Abstract:
A device for relative movement of two elements comprising:a first element forming a base element; a second element movable with respect to the first element; at least two link devices coupled between the first and second elements, each of said link devices comprising at least two mutually articulated link units; plural power exerting arrangements provided to impart to the link devices pivoting movements which change a relative position of the elements; a first of the link devices being connected to one element of the first and second elements via a hinge connection so that there are, between said first link device and said one element, at least two degrees of freedom in the form of relative pivotability about two pivot axes forming an angle relative to each other; wherein said first link device is movable relative to another element of the first and second elements with one single degree of freedom; wherein a further link device is connected to said other element of the first and second elements via a hinge connection which provides freedom of movement between said further link device and said other element of the first and second elements including at least two degrees of freedom consisting of pivotability about two different pivot axes.
