Abstract
Abstract A relaxation device for furniture, particularly for an armchair of relaxing chair, includes body support flats (11, 12, 13; 101; 201) which are each formed of interconnected elongated support members (3) extending parallel to each other and transversally to a longitudinal axis of the device (Z), a frame (2) and means (23, 43) for coupling the above support flats (11, 12, 13; 101, 201) to the frame (2), characterized in that each set of elongated support members (3) is mounted by means of a multiple action suspension system (S1, S2) which is formed of a first stage suspension unit wherein each pair of adjacent elongated support members (3', 3") is externally coupled by means of primary intermediate suspension parts (31), and at least one additional second stage suspension unit wherein each pair of adjacent primary intermediate suspension parts (31', 31") is externally coupled by secondary suspension parts (33; 32', 32") which are directly (23) or indirectly (23, 33, 24) connected to the frame (2), so that the elongated support members (3) are mutually movable in two modes and can move from an unloaded state (A) to a loaded state (B) with the superimposed undulatory motion of said members (3).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
A body comfort device for furniture, in particular for seat or relaxing furniture, comprising; a frame having opposite sides, body support flats substantially in a same plane, each of said body support flats having at least one pair of elongate supporting elements on opposite sides of said body support flats, said elongate supporting elements being arranged parallel to each other and substantially perpendicularly oriented to longitudinal inner sides of said frame, N sets of intermediate suspension elements, each intermediate suspension element of a first set (I=1) of said set being connected by a first intermediate articulation connection to at least two elongate supporting elements, each intermediate suspension element of an N th set of said sets (I=N) connecting at least two intermediate suspension elements of an (N-1) th set to said frame by a second articulation connection, each intermediate suspension element of an i th set (1<i<N) connecting at least two intermediate suspension elements of an (I-1) th set to an intermediate suspension element of an (I+1) th set.
Claim 2
Dependent Claim
169 words
A body comfort device for furniture, in particular for seat or relaxing furniture, comprising; a frame having opposite sides, body support flats substantially in a same plane, each of said body support flats having at least one pair of elongate supporting elements on opposite sides of said body support flats, said elongate supporting elements being arranged parallel to each other and substantially perpendicularly oriented to longitudinal inner sides of said frame, N sets of intermediate suspension elements, each intermediate suspension element of a first set (I=1) of said set being connected by a first intermediate articulation connection to at least two elongate supporting elements, each intermediate suspension element of an N th set of said sets (I=N) connecting at least two intermediate suspension elements of an (N-1) th set to said frame by a second articulation connection, each intermediate suspension element of an i th set (1<i<N) connecting at least two intermediate suspension elements of an (I-1) th set to an intermediate suspension element of an (I+1) th set.
Claim 3
Dependent Claim
76 words
A body comfort device according to claim 1, wherein the first intermediate articulation connection articulates the intermediate suspension elements to one another and the elongate supporting elements, said first intermediate articulation connection consists of shafts which are all oriented in the direction of a longitudinal axis of the elongate supporting elements such that the elongate supporting elements are oriented by pivoting on their longitudinal axis when subjected to stress by the load of a user's body.
Claim 4
Dependent Claim
109 words
A body comfort device according to claim 1, further comprising a multiple-action suspension system having a pair of cables intersecting one another and cooperating with rollers, each roller forming a pulley and provided with a peripheral groove for the passage of said cables, and wherein each elongate supporting element is fastened to at least one double wheel, along which said cables intersect, and said rollers are fastened in pairs to said frame 50, that they are arranged alternately with the first rollers in a diamond-shaped configuration, such that said cables extend over the entire length of said body support flats at the same time zigzagging relative to each other.
Claim 5
Dependent Claim
30 words
A body comfort device according to claim 3, wherein said double rollers can rotate individually relative to one another or in a mutually integral manner on a common rotary shaft.
Claim 6
Dependent Claim
60 words
A body comfort device according to claim 3, wherein said elongate supporting elements of each body support flat is tensioned between the two cables, each of the cables acting as a pressure receiver in the event of load on the body support flat, and each other cable acting as a traction element, pulling each corresponding support flat against said frame.
Claim 7
Dependent Claim
25 words
A body comfort device according to claim 3, wherein each cable can be clamped by clamping members to adjust the length of the said cables.
Claim 8
Dependent Claim
25 words
A body comfort device according to claim 1, wherein each body support flat is one-piece including said elongate supporting elements and said intermediate suspension elements.
Claim 9
Dependent Claim
21 words
A body comfort device according to claim 7, wherein said body support flats are produced by injection moulding from synthetic material.
Claim 10
Dependent Claim
43 words
A body comfort device for furniture according to claim 1, wherein said elongate supporting elements and said intermediate suspension elements are formed as a one-piece member, said articulation connections being formed by linking members, thereby enabling an injection moulding of the one-piece member.
Claim 11
Dependent Claim
63 words
A body comfort device for furniture according to claim 1, wherein each said intermediate suspension element of one i th first set (i=1) comprises two T-shaped elements fitting in a central horizontal part of an H-shaped element, forming a second intermediate suspension element (i=2), said N th element (N=3) being formed by a sub-frame to which at least one H-shaped element is connected.
Claim 12
Dependent Claim
28 words
A body comfort device for furniture according to claim 1, wherein said intermediate suspension elements bend and successive sets of intermediates suspension elements are connected by a pivot.
Claim 13
Dependent Claim

A body comfort device for furniture according to claim 1, wherein said articulation connections, are provided for enabling articulation of said intermediate suspension elements with respect to each other and to said elongate supporting elements, each articulation connection being formed by an articulation shaft enabling the elongate supporting element to move by pivoting around its longitudinal axis.
Claim 14
Dependent Claim
30 words
A body comfort device according to claim 1, wherein said articulation connections between said elongate supporting elements are formed by at least one cable passing through said elongate supporting elements.
Claim 15
Dependent Claim
