flex the cushion and back.  At the manufacturer's request, all seat assemblies shall remain unloaded for a minimum period of 30 min. prior to installation of the 3 DH machine;

4.2. The vehicle shall be at the measuring attitude defined  in paragraph 2.11. above;

4.3. The seat, if it is adjustable, shall be adjusted first  to the rearmost normal driving or riding position, as indicated by the vehicle manufacturer, taking into consideration only the longitudinal adjustment of the seat, excluding seat travel used for purposes other than normal driving or riding positions.  Where other modes of seat adjustment exist (vertical, angular, seat-back, etc.) these will be then adjusted to the position specified by the vehicle manufacturer.  For suspension seats, the vertical position shall be rigidly fixed corresponding to a normal driving position as specified by the manufacturer;

4.4. The area of the seating position contacted by the 3 DH  machine shall be covered by a muslin cotton, of sufficient size and appropriate texture, described as a plain cotton fabric having 18.9 threads per cm2 and weighing 0.228 kg/m2 or knitted or non-woven fabric having equivalent characteristics;

 If test is run on a seat outside the vehicle, the floor on which the seat is placed shall have the same essential characteristics[6] as the floor of the vehicle in which the seat is intended to be used;

4.5. Place the seat and back assembly of the 3 DH machine so  that the centreplane of the occupant (C/LO) coincides with the centreplane of the 3 DH machine.  At the manufacturer's request, the 3 DH machine may be moved inboard with respect to the C/LO if the 3 DH machine is located so far outboard that the seat edge will not permit levelling of the 3 DH machine;

4.6. Attach the foot and lower leg assemblies to the seat pan  assembly, either individually or by using the T-bar and lower leg assembly.  A line through the "H" point sight buttons shall be parallel to the ground and perpendicular to the longitudinal centreplane of the seat;

4.7. Adjust the feet and leg positions of the 3 DH machine as  follows:

4.7.1. Designated seating position:  driver and outside front  passenger

4.7.1.1. Both feet and leg assemblies shall be moved forward in  such a way that the feet take up natural positions on the floor, between the operating pedals if necessary.  Where possible the left foot shall be located approximately the same distance to the left of the centreplane of the 3DH machine as the right foot is to the right.  The spirit level verifying the transverse orientation of the 3 DH machine is brought to the horizontal by readjustment of the seat pan if necessary, or
