Foreword

This document was drafted in accordance with the provisions of GB/T 1.1-2020

"Directives for standardization - Part 1: Rules for the structure and drafting of

standardizing documents".

This document is Part 2 of GB/T 44083 "Road vehicles - Method and rules for the

evaluation of the usability of child restraint systems and their compatibility with vehicle

anchorages". GB/T 44083 has published the following parts:

- Part 2: Child restraint systems using vehicle belts;

- Part 3: Securing and daily maintenance of child occupants in child restraint systems;

- Part 4: Booster seat and booster cushion.

This document modifies and adopts ISO 29061-3:2017 "Road vehicles - Methods and

criteria for usability evaluation of child restraint systems and their interface with vehicle

anchorage systems - Part 3: Installation of child restraint systems using vehicle seat

belts".

Compared with ISO 29061-3:2017, this document has made the following structural

adjustments:

- RE-ARRANGE the order of terms in Chapter 3, according to the logical

relationship and order of appearance;

- RE-NUMBER the serial numbers of the tables, merging the Tables 1.1 ~ Table 1.2

and Tables 2.1 ~ Table 2.5 in ISO 29061-3:2017 into Table 1 and Table 2,

respectively.

The technical differences and reasons between this document and ISO 29061-3:2017

are as follows:

- ADD the normative reference GB 27887 (see Chapter 3), as the source of some

child restraint system related terms;

- Some terms and definitions adopt the relevant descriptions in GB 27887 (see 3.1,

3.2, 3.7, 3.14, 3.15.2), which are consistent with relevant national standards and

easy to understand;

- ADD the terms and definitions of 3.2, 3.7, 3.8 about children's harness belts, anti-

rotational devices, auxiliary anti-rotational devices, to facilitate the understanding

and use of other terms.
