The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the

11、right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internatio

12、nal Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication a

13、s an International Standard requires approval by at least 75 % of the member bodies casting a vote.

14、SO 13216-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 12, Passive safety crash protection systems. ISO 13216 consists of the following parts, under the general title Road vehicles Anchorages in vehicles and attachments to anchorages for child restraint systems: Par

15、t 1: Seat bight anchorages and attachments Part 2: Top tether anchorages and attachments Part 3, Classification of child restraint dimensions and vehicle space, is under preparation. BS ISO 13216-2:2004v Introduction This part of ISO 13216 specifies top tether anchorages and attachments: a means of

16、limiting the pitch rotation of child restraint systems (CRS) when used in conjunction with the specifications of ISO 13216-1 and which can also be used in conjunction with seat belt systems for CRS installation. The main body of this document presents a wide installation zone for top tether anchorag

17、es intended for CRS with rigid ISOFIX seat bight attachments the “ISOFIX zone” developed and evaluated in dynamic tests with CRS in combination with rigid ISOFIX seat bight attachments 1) . Annex A specifies top tether anchorage installation zones, referred to as “conventional zones”, which are comp

18、atible with current US and Canadian regulations (those required under current Australian regulations are narrower). These conventional zones are applicable to all child restraint systems intended for use with top tether attachments and can be combined with any type of lower attachments: ISOFIX, LATC

19、H or conventional seat belt attachments. The ISOFIX zones were developed in order to allow more design possibilities for locating the top tether anchorage within the vehicle structure. They are based on the conventional zones, but test results have shown that CRS with rigid ISOFIX attachments can ac

20、cept wider top tether angles than those in the conventional zones, in both the vertical and horizontal planes, without a reduction in performance. 1) The application of ISOFIX zones to child restraint systems in combination with other types of attachments (LATCH or conventional seat belt attachments

21、) had not been evaluated at time of publication. BS ISO 13216-2:2004blank1 Road vehicles Anchorages in vehicles and attachments to anchorages for child restraint systems Part 2: Top tether anchorages and attachments IMPORTANT Measures should be taken to assure that top tether anchorages positioned i

22、n the extended part of the ISOFIX zones (i.e. the portions outside the conventional zones) are used only in combination with ISOFIX child restraint systems having rigid seat bight attachments. Use of ISOFIX zones for positioning top tether anchorages could result in a positioning that is incompatibl

23、e with regulations in some countries. 1 Scope This part of ISO 13216 establishes the positioning zones, dimensions and general and static-strength requirements for top tether anchorages used together with seat bight anchorages according to ISO 13216-1 or with other systems for anchoring child restra

24、int systems (CRS) in road vehicles. It is applicable to child restraint systems intended for children with a mass of up to 22 kg. NOTE Further specifications for top tether anchorages, straps and connectors could exist in other standards and regulations. 2 Normative references The following referenc

27、 the following apply. 3.1 top tether anchorage feature located on the vehicle in a defined zone, designed to accept a CRS tether strap connector and transfer its restraint forces to the vehicle structure EXAMPLE Bar, bracket, ring, webbing loop (recessed or unrecessed).

Sufficient clearance shall be provided around each top tether anchorage to allow la

30、tching and unlatching to it (see Figure 9). 4.2 Positioning of top tether anchorage in ISOFIX zones 4.2.1 Anchorage zone determination CRF The top tether anchorage shall be located within the zone shown as shaded in Figure 1, using a child restraint fixture (CRF) in a seating position equipped with

31、ISOFIX bars (for CRF dimensions, see ISO 13216-1). The top tether anchorage shall be located more than 200 mm, but not more than 2 000 mm, from the origin of the top tether strap on the rear face of the CRF, measured along the strap when it is drawn over the seat back to the anchorage. A top tether

32、anchorage may be recessed in the seat back, provided that it is not in the strap wraparound area at the top of the seat back. The seating position shall be the seats rearmost, downmost position with the seat back in its nominal position, or else shall be the seating position recommended by the vehic

33、le manufacturer. 4.2.2 Anchorage zone determination Seating position 4.2.2.1 Subject to 4.2.2.2, that portion of the top tether anchorage designed to bind with a top tether connector shall be located within the zone shown as shaded in Figures 2 to 6 of the designated seating position for which it is

34、 installed, with reference to the H-point of a template according to ISO 6549, and such that a) the H-point of the template is located at the unique design H-point of the designated seating position, as defined in SAE J1100:1993, 2.2.11.1, at the full downward and rearward position of the seat, exce

35、pt that the template is located laterally midway between the two lower restraint system anchorages, b) the torso line of the template is at the same angle to the vertical plane as the vehicle seat in its most upright position, and c) the template is positioned in the vertical longitudinal plane that

36、 contains the H-point of the template.

At point 4, a maximum angle of 45 above the horizontal line defines the upper limit of the top tether anchorage zone. In the top view, at point 4, a maximum angle of 90 defines the limits of the anchorage zone.

39、 In the rear view, at point 4, a maximum angle of 40 defines the limits of the anchorage zone. The origin of the top tether strap (5) is located 550 mm above the CRF horizontal face (1) on the CRF centreline (6). aThe anchorage zone shall not extend by more than 100 mm under the seat, in order to al
