The tie downs have a rectangular aperture 25mm x 50mm. Any hook or loop of the restraint
end fitting must fit through this hole.
The wheelchair provides for anchoring a pelvic belt restraint that conforms to the
requirements of RESNA WC19 Section 19 and ISO7176-19. The belt anchor points are
shown in Figure 5. The seatbelt is anchored over a 14mm spigot by an M8 (minimum grade
8.8) bolt. The pelvic belt restraint can be used in conjunction with a vehicle anchored
shoulder belt with a standard lower anchorage connector as a crashworthy three point belt
restraint in motor vehicles.
Magic Mobility supply either a 600mm or 700mm compatible crashworthy wheelchair
anchored pelvic belt restraint when WC4;19/ISO7176;19 tie downs are requested. This belt
is designed to accommodate use on either side of the vehicle. The belt is equipped with
standard interconnect hardware to enable attachment of suitably equipped vehicle anchored
shoulder belts. See Figure 6. The free end of the vehicle anchored shoulder belt is installed
over the shoulder belt connection pin.
Figure 6 - The Wheelchair Anchored Pelvic Belt
The pelvic belt should be worn low across the front of the pelvis and in contact with the tops
of the thighs near the thigh-abdominal junctions.
The angle of the pelvic belt restraint should be between 30° to 75° relative to the horizontal
and, ideally between within 45° and 75° to the horizontal, as shown in Figure 7
