to achieve the best support and also the
most easy handling it is vital to do the
proper and accurate first time seating
adjustments.
Initial adjustments
start with normal relaxed seating position.
the aim is to have the centre of the users
knee joint aligned with the centre of the
leg support knee rotation centre - while
the user at the same time is having good
back support of his lower back - even
when the leg support angle is changed.
with this in mind start with:
seat deptH adjustments =
balancing tHe cHair
It is vital to adjust the seat depth correct.
adjustments to the seat depth change
the centre of gravity which effects the
balance of the wheelchair. centre of grav-
ity too far back= the wheelchair tips eas-
ily backwards. centre of gravity too much
forwards brings too much weight to the
F
front castors and it is very heavy to drive
and steer the wheelchair. proper adjusted
seat provide stability and good manoeu-
vrability of the wheelchair.
correct seat depth:
loosen the Velcro straps of the back sup-
port. check that the user is getting into
the chair firmly. adjust the back support
by pulling the straps of the Velcro. the
knees of the user should align with the
joint of the leg support both in height and
in depth - with 2 finger widths distance
between seat of the users leg.
the seat depth can be adjusted. chair-back hinge can be repositioned to adjust
seat depth backwards. extension pieces allow for increasing the seat depth in the
front. consider the wheelchair balance. see further information to seat depth ad-
justment on the next page and in wheelchair user manuals.
