well as chest/shoulder straps.

7.16.3.1 Adaptation

CAUTION
Improper adjustments
Injuries, malpositions, illness of the user due to adjustment changes
► The belt system is an important part of an individual seating unit/seating solution. Do not modify the installa­
tion position and basic settings established by the qualified personnel.
► In case of problems with these adjustments (such as an unsatisfactory sitting position), promptly contact the
qualified personnel who fitted the product.
► Immediately consult the qualified personnel if you detect signs of discomfort or fear when using the product.
► Have the basic settings of the belt system checked regularly. Adjustments may be required due to the growth
of the user or because of changes in the course of the disease.
Small length adjustments of the belt by the user or an attendant (e.g. for clothing of different thickness) are pos­
sible.
Positioning the user in the seat
• Place the user in an upright, 90° seated position (if physiologically possible).
• Ensure that the back is up against the backrest padding (if physiologically possible).
• Applies only to upper body straps/vests, chest/shoulder straps:
– Ensure that the height of the backrest on the product is adjusted correctly. The top of the backrest must be
at the height of the shoulders.
– The belt system is intended to support the area of the upper body (breastbone) from the front. The upper
and lower straps have to be adjusted as needed.
– Ensure that the positioning system is not too close to the throat. Otherwise the upper straps have to be
readjusted.
Possible positioning errors
• The user's hips are not secured with a separate lap belt (see page 83).
• If the positioning system is too loose, the user can shift forward/slide down.
• The positioning system collides with devices, accessories or supply hoses during installation and adjustment,
restricting their functionality.
• Applies only to upper body straps/vests, chest/shoulder straps:
– The positioning system is too close to the throat, endangering the user.
– The positioning system makes contact with the user in the area of the soft part of the stomach (too low).
Adjusting the belt length
Notes on correct adjustment are found in the instructions for use included with the belt system.

7.16.3.2 Use

WARNING
Incorrect application
Throttling, suffocation or strangulation due to sliding forward/down in the product
► The belt system must be used at all times while riding in the product. Always use the belt system in combina­
tion with a correctly applied and adapted positioning lap belt to stabilise the pelvis.
► The belt system has to fit closely but not too tightly so the user is not injured. Sliding two fingers comfortably
between the positioning system and upper body should be possible.
► Ensure that the buckle lies in the middle of the body.
► Ensure that the belt system is not too close to the throat. Otherwise the upper straps have to be readjusted.
► Remove any objects or clothing which get caught.
