Check tipping stability
Any change in seating position can negatively influence
tipping stability of the power wheelchair. For this reason,
after adjusting the seating position, you should always
verify tipping stability of mobility device.
CAUTION!
Any changes to drive program can affect
driving characteristics and tipping stability of
mobility device.
– Changes to drive program may only be carried
out by trained Invacare® specialist dealers.
– Invacare® supplies all mobility devices with a
standard drive program ex-works. Invacare®
can only give a warranty for safe driving
behaviour - especially tipping stability - for
this standard drive program.
Tipping stability check
1. Set following angle on wheelchair:
• Recline 30°
• Seat tilt max.
2. Allow user to down in mobility device in a sitting
position that is typical for them.
3. Drive front wheels of mobility device onto a step
about 100 mm high. This can be done using a ramp,
for example (illustration B).
4. Make sure that front wheels are pointed backwards
compared to direction of travel.
5. Attach a reference weight of 8 kg to the push bar
(illustration B).
6. Verify that mobility device is at most in a balanced or
"floating" condition in this position. This means that
front wheels can slightly lose contact with ground, but
chair must not tip back onto its anti-tipper wheels. If
mobility device does not fall back onto its anti-tipper
wheels, tipping stability is OK. If mobility device falls
back onto its anti-tipper wheels, you must either:
• Shift center of gravity far enough forward that
chair does not fall onto anti-tipper wheels or
• Install adaptor
7. Repeat steps described above after each modification
to verify tipping stability.
