Definitions
- the present invention relates to a seat comprising a foot part, a seat part and a back part, arranged so as to allow a sitting position in which the pelvis is straight, the back part being designed to promote this position and comprising for this purpose a support device giving posterior support to all the bones of the pelvis.
- a seat according to the invention makes safe and easy the prolonged maintenance of the sitting position by effectively stabilizing the pelvis, thus allowing a correct arrangement of the trunk on its base. Such a seat helps to reduce fatigue and pain in the trunk when seated.
- this support at the sacroiliac joint is therefore carried out on all the pelvic bones, that is to say simultaneously on the posterior edge of the two iliac bones (in point 3 of Figures 1, 2 and 3 , below EIPS, point 6) and on the sacrum (at point 4 in Figures 2 and 3, above the most posterior point of the posterior surface of the sacrum, point 7 in Figures 1, 2 and 3).
- the advantage of this support therefore lies mainly in its effectiveness in opposing the retroversion of the pelvis in a seated position while avoiding the risks mentioned above, thus contributing optimally to stabilize the pelvis on which the spine and the trunk can therefore lean with ease.
- This posterior support thus contributes to avoiding the fatigue linked to a prolonged sitting position by reducing as much as possible the tensions necessary to maintain the trunk in a correct position.
- Such a type of support is made possible by the use of a seat provided, according to the invention, with a posterior support device of suitable shape and consistency, placed on the front face of the backrest or secured to amounts which support it.
- This device is located at a height relative to the seat base allowing it to contact the pelvis area described above (at the sacroiliac joint) in a position close to the so-called “sthenic" sitting position, that is to say the right pelvis and the straightened trunk.
- the realization of seats provided with a device according to the invention also includes the possibility of adapting the non-standard shapes and dimensions.
- the support device in question can therefore protrude relative to a file allowing more general support or relative to a support frame if it is the only posterior support available or if it is isolated.
- a removable support system of variable height can be provided.
- Such a system can be fixed in any way to one of the parts of a seat which therefore meets the requirements ters established for the present invention.
- a device according to the invention must stand out sufficiently or be sufficiently isolated from the rest of the posterior support (if it exists) to allow the directly overlying parts (EIPS) and underlying (sacrum) to the support area, to take place freely above and below the device, and thus give rise to the use of the latter.
- the rest of the seat must therefore allow the device to be used.
- this backrest cannot exceed the anatomical relief of the back in position forward. so-called “sthenic" seat to allow maximum support on the device.
- the rest of the file will therefore be at most molded on the back of the user.
- the height and depth dimensions of the seat they must implicitly allow the user to sit with the right pelvis to be able to benefit from the support of the device on the appropriate area (at the level of the sacroiliac joint).
- a posterior support device therefore comprises three support zones: two lateral zones and a central zone set back with respect to the first two. These three areas are rounded forward and intended to support the two iliac bones laterally (below the EIPS) and the sacrum in the middle (above the most posterior point of its posterior surface).
- the three support zones of such a device stand out over a height of approximately 30 mm to give minimum support (allowing an optimal approach to the sacroiliac joint), and sufficient nevertheless given the importance of the pressure of the pelvis on the device at this level.
- a global curvature towards the front of a device meeting these criteria, and the alignment of the three zones on a horizontal plane an example is obtained where these three zones are in the same extension, in the form of a strip ( Figure 4 point 2) can be arranged at the location of a folder described above (at the sacroiliac joint).
- the consistency of the device is such that it can serve as a support for the entire trunk even if it is isolated, without however risking causing tissue damage which covers the skeleton of this area of the pelvis.
- FIG. 1 shows a side view of the skeleton of a vertical pelvis and a vertical partial sectional view along line IV-IV of Figure 4 of a rear support device of a seat according to the invention.
- FIG. 2 represents a rear view of the skeleton of a vertical pelvis with, in hatched form, the area of this relief intended to rest on a device according to the invention.
- 3 shows a schematic view in vertical section along line IV-IV of Figure 4 of a seat according to the invention, a sacrum and a lumbar spine being shown in side view with an iliac bone in the background left.
- FIG. 4 represents the diagram of a seat seen from above, provided with a device according to the invention.
- a system for adjusting the height and depth of the central support zone relative to the two lateral support zones can be provided in order to to adapt the support device to certain particular conformations of basins. Since this adjustment is rarely necessary, a standard device of fixed shape and simple construction is preferably proposed in the present description.
- a support device of this type is shown in 2 seen from above in FIG. 4, this device having the three support zones in the same extension and the middle zone set back with respect to the two lateral zones of approximately 15 mm.
- the device as posterior support secured to a seat is therefore, at the midpoint of its vertical thickness, vertically distant from the plane of the seat (taking into account the crushing of a possible padding) of a height equal to the vertical distance which separates the horizontal plane including the ischia of the support zone described above (at the sacroiliac joint of a pelvis in vertical position). This distance is worth approximately 125 to 175 mm.
- a device according to the invention can for example place this support device on the front side of a suitable backrest according to the present descrip tion or securing it to a support frame, at an average height such that any user can dispose of it, that is to say so that the support points of the device according to the invention can come into contact with the pelvis of the user at the sacroiliac joint as it is recommended in this thesis.
- This average height is approximately 150 mm from the support plane of the ischia.
- a height adjustment system for a device according to the invention makes it possible to adapt this device to the dimensions of the user's pelvis arranged vertically on the seat cushion.
- Such an adjustment system makes it possible to produce adjustable standard office or work seats.
- a system for adjusting the depth of a support device according to the invention can be provided.
- custom-make seats provided with a support device according to the invention provided at the exact height recommended here (at the height of the sacroiliac joint of the vertical pelvis), this height being determinable by an examination simple biometric, using a seat provided with a device according to the invention adjustable in height as above on a graduated scale indicating this adequate individual height.
- the present invention as posterior support of the pelvis in the sitting position, therefore gives effective support to the user and thus stabilizes the base of his spine.
- This allows the trunk to be kept in a correct sitting position with a minimum of tension in the back muscles without risking damage to the joints of the spine and pelvis.
