Corrections and clarifications to the proposed amendment to the enhanced child restraint systems regulation.

Working draft of the proposed amendments to introduce provisions for non-integral CRS (“Universal Booster” or “Specific to vehicle Booster”), incorporating all the changes agreed during the 54th (December 2013) GRSP session.

In response to a GRSP request (ECE/TRANS/WP29/GRSP/53, para. 45) concerning the configuration of Child Restraint Systems (CRS) combining a base attached to the vehicle by ISOFIX anchorages with a shell installed on the base. This shell could also be used without the base and secured by an adult safety belt. This proposal aims at allowing the type approval of this configuration according to UN Regulation No. 129 in its first phase.

Text to introduce all the modifications needed in UN Regulation No. 129 (enhanced child restraint systems (ECRS)) suggested by the experts of the informal working group on child restraint systems (IWG CRS) to extend the scope of this regulation to non-integral Child Restraint Systems (“Universal Booster” or “Specific to vehicle Booster”) (Phase 2 of the UN Regulation).

This supplement concerns child restraint systems comprised of a base fixture to which a portable shell can be attached. The base fixture is attached to the vehicle by the ISOFIX anchorages in the seating position and the shell attached to the base. However, since the shells may also be designed for use without the base fixture in a configuration where the shell is secured by the adult safety belt of the seating position, this supplement would enable type approvals under UN R129 for this configuration.
