Véhicules routiers — Méthodes et critères pour l'évaluation de la facilité d'utilisation des systèmes de retenue enfants et leurs interfaces avec les systèmes d'ancrage dans le véhicule — Partie 4: Sécuriser l'enfant dans les systèmes de retenue pour enfant, et aspects de manipulation quotidienne

ISO 29061-4:2017 provides criteria for judgement of usability of child restraint systems (CRS) with regard to the securing of a child in the child seat and other daily handling aspects.

ISO 29061-4:2017 provides criteria for judgement of:

- ease of availability of instructions;

- clarity of instruction manual and labelling; and

- the ease of use of design related features of the CRS related to securing the child or child dummy in a CRS installed in vehicle.

ISO 29061-4:2017 can be used in conjunction with either ISO 29061-1 or ISO 29061-3 for making a complete usability evaluation of child restraint systems attached to the vehicle with ISOFIX/LATCH or vehicle seat belts.

NOTE Booster system usability evaluation, including securing of a child in the booster system, is covered by ISO 29061-5.
