WARNING
Do not expose this product or its system to excessive heat,
such as an open ame or sparks.
Only a qualied service technician may install the UniLink Headrest Hardware
and its accessories.
UniLink
Preparations
A critical component of a properly tted head
support system, the UniLink Headrest Hardware is
intended to connect to the wheelchair’s back,
providing the user the necessary support and
stability for their neck and head.
Designed to be compatible with all Stealth
Products’ ball mount-based pads, UniLink’s link-
style hardware provides ample adjustment for
Stealth headrests. Multiple planes of adjustment for
posterior, anterior, and angle allow full surface
contact while accommodating postural anomalies,
and individual link adjustment capabilities isolate
planes and angles, providing reinforcement to even
the most complex head support solutions.
The UniLink Headrest Hardware increases a
user’s ability to successfully engage in daily
activities, as well as promotes upright posture and
the maintenance of a healthy head position.

Set up a plan before beginning the installation.
This plan should take into account:
• Where the UniLink Headrest Hardware will be placed, as well as applicable
attachments and accessories; and,
• The amount of clearance necessary for other hardware and accessories.

• Four M5x0.8x12mm Button Head Screws for mounting to seat backs with threaded
holes.
This selection of screws should accommodate your installation needs. If you have

scope of this manual, please contact your supplier, or call us at the numbers listed
on the inside cover.
CAUTION
The use of improper tools may cause damage to the device.
Insucient tightening of fasteners may lead to discomfort
for the user or component failure.

Installation
For seat backs with two holes:
Place the seat back mount on the back of the seat and line up the center hole
on either side of the seat back mount with the holes in the seat. From the
front, insert the two M6 x 1 x 18 button head screws through the holes in the
seat back and through the mount. Thread the nylon lock nuts onto the screws
and tighten the mount to the back of the seat.
On seat backs with four threaded holes (image not shown):
Place the seat back mount on the back of the seat and line up the holes with
the threaded holes of the seat back. Use the M5 x 0.8 x 12mm button head
screws to secure the seat back mount to the seat back. Make sure the tips of
the screws do not protrude past the surface of the seat on the side opposite
the mount.
WARNING
An incorrect installation of UniLink headrest hardware or its accessories may
cause damage to the hardware and/or injury to the user.
CAUTION
Any connection must be secured with all included fasteners.
Use only the fasteners provided in the package.
The installation of alternate or additional parts to a wheelchair
could change its functional structure.
Thoroughly assess whether additional wheelchair safety features are
necessary to maintain chair stability and eectiveness.

8
Installation
Loosen the handle (A) of the seat back mount by turning it counterclockwise
and insert the headrest hardware shaft into the square receptacle.
A
B
If the shaft is too high or too low,
the stop collar (B) requires re-
positioning. Loosen it with the
M2 Hex Key and adjust the stop
collar to the desired position.
Tighten the set screw with the
M2 Hex Key to secure the stop
collar in position.
When the stop collar is in the
proper position and the shaft is
inserted fully into the seat back
mount, tighten handle (A) by
turning it clockwise until the
shaft is secure in the mount.
Making Adjustments
The UniLink Headrest Hardware can be
adjusted in three planes: depth, height and
angle. To adjust one of these planes,
loosen any of the three M5 screws using an
M4 Hex Key. Change the orientation of the
link and re-tighten the screw until snug.
To adjust depth, height, or
angle of the headrest, loosen
these three screws and re-
tighten them when the proper
location is reached.
CAUTION
Care should be taken when tightening fasteners. Over-tightening of
screws may lead to stripped threads and component failure.
