is shown as part No. 1 in Figure 1 of this annex.

              2.2.2. The head consists of an aluminium shell covered by a pliable vinyl skin. The interior of the shell is a cavity accommodating tri-axial accelerometers and ballast.

              2.2.3. At the head-neck interface a load cell replacement is built in. This part can be replaced with an upper neck load-cell.

              2.3. Neck

              2.3.1. The neck is shown as part No. 2 in Figure 1 of this annex.

              2.3.2. The neck consists of a head-neck interface piece, a neck-thorax interface piece and a central section that links the two interfaces to one another.

              2.3.3. The head-neck interface piece (part No. 2a) and the neck-thorax interface piece (part No. 2c) both consist of two aluminium disks linked together by means of a half spherical screw and eight rubber buffers.

              2.3.4. The cylindrical central section (part No. 2b) is made of rubber. At both sides an aluminium disk of the interface pieces is moulded in the rubber part.

              2.3.5. The neck is mounted on the neck-bracket, shown as part No. 2d in Figure 1 of this annex. This bracket can optionally be replaced with a lower neck load-cell.

              2.3.6. The angle between the two faces of the neck-bracket is 25°. Because the shoulder block is inclined 5° backwards, the resulting angle between the neck and torso is 20°.

              2.4. Shoulder

              2.4.1. The shoulder is shown as part No. 3 in Figure 1 of this annex.

              2.4.2. The shoulder consists of a shoulder box, two clavicles and a shoulder foam cap.

              2.4.3. The shoulder block (part No. 3a) consists of an aluminium spacer block, an aluminium plate on top and an aluminium plate on the bottom of the spacer block. Both plates are covered with a polytetrafluoretheen (PTFE)-coating.

              2.4.4. The clavicles (part No. 3b), made of cast polyurethane (PU)-resin, are designed to evolve over the spacer block. The clavicles are held back in their neutral position by two elastic cords (part No. 3c) which are clamped to the rear of the shoulder box. The outer edge of both clavicles accommodates a design allowing for standard arm positions.

              2.4.5. The shoulder cap (part No. 3d) is made of low-density polyurethane foam and is attached to the shoulder block.

              2.5. Thorax

              2.5.1. The thorax is shown as part No. 4 in Figure l of this annex.

              2.5.2. The thorax consists of a rigid thoracic spine box and three identical rib modules.

              2.5.3. The thoracic spine box (part No. 4a) is made of steel. On the rear surface a steel spacer and curved, polyurethane (PU)-resin, back plate is mounted (part No. 4b).

              2.5.4. The top surface of the thoracic spine box is inclined 5° backwards.

              2.5.5.
