Definitions

  • the present invention relates to automatic transformable seats, which are intended, first of all for the elderly and the disabled, but whose uses are becoming more and more widespread with a view to increasing comfort in everyday life.
  • These seats generally comprise, on the one hand, a fixed base or base, containing the energy source or sources, generally actuated jacks, and the mechanical elements transmitting the movements of these jacks to movable parts, and on the other hand said movable parts which can be the backrest or support, the seat itself and / or an extension of this seat constituting a footrest.
  • These different moving parts have different functions, which are however more or less complementary.
  • the tilting of the backrest, then of the seat is complementary to facilitate the transition to standing by an elderly person or during rehabilitation of the lower limbs, which are therefore insufficient to fulfill their normal functions.
  • a seat must both allow the backrest to be reclined and the footrest to be raised.
  • many relaxation seats must allow all possible combinations of in clinches of their various parts.
  • the present invention makes it possible to eliminate all of these drawbacks, for a seat fulfilling the maximum of useful functions.
  • the seat according to the invention consists of a fixed base, ensuring the seat of the seat on the ground, and in which is housed a single cylinder and all of the control linkage of the inclination of the seat itself, the backrest and the footrest, the movement of the piston of the jack controlling a main lever exerting its action sequentially on the tilting of the backrest, then, separately or simultaneously that of the footrest, action of the main lever itself resulting from its contact, direct or via a secondary lever, with stops triggering the tilting of levers secured to the respective axes of rotation of the three aforementioned parts of the seat, and this in one direction (or order) or in the other.
  • the single cylinder which determines all the deformations of the components of the seat between the fully extended position and the standing position acts on a single point of one of these elements, and it is this element who, playing the role of relay, in turn controls the deformations of the assembly.
  • said command is broken down into three kinematic chains each determining in turn one of the phases of said distortions.
  • a support element such as a cushion or padding, is slidably mounted on the backrest, so as to facilitate the movement of the user's back when the seat is deformed.
  • a fixed base which serves as a seat for the seat.
  • the footrest D is hinged around an axis concentric with the B axis, while the E backrest is hinged around the E axis located behind the seat C.
  • the basic operation of the headquarters is as follows.
  • piston 4 will reach another stop cooperating with a lever similar to the lever J ′, and acting on a sleeve (not visible in the drawing) coaxial with the axis B and thanks to which it can always pivot in the direction F 1 the footrest D, at an angle
  • FIGS. 1 and 2 illustrate an effective embodiment of this (or these) mechanism (s), as identified in the preamble of the present description.
  • this mechanism may comprise only one group of elements corresponding to the first kinematic chain, it is preferable, for reasons of symmetry of efforts, to have two such groups, distributed on each side of the seat, as shown in the two figures.
  • the backrest 1 is articulated at the seat 3 around axes 2 located at the curve angle and in the extension of a cross-member 30.
  • the footrest 5 is articulated to the seat 3 around axes 4 located at its end.
  • the seat 3 is reinforced at its curve 25 by a cross member 31, also serving as a point of attachment to elements of the kinematic chains.
  • the 1-3-5 mobile assembly is supported, via the kinematic chains, by a base consisting of a horizontal frame 6 reinforced by crosspieces 32 and 33 and two vertical rectangular frames 34-34 '.
  • the operation of the mechanism results from the action of a single jack 7, hooked on the one hand to an axis 8 carried by a support 9 secured to a cross member 35 of the backrest 1, and on the other hand to an axis 10 carried by a support 36 secured to a spacer 37 joining the crosspieces 32 and 33.
  • each frame 34-34 ' On each side of the seat, that is to say approximately in the vertical plane of each frame 34-34 ', is mounted the first kinematic chain.
  • This first kinematic chain consists of a main lever Il (or II ') articulated on the one hand in 2 and on the other hand in a fixed point 12 of the frame 34 (or 34'), the main levers 11 and 11 ' being joined by a horizontal crosspiece 13, and a deformable set of links 14, 16, 18 mounted so that the link 14 pivots at one end at an intermediate point 54 of the lever 11, and at the other end 15, it is pivotally joined at the ends respectively of the link 16, which is also articulated at 17 at the base of the backrest 1, and of the link 18, which is also articulated at 19 at the frame 6 of the base.
  • Each of these chains is based on the principle of the control triangle: a triangle pivots around one of its vertices under the action of a connecting rod connected to a point of action of the jack, so that connecting rods fixed to its others vertices determine the movements of the seat elements.
  • a triangle 20 is articulated at its top 21 to a connecting rod 39 connected to the fixed point 38 located on the cross member 32, that is to say integral with the attachment point 10 of the jack 7
  • a connecting rod 24 fixed at 40 to the cross member 31
  • a connecting rod 26 fixed at 41 to the cross member 32.
  • this second chain is then as follows: when the seat 3 rocks forwards, the triangle 20 also rocks forwards under the pressure of the connecting rod 24; the top 23 lowering, it drives the connecting rod 26 which in turn will lower the footrest 5.
  • a triangle 28 is articulated by its apex 42 to a connecting rod 43 pivoting around the fixed point 29 of the cross member 32, and also to a connecting rod 44 pivoting around an axis 45 fixed to the cross member 13.
  • a connecting rod 47 pivoting at a point 48 of the cross member 31.
  • a link 50 whose other end is connected at 51 to the ends of a lever 52, pivoting at the point of attachment 8 of the jack 7 on the support 9, and of a connecting rod 53 also pivoting on the axis 45.
  • this third chain is then as follows: when the jack 7 is deployed, to raise the backrest and the seat, and lift the seat, the assembly of the connecting rod 50 and the lever 52 constitutes a global lever (the connecting rod 53 playing only the role of return) exerting a traction towards the rear of the apex 49 of the triangle 26, which is then raised by pivoting around the apex 42. As also this apex 42 is also lifted by the connecting rod 44, l 'overall effect is to complete the lifting of the seat 3 when, conversely, by the play of the second kinematic chain, the footrest will complete to retract.
  • the seat leads its user to find themselves practically standing without having to make the slightest effort.
  • a lining mounted on ball bearings allows the back of the user to slide along the backrest. This results in an additional increase in comfort.
  • the seat according to the invention has just been described in a particular embodiment, namely that of a single-seat armchair. We can make many variants, by separating the two portions shown in Figures 1 and 2 of a greater length, to make a sofa or a bed with the same advantages.
  • the cushions and upholstery may be very varied, the arms being able to conceal the control of the seat mechanism, or to contain various arrangements all aimed at improving the comfort of the seat, for example a telephone handset, a remote control of an audiovisual installation, a mini-bar or the like.
