Abstract
Abstract A frame has transversely spaced frame portions which are suitably connected with one another. Elongated flexible support webs are carried by the frame extending in parallelism with one another and with the frame portions. Flexible tubular sections of synthetic plastic material extend transversely of the frame portions from one to the other, being located in parallelism with each other and arrayed lengthwise of the frame portions. Sheetmaterial strips are each connected with the end portions of the tubular members located adjacent the respective frame portions; these sheet material strips extend lengthwise of the respective frame portions and are secured to the same.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
163 words
In a piece of furniture, particularly in a folding chair or lounge, in combination, frame means including a first pair of elongated transversely spaced frame portions and a second pair of transversely extending frame portions connecting said first pair of frame portions to each other; a plurality of elongated flexible discrete first members extending substantially parallel to said first frame portions; a plurality of elongated flexible discrete second members extending substantially parallel to said second pair of frame portions and overlying said first members fixedly connected to at least some of the same, and having spaced end portions respectively inwardly proximal to said first frame portions; a pair of sheet material strips fast with and extending lengthwise of said first frame portions, each of said strips having two superimposed lateral longitudinal margins connected in stress-transmitting relationship with the respectively adjacent end portions of said second members; and means connecting said first members in stress-transmitting relationship to the respective second pair of frame portions.
Claim 2
Dependent Claim
163 words
In a piece of furniture, particularly in a folding chair or lounge, in combination, frame means including a first pair of elongated transversely spaced frame portions and a second pair of transversely extending frame portions connecting said first pair of frame portions to each other; a plurality of elongated flexible discrete first members extending substantially parallel to said first frame portions; a plurality of elongated flexible discrete second members extending substantially parallel to said second pair of frame portions and overlying said first members fixedly connected to at least some of the same, and having spaced end portions respectively inwardly proximal to said first frame portions; a pair of sheet material strips fast with and extending lengthwise of said first frame portions, each of said strips having two superimposed lateral longitudinal margins connected in stress-transmitting relationship with the respectively adjacent end portions of said second members; and means connecting said first members in stress-transmitting relationship to the respective second pair of frame portions.
Claim 3
Dependent Claim
40 words
In an article of furniture as defined in claim 1, wherein said means connecting said first members in stress-transmitting relationship comprises envelope-like cover portions which can be slipped over the frame means at the regions of its transversely extending portions.
Claim 4
Dependent Claim
18 words
In a piece of furniture as defined in claim 1, wherein said frame portions are of tubular cross-section.
Claim 5
Dependent Claim
20 words
In a piece of furniture as defined in claim 1, wherein said second members are sleeve-shaped and of annular cross-section.
Claim 6
Dependent Claim

In a piece of furniture as defined in claim 1; and further comprising a plurality of welds connecting said first members with said second members, and connecting said end portions with the respective strips.
Claim 9
Dependent Claim
53 words
In a piece of furniture as defined in claim 1, said strips and said second members being composed of a weldable synthetic plastic material, and wherein said end portions are each locaTed between said lateral margins of the respectively associated strip; and further comprising welds connecting said end portions with the respective margins.
Claim 10
Dependent Claim
19 words
In a piece of furniture as defined in claim 1, said strips each embracing the respectively associated frame portion.
Claim 11
Dependent Claim
65 words
In a piece of furniture as defined in claim 1, said strips each being bi-folded transversely to their respective longitudinal extension, and each having a longitudinal fold extending along the associated superposed lateral margins; at least a pair of elongated stiffening elements each received in and extending lengthwise of the respective fold; and securing means securing the respective stiffening element to the associated frame portion.
Claim 12
Dependent Claim
27 words
In a piece of furniture as defined in claim 10, said securing means comprising screws fast with said stiffening elements and threaded into the associated frame portion.
Claim 13
Dependent Claim
28 words
In a piece of furniture as defined in claim 10, said stiffening elements having a length at least substantially the same as the length of the associated strips.
Claim 14
Dependent Claim
15 words
In a piece of furniture as defined in claim 10, said stiffening elements being rod-shaped.
Claim 15
Dependent Claim
15 words
In a piece of furniture as defined in claim 10, said stiffening elements being strip-shaped.
Claim 16
Dependent Claim
30 words
