Abstract:
A wrist device for a prosthetic limb is provided. The device (1) comprises a base member (3) connectable to the wearer of the device, and a support member (13) connectable to the limb. The support member (13) is pivotably connected to the base member (3) such that the support member can pivot about a pivot axis (A) relative to the base member. A damping mechanism is located between the base (3) member and the support member (5). The damping mechanism comprises a pinion (47) connected to the support member (5) and rotatable about the pivot axis (A) relative to the base member (3). A rack (35) is engaged with the pinion (47) such that rotational motion of the pinion causes a linear motion of the rack, and at least one biasing member (41) extends between the base member (3) and the rack. The biasing member (41) biases the rack (35) and support member (13) into a neutral position. A prosthetic limb incorporating the wrist device is also provided.
