Safety information
Wheelchair & occupant restraint Combined webbing tie-downs with 2 & 3 point occupant restraints

General guidance
• Wheelchair Accessories that have not been approved by the Wheelchair Manufacturer must be
removed from the wheelchair and secured in the vehicle during transport to reduce the potential for
injury. Refer to ‘Instructions For Use in Transport’ provided with the wheelchair or contact wheelchair
manufacturer for further guidance.
• These combined wheelchair & occupant restraints comply with all applicable requirements of ISO 10542,
including a 48km/h, 20g frontal impact test using a forward facing 85kg surrogate wheelchair and an ATD
(test dummy) with a mass of 76.3kg. The test dummy was restrained by both a pelvic and upper-torso
restraint. Use of a pelvic only belt may compromise the performance of the WTORS system and should
be avoided.
• If the installation is to be used with an occupant head rest anchored to the vehicle, then a vehicle-
anchored back rest must be provided to minimise rearward deflection of the wheelchair seatback,
preventing neck injury.
• Regular inspection of all parts is recommended and the equipment should be used only if all
components are in good condition.
• Warning: protect webbing from contacting sharp edges and corners. Replace equipment if the
webbing does becomes cut, contaminated or frayed.
6Combined webbing tie-downs with 2 & 3 point occupant restraints Wheelchair & occupant restraint

• Any wheelchair & occupant restraints which have been subjected to a crash situation from which the
vehicle must be towed should, in the interest of safety, be replaced.
• Do not attempt to modify the equipment. For further advice on the installation and use of this
wheelchair & occupant restraint, please contact Unwin. Please read this manual fully before use.
• Avoid contact with corrosive liquids. Care should be taken to prevent contamination of the webbing
with polishes, oils and chemicals.
• The wheelchair & occupant restraint anchorages should be installed by an experienced technician/vehicle
converter. Anchorages should not be installed into unsound materials such as corroded metal, wood,
plastic and fibre glass panels, without additional and suitable reinforcement.
• The equipment has been tested in a configuration similar to that recommended by Unwin, and any
deviation from the recommendations here is the responsibility of the installer/user. These instructions
refer use with both Unwin rails and Solo anchors, however the equipment may be used with any Unwin
proprietary rail product.

Safety information
Wheelchair & occupant restraint Combined webbing tie-downs with 2 & 3 point occupant restraints

Before installing and using the combined wheelchair & occupant restraint
• 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 400 mm behind
and 650 mm, (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 200 mm of clear space either side of the wheelchair centre line.
If these clear space dimensions cannot be provided then any should be adequately padded and comply
with impact performance requirements of ECE Regulation 21 ‘FMVSS 201’. All vehicle padding should
comply with the flammability require ments 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.
8Combined webbing tie-downs with 2 & 3 point occupant restraints Wheelchair & occupant restraint

• Wheelchair users, their carers and family are advised to check vehicle
specifications to ensure that sucient floor space is available to accommodate
the wheelchair and tie-down system. These distances are based upon the desire
to maintain clear zones for potential head excursions of occupants provided with
both upper and lower torso restraints.
• Users of heavy powered wheelchairs are also advised to check vehicle carrying
capacity. If in doubt consult the vehicle supplier for further details.
• Any airbag, as fitted to the vehicle, shall be used only as a supplementary
occupant restraint if designed to be used in combination with the Solar Quattro
and an appropriate occupant restraint.
• Installers of this wheelchair & occupant restraint should take note of any vehicle
airbag position when planning the installation. Airbags can cause serious injury if
a wheelchair-seated occupant is seated too close to an airbag position. If in doubt
contact the vehicle manufacturer or your National Automotive Regulatory Body
for advice.

Fit and use
Rail floor
1. The rail will have been installed in the vehicle in accordance
with their own and the vehicle converter’s instruction. Position
wheelchair within vehicle as required.
2. Attach the front wheelchair tie-down (not supplied as part of
this product) in accordance with its own instruction
3. Moving to the wheelchair rear, select rear webbing tie-down
so that the karabiner or hook gates face outboard from the
wheelchair, (Fig 1). If using tongue & buckle, the buckle may be
positioned facing inboard or outboard,
(Fig 2). Attach each tie down into the floor rail by aligning the
ATF (aluminium track fitting) feet with the cut-out sections of
the rail, (Fig 3). Note: the yellow plungers must face toward the
rear of the vehicle. Press down on the ribbed part of the ATF,
(Fig 3A), and push firmly down towards the wheelchair until the
yellow plunger drops and locks into the rail. If using rail lengths
giving adjustability on the positioning of the ATF, then ensure that
ATF is sited opposite each other.
4. Remove the webbing from the Velcro patch and release the
over-centre buckle.
5. Attach the karabiner / hook / tongue & buckle to the wheechair
main frame to create an angle of about 30 to 45° within the rear
view zone, (Fig 4). (Some wheelchairs which indicate this tie-
down position, Fig 5).
6. Pull the webbing through the over-centre buckle
until it is tight. With the free hand, begin to close the
buckle. Once the webbing is retained, fully close the
buckle using both hands, (Fig 6). Re-secure the Velcro
to prevent the loose end from becoming a trip hazard.
The occupant restraint must now be fitted.
Removing wheelchair tie-down:
1. Release the webbing tension in each strap by pressing
the silver release on the over-centre buckles and
detach the karabiner / hook / tongue & buckle from
the wheelchair frame. Note: in an emergency, if
using the tongue & buckle version, the tie-down can
be quickly removed from the wheelchair by simply
pressing each buckle release button. Close the over-
centre buckle and return the webbing end to the
Velctro patch.
2. Lift the yellow plunger fully and slide back away from
the wheelchair to align the ATF feet with the rail cut
outs, lift away from the rail and store securely.

