SPEX BACK SUPPORT USER MANUAL 2WWW.SPEXSEATING.COM

Introduction

The Spex range of Back Supports are designed to accomplish comfort and function for the wheelchair user

who requires specic Back Support. The Back Support can be adjusted in many ways to meet positioning

and postural needs including the unique contouring system that enables the surface of the Back Support

to change to suit the anatomy of the user.

Spex recommends that a clinician such as an Occupational or Physiotherapist who is skilled in wheelchair

seating and positioning be consulted to determine if the Back Support is appropriate for the user.

All changes made to the Back Support should be noted in the Product Log Form on page 16 of this user

manual. The 6 Month Checklist, found in this user manual (page15), is required to be completed to ensure

the backrest is maintained in a safe and functional condition.

Contraindications

1. Use of Spex Wheelchair seating products may aect the center of gravity causing the Wheelchair

to tip, potentially causing injury. Always judge the need for anti-tippers or amputee axle adapter

brackets to be added to the Wheelchair to increase stability.

2. Check regularly for for skin redness and that pressure spots are not developing. If your skin develops

redness, stop using the product and consult your doctor or therapist.

SPEX BACK SUPPORT USER MANUAL 4WWW.SPEXSEATING.COM

RISK OF ACCIDENT, INJURY, PAIN OR DEATH IF WARNINGS ARE NOT HEEDED

Seek assistance if you are uncertain about any of the following points

1. When installing a Back Support on to a wheelchair this may aect the centre of gravity and may

cause the wheelchair to tip backwards potentially resulting in injury or death. Always assess

for the potential need for anti-tippers to be added to the wheelchair to help increase stability.

2. Installation and adjustment of your Spex Back Support should be performed only by an au-

thorized dealer, qualied therapist or seating technician.

3. Failure to use the appropriate equipment for restraint in a vehicle can result in serious injury or

death.

4. The Back Support is shipped out with the brackets attached loosely. It is the installer’s respon-

sibility to ensure all hardware is tightened and the Back Support is locked rmly in place and

the quick release latches engaged correctly before the wheelchair is used.

5. Always ensure that the quick release latches are engaged correctly at all times. If the quick

release latches are not engaged, the Back Support may detach and cause injury.

6. Only use genuine Spex installation mounting hardware (as supplied) when installing the Back

Support to the wheelchair. If the wheelchair design is such that the Back Support attachment

hardware cannot be tted, phone your dealer for further installation options.

7. Do not use the Back Support to push or lift the wheelchair. Improper use may cause the back to

detach from the wheelchair resulting in damage.

8. Only use genuine Spex accessories, components and attachments to this Back Support.

9. Do not attach the Back Support to the wheelchair with the user still sitting in the wheelchair.

10. Never use your Back Support if any hardware is missing, malfunctioning, or broken. Seek quali-

ed assistance with any repairs, replacements or adjustments.

11. The Spex Back Support range has been specically designed as a rigid Back Support for us-

ers in mobility wheelchairs. Do not use the Back Support in any way not described and never

modify the Back Support.

12. Never use the Back Support without its cover. Care should be exercised near open ame or

burning cigarettes. Using the Back Support without its cover increases the risk of ammability

and skin damage.

13. Never exceed the weight capacity of your Back Support or the wheelchair as specied by the

wheelchair manufacturer.

14. Never perform exercise weight training that causes the user to exceed the weight capacity of

the wheelchair.

15. Care must be taken when undertaking a user transfer from the seating system. The user may

fall from the wheelchair or injure themselves when supports are removed.

16. Be aware of the pinch points. Ensure all body parts are kept clear during these movements and

adjustments.

Installing Quad Mount

The Back Support shell should be able to freely move between

the wheelchair canes, with approximately 0.5” (12mm) of clear-

ance between the cane and pins on each side.

The nal adjustments should be made later during the set-up.

Apply enough tension to the fasteners to prevent the brackets

from moving freely during the set-up, and use a coarse ad-

justment to achieve the intended desired height of the Back

Support.

