Installation planning
Safety Information
•
Position the wheelchair facing forward - centrally in the designated region of the
vehicle.
•
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 1). 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’. Guidance positions are shown in
Fig 2.
•
Once happy with the planned wheelchair position, lay the floor anchors in their
desired locations and check carefully immediately below the floor, that they and/or
the hole cutter will not foul brake lines, fuel tanks, chassis members etc. If in doubt
modify the wheelchair anchorage positions accordingly.
•
Note:
The fixing screw supplied with each anchor is an M10 x 60mm long, ISO
grade 12.9, zinc plated socket head cap screw. Where a different length is required
care must be taken to source a cap screw of an equal grade.
Note: seated head
height (HHT)
ranges from as low
as 1000mm for a
6-year-old child to
1550mm for a tall
adult.
