Definitions

  • the present invention relates to a verticalization and seating position device, with particular application to armchairs, seats or fixed or mobile seats.
  • This invention is intended for the elderly, disabled or disabled but capable of a certain autonomy.
  • the lifting techniques of some of these methods cause a complex movement of the front face of the seat, driving it substantially beyond the vertical plane of the front face of the chair. This movement induces a permanent sliding of the seat in relation to the morphology of the user. It has the drawback of causing distortion of the optimum kinematic chain in the lower limbs of the patient.
  • the seat or part of the seat of the chair remains horizontal while it performs a combined movement from bottom to top and from the rear to the front face of the chair. This movement allows only one practical height to be raised vertically from the front of the chair and is therefore only suitable for one user stature.
  • the present invention aims to solve these drawbacks.
  • the invention relates to a lifting device which can be used alone in order to present the user in a determined position facing, for example, another support or seat plane.
  • another object of the invention is to remove, for the majority of users, the need to tie down to the chair during one vertical lift.
  • An additional object is to inscribe the invention in the lines of an armchair with unmarked aesthetics.
  • the object of the invention is remarkable in that it advantageously uses a property of the human anatomy.
  • the place of application of the lifting and retaining force of the user during the verticalization movement is chosen in the sub-femoral area (3) Figures 1 and 3 in particular.
  • the two ischial points (4) of the pelvis extend a few centimeters below the plane of the posterior surface of the body of the femurs, and form an angle with this plane. slightly above 90 °, the top of which can easily be reached by compressing the flesh in the area concerned.
  • this support area Located by definition in the vicinity of the joint of the lower limbs on the pelvis, this support area is more respectful of the user's natural kinematic chain than a system applied under the point of the buttocks. It allows him to make the best use of his muscle dynamics.
  • the invention relates to a device comprising a verticalization and thrust structure characterized in that it has a push bar applying the verticalization and thrust force in the sub-femoral area and in particular in the user's hamstring angle, resting against the ischial protrusions of the user's pelvis, providing resistance to sliding forward during lifting, the user's gluteal and lumbar region remaining outside the push bar.
  • the invention relates to a fixed or mobile armchair or seat of the type comprising a seat and a verticalization and thrust structure associated with the seat and a frame of the chair on which it is articulated around a horizontal axis characterized in that the seat in one or more parts, fixed and movable, has or forms a push bar applying the force of verticalization and pushing in the area under femoral and in particular in the hamstring angle of the user, pressing against the ischial protrusions of the pelvis of the user conferring resistance to sliding forward during lifting, the gluteal region and lumbar of the user remaining outside the push bar.
  • the push bar is located in a horizontal plane at the rear rear end of the movable seat and parallel to the axis of rotation and pivoting thereof, the push bar being attached, integrated or directly belonging to the rear part of the mobile seat.
  • the seat comprises a front part movable around an axis disposed at the front of the chair and a second fixed seat part in a horizontal plane, located between the push bar and the back of the chair.
  • the push bar is located on the front face of the seat. This is made in a single part and is articulated around a parallel axis, its front face is located in the back of the chair.
  • Another characteristic of the invention is that the femoral thrust system generally alone takes care of the patient's lifting effort. To do this, the system is made salient from the initiation of the rotation movement of the seat in the context of the application of the invention to a chair or seat.
  • a non-exclusive way of projecting the pushing system is to make the seat of the chair in two parts initially belonging to the same horizontal plane.
  • This second part can be either fixed and secured to the backrest, FIG. 1, or can be articulated in rotation around the rear face of the front part of the seat.
  • This space is to freely and without constraint accommodate the buttocks and the lumbar region of the user. Its function is to prevent a sensitive component of thrust being applied to the back of the buttocks of the user, tending to drive out of the push bar when, after pivoting, the seat becomes very inclined.
  • the height which must reach the thrust point of the lifting system substantially vertical to the axis of rotation of the seat should be between 60 and 90 cm approximately.
  • the desired height will be obtained by adding the height of the ground to the axis of rotation (28) of the seat (1), and the distance from this axis to the rear part of the push bar (2) integral of the seat in its rotational movement. So it suffices to vary the inine or the other, or these two dimensions at the same time, to vary the lifting height by the push bar accordingly.
