FITTING THE BACK TO THE CHAIR
DETERMINING COMPATIBILITY
Wheelchair Types
The J3 Carbon Back is designed to be compatible with
most wheelchairs with the following exceptions:
Wheelchairs that are angularly adjustable, recline or tilt
and result in a back angle greater than 60 degrees from
the vertical should not be used.
WARNING!
Use with these types of wheelchairs may cause the back
to accidentally disconnect from the wheelchair resulting in
a fall and the potential for serious injury.
Wheelchair Dimensions
The J3 Carbon Back is designed to replace the
wheelchair’s sling upholstery. Prior to installation determine
if the wheelchair used has compatible back canes, by
measuring the width between your back canes as seen in
Figure 1. Then using that measurement, check Table 1,
(Fixed Mount) or
Table 2, (Quick Release), to determine if the back will fit
your chair.
Next check that the back canes are a compatible diameter.
The J3 Carbon Back hardware can be mounted on
wheelchair back canes that measure in diameter 3/4”
(19mm)(with insert), 7/8” (22mm)(with insert) or 1” (25mm)
(no insert).
If you cannot determine that the back canes are
compatible please contact your authorized Sunrise Medical
provider or Sunrise Medical customer service.
