Part 1 - Product Statement & Use
These User Instructions provide detailed operating instructions for the
NEXXUS wheelchair restraint & passenger harness.
Part Number Description
KFP0089/FRK Karabiner, Universal TITUS harness
NEXXUS conforms to the dynamic test requirements of ISO 10542 for
wheelchairs up to 200kg, PLUS passenger.
NEXXUS is designed to secure one forward facing wheelchair and one
passenger. It must be used in Koller Low Profile or Surface Rails (or
equivalents).
These instructions should be read thoroughly before operating the product
and retained for future use.
Note: NEXXUS is supplied with a Universal TITUS passenger harness as
standard i.e. it is fitted with a Belt Clip AND “extra” Tongue on the blue
shoulder belt. When used in standard configuration, the extra tongue is

a) Whenever possible, space of around 1300mm by 750mm should be
provided (with enough headroom) to allow wheelchair manoeuvre
and passenger comfort. Within this space, at least 650mm should
be clear from the front of the wheelchair passenger’s head forward
and 400mm clear from the back of the head rearward.
There should be no rigid vehicle components within the shaded
areas. If this is not possible, rigid vehicle components within this
area should be covered in padding that conforms with the impact
requirements of FMVSS 201, EC 74/60 or UN/ECE 21.
The shaded areas in front of and behind the occupant’s head
should where possible be completely clear of any components
(except a headrest).

Part 5 - Warnings & Maintenance
• The use of other products, other than those supplied with the
Restraint or specified for use with the Restraint may compromise
performance. Products suitable for use with this restraint include:
KFP0034 TITUS Extension Strap - accessory
KFP0061 Support Belt - accessory
3PT/STRP 3-point Strap - for use with TITUS Harness
3PT/STRP/FIX 3-point Strap - for use with TITUS Harness
• The Restraint is for FORWARD FACING wheelchairs only.
• The Restraint is for use with only one wheelchair and one
passenger at a time.
•••• DO NOT use the restraint to secure a wheelchair heavier than that
stated under Product Statement & Use.
• Restraint components including anchorages, should be replaced if
they are suspected to have been in use during an impact from
which the vehicle must be towed.
• All Restraint webbing and components should be inspected,
cleaned and maintained regularly.
• Care should be taken to prevent contamination of the webbing with
polishes, oils, chemicals and particularly battery acid, along with
procedures and materials to be used for cleaning parts of the
Restraint.
• Frayed, contaminated or damaged webbing, and broken or worn
parts should be replaced.
• Webbing should be protected from contacting sharp edges and
corners.
• Postural support belts MUST NOT be used as occupant restraints.
• Auxiliary wheelchair equipment should be effectively secured to the
wheelchair or removed and secured safely in the vehicle during
transport, so as not to break free and cause injury to vehicle
occupants in an impact.
• Items attached to the wheelchair in front of the wheelchair
occupant, other than footrests, should be removed whenever
possible and secured safely in the vehicle during transport in order
to reduce the potential for injury to the wheelchair occupant and
others in the vehicle.

Part 4 - Operating Instructions - Removing
a) Release the belt clip (when using the 3-point belt, release the
3-point belt from the shoulder belt).
b) Remove the shoulder belt by releasing the mini buckle from the
tongue (depress the orange button on the mini buckle) and holding
the webbing let it retract back.
c) Remove the lap belt by releasing the tongue from the stalk (depress
the orange button on top of the stalk) and holding the webbing let it
retract back.
d) Open the over-centre buckles (depress the red release bars) and
feed a bit of webbing through.
e) Detach the karabiners from the rings of the static straps and
remove the static straps from the wheelchair frame.
f) Unclip the rear rail clips by lifting the red double plungers and
sliding slightly forward or backward.
g) Release the wheelchair brakes and push the wheelchair forward
slightly.
h) Detach the karabiners of the front straps from the wheelchair frame.
i) Unclip the front strap rail clips by lifting the red plungers and sliding
slightly forward or backward.
11
b) Position the wheelchair, facing forward, centrally between the rails
being used. Lock the brakes.
c) Insert both front tie-down strap rail clips into corresponding holes of
adjacent rails, close enough to attach to the wheelchair, ensuring
the red plungers lock fully into rails (push down on the body of
the rail clip and slide forward / backward so they lock automatically).
d) Attach the karabiners to the wheelchair frame, either at points
indicated on the frame, or, above the wheel axles on part of the
main frame. (Karabiners can face “in” or “out”, depending on
wheelchair design and which method fits best).

e) Insert both rear tie-down strap rail clips behind the wheelchair, with
the stalk to the inside of the vehicle, ensuring the static straps (with
rings) are able to go around the wheelchair frame, and that the
double plungers lock fully into rails (push down on the rail clip
bodies and slide slightly forward / backward so they automatically
lock).
f) Pass the static straps around the wheelchair frame, so that the
rings are just fully around.
g) Open the over-centre buckles (push in red release bar) and feed
webbing through so that the webbing is long enough for the
karabiners to attach to the rings on the static belts.
h) Attach each karabiner to the ring on its corresponding static strap.
i) Pull the webbing through one over-centre buckle while closing it to
tension the system. Repeat the other side, ensuring both
over-centre buckles are locked.
Note: Depending on wheelchair design and which method fits best,
karabiners and rings can “face” in or out - see photos below.

• The angle of the lap (pelvic) belt should be within the preferred zone
of 45° to 75° to the horizontal, or the optional zone of 30° to 45° to
the horizontal.
• Lap and shoulder belts must not be held away from the body by
wheelchair components such as armrests or wheels.
• Lap and Shoulder Belts should be adjusted to fit as firmly as
possible while still allowing for occupant comfort.
• The Shoulder belt should fit over the shoulder and across the chest.
• Lap and Shoulder Belts must not be worn twisted.
Koller recommend the use of 3-point belts whenever possible. Please
refer to previous fitting of lap and shoulder belts and below.

• Upper-torso anchor or webbing guide points that are adjustable in
height should be set at or above the wheelchair occupant’s
shoulder so as not to impose downward loads on the spine in the
event of an impact.

For maximum passenger protection, belts should be fitted to individual
users and with reference to below.
• Lap and Shoulder Belts must be used together to reduce the risk of
head and chest impacts with vehicle parts.
• The extent of head and chest excursions also depends on the
location of the upper torso (shoulder) belt anchor point and may
increase as anchor point distance above and behind the occupant’s
shoulder increases.

j) Pull out the lap belt (black webbing) from the TITUS harness and fit
around the passenger’s pelvis, ensuring it does not rest over any
wheelchair parts. Clip the large tongue into the stalk until it locks in
place.
k) Pull out the shoulder belt (blue webbing) from the TITUS harness
and fit over and across the passenger’s shoulder, ensuring it does
not rest over any wheelchair parts. Clip the mini buckle into the
small lap belt tongue.
l) Release the belt clip and slide it to the bottom of the shoulder belt
so that it rests on the TITUS belt assembly cover. Pull out the
shoulder belt webbing slightly, lock the belt clip and then release
the shoulder belt (leave the “extra” tongue the belt clip as it is only
used for 3-point harness versions - see note below).
Passenger and wheelchair are now secure.
Note: If using a 3-point belt, do not use the supplied belt clip, but use the
“extra” tongue. First ensure the 3-point belt is fitted to the side of the
vehicle. Slide the extra tongue on the shoulder belt up to the passenger’s
shoulder and clip into the buckle of the 3-point belt. Adjust the length of
the 3-point belt so that the shoulder belt is lifted slightly from the shoulder.
