Upper limb shell
The shell of the upper limb is made of an openwork form of two anatomically formed ABS elements connected with an elbow hinge. Rotary buckles are attached to the shell to enable the fitting of the circumferential straps on the limb. It is also equipped with metal elements with adjustable screw that is used to maintain the correct position of the upper limb. Velcro fasteners have been glued on the inside of the shells, which enable attaching to the shells the soft 3D relief pads.
