Definitions

  • the present invention relates to armchairs, more particularly but not exclusively, wheeled, which are used by the disabled and disabled and it equally applies to wheelchairs, folding or not.
  • Such a position is not capable of bringing a readjustment to life common and does not facilitate social contacts. Also, such a sitting position, maintained for relatively long periods, is responsible for a physical degradation, such as loss of angular range in the lower limbs, defective blood circulation, slowing digestive functions and intestinal, bone fragility, etc.
  • the chassis supports an articulated structure comprising a backrest, a seat and a footrest.
  • a structure is mounted articulated by the seat on a front axis horizontal, perpendicular to the vertical plane of symmetry of the chassis.
  • the structure articulated can be ordered with full motorization or assistance, to make shift the seat from a lowering position to a verticalization position and Conversely.
  • Such chairs are generally referred to as “chairs verticalizers or verticalizers ".
  • the armchairs of the above type have certainly resolved, for great part, the disadvantages arising from the use of a conventional armchair.
  • the articulated structure is composed of an element seat, a backrest and a footrest element which must therefore ability to occupy relatively a general position of the seat or seated type and be placed in line with each other in the vertical position or standing.
  • the structure articulated consists of two symmetrical articulated lateral systems comprising each a first deformable quadrilateral contributing to the support of the seat, composed of two bars, respectively upper and lower, articulated on the front part of a chassis and linked to their rear part by a part spacer.
  • Each lateral articulated system also includes a second deformable quadrilateral contributing to the support of the footrest, as well as a frame backrest which is articulated on the first quadrilateral, opposite the second quadrilateral, through at least the spacer and which includes at least one upright secured to the spacer.
  • the chair includes a set of maneuvers, interposed between the side assemblies and the chassis and assuming a control and control of the relative pivoting of the lateral assemblies from a lowering position to a vertical position of the structure relative to the chassis and vice versa.
  • this stand-up chair is characterized in that it further comprises means for automatically modifying the inclination of the backrest with respect to the vertical direction in the sagittal plane, between the positions lowering and verticalization.
  • the means for automatic modification of the inclination thus allow either a slight tilting of the backrest forwards when switching to vertical position, or, on the contrary, a slight tilting backwards during the transition from sitting to standing.
  • the automatic modification means can be performed in any suitable manner and, for example, include a system of connecting rods and appropriate references to ensure this change.
  • the means of automatic inclination modification include, for each system articulated side, the spacer and the first deformable quadrilateral which has a different shape from that of the parallelogram.
  • the modification means automatic backrest tilting are adjustable, so as to allow choice of direction and / or amplitude of the modification.
  • the means of modification are then, preferably but not necessarily, adjustable so as to present a neutral position in which the angle of the amounts, relative to the vertical in the sagittal plane, is identical in position lowered and in vertical position.
  • the. adjustable means for automatically changing the inclination of the backrest act on the shape of the first deformable quadrilateral.
  • the implementation for the modification automatic tilting of the backrest of the shape of the first quadrilateral deformable, provides a simple device with a reduced weight.

  • the spacer includes at least two fixing positions for the articulation point corresponding to the lower bar of the first parallelogram.
  • the chair stander in order to allow better adaptation of the stand-up chair to the morphology of its user, also includes means for adjusting the angle of each amount in relation to the corresponding spacer.
  • Means for adjusting the relative angle of the upright and the spacer can be done in any suitable way.
  • the means for adjusting the angle of the amount in relation to the spacer include, for each amount, a pivot for fixing the upright on the articulation piece, allowing movement of rotation of the upright, between a folded position against the upper bar of the first quadrilateral or the seat of the chair and a raised position, as well as means of locking of the upright in the raised position which are integral with the part and movable on the latter, so as to allow modification continues from the angle between the spacer and the upright in the raised position and locked.
  • a stand-up chair according to the invention can comprise different types of propulsion, such as drive wheel systems electric or, preferably, manually propelled wheels.

  • the spacer 20 defines a small rear side P P of the first quadrilateral and the points of articulation 21, 22 on the front part of the frame defining a small anterior side P A , as can be seen in FIG. 4.
  • Each articulated system 13 further comprises a second polygon and, according to the example illustrated, a second deformable quadrilateral 26 , shown diagrammatically in FIGS. 2 and 3 in broken lines, connecting the first deformable quadrilateral to a jamb or upright 2 7 intended to support, alone or in combination with the leg or amount counterpart, a footrest 33.
  • Each articulated system 13 finally comprises a back frame comprising two uprights 35 , each articulated on the first quadrilateral 13 , opposite the second quadrilateral 26 , by means of the spacer 20 .
  • the backrest uprights 35 are, moreover, connected by a cross-member 36 .
  • each articulated system further comprises an operating assembly 40, interposed between the first quadrilateral 17 and the chassis 2 and, more particularly, the corresponding half-chassis 4 .
  • Each operating assembly 40 comprises a first lever 41, articulated on the rear part of the chassis, by means of a pivot 42 and, at the end of a second lever 43, by means of a pivot 44 .
  • the other end of the second lever 43 is then articulated on the first quadrilateral and, in the example shown, the bottom bar 19 via a pivot 45 and a fixing part 46 integral with the second lever 43 .
  • Each maneuvering assembly also includes a maneuvering handle 49 which could be qualified as multiple sockets, insofar as it must allow the user of the wheelchair to apply a force to this handle, both in the context of the lowering or sitting position illustrated in fig. 2 , that in the block of the verticalization position B illustrated in FIG. 3 and during the transition phase or verticalization-lowering movement.
  • a maneuvering handle 49 which could be qualified as multiple sockets, insofar as it must allow the user of the wheelchair to apply a force to this handle, both in the context of the lowering or sitting position illustrated in fig. 2 , that in the block of the verticalization position B illustrated in FIG. 3 and during the transition phase or verticalization-lowering movement.
  • the verticalizing chair described above also includes assistance means 50 .
  • these assistance means are constituted, for each of the articulated systems, by a gas spring 6 , interposed between the first quadrilateral 13 and the front part of the chassis 2 .