  • the distance between the axis of rotation and the push bar can be adjusted to the length of the user's thigh, just as the height from the ground to this axis can be adjusted to the height of his tibia + ankle.
  • the sum of these two dimensions corresponds to the height from the ground to its sub-femoral area (3) when standing.
  • a remarkable anatomical property is that a given variation in the size of the femur corresponds to an almost identical variation in the size of the tibia.
  • the position of a first pair of locations (6) and (10) of the axis of rotation (28) of the seat (1) of the seat on the frame (9) of the chair is determined, in such a way that the height from the ground / axis of rotation corresponds to the height of the tibia plus the ankle of the individual of the smallest size to be raised, so that a distance is determined from this axis (28) to the bar thrust (2) as it corresponds to the length under femoral of this same individual, while to properly verticalize each individual of larger size, the geometric location of the locations of the axis of rotation (28), will be a plane inclined at 45 ° passing through the center of the first location of the axis (28) and moving away from it in the direction of the upper front part of the front face of the chair.
  • the number of pairs of locations for the axis of rotation on the movable seat and the frame (9) of the chair will be determined according to the desired verticalization accuracy.
  • This characteristic is used in a preferred embodiment of the invention where the movable branch (19) of the mechanism (24) describes a constant arc close to 90 °, while the end of this branch (19) provided with contact rollers (20), moves relative to the seat under the plate (5) of the latter.
  • the same mechanism can be used as it is, without modification of its positioning, whatever the choice of the couple of locations of the axis of rotation, and despite a noticeable elongation of the movement of the seat for large sizes .
  • the armchair which is symmetrical with respect to its median longitudinal plane, comprises a pivoting seat (1) articulated in rotation on the chassis (9) of the armchair around a horizontal axis (28).
  • the position of the axis of rotation (28) can be chosen from several pairs of matched locations 6/10 - 7/11 and 8/12, of which 6-7 and 8 belong to the chassis (9) and (10), (11) and (12) to the movable seat (1), in which the user can position the axis (28) when the seat (1) is at rest; that is to say that its plate (5) is horizontal, its front face (33) in the same plane as the front face (34) of the chassis (9), and that the angles ⁇ and ⁇ of the seat (1) and the chassis (9) of the chair seen from the side, are superimposed.
  • the seat (1) consists of a plate (5) comprising, at its rear end, a sub-femoral push bar (2) protruding above the plane of the plate and of sufficient length to allow support simultaneous two ischions.
  • This bar (2) is integrated into the thickness of the cushion (13), consisting of a lower plate (15) of foam with a density greater than that of the plate (14) so as not to risk injuring the user during use, or be uncomfortable when seated.
  • the profile of this bar can be cylindrical or angular.
  • the push bar is arranged parallel to the front face of the seat (1).
  • the pivoting seat (1) has 3 locations (10, 11 and 12) of the axis (28) located in the same plane making an angle ⁇ of 45 ° with the plate (5) of the seat (1).
  • the distance from the axes of the locations (10, 11 and 12) to the front plane (33) of the seat (1), FIG. 4, is the same as the distance of their respective correspondents (6, 7, 8) from the plane of the front face (34) of the chassis (9), FIG. 5.
  • the angle of inclination ⁇ of these locations with the plane of the seat (1) at rest is 45 °.
  • the free space (32) located at the rear of the push bar (2) is provided to receive the fixed part (16) of the seat, so that the collaboration of the mobile seat (1), at rest, with the fixed part (16) creates a single plane where the user can sit.
  • the space between the face (30) of the push bar and the front face of the chair back is advantageously of the order of 15 cm when the seat (1) is at rest. This distance must always be greater than 7 cm.
  • the armrests are integral with the movable seat (1); their enveloping appearance is reassuring for the user.
  • the frame (9) of the chair symmetrical with respect to its median longitudinal plane, comprises two sides (36) and a backrest (35) which is fixed to the fixed part (16) of the seat.
  • the backrest (35) can be orientable according to known techniques.
