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.  汽车安全带英文文献和中文翻译(7):http://www.751com.cn/fanyi/lunwen_45011.html
