CHAPTER 7:
Velcro -Style Adjustable Back Upholstery
®
Note: When adjusting the tension of the back upholstery, DO NOT apply so much tension that the backrest tubes 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 7-1.
2. Completely detach the two backrest ears from the padded back, but do not remove them from the backrest.
3. Adjust to the desired tautness. The closer together the two backrest ears, the more taut the padded back will be.
The farther apart the two backrest ears, the looser the padded back 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 padded back with the two backrest ears to ensure that the top of the back upholstery is even
with the top of the backrest.
5. If desired adjust the tension of the strap(s).
6. Securely attach the padded back to the backrest ears using the Velcro
back into position in front of the rigidizer bar.

Replacing

1. Lift the back flap to expose the backrest ears. See Figure 7-2.
2. Completely detach the two backrest ears and strap(s) from the padded back and remove them from the backrest.
Note: If your chair has Integrated or Fold-Down Push Handles, you will need to remove the bolts that secure the
backrest ears to the backrest (using a 1/8" Allen wrench) and the bolts that secure the backrest posts inside the
backrest (using a 5/32" Allen wrench). See Figure 7-3 and see "Adjusting the Backrest Height" on page 4-3.
3. Remove the seat cushion.
4. Detach the bottom flap from the seat upholstery.
5. Attach bottom flap of the new back upholstery to seat upholstery.
6. Install the two new backrest ears on the backrest.
7. Adjust to the desired tautness. See "Adjusting the Tension" on page 7-1.
8. Align the top of the padded back with the two backrest ears to ensure that the top of the back upholstery is even
with the top of the backrest.
9. Reinstall the strap(s) and adjust to the desired tautness.
10. Securely attach the padded back to the backrest ears and lower the back flap back into position in front of the
rigidizer bar.
11. Replace the seat cushion.
