7.4 Adjusting the seating centre of gravity
CAUTION
Improper adjustment of the seating centre of gravity
Tipping, falling from the seating shell/seating solution due to incorrect adjustment
► Avoid extreme settings that could lead to tipping when adjusting the seat angle.
►
For users with transfemoral amputations, shift the seating centre of gravity forward. This improves the stability
of the mobility base for seating shells.
Checking the seating centre of gravity is required in order to ensure that the seat angle can be adjusted easily
when the user is seated.
In principle, the centre of gravity adjustment has the following effects:
Seating centre of gravity Effect
Too far in front of the pivot point Seat tilts far forward when it is unlocked;
high holding forces required during seat adjustment
Too far behind the pivot point Seat tilts far backward when it is unlocked;
high holding forces required during seat adjustment
Setting recommendations
The seating centre of gravity should be individually adjusted according to the clinical picture.
The qualified personnel has to decide whether it is better that the seat swings forward or backward when no hold­
ing force is applied while the locking mechanism is released. If possible, the attendant who will be using the mobil­
ity base for seating shells should be consulted here.
Adjusting the seating centre of gravity when using an interface adapter
The seating centre of gravity can be set by releasing the interface adapter and sliding it along the seat bars:
1)
If necessary: Remove the seating shell interface with the seating shell/seating solution if these make it difficult
to release and slide the interface adapter (see Page 8).
2) Loosen and remove the screw connections on the interface adapter and seat bars on both sides (see fig. 1,
item 1).
3) Slide the interface adapter along the seat bars to the assumed seating centre of gravity (see fig. 1, item 2).
4) Insert the screw connections into the appropriate slots and tighten them to
6 Nm
(see fig. 1, item 1).
5) Mount the seating shell interface with the seating shell/seating solution on the interface adapter.
6) Conduct a functional test of the seat tilt and locking mechanism:
→ Tilt the seat and lock it at various positions along the entire adjustment range.
→
Ensure that the seat tilt can move freely and the locking mechanism functions securely. The seat angle must
not be adjustable after letting go of the release lever.
7) Test the adjustment of the seating centre of gravity:
→
Sit the user in the seat with the help of an attendant.
→ Tilt the seat and hold it in position. Only low holding forces should be necessary with tilting.
Adjusting the seating centre of gravity
If the results are not satisfactory, the setting has to be readjusted without the user in the seat, as follows:
Problem Solution
Seat tilts far forward when it is unlocked;
high holding forces required during seat adjustment Slide the seat and interface adapter back
Seat tilts far backward when it is unlocked;
high holding forces required during seat adjustment Slide the seat and interface adapter forward
7.5 Adjusting the leg supports (option)
CAUTION
Improper adjustment of the legrests/footplates
Tipping over, falling due to user error
►
After changing the legrest/footplate settings, verify that the legrests/footplates do not collide with the caster
wheels at any of the seat tilt settings (seat angle adjustment).
► The distance between the legrest/footplate and the caster wheel must be at least
25 mm
