of occupant restraint systems in the event of a frontal collision. The transition date would be 1 September 2020.

Proposal to clarify the installation provisions for “general use” safety-belts (Annex 1B, item 12).

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.

Proposal to allow the installation of different light colours on seat-belt buckles to improve visibility. The proposal also addresses the alignment of ambient light designs in modern cars with the functional element of an occupant protection device to support its visual exposition in the vehicle compartment.

Updated proposal to clarify dynamic testing, rear seat system, advanced restraint system approval, and transitional provisions under UN R16, superseding document GRSP/2015/4.

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).
