Combined retractable tie-down and occupant restraints
Before installing and using the combined retractable tie-downs
with occupant restraints
•
Ensure that the wheelchair is correctly maintained and that the settings of any
adjustable parts are made according to 'Instructions for Use in Transport'.
•
Whenever possible remove any items of luggage etc that may be attached to the
wheelchair and secure or store separately during transport in order to reduce the
potential for injury to other passengers travelling in the vehicle.
•
Extra care must be exercised when using vehicle boarding aids such as passenger
lifts or ramps during the loading process. Refer to 'Instructions For Use' for
information on safe slopes.
•
Position the wheelchair facing forward - centrally in the designated region of the
vehicle. Ensure the wheelchair brakes are applied.
•
To minimise the potential for head injuries in an impact, allow a clear space of at
least 400mm behind and 650mm, (FCZ, front clear zone), in front of the head of
the wheelchair user, (Fig A). The shoulder belt anchorage must be roof or side-wall
anchored at a height level such that the belt webbing passes over the midpoint of the
occupant shoulder and at a height that is at or just above the level of the occupants
shoulders so as not to impose downward loads on the spine.
•
A height provision (HHT) ranging from 1000mm to 1550mm should be made,
depending on the size of the passenger. There should also be 200mm of clear space
either side of the wheelchair centre line. If these clear space dimensions cannot be
provided then any structure protruding into this space should be adequately padded
and comply with impact performance requirements of ECE Regulation 21 'FMVSS
201'. All vehicle padding should comply with the flammability requirements of ECE
Regulation 118 'FMVSS 302'.
Note: seated head
height (HHT)
ranges from as low
as 1000mm for a
6-year-old child to
1550mm for a tall
adult.
