CHAIR.

Application filed January This invention relates to improvements in chairs, and has particular reference to that type of chair commonly termed an easy chair.

The principal object of thisinvention is to provide means whereby the side and back will automatically adjust themselves so as to be comfortable irrespective of the position to which the back is inclined.

Another object of this invention is to provide means for raising the seat and at the same time the back is moved.

A further object is to provide means whereby the seat may be rocked. upon a pivot, which pivot is at all times held in a fixed position with relation to the back, irrespective of the inclination thereof.

Other objects and advantages will be ap parent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are used todesignate like parts throughout the same,

Figure I is a side elevation of a chair con structed in accordance with my invention, and with one side thereof removed, and

Figure II is a view similar to Figure I showing the back and seat in reclining position.

It has been common to construct easy chairs wherein the back could be moved into a reclining position. It has also been common to provide chairs wherein the back and seat are moved in unison, retaining thesame angles between the seat and back. My in-. vention, however, contemplatesthe idea of a back and seat, both of which are movable in unison and at the same time providing means whereby the seat may be adjusted relative to the back.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the chair frame as a whole having

legs

6 and 7 and

cross braces

8 and 9. A frame is shown at 11, upon whcih frame the seat ordinarily rests. This seat is designated by the numeral 12 and has a bottom frame 13 which is adapted to be attached to a lever 14. At 16, I have shown a back cushion which is attached to a 2, 1926. Serial No. 78,993.

back frame 17, which frame is pivoted at 18 to the chair. The back frame carries a lever 19 which extends downwardly and under the seat 12 in such a manner as to be pivotally engaged as at 21 to the lever 14.

The

numerals

22 and 23 refer to links which are. pivoted together at 24 and are in turn pivoted to the chair frame as at 26 and to the pivot 21. A spring 27 is secured to the

links

22 and 23. This spring tends to normally retain. the parts in the position shown in Figure I, and when stretched to the position shown in Figure II, tends to counterbalance the weight placed upon the back 16. The

links

22 and 23 when extended to the position shown in Figure II serve to limit the extent to which the back frame 1? may be expanded.

The chair operates in the following manner:

A person sitting upon the seat 12 may lean against the back cushion 16 and remain in this position if he so desires. By slightly increasing the pressure upon the back, the back will tend to incline further to the rear which inclination will in turn transmit motion through. the lever 19 to the lever 14, thereby raising the seat 12. This seat may rest in a horizontal position as shown in full lines in Figure II, providing the occupant wishes to stretch out, or the seat may be tipped at an angle as shown in dotted lines in Figure II if the occupant wishes to maintain a sitting reclining position.

It will thus be seen that the seat and the back automatically adjust themselves to any of the whims of the occupant, thereby providing a chair which may be readily adjustable and comfortable at the same time.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes relative to the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I

claim In a chair a frame, a back pivoted to said frame, a seat positloned in said frame, a lever secured to said back, said lever having ()FFICE.

a curved lower extremity and adapted to terminate at a point substantially beneath the center of said seat, a lever extending down- Wardly from said seat, said lever being angularly disposed With respect to said seat and having pivotal connection with said first mentioned lever, a pair of pivoted links interposed between said chair frame and the pivotal connection of said levers, a spring secured to said links upon opposite sides of 10 their pivotal connection one to the other.

In testimony whereof I afiix"n1y signature.

JOSEPH VETCHIK.
