Invacare®Transport Tie Down Options
Invacare transport tie down options have been tested to ANSI/RESNA WC V
ol. 1 Section 19 and go
beyond the traditional “securement” brackets on other wheelchair designs. The transport tie down
options include four tie-down locations that have been crash tested and are clearly marked for the
caregiver to see. The options also include a battery securement system that helps prevent batteries
from becoming dislodged in the case of an accident.
Invacare order forms will include two transport tie down selections, TRRO* and TRBKTS.** All Invacare
wheelchairs with TRRO have been tested and passed the ANSI/RESNA WC Vol. 1 Section 19 standard using a specific seating system and
configuration. See order forms and the owners manuals for more information.
TRRO includes four factory-installed transport brackets and a wheelchair anchored pelvic belt. TRRO has been crash-tested in accordance with ANSI/RESNA WC V
*
requirements for wheelchairs with a 168 lb. crash dummy, which corresponds to a person with a weight of 114 to 209 lb.
** TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has not been crash-tested in accordance with WC 19. Use these transport brackets only to secure an unoccupied wheelchair
during transport.
As of this date, the Department of Transportation has not approved any tie-down systems for transportation of a user while in a wheelchair, in a moving vehicle of any type. It is Invacare’s position that
users of wheelchairs should be transferred into appropriate seating in vehicles for transportation and use be made of the restraints made available by the auto industry
recommend any wheelchair transportation systems.
