17.3 Adjusting the tipping point
Optimum product tipping behaviour
is
achieved 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 must be pre-
vented from tipping over backwards by means
of anti-tipping supports.
To ensure safe operation, the
tipping point
setting
should always be selected to suit the
wheelchair user's individual requirements and
abilities.
17.3.1 Inlet types
The tipping point is set by changing the hori-
zontal position of the wheel plate on the frame.
Figure 9: Inlet and wheel plate (view from inner side
of product)
The wheel plate is mounted on the lower frame
tube using three M6 fixing screws and one inlet
in the frame. With the inlets, differentiate be-
tween the long and short inlets. The selection
of the inlet is orientated, e.g. to the seat width,
the weight of the wheelchair user, the type of
wheel plate or the 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
As an assembly aid, the short inlet has a
thread in the end face and the long inlet does
not.
Figure 11: Long inlet without and short inlet with
thread in the end face
The following features indicate if a long or a
short inlet is installed: With the short inlet, a
tube plug is applied to the end of the frame, the
long inlet does not have one.
