A minimum of 1” (2.5 cm) of clearance should exist between the top of the later-
al support and the user’s arm pit.
a) To adjust the height, angle, or width of the lateral thoracic support
pads, loosen the top bolts and slide to correct width.Tighten bolt to
bolt plate. If more adjustment is necessary, loosen the internally mount-
ed bolts, and slide in the track to the desired height and width.The
angle is obtained by tilting the bracket as needed.Tighten the bolts.
b) To adjust the depth of the lateral thoracic pads, turn the middle bracket so
that the slots are on side.Adjust to desired depth. Re-tighten the bolts.
C. HEADREST
1. Mounting a headrest.
The Solid Seat Back has a headrest plate
mounted to it. Care should be taken to
use the proper screw length when
mounting.
2. To position the headrest use the double
clamp and the collar clamp (B,C,D) to
obtain the proper height and distance.
For clamp B use a 3/32 Allen set screw
(A) and a 3/16 Allen cap screw. Clamp B
positions the headrest forward and aft.
However, due to the vertical movement
of this adjustment, collar clamp D will
have to be moved in conjunction.
3. Retighten both the 3/16 Allen and the set
screws (A) with a 3/32 Allen wrench.
