Engineering and Design of the Retractor Mobility Aid Securement System

More than a decade ago Ortho Safe invented the first retractor system with the vision that this is the best design to secure a wheelchair quickly and safely.
During the past year others have followed us, offering quite similar systems
one even looks like ours!
However, don’t be fooled by good advertisement gimmicks or looks.
Compare all the products, because they are not created equal.

The difference in Retractor Design and Safety
What is a retractor ? The retractor design which is used in the mobility aid securement
system application is quite simple. Webbing is stored on a winchtype spool and a coilspring controls the webbing movement. A brake shall always be engaged to the winchtype gear to avoid accidental release.

We recommend a positive locking retractor, in which the retractor brake is always applied so
that webbing will not move, without using the release leveler. Always use the handwheel to remove
any slack from the securement. Sure the retractorspring will recoil the webbing automatically,
but it can run into the retractor housing loosely, in which case the wheelchair will move.
The occupant of a loose chair will experience the feeling of a rough sea adventure.
Always apply wheelchair brakes, attach securement and
in addition remove any webbing slack by tightening the handwheel.

According to A.D.A. Standards there shall be no more than two inches of movement in the chair at any given time.