Fit and use
3 point double inertia seatbelt
• Unwin recommends the use of a 3 point occupant restraint system to provide greater protection in case of an impact. However
we also recognise that some vehicle layout/designs or specific postural or medical conditions do not allow that style of seatbelts
to be used easily.
• This system is not ISO 10542 compliant if used in 2 point configuration.
• Before fitting the occupant restraint, ensure that the reversible or fixed stalk button is facing outside in relation to the wheelchair.
With the reversible stalk, if orange button faces inside, turn the stalk 180º to sit in the right position.
• In accordance with International regulations, standard Unwin occupant restraints are designed to be used for passengers weighing
22kg or above. If the passenger weighs less than 22kg, Unwin recommend that a suitable, and appropriately tested child restraint
seat is used. This may involve a secondary seat belt restraint as recommended by the original seat manufacturer.
1. Position the third point fixing into the cant rail, (Fig 8), so that it is vertically above the inertia reel
casing fixed onto the floor fixing. Unfasten the tongue and buckle.
2. Pull the black webbing upwards and unfasten the tongue from the grey webbing buckle.
3. Position the black webbing to form the lap belt and insert the tongue into the buckle stalk, (Fig 9).
4. Ensure that the lap belt lays low on the pelvis of the occupant, running as close as possible over
the hips on both sides.
5. Remove the black plastic cover on the grey shoulder belt tongue and fit into the third point fixing.
6. Position the grey webbing to form the shoulder belt and insert the buckle into the tongue.
7. Adjust the height of the shoulder belt to clear the occupant’s shoulder by approximately 25mm -
1 inch, (Fig 10).
8. The lap belt anchor points should be positioned to achieve belt angles of 30° or more to the
horizontal and preferably between 45° and 75° in order to fit low across the pelvis reducing the
possibility of the belt loading the abdomen, (Fig 7). The pelvic restraint is designed to bear upon
the bony structure of the body and should be worn low across the front of the pelvis with any
junctions between the pelvic and shoulder restraints located near the wearers hips.
Removing occupant restraint
1. Release the grey shoulder belt from
the lap belt section, then from the
third point fixing and carefully allow
the shoulder belt to return to the
retractor.
2. Disconnect the black lap belt from
the buckle stalk on the aisle side and
carefully allow the lap belt webbing
to return onto it’s retractor.
3. Connect the shoulder belt buckle
to the lap belt tongue above the
opening of the retractor box.
4. The wheelchair tie-down should
now be removed.

4. Adjust for comfort by raising the webbing on the shoulder by two finger widths, unlock
the Comfort Clip to take up the slack, then re-lock the clip so that it rests on the reel
cover.
5. The lap belt anchor points should be positioned to achieve belt angles of 30° or more to
the horizontal and preferably between 45° and 75° in order to fit low across the pelvis
reducing the possibility of the belt loading the abdomen (Fig 7). The pelvic restraint is
designed to bear upon the bony structure of the body and should be worn low across
the front of the pelvis with any junctions between the pelvic and shoulder restraints
located near the wearers hips.
Removing occupant restraint:
1. Release the Comfort Clip.
2. Release the grey shoulder belt from the
lap belt section, and carefully allow the
shoulder belt to return to the retractor.

Solo anchor
1. The Solo anchors will have been installed in the vehicle, in accordance with our own
and the vehicle converters instructions. Position the wheelchair within the vehicle as
required.
2. Attach the front wheelchair tie-down, (not supplied as part of this product), in
accordance with its own instruction. A front wheelchair tie-down should be secured
first, before any rear combined restraints are fitted.
3. Moving to the wheelchair rear, select rear webbing tie-down so that the karabiner or
hook gates face outboard from the wheelchair, (Fig 1). If using tongue and buckle, the
buckle may be positioned facing outboard or inboard, (Fig 2). Attach each tie-down
onto the rear floor anchor points by aligning the button within the cleat to the slot
on the floor anchors, (Fig 15). Slide the cleat fully home, (Fig 15), (raising the anchor
from its housing if using the retractable floor anchor), rotate the cleat through 90° to
align the karabiner/hook fixing or tongue and buckle with the wheelchair rear vertical
frame.
4. Remove the webbing from the Vecro patch and release the over-centre buckle.
Attach the karabiner/hook fixings, or tongue and buckle, to the wheelchair main
frame to create an angle of about 30-45° within the rear view zone, (Fig 4). (Some
wheelchairs will indicate this tie-down position, Fig 5). Pull the webbing through the
over-centre buckle until it is tight. With the free hand, begin to close the buckle. Once
the webbing is retained, fully close the buckle using both hands, (Fig 6). Re-secure the
Velcro to prevent the loose end from becoming a trip hazard.

