Definitions
- the present invention relates to a seat system with an ergonomic and relaxing suspended seat, adjustable, with complete and secure variable inclination, balanced by the sole weight of the body without mechanism or notch.
- Some seat systems allow a variable inclination but allow only partial physical relaxation of the body, not supporting it in its entirety from head to toe or having a rigid non-ergonomic seat.
- Other seat systems have a flexible seat but do not have any adjustment of the length of this seat or of the position of the headrest, being unable to adapt precisely to the different morphologies of the users.
- Certain other seat systems allow a variable inclination but only allow a partial or limited inclination, allowing either only the inclination of the seat back alone, or only a maximum inclination in a semi-extended position, or a tilt simultaneously causing variation and deformation of the shape of the seat base and therefore limited by the friction of the base on the ground.
- the system according to the present invention supplements and improves on the existing variable-tilt seat systems as follows: 1) Suspended, ergonomic and relaxing seating system: By the following 2 methods, the system according to the present invention in fact allows ergonomic support of the entire body of the user, causing muscle and circulatory relaxation and relaxation real whatever the inclination adopted:
- the 1st process consists of a flexible seat, adapting ergonomically to the shape of the user's body, seat suspended at the 2 ends of the seat carriage and supported at the knees, associated with a support - removable and adjustable head and an integrated footrest. The entire body of the user is thus permanently supported from head to toe in all the positions permitted by the seat.
- This flexible suspended seat distributes and supports
- the system according to the present invention allows an adjustment of the shape of the seat to adjust it to the morphology of its user.
- 2-a) The first process allows the shortening or lengthening of this seat depending on the size of the user. This process is based on a system for adjusting the front or rear of the attachment bar of the seat in its lower part by points
- the system according to the present invention consists of a seat (see method 1), suspended on a tilting and deformable seat carriage longitudinally and reversibly on a fixed, rigid and non-deformable base, independently of this base and without modification thereof. , while having a system of safety stops fixed on the base, controlling the rear rocker as far as it will go.
- the system according to the present invention allows a variable, complete and secure inclination of the seat, allowing the user to modify the inclination of the seat from the sitting position to the lying position, with all the positions possible intermediates, without risk of overturning in maximum rear position.
- the 1st process is based on the constitution of the base of the seat carriage in a deformable centered semi-parallelepiped consisting of 2 semi-quadrilaterals joined together, equilateral deformable and symmetrical in 2 parallel planes focusing the structure seat, allowing the free rotation of the seat / seat trolley assembly suspended on the stable and rigid base:
- This deformable semi-parallelepiped is defined by the meeting of the 3 rigid parts constituting the seat carriage, fixed and pivoting between them and on the base, this meeting forming 2 symmetrical equilateral semi-quadrilaterals in the 2 parallel planes, their equilaterality being defined by the equal distance between the 4 vertex points of the 2 quadrilaterals one by one.
- the parallelepiped thus formed is deformable longitudinally and symmetrically by pivot on the stable base around its 2 fixed upper axes and around its 2 lower axes, these 4 axes being parallel and perpendicular to the 2 parallel planes axing the structure.
- the 2 nd process is constituted by the interaction by rotation of the previous parallelepiped on the rest of the structure of the seat carriage (backrest and footrest), of which it is a constituent part.
- the seat carriage fixed and swiveling freely on the stable and non-deformable base, supports and supports the seat, itself supporting the user. Any deformation and elongation of the seat carriage causes deformation and elongation of the seat and therefore the variation in inclination of the position of the user.
- the system according to the present invention allows a control and a balance of the inclination of the seat structure / seat trolley by the sole weight of the body of the user, without mechanism or notch.
- This system is enabled by a process of alignment and interaction on the same axis of the body weight of the user in the seat cushion and the center of balance of the seat carriage.
- This alignment process connects: - the point of balance of the user's body weight at the center of the flexible seat suspended and fixed at its 2 ends and supported and sliding freely at the knees (see process 1), on 3 constituent bars of the seat carriage itself fixed and swiveling on a stable and rigid base (see method 3), the whole of the seat carriage being balanced on: - the centering point of the deformable parallelepiped previously defined ( see process 3), located at the intersection of the axes joining its opposite vertices and constituting the point of balance of the seat carriage.
- the two points above superimposed define an axis connecting the point of balance of the body weight of the user to that of the trolley.
- FIG. 1 shows the system of the present invention in its starting seating configuration
- FIG. 10 - Figure 2 shows the system of the present invention in its variation of maximum inclination Description of the system:
- this system has 3 main components: 1. a flexible seat (A), equipped with a removable headrest (E) fixed by fasteners, adjustable lateral c (L1, L2) (laces, Velcro, presses or other method of fastening).
- L1, L2 adjustable lateral c
- This seat is fixed and / or suspended on the seat carriage: - at its 2 ends on 2 bars (T2, T5), so as to slide freely in rotation (gussets or other method of fixing), T5 being fixed and T2 removable to allow attachment and adjustment of the seat length 0 - at the knees on a fixed bar (Tl), so as to slide freely - at the ankles on a fixed bar (T3), so as to slide freely 2.
- a seat trolley made up of 3 rigid parts, fixed and swiveling between them (B1, B2, B3), jointly constituting the back and seat frames, and organized as follows:
- 25 - Bl a rigid semi-parallelogram with 3 U-shaped sides, supporting the seat on its upper side (T5), fixed and pivoting at its 2 lower ends by 2 symmetrical rotation points (4), fitted with anti-friction seals , along an axis (X4), on 2 planes parallel to each other perpendicular to this axis, on: - B2: a rigid parallelogram with 4 sides, forming an integrated footrest (R) on its front side, equipped with the 2 transverse bars allowing the sliding (T3) and the fixing and the adjustment in length (T2) of the seat, B2 being fixed and pivoting in 2 symmetrical points of rotation (3), equipped with anti-friction joints, along an axis (X3) parallel to X4, on the same 2 previous parallel planes on: - B3: a rigid semi-parallelogram with 3 sides, its upper side being offset at its 2 ends towards the inside of the parallelogram to form a transverse fixed bar (Tl) supporting the seat at the knees of the seated
- a stable and rigid base resting on the ground, consisting of symmetrical non-deformable elements forming a base and armrests (F), incorporating safety stops (S) controlling the rocking of the seat in the rear position.
- the deformable parallelepiped constituted by P1 / P2, fixed and rotatable on an undeformable base, is balanced in its rotation around its center located in (G '), intersection of the axes joining the opposite vertices of the parallelepiped.
- This center constitutes with the center of equilibrium of the user's body weight (G) an axis parallel to the vertical axes b) a distance from axes XI and X2 to the ground greater than the height of the 2 quadrilaterals P1 / P2 (points 1 - 3 and 2 - 4), to allow the suspension of the seat carriage on the base allowing the free tilting of the carriage around G without friction on the ground.
- This seat system with ergonomic and relaxing suspended seat, adjustable, with complete and secure variable inclination balanced by the body weight can be used: in all the usual materials of the furniture sector (metal, wood, composite materials or others) and in various structural forms (rounded, angular, etc.), therefore not being subject to fashion phenomena - for all economic sectors requiring practical and comfortable furniture (thalassotherapy, hotel equipment, decoration, garden center, ...
- the footrest (R) integrated in the seat carriage naturally follows the lengthening or straightening of the carriage, supporting the legs in all positions.
- the simple transfer of his body weight by the user therefore causes the controlled dynamic tilting of the entire seat seating system, lengthening or straightening, partially or completely, the seat according to the desired position. All the positions obtained are stable and require no effort to be maintained.
