6.6 Checking/adjusting the seating centre of gravity

CAUTION

Improper adjustment of the seating centre of gravity

Tipping, falling from the seating shell / seating system due to incorrect adjustment

► Avoid extreme settings that could lead to tipping when adjusting the seat angle. ► For transfemoral amputees, shift the seating centre of gravity forward. This improves the stability of the mobil

ity 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.

15Discovery

Page 16

Settings

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.

Setting 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 system if these make it difficult to release and slide the interface adapter (see Page12).

2) Loosen and remove the screw connections between the interface adapter and seat bars (see fig.13, item1; see fig.14, item1).

3) Slide the interface adapter along the seat bars to the assumed seating centre of gravity (see fig.13, item2; see fig.14, item2).

4) Insert the screw connections into the appropriate slots between the interface adapter and seat bars and firmly tighten them to a torque of 10Nm (see fig.13, item1; see fig.14, item1).

5) Mount the seating shell interface with the seating shell / seating system on the interface adapter.

6.13 Adjusting the wheel adapter with 22"/24" drive wheels (custom fabrication version)

WARNING

Incorrectly adjusted wheelbase

Tipping over, falling of the user due to incorrect adjustment

► Only adjust the wheel adapter after completing the adjustments described above. ► Maximum stability is achieved when the frame is set in the lowest position and the rear wheels are set in the

rearmost position. Deviations from this setting reduce the stability of the mobility base for seating shells.

► Avoid extreme settings that could lead to tipping when adjusting the seat angle. ► Please note that with the rear wheel in a more forward mounting position and with an unfavourable body posi

tion, the user may tip backwards even on level ground.

► Position the drive wheels towards the rear for transfemoral amputees. This improves the stability of the

product.

► Changing the size and position of the drive wheels may cause the caster wheels to wobble at higher speeds.

If changes are required, verify the horizontal alignment of the main frame.

WARNING

Improper assembly of removable wheels

Tipping, falling over of the user due to wheels coming off ► After each assembly, verify the proper fit of the removable wheels. The quick-release axles must be firmly

locked in the wheel attachment.

INFORMATION

To change the position of the wheel adapter, the knee lever wheel lock first has to be loosened and subsequently readjusted ().

If 22"/24" drive wheels are installed, the wheelbase can be adjusted on a special wheel adapter. This has the fol lowing effects:

Position of the wheel adapter / drive wheel Effect

Shifting to the rear (farther away from the seating centre of gravity)

Larger wheelbase; tipping resistance increases; mobil ity base for seating shells is harder to tip backwards when crossing obstacles;

larger forces required for tipping

Shifting forward (closer to the seating centre of gravity) Smaller wheelbase; tipping resistance decreases;

mobility base for seating shells is easier to tip back wards when crossing obstacles;

lower forces required for tipping

The permissible positions of the wheel adapter on the main frame are determined by the wheel size:

25Discovery

Page 26

Settings

• permissible positions for 22" drive wheels (see fig.40, item 2)

• permissible positions for 24" drive wheels (see fig.40, item 3)
