the load bearing area, and at which compliance with the appropriate Australian Design Rules has been or can be established.

   GROSS VEHICLE MASS (GVM) - the maximum laden mass of a motor vehicle as specified by the 'Manufacturer'.

   GROUND CLEARANCE - the minimum distance to the ground from the under side of a vehicle excluding unsprung mass, flexible mudguards or mudflaps, flexible underbody aerodynamic aids and flexible underbody covers or trays.

         Note : Underbody components that do not reduce the service life of road infrastructure as a result of contact will be considered to be flexible underbody components.

   GROUP GROSS AXLE LOAD RATING (GGALR) - the least of the values allowed by 'GALR', Table 1 of ADR 38/... or that determined by 'Gross Trailer Mass'.

   H POINT - the point simulating the actual pivot centre of a human torso and thigh as determined by SAE J826 November 1962 or J826 APR80 - "Manikins for Use in Defining Vehicle Seating Accommodation".

   HARNESS BELT -A 'Seatbelt Assembly' consisting of at least one 'Strap' designed to provide pelvic restraint and 2 or more torso 'Straps' designed to provide upper torso restraint.

   HARNESS TORSO ANCHORAGE - an 'Anchorage' designed to facilitate upper torso restraint using a harness assembly.

   HEAD IMPACT AREA - all non-glazed surfaces of the interior of a vehicle that are statically contactable by a 165 mm diameter spherical head form of a measuring device having a pivot point to "top of head" dimension infinitely adjustable from 740 mm to 835 mm in accordance with the following procedure, or its graphic equivalent:
   (1) At each designated seating position, place the pivot point of the measuring device:
   (a) For 'Seats' that are adjustable fore and aft, at the 'Seating Reference Point' and a point 127 mm horizontally 'Forward' of the 'Seating Reference Point' and vertically above the 'Seating Reference Point' an amount equal to the rise which results from either a 127 mm 'Forward' adjustment of the 'Seat' or 19 mm; and
   (b)  For 'Seats' that are not adjustable fore and aft, at the 'Seating Reference Point'.
   (2) With the pivot point to "top of head" dimensions at each value allowed by the device and the interior dimensions of the vehicle determine all contact points above the lower windscreen glass line and 'Forward' of the 'Seating Reference Point'.
   (3) With the head form at each contact point, and with the device in a vertical position if no contact point exists for a particular adjusted length, pivot the measuring device 'Forward' and downward through all arcs in the vertical planes to 90 degrees each side of the vertical longitudinal plane through the 'Seating Reference Point', until the head form contacts an interior surface or
