Explanatory presentation to …/GRSP/2023/38 – Clarification of test bench vs. bodyshell testing

This proposal removes rebound head contact from the head acceleration requirement for all CRS.

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

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 for Supplement 5 to the 00 series of amendments (document GRSP/2016/5).

Proposal to remove references to age limits in preference for limits based on stature in the definition of “infant carrier”, to update the transitional provisions in line with the new guidelines on regulatory procedures (ECE/TRANS/WP.29/1044/Rev.2), especially concerning extensions of approvals, and to replace a reference in para. 16.11 to “vehicle approval” with “Enhanced Child Restraint Systems”.

Proposal to introduce new and modified labeling and to clarify packaging information to distinguish between forward-facing-only, rear-facing-only, and convertible CRS in order to reduce the risk of users misusing these enhanced CRS.

Proposal to introduce provisions for the approval of the booster cushion category of Enhanced Child Restraint Systems.

Proposal to clarify provisions for booster seats under the 02 series of amendments to avoid possible confusion with the provisions for booster cushions in the proposal for the 04 series of amendments (see document GRSP/2018/29). The proposal also adds a missing reference to Appendix 5 of UN R16 that defines envelopes for non-integral Enhanced Child Restraint Systems.

The 01 series of amendments to UN R129 amended the door panel geometry to create a small opening close to the seat bight. This change protected the panel from interaction with the anchorage of the adult seat belt on the test bench (added subsequently in the 02 series). Although Integral ISOFIX Enhanced Child Restraint Systems (ECRS) do not use the belt, these CRS were also required to use this new door panel geometry. This proposal amends the 02 series of amendments to require Integral ISOFIX ECRS to use the original door panel geometry with no opening (except during extensions of approvals in which the new panel geometry was used). The proposal ensures that ISOFIX ECRS designs cannot use the opening to mitigate loads to the ECRS and dummy.

Proposal to clarify provisions for booster seats under the 02 series of amendments to avoid possible confusion with the provisions for booster cushions in the proposal for the 04 series of amendments (see document GRSP/2018/29). The proposal also adds a missing reference to Appendix 5 of UN R16 that defines envelopes for non-integral Enhanced Child Restraint Systems.

Proposal to include booster cushion categories within the scope of the 03 series of amendments to UN R129.

Proposal to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019 and to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129.

Proposal to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019, to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129, and to reconcile and consolidate various references to tolerances for the internal geometry assessment.

Proposal to clarify the requirements for the type approval category of booster seats over 135 cm, to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019, to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129, and to reconcile and consolidate various references to tolerances for the internal geometry assessment.

Proposal

• to clarify the requirements for the type approval of booster seats in the over 135 cm category,
• to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019,
• to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129,
• to reconcile and consolidate various references to tolerances for the internal geometry assessment, and
• to exclude the head acceleration criterion in certain cases of contact when testing booster cushions with the larger Q-dummies, in particular the Q10, due to dummy rebound over the back of the test bench during a frontal test.

The proposal was prepared by the expert from the European Association of Automotive Suppliers (CLEPA) to clarify aspects the current procedure, formalises the assessment practice and aims to improve the transparency and consistency of Type Approval testing results.

Proposal to introduce provisions for a Digital User Guide.

Proposal to clarify provisions including the Test Report Template and Dimension Assessment Method.

Proposal to clarify that specific vehicle belted Enhanced Child Restraint Systems (ECRS) may be fitted with a support leg, top tether and lower tether attachments. This proposal also amends the existing support leg volume to improve the compatibility between the support leg volume and the Child Restraint Fixtures used for accessing the external dimensions of an ECRS.

Proposal to amend the current support leg volume to improve the compatibility between the support leg volume and the Child Restraint Fixtures used for assessing the external dimensions of an Enhanced Child Restraint System (ECRS).

Proposal to correct editorial mistakes in the adopted text of the Regulation.

Proposal to correct editorial errors in the adopted text of the Regulation.

Proposal to correct editorial errors in the adopted text of the Regulation.

Proposal for editorial corrections and to harmonize the vertical excursion limit for Q3 and Q6 dummies.

Proposal to clarify the conditions under which Enhanced Child Restraint Systems must be tested in a vehicle body shell.

Proposal to correct editorial mistakes found in the 04 series of amendments to UN R129.

Proposal to amend UN Regulation No. 129 to remove rebound head contact from the head acceleration requirement for all Child Restraint Systems. The regulation currently lacks consistency regarding whether rebound head movement is considered in testing. Variations in test bench design cause booster seats to pass in some laboratories but fail in others based solely on rebound contact. The proposal ensures consistency between different CRS types and reproducibility across laboratories with different test bench designs, and aligns with the approach in UN Regulations 94 and 137.
