1. A force-balancing support for a movable arm, which movable arm is attached to a base and rotatable around a movable rotation point, movable relative to the base, the support comprising:
an arm attachment connectable to the movable arm;
a base attachment at a distance from the arm attachment, for attaching the support to the base;
the arm attachment being at least rotatable relative to the base attachment, around a center of rotation of which a position is movable relative to the base attachment;
a cantilever spring mechanism for at least partially transferring a force exerted on the arm attachment by the movable arm, when coupled thereto, via the base attachment to the base,
the cantilever spring mechanism comprising:
a fixed, base-side, cantilever end attached to the base attachment of which a position is fixated relative to the base attachment, and
a free, arm-side, cantilever end which is movable with respect to the base attachment at least by suitable flexing of the cantilever spring mechanism and by which the arm attachment is held suspended with respect to the base attachment,
the position of the center of rotation being at least partially dependent on a position of the free cantilever end which in turn is at least partially determined by a position of the arm attachment, wherein the force balancing support comprises an arm assembly formed by the arm attachment and a lever arm which extends away from the arm attachment from the center of rotation to a lever end, which arm assembly comprises at least two pivots, of which one pivot is the center of rotation which is used to connect to the free cantilever end and another pivot is via a member attached to the base attachment.
