Sedeži se po potrebi nastavijo na naslednji način:
Positions of test blocks before test of rear seat-backs
Položaj preskusnih blokov pred preskusom zadnjih naslonov sedežev
If the rearmost row of seats is removable and/or can be folded down by the user according to the manufacturer’s instructions in order to increase the luggage compartment area, then the seat row immediately in front of this rearmost row shall also be tested.
Če je skrajna zadnja vrsta sedežev odstranljiva in/ali jo uporabnik lahko sklopi v skladu z navodili proizvajalca, da se poveča prostornina prtljažnika, se vrsta sedežev takoj pred skrajno zadnjo vrsto prav tako preskusi.
A type 2 test block is placed on the raised test floor with its largest surface 500 × 350 mm, centrally in relation to the longitudinal axis of the vehicle and with its surface 500 × 125 mm to the front.
Preskusni blok tipa 2 se postavi na dvignjeno preskusno dno z največjo površino 500 x 350 mm na sredini glede na vzdolžno os vozila in s površino 500 x 125 mm, obrnjeno naprej.
In addition, two type 1 test blocks are positioned in accordance with paragraph 2.1 in order to perform a simultaneous test on the seat-backs (see figure 2).
Razen tega se dva preskusna bloka tipa 1 postavita v skladu z odstavkom 2.1, da se istočasno izvede preskus na naslonih sedežev (glej sliko 2).

DINAMIČNO PRESKUŠANJE NASLONOV SEDEŽEV IN PREGRADNIH SISTEMOV, KI SE UPORABLJAJO KOT SISTEMI ZA ZADRŽANJE PRTLJAGE
After the installation of the test blocks as described in paragraph 2.1 or 2.2, the passenger car body shall be decelerated or, at the choice of the applicant, accelerated such that the curve remains within the area of the graph in Annex 9, Appendix, and the total velocity change ΔV is 50 + 0/- 2 km/h.
Po namestitvi preskusnih blokov, kot je opisano v odstavku 2.1 ali 2.2, karoserija osebnega avtomobila zmanjšuje hitrost ali po izbiri vlagatelja pospešuje, tako da krivulja ostane v območju grafa iz Dodatka k Prilogi 9, skupna sprememba hitrosti ΔV pa je 50 +0/-2 km/h.
No failure shall be shown in the seat frame or in the seat anchorage, the adjustment and displacement systems or their locking devices during or after the tests prescribed in paragraphs 6.2 and 6.3.
Med preskusi iz odstavkov 6.2 in 6.3 ali po njih ne pride do okvar na okviru sedeža ali pritrdišču, sistemih za nastavitev in premikanje ali njihovih napravah za blokiranje.
Upon receiving the relevant communication that authority shall inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in annex 1 to this Regulation.

The exemption referred to in paragraph 5.1.3 shall cease to have effect on 20 October 2010.
Izjema iz odstavka 5.1.3 preneha veljati 20. oktobra 2010.
It may be extended if reliable accident statistics are available and there has been further development of restraint systems.
Njeno veljavnost je mogoče podaljšati, če obstajajo zanesljivi statistični podatki o nesrečah in je prišlo do nadaljnjega razvoja zadrževalnih sistemov.
Slide the 3-D H machine rearwards by applying a horizontal rearward load to the T-bar until the seat pan contacts the seat-back (see figure 2 of appendix 1 to this annex).
Naprava 3-D H se z delovanjem vodoravne, nazaj usmerjene obremenitve na drog T premakne nazaj, dokler se sedalo ne dotakne naslona sedeža (glej sliko 2 v Dodatku 1 te priloge).
If the seats in the same row can be regarded as similar (bench seat, identical seats, etc.) only one ‘H’ point and one ‘actual torso angle’ shall be determined for each row of seats, the 3-D H machine described in appendix 1 to this annex being seated in a place regarded as representative for the row.
Če se sedeži v isti vrsti lahko štejejo za podobne (sedežna klop, enaki sedeži itd.), se za vsako vrsto sedežev določita le ena točka H in en dejanski naklon trupa tako, da se naprava 3-D H iz Dodatka 1 te priloge, postavi na prostor, ki se šteje za značilnega za to vrsto.
‘Actual torso angle’ means the angle measured between a vertical line through the ‘H’ point and the torso line using the back angle quadrant on the 3-D H machine. The actual torso angle corresponds theoretically to the design torso angle (for tolerances see paragraph 3.2.2 below);
„dejanski naklon trupa“ pomeni kot med navpičnico skozi točko H in linijo trupa, izmerjen s kotomerom za kot naklona naslona na napravi 3-D H. Dejanski naklon trupa teoretično ustreza konstrukcijsko določenemu naklonu trupa (za dovoljena odstopanja glej spodnji odstavek 3.2.2);
Place the seat and back assembly of the 3-D H machine so that the centre plane of the occupant (C/LO) coincides with the centre plane of the 3-D H machine. At the manufacturer’s request, the 3-D H machine may be moved inboard with respect to the C/LO if the 3-D H machine is located so far outboard that the seat edge will not permit levelling of the 3-D H machine.
Sedalo in hrbtišče naprave 3-D H se postavita tako, da srednja ravnina potnika (C/LO) sovpada s srednjo ravnino naprave 3-D H. Na zahtevo proizvajalca se lahko naprava 3-D H premakne bolj navznoter glede na C/LO, če je naprava 3-D H postavljena proti zunanjosti tako, da rob sedeža ne dovoli izravnave naprave 3-D H.
