  • Patent number: 11963892
    Abstract: A prosthesis or orthosis for a joint, such as an ankle, which includes a first body, a second body, and an articulated joint between the first and second bodies, the articulated joint allowing the rotation of the first and second bodies with respect to one another around a joint rotation axis. It further includes a locking mechanism configured to selectively lock the rotation between the first and second bodies in one direction, when it is in a locked configuration, and a transmission mechanism such that a rotation of the joint rotation axis generates a movement of a lockable part of the locking mechanism. The axis of the movement of the lockable part is shifted relative to the joint rotation axis and the transmission mechanism includes a reducer configured to reduce effort to lock the rotation of the first body with respect to the second body.
