angle of10o ± 5o above the horizontal in a plane parallel to the median longitudinal plane of the vehicle.

5.3.3. Full application of the l oad shall be achieved as rapidly as possible. The belt anchorages
must withstand the specified load for not less than 0·2 second.
5.3.4. Traction devices to be used in the tests described in point 5.4 below are shown in ►M4
Annex III ◄.
5.3.5. The belt anchorages for seats for which upper belt anchorages are provided shall be tested
under the following conditions:
5.3.5.1. Front outboard seats:
The belt anchorages shall be submitte d to the test prescribed in point 5.4.1 in which the loads are
transmitted to them by means of a device reproducing the geometry of a three-point safety belt
equipped with a retractor having a pulley or strap guide at the upper belt anchorage.
▼M2
In addition, where more anchorages exist than those prescribed in Item 4.3, these anchorages
shall be subjected to the test specified in Item 5.4.5 in which t he loads are transmitted to the
anchorages by means of a device reproducing the geometry of the type of safety belt intended to be attached to these anchorages.
▼B
5.3.5.1.1. In the case where t he retractor is not attached to the required outboard lower belt
anchorage or in the case where the retractor is attached to the upper belt anchorage,
the lower belt anchorages shall also be submitt ed to the test prescribed in point 5.4.3.
▼B
5.3.5.1.2. In the cases provided for in point 5.3.5. 1.1, the tests prescribed in points 5.4.1 and 5.4.3 can be performed on two different structur es if the manufacturer so requests.
5.3.5.2. Rear outboard seats and all centre seats:
The belt anchorages shall be subjected to the test prescribed in point 5.4.2, in which the loads are transmitted to them by means of a device reproducing the geometry of a three-point safety belt without a retractor, and to the test prescribed in point 5.4.3, in which the loads are transmitted to the two lower belt anchorages by means of a devic e reproducing the geometry of a lap belt. The two tests can be performed on two different structures if the manuf acturer so requests.
5.3.5.3. When a manufacturer supplies his vehicle with safety belts, the corresponding belt anchorages may, at the request of the manufacturer, be submitted only to a test in which the loads are transmitted to them by means of a device reproducing the geomet ry of the type of belts to be attached to these anchorages.
▼M3
5.3.6. If no upper belt anchorages are provided fo r the outboard seats and th e centre seats, the
lower belt anchorages shall be subm itted to the test prescribed in 5.4.3, in which the loads
are transmitted to these anchorag es by means of a device reproducing the geometry of a lap belt.
▼B
5.3.7. If the vehicle is designed to accept other devices which do not enable the straps to be
directly attached to belt anchorages without intervening sheaves or other similar devices or
which require belt anchorages supplementary to those mentioned in point 4.3, the safety
belt or an arrangement of wires, sheaves or other similar devices representing the equipment of the safety belt, shall be attached by such a device to the belt anchorages in the vehicle and the belt anchorages shall be subjected to the tests prescribed in point 5.4, as appropriate.
5.3.8. A test method other than those prescribed in point 5.3 may be used but evidence must be furnished that it is equivalent.
