Belt Restraints
When using the Spex seating system as a vehicle seat, both a pelvic belt 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 within 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-point-belt restraints should be located near
the hip opposite the shoulder over which the diagonal belt crosses and not near the midline of the
occupant
• Shoulder belt restraints should fit over the shoulders with the shoulder belt restraint midway between
the shoulder and neck.
• 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
Warning
Pelvic belt restraints should make good
contact with the front and sides of the
body near the junctions of the thighs and
pelvis and against the hips
Belt restraints must not be held away from
the body by wheelchair components such as
armrests or wheels
