6.6 Adjusting Centre of Gravity of Seat

Centre of gravity of seat can be adjusted by mounting seat
frame farther towards front or rear on seat.
WARNING!
The seating system of the mobility device is
delivered ex works with an optimally adjusted
centre of gravity (CoG). Any change in this
adjustment setting can negatively influence the
stability of the mobility device.
– You must perform an individual risk analysis
every time you change the centre of gravity
of the seating position, in order to ensure the
safety and stability of the mobility device.
A: Seat depth
B: Centre of gravity of the seat / seat position
The user weight and seat depth have strong
influences on the choice of the centre of gravity
(CoG). If the user is heavy and the seat depth is
greater, the focus should be the farther back. For
best possible driving characteristics of rear-wheel
drive wheelchairs, the weight to be distributed: 30
– 40 % front and 60 - 70 % rear.