Tools required: 4mm, 5mm Hex (Allen) Key

Note: The upper and lower pins that connect the Back

Support to the wheelchair canes have distinct dier-

ences. These must always be set in the right method:

A. Lower pin (with at edges on shank)

B. Upper pin (with round shank)

If a custom sized Back Support has been ordered, it

may not have the slots present. If so, mount the hard-

ware in the second row of holes from the outer edge.

Lightly attach all clamps to the wheelchair frame so they

can be raised or lowered but not so loosely they fall to

the bottom of the wheelchair frame.

Quick-release lever must be pointing downwards.

AJDUST BRACKETS TO ENSURE THERE IS CLEARANCE

BETWEEN THE PIN AND THE CANE. APPLY TENSION TO

THE FASTENER TO PREVENT BRACKET FROM MOVING

FREELY DURING THE SETUP

ENSURE THERE IS APPROXIMATELY 12mm OF CLEARANCE

PER SIDE, BETWEEN THE LOCATING PIN AND THE CANE TO

ALLOW THE BACKREST SHELL TO MOVE FREELY BETWEEN

THE WHEELCHAIR CANES

To mount the hardware, partially insert one fastener,

slide the clamping plate under the fastener head, and

then secure with the remaining fastener.

Tighten both fasteners until the hardware remains in

place.

Level both left and right lower hook hardware compo-

nents.

SPEX BACK SUPPORT USER MANUAL 7WWW.SPEXSEATING.COM

Place the lower locating pins in the bottom hooks, and position

the Back Support in the upright position.

Loosen the upper Back Support bracket enough to be able to

slide it up or down, to locate the locking pin inside the quick

release catch.

Ensure the catches have engaged on the top connection pins.

Ensure the Back Support is aligned squarely, with even space

either side of the Back Support and canes.

Tighten the cane mount fasteners. Spex recommends 5 Nm of

torque.

10.

11.

If further angle alignment is required, use the extension

bracket #1259-2450-100.

The quick release mechanism should be removed from

the clamping bracket, and reattached to the extension

bracket.

The bracket can then be reattached using the M6 x 12

fasteners and Slim T-Nuts included with the extension

bracket.

To release the Back Support, rst hold the top of the

Back Support, then lift the locking levers to disengage

the latch mechanism.

Lift the Back Support away from the wheelchair.

12.

13.

14.

Adjust the location of the pins to adjust the angle and seat

depth of the Back Support, and tighten once in correct position.

Spex recommends 5 Nm of torque.

Before use, always check that the quick release latches are prop-

erly engaged.

WARNING

Installing Single/Dual Mount

Adjust the Back Support mounting brackets to allow the Back

Support to move freely between the wheelchair canes.

Approximately 5/8” (16mm) of clearance between the cane and

pin is required.

Apply enough tension to the fasteners to prevent the brackets

from moving freely during the set-up.

Tools required: 4mm, 5mm Hex (Allen) Key, 13mm spanner/

wrench.

4. Attach the brackets to the canes, using the clamps and

fasteners.

Partially insert the rear fastener, slide the clamp under-

neath fastener head, and insert and tighten both fasten-

ers to secure the bracket in place.

Ensure that both the left

and right hardware compo-

nents are level.

Tighten both fasteners.

Spex recommends 5Nm (4

ft-lb) of torque.

Note the dierences between the left and right hardware con-

gurations. Ensure the hardware is installed to the correct side.

Spex recommends that all fasteners be checked for wear, such as loose bolts or broken components every

6 months. Loose fasteners should be retightened according to the installation instructions. Contact your

authorized Spex Seating supplier immediately to replace any broken components. Do not continue to use

the system after identifying loose or broken components. For any questions regarding cleaning procedures,

contact your authorized Spex Seating dealer. The expected lifetime of the Back Support is 5 years.

Spex recommends using AHP (Accelerated Hydrogen Peroxide) disinfectant wipes. The disinfection product

must be used as per the manufacturer instructions. Spex takes no responsibility for the eectiveness of the

disinfecting process.

