CHAPTER 15: TRANSPoRTATioN oPTioNS
In 2000, the American National Standards Institute, Inc. (ANSI) and the Rehabilitation Engineering and
Assistive Technology Society of North America (RESNA) adopted ANSI/RESNA Wheelchair Standards
Volume 1, Section 19 entitled “Wheelchairs Used as Seats in Motor Vehicles” (ANSI/RESNA WC/19).
ANSI/RESNA WC/19 was developed to establish design and performance requirements for wheelchairs
that will be used as seats in a motor vehicle.
Both ISO 7176-19 and ANSI/RESNA WC/19 provide a testing methodology for testing a wheelchair in a
simulated frontal impact collision at 30 mph (48 kph). One difference between ISO 7176-19 and ANSI/
RESNA WC/19 is that ISO 7176-19 permits the anthropomorphic test dummy to be secured using a
vehicle-anchored pelvic belt and a vehicle-anchored shoulder belt while ANSI/RESNA WC/19 requires
that the anthropomorphic test dummy be secured using a wheelchair-anchored pelvic belt and a vehicle-
anchored shoulder belt.
ISO 7176-19 and ANSI/RESNA WC/19 are intended to promote occupant safety and reduce the risk of
injury for motor-vehicle occupants who remain seated in their wheelchair during transit by improving the
crashworthiness of wheelchairs that conform to its requirements. In the opinion of the authors of ANSI/
RESNA WC/19, “a wheelchair that complies with all the requirements of this standard can be considered
to provide a reasonable measure of safe and suitable seating during vehicle ingress/egress, during normal
transportation, and in a frontal impact” (emphasis added). However, the authors of ANSI/RESNA WC/19
also noted that “wheelchairs that conform to the requirements of this standard should not be considered
to offer seating and occupant restraint that is equivalent to that provided by seats provided by the vehicle
manufacturer” (emphasis added). Similarly, the authors of ISO 7176-19 stated that wheelchairs “that
comply with this part of ISO 7176 will have additional features that provide increased levels of occupant
security and safety whilst their occupants are riding in motor vehicles.” Accordingly, ISO 7176-19 and
ANSI/RESNA WC/19 include numerous warnings to the effect that “wheelchair users should transfer to the
vehicle seat and use the vehicle-installed restraint system whenever it is feasible.”
Therefore, there are several important considerations that users of TiLite’s Transit Tie-Down Option must
keep in mind. First, ISO 7176-19 only tests for wheelchair performance where the wheelchair, secured
in the forward-facing position, is involved in a frontal impact collision at 30 mph (48 kph). It does not
test for wheelchair performance in any other type of collision, including, without limitation, side impacts,
rear impacts, rollovers or higher speed frontal impacts. Second, compliance with ISO 7176-19 does not
guarantee that the occupant will not be injured, even in a frontal impact collision at 30 mph (48 kph) or
less. In such an impact, the forces experienced are very severe and injuries can be sustained even if the
wheelchair performs exactly as required by the standard.
This Owner’s Manual contains detailed information regarding the exact configuration of the TiLite
wheelchairs that were subjected to the frontal impact and other tests required by ISO 7176-19. See
“Statement of Compliance/Specifications” below. The results of that testing apply only to the configuration
of the wheelchair as tested and described herein. Therefore, if you order your chair differently, such
as with a seating system manufactured by someone other than TiLite, you are hereby advised that
the wheelchair was not tested in such different configuration and should not be considered “transit
approved” by TiLite. Because TiLite has not tested the chair with such different configurations,
TiLite has no knowledge of how the product would perform in such configuration. Therefore, TiLite
makes no claims or warranties about the wheelchair’s performance in any configuration other than
the configuration described herein. TiLite has not authorized any person to make any such claims
or warranties on its behalf.
STATEMENT OF COMPLIANCE/SPECIFICATIONS
Twist wheelchairs equipped with TiLite’s Transit Tie-Down Option conform to the requirements of ISO
7176-19. Specifically, it has been tested in accordance with Section 5.2 (Frontal Impact), Section 5.3
(Accessibility of Securement Points Intended for Use with Four-Point Strap-Type Tie-Downs with Hook-
Type End-Fittings) and Section 5.4 (Accommodation of Vehicle-Anchored Belt Restraints) of ISO 7176-19.
