Congratulations on purchasing your new Convaid transit wheelchair, proven
safer for use as seating aboard a motor vehicle. This guide includes important
information regarding the use of your transit wheelchair. Please read it care-
fully and keep it for future reference.
When riding aboard a motor vehicle, it is preferred that the wheelchair user
transfer from the wheelchair into the vehicle manufacturer’s seat and use a
federally approved, crash-tested restraint system. However, it may be unde-
sirable for some wheelchair users to transfer to the seat provided by the
motor vehicle manufacturer. In these cases, Convaid transit wheelchairs offer
a safe alternative.
All Convaid transit wheelchairs comply with a transit wheelchair standard
that requires wheelchairs to be dynamically crash tested. (Largest and small-
est sizes of each model have been crash-tested at a leading U.S. university;
intermediate sizes may be certified to standard by Convaid.) Proper use of
your Convaid transit wheelchair will significantly reduce the likelihood of
injury in the event of a motor-vehicle accident.
This guide provides instructions on how to correctly secure your Convaid
wheelchair to the bus or van and safely restrain the wheelchair occupant.
When selecting a wheelchair, choose the size in accordance with the occu-
pant’s weight as shown in the following table.
Seat Width Occupant Weight Seat Depth
(in. / cm) (lb. / kg) (in. / cm)
10 / 25.5 35-66 / 15.9-29.9 9-11 / 22.86-27.94

INTRODUCTION
Introduction

1. The wheelchair should be used as indicated in the User’s Guide
instructions accompanying the wheelchair. Failure to do so
increases the likelihood of serious injury in a vehicle crash.
2. The five-point harness and a four-point wheelchair
tiedown system in compliance with SAE J2249 Wheelchair Tiedown
and Occupant Restraint Systems for Use in Motor Vehicles should be
used at all times during transit.
3. Use positioning belts or postural supports in a moving
vehicle only in conjunction with a crash-tested five-point harness
system. NEVER USE POSITIONING BELTS OR POSTURAL
SUPPORTS AS MOTOR VEHICLE RESTRAINTS, unless they have
been designed, tested, and labeled for this use. (See #4 below.)
4. Wheelchair-anchored lap belts intended for use as an occupant
restraint in a motor vehicle must comply with Section 19
ANSI/RESNA WC/Volume 1*, Wheelchairs Used as Seats in Motor
Vehicles, or “WC19.” Your Convaid transit wheelchair provides
the option of using a crash-tested, wheelchair-anchored five
point harness.
5. Whenever possible, auxiliary wheelchair equipment (such as an
oxygen tank) should be removed from the wheelchair and secured
in the vehicle during transit so that it does not break free and
cause injury to vehicle occupants during a crash.
6. Adequate clear zones are required for occupants restrained by
an upper- / lower-torso five-point harness. See Figs. 1 & 2.
7. Do not alter or substitute any part or component of the
wheelchair, wheelchair frame or wheelchair seating system.
8. If the wheelchair has been involved in a vehicle crash that requires
the vehicle to be towed, it may have been structurally damaged,
which could compromise its safety and effectiveness. Wheelchairs
involved in such incidents should be returned to Convaid for
inspection and evaluation.

Wheelchairs Used as Seating in
Motor Vehicles
Before attempting to use your Convaid transit wheelchair as a seat in a motor
vehicle, please take a moment to become familiar with some fundamental
principles of occupant safety:
Most serious or fatal injuries occur during frontal-impact crashes.
The primary cause of injury to motor-vehicle occupants in frontal
crashes is a lack of effective occupant restraint, which results in
contact with the vehicle’s interior components or objects and
structures outside the vehicle.
Effective protection of occupants in frontal impacts requires the use
of five-point harness that complies with federal safety standards and
WC19. The five-point harness should be positioned snugly across the
pelvis and should also be positioned snugly over the shoulder and
chest. And, the crotch strap length should be adjusted for proper
pelvic belt height. Harness restraints used in this manner also greatly
reduce the likelihood of injury during vehicle rollovers.
For belt restraints to be effective, the wheelchair must be effectively
secured to the motor vehicle, and the harness restraint must remain
in position on skeletal portions of the body and not place undue
stress on the abdomen.
ANSI/RESNA WC19
For a wheelchair to provide safe seating in a motor vehicle, it is essential that
it comply with the safety standard known as Section 19 ANSI/RESNA
WC/Volume 1, Wheelchairs Used as Seats in Motor Vehicles, or “WC19.”
Convaid’s transit wheelchairs comply with this voluntary transit wheelchair
standard and have been dynamically tested according to the
4
CONVAIDTRANSIT GUIDE
Passenger Safety

