<p>The apparatus comprises an equipment frame (1), a seat (2) provided with a back rest (3), and holding means (4) for holding a person's body substantially immobile in position relative to the back rest. A link rod (5) is pivoted by its first end (6) on the equipment frame via a first joint (7) permitting a turning motion about a swing axis (8) perpendicular to the vertical middle plane of the seat. A head rest (9) is functionally connected to the link rod (5) so that the link rod participates in turning the head rest during an exercise movement while the person's head is leaning against the head rest. A resistance means (10) generates a force opposing the exercise movement. The apparatus comprises adjusting elements (11) for adjustment of the position of the seat in relation to the equipment frame (1). The head rest (9) is substantially fitted to receive the upper part of the person's neck. The apparatus comprises a multi-joint angular linkage mechanism (12), of which the link rod (5) constitutes a part. The multi-joint angular linkage mechanism (12) is connected to the head rest (9) so as to cause it to move during an exercise movement along a curved path that substantially coincides with the natural path of the neck.</p> |
