Abstract
Abstract The invention relates to a device for adjusting and fixing the back (8) and the seat (9) of an arm-chair, deck-chair or the like to a supporting structure (1) allowing said back and seat to continuously reach different positions of reciprocal inclination ranging between two end inclinations respectively corresponding to a minimum and a maximum inciination. in order to allow the user to vary the inclination between seat (9) and back (8) without removing his bust from the supporting surface and with a very little effort, the back (8) is supported and fixed in a rotary way around a horizontal axis (12) fixed with respect to said supporting structure (1), the seat (9) is fixed to the back (8) by means of hinges (10) and to the structure (1) by means of constraints (6) which support the seat and allow the same to perform predetermined translation and/or rotation movements compatible with the presence of said hinges and without solutions of continuity between said end inclinations, and at least one of said constraints is braked.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
1) A device for adjusting and fixing the back (8) and the seat (9) of an arm-chair, deck-chair or the like to a supporting structure (1), allowing the back and seat to reach different positions of mutual inclination between two end inclinations respectively corresponding to a minimum inclination and a maximum inclination, characterized in that said back (8) is supported and fixed in a rotary way around a horizontal axis (12) fixed with respect to said supporting structure (1), in that said seat (9) is fixed to the back (8) by means of hinges (10) and to the structure (1) by means of constraints (6) which support the seat (9) and allow it to perform predetermined translation and/or rotation movements, compatible with the constraints of said hinges (10, 12) and without solutions of continuity between said two end inclinations, and in that at least one of said constraints (6, 10, 12) is braked.
Claim 2
Dependent Claim
153 words
1) A device for adjusting and fixing the back (8) and the seat (9) of an arm-chair, deck-chair or the like to a supporting structure (1), allowing the back and seat to reach different positions of mutual inclination between two end inclinations respectively corresponding to a minimum inclination and a maximum inclination, characterized in that said back (8) is supported and fixed in a rotary way around a horizontal axis (12) fixed with respect to said supporting structure (1), in that said seat (9) is fixed to the back (8) by means of hinges (10) and to the structure (1) by means of constraints (6) which support the seat (9) and allow it to perform predetermined translation and/or rotation movements, compatible with the constraints of said hinges (10, 12) and without solutions of continuity between said two end inclinations, and in that at least one of said constraints (6, 10, 12) is braked.
Claim 3
Dependent Claim
44 words
2) A device according to claim 1, wherein said rotation axis (12) of the back (8) with respect to the framework (1) is placed at a distance from the articulation point between the seat and the back substantially corresponding to the user's barycenter (B).
Claim 4
Dependent Claim
43 words
3) A device according to claim 1 or 2, wherein said seat constraints (6) are such as to allow the seat to perform movements of rotation around a horizontal axis, said axis being able to slide londigudinally with respect to the supporting structure.
Claim 5
Dependent Claim
54 words
4) A device according to claim 3, wherein the constraints (6) between the seat and the supporting structure are supports (24) sliding along longitudinal guides (23) having an arc-of-circumference development, parallel to the seat direction of movement, the supports and guides being respectively fixed to the seat and to the structure, or vice versa.
Claim 6
Dependent Claim
37 words
5) A device according to claim 4, wherein said supports are costituted by two small blocks (24) each having a longitudinal notch (25) each notch being capable of receiving a guide (23) consisting of a flattened bar.
Claim 7
Dependent Claim
66 words
6) A device according to claim 1 or 2, wherein the constraints (6) between the seat and the supporting structure consist of rectilinear guides (14) parallel to the seat direction of translation and fixed in a sliding way to small blocks (13) freely oscillating around horizontal axes, said small blocks and said guides being respectively fixed to the structure and the seat sides, or vice versa.
Claim 8
Dependent Claim
70 words
7) A device according to clamim 6, wherein said guide (14) has a X-shaped section an upper gap (19) of which houses a tube (7) constituting the seat framework, while the guide lower arms (20) are spread apart and are coupled to a seat (21) formed in a small block (17), inserted on a pivot (18), so as to prevent the small block from moving away from said guide (14).
Claim 9
Dependent Claim
70 words
7) A device according to clamim 6, wherein said guide (14) has a X-shaped section an upper gap (19) of which houses a tube (7) constituting the seat framework, while the guide lower arms (20) are spread apart and are coupled to a seat (21) formed in a small block (17), inserted on a pivot (18), so as to prevent the small block from moving away from said guide (14).
Claim 10
Dependent Claim
39 words
8) A device according to claim 1 or 2, wherein said hinges connecting the seat (9) and the back (8) are in the form of resilient sleeves (26) which can bend around an axis of rotation located outside themselves.
Claim 11
Dependent Claim
42 words
9) A device according to claim 8, wherein said sleeves (26) are formed by elements of molded rubber housing a steel cable (27) said cable being fixed, at each end and by means of rivets, respectively to the seat and the back.
Claim 12
Dependent Claim
31 words
10) A device according to claim 8 or 9, wherein said seat and back comprise metal tubular framewordk connected by such sleeves (26) and sustaining a single piece of cloth (11).
