Definitions

  • the invention relates to the field of articulated seats with a view to modifying the seat in an ergonomic sense.
  • the invention relates in particular to applications as varied as domestic seats, office seats, automobile, train or airplane seats, relaxation seats, or seats or armchairs for sick or disabled people.
  • the articulation mechanisms allowing the movements of such seats are covered by the invention.
  • the seats and articulated mechanisms according to the invention allow so-called conventional postures but also so-called relaxation postures. To do this, the mechanisms allowing the relative movements, in particular of the seat and the backrest, are assisted and motorized.
  • an articulated seat comprising a base which supports, through an articulated connection, a seat, a backrest and a support element for the legs.
  • An articulation with connecting rods and jack allows easy passage between several positions, in particular between a seated position to a position in inclined elevation. This mechanism is relatively complex to implement, by the number of parts involved as well as by the associated connections.
  • the invention aims to remedy the drawbacks of the state of the art and in particular to provide an articulated seat device of simple design but allowing relative movements of the seat and of the backrest of great amplitude which induces good reliability.
  • the invention therefore relates to an articulated seat device comprising a fixed base on which rests a movable assembly comprising a seat and a movable backrest relative to the base by virtue of an articulation mechanism cooperating with a motorized means.
  • the articulation mechanism comprises at least one multilinear path cam fixed on the base and in which slides a roller cooperating with said motorized means which ensures its displacement in both directions of the multilinear path.
  • said cam being flat and oriented in a longitudinal plane of the seat.
  • longitudinal plane of the seat is meant a plane which contains a longitudinal axis of the seat, that is to say an axis which extends along the length or greatest dimension of the seat.
  • said motorized means comprises a single actuator controlled by a motor, to which said roller is connected.
  • said motorized means comprises a motorized roller cooperating with a cam provided with teeth provided on said cam track.
  • the teeth are erected towards the inside of the path of cam, in the main plane of the cam and they cooperate with those of the pinion; here we have a pinion-rack gear type connection.
  • said cam track comprises a first, second and third substantially linear portions, and juxtaposed. It is therefore a unique and relatively easy to manufacture part which is chosen here to define the movements of this articulated seat. The movements induced by such a cam profile are adapted to the desired synchronizations and allow interesting amplitudes.
  • the first portion of said cam track is substantially vertical and allows, when the roller traverses it, the simultaneous rotation of the seat and of the backrest around a first axis of rotation O perpendicular to the longitudinal axis L of the device and located substantially in the middle of the seat.
  • the second portion of said cam track forms an angle of approximately 120 ° with the first portion of said path, the respective curvatures of the first and second portions forming a concavity, and in that the second portion of the cam track cam allows, when the roller traverses it, the rotation of the backrest relative to the seat around a second axis of rotation O1 constituting the common pivot edge between the backrest and the seat, said second axis of rotation being perpendicular to the longitudinal axis L.
  • the third portion of the cam track is substantially parallel to the first portion of the cam track so as to form an inflection point with the second portion, said third portion allowing, when the roller traverses it, the rotation of the backrest and seat around the first axis of rotation O.
  • the articulated seat may further comprise means capable of allowing the support of the lower limbs, and means for controlling their movement which cooperate with the motorized means and the cam.
  • the means for controlling the movement of the supports of the lower limbs are functionally linked to the roller, preferably in the third portion of said cam track.
  • the means for controlling the movement of the supports comprise a first connecting rod having a first end capable of sliding in a part of the cam track and a second end cooperating with a first end of a second connecting rod. , said second link cooperating at its second end with a first end of a third link, the second end of which constitutes a pivot connection with the support for the lower limbs.
  • said actuator can be fixed on the base at the level of the bottom of the backrest. Without departing from the scope of the invention, said actuator can be fixed to the backrest, in its uppermost part.
  • the figures 1 to 5 show both the positions of the articulated seat according to the invention and the particular mechanical connections making it possible to obtain these different positions.
  • the fixed base (except the cam) is not illustrated in these figures for reasons of clarity of description; only the mobile assembly is therefore represented.
  • This movable assembly comprises in particular a seat 1 and a backrest 2 movable relative to each other and relative to the fixed base.
  • the articulation mechanism is shown diagrammatically and comprises a cam 4 with a non-linear path which cooperates with a motorized means such as a jack (not shown in the figures 1 to 5 ) and a roller 5 fixed to the cylinder.
  • the roller 5 is shown schematically by a point, here placed at the bottom of the backrest 2.
  • the mechanism may additionally comprise means 3 capable of allowing the support of the lower limbs such as the legs or the feet.
  • a connecting rod mechanism 6 is provided, operatively connected both with the lower surface of the legrest 3 and with the cam track.
  • the articulated seat device is in the so-called starting position where the seat 1 is horizontal and where the backrest 2 makes an angle of approximately 95 ° with the seat 1.
  • the roller 5 is placed at one end of the cam track .
  • the figure 2 illustrates a so-called security position; a rotation around a first axis O of the whole of the seat device is effected between the starting position of the figure 1 and that of the figure 2 .
  • the roller 5 has moved in the cam track, on a first portion 41. This position, with a slight inclination of the seat towards the rear of the seat, prevents the seated person from sliding forward. ; in other words, she holds him in the sitting position.
