A remote-load-bearing section for a first swivel arm (FSA) (22) forms a limb for a non-symmetrical four-bar mechanism with its limb opposite the FSA represented by a vertical peg (28), on which upper (34) and lower (36) articulated limbs with an on-axis clearance from each other each swivel on bearings around the peg's axis and two parallel horizontal axes. |
