A magnetic locking actuator for a prosthetic or orthotic device is provided. The actuator includes a first component including one or more magnets and a second component including one or more magnets. The first and second components are coupled to separate portions of the device. The magnets allow for adjustment of a length of the actuator to adjust an angular orientation of the first and second portions of the device. When magnets in the second component are aligned with magnets in the first component having an opposite polarity, a position of the second component is fixed relative to the first component, locking the actuator. When magnets in the second component are not aligned with magnets in the first component having the opposite polarity, the position of the second component is adjustable relative to the first component, thereby allowing adjustment of the height of the actuator.

The invention relates to a prosthetic device for a lower extremity comprising a prosthetic food and a lower leg part secured to the prosthetic foot, as well as a device for manually adjusting an orientation of the lower leg part relative to the prosthetic foot, wherein an inertial angle sensor is arranged on the prosthetic device, which detects the orientation of the lower leg part in the space and which is coupled to an output device which in turn outputs the orientation of the lower leg part in the space or the reaching of a previously determined orientation with an output signal in a manner that can be perceived by a user.

A prosthetic foot includes a cap, a retaining element and a plurality of blades. Each of the plurality of blades includes a proximal portion coupled with the cap, a middle portion coupled with the retaining element and a distal portion extending outwardly from the retaining element.

A prosthesis or orthosis device includes a knee joint connectable with the user's leg; a swing storage spring-gear mechanism comprising a balancing spring inserted in an ankle member housing located in an ankle member, a drive gear, a driven gear, an intermediate gear and a gear rod, and a foot part comprising a dorsiflexion spring; a lower leg connecting a knee joint and a foot part to each other, in which a weight-receiving member is located; and a swing storage mechanism connected to the foot part by a second housing of the connection tube and a gear rod pin, and to the knee joint by a first housing of the connection tube and a first housing of the knee joint; and a weight-receiving mechanism comprising a weight-receiving member and a compression arm and a lock fork for activating and deactivating the weight-receiving member.

A prosthesis having a prosthetic foot with a forefoot area and a heel area, a prosthetic lower leg, and a prosthetic foot adapter for arranging the prosthetic foot on the prosthetic lower leg. The prosthetic foot adapter includes an upper part for fixing it to the prosthetic lower leg such that it is torque-proof in relation to a sagittal plane, a lower part for fixing it to the prosthetic foot such that it is torque-proof in relation to a sagittal plane, and a resistance element. The upper part can be swivelled on the lower part about a swivel axis against a restoring force exerted by the restoring element, the swivel axis extending from the heel area to the forefoot area.

Knee orthoses or prostheses can be used to automatically, when appropriate, initiate a stand-up sequence based on the position of a person's knee with respect to the person's ankle while the person is in a seated position. When the knee is moved to a position that is forward of the ankle, at least one actuator of the orthosis or prosthesis is actuated to help raise the person from the seated position to a standing position.
