SINCAP MDB - C2
ES-2re 50th Percentile Male Dummy
in the Driver Seating Position
NOTE: Position the rear seat occupant (SID-IIs 5 th percentile female), if applicable, prior to
positioning the driver seat occupant (ES-2re 50 th percentile male).
A. Using the reference marks on the seat, set the driver’s seat at the mid-fore/aft, full down,
mid seat cushion angle position determined in Section 11.1S of the main MDB SINCAP
test procedure.
B. If adjustable, set the seat back angle at the manufacturer’s nominal design riding position
for a 50th percentile adult male in the manner specified by the manufacturer. If the
position is not specified, set the seat back at the first detent rearward of 25 degrees from
the vertical.
C. Upper Torso.
D. Pelvis.
Once the H-point has been determined (see APPENDIX F, “Determining the H-Point
Location”), position a calibrated ES-2re test dummy in the driver’s seat.
(1) Place the dummy in the seat such that the plane of symmetry (i.e., mid-sagittal
plane) of the dummy coincides with the longitudinal centerline marking on the
seat cushion upper surface, seat back, and head restraint of the driver’s seat.
NOTE: Move the seat and seat back rearward as necessary to get the test
dummy in the seat.
(2) Bend the upper torso forward and then lay it back against the seat back. Push
the shoulders of the dummy fully rearward.
(1) Remove the foam blocks from the pelvis flesh.
(2) Position the dummy so that it sits square and level in the seat.
(3) If the seat was adjusted in step C, repeat steps A and B to set the seat at the
mid-fore/aft position and the seat back to the manufacturer’s nominal design
riding angle.
(4) The correct position of the dummy’s pelvis may be checked relative to the H-
point determined by the H-point machine. Locate the M3 holes in the H-point
back plates at each side of the ES-2re pelvis. Position the dummy’s pelvis such
that the M3 holes are located within a circle of radius 10 mm (0.39 in.) around the
H-point location (x,z) of the H-point machine. Note that the hip point of the
dummy is located 21 mm forward of the H-point determined by the H-point
machine.
(5) Position the pelvis of the dummy such that a horizontal (lateral) line passing
through the dummy hip pivot center is perpendicular to the longitudinal center
plane of the seat. Verify that the line through the dummy H-points is horizontal
with a maximum inclination of ± 2 degrees. The dummy may be equipped with
tilt sensors in the thorax and the pelvis. These instruments can help to obtain the
desired position. If the pelvic tilt angle(Y) is not within specification (± 2
degrees), go back to step C(1) and repeat steps to re-adjust the position of the
test dummy.
