Definitions

  • the present invention relates to chairs with a seat and back rest of adjustable inclination and more particularly regards a chair having a seat and back rest which are susceptible to angular correlated and synchronized movements.
  • the aim of the present invention is to supply a chair with a seat or back rest which are susceptible to correlated, synchronized inclinations but without having to resort to mechanical devices or springs, thus having a simpler structure fitted with an elementary lever system.
  • the backward flexing movement of the body of a person who sits begins with the need to go from an upright position, for example a working position, to a more relaxed position, for example in a conference position.
  • the chair in accordance with the present invention has a back rest whose backward flexing movement does not depend on a spring but makes use of the weight of the person on the chair through contrast and reaction.
  • the movement of the back rest following the strain which tends to adjust the inclination will always be in proportion to the position and weight of the person using the chair.
  • the backward inclination movement of the back rest is coupled with the lifting of the rear part of the seat which is always bucked through the weight of the seated person.
  • the total adjustable angle between the starting position of the seat/back rest therefore corresponds to the sum of the two modifying angles of the inclination of the seat and of the back rest.
  • the here proposed chair essentially has a seat (11) and a back rest (12) assembled on any support or base (13).
  • the seat (11) is pivoted at the front to the base (13) through a transversal oscillation axis (14).
  • the back rest (12) is pivoted on its lower part to the back of the base (13) through a transversal oscillation axis (15).
  • the oscillation axis (14, 15) respectively of the seat and back rest are parallel to each other.
  • the back rest (12) has a lower lever arm (12a) angled in respect to the back rest itself. Said lever arm (12a) can be integral or inserted and fixed to the back rest in order to move and oscillate with the latter.
  • the lever arm (12a) extends forwards underneath the seat, away from the oscillation axis of the back rest.
  • the rear part of the seat (11) rests against the lever arm (12a) of the back rest giving the two components the possibility of oscillating on their respective axis (14, 15).
  • the seat and the back rest can be coupled through a pocket slot (16) formed underneath the seat and designed to hold the free end of the lever arm (12a).
