Patent ID: 7774996

Claim:
A device for damping the relative movement of a first structural member in relation to a second structural member, the first structural member being rotationally joined to at least two elements of a first group of elements, and the second structural member being rotationally joined to at least two elements of a second group of elements, wherein each of the at least four elements is joined to the structural members, respectively, by means of a joint fixating a first end of the element relatively to the structural member while allowing rotation of the element, wherein a second end of each of the elements of the first group of elements are individually joined to a second end of an element of the second group of elements in a rotational joint, so as to form at least six rotational joints for damping relative movement between the elements of the first group of elements and the elements of the second group of elements and thus for damping the movement of the first structural member in relation to the second structural member, and wherein at least one of said rotational joints comprises a damping member, the damping member comprising a piece of friction material so that relative rotation of the elements is dampened by friction.
