Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. Chapters 4, 5, 8 and 9 of this standard are mandatory and the others are recommendatory. This standard was drafted on basis of "Directives for Standardization-Part 1: Structure and Drafting of Standards" (GB / T 1.1). This standard is modified in relation to "Uniform Provisions Concerning the Approval of Restraining Devices for Child Occupants of Power-Driven Vehicles (Child Restraint Systems)" (ECE R44) (revision 2) and all subsequent supplement and corrigenda. The comparison table of chapter and article numbers in this standard and those in ECE R44 are listed in Appendix A. The technical differences and their reasons between this standard and ECE R44 are listed as follows: -The definition of "built-in child restraint system" (3.54) was added to specify the meaning of built-in child restraint system mentioned in ECE R44; -The ISOFIX anchorages system sketch map (Figure 1) was added for the clear understanding of the users of this standard. The following editorial changes are made to this standard: -The standard name was revised as "Restraining Devices for Child Occupants of Power-driven Vehicles"; -The definition of "ISOFIX anchorage" in Article 2.1 of ECE R44 was compiled in article 3.23 of this standard according to the expression method of GB / T 1.1; -The contents concerning "child restraint system groups and category" in Article 2.1.1 of ECE R44 was compiled in Article 4.1 of this standard according to the expression method of GB / T 1.1; -Due to the difference between Chinese approval management system and that of Europe, the relevant approval management procedures and conformity of production in ECE R44 should not be adopted; therefore, the definitions of Article 2.38 "type approval test", Article 2.39 "production qualification test" and Article 2.40 "routine testing" in Chapter 2, definitions of Chapter 3 "application for approval" and Chapter 5 "approval", requirements of "the test reports of type approval and of production qualification shall include the inspection of existing certificate mark, installation instructions and instructions for use" in Article 9.1 of Chapter 9, Chapter 10 "modifications and extension of approval of a type of child restraint system", Chapter 11 "production qualification", Chapter 12 "conformity of production and routine tests", Chapter 13 "penalties for non-conformity of production", Chapter 14 "production definitely discontinued", Chapter 16 "names and address of technical services responsible for conducting approval tests, and of administrative departments", Chapter 17 "transitional provisions", Appendix 1 "communication for approval granted, approval refused, approval withdrawn or production definitely discontinued of restraining devices for child occupants of power-driven vehicles, pursuant to Regulation No. 44.", Appendix 2 "arrangements of the approval mark", appendix 14 "type approval scheme" and Appendix 16 "control of conformity of production" were deleted. The Appendixes B to M and Appendixes Q to X of this standard are normative, Appendix A and Appendix P are informative. This standard was proposed by the National Development and Reform Commission. This standard is under the jurisdiction of the National Automotive Standardization Technical Committee (SAC/TC 114).

The structures of anti-rotation devices for different category of child restraint system are different: - An anti-rotation device for an ISOFIX universal child restraint system consists of the ISOFIX top tether strap and its anchorages; - An anti-rotation device for an ISOFIX semi-universal child restraint system consists of a top tether and its anchorages, the vehicle dashboard or a support leg intended to limit the rotation of the restraint during a frontal impact. Note: For ISOFIX, universal and semi-universal, child restraint systems the vehicle seat itself do not constitute an anti-rotation device. 3.29 ISOFIX top tether anchorage It means a feature fulfilling the requirements of GB 14167, such as a bar, located in a defined zone, designed to accept an ISOFIX top tether strap connector and transfer its restraint force to the vehicle structure.

