  • the guiding rails of the seat are curved, circular and facing up.
  • the seat can not, in fact, function without the assistance of jacks, which constitute balancing and braking devices.
  • the necessary presence of these cylinders greatly increases the cost of achieving the seat.
  • the object of the present invention is to provide a relaxation seat offering the ability to quickly change the angle of the dihedral formed between elements seat and seat backrest and to keep the seat in position, from a simple and unique movement operated naturally by the user with his body against these elements.
  • the relaxation seat is mainly composed of a frame (not shown) supporting a structure carrier 1 of a flexible support member 2 of the body of the user.
  • the chassis is a usual chassis in the domain, formed from walls assembled together to delimit a overall volume of the seat.
  • the overall volume defined by the chassis is a receiving volume of a moving assembly composed of the supporting structure 1 flexible support body 2.
  • the flexible support member 2 consists of a wall deformable between its base ends 3 and vertex 4, said ends 3 and 4 being equipped with fasteners 5 to the supporting structure 1.
  • the deformability of the flexible support member 2 is in particular deformability of its overall surface in a plane orthogonal to the plane of rest of the seat on the ground.
  • the flexible support member 2 is composed of two rigid frames 6 and 7 freely articulated to each other.
  • the internal space delimited by each of the frames 6 and 7 is dressed by elastic suspension elements deformable, such as springs or slats.
  • These suspension elements are anchored to their side edges on posts of frames 6 and 7.
  • these suspension elements consist of cables 8 arranged in spring, while for the other, the suspension elements are consisting of slats 9.
  • These elements 8 and 9 are described as examples not limiting and can be transposed from one to the other 6 and 7.
  • the flexible support member 2 is composed of slats 10, 11, assembled together by lateral straps 12.
  • the flexible support member 2 may consist of a fabric or similar, or a web with braided straps or composed of transverse slats carried by side straps.
  • the carrier structure 1 generally comprises an element 13 and a back element 14, each consisting of a frame and arranged in the extension of one another so as to delimit a dihedron reception of the body of the user.
  • a back element 14 each consisting of a frame and arranged in the extension of one another so as to delimit a dihedron reception of the body of the user.
  • the seat elements 13 and folder 14 are butted and articulated to each other (axis 15) at their adjacent edges 16 and 17, or hinge edges, to allow a variation of the angle of the dihedron which they delimit jointly.
  • the organ flexible support 2 is intended to be attached to the corresponding free edges of seat elements 13 and backrest 14, respectively base 18 and vertex 19, opposite their articulation edges 16 and 17.

  • the user bearing against the seat element 13 and the file element 14 of the supporting structure 1 via the flexible support member 2, causes a sliding of the seat element 13 and the file element 14 along the corresponding rail, from a concomitant deformation of flexible support organ 2.
  • Maintaining the seat elements 13 and folder 14 according to an orientation predetermined one with respect to the other results from the antagonism of the support that take the sliding members 20, 21, 22 of the seat element 13 and the back member 14 against the corresponding guide rails 23, 24, in according to their respective guide paths along these rails.
  • the angle variation of the dihedral is a continuous value variation between extreme positions of the corresponding seat elements 13 and 14 respectively at positions of extension and withdrawal of the carrier structure 1.
  • the relaxation seat offers the right comfort. This comfort results from the support the body of the user by the flexible organ 2. It also results from the faculty offered by the continuous value variation of the angle of the dihedral delimited between the seat and the seat back. This comfort results still and especially from the simplicity and the ease of the operation to modify the angle of the dihedral, obtained from a simple support of the pelvis and / or back operated by the user against the element corresponding of the carrier structure 1, via the flexible member 2. Such support naturally causes not only variation of angle, but also immobilization in any position of the seat elements 13 and 14 relative to the chassis.
  • the seat frame is equipped with guide rails 23 and 24 sliding members 20, 21 and 22 that comprise the elements of seat 13 and back 14, including a guide rail 23 for the element of backrest 14 and a guide rail 24 for the seat element 13.

