Camber
Angle
What
Is Camber?
By
camber angle we
are
referring
to
the
vertical
angle of the
rear wheels.
By changing
this
angle, you dramatically affect
the
handling characteristics
of
your chair, and
it
should
al-
ways
be
done
by
your authorized Colours dealer.
We
discuss
it
for informational purposes
only.
There
are
several benefits of
a slight
camber angle. First,
it moves
the top of the
wheel
in
toward your body, positioning
the
push
rim
closer
to
you.
Th
i
s
means more efficient energy use
and
less
shoul-
der
abduction.
It
will
also
make your chair more directionally
stab
l
e
and
increase responsiveness when
turning.
Keep
in
mind
tha
t
more camber angle will increase
the
overall
width
of
your chair. Make
sure
you maintain
an
appropriate width
for your
everyday
environment.
Wheel Alignment
Toe-In
I Toe-Out
When you have determined
a
comfortable
and
functional
seat and
backrest angle, decided
on a
camber angle
and the
rear wheel
posi-
tion, it is
extremely important
that
you geometrically align
the
wheels.
Any
advanced adjustments made will
effect the toe-in
j
toe-out
angle
(the
horizontal angle of
the
rear
wheels).
On
a
wheelchair where
the
rear wheels
are no
longer
paralle
l
,
t
he
rolling
resistance
and
directional
stability
may be greatly compromised.
It
will
also
increase
tire wear.
It
is
critical
that the
dis
t
ance
between
the
real wheels,
as
measured
from
the center (front and
rear)
does not exceed
0-
0.25" toe-in (see diagram).
Adjustment
to the
wheel alignment should only
be
made
by an
authorized Colours
dealer
.
We discuss
it for
informational purpose
only.