Fitting and using the combined webbing tie-downs with 3 point static occupant restraint
Fit and use
1. The wheelchair tie-down should first be fitted as indicated on
page 16.
2. The occupant restraint should be installed in accordance with
section 6 and 8 notes using the supplied hardware as shown
opposite, (Fig 16). Note: if fitting hardware, other than that
provided in this kit, is to be used then the fixing bolts should be
of an equivalent cross section and an equivalent grade namely
B.S. Grade 'S' (ISO 8.8).
3. The componentry is assembed as shown opposite, (Fig 16), with
the upper 3rd point bolted to an approved anchorage position
on the vehicle body. Bolts should be tightened to a torque of
40Nm. If installing the ATF of the removable 3rd point, then
a suitable rail section, known as a cant rail, should be installed
in the vehicle. Note: all vehicle anchorage points may require
reinforcement as necessary to meet any required minimum
strength recommendations for the vehicle.
4. Install the static lap belt section - tongue side into the stalk
opposite the 3rd point anchorage, (Fig 17).
4. Install the static lap belt section - buckle side into the stalk
nearest to the 3rd point anchorage, (Fig 18).
5. Draw the two sections around the occupant's waist and clip the
lap belt adjuster into the lap belt buckle, adjusting as firmly as
possible, consistent with user comfort, so that the lap belt sits
low over the front of the pelvis and bears over the bony part of
the body.
Occupant restraints should not be held away from the body by wheelchair
components or parts, such as armrests or wheels, and should not be worn
twisted in any way. Occupant restraints should be adjusted as firmly as
possible and consistent with user comfort. Upper torso restraints should fit
over the shoulder or shoulders.
6. Disconnect the shoulder belt snap clip from its storage position,
(Fig 19), and draw across the upper body connecting it into the
static lap belt section - tongue side snap button, (Fig 20). Adjust
the shoulder belt tension to comfortably suit the user, (Fig 21).
7. The lap belt anchor points should be positioned to achieve belt
angles of 30° or more to the horizontal and preferably between
45° and 75° in order to fit low across the pelvis, reducing the
possibility of the belt loading the abdomen, (Fig 7). The pelvic
restraint is designed to bear upon the bony structure of the body
and should be worn low across the front of the pelvis with any
junctions between the pelvic and shoulder restraints located near
the wearer's hips.
Removing occupant restraint
1. Disconnect the shoulder belt snap clip from the snap button,
remove, shoulder belt from the occupant.

Fit and use
1. The wheelchair tie-down should first be fitted as indicated on
page 16.
2. The occupant restraint should be installed in accordance with
section 6 and 8 notes using the supplied hardware Fig 22).
Note: if fitting hardware, other than that provided in this kit, is
to be used then the fixing bolts should be of an equivalent cross
section and an equivalent grade namely B.S. Grade 'S' (ISO 8.8).
3. The componentry is assembed, (Fig 22), with the upper 3rd
point and lower reel anchorage points bolted to an approved
anchorage position on the vehicle body. Note: the upper 3rd
point may be reversed as required, by unclipping the buckle from
the drop link tongue, reversing, and clipping back together. The
inertia reel should be mounted at an angle of 90°/90° as viewed
in 2 planes to the road level (see inset photo opposite). The reel
and its bracketry is bolted through the vehicle and reinforced
on the underside, if required, with the 100mm diameter load
spreader plate and nyloc nut. All bolts should be tightened to a
torque of 40Nm. Note: all vehicle anchorage points may require
reinforcement as necessary to meet any required minimum
strength recommendations for the vehicle.
4. Once installed, check the free running of webbing into and out
of the inertia reel and check the 'lock up' facility of the reel by
engaging a short tug at various intervals along the extension and
retraction of the webbing in and out of the reel.
4. Adjust the drop link position at or above the shoulder height to
comfortably suit the user, and draw the running tongue across
the occupant, through the furthest arm of the wheelchair and
connect into the far side rear tie-down stalk to form a diagonal
belt, (Fig 23). Disconnect the fixed tongue from its buckle,
attached to the inertia reel, (Fig 24), pass it through the near arm
of the wheelchair and connect back into the near side rear
tie-down stalk, forming the complete lap and diagonal, (Figs 23
& 25).
5. The lap belt anchor points should be positioned to achieve belt
angles of 30° or more to the horizontal and preferably between
45° and 75° in order to fit low across the pelvis, reducing the
possibility of the belt loading the abdomen, (Fig 7). The pelvic
restraint is designed to bear upon the bony structure of the
body and should be worn low across the front of the pelvis with
