Proposal to add provisions for the definition and requirements for lower tether strap and the definition and specifications of Lower Tether Anchorages (LTA).

Proposal from Spain on behalf of the Technical Services Group (TSG) on UN R129 to require that the shoulder strap positioner, if any, and the buckle open independently of each other in order to satisfy the requirement that the buckle can be opened by a single action. Currently, if the shoulder strap positioner has not been opened, it is possible that the buckle cannot be opened.

Proposal from Spain on behalf of the Technical Services Group (TSG) on UN R129 to restrict iSize booster seats (Non-integral Enhanced Child Restraint Systems) to occupants with a maximum stature of 135 cm in order to satisfy the plug and play principle. Presently, UN R129 would allow for approval of such CRS for children up to 150 cm.

Proposal from Spain on behalf of the Technical Services Group (TSG) on UN R129 to allow the head of the dummy to pass the DE plane provided there is a structure (e.g., head pad or backrest) that provides adequate protection for the head. Under UN R129, the combination of a stiffer test bench foam and the design of the test dummy can mean that when testing forward-facing child restraints (including boosters), the dummy’s head often passes the DE plane. The Q-series dummies are not proven to be biofidelic during the rebound phase of the impact test. In such cases, the head pad or backrest provides protection to the child’s head and the energy-absorption properties of this structure will have been tested using the test method described in UN Regulation No. 129.
