1 Claim. (Cl. 297--35)
The present invention relates generally to new and
useful improvements and structural re?nements in fold
ing and collapsible chairs and is directed particularly to
a folding chair having arm rests interconnected with the
other chair components in manner whereby same may be
moved into and out of the folded or collapsed or non
operative position simultaneously with corresponding
being recognized as entirely possible within the scope and
15 spirit of the invention.
In the accompanying drawings, selected embodiments

The invention resides in the particular construction,
arrangement, combination, and relationship of the various

are as follows:

known. Supporting rear legs 4 of a pair are each inter
front leg, a pair of arm rests pivotally connected to the
brackets by means of a pair of forward supports and 45 connected with one of the front legs 2 of the pair thereof.
A seat frame 6 is disposed between the spaced front legs
pivotally connected to the rear legs by means of a pair
2 and the spaced rear legs 4'. The back 8 is ?xed to the
of rearward supports for causing the arm rests to swing
generally curved intermediate or yoke portion of the in~
upwardly in unison into the normal plane of the main
frame when the chair is in folded position.
Another object is to provide a seat which is independ
ently collapsible.
Another object is to provide a chair having front and
rear legs and a foldable seat with means being provided
for supporting the seat when same is in the extended
position and for operatively engaging the seat when the
chair is moved into the collapsed position.
Broadly stated, the invention envisions in general a
chair having a main frame, the lower ends of which pro
vide front legs for the chair. Rear legs are pivotally
linked to the main frame at the sides thereof. A seat is
pivotally mounted upon a seat bracket disposed on each
side of the seat, each seat bracket being pivotally con
nected to the respective adjacent front leg and rear leg,
it being noted that the seat is directly pivoted neither
verted U-shaped main frame. Arm rests 1-0 of a pair
thereof are disposed at opposite sides of seat frame 6 and
upwardly thereof when the chair is in the conventional
open or operating or seating position.
The seat, back and arm rests of the chair may be pro
vided with appropriate and conventional padding mate
rial or upholstery ‘11 for the increased comfort of the chair
The legs, seat, arm rests and back preferentially will
be formed from light-weight metal stock which is easily
shaped, although the chair may be fabricated from other
materials, if desired, without departing from the spirit or
scope hereof.

otally interconnected by guide links 12 with each guide

a related front leg at 14, substantially as shown, whereby
said front and rear legs may be folded or collapsed as to
each other.

By the application of continued pressure, the seat
brackets are moved from the generally horizontally-dis

vertically-disposed position shown in F168. 4 and 5.
Itis to be appreciated that the seat may be independ
ently placed in the raised position or collapsed, without
the collapsing of the other chair components, the seat
being pivoted only to the seat brackets 16, as aforesaid.

Each seat bracket 16 is disposed relative to the front
and rear legs at the respective sides of the chair and is
pivoted approximately centrally thereof to said front leg

It will be thus appreciated that the seat is not directly

Changes may be made in the form, construction and
arrangement of the parts without departing from the
spirit of the invention and/ or sacri?cing any of its advan
tages, and the right is hereby reserved to make all such
changes as fairly fall within the scope of the below
appended claims.
It is believed that the advantages and use of the inven
tion will be clearly understood from the foregoing dis
closure and accordingly, further description thereof at this
point is considered unnecessary, as I have, in accordance
with the provisions of the patent statutes, described the
principle of operation of my invention together with the
apparatus which I now believe to represent the best em
bodiments thereof.
The below claims are desired to include, within the
scope hereof, all suitable variations, modi?cations and
equivalents by which substantially the results of the in
vention may be obtained through the use of substantially
the same or equivalent devices or means.
