the test dummy H-point and dummy rib angle are still in accordance with paragraphs 8.4.9. and 8.4.10. of this annex respectively.  If not, repeat the steps outlined from paragraph 8.4.9. of this annex onwards.
8.5.10.                     Measure and record the final test dummy H-point position in the vehicle reference coordinate system and record the final dummy rib angle and head core tilt sensor angles.
8.5.11.                     Place both arms at the 48º detent position. In this position, each half arm bone plane of symmetry forms an angle of 48° ± 1° with the adjacent (i.e. left/right as applicable) shoulder median plane.
8.6.                              Dummy installation notes and recommendations
8.6.1.                        No distance is specified for the test dummy knee spacing. However, priority should be given to ensure:
8.6.1.1.                   At least 5 mm clearance between the knees/legs and the steering shroud and centre console;
8.6.1.2.                   A stable foot and ankle position; and
8.6.1.3.                   The legs are as parallel as possible to the mid-sagittal plane.
8.7.                              Safety-belt system
8.7.1.                        The dummy installed in accordance with paragraph 8.4. of this annex shall be restrained as follows using the safety-belt system provided for the seating position by the manufacturer:
8.7.1.1.                   Carefully place the safety-belt across the dummy and fasten as normal.
8.7.1.2.                   Remove slack from the lap section of the webbing until it is resting gently around the pelvis of the dummy. Only minimal force should be applied to the webbing when removing slack. The route of the lap-belt should be as natural as possible.
8.7.1.3.                   Place one finger behind the diagonal section of the webbing at the height of the dummy sternum. Pull the webbing horizontally forward and away from the chest, and utilizing the force provided by the retractor mechanism only, allow it to freely retract in the direction of the upper anchorage. Repeat this step three times.

Description of the three-dimensional H-point machine [15] (3‑D H machine)

               1.  Back and seat pans
The back and seat pans are constructed of reinforced plastic and metal; they simulate the human torso and thigh and are mechanically hinged at the H‑point. A quadrant is fastened to the probe hinged at the H-point to measure the actual torso angle. An adjustable thigh bar, attached to the seat pan, establishes the thigh centreline and serves as a baseline for the hip angle quadrant.

2.                                  Body and leg elements
Lower leg segments are connected to the seat pan assembly at the T‑bar joining the knees, which is a lateral extension of the adjustable thigh bar.  Quadrants are incorporated in the lower leg segments to measure knee angles.  Shoe and foot assemblies are calibrated to measure the foot angle. Two spirit levels orient the device in space.
