Seat comfort
Good seating comfort depends on the needs and possi-
bilities available to each individual. The following general
guidelines here show what to consider when settings are
made.
Select a seat cushion with care. Aside from comfort, it has
an impact on stability and thereby freedom of movement.
Seat cushions also have different pressure distribution
qualities.
The back support setting is a combination of angles,
height and shape. This is why the angle settings and
height for the back support may need to be adjusted
when the back support cover is being adjusted.
Back support angle
The back support angle may need to be adjusted when
adjusting the shape of the back support upholstery.
Contact your dealer or your Technical Aids Centre.
Back support upholstery
The back support upholstery is adjusted with the user sit-
ting in the wheelchair.
•
Make sure the user is sitting as far back in the seat as
possible.
•
Support the pelvis by tightening the strap found just
below the lumbar region.
•
Then adjust the upper strap to provide the user with
upper body support and balance.
•
The other straps are adjusted to provide space for the
user’s posterior and follow the back’s natural curvature.
Risk of tipping: Always check the setting of the
the anti-tips.
Do not overtighten the upper straps as this can
prevent the cross-brace from unfolding properly,
i.e. the seat-frame tubes do not sit flush in the
sideframes.
Settings seat comfort
Seat cushion
•
Make sure that the correct seat depth is set.
•
Position the cushion as far back on the seat so that the
rounded corners end up between the back rails.
•
Measure a suitable seat cushion length and cut it accor-
ding to supplied instructions.
•
A more contoured seat cushion can be obtained by
using a comfort wedge which is placed in the cushion
cover’s pocket under the seat cushion.
Back support cover
•
Loosen all back straps, but make sure that the Velcro is
still stuck together.
•
Place the back support cover so that it covers the upper
edge of the back rails and forms a crease between the
seat and the back support allowing the user to properly
sit in on the seat.
