5.6 Fitting a Butterfly/Chest Harness or H-Belt Harness (Optional)
The Butterfly harness comprises a padded
section that sits against the user’s chest, two
shoulder and two bottom straps. Either the
shoulder or the bottom straps are locked in a
position to suit the user and then final adjustment
is made on the opposite straps.
The harness is designed to provide comfortable
postural support for the user.

Alternatively an H-Belt hanress is available, which
comprises 4 padded straps that join together with
a quick release buckle to provide easy open and
release of the harness.
Important:
The harnesses fitted are for postural
support only and must not be used as a vehicle
harness. Please see section 13 for transport
instructions.
