Definitions

  • the present invention relates to a device for sitting, such as a seat, an armchair, a chair, a bench.
  • the essential object of this device is to make it possible to ensure the best possible grip of the spine of a user, and therefore to reduce back pain by sitting in an orthorachism of the spine.
  • This object is achieved due, on the one hand, to the specific structure of the seat and, on the other hand, to the multiple possibilities of adjusting the seat and the backrest.
  • the posterior curve pushes back the column in lordosis without avoiding the specific supports. If the user tries to reach the file with the sacrum, it accentuates the lordosis.
  • the supports of the body being made by the ischial tuberosities on the horizontal part of the seat and by a point of the dorsal column on the vertical part, the lumbar column does not have direct support.
  • Document FR-A-2,072,977 proposes a tilting chair comprising a part forming a seat, a back fixedly connected to the latter and provided with a part forming a head restraint as well as a tubular upright carrying the seat and the back , a person seated in the chair being able to lean back to tilt the seat and the backrest around a horizontal axis placed in the tubular upright, characterized in that a control device capable of being actuated by the tilting movement of the seat part makes it possible to pivot on the one hand a front part, provided on the front side of the seat part, relative to this part about a horizontal axis disposed on the latter and on the other hand, to the by means of an intermediate member capable of being put into action and out of action, the part forming a headrest relative to the backrest around a second horizontal axis disposed on the latter.
  • This document is a tilting chair whose backrest can be tilted so that the spine is applied to it by the weight of the body.
  • the part forming the seat is in a single part, including a single plane.
  • the front part is only used for the legs.
  • the seat / backrest angle is fixed at 90 °.
  • Document FR-A-2,651,657 of the Applicant relates to a seat which is formed by a frame which forms a support for the seat part, feet, and a vertical stem which forms the support for the folder. Hanging from this vertical bracket is the backrest which is articulated at its lower end or base with the seat part.
  • the seat part consists of two seat planes hinged together and the support plane in counterpente is articulated, also, at the base of the hanging file.
  • the first support plane which is substantially horizontal is slidably mounted in a slide on the support formed by the chassis; a fixing means makes it possible to block it in the desired position.
  • the main object of the present invention is to propose a seat comprising two planes and a backrest, the respective positions of which can be modified independently, in order to adapt to the morphology of any user.
  • the backrest is adjustable in depth so that the horizontal plane of the seat is always located under the femurs of the user, while the counter-plan is adjustable angularly depending on the position of the ischial tuberosities.
  • the present invention relates to a device, intended to allow a person to sit down, such as a seat, an armchair, a chair or a bench, of the type which comprises a backrest and a seat made up of two planes of support forming, between them, an obtuse angle ⁇ downwards, the first plane of the seat being in a substantially horizontal position and the second plane of the seat being inclined in a slope against the backrest with which it cooperates, the backrest forming an acute angle ⁇ with respect to the vertical;
  • the first plane of the seat is intended to receive the femurs of a user, the second plane to receive the ischia, the first plane being of a length less than the second plane, characterized in that it comprises means of depth adjustment of the backrest position by relative to the seat and means for angular adjustment of the second plane of the seat relative to the first plane of said seat, which allows the tilting of the pelvis of the user of the device, so as to place the spine in position orthorachism by adjusting the angles
  • the angular adjustment of the second plane of the seat relative to the foreground of said seat and / or the depth adjustment of the backrest and / or the angular adjustment of said backrest is ensured, for each adjustment, by at at least one adjustment screw, the free end of which is in abutment or secured, while remaining mobile in rotation about its longitudinal axis, to the element to be adjusted, and the threaded body of which cooperates with a tapped fixed point on the chassis of the device .
  • the angular adjustment of the second plane of the seat relative to the first plane of said seat and / or the depth adjustment of the backrest and / or the angular adjustment of said backrest is ensured, for each adjustment, by at least one link, one end of which is articulated on the element to be adjusted and the other end of which is movable in a fixed window of the chassis of the device, the assembly being locked in position by a clamping means.
  • the angular adjustment of the second plane of the seat relative to the foreground of said seat and / or the depth adjustment of the backrest and / or the angular adjustment of said backrest is ensured, for each adjustment, by at least one rack link rod articulated by one of its ends on the element to be adjusted, the rack link rod cooperating with a fixed lug, locking in position, carried by the chassis of the device.

  • the depth adjustment of the backrest is ensured by at least two concentric tubes which can slide one inside the other and be locked in position relative to one another by means of locking screw, one of the tubes constituting the chassis of the device, the other tube being integral with the back of said device.
  • the angle ⁇ is substantially 130 degrees (°) and the angle ⁇ is substantially 15 °, which creates an angle ⁇ close to 35 ° (between the second plane of the seat and the backrest) which is specific to each user.
  • Figure 1 shows an overall perspective view of a seat according to the invention.
  • FIG. 2 represents a side view of a first embodiment of the invention.
  • Figure 3 shows a side view of a second embodiment of the invention.
  • Figure 4 shows a side view of a third embodiment of the invention.
  • FIG. 5 represents a side view of a fourth embodiment of the invention.
  • the present invention relates to a device 1 intended to allow a person to sit.
  • This device 1 is represented in FIGS. 1 to 5 by a chair 1.
  • This chair 1 is of the conventional type since it has a back 2 and a seat 3.
  • This seat 3 also has characteristics which are known and clearly visible in FIG. 2.
  • This seat 3 consists of two support planes forming between them an obtuse angle ⁇ downwards.
  • This angle ⁇ corresponds to the inclination of the second plane 5 of the seat 3 with the horizontal.
  • the foreground 4 of the seat 3 has a position which is substantially horizontal. It is intended to receive the femurs of a user.
  • the second plane 5 of the seat 3 is, in turn, inclined against the backrest with respect to the backrest 2. This second plane 5 is intended to receive the user's ischia.
  • the second plane 5 forms with the backrest 2 an acute angle ⁇ .
  • the backrest 2 forms, for its part, an acute angle ⁇ with respect to the vertical.
  • the two angles ⁇ and ⁇ can therefore be adjusted in order to obtain an angle a that is well suited to the morphology of the user.
  • the adjustment of the angles ⁇ and ⁇ also allows the depth adjustment of the second plane 5 relative to the backrest 2, always with the aim of marrying the shapes of the pelvis of said user as well as possible.
  • This figure 2 shows four adjustment possibilities.
  • the backrest 2 can also be adjusted in depth with respect to the seat 3. This adjustment when carried out for the entire backrest 2, is done according to F3. When the adjustment is made, on the contrary, towards the rear, it is carried out according to F4. This adjustment makes it possible to increase or decrease the length of the second plane 5 of the seat 3.
  • This adjustment is made according to F5 when the rear end of the second plane 5 is directed upwards and according to F6 when this rear end is directed downwards.
  • These adjustment means can be angular as regards the position of the backrest 2 relative to the seat 3 but also as regards the second plane 5 of the seat 3 relative to the first plane 4.
  • the adjustment means can also be in depth as regards the position of the backrest 2 relative to the seat 3 but also means for adjusting the height of all of said seat 3 or of all of the chair 1.
