Accessory HEADREST and MOUNTING
INSTALLATION and ADJUSTMENT
Arange of ball mounted Headrests, with angle adjustable stems, is available
for use with the caddy Seating System and requires an appropriate mounting
bracket to be fitted to the rear face of the Backrest Panel. The Panel is pre-
drilled to accept various mounting brackets available from RMS Ltd.
(The Mounting Boss L4-P44 shown in Fig.25, is capable of accepting both 13mm
and 16mm standard square Headrest Stems).
3 & 4mm Hex. Keys. 13mm Spanner.
As installation of a Headrest Mount requires
access to the front and rear of the Backrest
Panel, the user should be removed from the
seat unit.
Temporarily remove the Backrest Upholstery
from the Backrest Panel.
From the rear of the Backrest, slacken both
securing screws for the Backrest Height
Adjustment Panel, refer to Figs.3 & 5 and
raise Panel to it’s highest point to expose the
Headrest Mounting holes required.
(If using the Mounting Boss shown in Fig.25,
the four centre holes will be required).
Remove all four screws from the Mounting
Boss and hold the Boss assembly against the rear of the Backrest Panel with the
13mm square receiver hole at the top when a 13mm Headrest Stem is being
used, or 16mm hole at the top if using a 16mm square Stem. Insert each of the
previously removed four screws, through
from the front of Backrest Panel and
screw into the Mounting Boss.
Fully tighten all screws evenly sufficient
to prevent any movement.
Re-secure the Backrest Height
Adjustment Panel in it’s previous position
and re-attach the Backrest Upholstery.
Headrest height adjustment can be made
at both the Mounting Boss and Link pivots
Fig.25. Forward adjustment can also be
made at the Link pivot points.
Swivel adjustment can be made at the
Headrest Ball Mount Fig.26.
With the Headrest Stem inserted into the
Mounting Boss to the required position,
fully tighten the Locking Thumb-screw
Fig.26. The Height Pre-set Collar, when set, enables the Headrest to be refitted to
the same height after each removal.

Where there is limited access to the underside of the Seat Base Board and
to improve the adjustability of the Pelvic Supports and/or Knee Adductors
(where fitted), it is advisable before finally attaching the Seat Base Board, to
reverse the mounting screws i.e. to be inserted from the top of their
brackets and screwing into the their threaded plates which will now to be
located on the underside of the Seat Base Board, with the threaded bosses
pointing downwards.
Finally attach the caddy Seat Base Board to the wheelchair seat frame using
the screws supplied, with large washers under their heads and where possible
on the underside of the frame and secure with Nylock nuts.
Although spacers are supplied for use between the caddy Seat Base Board
and the mounting points on the wheelchair frame Figs. 8a & 8b, these may
not be required for all applications
Please liaise with RMS technical team, should any difficulties arise at this stage.
