<p>The spring unit has a base plate (46), a set of support plates (12-18) distributedly arranged around a spring axis (I) and separated at a distance from the base plate towards the spring axis. A set of spring arms (30-36) connects the support plates with the base plate, where the spring arms are rotated around an axis that is parallel to the spring axis. The spring arms divert tangentially from the base plate.</p> |
