Invacare Matrx ELITE E2S Back / E2D Back, Matrx Series Manual

MATRX ELITE E2S/E2D BACK INSTALLATION

FITTING THE E2S/E2D BACK TO THE WHEELCHAIR

PRIOR to installation, verify the diameter of the wheelchair back canes (A) and the width between back canes (B)

*wwhh = width/height

Hardware fits the following back cane diameters:

• 1" (25mm)
• 7/8" (22mm)*
• 3/4" (19mm)*

*requires cane inserts (provided)

The type of Mounting Hardware can vary depending on several factors, including the height of the back shell, the needs of the end user and the type of wheelchair.

* Note: E2S/E2D Backs may be configured with EasySet hardware for the back heights indicated. (The range of back height adjustment will be limited for these configurations)

E2 FIXED HARDWARE ASSEMBLY OVERVIEW

The E2 Fixed hardware utilizes a unique fixed mounting plate* in place of the (seahorse) mounting plate and mounting bracket ass'y used on the E2 Removable Hardware. If converting from removable to fixed hardware, the cane clamps from the E2 Removable Hardware assembly are reused to complete the E2 Fixed Hardware installation.

* Note: There are two styles of fixed mounting plates for use on the E2S/E2D Back (depending on the overall height of the back shell). Back heights of 16" (41cm) or less come standard with Fixed MiniSet hardware; and back heights of 18" (46cm) and greater come standard with Fixed EasySet hardware

E2 FIXED MOUNTING PLATE INSTALLATION

Unless otherwise necessary, always ensure that adjustments are made symmetrically on the left and right mounting brackets.

The Fixed MiniSet mounting plates allow for installation of the E2S/E2D back onto back canes up to 1" (25mm) wider or 1" (25mm) narrower than the nominal back width. The Fixed EasySet mounting plates allows for installation of the E2 Back onto back canes up to 2" (51mm) wider or 1" (25mm) narrower than the nominal back width.

INSTALLING THE E2 FIXED MOUNTING PLATES

NOTE: Prior to installing the Fixed Mounting Brackets, the E2 Back Cover must first be removed by releasing the hook and loop fasteners along the bottom edge and inside of the back shell.

Fixed Mounting Plate Installation: (see Fig. 1 and Fig. 2)

1. Working on one side of the back shell at a time, align the washer plate (B) with the slots in the fixed mounting plate (A) and insert the adjustment screws (C) through both parts.
   
   Fig. 1. MiniSet Fixed Mounting Plate Installation
   
2. From the rear of the back shell, align the mounting plate assembly (from step 1 above) with the vertical slot in the E2 back shell, then secure* the adjustment screws into the threaded nut plate (on the inside of the back shell).
3. Repeat steps 1. and 2. to install the fixed mounting bracket onto the opposite side of the back shell.
   
   Fig. 2. EasySet Fixed Mounting Plate Installation

(*note: the fixed mounting plates can remain loosely installed at this time. The mounting plate assemblies will be fully secured following final installation/adjustment of the E2S/E2D Back- refer to "E2 BACK INSTALLATION, SET-UP & ADJUSTMENT" section)

CANE CLAMP ORIENTATION

The orientation of the Cane Clamps (A) provides approximately 4" (102mm) of fore/aft adjustment for the Fixed EasySet hardware, and 3" (76mm) of fore/aft adjustment for the Fixed MiniSet hardware. PRIOR to installing the Cane Clamps, determine the orientation that will best meet the needs of the end user.

• Standard Orientation (Fig. 3a/4a) = maximized seat depth
  
  
• Inverted Orientation (Fig. 3b/4b) = minimized seat depth
  
  
  (*Requires the mounting plate to be disassembled from the cane clamp and rotated 180°)

NOTE: Additional depth adjustments can be made via the slotted channels in the fixed mounting plates - see "BACK DEPTH AND ANGLE ADJUSTMENT" section.

