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

Explanations and clarifications concerning the “one belt route” provisions.

Proposal to to clarify the single belt route principle mentioned in paragraph 3.2.2. and to restrict use of the colour green exclusively to the marking belt route indicators.

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

Proposal to:

1. Clarify the single belt route principle mentioned in paragraph 3.2.2.
2. Introduce definitions, requirements and a test procedure for lower tether anchorages
3. Restrict use of the colour green exclusively to the marking belt route indicators.

The text prepared by the Ad Hoc Group on CRS, aiming to introduce definitions, requirements and a test procedure for lower tether anchorages.

The proposed amendment does not intend to change the requirements nor the level of stringency. The footnote to paragraph 3.2.2. is added to further clarify the definition of the use of a one belt route. In its current state, the text apparently has been interpreted as to allow the use of a single belt route for each application that an Enhanced Child Restraint System (ECRS) would offer. That way, one belt route for a rearward facing ECRS (integral) and a second belt route for a forward facing (non- integral) ECRS has been introduced, making a combination of C and E.
