Office chair

A mechanism for mounting the seat of a swivel chair to the chair frame, with a first mounting which can be connected to the frame, with a second mounting carried by the first mounting via a joint, which can be connected to the seat and with a spring arrangement for the initial tensioning of the second mounting in an upper position of rest, locking parts on said first and second mounting which are adapted to be engaged and disengaged by a locking slide.

One-piece seat shell

A frame for use in a cantilever chair comprises vertical pose portions (12) connectable to a seat shell (24). Base portions (36) are connected to points of the post portions (12) lying above the lower ends thereof, the base portions (36) thus being sloped in downward direction. Thus the base portions (36) do not engage the floor (34) along their entire length and provide for additional spring action under load conditions.

Seat

An office chair in which a backrest and seat are articulated together and the resulting assembly pivotally suspended from the rear end of the side arms which form a pivot point positioned at or near the center of gravity of the chair when occupied. The pivot point is fixed in space by an underlying support system. The lower end of the arm rest is affixed to the rear transverse support arm of a support frame which is, in turn, mounted on the upper end of a vertical support column. The front end of the set member is slidably mounted on a forward cross arm of the support frame through a hexagonally-shaped sliding/locking member in such manner that the back rest and seat may be selectively locked in position or released to adjustably recline (backrest) and slide (seat). The articulated connected between the back rest and seat member is positioned beneath and rearwardly of the aforementioned point of pivotal suspension, so that when the back rest is tilted rearwardly from an upright position the rear portion of the seat member is caused to lower slightly as it slides forwardly. All controls for the chair are located on either end of the aforementioned support arm.
