The seat reference point(S) shall be the point  in the central longitudinal plane of the seat  where the tangential plane of the lower backrest and a horizontal plane intersect.
790 mm above and 150 mm forward of the seat reference point described in Annex III.
Seat reference point(S)'means the point  of intersection in the median longitudinal plane of the seat between the tangential plane at the base of the padded backrest
After each application or removal of the load, the suspension travel must be measured 200 mm in front of the seat reference point in the median longitudinal plane of the seat  surface.
900 mm above and 150 mm forward of the seat reference point shall be recorded.
extending forward for 400 mm from and tangential to plane 2.2.3 at a point  150 mm forward of the seat reference point;
the position at a given moment of a point  situated on the seat  surface 200 mm in front of the seat reference point in the median longitudinal plane.
The width of the seat  surface, measured perpendicular to the median plane of the seat,  150 mm in front of the seat reference point(S) and at not more than 80 mm above that point,  must be at least 450 mm see figure below.
The rear wall of the cab from 300 to 900 mm above the seat reference point must be a minimum of 150 mm behind a vertical plane which is perpendicular to the reference  plane and passes through the reference point  see Figures 2 and 3.
In the case of a tractor which can be fitted with optional seats, the tests shall be based on the combined clearance of the seat reference points for all available seat-fitting options.
the main controls must be located in front of the vertical plane passing through the seat  reference point, the seat being in a central position;
which contains the procedure for determining a reference point for seating positions in motor vehicles
