! PLEASE NOTE
When establishing the mounting position for
the Prism mounting Hardware, please insure
the stability of the wheelchair is not
compromised.
Adjusting the forward and aft position of the
backrest will alter the user‘s center of gravity within
the wheelchair. A recessed back position can
significantly reduce the rearward stability of the
wheelchair. Similarly, a more forward back position
will reduce the wheelchair’s forward stability.
The Back Mounting Plates and the Cane Clamps are shipped pre-assembled
with the hardware oriented in the forward most back position (see Fig. 1
below). By altering the orientation of the Cane Clamps with the Back
mounting Plates, the hardware can be positioned to provide a rear most
mounting position for the back if desired (see Fig. 2 below).
To make the adjustment from the forward most to the rearmost position
(or vice versa), detach the Back Mounting Plates from each Cane Clamp by
removing the 3 Depth/Recline Adjustment Screws. Then turn the Cane
Clamp 180° and re-attach it to the Mounting Plate in its original orientation.
The Prism Hardware offers users a full 5” range of forward and rear
adjustability (Angle adjustment forward 15°, back 20°).
Each mounting plate provides an individual adjustment range of 1.5”.
