Lower leg length
Release the locking device by loosening the knurled nuts on the right and left of the footrest. The height of the footrest
can be freely adjusted. (fig. 12)
Foot angle
Loosen the four screws on the right and left of the rear side of the footrest and adjust the desired foot angle. Retighten
the screws. (fig. 13)
Knee angle
Set the knee angle by loosening the side wing screws (on both sides). (fig. 14)
Tip: The footrest can be flipped up to facilitate getting on and out of the chair.
Parking brake function
Locking / releasing the castors
The rear castors are equipped with easily accessible and easy to use brakes. To lock the castors press the locking device
down. By pushing the locking device up again the castors become flexible. The brakes prevent the castors both from
turning and from swivelling, so that the base frame can be safely parked via the rear wheels alone (fig. 15).
Spring element
The movable spring elements allow and facilitate the children’s individual mobility. (fig. 16)
Angle of rotation
Loosen the central Allen screw at the back of the seat unit and adjust the desired angle of rotation of the spring element.
Retighten the screw. (fig. 17)
Note: To dismount the whole spring element, loosen the central Allen screw and remove the spring element in
forward direction.
Depth adjustment
In order to adjust the depth in the direction of the child, loosen the Allen screw for the adjustment of the rotation angle
(s. above). Now the upper and lower Allen screw at the back of the seat unit can be turned to the right, and the whole
spring element moves forward in the direction of the child. If the Allen screw is turned to the left, it moves back again.
After adjustment, the central Allen screw (for the rotation angle) should be retightened. (fig. 18)
Spring movement limiters
The red spring movement limiters are located inside the spring element. The displacement of the FGF track can be limited
as required.
To limit the spring travel, press the securing device inward until it engages into place. Press outward for loosening. (fig. 19)
The adjustment of the spring movement limiters may be restricted when the belt bow is used. In such cases, slightly press
the spring element forward.
Tip: Slightly lift the FGF track from the front for easier adjustment.
FGF-track (flexible fibre glass track)
These tracks are made of fatigue-proof material using the latest fibre glass technology (pultrusion). Apart from high
durability, they also ensure optimal sitting comfort, which results in the child’s positive perceptive process.
Wing suspension
The wing suspensions optimally fit the body contour of the child and transmit movement impulses. Each wing suspension
may be shifted or removed as necessary in order to ensure individual adaptation. To remove the wing suspension, press
the top and bottom forward with both hands.
