with the floor-pan. In case of tibia contact, slide the foot rearward (towards the seat) until a 5 mm clearance is obtained.
8.5.4.                        For a passenger seating position:
8.5.4.1.                   Extend each leg without displacing the thigh from the seat cushion.
8.5.4.2.                   Allow the sole of the right foot to settle on the floor-pan in-line (i.e. in the same vertical plane) with the thigh. The heel of the shoe should be in contact with the floor-pan. If the contour of the floor-pan does not permit the foot to rest on a planar surface, move the foot in 5 mm increments until the foot rests on a planar surface.
8.5.4.3.                   Allow the sole of the left foot to settle on the floor-pan in-line (i.e. in the same vertical plane) with the thigh and in the same for/aft location (alignment) as the right foot. The heel of the shoe should be in contact with the floor-pan. If the contour of the floor-pan does not permit the foot to rest on a planar surface, move the foot in 5 mm increments until the foot rests on a planar surface.
8.5.5.                        Position the dummy H-point to match the WS50M H-point coordinates (defined by paragraph 2.25. of this annex) within ±5 mm. Priority should be given to the X-axis coordinate.
8.5.6.                        Adjust the dummy rib angle as follows:
8.5.6.1.                   Adjust the dummy until the thorax tilt sensor angle reading (about the sensor y‑axis) is within ±1° of the design rib angle specified by the manufacturer.
8.5.6.2.                   Where a design rib angle is not specified by the manufacturer and the final actual torso angle determined in accordance with paragraph 7. of this annex is 23° ± 1°; adjust the dummy until the thorax tilt sensor reads -2º (i.e. 2º downwards) ± 1º (about the sensor y‑axis).
8.5.6.3.                   Where a design rib angle is not specified by the manufacturer and the final actual torso angle recorded in accordance with paragraph 7. of this annex is not 23º ± 1º; no further adjustment of the dummy rib angle is required.
8.5.7.                        Adjust the test dummy neck bracket to level the head at the closest position to 0º (as measured about the head core tilt sensor y-axis).
8.5.8.                        Proceed to the final foot and leg positioning by repeating the steps outlined in paragraph 8.4.7. of this annex for a driver seating position or the steps outlined in paragraph 8.4.8. of this annex for a passenger seating position.
8.5.9.                        Verify that 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
