Between the ends (5,6) of the spring component in the longitudinal direction (7) is at least one tension component (4) with adjustable tension and traction. Along the spring component and between the ends on the load side interconnected chain components (1) are so arranged that at least indirectly they support on one another in the longitudinal direction. They are pivotable relatively to one another around pivot axes (8) which run crossways to the longitudinal direction and crossways to the first cross direction. |