CANE CLAMP INSTALLATION

(see Fig. 5a/5b; Fig 6a/6b)

NOTE: The mounting position of the cane clamps should be estimated so that, when installed, the installed Elite E2S/E2D back will be close to the desired back height. A higher cane clamp mounting position typically works best. Additional fine-tune height adjustment of the back shell will be available following installation

1. (If applicable) Remove existing wheelchair back according to the wheelchair manufacturers instructions.
2. Install the MiniSet
   
   
   or EasySet
   
   
   Cane Clamps onto each back cane as follows:
   • (If necessary) Install the appropriate cane insert onto the back cane (1).
   • Position/close the outer clamp (A) over the back cane (cane insert) and align it with the inner clamp (B).
   • Loosely secure the clamp assembly to the back cane via the mounting screw(s) (2).
   • Adjust the height* of each clamp assembly (3) equally along the back canes in order to achieve the estimated final back height.
   • Fully secure all cane clamp mounting screws (2)

*NOTE: The final back height can be further adjusted (via mounting brackets) following installation of the Elite E2S/E2D back- see "BACK INSTALLATION, WIDTH AND HEIGHT ADJUSTMENT" section.

E2 BACK INSTALLATION, SET-UP & ADJUSTMENT

NOTE: During final set-up, we recommend having the end user seated in the wheelchair to best fit/position the Elite E2S/E2D back.

Unless otherwise necessary, always ensure that adjustments are made symmetrically on the left and right mounting brackets.

PLEASE NOTE
The E2 Fixed Mounting Plate screws (A) 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 back installation

The vertical (height) adjustment slots on each E2S/E2D back shell will vary in length depending on the nominal back height- refer to Table 1.

Table 1. BACK SHELL: RANGE OF HEIGHT ADJUSTMENT:

BACK INSTALLATION, WIDTH AND HEIGHT ADJUSTMENT

Installation, Width and Height Adjustment: (see Fig. 7a/7b, 8a/8b)

1. Loosen (do not remove) the adjustment screws (A), then adjust the width of both mounting plates (B) horizontally (1) so that the mounting plates align with the left and right cane clamp assemblies- see Fig 7a/8a.
   
   Fig. 7a E2 Back Installation - Fixed MiniSet
   
   Fig. 8a Back Installation - Fixed EasySet
   
2. To install the Elite E2 Back (2), insert the mounting screws (C) through the cane clamp (E) and mounting plate (B), and secure into the threaded nut plate (D).
3. With the E2 Back securely installed, set the final back height* and adjust the back shell so that it is centered (symmetrically) between the back canes (3). When possible, this step should be performed with the user seated in the chair in order to best set the back position.
   NOTE: use the hash marks along the vertical slots on the back shell to ensure both back height (mounting brackets) are adjusted equally. The minimum recommended back height* is 4"- 5" (10-13cm) from the top of the seat surface - see Fig 7b/8b.
   
   
4. Tighten the adjustment screws (A) on both mounting plates (B) to secure the Elite E2S/E2D Back in the desire position.
5. Refer to "BACK DEPTH AND ANGLE ADJUSTMENT" Section for E2 Back Depth and Angle Adjustments.

* 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 needs- see Important! note below.

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.

BACK DEPTH AND ANGLE ADJUSTMENT

PLEASE NOTE
The Mounting Screws (C) on the cane clamp assembly will simultaneously adjust the Depth and Angle of the E2 Back (relative to the back canes). Please read through ALL adjustment instructions, PRIOR to beginning the adjustments

1. With the end user seated in the chair (when possible), loosen(do not remove) the mounting screws (C) on the left and right cane clamp assemblies, then adjust the E2 back depth (Fig. 9a/10a) (4) and back angle (Fig. 9b/10b) (5), as necessary, to best fit the needs of the end user*.
   
   Back Depth and Angle Adjustment - Fixed MiniSet
   
   Back Depth and Angle Adjustment - Fixed EasySet
   
2. Once the final back depth and angle has been determined, fully tighten the mounting screws (C) on both cane clamps (E) to secure the Elite E2S/E2D Back into place, and verify ALL mounting/adjustment hardware is fully secured.
   *note: the slotted channels in the fixed mounting plates allow for approximately 1" (26mm) of depth adjustment on the Fixed MiniSet hardware, and up to 1.5" (39mm) of depth adjustment on the Fixed EasySet hardware. Both fixed hardware assemblies allow for approximately ±20° of angle adjustment.

NOTE: The range of depth adjustment will be reduced when the angle of the Elite E2S/E2D back (fixed mounting plate) is altered.
