초록 ▼

A chair, in particular a work or office chair, the seat of which is variable in inclination and is pivotal in the forward region about a horizontal pivot shaft. A backrest is mandatorily, disproportionately variable in inclination as a function of the change in seat inclination. With increasing inclination of the seat, the backrest approaches the rear end of the seat. The pivot shaft of the seat is limitedly adjustable both downward and toward the backrest on the bearing block of the chair pedestal. The seat is pivotally connected to pivot levers, one end of each of which is fixedly attached and nonrotatably with respect to the backrest and the other end of each of which is rotatably supported on the bearing block. Synchronous motion with relative motion between the seat and backrest is achieved with an adjustment mechanism disposed only beneath the seat. This mechanism is characterized in that the pivot levers are pivotally attached to the seat, spaced apart by approximately one-fourth the depth from the rear end of the seat. The ends of the pivot levers oriented toward the back rest have two segments located at approximately a right angle to one another. The backrest is firmly connected to the segments forming the free end of the pivot levers or is connected to them in a vertically incrementally or infinitely adjustable manner. The opposite ends of the pivot levers are pivotally attached to the bearing block approximately beneath the middle of the seat and are at an obtuse angle of approximately 150°to 170°, facing toward the floor, from the adjoining segment of the pivot levers.
