manually adjusting device shall be readily accessible to the seated wearer and shall be convenient and easy to use.  It shall also allow the belt to be tightened with one hand to suit the wearer's body size and the position of the vehicle seat.

           6.2.3.2. Two samples of each belt adjusting device shall be tested in accordance with the requirements of paragraph 7.3.  The strap slip shall not exceed 25 mm for each sample of adjusting device and the sum of shifts for all the adjusting devices shall not exceed 40 mm.

           6.2.3.3. All the adjustment devices shall be tested for strength as prescribed in paragraph 7.5.1.  They must not break or become detached under the tension set up by the prescribed load.

           6.2.3.4. When tested in accordance with paragraph 7.5.6. the force required to operate any manually adjusting device shall not exceed 5 daN.

6.2.4. Attachments and belt adjustment devices for height

           The attachments shall be tested for strength as prescribed in paragraphs 7.5.1. and 7.5.2.  The actual belt adjustment devices for height shall be tested for strength as prescribed in paragraph 7.5.2. of this Regulation where they have not been tested on the vehicle in application of Regulation No. 14 (in its last version of amendments) relative to anchorages of safety-belts.  These parts must not break or become detached under the tension set up by the prescribed load.

6.2.5. Retractors

           Retractors shall be subjected to tests and shall fulfil the requirements specified below, including the tests for strength prescribed in paragraphs 7.5.1. and 7.5.2.  (These requirements are such that they exclude non‑locking retractors.)

           6.2.5.1. Manually unlocking retractors

           6.2.5.1.1. The strap of a safety‑belt assembly equipped with a manually unlocking retractor shall not move more than 25 mm between locking positions of the reactor.

           6.2.5.1.2. The strap of a safety‑belt assembly shall extract from a manually unlocking retractor within 6 mm of its maximum length when a tension of not less than 1.4 daN and not more than 2.2 daN is applied to the strap in the normal direction of pull.

           6.2.5.1.3. The strap shall be withdrawn from the retractor, and allowed to retract repeatedly by the method described in paragraph 7.6.1. until 5,000 cycles have been completed.  The retractor shall then be subjected to the corrosion test given in paragraph 7.2. and to the dust test given in paragraph 7.6.3.  It shall then satisfactorily complete a further 5,000 cycles of withdrawal and retraction.  After the above tests, the retractor shall operate correctly and still meet the requirements of paragraphs 6.2.5.1.1. and 6.2.5.1.2. above.

           6.2.5.2. Automatically locking retractors

           6.2.5.2.1. The strap of a safety‑belt assembly equipped with an automatically locking retractor shall not move more than 30 mm between
