a skin management program.
Your therapist and physician should be consulted if you have questions regarding individual limitations

2 Safety
2.1 Transporting the Client Within a Wheelchair Fitted with a Matrx Back in a
Motor Vehicle
The following guidelines should be made available to all parties who are responsible for the transportation
of the client, such as schools and transport providers.
Wherever practicable the client should be transferred out of the wheelchair into a vehicle seat and use
a lap and diagonal seat belt or an appropriate child safety seat.
The Matrx back has been dynamically tested and meets the requirements of ISO 16840-4 and Section 20,
ANSI/RESNA WC/Volume 4 “Wheelchair Seating Systems for Use in Motor Vehicles”. A Surrogate
Wheelchair Base (SWCB) and a Hybrid III Midsize-Adult Male Anthropomorphic Test Device were used
in a forward facing frontal impact test. The SWCB was secured by a four-point, strap type wheelchair tiedown and the occupant restraint was a vehicle anchored lap and diagonal occupant restraint system.
Matrx backs should only be used in conjunction with wheelchairs that comply with the performance
requirements of ANSI WC19 or ISO 7176-19.
Before Entering the Vehicle Check the Following:
Matrx Back - must be securely fastened into the wheelchair as described in the user manual.
Posture Belts & Harnesses - should remain fitted during transportation, although they are designed to
provide postural support only, they are not intended for safety during transportation.
Head Support - must be securely fitted and correctly adjusted close to the rear of the client’s head during
transportation, in order to reduce the risk of whiplash injuries.
The Wheelchair Tie-down and Occupant Restraint System (WTORS)
Wheelchair Tie-down - The wheelchair must be securely tied down within the vehicle, in a forward facing
position, in accordance with the wheelchair and tiedown manufacturers instructions.
Occupant Restraint - A suitable occupant restraint system must also be fitted in accordance with the
manufacturer’s instructions. A minimum is a lap and diagonal belt (lap belts on their own are not suitable).
Restraints that loop over the shoulder and anchor to the vehicle floor should be avoided where possible,
as they can cause a heavy downward load through the client during an impact, the preferred type anchor
above and behind the shoulder as with a car seat belt. The lap section of the belt should fit snugly over
the pelvis of the client and should not be able to ride up to the abdominal area. The upper torso section
of belt should be in contact with the client’s chest and fit over the shoulder(s), while not cutting into the
neck or slipping off the shoulder(s).
2.2 Intended Use
The Matrx PB is contoured to provide midline support and positioning. The extended range of sizes provides
exceptional support and comfort for a wide range of user needs.
Check ALL parts for shipping damage. If shipping damage is noted, DO NOT use. Contact
carrier/dealer for further instruction.
If the wheelchair and Matrx back are to be transported unoccupied, the wheelchair should be
tied down with suitable equipment according to the manufacturer’s instructions. If the
equipment is to be dismantled for transportation, ensure that all parts are secured safely
within the vehicle.

2.3 General Warnings
WARNING
DO NOT USE THIS PRODUCT OR ANY AVAILABLE OPTIONAL EQUIPMENT WITHOUT
FIRST COMPLETELY READING AND UNDERSTANDING THESE INSTRUCTIONS AND
ANY ADDITIONAL INSTRUCTIONAL MATERIAL SUCH AS OWNER’S MANUALS, SERVICE
MANUALS OR INSTRUCTION SHEETS SUPPLIED WITH THIS PRODUCT OR OPTIONAL
EQUIPMENT. IF YOU ARE UNABLE TO UNDERSTAND THE WARNINGS, CAUTIONS OR
INSTRUCTIONS, CONTACT A HEALTHCARE PROFESSIONAL, DEALER OR TECHNICAL
PERSONNEL BEFORE ATTEMPTING TO USE THIS EQUIPMENT - OTHERWISE, INJURY OR
DAMAGE MAY OCCUR.
ACCESSORIES WARNING
Invacare products are specifically designed and manufactured for use in conjunction with Invacare
accessories. Accessories designed by other manufacturers have not been tested by Invacare and
are not recommended for use with Invacare products.
INSTALLATION WARNING
After any adjustments, repair or service and before use, make sure that all attaching component
parts are secure.
DO NOT install the Matrx PB assembly onto back canes with an outside diameter greater than 1inch or less than 3/4-inch. Otherwise, injury or damage may occur.
The mounting position of the Matrx PB is directly related to the chair's stability. When the Matrx
PB is added to a TILT and/or RECLINING chair, it may cause a decrease in the chair's stability. It
may be necessary to reposition the FRONT CASTERS, REAR WHEELS, BACK ANGLE, TILT-INSPACE, RECLINE POSITION and/or SEAT DEPTH before use. Use extreme caution when using
a new seating position.
When the Matrx PB is added to a TILT and/or RECLINING wheelchair, a RIGIDIZER BAR or
CROSSBAR must be present to stabilize the back canes.
Ensure the Matrx PB is properly secured to the wheelchair before using. Otherwise injury or
damage may occur.
WARNING
Skin condition should be checked very frequently after the installation of any new seating system.
Your therapist and physician should be consulted if you have any questions regarding individual
limitations and needs.
Working with your therapist, physician, and equipment supplier is the best way to assure that a
seating choice matches your individual needs.
As the needs of the individual become more complex, the seating evaluation becomes more
important.
