Abstract: The invention relates to a prosthetic foot comprising a main body (10), a proximal connection device (15) for connecting the prosthetic foot (1) to a further prosthesis component, and a foot-front component (12) which is pivotally mounted on the main body (10) and which is associated with a resistance device (20), which resistance device retards plantar flexion of the foot-front component (12), wherein the foot-front component (12) is mounted on the main body (10) via at least one resilient component (30, 31, 32) which moves the foot-front component (12) back into a starting position after a deflection.

Abstract: The invention relates to an orthopedic device with an energy storage device 2 that comprises at least one cylinder 4, in which a first cylinder chamber 6, a second cylinder chamber 8, which is fluidically connected to the first cylinder chamber 6 by at least one fluid line 14, and a piston 10 are located, wherein the piston 10 is arranged relative to the cylinder 4 such that it can be displaced in such a way that by displacing the piston 4, an operating medium, which is a fluid, is conveyed through the at least one fluid line 14 from one cylinder chamber 6, 8 into the other cylinder chamber 8, 6, wherein the energy storage device 2 has at least one compensation volume 24, which is fluidically connected to the fluid line 14 via a fluid connection 22, and a first controllable valve 26, by means of which the fluid connection 22 can be opened and closed.

Abstract: A foot prosthesis having a lower-leg connection part, a foot part, a connecting element with a joint function which connects the lower-leg connection part to the foot part, and a release device, which controls movement of the foot part in relation to the lower-leg connection part. The release device includes an inhibiting device that is designed in such a way that a dorsal extension motion of the foot part in relation to the lower-leg connection part in an angular range from a maximal plantar flexion position to a zero position is inhibited less intensely than a dorsal extension motion of the foot part from the zero position.

Abstract: A prosthesis with a lower limb attachment part, a foot part, a connection element with a joint function that connects the lower limb attachment part with the foot part, and a release device which can be brought into a locking position in which the foot part and the lower limb attachment part are connected to each other in a rotationally fixed manner at least relative to a dorsal extension movement, and into a release position in which the foot part can be rotated relative to the lower limb attachment part. The release device is designed to passively switch from the locking position into the release position when a variable which correlates to an ankle torque (M) in the connection element lies above a pre-set threshold.
