Abstract:
1. A prosthetic device for replacing a limb of a user, said prosthetic device comprising: at least one prosthetic portion; a prosthetic joint portion for being interposed between said prosthetic portion and another adjacent prosthetic portion or an adjacent limb segment of the user, said prosthetic joint portion providing said at least one prosthetic portion to pivot between flexion and extension movements relative to said another adjacent prosthetic portion or the adjacent limb segment of the user; a primary brake in operational communication with said prosthetic joint portion for generating a braking torque thereon during flexion and/or extension movements; and a force multiplier in operational communication with said primary brake and with said prosthetic joint portion, said force multiplier providing for transforming the braking torque into a pressure onto said prosthetic joint portion thereby allowing braking thereof, wherein during flexion said primary brake causes said force multiplier to generate an additional braking force on said prosthetic joint portion, but the force multiplier does not generate an additional braking force during extension.
