Informal Group on Child Restraint Systems | Session 59 | 22 Jun 2016
Stuttgart
Agenda Item 6.
Work on UN R129 Phase III

6.1. Action plan (Principles)

For Pierre CASTAING (UTAC & Chairman); the current gabarit is for i-size products but the buckling access is not take into account. Then, we have to solve it. Can we have same provisions as B1, B2 & B3?

We agreed with the fact that the phase III is same as phase I except for the fixation of the CRS with safety belt instead of use of Isofix connectors.

We also have to handle the routing of the adult safety belt.

According to Pierre CASTAING (UTAC & Chairman), we have to found the best belt routing for phase III products and take into account the buckle access in CRS gabarit but we do not have to change the gabarit use for car manufacturer.

Question from Tommy PETTERSSON (VTI): Is it possible to add R3 gabarit for the universal position?

6.2. Installation Procedure

Phase III seatbelt use for CRS fixation (Philippe LESIRE from LAB) CRS-59-10e

The goal is to ensure that the approval of products with a complex belt routing is not possible.
From a study on the market, some “good” and “poor” belt routing where highlight for forward and rearward facing. ISO method for scoring the ease of use of CRS will be use during evaluation in July 2016.

Farid BENDJELLAL from BRITAX: do we have to take into account the car environment as new technologies (belt & bag), buckles access, buckle interaction?

For James ABRAHAM (FORD) by forcing CRS manufacturer to have kind of universal installation for belted CRS, you will impose the belt anchorage position to the car manufacturer. For Pierre CASTAING (UTAC & Chairman), pre-tensioners are not take into account and can have big influence on child safety if accident, and then we have to think about.

Ansgar POTT (HYUNDAI): this work is more relevant for the CRS manufacturer but it could be important to have frequently feedback from this subgroup.

Pierre CASTAING (UTAC & Chairman) ask to OICA : it could be good if OICA can share and give whishes about the best use of their adult safety belt, and which kind of CRS belt routing are well design or not. OICA could send these remarks and wishes to this subgroup. Does OICA have some constraints (geometry, block the buckle, block the retractor ,) to be given to the subgroup?

Pierre CASTAING (UTAC & Chairman) asks to CLEPA: could you confirm that some current products are difficult to be installed and the fact that the work from this subgroup can help the ease of use and avoid lot of misuse in the future?

Farid BENDJELLAL from BRITAX: when do have to provide this work, when is the dead line of this sub group. For Pierre CASTAING (UTAC & Chairman), it could be nice to have formal document for May 2017.
