General requirements 1.1. Vehicles of categories L2e, L5e, L6e and L7e with a mass in running order > 270 kg shall be fitted with safety belt anchorages and safety belts on seats (i.e. not required in case of saddles), complying with the requirements of this Annex. 1.2. Vehicles of categories L2e, L5e, L6e and L7e with a mass in running order ≤ 270 kg may be fitted with safety belt anchorages and/or safety belts, provided that these comply with the requirements of this Annex. 1.3. The number of safety belt anchorages provided shall be sufficient to facilitate the correct installation of the mandatory, voluntary or optionally installed safety belt on any given seat. 1.4. Safety belt anchorages shall conform to the 7/16-20 UNF 2B thread size and tolerance specifications. 1.4.1. However, if the vehicle manufacturer has fitted safety belts as standard equipment to specific seating positions, the safety belt anchorages for those seating positions may have characteristics different from those specified in point 1.4. 1.4.2. Anchorage points complying with the specific provisions for the installation of special-type (e.g. harness-type) safety belts may have characteristics different from those specified in point 1.4. 1.5. It shall be possible to remove a safety belt without any remaining damage to the safety belt anchorage point. 1.6. The R-point of a seating position shall be determined as follows: 1.6.1. The R-point of a saddle shall be taken as declared by the vehicle manufacturer and duly justified by means of appropriate vehicle design criteria taking into account the characteristics of a 50th percentile male manikin (i.e. Hybrid III anthropomorphic test device) and its hip pivot point. 1.6.2. The R-point of a seat shall be established in accordance with the provisions in Appendix 3 to Part 2 of Annex VII to this Regulation. PART 2 Requirements applying to safety belt anchorages 1. Specific requirements for safety belt anchorages 1.1 The safety belt anchorages may be incorporated within the chassis, bodywork, seat or any other structure of the vehicle. 1.2. A single safety belt anchorage point may be used for attaching the safety belts for two adjacent seating positions. 1.3. The permitted locations of the effective safety belt anchorage points for all seating positions are indicated in Figures 11-P2-1 and 11-P2-2 and clarified below. 1.4. Position of the lower effective safety belt anchorages 1.4.1. The α 1 and α 2 angles shall lie between 30° and 80° in all normal positions of use of the seat. 1.4.2. If seats are fitted with an adjustment system and the manufacturer’s declared torso angle is less than 20°, the α 1 and α 2 angles referred to in the previous point may lie between 20° and 80° in all normal positions of use of the seat. 1.4.3. The distance between the two vertical planes parallel to the longitudinal median plane of the vehicle and passing through each of the two lower effective anchorages L 1 and L 2 of the same safety belt shall not be less than 350 mm. This may be reduced to 240 mm in the case of a centre-row rear seating position. The longitudinal median plane of the seating position shall pass points L 1 and L 2 at no less than 120 mm from those points. 1.5. Location of the upper effective safety belt anchorages 1.5.1. If a strap guide, D-ring or similar device affecting the position of an effective safety belt upper anchorage is used, that position is determined in a conventional manner by considering the position of the anchorage when the safety belt is worn by an occupant, represented by a 50th percentile male manikin, with the seat adjusted to the design position as specified by the vehicle manufacturer. 1.5.2. Points J 1 and J 2 shall be determined as follows: point J 1 is determined in relation to the R-point by means of the following three segments: — RZ : segments of torso reference line measured from the R-point upwards over a length of 530 mm; — ZX : segment perpendicular to the longitudinal median plane of the vehicle measured from point Z in the direction of the anchorage and having a length of 120 mm; — XJ 1 : segment perpendicular to the plane defined by segments RZ and ZX measured from point X forwards over a length of 60 mm; point J 2 is determined by symmetry with point J 1 about the longitudinal plane vertically crossing the torso reference line of the relevant seat. 1.5.3. A single upper effective safety belt anchorage point shall comply with the following requirements: 1.5.3.1. The upper effective safety belt anchorage point shall lie below the plane FN that is perpendicular to the longitudinal median plane of the seating position and