    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 triaxial accelerometers and ballast.
    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.
    2.3.5. The neck is mounted on the neck-bracket, shown as part No. 3 in figure 1 of this annex.
    2.3.6. The angle between the two faces of the neck-bracket is 25 degrees. Because the shoulder block is inclined 5 degrees backwards, the resulting angle between the neck and torso is 20 degrees.
    2.4. Shoulder
    2.4.1. The shoulder is shown as part No. 4 in figure 1 of this annex.
    2.4.2. The shoulder consists of a shoulder block, two clavicles and a shoulder cap.
    2.4.3. The shoulder block (part No. 4a) consists of an aluminium spacer block, an aluminium plate on top and an aluminium plate on the bottom of the spacer block.
    2.4.4. The clavicles (part No. 4b) are made of polypropylene. The clavicles are held back in their neutral position by two elastic cords (part No. 4c) which are clamped to the rear of the shoulder block.  The outer edge of both clavicles accommodates a design allowing for standard arm positions.
    2.4.5. The shoulder cap (part No. 4d) 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. 5 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. 5a) is made of steel. On the rear surface a lead-filled plastic back plate is mounted (part No. 5b).
    2.5.4. The top surface of the thoracic spine box is inclined 5 degrees backwards.
    2.5.5. A rib module (part No. 5c) consists of a steel rib covered by a flesh-simulating polyurethane foam (part No. 5d), a piston-cylinder assembly (part No. 5e) linking the rib and spine box together, a hydraulic damper (part No. 5f) and a stiff damper spring (part No. 5g)
    2.5.6. In the piston-cylinder assembly is a tuning spring (part No. 5h).
    2.5.7. A displacement transducer (part No. 5i) can be mounted on the front face of
