Transport Tie-Down Options
Invacare transport tie-down options have been tested to ANSI/RESNA WC Vol. 1
Section 19 and go beyond the traditional “securement” brackets on other wheel-
chair 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 prevents 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 W/C Vol. 1 Section 19 standard using a specific seating system and configuration. See order forms and
the owners manual 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 W/C Vol. 1 Section 19 Frontal Impact Test
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 wheel-
chair 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. Invacare cannot and does not
recommend any wheelchair transportation systems.
