The QRT Deluxe wheelchair restraint and occupant restraint safety systems were the first self tensioning, self locking, wheelchair transport mobility products introduced. The operator has the discretion of further tensioning the wheelchair straps with the dual knobs located on both sides of the retractor. The capability to deliver continuous adjustment to the wheelchair straps reduces the potential for wheelchair backflip or securement disengagement resulting in greater passenger safety. The popularity of the QRT Deluxe wheelchair restraints is evident in installations raging from municipal transit systems and paratransit agencies to handicap minivans. The innovative features built into the QRT MAX have notable improved wheelchair transport and disabled access.
