When using the Spex Seating System as a vehicle seat, both a
pelvicbelt restraint and shoulder-belt restraint must always be used.
To correctly position the belt restraints on the wheelchair occupant,
the following must be ensured:
• The pelvic-belt restraint should be worn low across the front of the
pelvis near the junctions of the pelvis and thighs.
• The angle of the pelvic-belt restraint should be between 30° to 75°
relative to the horizontal and, ideally, between 45° to 75° to the
horizontal (as shown in Figure 2).
• The belt-restraint buckle of three-point belt restraints should
be placed in contact with the occupant’s body and away from
wheelchair components.
• The junction of the shoulder-belt and pelvic-belt of three-
pointbelt restraints should be located near the hip opposite the
shoulder over which the diagonal belt crosses and not near the
midline of the occupant.
• Belt restraints should not be routed outside of the wheelchair
wheels or over the wheelchair armrests, and should not be held
away from the body by wheelchair components or parts.
• Upper torso belt restraints should fit directly over, and in contact
with, the middle of the shoulder.
• Belt restraints should be adjusted to fit as snugly as possible,
consistent with user comfort.
• Belt restraints should not be worn twisted in a manner that
reduces the area of contact of the belt webbing with the
occupant.
