Abstract
Abstract The invention relates to a variable seating arrangement with a plurality of seating elements which are supported by at least two approximately horizontal support elements (1, 1') the adjacent ends (1a, 1'a) of which are connected to one another in a common connecting column (4) and are pivotable relative to one another about a vertical shaft (6). In this way an extremely large number of arrangements and groupings of the seating elements relative to one another are possible.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
In a variable seating arrangement having a plurality of seating elements, the improvement comprising at least two horizontally extending linear support elements, at least one seating element attached along the upper surface of each of said support elements fixed thereto against torsion about the longitudinal axis thereof and forming a seat assembly, a connecting column at each end of each support element including a common connecting column between adjoining seat assemblies of a common seating arrangement, and a connecting joint between each end of each such support element and the connecting columns at corresponding ends thereof cooperating coaxially to permit relative pivoting movement of each support element about the vertical axis of the connecting column while restricting torsional movement between each such support element and the connecting column, each horizontally extending support element maintaining the respective connecting column in a vertical position, whereby each multiple seat assembly is carried solely by a single support element and the adjoining connecting columns at its ends, and seat assemblies sharing a common connecting column are relatively pivotable thereabout for variable arrangements as desired.
Claim 2
Dependent Claim

In a variable seating arrangement having a plurality of seating elements, the improvement comprising at least two horizontally extending linear support elements, at least one seating element attached along the upper surface of each of said support elements fixed thereto against torsion about the longitudinal axis thereof and forming a seat assembly, a connecting column at each end of each support element including a common connecting column between adjoining seat assemblies of a common seating arrangement, and a connecting joint between each end of each such support element and the connecting columns at corresponding ends thereof cooperating coaxially to permit relative pivoting movement of each support element about the vertical axis of the connecting column while restricting torsional movement between each such support element and the connecting column, each horizontally extending support element maintaining the respective connecting column in a vertical position, whereby each multiple seat assembly is carried solely by a single support element and the adjoining connecting columns at its ends, and seat assemblies sharing a common connecting column are relatively pivotable thereabout for variable arrangements as desired.
Claim 3
Dependent Claim
52 words
Seating arrangement as claimed in claim 1, characterised in that the connecting column includes a base, a vertical supporting tube and an upper connecting cone, and between said upper connecting cone and the supporting tube, the connecting joint and a vertical shaft constructed in the form of a connecting bolt are arranged.
Claim 4
Dependent Claim
47 words
Seating arrangement as claimed in claim 2, characterised in that the connecting joint is formed by two interengaging joint parts which are each provided on one end of a support element and by the connecting bolt which connects the upper connecting cone to the vertical supporting tube.
Claim 5
Dependent Claim
34 words
Seating arrangement as claimed in claim 3, characterised in that the interengaging joint parts are formed by two similar castings which are fixed on alternate sides of the appertaining end of the support element.
Claim 6
Dependent Claim
37 words
Seating arrangement as claimed in claim 1, characterised in that each support element essentially consists of a tube which is approximately flat-oval in cross-section and aligned on its edge with a joint part fixed on each end.
Claim 7
Dependent Claim
29 words
Seating arrangement as claimed in claim 1, characterised in that the seating element fixed on each support element are constructed in the form of individual or linked chair elements.
