Regulation 16.08 Consolidated to Supplement 3 Part 9

Model B

(See paragraph 5.2.5. of this Regulation)

The above approval mark affixed to a vehicle shows that the vehicle type concerned has been approved in the Netherlands (E 4) pursuant to UN Regulations Nos. 16 and 52.1 The approval numbers indicate that, at the dates when the respective approvals were given, UN Regulation No. 16 included the 08 series of amendments and UN Regulation No. 52 the 01 series of amendments.

2. Arrangements of the safety-belt approval marks (See paragraph 5.3.5. of this Regulation)

The belt bearing this type approval mark is a three-point belt ("A") with a multiple-sensitivity ("m") type 4N ("r4N") retractor, in respect of which type approval was granted in the Netherlands ("E 4") under number 082439, this Regulation already incorporating the 06, 07 or 08 series of amendments at the time of approval. This belt shall not be fitted to vehicles of category M1.

1.The second number is given merely as an example.

Annex 3 - DIAGRAM OF AN APPARATUS TO TEST DURABILITY OF RETRACTOR MECHANISM

Annex 4 -DIAGRAM OF AN APPARATUS TO TEST LOCKING OF EMERGENCY LOCKING RETRACTORS

A suitable apparatus is illustrated in the figure and consists of a motor-driven cam, the follower of which is attached by wires to a small trolley mounted on a track. The cam design and motor speed combination is such as to give the required acceleration at a rate of increase of acceleration as specified in paragraph7.6.2.2. of this Regulation and the stroke is arranged to be in excess of the maximum permitted webbing movement before locking.On the trolley a carrier is mounted which can be swivelled to enable the retractor to be mounted in varyingpositions relative to the direction of movement of the trolley.When testing retractors for sensitivity to strap movement the retractor is mounted on a suitable fixed bracket and the strap is attached to the trolley.When carrying out the above tests any brackets, etc. supplied by the manufacturer or his accredited representative shall be incorporated in the test installation to simulate as closely as possible the intended installation in a vehicle.

Any additional brackets, etc. that may be required to simulate the installation as intended in the vehicle shall be provided by the manufacturer or his accredited representative.

Annex 6 - DESCRIPTION OF TROLLEY, SEAT, ANCHORAGES AND STOPPING DEVICE

1. TROLLEY

For tests on safety-belts the trolley, carrying the seat only, shall have a mass of 400 ± 20 kg. For tests onrestraint systems the trolley with the attached vehicle structure shall have a mass of 800 kg. However, if necessary, the total mass of the trolley and vehicle structure may be increased by increments of 200 kg. In no case shall the total mass differ from the nominal value by more than ±40kg

2.SEAT

Except in the case of tests on restraint systems, the seat shall be of rigid construction and present a smooth surface. The particulars given in Figure 1 of this annex shall be respected, care being taken that no metal part can come into contact with the belt.

 3.ANCHORAGES

3.1. In the case of a belt equipped with a belt adjustment device for height as defined in paragraph 2.14.6. of this Regulation, this device shall be secured either to a rigid frame, or to a part of the vehicle on which it is normally mounted which shall be securely fixed on the test trolley.

3.2. The general anchorages shall be positioned as shown in Figure 1. The marks which correspond to the arrangement of the anchorages show where the ends of the belt are to be connected to the trolley or to the load transducer, as the case may be. The anchorages for normal use are the points A, B and K if the strap length between the upper edge of the buckle and the hole for attachment of the strap support is not more than 250 mm. Otherwise, the points A1 and B1 shall be used. The tolerance on the position of the anchorage points is such that each anchorage point shall be situated at most at 50 mm from corresponding points A, B and K indicated in Figure 1 or A1, B1 and K, as the case may be. 

3.3. The structure carrying the anchorages shall be rigid. The upper anchorage shall not be displaced by more than 0.2 mm in the longitudinal direction when a load of 98 daN is applied to it in that direction. The trolleyshall be so constructed that no permanent deformation shall occur in the parts bearing the anchorages during the test.

3.4.  If a fourth anchorage is necessary to attach the retractor, this anchorage: Shall be located in the vertical longitudinal plane passing through K;

Shall enable the retractor to be tilted to the angle prescribed by the manufacturer;

Shall be located on the arc of a circle with radius KB1 = 790 mm if the length between the upper strap guide and the strap outlet at the retractor is not less than 540 mm or, in all other cases, on the arc of a circle with centre K and radius 350 mm.

4. STOPPING DEVICE

4.1. The device consists of two identical absorbers mounted in parallel, except in the case of restraint systems when four absorbers shall be used for a nominal mass of 800 kg. If necessary, an additional absorber shall be used for each 200 kg increase of nominal mass. Each absorber comprises:

An outer casing formed from a steel tube; A polyurethane energy-absorber tube;

A polished-steel olive-shaped knob penetrating into the absorber; and A shaft and an impact plate.

4.2. The dimensions of the various parts of this absorber are shown in the diagrams reproduced in Figures 2, 3 and 4.

4.3. The characteristics of the absorbing material are given in Table 1 of this annex. Immediately before each test the tubes shall be conditioned at a temperature between 15 °C and 25 °C for at least 12 hours without being used. During the dynamic testing of safety-belts or restraint systems, the stopping device shall be at the same temperature as during the calibration test, with a tolerance of ±2 °C. The requirements to be met by the stopping device are given in Annex 8 to this Regulation. Any other device giving equivalent results may be used.
