Application
2.1.2.1 Definition of terms
AFB (Automatic Forearm Balance)
The AFB flexion aid stores the energy that is released when the prosthetic arm is extended and uses it to assist
with flexion. The complex mechanism of the flexion aid controls the dynamics of forearm movement and equalises
the leverage forces that develop via a compensation gear. As a result, the patient only has to exert minimal force on
the flexion cable or through body momentum. The compensation coefficient can be easily adjusted to the individual
weight of the prosthetic forearm and different clothing.
Lock
The product is either locked mechanically or electronically (see Page 11). The internal ratchetless lock can be
unlocked or locked in any position, even under a load. The product has a load capacity of up to 230 N in the locked
state (this value may decline over the course of several years due to wear and tear). The lock will slip under higher
loads.
Mechanical lock
A strong pull on the cable (audible clicking sound) locks or unlocks the joint.
Thanks to the integrated compensation mechanism, the lock can be released with little effort, even under load. The
integrated strain relief reduces the risk of damage when the pull cable is pulled too hard.
Electronic lock
The lock can be released and engaged using electrode signals or switch signals (depending on the chosen switch­
ing version).
Slip-stop function
The slip-stop function makes it possible to lower the forearm in a controlled manner without having to fully release
the lock.
Slip-stop function, mechanical
A gentle pull on the cable (no audible click) unlocks the product so the forearm can be moved continuously. When
the pull on the cable stops, the product is locked again.
Slip-stop function, electronic
The slip-stop function is activated by the electrode signals (depending on the chosen control version). When the
electrode signal stops, the product is locked again.
