5.6 Fitting a Butterfly/Chest 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.
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.
Fig 5.6.1
If the Snappi was not originally supplied with
a butterfly/chest harness then you will need
to fit the 20mm cam buckle fixing points (Fig
5.6.2) to the rear of the seat.
To do this: thread the supplied bolts and
washers through the holes in the webbing
straps and screw through the fixing holes in
the bar on the rear of the seat (Fig 5.6.3).
For a size 1 Snappi we recommend using
the inner holes, and for the size 2 Snappi
the outer holes. Tighten using a 3mm Allen
Key so that the cam buckles face outwards
