(iii) Using a flat square surface with an area of 2 580 mm², apply a force of 178 N perpendicular to the back of the vehicle seat in the specific vehicle shell or the specific vehicle, first against the crotch of the ATD and then against the mid-sagittal plane of its thorax;

(iv) Position each movable surface in accordance with the instructions referred to in subsection 213.4(20) of the Motor Vehicle Safety Regulations;

(v) If shoulder and pelvic belts are provided that directly restrain the ATD, they must be attached and adjusted by tightening the belts until a 9 N force applied simultaneously using a webbing tension pull device (as illustrated in Figure 5) to the webbing at the top of each shoulder and to the pelvic webbing 50 mm on either side of the mid-sagittal plane of the torso pulls the webbing a distance of 7 mm away from the ATD;

(vi) Rotate each limb of the ATD downward in a plane parallel to its mid-sagittal plane until the limb contacts a surface of the built-in restraint system system, the specific vehicle shell or the specific vehicle. Position the limbs so that they will not inhibit the movement of the torso or head during the test.

(b) In the case of a built-in booster seat:

(i) Holding the torso upright until it contacts the seat back of the built-in booster seat, seat the ATD in the built-in booster seat so that the mid-sagittal plane of its head is vertical and parallel to the longitudinal centreline of the specific vehicle shell or the specific vehicle;

(ii) Lift the arms of the ATD as far upward as possible. Extend the legs of the ATD as far forward horizontally as possible, with its feet perpendicular to the centreline of the lower legs;

(iii) Using a flat square surface with an area of 2 580 mm², apply a force of 178 N perpendicular to the back of the vehicle seat in the specific vehicle shell or the specific vehicle, first against the crotch of the ATD and then against the mid-sagittal plane of its thorax;

(iv) Position each movable surface in accordance with the instructions referred to in subsection 213.4(20) of the Motor Vehicle Safety Regulations;

(v) The type 2 seat belt assembly used to restrain the ATD is tightened to a tension of,

(A) for the upper torso restraint, not less than 9 N and not more than 18 N, as measured by a load cell used on the webbing portion of the belt.

(B) for the pelvic restraint, not less than 53.5 N and not more than 67 N, as measured by a load cell used on the webbing portion of the belt.

(vi) Rotate each limb of the ATD downward in a plane parallel to its mid-sagittal plane until the limb contacts a surface of the built-in booster seat, the specific vehicle shell or the specific vehicle. Position the limbs so that they will not inhibit the movement of the torso or head during the test.