  • it will for example be possible to adopt a position slightly inclined towards the front or the rear of the backrest, in the lowering position, while the backrest will automatically adopt a position, for example but not exclusively, substantially vertical in the verticalization or standing position of the structure, in order to give a satisfactory orientation to the bust of the user in the standing position.
  • This automatic modification of the orientation of the file can be ensured by different ways.
  • the means 60 for automatically modifying the inclination of the backrest comprise, for each lateral articulated system, the spacer 20 on which the corresponding backrest amount 35 is adapted so as to form, with said piece spacing, an angle ⁇ which remains constant during the displacements of the articulated structure.
  • the automatic modification means 60 further comprise the first deformable quadrilateral 17, composed of the two long sides G S , G I and the short sides P B , P A.
  • the Applicant has had the merit of highlighting that a slight modification of the deformable quadrilateral 17 relative to the perfect parallelogram, allowed to obtain a variation of the inclination ⁇ between the lowering or sitting positions and the verticalization or standing position of the articulated structure.
  • the plaintiff advocates adopting a form different from that of parallelogram for the first quadrilateral, in order to obtain such a modification automatic.
  • the shape chosen for the first deformable quadrilateral is adopted so that the long sides G S and G I have lengths L S and L I equal, while the length L A of the short anterior side P A is chosen so as to be greater than the length L P of the short posterior side P P.
  • This conformation of the first deformable quadrilateral then makes it possible to obtain a rearward displacement of the backrest when passing from the sitting position to the standing position.
  • the backrest when the short posterior side P P has a length greater than that of the short anterior side P A , the backrest will tend to tilt forward when passing from the lowering position to the verticalization position. On the contrary, when the short side P P has a length shorter than that of the short anterior side P A , the backrest will tend to tilt backwards when passing from the lowering position to the verticalization position.

  • the adjustment means 70 can be made in any suitable way. According to the embodiment of the chair, illustrated and described above and as shown in more detail in FIG. 5, the adjustment means comprise, for each lateral articulated system, a pivot 71 for fixing the backrest upright 35 on the spacer, so that the upright 35 has, opposite its part 72 for supporting the folder, a locking segment 73 .
  • the backrest upright 35 is then movable, between a folded position against the upper bar of the first deformable quadrilateral or the seat of the stand-up chair and a raised position for using the chair. stander 1 .
  • the inclination adjustment means 70 then further comprise means for locking the upright 35 and, more particularly, of its segment 73 in the raised position, so that the upright 35 is immobilized relative to the part d '' spacing 20 .
  • the locking means comprise a finger 74 integral with the locking segment 73 and a kind of striker 75, integral with the spacer 20, being movable relative thereto, so as to allow, by its movement, a change , preferably continuous, of the angle ⁇ .
  • the keeper can, for example, be mounted in a groove by being moved in translation by means of an Archimedes screw.
  • means 70 for adjusting the static inclination ⁇ of the upright 35 relative to the spacer 20 and means for automatic modification 60 of the inclination of the backrest, between the lowering position and the position of verticalization then makes it possible to offer optimal comfort to the user of the armchair, by allowing fine adjustments of the inclination of the backrest and, in particular, by making it possible to search for an inclination for the backrest, both optimal in the sitting position and in standing position.
  • the adjustable means for automatic modification 60 of the inclination ⁇ of the backrest, between the sitting and standing positions are produced by acting on the length L P of the small posterior side P P of the first deformable quadrilateral .
  • the adjustable automatic modification means 60 can be produced by acting on another side of the deformable quadrilateral.
  • fig. 6 illustrates another embodiment according to which the means of modification 60 of the shape of the first adjustable quadrilateral are constituted by means of continuous modification of the length of the upper bar 18 of the first deformable quadrilateral.
  • These continuous modification means 60 are, according to the illustrated example, constituted by a ring 90 connecting two segments 91 , 92 constituting the bar 18 and linked, to each of these segments, by a thread, so that a rotation of the. ring, in one direction, allows an increase in the length L S of the upper segment 18 and, in the opposite direction, a reduction in the length L S of the upper segment 18.
