2.0 SAFETY INFORMATION
2.1 TRANSPORTATION WARNINGS!
WARNING! Risk of Death, Serious Injury or Damage · Risk of severe injury when transporting the client within a wheelchair fitted with an Invacare® Matrx® E2 Back in a motor vehicle.
TRANSPORTING THE CLIENT IN A MOTOR VEHICLE WITHIN A WHEELCHAIR FITTED WITH A MATRX BACK
The following guidelines should be made available to all parties responsible for the transportation of the client, such as schools and transport providers. · Wherever practicable Motion Concepts recommends that the client is transferred out of the wheelchair into a vehicle seat using a lap and diagonal seat belt or an appropriate child safety seat. · The following back supports have been dynamically tested and meet the requirements of ISO 16840-4:2009, Wheelchair Seating- Part 4: Seating Systems for Use in Motor Vehicles; and Section 20, ANSI/RESNA WC-4:2017, Wheelchair Seating Systems for Use in Motor Vehicles:
Invacare® Matrx® E2S Back with Removable Hardware and Elan Headrest Invacare® Matrx® E2S Back with Fixed Hardware and Elan Headrest A forward facing frontal impact test was performed for each configuration using an ISO/RESNA Surrogate Wheelchair Frame (SWCF) and a Hybrid III Midsize-Adult Male Anthropomorphic Test Device (ATD). The SWCF was secured by a four-point, strap type wheelchair tie-down and the ATD was restrained by a surrogate threepoint belt with a SWCF-Anchored Lap Belt. · Invacare® Matrx® E2 Backs used to transport a client should be equipped with a Headrest Support (i.e. restricted to back heights 14in (36cm) and higher); and may only be used in conjunction with wheelchairs that comply with the performance requirements of RESNA WC19 or ISO 717619. · For safe transportation of a client within a wheelchair in a motor vehicle, refer to the user manuals of the wheelchair and tie-down and occupant restraint system (WTORS)- see additional information below.
BEFORE ENTERING THE VEHICLE CHECK THE FOLLOWING:
The 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. A Head Support should be securely fitted and correctly adjusted close to the rear of the client’s head during transportation, to reduce the risk of whiplash injuries.
WHEELCHAIR TIE-DOWN & 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
– 4 –

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).
IMPORTANT! If the wheelchair and Invacare® Matrx® E2 Back is transported unoccupied, the wheelchair should be tied down with suitable equipment according to the manufacturer’s instructions. If the equipment is dismantled for transportation, ensure that all parts are secured safely within the vehicle.
2.2 GENERAL SAFETY AND INSTALLATION WARNINGS!
WARNING! Risk of Death, Serious Injury, or Damage Lighted cigarettes dropped onto an upholstered seating system can cause a fire resulting in death, serious injury or damage. Wheelchair occupants are at particular risk of death or serious injury from these fires and resulting fumes because they may not have the ability to move away from the wheelchair. ·DO NOT smoke while using this wheelchair
WARNING! Risk of Serious Injury When establishing the mounting position for the Invacare® Matrx® back, ensure the stability of the wheelchair is not compromised. Adjusting the forward and aft position and/or angle of the backrest will alter the user’s center of gravity within the wheelchair. It may be necessary to reposition the front casters, rear wheels, back angle, tilt-in-space, recline position and/or seat depth before use.
WARNING! Risk of Serious Injury or Damage · The procedures in this manual should be performed by a qualified technician · The hardware provided is high strength and tested for durability. Do Not substitute hardware. Use only the original hardware supplied with your Matrx back · Attaching hardware that is loosely secured could cause loss of stability resulting in serious injury or damage. · After ANY adjustments, repair or service and before use, make sure that all attaching hardware is tightened securely. · DO NOT install the Invacare® Matrx® back assembly onto back canes with an outside diameter greater than 1″ (25mm) or less than 3/4″ (19mm). Otherwise, injury or damage may occur. · For power seating applications, the Fixed Mounting Hardware must be used.
WARNING! Risk of Injury Invacare® Matrx® products are specifically designed and manufactured for use in conjunction with Invacare® Matrx® accessories. Accessories designed by other manufacturers have not been tested by Motion Concepts and are not recommended.
WARNING Risk of Injury Skin condition should be checked very frequently after the installation of any new seating system. Working with you therapist, physician and service provider is the best way to assure that a seating choice meets your individual needs.

IMPORTANT! Unless otherwise necessary, always ensure that adjustments are made symmetrically on the left and right mounting brackets.
IMPORTANT! The MiniSet and EasySet mounting brackets allow for installation of the E2S/E2D Back onto back canes up to 2″ (51mm) wider or 1″ (25mm) narrower than the nominal back width.
! PLEASE NOTE
The E2 Mounting Brackets will simultaneously adjust the Width and Height of the back (relative to the back canes). Please read through ALL set-up/adjustment instructions, PRIOR to beginning the E2 Back installation.
3.5.1 MOUNTING BRACKET SET-UP/ PRELIMINARY BACK INSTALLATION:
NOTE: The Preliminary Set-up should be performed without the user seated in the chair Mounting Bracket Set-Up: (see Fig. 5a/5b) 1. Loosen the adjustment screws (A) and adjust both mounting brackets (B) horizontally (1) so that the mounting pins (C) will align with the mounting plates (D) on the wheelchair back canes. Preliminary Installation: (see Fig. 6) 2. Install the E2S/E2D back onto the mounting plates (2). (note: the preliminary installation steps are identical for the MiniSet and EasySet hardware). · Align/install the lower mounting pins (C2) into the hooked slots at the

Back Height and Width Adjustment: (see Fig. 7, Fig. 8) 1. With the E2 Back locked into place, and the end user seated in the chair (if
possible), carefully adjust the back shell along the vertical adjustment slot (A) (1) until the desired back height is achieved. NOTE: the minimum recommended back height* is 4″- 5″ (10-13cm) from the top of the seat surface.
2. While maintaining the desired back height, adjust each mounting bracket (B) horizontally (2) so that a minimum gap of 1/8-1/4″ (3-6mm) exists between the heads of the mounting pins (C) and the mounting plate (D). NOTE: Unless otherwise necessary, the E2 back should be centered between the back canes during installation.
3. Once all height and width adjustments are finalized, fully tighten/secure both mounting brackets into position.
4. Proceed to section 3.5.3 for Back Angle and Depth Adjustment

*Note: The minimum recommended back height is provided as a guideline only. The final back height should be adjusted/set to best meet the end user’s needssee Important! note below.

IMPORTANT! Always ensure that the bottom of the back is positioned anatomically below the Posterior Superior Iliac Spine (PSIS). If you have any questions or concerns regarding proper back height adjustment, please contact your Motion Concepts representative for assistance.
