PROCEDURE 17FWD WHEELCHAIRS
ADJUSTING WEIGHT
DISTRIBUTION (FIGURE 13)
NOTE: Depending on the seat depth ordered, the position
of the seat support brackets is factory set between 2.25 and
6 inches (measured from the front of the base frame to the
front of the seat support brackets). This will put approximately
65% of the total weight of the chair and user over the drive
wheels (large wheels), allowing for the best performance of
the chair.
In order to achieve maximum comfort and maneuverability
for the end user, it may be necessary to adjust the seat
support brackets slightly forward or backward. It is recom-
mended that the seat support brackets be set as close to
2.25 - 6 inch mark (depending on seat depth) as possible,
while allowing maximum comfort and maneuverability to
the end user.
Adjusting Weight Distribution For New Seat
Depth
NOTE: When changing the seat depth of the chair, it is
necessary to adjust the seat support brackets in order to
achieve optimum weight distribution (65%). Perform the
following procedure to adjust the seat brackets:
1. Refer to the following chart to determine the correct
position of the two (2) seat support brackets to achieve
optimum weight distribution (65%).
2. Loosen the four (4) mounting screws that secure the
two (2) seat support brackets to the base frame.
3. Adjust the two (2) seat support brackets forward or
backward until the position determined in STEP 1 is
achieved.
NOTE: When the front of the seat aligns with the controller,
approximately 65% of the total weight of the chair and user is
over the drive wheels (large wheels).
4. Adjust the two (2) seat brackets slightly forward or
backward, until maximum comfort and maneuver-
ability for the end user is acheived.
5. Retighten the four (4) mounting screws securing the
two (2) seat support brackets to the base frame.