procedures of Annex A of the standard, which includes the use of a wheel-
chair-anchored five-point harness in a 30 MPH/20 g deceleration, frontal
impact.
The purpose of WC19 is to:
reduce the risk of injury to motor-vehicle occupants who remain
seated in a wheelchair during transit and
establish an industry standard so that wheelchairs that comply with
this standard will provide a reasonable measure of safe and suitable
seating during normal transportation and in a frontal impact.
The standard contains a number of design and performance requirements
specifically related to the use of wheelchairs as seating in motor vehicles.
Among the most important of these are that:
wheelchairs provide four easily accessible hook- or strap-type
attachment points for strap-type tiedowns with hook- or strap-type
end fittings to facilitate wheelchair securement in motor vehicles (see
Fig. 3) and
wheelchairs are crash tested at 30 MPH/20 g deceleration while
secured by a four-point strap-type tiedown and loaded with an
appropriately sized crash-test dummy. (Note that this is essentially
the same level of crash testing required by federal safety standards
for passenger motor vehicles.)
When you use your Convaid transit wheelchair as seating in a motor vehicle, it
is vital that you use a wheelchair tiedown and occupant restraint system
(WTORS) that complies with SAE J2249. As stated in this recommended prac-
tice, the wheelchair must be secured in a forward-facing configuration with a
J2249-compliant tiedown. The wheelchair occupant should be restrained by
the upper-/lower-torso five-point harness for optimal crash protection

PASSENGERSAFETY

Attach tiedown straps to securement points (red brackets) located on the
wheelchair’s legs in accordance with the WTORS manufacturer’s instructions.
Securement points are identified by the symbol in Fig. 4. and their location
on the wheelchair illustrated in Fig. 5. You must use all four tiedown
straps when securing your Convaid wheelchair in a motor vehicle.

WHEELCHAIRLATERAL STABILITY

The correct use of equipment that complies with SAE J2249 and ANSI/RESNA
WC19 may not prevent all crash-related injuries to wheelchair-seated occu-
pants, but it will greatly reduce the risk of serious injuries.
Securing the Wheelchair
When securing the occupied wheelchair, it is important that the WTORS
anchor points on the floor and wall of the motor vehicle are positioned proper-
ly according to the WTORS manufacturer’s instructions.
The wheelchair must be positioned facing forward inside the vehicle.
Position the wheelchair between the front and rear tiedown anchor points,
allowing for the correct angle of adjustment of the tiedown straps, as illustrat-
ed in Fig. 6.
Your Convaid transit wheelchair can be easily secured by four-point strap-type
tiedowns by attaching the hook end fittings of the tiedown straps to the four
red securement-point brackets located on the four tubular legs of the wheel-
chair or by threading tiedown straps through the openings in the securement
points.
The floor anchor points and wheelchair should be located:
so that the tiedown straps follow a straight, clear path from the
wheelchair securement points to the floor anchor points and
so that the front straps are angled outward from the sides of the
wheelchair (see Fig. 7) and
so that the rear straps are anchored straight back from the wheelchair
securement points
Once all four tiedown straps are attached to the wheelchair:
inspect all tiedown straps for signs of wear to the webbing and replace
any straps that are worn and
tighten the straps to remove any excess slack and provide tension
between the front and rear tiedown straps

Providing Clear Space & Padding
Position the wheelchair aboard the motor vehicle to ensure sufficient clear
space in front of, and behind, the occupant. (See Figs. 1 & 2) If there are
any hard or sharp objects or components near the wheelchair, such as compo-
nents of lifts or fold-up seats, they must be covered with heavy-duty energy-
absorbing padding to ensure the safety of the wheelchair occupant and other
passengers.
Restraining the Wheelchair Occupant
Your Convaid transit wheelchair was dynamically crash tested
in a forward-facing configuration using an appropriately sized
crash-test dummy restrained by an upper-/lower-torso five-
point harness. To reduce the possibility of head and chest
injuries resulting from contact with vehicle components, you
must use the five-point harness. (See Figs. 5, 7 & 8)
Your Convaid transit wheelchair provides for the use of a five-point harness,
which replaces the vehicle-mounted lap/shoulder belt. The five-point harness,
which has been dynamically tested in accordance with Annex A of WC19*,
comes standard on the chair. This harness is for children weighing less then
65 lbs, and increases safety because it is attached to the wheelchair rather
then the vehicle, providing a closer fit.
Before loading the wheelchair onto the vehicle lift, adjust and fasten the five-
point harness over the wheelchair user's upper / lower torso. The five-point
harness should be adjusted so the upper torso (shoulder) straps fit/attach to
chair just above the shoulders, the lower torso (pelvic) straps fit low over the
pelvis, and the crotch strap should be adjusted for proper pelvic belt height.
The straps should be adjusted as snugly as possible without
compromising comfort.
*(and proposed section 19 ANSI/RESNA WC/Volume 4)
CONVAIDTRANSIT GUIDE

