Review of the discussions and supporting data towards the further development of CRS requirements under UN R129.

CLEPA proposals including changes discussed during the meeting.

Proposal to clarify UN R129. 1. Requirements for car manufacturers (Regulation No. 16, Annex 17, Appendix 1, which allows a certain zone) are NOT compatible with requirements for Child Restraint System (CRS) manufacturers (Regulation No. 129, paragraph 6.1.3.4., asks for a different zone). The adult belt is supposed to run over the angle between adult thighs (that are more “fat” and the adult pelvis (that has a bigger depth). Therefore the required zone for the Child Restraint Systems has been adapted such that the routing of the adult belt over the child restraint has to closer to the intended use and design of the adult belt.

Updated proposal being developed by the Technical Services Group and the CRS informal group for submission to GRSP in 2017.

In particular to account for CRS that can be used with more than one base.

User feedback and misuse analysis.

The Technical Services Group raises concerns over defining the stature range for non-integral child restraint systems:

1. Shoulder height will be a challenge to define due to interference with the headrest
2. Shoulder breadth in respect to side wings of the seat.

Working draft of the CRS informal group as of 15 February 2017.

Proposal for a method to assess the external dimensions of a child restraint system.

Proposal to delete the term “ISOFIX” in reference to the use of an anti-rotation device in order to enable the use of the device on all classes of specific vehicle ECRS.

Clarification proposals for ISO B2 fixture to:

1. Solve interference between cushion & seatback parts
2. Facilitate the path seatbelt path in the cushion part
3. No need to define the centre of gravity for the ISO B2.

Proposal to address non-integral CRS shield systems and booster cushions remaining under the phase 2 development of UN R129.

Proposal to define the term “Base” in child restraint modular systems, an approval label for a Universal Belted base, and an approval label for a Specific Vehicle belted base.

Child restraint fixture fitment proposal for the 03 series of amendments (Phase 3) of Regulation No. 129 in order to introduce a repeatable and reproducible procedure to assess the external dimensions of a child restraint system.

Revision 3 of document GRSP-61-17.

CRS informal group discussion document on principles to guide decisions on the authorization of child restraint systems for public use.

Proposal for an improved drawing to replace the current “Figure 3: Door panel approximate maximum intrusion – Side view”.

With each development phase (series of amendments), UN R129 has expanded its scope in terms of child restraint applications (e.g., i-Size, specific vehicle ISOFIX, i-Size booster seat, specific vehicle booster seat, etc.). Paragraph 3.2.2. requires the applicant for type approval to declare the intended application or combination of applications. CLEPA proposes new language to specify the various possible combinations and related requirements in order to maintain consistency between phases 1 and 2 and phase 3.

Consumers International proposes that no new UN Regulation No. 44 approvals be granted to non-integral group 2 or group 2/3 CRS as of [1 September 2018].

Presentation to initiate discussions on the impact of storage compartments, such as in vehicle floors, on the safe installation and use of i-Size CRS.

Comparison of UN R44-approved child seats.

Revised version of the proposal from the CRS informal working group to include provisions for universal belted and specific-to-vehicle belted child restraint systems under Phase 3 of UN Regulation No. 129.

Revised proposal for the 03 series of amendments under Phase 3 of Regulation No. 129 (GRSP-61-17 and subsequent revisions) as developed during the 67th CRS informal group session. This proposal introduces provisions for universal belted and specific-to-vehicle belted child restraint systems under Phase 3 of UN Regulation No. 129.

Working draft text for discussion within the CRS informal group.

Working draft proposal of “Phase 3” amendments (universal belted and specific-to-vehicle belted CRS) for discussion within the CRS informal group.

Working draft proposal for discussion within the CRS informal group. The text corrects wording and chapter references, clarifies test procedures, and introduces new definitions.
