1 claim. .(l. 155-111) This invention relates to chairs and has for its object to provide a reclining type chair which is self-adjusting vin response to the movement l of the occupant. `Another objectis to provide a f device of this sort which has the seat portion pivotally connected to the tilted back so that the seat may be moved forwardly and rearwardly as the inclination of the back is adjusted. A further object is to provide a simple and inexpensive lo device of this sort which may be easily adjusted with little friction. Yet another object is to provide 'a pivotal connection between the seat and back which may be loosened or tightened by the occupant while sitting in the chair.
Referring to the drawings: Fig. 1 is a, side elevation of a chair embodying this invention.
Fig. 2 is a section on the li'ne 2-2 of Fig. 3. Fig. 31s a top plan view of the chair of Fig. 1. m Fig. 41s a detail of the antifriction support Vand guide, and end portion of the seat.
Fig. 5 is a front view partly in section of the pivotal connection between the seat and back.
Fig. Q is a right side view of the device of 25 Fig. 5.
In Fig. 1, the chair comprises a back portion il, having slats II, or other customary construction, which is pivotally supported at 'I2 at the rear of the arms I'I. A seat I3 is pivotally con- 30 nected at I4, to the lower end portion of the back below its support I2. The front legs I5 and the rear legs I8, may be of the general shape indicated. For supporting the arms I1 and back,
braces or props i6' are provided. Suitable trans- 38 verse braces I 9 and 20 reinforce the under-frame.
A metal brace shown by dotted lines in Eig. 1
connects the brace I6, rear legs I3, and the support or pivot I2. A leg and foot rest 2| is pivotally connectedat 22 to the front portion of the 4 seat, and is provided with a supporting` member 23, which is adapted to rock about its lower end,
as the seat I3 is moved forward and backward with changes in the inclination of the back.
A metal strip 24' is secured to the front por- 4l tion of the seat as shown in Figs. 2 to 4, inclusive. A cross or transverse brace between the upper forward ends of the rear legs i3 supports an element having an arcuate anti-friction surface 23. Ihis member having such arcuate' sur'- I. face 26, is screwed or otherwise secured to this cross brace as indicated. though, if desired, it
. may 'be made integral with the upstanding guide 23 which is secured by screws entering the holes bearing may be used. The strip 2d is secured to the forward portion of the seat'by the upstanding post 21 through which a screw is passed transversely of the seat, and also by a screw passing through the hole 23 into the forward portion of the seat. As shown in Figs. 2 to 4, inclusive, the metal strip 24 takes up` the wear of sliding movement-of the seat and the guides 29 prevent any lateral shifting of the seat, especially in the forward portion. The guides 29 not only engage 10 the sides of the metal strips 24, but also have' overhanging portions 29a which prevent the seat Through this'metal fitting which is secured to the back by screws as indicated, is a recess for reception of the pivot pin I4, which, in this case, 20 includes a flat headed bolt 33 which passes through the upstanding projection of member 34, which is secured to the seat. A nut 35 is threaded on the end of the bolt opposite its head, so that on tightening the screw |4, the ttin 3| -is clamped tightly between the seat supporting member 34 and the nut 35. A projection or wing portion on the nut constitutes a finger piece by means of which the nut may be tightened or loosened to control the ease of adjustment between the back and seat. The movement of the inger .piece 38 to the left in Fig. 6 effects a tightening or clamping of this pivotal connection so tha't. the back and seat may be maintainedin whatever adjusted position is desired. A washer 31 is placed between the litting 3| and the supporting member 34 for the seat. It will be understoodv the clamping mechanism illustrated in Figs. 5 and 6 may. if desired. be used on both pivotal connections. be- 40 tween the back and seat, although'in the embodiment illustrated, this connection is located only on one side, as shown in Fig. 3.
In operation, the occupant may slt in the chair in any position of its adjustment, and-after be- .ing seated, control the inclination of the back to whatever position is desired. By moving the finger piece 33 to loosen the nut 3l, this pivotal connection between the back and seat may be loosened so that the back and seat maybe ad- 5'0 justed to whatever position is desired by merely conforming the body to the desired position. As the back is inclined rearwardly, for example, to the dotted line portion shown in Fig. 1, the seat I3 is moved forwardly. The finger piece 33 is conveniently manipulated by the chair occupant without dimculty. Instead of having the adjustable locking device applied to the pivotal connection I4, it will be understood that it may be located elsewhere, such for example, as at the pivot I2. The advantage, however, of locating this locking device in the pivotal connection I4, resides inthe ease with which it may be manipulated by the chair occupant who can conveniently tighten or loosen this device, with one hand, whereas it would be less convenient to control iflocated elsewhere. If the leg rest 2| is raised in the position illustrated in Fig. l, it will be understood that this constitutes an extension of the seat and must also be shifted forwardly as the seat moves with the rearward tilting of the back.
From the drawings it may be seen the pivotal centers of the arms, legs and seat are so spaced that the chair may be folded by moving the back toward the seat and collapsing the quadrangle formed by the brace I6, legs I8, upper portion of the front legs I5, andthe arms I1.
Iclaim:
A folding chair comprising connected side frames, each frame including an arm rest, a for- Wardly4 inclined front leg pivoted to the front end portion of the arm rest, a rearwardly inclined rear leg pivoted to the'front leg intermediate the ends thereof, a. rearwardly inclined brace pivoted between the rear ends of the arm rest and rear leg; a back rest pivoted intermediate its ends to the rear end portion of the arm rests, a seat pivoted tothe lower end of the back rest, said seat comprising a frame and spaced longitudinal slats therein, means slidably supporting and guiding the front end ofthe seat comprising a cross bar connecting the upper ends of the rear legs, vtransverse metal members having convex upper surfaces on the ends of said cross bar, metal 'plates on the under side of the seat sliding over the metal members, said metal plates extending inwardly beyond the inner edge of the side .bars of the seat frame and guide members secured to the cross bar and having vertical hooks extending over the inner edges o said plates.