Cleaning the Spex/Vigour Backrest upholstery cover

Remove cover by carefully pulling from the Velcro on the back shell. Locate zipper on the cover and unzip.

Remove the inner foam section and turn cover inside out. Zip cover closed to avoid snagging. Machine

wash in warm water 40° C / 104° F. Drip or tumble dry on low heat. Do not iron, bleach or dry clean. If

chemical cleaners are used, covers must be rinsed thoroughly with water to remove all chemical residue

and left to dry completely before reuse.

Reinsert foam section into the cover. Please note, for the Spex Backrest, the contouring inner foam section

has to go back in the correct way. Ensure the at surface is facing towards the user, and the cube section is

facing the shell. Once the foam is secured inside the cover, zip cover closed.

Maintenance & Cleaning

Cleaning the rigid shell

Shell may be wiped clean with mild detergent and water. Rinse with clean

water. Dry thoroughly after rinsing.

Cleaning positioning components

Positioning components can be wiped clean with mild detergent and water. Spex recommends using AHP

(Accelerated Hydrogen Peroxide) disinfectant wipes. Wipe away any chemical residue with clean water and

dry thoroughly after wiping.

Do not immerse positioning components in water.

Inner foam

The Back Support inner foam is not designed to get wet in any way, as this will greatly reduce its life. If

soiled, Spex recommends replacing the inner foam. If foam accidentally becomes wet, dry thoroughly

before replacing inside the cover.

Spex recommends the purchase and use of an incontinence cover (which protects the inner foam and can

be washed and sanitized).

SPEX BACK SUPPORT USER MANUAL 11 WWW.SPEXSEATING.COM

Disposal & Recycling

Your Spex Seating System is manufactured using a variety of materials, most of which can be recycled.

Once it reaches the end of its life, if you are the legal owner, do not dispose of as ordinary household

waste but take your Spex System to an approved recycling or collection point, to dispose of according

to local laws and regulations.

Separate collection and recycling of the Spex System when disposing ensures protection of the environ-

ment and assists with natural resource conservation.

Environment

Moisture: Keep your Back Support dry at all times, as contact with water or excess moisture could cause

corrosion, degradation to the functionality of your Back Support, or potential failure. If your Back Support

becomes damp or wet, thoroughly wipe with a dry cloth as soon as possible. Do not use your Back Sup-

port in a showering or pool facility.

Temperature: Your Back Support may not function as intended when used at extreme temperatures.

Keep the Back Support away from sources of extreme heat or extreme cold to avoid burns from the metal

components.

Dirt: Small particles such as dust, dirt and sand may restrict optimum functionality. Regularly check your

Back Support to ensure no build-up occurs around openings and moving parts.

Following installation and adjustment, the back can be easily removed from the wheelchair when

necessary. To remove, pull quick release latch upwards to unlock.

Once both latches are released, tilt forward and pull upwards.

Removing the Back Support

Proper re-attachment after removal

To re-attach the Back Support to the hardware receivers, line up the lower pins into the hook mounts and

push down into place. Once properly inserted, lock the pins into place.

Reconnecting the Back Support

Ensure that the quick release latches are securely locked into position. To double-check, try the

Back Support to ensure it is locked.

WARNING

SPEX BACK SUPPORT USER MANUAL 12 WWW.SPEXSEATING.COM

The Spex Back Support has been designed to accommodate postural asymmetries and adapt to dierent

Contouring the Back Support Surface

(Spex and SuperShape Backs Only)

WARNING

Ensure the user has the hip belt fastened.

Lean the user forward to remove the inner contouring section of the Back

Support (the cover will remain secured to the Back Support shell) and replace

with pillow.

Lean the user back.

The second person must remain with the wheelchair user to

support them and keep them safe from falling.

Now the contouring section can be changed to suit the user’s posture. Once

nished, remove the pillow and re-insert the inner contouring section.

The Spex Back Support has been designed to accommodate postural asymmetries

and adapt to dierent morphologies. This guide shows how the inner section of

the Spex Back Support can be changed. Postural needs can change over time,

that’s why the Spex system can be changed on-the-spot. Once the user has nished

using the Spex Back Support, it can be refurbished and issued to another user. See

re-issuing to another User section in this user manual (page 12).

