Annex 3

PROCEDURE FOR DETERMINING THE "H" POINT AND THE ACTUAL
TORSO ANGLE FOR SEATING POSITIONS IN MOTOR VEHICLES

        1. PURPOSE

         The procedure described in this annex is used to establish the "H" point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer. [5]/

2. DEFINITIONS

 For the purposes of this annex:

        2.1. "Reference data" means one or several of the following characteristics of a seating position:

        2.1.1. the "H" point and the "R" point and their relationship,

        2.1.2. the actual torso angle and the design torso angle and their relationship.

        2.2. "Three‑dimensional 'H' point machine" (3-D H machine) means the device used for the determination of "H" points and actual torso angles.  This device is described in appendix 1 to this annex;

        2.3. "'H' point" means the pivot centre of the torso and thigh of the 3‑D H machine installed in the vehicle seat in accordance with paragraph 4. below.  The "H" point is located in the centre of the centreline of the device which is between the "H" point sight buttons on either side of the 3-D H machine.  The "H" point corresponds theoretically to the "R" point (for tolerances see paragraph 3.2.2. below).  Once determined in accordance with the procedure described in paragraph 4., the "H" point is considered fixed in relation to the seat‑cushion structure and to move with it when the seat is adjusted;

        2.4. "'R' point" or "seating reference point" means a design point
