8.13 Lap belt (seat belt)
CAUTION
Incorrectly adjusted lap belt
Malpositions, illness, falling of the user due to installation/adjustment errors
► Do not modify the settings established by the qualified personnel. In case of problems with the adjustments
(unsatisfactory sitting position) please contact the qualified personnel who fitted the product.
► The lap belt has to fit closely but not too tightly so the user is not injured. It should be possible to slide two fin
gers comfortably between the belt and thigh.
► Have the 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 or different clothing.
The lap belt (seat belt) prevents the user from slipping and supports positioning.
It is installed on the product by qualified personnel if needed and adapted to the requirements of the user.
Information about subsequent acquisition and mounting is provided by the qualified personnel that handed over the
product.
Using the lap belt
1) Open the buckle.
2) Place the user in an upright, 90° seated position (if physiologically possible). Ensure that the back is up against
the back support pad (if physiologically possible).
3) Close the buckle.
4) The lap belt should be at an angle of about 60° to the seat bottom. The belt strap should run across the thighs
in front of the pelvic bones (see fig. 56).
Possible errors
•
The lap belt is positioned above the user's pelvis in the area of the soft part of the stomach.
•
The user does not sit upright in the seat.
•
If the lap belt is too loose, the user can shift/slide out to the front.
•
During the installation/adjustment, the lap belt is routed over parts of the seating system (e.g. over forearm
supports or seat pads). This causes the lap belt to lose its retaining function.
