7.13.2 Swinging anti-tipper

CAUTION
Improperly crossing obstacles
Tipping over, falling of the user due to improper operation
► Never cross obstacles such as stairs and curbs at a slant angle. Always approach obstacles head on (at an
angle of 90°).
The swinging anti-tipper allows the wheelchair user to safely overcome thresholds and lowered curbs without the
help of an attendant. It prevents the wheelchair from tipping and after overcoming the obstacle automatically
swings back to the rear.
The swinging anti-tipper is set for a ground clearance of about 20 to 30 mm (max. 50 mm) and so that the outer
arm of the anti-tipper projects beyond the largest diameter of the tyre.
Negotiating thresholds/lowered curbs
The arms of the swinging anti-tipper should hang down towards the floor and swing freely for negotiating
thresholds and lowered curbs (see fig. 53).
When ascending an obstacle, the arms of the anti-tipper hit the ground and prevent the wheelchair from tipping
over to the rear (see fig. 54).
When descending an obstacle, the front arm of the anti-tipper must protrude beyond the edge of the obstacle to
enable the anti-tipper to swing out of the way.
As the wheelchair continues to be pushed (forwards/backwards), the anti-tipper turns around its axis (see fig. 55,
item 1). Once the obstacle has been overcome, the anti-tipper swings back into the start position.
