WC20 Information

WC20 Hardware

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 WC20 approved.

CAUTION: The WC20 approved Q-Back 2.0 should only be used as detailed in these instructions, and only meets WC20 requirements when used in conjunction with a WC20-approved seat back and wheelchair.

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

Clients who use wheelchairs should transfer to the vehicle seat and use the vehicle-installed occupant restraint systems.
Prior to transporting, always double check the tie-downs and hardware.
On tie-downs and restraints, look for tears or worn webbing straps.
Replace as necessary and never use torn straps.
Look for damaged hooks or loose tie-down hardware.
On the seating system, check for loose screws attaching the hardware to the seat. These should be snug and not overly tightened.

WARNING

The WC20 approved Q-Back 2.0 is designed specifically for occupancy when used on wheelchairs that are facing forward in motor vehicles.
The WC20-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 position vehicle-anchored belt restraints on the wheelchair passenger, and b) the degree to which proper positioning of belt restraints can be achieved.
Alterations and substitutions should not be made to the seating system or to its parts and components without consulting the manufacturer.

Belt Placement

The pelvic belt should be worn low, across the front of the pelvis near the junctions of the pelvis and 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 junction 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 mid-line of the occupant.

Proper Positioning of Belts on Occupant

Stealth-Products-Q-Back-2-0-6-Inch-Lateral -Depth-for -Quantum -Power-
Chairs-fig-5

Upper torso belt restraints should fit directly over, and in contact with, the middle of the shoulder.

_ 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.

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

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.
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 occupant’s shoulder and chest.

Trays

Wheel chair 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 positioned with a gap of at least 75mm (3 in.) 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

Stealth-Products-Q-Back-2-0-6-Inch-Lateral -Depth-for -Quantum -Power-
Chairs-fig-8

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 crash-worthy 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 requirements of 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.

When mounting the WC20-approved Q-Back 2.0 to your wheelchair, refer to the installation instructions.

WARNING

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
The WC20-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.

CAUTION
