In June 2014, WP.29 returned a proposal (document WP.29/2014/34) to introduce provisions for ISOFIX positions in convertibles and vehicles with one seating position per row due to concerns over clarity. Given the complexity of this topic, OICA has decided to address specific elements separately. This proposal addresses the use of top tethers in child restraint systems and proposes to retain the “i-size” term and definition endorsed by GRSP.

Proposal to clarify the text related to the recently expanded height requirements for the effective upper belt anchorage (Supplement 4 to the 07 series of amendments to Regulation No. 14).

Proposal to exclude “bucket seats” from the ISOFIX requirements as well as vehicles with only one seating position (by applying the regulation only to vehicles with more than one seating position). The proposal also exempts certain vehicle/seating configurations from ISOFIX requirements, addressing cases where the vehicle design and purpose mitigate against the use of such child restraints and ISOFIX systems.

Germany submitted a proposal that would require at least one set of ISOFIX anchorages in single-row vehicles (which are currently exempted under UN R14). This proposal (superseding GRSP-55-31) would set a minimum R-point criteria for requiring the ISOFIX anchorages and thus exempt vehicles with R-points below this minimum height. The purpose is to exempt sport vehicles not intended to carry small children requiring child seats from the ISOFIX requirement.
