to the vehicle seat structure, and the vehicle seat is already tested and approved to meet the anchorage load tests required by this Regulation for adult passenger restraint.

7.                                     INSPECTION DURING AND AFTER STATIC TESTS FOR SAFETY-BELT ANCHORAGES

7.1.                               All the anchorages shall be capable of withstanding the test prescribed in paragraphs 6.3. and 6.4. Permanent deformation, including partial rupture or breakage of any anchorage or surrounding area, shall not constitute failure if the required force is sustained for the specified time. During the test, the minimum spacings for the effective lower belt anchorages specified in paragraph 5.4.2.5. and the requirements of paragraph 5.4.3.6. for effective upper belt anchorages shall be respected.

7.1.1.                         For vehicles of category M1 of a total permissible mass not exceeding 2.5 tonnes, if the upper safety-belt anchorage is attached to the seat structure, the effective upper safety-belt anchorage shall not be displaced during the test forward of a transverse plane passing through the R point and point C of the seat in question (see figure 1 of annex 3 to this Regulation)

For vehicles other than mentioned above, the effective upper safety-belt anchorage shall not be displaced during the test forward of a transverse plane inclined 10° in forward direction and passing through the R point of the seat.

The maximum displacement of the effective upper anchorage point shall be measured during the test.

If the displacement of the effective upper anchorage point exceeds the above- mentioned limitation, the manufacturer shall demonstrate to the satisfaction of the technical service that there is no danger to the occupant. As an example, the test procedure according to Regulation No. 94 or a sled test with corresponding pulse may be carried out to demonstrate a sufficient survival space.

7.2.                               In vehicles where such devices are used, the displacement and locking devices enabling the occupants of all seats to leave the vehicle must still be operable by hand after the tractive force was removed.

7.3.                               After testing any damage to the anchorages and structures supporting load during tests shall be noted.

7.4.                               By derogation, the upper anchorages fitted to one or more seats of vehicles of category M3 and those of category M2 with a maximum mass exceeding 3.5 tonnes, which meet the requirements of Regulation No. 80, need not to comply with the requirements of paragraph 7.1. concerning compliance with paragraph 5.4.3.6.

8.                                     MODIFICATIONS AND EXTENSION OF APPROVAL OF THE VEHICLE TYPE

8.1.                               Every modification of the vehicle type shall be notified to the administrative department which approved the vehicle type. The department may then either:

8.1.1.                         consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the vehicle still
