Description

Das Vierachkniegelenk ist für exoskeletäre Anwendung bei Verlust der unteren Extremitäten bestimmt ( )The quadriparticle is intended for exoskeletal use in the case of loss of lower extremities ( )

Dient zum gelenkigen Verbinden des Oberschenkel-Schaftes mit dem Fuß-Unterschenkelmodulen als Einheit einer Oberschenkelbeinprothese.Used to articulate the thigh-shaft with the foot-lower leg modules as a unit of a femoral prosthesis.

Das Vierachskniegelenk beinhaltet folgende Produktspezifische Merkmale:

  • 1. Seitenlenkern (Fig. 1), welche hintereinander parallel, in der gleichen Höhe oder versetzt angeordnet sind ( )
  • 2. Die Mehrachs-Gelenk-Kette sorgt für ein hohes Sicherheitsgefühl beim amputierten Anwender. Der Benutzer muss jedoch in der Bewegung einen starken Widerstand überwinden. Das ergibt ein sehr hohes Losbrechmoment.
The four-axis knee joint includes the following product-specific features:
  • 1. side links (Fig. 1 ) which are arranged one behind the other in parallel, at the same height or offset ( )
  • 2. The multi-axis joint chain ensures a high sense of security for the amputee. However, the user has to overcome a strong resistance in the movement. This results in a very high breakaway torque.

Bei dem HAPS Vierachsgelenk sind die Seitenlenker (Fig. 1) überkreuzt angeordnet.In the HAPS four-axle joint, the side links (Fig. 1 ) crossed over.

Der vordere Seitenlenker (Fig. 1), ist von den Drehpunkten (Fig. 2) höhenversetzt. Diese Konstruktion ermöglicht eine höhere Sicherheit ohne des Losbrechmomentes (Widerstand).The front side handlebar (Fig. 1 ), is from the pivot points (Fig. 2 ) offset in height. This construction allows a higher safety without the breakaway torque (resistance).

Das HAPS Vierachsgelenk kann in folgende Spezifikationen hergestellt werden:

  • 1. rechte oder linke Variante (für rechte oder linke Beinamputation)
  • 2. mit einem Seiten-Versatz (Fig. 3) vom 5–9 mm
  • 3. geschlechterspezifisch (für Mann oder Frau)
  • 4. Kindervariante
The HAPS four-axle joint can be manufactured in the following specifications:
  • 1st right or left variant (for right or left leg amputation)
  • 2. with a page offset (Fig. 3 ) from 5-9 mm
  • 3. Gender specific (for man or woman)
  • 4th child variant

Als Dämpfertechnologie können in diesem Gelenk folgende Bauteile verwendet werden:

  • 1. Karbonkraftblatt
  • 2. Elektronikdämpfer mit einstellbarer Ausgleichsreserve (Fig. 4)
  • 3. Gasdruckfeder
As damper technology, the following components can be used in this joint:
  • 1. carbon power sheet
  • 2. Electronic damper with adjustable compensation reserve (Fig. 4 )
  • 3. Gas spring
