Abstract
A chair with a back arrangement employing a back shell slidably supported on a pair of uprights projecting upwardly from opposite sides of the chair seat.

The chair additionally incorporates an adjustment mechanism which allows manual adjustment of the chair arms into the desired position.
Claims20
A chair having a seat, a pair of stationary supporting parts positioned adjacent opposite sides of the seat, and an arm assembly mounted on each of said supporting parts for raised disposition adjacent one side of the seat, the arm assembly comprising:
- a horizontally elongated arm rest having an upper surface disposed for contact with an occupant's arm;
- a support disposed under said arm rest and supportedly engaged with the respective supporting part;
- a swivel connection cooperating between said support and said arm rest permitting the arm rest to be vertically swingably moved through a small angle between lowered and raised positions, the swivel connection permitting the arm rest when in the upper position to be horizontally moved between at least two use positions spaced apart by a small horizontal angular extent;
- and
- a releasable lock cooperating between said arm rest and said support to lock the arm rest against horizontal swinging movement when the arm rest is in the lowered position and is in either of said two use positions.
An adjustable chair arm assembly, comprising:
- a horizontally elongated arm rest having an upper surface for contact with a chair occupant's arm;
- a vertically elongated support projecting downwardly from said arm rest adjacent a rear end thereof;
- a swivel connection joining said arm rest to said support for permitting both horizontal and vertical swinging movement of the arm rest through small angular extents;
- and
- a lock mechanism coacting between said arm rest and said support to prevent horizontal swinging of said arm rest when it is in a lowered horizontal position and being released when the chair arm is in a vertical position.
A chair comprising:
- a seat;
- a pair of stationary uprights projecting upwardly adjacent opposites of the seat;
- a back supported by said pair of uprights and projecting upwardly adjacent a rear edge of said seat, said back having a pair of support sleeves on opposite sides thereon positioned in surrounding and supportive engagement with said uprights;
- an arm assembly mounted on each said upright, each said arm rest assembly including a vertically elongate support post which is telescoped in a said upright and projects upwardly therefrom and at its upper end is connected to a horizontally elongated arm rest having an upper surface for contact with a chair occupant's arm;
- a position adjusting mechanism cooperating between the support post and arm rest for permitting the arm rest to be horizontally laterally adjusted into one of a plurality of positions, said mechanism providing a positive locking of the arm rest in the selected position;
- a height adjusting mechanism cooperating between the post and the respective upright for permitting the height of the arm rest to be selectively varied;
- and
- an activating trigger carried on said arm rest assembly and interconnected to said height adjusting mechanism for permitting activation thereof.
