Patented Apr. 14, 1953 OFFICE RECLINING CHAIR Harold Fischer, Waterloo, Ontario, Canada Application March 26, 1951, serial No. 217,559 In Canada March 25, 1950 This invention relates to chairs and more particularly to reclining chairs of the adjustable type.

An object of the invention is to provide a reclining chair of simple construction and convenient manufacture, and which is quickly and readily adjustable with a minimum of effort by the user to a variety of positions.

The invention will be described with reference to the accompanying drawing, in which,

Figure 1 is a plan view of a recliningchair in accordance with the invention,

Figure 2 is a side elevation,

Figure 3 is a detail sectional view on line 3-3 of Figure 2, and

Figure 4 is a detail sectional view on line 4 4 of Figure 2.

Referring to the drawing, the chair comprises a suitable base frame I having supporting legs 2. The frame I includes front and rear

transverse members

3 and 4 and side members 5. Arm frames 6 may be mounted on the base and include arms 6 supported `on front and rear vertically disposed members I and 8. Slidably mounted on the base is a seat frame 9 having the usual seat or cushion portion I0. As shown, the side pieces I I are slidably supported by means of slidable bars I2 fixed to the outer faces of the side pieces. Each slide bar I2 extends through a substantially horizontally disposed slot I3 provided in a plate I4 extending between members 'I and 8 at the side of the chair. It will be observed that the forward limit of sliding movement of seat 9 is determined by engagement of the forward ends of bars I2 with the members 'I while the rearward limit of sliding movement is determined by engagement of the rearward ends of bars I2 with members 8. Thus, the extent of such sliding movement is determined by the length of bars I2. Preferably, seat frame 9 is downwardly inclined from front to rear, as shown, for greater comfort in use.

A back rest frame I5, preferably provided with a cushion portion I 6, is pivotally connected to seat frame 9 as by a pair of pins or bolts II each of which extends through the lower end of a respective side piece I8 of the frame I5 and the rearward end of adjacent side piece I I of the seat frame. Each pin I'I also extends through a slide bar I2 and on its outer end is pivotally mounted one end of a link I9. The other end `of each link I9 is pivotally mounted on the outer end of a pin or bolt 20 which extends through an arcuate slot 2| in a vertically disposed member 22 mounted on plate I4 and suitably xed in the rearward por- 4 claims. (c1. 155-2116) Lll) tion of arm frame 6. The inner end of pin 20 is fixed in a respective side piece I8 at a point spaced considerably above the lower end of frame I5. Preferably, a roller 23 is mounted on each pin 20 for ease of sliding engagement with the Walls of slot 2|.

Means for urging the seat frame 9 in a rearward direction comprises a pair of springs 24 connected to the transverse member 4 and to the side pieces I I of the seat frame.

It will be observed that forward movement of the seat frame 9 will, through the linkage connection with the back frame I5 described, cause the latter to assume a lower or more gently inclined position, as illustrated in dotted lines in Figure 2, whereas rearward movement of the seat frame 9 will cause the back frame to assume a more upright position, as illustrated in full lines.

In use, as the sitter leans forward the seat automatically moves backward, the slide bars sliding back in the horizontal slots and the rollers sliding up in the arcuate slots to raise the back. The springs 24 assist this action. When the sitter leans back the action is automatically reversed to provide a more comfortable arrangement of seat and back. As previously indicated, the extent oi.' adjustment and the angle to which the user may recline is governed by the length of the slide bars I2.

There has thus been provided a reclining chair of simple structure which is readily and automatically adjustable to a variety of positions at the will of the user.

The frame of the chair may be formed of any suitable materials, such as wood or metal.

What is claimed is:

1. A chair comprising a base, a pair of laterally opposite members xed to the base and extending from front to rear thereof, each said member having a substantially horizontally disposed slot therein, a Vseat frame, means for slidably mounting the seat frame on the base including a pair of slide bars each xed to one side of the seat frame and extending through one of said slots, a back frame pivotally connected to the seat frame, and means for varying the inclination of the back frame in response to sliding movement of the seat frame including a vertically disposed member mounted on the base on each side of the back frame and having an arcuate slot therein, and a pair of links each having one end pivotally connected through said slide bar to the seat frame and the other end pivotally connected through said arcuate slot to the back frame.

2. A chair as dened in claim 1, including an 4. A chair comprisinga base, a pair of laterally opposite members xed to the base and extending from front to rear thereof, each said member having a substantially horizontally disposed slot therein, a seat frame, means for slidably mounting the seat frame on the base including'a pair of slide bars each xed to one sidev of the seat frame and extending through one of saidslots, a back frame pivotally connected to the seat frame,

and means for varying the inclination ofthe back frame in response to sliding movement of the seat 4 frame including a vertically disposed member mounted on the base on each side of the back frame and having an arcuate slot therein, and a. pair of rollers carried by the back frame and each having rolling engagement with one of said arcuate slots.