forms an angle of 65° with the torso reference line. For rear seats, this angle may be reduced to 60°. The plane FN may therefore not be perfectly horizontal and shall intersect the torso reference line at a point D so that: . However, if S does not exceed 200 mm: DR = 675 mm. 1.5.3.2. The upper effective safety belt anchorage point shall also lie behind plane FK perpendicular to the longitudinal median plane of the seat and intersect the torso reference line at an angle of 120° at a point B so that: . If S is not less than 280 mm, the vehicle manufacturer may opt to use: 1.5.3.3. The value S shall not be less than 140 mm. 1.5.3.4. The upper effective safety belt anchorage point shall also be located behind a vertical plane that is perpendicular to the longitudinal median plane of the vehicle and passes through the R-point. 1.5.3.5. The upper effective safety belt anchorage point shall also be located above the horizontal plane passing through the point C. Point C is located 450 mm vertically above the R-point. However, if distance S is 280 mm or more and if the vehicle manufacturer did not opt to use the alternative formula for BR in point 1.5.3.2, the vertical distance of 500 mm between point C and the R-point shall apply. 1.5.3.6. More than one actual upper safety belt anchorage point may be fitted, provided that all resulting effective safety belt anchorage points meet the requirements of points 1.5.3 to 1.5.3.5. 1.5.3.7. If the height of the upper safety belt anchorage point is manually adjustable without the use of any tools, all selectable upper safety belt anchorage point positions and the resulting effective safety belt anchorage points shall comply with the requirements of points 1.5.3 to 1.5.3.5. In this case, the permitted area as defined above may be enlarged by shifting it 80 mm upwards and downwards in the vertical direction; however, the permitted area remains bounded by the horizontal plane passing through point C (See Figure 11-P2-1). 1.5.4. Anchorage points intended for special-type (e.g. harness-type) safety belts 1.5.4.1. Any additional upper effective safety belt anchorage point shall lie on the opposite side of the first upper effective anchorage point in relation to the longitudinal median plane of the seating position. In addition: — both upper safety belt effective anchorage points shall be located above the horizontal plane passing through the point C; — both upper safety belt effective anchorage points shall be located behind the transverse plane passing through the torso reference line; — where there is a single actual safety belt anchorage point (i.e. both ends of the safety belt are to be attached to a single anchorage point), this shall be located within the area common to two dihedrals bounded by vertical lines passing through the points J 1 and J 2 , and for each point forming an angle of 30° horizontally between two vertical planes which are in turn related to the two vertical longitudinal planes intersecting both J 1 and J 2 and forming an outward angle of 10° and an inward angle of 20° with those longitudinal planes. (See Figure 11-2); — where there are two separate actual safety belt anchorage points, these shall be located within each of the respective areas formed by dihedrals bounded by vertical lines passing through the points J 1 and J 2 , and for each point forming an angle of 30° horizontally between two vertical planes which are in turn related to the two vertical longitudinal planes intersecting both J 1 and J 2 and forming an outward angle of 10° and an inward angle of 20° with those longitudinal planes. (See Figure 11-P2-2). In addition, the two anchorage points shall be so located that they are no more than 50 mm apart in any direction when one of the points is mirrored in relation to the vertical longitudinal plane passing through the R-point of the seating position in question.

Strength of safety belt anchorages 2.1. Each safety belt anchorage point shall capable of withstanding the tests provided for in points 3 to 3.5.1. Permanent deformation, including partial rupture of an anchorage or the surrounding area, does not constitute failure if the required force is sustained for the specified time. During the test, the minimum distances for the lower effective safety belt anchorage points set out in point 1.4.3 and the minimum height of the upper effective safety belt anchorage points set out in point 1.5.3.5 shall be maintained. 2.2. Displacement systems fitted to seats shall be capable of being manually activated once after the tractive force is no longer applied. 3. Testing provisions 3.1. General testing provisions 3.1.1.
