Replacing Velcro Adjustable Back Upholstery
Velcro Adjustable Back
Upholstery
(TR Series, YG Series, YR Series, ZR Series, Aero Z
and Evo)
Note: When adjusting the tension of the back
upholstery, DO NOT apply so much tension that the
back canes are pulled out of vertical. If this occurs, you
may cause the chair to “track” improperly or to develop
a “floater.”
Adjusting the Tension
1. Lift the back flap to expose the backrest ears. See
Figure 54.
2. Completely detach the two backrest ears from the
back upholstery, but do not remove them from the
back canes.
3. Adjust to the desired tautness. The closer together
the two backrest ears, the tauter the back upholstery
will be. The farther apart the two backrest ears, the
looser the back upholstery will be. Tighter back
upholstery will increase the stability and maintain
normal maneuverability of the chair because the
user is pushed forward slightly. Looser back
upholstery will increase maneuverability, but will
make the chair more prone to tip over backward
because additional weight is being distributed
behind the rear wheels.
4. Align the top of the back upholstery with the two
backrest ears to ensure that the top of the back
upholstery is even with the top of the back canes.
5. Securely velcro the back upholstery to the backrest
ears and lower the back flap back into position in
front of the rigidizer bar.
Replacing the Upholstery
1. Lift the back flap to expose the backrest ears. See
Figure 55.
2. Completely detach the two backrest ears from the
back upholstery and remove them from the back
canes.
3. Remove the seat cushion.
4. Detach the back upholstery from the seat upholstery
by separating the Velcro at the underside of the seat
upholstery. Note: On YG Series chairs, the backrest
upholstery attaches to the top of the seat upholstery.
5. Attach new back upholstery to seat upholstery at the
underside of the seat upholstery. Note: On YG
Series chairs, the backrest upholstery attaches to
the top of the seat upholstery.
6. Install the two backrest ears on the back canes.
7. Adjust to the desired tautness. See “Adjusting the
Tension” on page 49.
8. Align the top of the back upholstery with the two
backrest ears to ensure that the top of the back
