WC20 Information 10.0
WC20 Hardware 10.1
Q-Back 2.0 has met the requirements for ANSI/RESNA WC
-4:2017, Section 20 - Wheelchair Seating Systems for Use
in Motor Vehicles, commonly shortened to WC20 and
ISO16840-4 for international transportation requirements.
The back must have the thumb screw inserted and
tightened to be WC-20 approved.
WC20 establishes design and performance requirements and test methods for
complete seating systems that consist of a seat, back support, and attachment
hardware.
Before Transit 10.2
Clients who use wheelchairs should transfer to the vehicle seat and use the vehicle-
installed occupant-restraint systems.
Prior to transporng, always double check the e-downs and hardware.
On e-downs and restraints, look for tears or worn webbing straps. Replace as necessary
and never use torn straps.
Look for damaged hooks or loose e-down hardware.
On the seang system, check for loose screws aaching the hardware to the seat. These
should be snug and not over ghtened.
CA UT ION
The WC20 approved Q-Back 2.0 should only be used as detailed in
these instructions, and only meet WC20 requirements when used in
conjunction with a WC20 approved back and wheelchair.
DA NGER
The WC20 approved Q-Back 2.0 is designed specifically for
occupancy when used on wheelchairs that are facing forward in
motor vehicles.

3
WC20 Information 10.0
Belt Placement 10.3
 The pelvic belt restraint should be worn low, across the front of the pelvis near the
juncons of the pelvis and the thighs.
 The belt restraint buckle of three-point belt restraints should be placed in contact with the
occupant’s body and away from wheelchair components.
 The juncon of the shoulder belt and pelvic belt of three-point-belt restraints should be
located near the hip opposite the shoulder over which the diagonal belt crosses and not
near the midline of the occupant.
Proper Positioning of Belts on Occupant
 Upper torso belt restraints should t directly over, and in contact with, the middle of the
shoulder.
Shoulder Belt
Restraint
Pelvic Belt
Restraint
DA NGER
The WC-20 approved Q-Back 2.0 has been designed to accommodate
the proper use of vehicle-anchored belt restraints and the ratings of the
seating systems, with regard to a) ease of properly positioning vehicle-
anchored belt restraints on the wheelchair passenger, and b) the degree
to which proper positioning of belt restraints can be achieved.
DA NGER
Alterations or substitutions should not be made to the seating system or
to its parts and components without consulting the manufacturer.

4
WC20 Information 10.0
CAUTION
Belt restraints should be adjusted to fit as snugly as possible,
consistent with user comfort.
Improper Positioning of Belts on Occupant
Belt restraints should not be routed outside of the wheelchair wheels or over the
wheelchair arm supports and should not be held away from the body by wheelchair
components or parts.
SAFETY
Belt restraints should not be worn twisted or in a manner that reduces
the area of contact of the belt webbing with the occupant.

5
WC20 Information 10.0
Both pelvic-belt and shoulder-belt restraints that comply with RESNA
WC-4:2012, Section 18 and/or 4.6,5.2,5.3 or RESNA WC-4:2012, Section 19
should be used to limit occupant movement in a crash and reduce the
likelihood of occupant ejection from the vehicle and/or injurious contact of the
occupant with the vehicle interior.
The pelvic belt should be angled between 30° to 75° horizontally when viewed
from the side, and ideally between 45° to 75° horizontally, as shown in the
figure below.
WARNING
If the back support must be adjusted to an angle greater than 30° to the
vertical during travel, the upper shoulder belt anchor point should be
adjusted rearward to maintain belt contact with the wheelchair
occupant’s shoulder and chest.
WARNING
Back supports with adjustable recline angles should not be tilted back
more than 30° to the vertical during travel in vehicles unless necessary
for the medical and postural needs of the occupant.

6
WC20 Information 10.0
Trays
Wheelchair-mounted rigid trays that are not specifically designed for use during
travel in motor vehicles should be:
 Removed and secured separately in the vehicle.
 Secured to the wheelchair so they will not break free in a crash.
 Be posioned with a gap of at least 75mm (3in.) between the back edge of the tray and the
wheelchair occupant’s abdomen and/or chest so as not to interfere with proper
belt-restraint use.
 Have energy absorbing padding placed between the back edge of the tray and the
wheelchair occupant.
User Safety 10.4
The use of a postural pelvic belt attached to the wheelchair base or seat frame is
encouraged during travel, but these belts should be positioned so that they do
not interfere with the proper positioning of crashworthy belt restraints, and they
should not be relied upon for occupant protection in crash situations unless the
postural belt has been designed to comply with, and perform to, the require-
ments in 4.6, 5.2, and 5.3 of RESNA WC-4:2012, Section 19.
Sufficient forward and rearward clear space should be provided around the
wheelchair occupant.
The forward clear-space zone (FCZ) needs to be larger when a shoulder-belt
restraint is not used.

7
WC20 Information 10.0
When mounting the WC20-approved Q-Back 2.0 to your wheelchair, refer to the
installation instructions on page 1.
DA NGER
The WC20-approved Q-Back 2.0 is designed only for use with
wheelchair frames that have been successfully crash-tested to the frontal
impact requirements of RESNA WC-4:2012, Section 19
WARNING
The WC-20 approved Q-Back 2.0 must be used on a wheelchair frame
that provides four securement points and pelvic belt anchor points that
conform to the requirements of RESNA WC-4:2012, Section 19.
