As regards belt anchorages, the wind screen is considered as part of the
reference zone when it is c apable of entering into static contact with the test
apparatus according to the method described in Annex II to Directive 74/60/EEC.
4.3.5. For all seating positions shown in Appendix 1 and marked with the symbol #,
each exposed seating posit ion, as defined in item 4.3.6, must be
equipped with two lower anchorages.
4.3.6. An ‘exposed seating position’ is one where there is no ‘protective
screen’ in front of the seat with in the following defined space:
— between two horizontal planes, one through the H-point and the other 400
mm above it,
— between two vertical longitudinal planes which are symmetrical in
relation to the H-point and are 400 mm apart,
— behind a transverse vertical plane 1,30 m from the H-point.
For the purposes of this requirement ‘protective screen’ means a surface
of suitable strength and showi ng no discontinuities such that, if a sphere of
165 mm diameter is geometrically projected in a longitudinal
horizontal direction through any point of the space defined above and
through the centre of the sphere, nowhere in the protective screen is there any
aperture through which the geometrical projection of the sphere could be passed.
A seat is considered to be an ‘exposed seating position’, if the
protective screens within the s pace defined above have a combined
surface area of less than 800 cm2.
4.3.7. Every seating pos ition in Appendix I marked with the symbol ,
three anchorages shall be provided unless one of the following
conditions is fulfilled:
— there is a seat or other parts of the vehicle conforming to
Paragraph 3.5 of Appendix 1 of Annex III of Directive 74/408/ EEC
directly in front; or
— no part of the vehicle is in or, when the vehicle is in motion, capable of being in the reference zone; or
— parts of the vehicle within the said reference zone comply with the energy absorbing requirements set out in Appendix 6 of
Annex III of Directive 74/408/EEC in which case two anchorages may be provided.
►M4 4.3.8. ◄ ►M4 For the folding seats or seating intended solely for
use when the vehicle is stationary, as well as all the seats ◄ of any vehicle which are not covered in items 4.3.1 to 4.3.5, ►M4 no belt anchorages are required. ◄ However, if the vehicle is fitted with anchorages for such seats, these anchorages must comply with the provisions of this Directive. In this case, two lower anchorages shall be sufficient.