  • the guide rail 24, assigned to the seat element 13 is unique and curved up at its ends, while in Figure 5, the rail of 24, assigned to the seat element 13, is composed of two rails of elementary guidance 25 and 26, one rear 26 (close to the articulation of the file with the seat) and the other before 25.
  • the guide rail 23, assigned to the back member 14, is inclined with respect to horizontally, that is to say in relation to the seat resting plane, or by analogy of the chassis, on the ground at an angle D of 45 ° to 55 °, for a length of 220 mm of the guide rail 23.
  • the guide rail 23 is fixed to the frame in an area corresponding to the median area of the file element 14, located between its top edge 19 and its hinge edge 17 to the seat member 13. More particularly, the guide area of the backrest element 14, via the rail of corresponding guidance 23, is located between the user's support zones on the flexible support member 2, and in particular under the support zone of the back and above of the basin support area.
  • the guide rail 23 of the back element 14 provides a back-to-back function. wall ", that is to say it eliminates the recoil of the folder during its tilting. This allows the seat against a wall without interfering with tilting.
  • the length and angle of inclination of the guide rail 23 of the file element 14 are determined by first taking into account constraints of space of the seat, the guide rail 23 in front of, preferably, being mask. In addition, they take into account the length and inclination of the rail of guide 24 of the seat element 13, or even those of the elementary rails of guidance 25 and 26 that compose it. They take into account the position different sliding members 20, 21, 22 that comprise the structure carrier 1, and in particular the position of the sliding member before 21 assigned to the seating element 13.
  • the elementary rails before 25 and rear 26 of guide of the seat element 13 are substantially rectilinear and inclined in opposition compared to the horizontal.
  • the rear elementary rail 26 is in particular inclined downwards, in the direction of front of the seat, in relation to the horizontal, that is to say in relation to the plane of chassis frame at an angle A of the order of 5 ° to 9 °, while the rail elementary front 25 is inclined upwards towards the front of the seat an angle B of the order of 2 ° to 6 °.
  • the front elementary rail 25 is, moreover, preferably bent forward and towards the top of the seat, so as to form at its front end an angle C, of the order of 8 ° to 12 ° with the horizontal. This gives the carrier structure 1 a backward tilting effect concomitantly with its extension.
  • the rear element rail 26 has a length of the order of 310 mm
  • the rail front element 25 has a length of the order of 320 mm
  • the rail 23 of backrest has a length of the order of 220 mm.
  • the rear sliding member 22 of the seat element 13 is located about 40 mm from the axis 15 of articulation of the seat elements 13 and backrest 14, while the sliding member front 21 is located approximately 310 mm behind the base edge 18 of the element 13.

  • the zones 27 and 28 of inflection of the seat elements 13 and 14 are disposed between their free edge 18, 19 and their hinge edge 16, 17.
  • the flexible support member 2 is thus kept at a distance from the structure carrier 1, above the seat element 13 and in front of the element of folder 14, including when the user is installed in the seat.
  • the flexible support member 2 is in practice the actuator, causing the sliding elements of seat 13 and back 14 to slide on the frame. Inflections 27, 28 of the elements 13 and 14 then favor the deformation and mobility of the flexible organ 2, such as its sway and its sagging. Such deformation and mobility allow an accompaniment by the flexible support member 2 of the body movements of the user during the maneuvering of the supporting structure 1, on which it is thus avoided to have to directly support.
  • the lift and movement of the structure carrier 1 on the chassis are obtained in particular by the combination between the articulated arrangement of the supporting structure 1 of the flexible support member 2 and the sliding assembly comprising the three sliding members 20, 21 and 22 forming the support points that takes the carrier structure 1 on the frame.
  • the carrier structure 1 When the carrier structure 1 is in any extension position, the user, to get up, sketch a corresponding movement, in relieving the back forward. Without further action on his part, the structure carrier 1 slides along the chassis to its extreme retracted position.
  • Such a result is particularly obtained from an appropriate combination between the respective positions of the sliding members 20, 21, 22 on the carrier structure 1, the length, shape and position of the guide rails 23, 25, 26 on the frame, and the shape of the seat elements 13 and backrest 14 of the carrier structure 1.
  • Such a combination derives in particular the ease of the sliding of the supporting structure 1 on the chassis in translation and in forward extension, and the automaticity of the fallback movement of the bearing structure 1 caused by the restoring torque exerted by the maintenance in suspension on the frame of the supporting structure 1, during its sliding in fallback position.
  • the position of the sliding member 21 before the seat member 13 determines the opening in maximum extension of the supporting structure 1, in because of his participation in means of putting the structure in abutment 1 against the end of the elementary rail before 25, as well as the degree of tilting of the seat element 13 causing the tilting of the supporting structure 1 and the leverage effect needed to automate the sliding towards the back of the supporting structure 1.
  • the inclination and the length of the rails therefore allow a specific adjustment depending on the type of comfort sought.
  • the feeling of comfort is different depending on the position of the seat, which generates a wealth of use.
  • the flexible support organ 2 is likely to be constituted by other similar embodiments, the qualities of sought structure being to be deformable between its base ends 3 and 4 through which it is attached to the carrier structure 1, in order to transmit to the corresponding edges of the seating elements 13 and folder 14 the tensions at which the flexible support member 2 is subjected under the effect of the support that the user takes against the latter.
  • the seat may comprise accessory means for blocking the structure carrier 1 in any of its positions, to prohibit a spontaneous modification of the angle of the dihedral when the seat is unoccupied. This spontaneous modification is likely to occur under the effect of a support exercised at the top of the seat by an inattentive person when the carrier structure 1 is in the folded position.
  • These blocking means may in particular be constituted by an organ preventing the sliding of the seat element 13 on the chassis, or even by a cooperation between two cooperating interlocking members, respectively supported by the supporting structure 1 and the frame, said cooperation being implemented from a voluntary gesture of the user when leaving the seat.
  • the seat may also include ancillary means of assistance to the sliding operation of the seat elements 13 and folder 14 along the guide rails 23, 24 which are assigned to them.
  • An electric cylinder can, for example, example, be interposed between the chassis on which it is fixed, for example by clipping, and a support beam formed on the seat element 13.
