Intended Use 8.0
Intended Use
The Flip-Down hardware offers a sleek design, strong resistance and an easy
flip-down mechanism which allows the headrest to flip down while staying
attached to the chair, eliminating misplacement. This has the added benefit of
helping to improve mobility related issues and transfers.
The ‘link’ style hardware has also been introduced to some of the flip-down
mount hardware. This hardware provides limitless adjustment for Stealth’s
headrests. Multiple planes of adjustment allow critical adjustment of anterior,
posterior, and angle. Separate links isolate adjustment planes and angles, while
individual link adjustment achieves the most complex head support solutions.
The stop collar allows the technician to easily and properly set the height
necessary for the hardware to be determined and prevents any unwanted
movement while in use. The FDM hardware makes positioning your head
support and positioning systems easy and rigid. Adjust it to the exact spot you
need and it will hold fast the position.

Step 2: Place the headrest hardware links in line with the thru and threaded triangles. The link aachment
points must be aligned with the ip-down slot on the vercal bar to ensure correct movement of the
ip-down sleeve.
Step 3: Align triangles and ghten the socket head screws back into place.
Step 4: Add Blue Locte to set screws to prevent loosening. Tighten the set screws. Ensure they are snug
