Seat to floor height adjustment / limitations
The NEOX seat to floor height may be adjusted.
The overall range is from 13 inches to 20 inches
including all wheel configuration. With a specific
wheel configuration, the range of adjustment is 5
inches (as shown in Figure 4). Depending on the seat
to floor adjustment position, the maximum tilt may
be different because of mechanical interference.
The following chart shows the limitations due to
seat to floor adjustment for two center of mass
adjustment:

Note that this limitation does not include a possible interference with the armrest.

Tilt / recline stability limitation
Stability is a main concern for wheelchair.
Combining tilt and recline may cause instability.
In order to respect the typical 10 degrees of
stability in least stable configuration, a qualified
technician may have to limit the tilt and/or the
recline range of the wheelchair. The technician
can do so by adjusting the collet on the proper
gas spring.
Test were conduct using a reclining backrest to
define the maximum tilt /recline combination to
obtain a 10 degrees minimum angle in the least
stable configuration. The rearward stability was
the critical contributor. Tests were done with the
highest seat to floor height (worst configuration).
Figure 5 shows the rearward stability test.
The
table is given as reference only, results could
be influence by the anthropometry of the
patient.
