Installing a back support on a wheelchair may effect the
center of gravity of the wheelchair, and may cause the
wheelchair to tip backwards potentially resulting in
injury to the user.
B. ANTI-TIPS
Anti-tip tubes can help keep your chair from tipping over
backward in normal conditions.
1. Sunrise recommends the use of anti-tip tubes.
2. ALWAYS assess the need for anti-tips or an
amputee axle adapter brackets that could be
added to the wheelchair to help increase the
stability of the wheelchair and seating system.
If you fail to heed these warnings, damage to your chair,
a fall, tip-over, or loss of control may occur and cause
severe injury to the rider or others.
C. PUSHING OR LIFTING
Do not use the J3 Plus Back to move or push the wheelchair.
WARNING
If you fail to heed these warnings, damage to your chair, a
fall, tip-over, or loss of control may occur and cause
severe injury to the rider or others.
D. COMPATIBILITY
The J3 Plus Back is designed to be compatible with most
wheelchairs with the following exception:
1. Wheelchairs that are angle adjustable with
recline or tilt, and result in a back angle
greater than 60 from the vertical.
The J3 Plus Back has been dynamically tested for use
in a motor vehicle. This system conforms with
ANSI/RESNA WC-20. If the J3 Plus Back is to be used in
a transit situation, it must be mounted to a wheelchair
that conforms to the performance requirements of ANSI/
RESNA WC-19. For rider safety, please follow all
installation, use, and maintenance instructions within this
manual as well as the transit instructions below.
1. If possible and feasible, the rider should transfer to
the Original Equipment Manufacturer vehicle seat
and use the vehicle restraints.
2. The distance between the top of the user's
shoulder and the top of the back should not exceed
6.5" (16.5 cm).
3. The wheelchair must be labeled as appropriate for
use as a seat in a motor vehicle, dynamically tested
to the performance requirements of ISO Standard
7176-19 and installed, used, and maintained
according to the manufacturer's instructions.
4. If the original wheelchair seat was replaced, the
new seat must be approved for wheelchair transit,
