'Seats' designed for one seating position only, it may be the longitudinal plane through the geometric centre of the 'Seat'.
   (II) Front passenger's 'Outboard Seating Position' on a 'Seat' which also provides for the driver's seating position - the vertical plane parallel to the 'Seating Reference Plane' of the driver's seating position and equidistant from the centre of the vehicle.
   (III) 'Seats' designed for one seating position only - the vertical plane through the geometric centre of the 'Seat', except that in the case of the front passenger 'Outboard Seating Position', it may be the vertical plane parallel to the 'Seating Reference Plane' of the driver's seating position and equidistant from the centre of the vehicle.
   (IV) Other seating positions - the plane nominated by the a 'Manufacturer' provided that in the case of an 'Outboard Seating Position' on a transverse 'Seat' which is designed for 2 occupants only, it shall be at least 200 mm from the vertical longitudinal plane through the centre of the vehicle and at least 200 mm from the inner panel (or the line of the inner panel) when measured horizontally on a transverse line through the 'Seating Reference Point'.

   SEATING REFERENCE POINT (SRP) - the 'Manufacturer's' design reference point which:
   (a) establishes the rearmost normal design driving or riding position for each designated seating position in a vehicle;
   (b) has co-ordinates established relative to the designed vehicle structure;
   (c) simulates the position of the pivot centre of human torso and thigh; and
   (d) is the reference point employed to position the 2-dimensional templates described in SAE document J826, "Manikins for Use in Defining Vehicle Seating Accommodation", November 1962; SAE J826a-August 1970; SAE J826b-January 1978; or SAE J826 APR80.

   NOTE: Some difficulties are known to exist in the interpretation of the term "rearmost normal design driving or riding position" in respect of 'Seats' with vertical adjustment and/or capabilities for extended 'Rearward' adjustment.  The following 3 clarifying points are to be used in conjunction with the definition:
   (i) in nominating the 'SRP', the 'Manufacturer' shall give consideration to all modes of adjustment of the 'Seat' - horizontal, vertical and tilt - for the purposes of establishing the "rearmost normal design driving or riding position"
   (ii) the 'SRP', once determined, is the point used to position the 2-dimensional template with the 90th percentile leg as described in the SAE document, for all purposes for which the template is used;
   (iii) the 2-dimensional template with the 95th percentile leg with dimensions as specified in SAE J826b - January 1978 shall be accepted.

   SECOND ROW SEAT(S) - that row of front-facing 'Seats' which lies immediately to the rear of the front (first) row 'Seats'. 'Seats' are considered to be
