General Product Safety
Safe application of this product depends upon your good judgment and common sense,
as well as that of your provider, caregiver, and/or healthcare professional, and your
attentiveness in following the cautions, notes, and instructions in this manual.
NOTE: We have compiled this manual from the latest specifications and product
information available at the time of publication. We reserve the right to make changes
as they become necessary. Any changes to our products may cause slight variations
between the illustrations and explanations in this manual and the product you have
purchased.
Y WARNING: All Ride Designs support surfaces are designed to help reduce the
incidence of pressure sores. However, no back support can completely eliminate sitting
pressure or prevent pressure sores. The Ride Corbac is not a substitute for good skin care
including proper diet, cleanliness, and regular pressure relief techniques.
CAUTION: Failure to heed cautions may result in damage to your product.
Yi Please read this instruction manual before using this product.
Y All Ride Designs support surfaces are designed to help reduce the incidence of
pressure sores. However, no back support can completely eliminate sitting pressure or
prevent pressure sores. The Ride Corbac is not a substitute for good skin care including
proper diet, cleanliness, and regular pressure relief techniques.
Y Installation of any back rest on your wheelchair might alter your center of gravity within
the wheelchair. A recessed back position might cause the wheelchair to tip backwards,
potentially resulting in injury. Always assess the need for anti-tippers or amputee axle
adapter brackets to be added to your wheelchair to help increase stability. Similarly,
a more forward back position might reduce the forward stability of the wheelchair,
increasing risk of tipping forward, with potential for injury.
Y Do not use your Corbac without the spacer mesh overlay in place.
Y Do not lift the wheelchair by the Corbac.
Y Improper placement or securement of the Ride Corbac to your wheelchair may result
in injury.
Y This product should be installed and fitted by a qualified and competent healthcare
professional. Failure to accurately assess and adjust the fit of the Corbac could result in
injury to the user.
Installation and Use Instructions
It is recommended that a therapist or authorized Ride Designs supplier conduct the initial
fitting of your back support. Your Ride Corbac is designed to enhance core trunk stability
by providing posterior and lateral support to the lower trunk, lumbar spine, and pelvis
(ie, the core). The Corbac Adjustable Mount uses straps to achieve the initial support
for balance and alignment. The thoraco-lumbar-pelvic (TLP) supports provide additional
posterior-lateral support and the Corbac’s spacer mesh overlay provides a lightweight
cushioning support to facilitate moisture vapor transport while reducing shear.
The Corbac consists of four components: 1) the adjustable mount, 2) two thoraco-lumbar-
pelvic (TLP) supports, 3) the spacer mesh overlay and 4) four mounting clamps.

Initial wearing schedule
Prior to prolonged sitting, it is advisable to use your Ride Corbac for a short period of
time and visually check any area that contacts the back support. Any reddened area
should fade within 10-30 minutes. Contact your doctor or therapist if redness persists for
greater than 30 minutes. As long as skin inspections do not show red areas persisting
more than 30 minutes, you are safe to continue use. Skin checks should be made no less
than daily, even after skin tolerance is established. Continue to perform routine intermittent
pressure relief techniques (forward lean) as advised by your healthcare professional.
Y WARNING: If any redness associated with the use of the Corbac persists for greater
than 30 minutes, cease using and contact your therapist or doctor immediately.
Follow-up
It is recommended to have your seated posture and skin integrity checked by your
healthcare professional at least annually, or whenever you experience a change in
your weight, posture, or general condition that could impact your ability to sit safely,
comfortably, and functionally.
