17.2.3 General
instructions
When changing the angle of seat or front seat
height each time:
the wheel track of the drive wheels must
be checked and readjusted if necessary
(see chapter 21.2).
the caster wheel axle must be readjusted
(see chapter 22.4).
the brakes must be readjusted (see
chapter 25).
the backrest angle must be readjusted
(see chapter 18.1).
make sure the clearance under the footrest
is sufficient. Experience shows that this
should not be less than 4 cm. (see
chapter23).
if necessary, the height of the anti-tipping
support may have to be readjusted (see
chapter 24.3).
17.3 Adjusting the tipping point
An optimum tipping property of the product is
reached when the axle mount of the drive
wheels is close to the body centre of gravity. A
product adjusted like this can be driven with
little effort and it also makes it possible to
manage a slightly uneven surface or edges by
tipping slightly. Driving on both drive wheels
(doing a wheelie) is relatively easy to learn.
Inexperienced wheelchair users are prevented
from tipping over backwards by anti-tippers.
In any case, the setting should be made to suit
your individual requirements and ability to
ensure you can drive your chair safely.
17.3.1 Inlet
types
Setting the tipping point is carried out by
changing the horizontal position of the wheel
plate on the bottom frame tube.
Figure 9: Terminology
The wheel plate is mounted to the frame using
three M6 fixing screws and one inlet in the
frame. With the inlets, differentiate between the
long and short inlets. The selection of the inlets
is orientated, amongst others, on the seat
width, weight of the wheelchair user, type of
wheel plate or equipment (e.g., one-hand
operation, wheelbase extension). Depending
on the inlet length, then the procedure for
adapting the tipping point also differentiates.
Figure 10: Long and short inlet with wheel plate
The short inlet has a thread in the end face
and the long inlet does not.