Adjusting the height of the Shoulder Harness
1) Release the Upper and Lower Rear Lock Braces by lifting up on the center
of each individual brace.
2) Press in the silver snap button on the upper rear lock brace and lift the
lock brace out of the housing.
3) Slip the shoulder harness loop off of the brace and pull the shoulder har-
ness out through the seat upholstery.
4) Reposition the shoulder harness to the desired height, and reinsert it
through the seat upholstery.
5) Slide the shoulder harness loop on to the upper rear lock brace and rein-
sert the lock brace into the housing. Repeat steps 1-5 for the opposite side.
7) Lock the both the upper and lower rear lock braces by pressing down on
each individual brace.
Adjusting the Pelvic Straps
1) Adjust the crotch strap by pressing down on the gray push button, and
pulling on the end of the strap
2) Adjust the pelvic belt straps by either pulling on the loop located at the
end of the strap (tighten), or pulling on the end of the strap closest to the
buckle (loosening).
If the wheelchair user elects not to use the five-point harness, a vehi-
cle-anchored lap and shoulder belt must be used. As with the wheel-
chair-anchored lap belt, it is
very important to position the vehicle-anchored lap belt low over the pelvis so
that the angle of the lap belt is within the preferred zone of 45°to 75°to the
horizontal or the optional zone of 30°to 45°to the horizontal, as shown in
Fig. 11. Be sure that the shoulder belt crosses the chest and the middle of
one shoulder and that belt restraints are not held away from the body by
wheelchair components or parts, such as armrests or wheelchair legs. (See
Fig. 12) Thread the lap belt under the frame tubes located directly under the
user’s elbows and pull the belt snug against the pelvis. Ensure that belt web-
bing is not twisted as this may compromise safety.

PROPERUSEOFEQUIPMENT

Using Postural Belts & Supports
Positioning accessories such as pelvic positioning belts, anterior trunk sup-
ports, and lateral trunk supports may be used while in transit, but are not
designed to provide restraint during a crash. Postural supports and belts
should therefore not be relied on for restraint in a vehicle crash and
should be used only in conjunction with five-point harness that have
been designed for restraint in a motor vehicle and crash tested in
accordance with SAE J2249 and/or ANSI/RESNA WC/19.
Trays & Other Wheelchair Components
To reduce the risk of potential injury to the wheelchair user or
other occupants in a motor-vehicle crash, wheelchair-mounted
accessories, such as trays and respiratory equipment, must be
removed and secured separately during transit. Use tether
straps or other strong attachment hardware to prevent items
from breaking loose and causing injury during a crash. If it is
absolutely necessary to keep a tray on the wheelchair during
transit, use either a crash-tested foam tray, or an energy-
absorbing padding must be placed between the edge of the tray
and the wheelchair user to prevent serious injury during
a crash.

Note: Steeper side-view pelvic-belt angles
are especially important if the pelvic belt is
intended to be used for postural support in
addition to occupant restraint in a frontal
crash. Steeper angles will reduce the ten-
dency for a vertical gap to develop between
the user and the belt due to compliance of
seat cushions and belt movement, thereby
reducing the tendency for the user to slip
under the belt or the belt to ride up on the
soft abdomen during normal use.
Note: Steeper belt angles also reduce the
tendency for upper-torso belts to pull the
pelvic belt onto the abdomen during frontal
impact loading.

FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY CAUSE
DAMAGE TO YOUR WHEELCHAIR AND WILL INCREASE THE
LIKELIHOOD OF INJURY TO THE WHEELCHAIR OCCUPANT OR
OTHERS IN THE EVENT OF A VEHICLE CRASH OR EMERGENCY
MANEUVER.
The Convaid warranty listed in your wheelchair’s User’s Guide applies to your
transit wheelchair, with the addition of the following modifications:
This warranty is rendered null and void in the event that the wheelchair
frame, parts, or accessories are modified in any way (except by Convaid), or
if other than Convaid or Convaid-approved accessories are used, or if the
wheelchair is used in a manner other than that for which it was intended.
If the wheelchair is damaged in a motor vehicle accident, the warranty will
apply if the wheelchair is shipped by the original user to Convaid accompa-
nied by a copy of an official police accident report documenting that the
wheelchair was involved in a motor vehicle accident.
Due to normal wear and tear or after an extended period of use, your Convaid
transit wheelchair may no longer meet the original crash-test standards. To
ensure the safety of the wheelchair user, it is strongly urged that the wheel-
chair be returned to Convaid or its authorized dealer every three years for
inspection, service, and/or repair. Damage caused by misuse of the wheelchair
is not covered by the warranty and must be evaluated and repaired by