Each cube compartment contains 2 cubes. These may be removed or added to as

required. Each compartment can have up to 5 layers of cubes. Keep any unused

cubes as these can be used at a later date if the client’s needs change or if the

Back Support is re-issued for use with another client. The cubes must always face

the rear of the Back Support. This allows for the full molding & pressure-relieving

properties of the Back Support to be eective.

Back/spinal protrusions

Undo the zipper on the Back Support to release the inner contouring inner

section. Remove this from the cover. You can now remove layers of contouring

cubes from where back protrusions need to recess into the Back Support. There is

sucient padding behind the user if all of the compartment’s cubes are removed

to accommodate a prominence.

Back/spinal indentations

Undo the zipper on the Back Support to release the inner contouring inner section.

Remove this from the cover. You can now add layers of contouring cubes where

back indentations need more contouring support.

How to make changes with the user sitting in the wheelchair

Two people are required for this adjustment. Before doing this adjustment, retrieve

a soft head pillow or similar padded objects.

SPEX BACK SUPPORT USER MANUAL 14 WWW.SPEXSEATING.COM

Spex is the manufacturer of Spex wheelchair seating which installs to most wheelchair

bases/chassis. Spex is not responsible in any way or form for the choice of wheelchair base

or chassis that is selected for the user and to which Spex Seating is installed.

Normal manufacturer’s guidelines must be followed and adhered to. Failure to follow these

measures can put the user or caregiver at risk of harm, injury or even death. Wheelchair

users who may be unaware of their body position, unable to maintain a safe body position

and/or who are non-verbal have the highest risk of injury and caregivers should be more

cautious with these users. A second caregiver should be responsible to ensure the safety

of these users.

Wheelchair users experience many situations that aect wheelchair stability, tipping and

associated performance. Examples of such situations include ramps, slopes, steps, curbs,

soft ground, accessories such as an oxygen cylinder, seating systems and wheelchair

modications. Such situations, coupled with user characteristics (body shape and size)

and abilities can often lead to accidents and poor product performance. Spex is not

responsible for any operation of the wheelchair base/chassis whether through intended or

inappropriate use and/or any injury or harm caused to the user by the wheelchair.

The improper use of the wheelchair chassis and Spex Seating can be dangerous to the user

or caregiver through:

• Inappropriate operation of the wheelchair chassis and seating functions.

• Inappropriate movement of the wheelchair.

• Inappropriate use of the wheelchair by a patient who has not been assessed by a

certied therapist/clinician responsible for their seating.

• Leaving the user unattended in the wheelchair near other potentially unsafe objects

or in harm’s way.

• Leaving a potentially agitated user in an unsupervised area.

• Leaving a patient in a wheelchair on a sloping surface.

• Leaving a wheelchair unattended on a sloping surface.

• Transferring a patient in or out of the wheelchair without setting wheel locks.

• Using non-Spex accessories on the Spex wheelchair seating.

• Using the Spex Seating at temperatures below 0° Celsius (32° Fahrenheit)

and maintenance instructions within this manual as well as the following transit instructions. If feasible,

the wheelchair user should transfer to the vehicle seat and use the vehicle-installed occupant restraint

systems.

Spex Seating System has been designed to accommodate the proper use of vehicle-anchored belt restraints.

Spex achieved a rating of Excellent (16 out of 16), for ease of properly positioning a belt restraint, and the

degree to which proper belt restraint can be achieved, based on the methods of Annex D. The following

items of the Spex Seating System have been tested and are suitable for use in a motor vehicle:

• Full Height Back Support Models

• Seat Base

• Cushion Models

• Arm and Thigh Supports

• Trunk Lateral Supports

• Head Supports

Note: Back supports that are lower than the user’s shoulder height are not certied and not recommended

for transport in a vehicle. Eg. Vigour Lo and Vigour Mid back supports.