  • the figure 3 differs from figure 2 by the position of the backrest 2 which has rotated around a second axis O1 vis-à-vis the seat 1. This is the only movement observed in this phase. Between the position of the figure 2 and the one at the figure 3 , the roller 5 has traveled a second portion 42 of the cam track. The user is thus in a semi-relaxed position. Note that during all these phases, the leg support remained motionless.
  • the figure 4 shows a so-called comfort position in which the user is almost lying down.
  • the seat 1 and the backrest 2 have made a simultaneous rotation of approximately 35 °.
  • the roller 5 has started its course in the third portion 43 of the cam track. At the same time, the roller 5 has come into contact with the end of the connecting rod system so that the leg support 3 has started to move.
  • the figure 5 illustrates a position of total relaxation in which the legrests are fully extended and have an almost horizontal position. Between the positions of the figure 4 and some figure 5 , the roller has traveled the entire third portion 43 of the cam track. It comes to a stop at the end of the cam track.
  • the figure 6 is a diagram showing the different positions of the articulated seat, from the seated position (1) to the fully relaxed position (4).
  • the first axis O is fixed relative to the fixed base (not shown) and, consequently, the cam 4.
  • the seat 1 is thus mounted so as to be able to rotate about the first axis 0 relative to the fixed base and the backrest 2 is mounted so as to be able to rotate around the second axis O1 on the seat.
  • the roller 5 traversing the cam 4 is located at the bottom of the backrest 2.
  • the means of motorization of the device comprises, according to a preferred embodiment of the invention, a single cylinder which, depending on the direction required for the movement, exerts a thrust or else a traction on the roller which itself causes successively rotations around the first axis O (simultaneous rotation of the seat and the backrest) and around the second axis O1 (rotation of the backrest with respect to the seat).
  • a fluid movement is obtained, in one direction as in the other direction of movement.
  • the angle points of the cam track in no way disturb the operation of the seat according to the invention; on the contrary, they make it possible to achieve a damping of the speed of the movement at each change of trajectory in the cam path. Smooth movement of the seat and backrest results.
  • This is due to the diameter of the roller which induces a rotation of this one around its instantaneous axis of rotation (point of contact between the roller and the cam track) at the level of the trajectory changes, which prevents a sharp angle trajectory. of the roller and creates a damping of the speed of the movement.
  • the diameter of the roller implies fluid sequences of movements; the larger the diameter of the roller, the lower the acceleration / deceleration stops and starts.
  • the figure 7 shows the cam 4 which is a flat part of a certain thickness, for example 12 mm, made of steel by a laser cutting machine or by a sheet metal punching machine or else by machining, by molding.
  • the cam 4 is placed in a longitudinal plane of the seat. According to the mechanical stresses undergone by the roller and linked in particular to the maximum weight of the person supported by the seat, the dimensioning of the roller is carried out by those skilled in the art according to the rules of the art.
  • the positions of the rotation axes O1, 02, of the jack represent parameters taken into account.
  • the figure 7 illustrates the cam track defined according to the illustrated embodiment, and which makes it possible to induce the relative and absolute movements of the seat 1 and of the backrest 2, or even of the legrest 3.
  • a first portion 41 substantially straight but which has a slight curvature, the general orientation of which is close to the vertical.
  • the second portion 42 of the cam track is substantially straight but slightly curved; it forms an angle of approximately 120 ° with the first portion 41 and these two portions together form a concavity.
  • the third portion 43 which connects with the second portion at an inflection point.
  • the third portion 43 is substantially parallel to the first portion 41.
  • the number and geometry of the constituent portions of the cam track depend on the desired movement sequences of the seat 1 and of the back 2.
  • the width of the cam track is calculated and the dimensions of the roller which travels therein are chosen accordingly.
  • the dimensions of the running roller are as follows: thickness of 11mm; 19mm diameter, for a cam having a thickness of 12mm.
  • an assembly consisting of a rotary motor, a pinion can form a motorized roller; teeth are then provided on the cam track, which cooperates with the motorized roller.
  • This assembly replaces the cylinder, roller and smooth cam assembly described above.
  • a first connecting rod 61 has a first end capable of sliding in a part of the cam track and a second end cooperates with a first end of a second connecting rod; said second connecting rod 62 cooperates via its second end with a first end of a third connecting rod 63, of which the second end constitutes a pivot connection with the leg or footrest support 3.
  • the roller 5 exerts a thrust force, in the third portion 43 of the cam track, which makes it possible to move the leg support 3 from an almost vertical position to a horizontal position.
  • the figure 8 illustrates by a schematic perspective view a wheelchair according to the invention.
  • a support 3 which is here a support for the feet; the control means of the support 3, namely the connecting rods are also shown, in particular the third connecting rod 63.
  • the joint according to a preferred embodiment of the invention is shown on figure 9 where we see in particular the cam 4 comprising three portions 41, 42, 43 of the cam track.
  • the roller 5 is here placed at the end of the cam track and it can be seen that the arm of the jack 7 is then extended.
  • a motor 8 makes it possible to actuate the jack 7.
  • a control unit (not shown) makes it possible to control not only this motorization but also any other technically equivalent means and any additional means useful for the proper functioning of the invention.