  • the beams (26) and (37) serve to support the mechanism (24).
  • a lifting mechanism (24), acting as a compass, FIGS. 1, 2 and 3 comprises a branch (23), fixed, integral with the chassis (9), and a branch (19) articulated in rotation around the axis ( 25).
  • Motor means (21) and (22) interposed between the branches (23) and (19) cause, on command of the user, the opening or closing of the compass between extreme positions of the branch (19).
  • the drive means (21) may consist, for example, of jacks of different types or similar members.
  • a jack possibly telescopic, can exert its thrust directly between a fixed point of the plate (5) of the seat (1) and the transverse beam (26) of the frame (9) of the chair, without it being necessary to use an additional mechanical intermediary.
  • the return to the horizontal position of the movable seat (1) when empty is ensured by the end of the axis (27) on the rebates (38), integral with the plate (5).
  • the push bar can be constituted by the rear part of the plate (5) itself. It can, in another embodiment, be movable relative to the plate (5). To this end, a reference makes it integral with the mechanism (24) which gives it, firstly the phase of rotation of the mobile seat (1), an autonomous movement raising the push bar above the plate (5 ), before training the latter in a joint movement of the push bar / mobile seat, until the end of the verticalization.
  • Another modification can relate to the realization of the seat which can be made in one piece.
  • the rear part (16) is articulated in rotation about an axis located in the vicinity of the rear face of the plate (5) of which it is integral.
  • the part (16) rocks backwards until it forms an angle of approximately 90 ° with the plate (5) which it then accompanies in its movement.
  • the total depth of the seat of the chair is defined as the distance between the front face (39) of the backrest (35), at the level of the seat (16), and the vertical plane of the most anterior point of the mobile seat (1) at rest.
  • the depth of the pivoting seat (1) is defined as the distance between the plane of the foremost point of its front face (33) and the plane of the rear face (30) of the push bar. This depth is between a quarter and six sevenths of the total depth of the seat of the chair.
  • the distance between the axes of the pairs of locations of the axis (28) and the apex of the angle of the faces (29) and (30) of the push bar (2) is between 15 and 50 centimeters.
  • This embodiment is obtained by positioning the push bar (2) on the front face (42) of the seat (43) which is produced in this case in a single part.
  • the seat is articulated around an axis (44) parallel to its front face and located in the back (45) of the chair.
  • the verticalization and lifting device of the user (46) can in particular be an electric actuator for example, which exerts its force between the push bar (2) and an anchor point (46) located in the lower front part of the armchair, or its frame.
  • the user is positioned as shown in Figure (10) so that the push bar (2) is in front of the tip of his ischia (4). He can then activate the verticalization device which he stops when he reaches the height that suits him.
  • the push bar (2) does not protrude or slightly beyond the front plane of the legs of the chair.
  • the push bar in its highest position, (for example 84cm in height under the femoral corresponding to a developed size of 1.85m) the push bar is still in a vertical plane close to the vertical plane of the face of the chair .
  • the axis of rotation (44) of the seat on the backrest will be placed at a height from the ground close to the average height that reaches the push bar between its highest and lowest position.
  • the arrangement of the jack (46) between the push bar (2) and the anchor (47) makes it possible to carry out with the same motor means the additional functions illustrated in FIG. (7), that is to say tilting and raise the back of the chair that is articulated around an axis (48), then tilt and raise a leg rest (48) articulated around an axis (50).
  • the verticalization structure referenced as a whole by (51) is arranged vertically on a base (52) mounted for example on a roller.
  • the upper part is arranged to receive the push bar (2) which is applied in the sub-femoral area (3) and in particular in the ischi-femoral angle (7) of the user.
  • the device comprises at least one vertical column mounted on a base on which slides from top to bottom a ring (53) on which is horizontally secured a bearing (54) whose end receives the bar thrust (2).
  • a jack (55) or similar member is fixed to the base and to said bearing surface and allows the lifting of the push bar.
  • Such a simplified device allows the user to use it to sit on all elements, all suitable conventional seating elements such as chair, wc cabinet, bidet, bed and other similar products.
  • the verticalization structure allows height adjustments to position the user at any desired height.