Assembly, Use, Maintenance & Limitations

• Adjustments to the set-up of the wheelchair must only be carried out by a qualied therapist,

professional, or seating technician. Custom contoured/bespoke systems may require a qualied

professional to congure and install the seating system.

• After carrying out any adjustments ensure all bolts, screws and nuts are securely fastened again to

ensure safety when travelling in a vehicle.

• Ensure the top and bottom mounts of the backrest and the front and rear mounts of the seat pan

are installed as far apart from each other as possible to give a stronger 4-point attachment to the

wheelchair frame. Ensure the quick release latches are engaged.

• Do not use the Spex Seating System as a vehicle seat if seating components which have not been

successfully crash tested are used anywhere on the seating system. Spex Seating is designed and

certied using only Spex components. Spex is not liable in the event where other manufactured

seating systems are used in conjunction with Spex Seating.

• At regular intervals check that all the fastenings on the Spex Seating System have not become loose

during day to day use and re-tighten if necessary.

• Ensure the swing-away laterals are in their locked position before using the seat as a vehicle seat in a

motor vehicle.

Correct Positioning of Belt Restraints

When using the Spex Seating System as a vehicle seat, both a pelvic-

belt restraint and shoulder-belt restraint must always be used. To

correctly position the belt restraints on the wheelchair occupant, the

following must be ensured:

• The pelvic-belt restraint should be worn low across the front of

the pelvis near the junctions of the pelvis and thighs.

• The angle of the pelvic-belt restraint should be between 30° to

75° relative to the horizontal and, ideally, between 45° to 75° to

the horizontal (as shown in Figure 2).

• The belt-restraint buckle of three-point belt restraints should

be placed in contact with the occupant’s body and away from

wheelchair components.

• The junction of the shoulder-belt and pelvic-belt of three-point-

belt restraints should be located near the hip opposite the

shoulder over which the diagonal belt crosses and not near the

midline of the occupant.

• Belt restraints should not be routed outside of the wheelchair

wheels or over the wheelchair armrests, and should not be held

away from the body by wheelchair components or parts.

• Upper torso belt restraints should t directly over, and in contact

with, the middle of the shoulder.

• Belt restraints should be adjusted to t as snugly as possible,

consistent with user comfort.

• Belt restraints should not be worn twisted in a manner that reduces

the area of contact of the belt webbing with the occupant.

seat in a motor vehicle, dynamically tested to the performance

requirements of ISO 7176-19 and installed, used and maintained

according to the manufacturer’s instructions.

5. The Spex Seating System must only be used as indicated in this

user manual.

6. Both pelvic and shoulder-belt restraints as a part of a complete

Wheelchair Tie down and Occupant Restraint System (WTORS)

which meets ISO 10542-1 shall be used to achieve eective

occupant restraint and optimum protection in a vehicle impact; the

contact with the wheelchair occupant’s shoulder and chest.

The Spex Seating System must only be used for forward-facing

seating in motor vehicles.

In order to reduce the potential of injury to vehicle occupants,

wheelchair-mounted rigid trays not specically intended for use

during travel in motor vehicles must be:

a. Removed and secured separately in the vehicle or

b. Secured to the wheelchair so they will not break free in a crash

and

• Be positioned with a gap of at least 3” (75 mm) between

the back edge of the tray and the wheelchair occupant’s

abdomen and/or chest so as not to interfere with the proper

belt-restraint use, and

• Have energy absorbing padding placed between the back

edge of the tray and the wheelchair occupant.

Alterations or substitutions must not be made to the seating

system structure, parts or components, without rst consulting

Spex.

The use of a postural pelvic belt attached to the wheelchair

base or seat frame is encouraged during travel, but these belts

should be positioned so that they don’t interfere with the proper

positioning of crashworthy belt restraints, and they should not be

relied on for occupant protection in crash situations unless the

postural belt has been designed to comply with, and perform to

the requirements of WC19.

Postural support devices that are not labelled as conforming to

ISO 16840-4 may be used when in a vehicle, but should not be

relied on for occupant restraint.
