14、Standardization) is a worldwide federation of national standards bodies (ISO member bodies). 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 r
15、ight 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. Internation
16、al 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 as
17、 an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

18、O 6683 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety requirements and human factors. This second edition cancels and replaces the first edition (ISO 6683:1981), which has been technically revised. It also incorporates the Amendment ISO 6683:1981/Am
19、d. 1:1990. This corrected version of ISO 6683:2005 incorporates the following corrections. In Clause 4, reference to Clause 4 of SAE J386 has been deleted, such that the reference is made to the whole of SAE J386, and not only to that particular clause.

28、straint system seat belt assembly with anchorages 3.4 polyester fibre fibres of any long-chain synthetic polymer composed of at least 85 % by weight of an ester of a dihydric alcohol and terephthalic acid 4 Seat belt assembly The seat belt assembly components shall be in accordance with either SAE J
29、386, or UNECE R16:2000, Clause 6, but excluding 6.4. 5 Restraint system specifications 5.1 General The restraint system may consist of an adjustable seat belt assembly or an adjustable seat belt assembly with retractor. 5.2 Belt webbing The webbing shall have a minimum width of 46 mm. The belt lengt
30、h shall be adjustable for an arctic-clothed operator in the 5th to 95th percentile, in accordance with ISO 3411. The webbing shall have resistance to abrasion, temperature, mild acids, alkalies, mildew, aging, moisture and sunlight equal to or better than that of untreated polyester fibre. 5.3 Belt
31、buckle It shall be possible to release the buckle with one mittened hand in a single motion. The buckle shall remain closed until it is intentionally opened. With a force on the belt loop of 670 N 45 N, the actuation force required to open the buckle shall be at least 10 N and shall not exceed 130 N
32、. 6 Performance requirements for anchorages Anchorages shall permit the seat belt assembly to be readily installed or replaced and shall comply with the strength requirements of Clause 7. If the seat does not swivel or have a suspension system, the seat belt assembly shall be anchored to the seat or
33、 to the machine at any point within the hatched zones shown in Figure 1. If the seat does swivel or has a suspension system, the seat belt assembly shall be attached to anchorages on the seat near the rear corners of the seat cushion within the hatched zones shown in Figure 1, such that the seat bel
34、t assembly moves with the seat cushion at all times. Belts, cables or similar flexible devices may be used to transfer the seat belt assembly loads from the seat anchorages to the machine. The seat index point (SIP) shall be determined in accordance with ISO 5353. SANS 6683:2008This s tandard may on

37、gle of 60 15 from the horizontal, with the line of force approximately passing through the SIP (see ISO 5353). a) The buckled restraint system shall withstand a gradually-increased force, F (see Figure 1), of a minimum of 15 000 N for at least 10 s. The force shall be attained within not more than 3
38、0 s. The body block shown in Figure 2 may be used for the application of F. b) The length of the seat belt assembly shall not increase by more than 20 % when subjected to F. c) Permanent deformation of any system component and anchorage area is acceptable under the action of F. However, there shall
39、be no failure allowing release of the restraint system, seat assembly or seat adjustment locking mechanism. d) The belt buckle shall meet the opening force requirements of 5.2 after being subjected to F.