——座椅结构件的形状、尺寸和材料； ——座椅调节机构和锁止机构的型式和尺寸； ——座椅上安全带的固定装置、座椅固定装置和车辆中与固定座椅有关部件的型式及尺寸。 3.40 位移系统 displacement system 为便于乘员的出入或货物的装卸，能够使成人座椅整体或座椅的一部分转动或纵向移动的系统，但该系统不能在中间过渡位置固定座椅。 3.41 锁止系统 locking system 使成人座椅或座椅部件保持在某个使用位置的系统。 3.42 安全带锁止装置 lock-off device 用于锁住并防止成人安全带织带的一部分相对另一部分发生移动的装置。该装置可以作用于成人安全带的肩带或腰带部分或者同时作用于两部分。 3.42.1 A类装置 class A device 当用成人安全带直接约束儿童时，能防止儿童把织带从卷收器中拉出造成腰带松弛的装置。 3.42.2 B类装置 class B device 当用成人安全带约束儿童约束系统时，使成人乘员安全带的腰带部分保持适当张力的装置。该装置还能防止织带从卷收器中滑出，造成织带拉力松弛，导致约束系统处于非最佳使用状态。 3.43 特殊需要约束系统 special needs restraint 是为那些具有特殊需要的儿童，比如有身体或智力障碍的儿童专门设计的约束系统。该装置特别允许附加的约束装置用于儿童的任何部位。 3.44 ISOFIX连接装置 ISOFIX attachment 从ISOFIX儿童约束系统结构中伸出，与ISOFIX的车辆下部固定点配合使用的连接装置。 3.45 ISOFIX儿童约束系统 ISOFIX child restraint system 具有国际通用的儿童约束系统固定装置(ISOFIX)的儿童约束系统。 3.46 座椅分缝线 seat bight 紧靠车辆座椅的座垫与座椅靠背相交线的区域。 3.47 车辆座椅固定检具 vehicle seat fixtlife(VSF) 根据ISOFIX尺寸类别确定的一套装置，其尺寸在GB 14166中给出，儿童约束系统制造商据此决定ISOFIX儿童约束系统合适的尺寸及ISOFIX连接装置的位置。 3.48 ISOFIX上部连接件 ISOFIX top tether connector 与车辆上的ISOFIX上部固定点连接的装置。 3.49 ISOFIX上部固定钩 ISOFIX top tether hook 一种典型的ISOFIX上部连接件，用于把ISOFIX上拉带安装到ISOFIX上固定点。 3.50 ISOFIX上拉带 ISOFIX top tether strap 由ISOFIX儿童约束系统上部伸出到ISOFIX上固定点之间的织带，带有一个调节装置，一个张力解除装置和一个ISOFIX上部连接件。 3.51 ISOFIX上部连接装置 ISOFIX top tether attachment 保证ISOFIX上部约束带连接ISOFIX儿童约束系统的装置。 3.52 张力释放装置 a tension relieving device 用于释放ISOFIX上拉带张力的装置。 3.53 成人安全带导向机构 adult safety-belt webbing guide 确保安全带按照正确方向顺畅移动的机构。 3.54 内置式儿童约束系统 built-in child restaint system 作为车辆或座椅的组成部分，并固定在车辆上的儿童约束系统。 4 一般要求 4.1 儿童约束系统的分组 4.1.1 儿童约束系统分为五个“质量组”： ——0组儿童约束系统用于体重小于10 kg的儿童； ——0＋组儿童约束系统用于体重小于13 kg的儿童； ——Ⅰ组儿童约束系统用于9 kg～18 kg的儿童； ——Ⅱ组儿童约束系统用于15 kg～25 kg的儿童； ——Ⅲ组儿童约束系统用于22 kg～36 kg的儿童。 4.1.2 按国际通用的儿童约束系统固定装置(ISOFIX)设计的儿童约束系统按照GB 14166的规定分为7种尺寸类别： ——A-ISO/F3类为全高度前向的初学走路孩子用儿童约束系统； ——B-ISO/F2类为降低高度前向的初学走路孩子用儿童约束系统； ——B1-ISO/F2X类为降低高度前向的初学走路孩子用儿童约束系统； ——C-ISO/R3类为全尺寸后向的初学走路孩子用儿童约束系统； ——D-ISO/R2类为缩小尺寸后向的初学走路孩子用儿童约束系统； ——E-ISO/R1类为后向的婴儿用儿童约束系统； ——F-ISO/L1类为左侧向的儿童约束系统(便携床)； ——G=ISO/L2类为右侧向的儿童约束系统(便携床)。 4.1.3 儿童约束系统质量组与ISOFIX尺寸类别对应关系如表1。 |
