Application led February 3, 1930. Serial No. 425,591.

My invention relates to improvements in chairs and the like and has for its object to provide a chair which will be highly beneicial to the user by permitting the body to assume a proper position necessary for complete relaxation and comfort.

A further object of the invention is to provide a chair, the body of which is pivotally mounted, so as to swing backwardly when a person sits in the chair.

Another object of the invention is to provide a chair of the above-mentioned character which is simple and durable in construction, reliable and eiiicient in use and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a0 a part of this specication and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a front elevation View of the improved chair,

Fig. 2 is a rear view partly in section,

Fig. 3 is a vertical section taken on lines 3 3 of Fig. 1, and,

Fig. 4f is a side elevation of the chair.

In the drawings, wherein for the purpose 3o of illustration, I have shown a preferred embodiment of my invention, the numeral 5 denotes the base which is a box like structure adapted to support the body of the chair. The body of the chair consists ci a back portion 6, arm portions 7 and seat portion 8. The width of the body corresponds to the inside width of the base and the body is pivotally supported above the base by hangers 9 iixedly attached to the inner face of the sides of the base, the upper ends of the hangers projecting above the base and pivotally connected to the arm portions 7, as at 10. The body is pivotally mounted off center, so that when a person sits in the chair it will automatically swing backwardly, as shown in Fig. 4. To retard the backward movement of the body a series of iiat steel springs 11 are disposed within the base beneath the seat of the body. The springs are bent V-shape having one end secured to the 4bottom of the base by clamps 12, theopposite arm being inclinedupwardly towards the rear of the seat portion of the body,"the upper extremity of the arms engaging ben neath the rod 13 extending transversely i5` across the bottom of the seat. The rod is secured` to the bottom of the seat by brackets 14 and has its ends extending through the arcuate slots 15 in the sides of the base, binding nuts 16 being threaded on the ends of 60 the rod to secure the body in any position desired. The backward movement of the body is limited by the blocks 17 secured to the inner faces of the sides of the base, the blocks being provided with an inclined end G5 1S against which the bottom of the seat abuts, and shock absorbing springs 19 are disposed in recesses 20 in the end of the blocks to absorb the shock when the body swings back. The back wall of the base is provided with a swinging door 21, through which access may be had to the inside of the base when desired. The opening between the body and base at the back of the chair is covered by a sheet of flexible material 22 hav- 75 ing one end secured to the back of the body and the other end secured to the back wall of the base.

A panel 23 depends from the front end of the seat portion 8 and in its front face is provided with a recess 24 in which the foldable foot rest 211 folds when collapsed. Shock absorbing springs 25 are seated in notches 26 in the rear face of the panel 23, adapted to Contact with the front wall of the base when the body returns to its normal position.

The seat portion 8 at its forward edge is provided with raised portion 27 to support the knees. The back portion 6 at its sides is provided with wings 28 and between the wings is an adjustable head rest 29, suspended from the ends of cords 30. The cords extend through lopenings 31 communicating with the recesses 32 and have their opposite Ui ends connected with coil springs 33 disposed in the recesses, which permit the head rest to be readily adjusted.

In use, it will be seen that when a person sits in the chair the body will swing back- LGO wardly being retarded in its movement by the springs 11 and if desired the body may be secured in any position desired by tightenin the bindingnuts 16 on the ends of the 5 r 13. Y

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 certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claim;

Having thus described my invention, I claim A device of the character described comprising a box-like base open at the top, a body rockably mounted on said base, a series civ-shaped dat springs disposed in said base, and a rod extending across the bottom `y of said body, adaptedto slide along the upper armsfof said springs. K

a In testimonyv whereof I aiix my signature.
