Definitions

  • the armchair of the invention comprises a frame supporting a seat part, a back part and two armrests, the seat part and / or the back part being pivoted under the action of a motor means actuated by a control means, chair characterized in that the control means consists of an armrest which is movably mounted on the chassis and which is connected to the motor means considered in order to trigger it when the armrest moves.
  • the armrest is slidably mounted on the chassis.
  • the two armrests are movable and constitute, one the means for controlling the movement of the seat part, the other the means for controlling the movement of the back part.
  • the armrest is slidably supported by the chassis by two parallel rods.
  • a spring is disposed between the armrest and the frame to return the armrest to the initial position after it has been moved.
  • the present invention therefore aims to achieve an armchair whose seat part and / or the back part, which are pivotally mounted, can easily be adjusted in inclination by a simple maneuver performed by the person occupying this seat and without it having to move from the position it occupies.
  • the seat shown in the accompanying drawings thus comprises a generally tubular frame 1, on which is mounted a seat part 2 and a back part 3.
  • the seat 2 and back 3 parts are respectively pivotally mounted on the chassis 1 by pins 2 1 and 3 1 .
  • Each armrest 9 is secured to two parallel rods 10 by means of lugs 11, these rods 10 being slidably mounted inside the U-shaped structure 8.
  • Springs 12 are arranged around the rods 10 between the legs 11 and the U-shaped structure 8 so that, after a sliding command of an armrest in the direction of arrow F towards the backrest 3, these springs 12 automatically return the armrest to the advanced initial position.
  • each of the branches of the U-shaped structure 8 is also mounted an angled lever 13.
  • This lever 13 pivots on the U-shaped structure by means of an axis 14 and cooperates with a roller 15 mounted for rotation. on each of the armrests 9.
  • Each lever 13 is moreover connected to a cable 16 disposed in a sheath 17 whose cable stop 17 1 is fixed to the U-shaped structure 8.
  • Each cable is also connected to one of the jacks 4 or 5 so that when one or the other of the armrests slides backwards in the direction of the arrow F, the corresponding roller 15 pivots its lever 13 in order to exert traction on the cable 16. This traction on the cable 16 then triggers the jack 4 or 5 so as to pivotally control the seat part 2 or the back part 3.
  • the person seated on the armchair can, essentially without moving, only by exerting a slight pulling movement on one or the other of the armrests, control the tilting of the corresponding part d 'seat or seat.
  • the spring 12 When the operator ceases to exert the pulling movement on the armrest, the spring 12 returns it to the initial position so that the roller 15 allows the lever 13 to also return to the initial position, which causes the jack to lock and therefore locking the seat part or the seat part in the chosen position.
  • the cylinders 4 and 5 are single-acting cylinders. According to another embodiment, these jacks can however be double-acting in order to be able to control the seat parts and / or the seat parts pivot in both directions from a central position.
  • springs 12 will be arranged around the two ends of each rod 10 in order to maintain the armrests in a median position of equilibrium from which the person occupying the seat can control the tilting in one direction or the other. the seat part or the back part by pulling the armrests in the direction of arrow F or by pushing them in the opposite direction.
