This in-vention relates to furniture, and the upturned ends 16 of the front-. a'-xicl - rear more particularly to a folding chair whielt strips 10 dnd 11 by pivot pins 11; In o:rder: easily-collapsed int6 a' to form a rigid the lov@er leg may be quidkly and @UpRort for siia all vertical space when not clesired for use6 r. One objeci of this i@avention is to provide a folding chair 6f the above nature ' which is adapted to be collapsed by the action of swin9mg tho,.back resf for'wardly. A Lri'her object is to provide a, corapsible Ita chair of the ab@ove- nature in -v@hich the seat and back rest are adapted to drop by gravity into collapsed position upon th6 floor after th.e back rest has, been sw@iig forwarclly.

A @ further object- is to rovide a folding' cb,air of the above nature tlii@h will b6 -relatively simple in coiastruction, inexpensive to manufacture, easy to manipulate, ornameiital in appearance, and very efficient aDLd.durabl6 in use.

This wil.1 causi@ the connecting link 41 to move forw@ti,dly foreiiig the pivot pins 20 of the foi-wa-i-d leg sections to niove rearwardly. 2.0 At the sanie tiiiie, the jointed links 43 and 44 will be pulled rearwardly forcing the upper rear leg sections 21 to rotate in a clockwise direction ab6ut'their pivot pins 22. ' This will cause the central pivot'pins 20 of the 25 rear legs to move forwardly. The chair will thus beperinitted to collapse under its own weight and will assunie the position sl@owii iii dotted- lin6s in Fig. 2. The shock of the fall is absorbed by a pair of bumpers 45 of rub'io ber or other resilient material When it is desired to unfold the e.hair, all that is iiecessary is io lif t the seat 23 upwardly, and then swing the back rest 34 rearwardly uintil the jointed legs assume the open posi35 tion shown in Figs. 1. and 3. Iii the modifiecl form of the invention sbown in FiLy. 4, the chair is provided with lockin(r mecl@anism. for preventing th6 baek from being swuiig forwardl uiatil- the op4o erator desires to collapse t&l chair. This mechanisni c,omprises a pair of arms 46 pivoted to the rear upper leg sections 21 by pins 47, and beiiig provi-ded with forwardly ex,tending angular slots 48, having upturned dr) front ends 49 for slidably receiviilg locki@he, lugs 50. While the pr'esent inveiition is adapted for general use.wherev ' er a collapsible chair which folds up into a small vertical spa, is e 50 desired, it will be found particularly, useful in auditoriums, su6h as rnotion picture tlieatres where there is a larcre fire risk. In case of &e, the handles 51 a the loclcing levers ,"rill be pulled up, whereupon the chairs ma 55 be cohapsed flat upon the floor by pullino, the baclcs forwardly tliereby aff4DrdiD(y th6 @udience an unobstructed path to th@'exits.
