Definitions

  • the invention relates to a wheelchair lift seat for the disabled and sick, offering them the possibility of accessing, always in the seated position, plans of different levels.
  • the present invention overcomes this drawback by a simple and reliable mechanism which will provide the patient with increased autonomy.
  • this chair offers many advantages.
  • this chair is suitable for the different morphologies of users, and facilitates transfers.
  • This seat is done by means of an endless screw driven by a toothed plate and a chain, the rotation of which is ensured by the patient by means of a crank (the toothed plate can be replaced by a pulley and chain by a belt).
  • This elevation concerns the seat, the backrest, the armrests and the footrest.
  • the armchair consists of two parts which are the frame (I2) on which the drive wheels and the directional wheels are fixed, and the seat, backrest, armrests and footrest (I), completely independent of the frame (I2) .
  • the elevation of the aforementioned assembly is ensured by a pin (3) which pushes fixing lugs (2) and moves on a worm (4), itself maintained by tapered bearings (5 5 ′) .
  • the rotation of the worm (4) is ensured by a toothed plate (6) actuated by a drive pinion (8) and a chain (7), both connected to a gear.
  • This drive pinion (8) is fixed on a rod (I0) whose rotation is made by bearings (9 9 ′).
  • a return sprocket (I3) driven by a chain (I4), is itself connected to another sprocket of different diameter (I3 ′).
  • This return pinion (I3) made integral with the crank (II) by a rod (I8), mounted on bearings (I9 I9 ′), ensures a limited number of turns, while reducing the force supplied to the crank (II ) by the user.
  • an electric actuator which is actuated by an electric motor, replacing the worm device, which makes it possible to obtain a lighter chair, and a reduced size of the device.
  • This motor runs on battery or batteries to ensure autonomy.
  • the seat is made rotary by the addition of a double rolling plate (I5), placed between the jack or the worm and said seat, which allows with increased maneuverability the possibility of different positions for the patient.
  • a mechanical device by cable (I6) or rod, allows the lateral pivoting of the footrests, which are split into two parts, which ensures ease for the patient when he is installed on the chair.
  • the controls for pivoting the footrests are located on each side of the seat (I7).
