To attach the Pelvic Belt using
RMS
frame clamps
MC123
(Fig.1), install the clamps, together
with any appropriate size spacer shim, onto the frame tubes in the most suitable position to
create a 45° directional line over the pelvis (see Diagrams below). NOTE: ensure the locating
lugs on any spacer shims engage into the slots in the Clamp.
MC123
Clamps are suitable for
use with both Tri-slot and Cam Lock Mounting Plates.
When using
Tri-slot Mounting Plate
method of
attachment, Figs.2 & 4, install a Tri-Plate onto each
free end of the Belt by threading the end of the webbing
through the slots as shown in Fig.4. (Do Not adjust at
this stage). Insert the clamping screw through the Tri-
slot Mounting Plates (from the side which is marked
CE , RMS and is recessed to take the screw head) and
screw into the M6 captive nut in each Clamp. Tighten in
line with the direction of pull. Screws should be
tightened sufficient to prevent any movement of the
Clamps, although this may allow the Tri-Plates to
revolve around the screws, with some resistance.
Adjust belt lengths as required and pull webbing tight against Tri-Plates.
When using the enclosed
Cam Lock Mounting Plate
method of attachment, Figs.3 & 5, install a Mounting
Plate onto each free end of the Belt by raising the
Cam Buckle cover, threading the end of the webbing
through the Cam Buckle side of the Mounting Plate,
around the bridging bar, then back through Cam
Buckle as Fig.5. (Do Not adjust at this stage).
With the Cam Buckle cover raised, insert clamping
screw, with washer through each Cam Lock Mounting
Plate and screw into the M6 captive nut in each
Clamp. Tighten in line with the direction of pull.
Tighten screws sufficient to prevent any movement of
the Clamps , although this may allow the Cam Lock Mounting to revolve around the screws, with
some resistance. Adjust belt lengths as required and close Cam Lock Mounting cover to secure.
USER POSITIONING
[cont]
Belt positioned above the Pelvis against soft
tissue area of Lower Abdomen.
The Hips are forward in the seat giving a
reclined posture.
The Belt will not generally stop the person
slipping down in the seat.
Incorrect position can be caused by:-
The occupant being unable to attain a 90°
sitting position.
The occupant slipping down in the seat due
to inappropriate fitting / adjustment or the
belt being held away from the occupant by a
part of the seat system (e.g. belt over top of
armrests or over hip / thoracic supports.

USER POSITIONING [cont]
ADJUSTMENTS
As the positioning and tension of a Pelvic Belt is
extremely important to achieve its intended purpose, care
should be taken to ensure that all straps are attached with
the correct direction of pull, appropriately adjusted with any
Comfort Pads suitably positioned.
Incorrect tension, i.e. too tight, can result in unnecessary
discomfort or distress to the User, whereas too loose, can
allow the belt to roll upwards or downwards thus not achieving its intended purpose. This
could also allow the buckle release catch to come into contact with a more rigid piece of
clothing, i.e. a large button or belt buckle, which in turn could inadvertently operate the
release catch on the Belt. Should the User show continued signs of discomfort or distress due
to the Pelvic Belt a suitably qualified person should be consulted immediately.
For
“Single Pull”
type belts, adjustment is
made after connecting the main buckle, by
pulling the strap fitted with a “D” ring to the
side of the main buckle, outwards away
from the centre.
With
“Dual Pull”
type belts, adjustment is
made, after connecting the main buckle, by
equally pulling, the “D” ring straps located at
either side of the main buckle, outwards
away from the centre.
For
“Rear Pull”
type belts, adjustment is
made after connecting the main buckle, by
pulling the “D” ring straps located towards the
rear of the Comfort Pads, in a forward direction,
thus creating a rearward pull on the Pelvic
Belt.
Due to the nature of the use of this style
of belt, the
“Twin Lock”
has no length
adjustment available at the Main Buckle.
Any adjustments to the belt length,
can be made at each fixed end of the
belt via the Tri-slot mounting plates.
NOTE:
The Pelvic Belt length may require adjustment periodically to allow for User growth,
changes in the User’s disability or changes in seasonal clothing. Adjustments to the belt length
can be made at the main buckle, with further adjustment available at each fixed end of the Belt
via the Tri-slot mounting plates or Enclosed Cam Lock mounting plates.
Occupant in, or near, 90° sitting position.
Posture / safety belt fixed near to corner of
seat base, with a snug fit over the Pelvis at
45°.
