Application November 5, 1956, Serial No. 620,357

2 Claims. (Cl. 155-106) This invention relates to articles of furniture or seating units adjustable from the sitting position to a more or less reclining position. It is particularly directed to a construction which is adapted for use in an upholstered piece of furniture having stationary arms and an upholstered seat cushion which may be tilted without interference with the arm structure. For example, in upbolstered chairs, what is known as a T-cushion, is often used on the seat which has a T-shaped front portion extending beyond the arms, both towards the front of the chair and laterally. When a seat or cushion of this shape is mounted for tilting movement it must clear the corners of the arms and if the front surfaces of the arms are vertical or slightly forwardly inclined, as insome designs, the seat and its cushion must move slightly forward during the upward swinging movement thereof so as to be given an arc of movement which will enable the T-shaped extensions to clear the arms.

It is an object of the present invention to provide a construction in which this result is accomplished. It is a further object of the invention to provide a construc-' tion of the above character which is provided with a leg rest connected to the article of furniture in such manner that it is projected to a leg supporting position when the back rest and seat are swung to a reclining position and is retracted when the seating elements are moved to up right position.

In the accompanying drawingswhich illustrate certain preferred embodiments of the invention:

Figure l is a perspective view of a chair embodying one form of the invention and showing the seating elements of the chair in their reclining position;

Figure 2 is a side elevation of the chair shown in Figure 1 in an upright position;

Figure 3 is a view similar to Figure 2, showing the chair in a half reclining position;

Figure 4 is a side elevation of a modified form of chair in an upright position;

Figure 5 is a side elevation of the chair shown, in Figure,4 in a reclining position;

Figures 6 and 7 are views similar to Figs. 4 and 5 showing another modification of the invention.

Referring to the drawings in detail, the chair shown in Figures 1, 2 and 3 comprises a frame 20 having arms 22 which include side members 24. The front walls of the arms are shown as having vertical surfaces 26. The chair is shown as having a back rest 32 and a seat 34. The back rest is pivoted to the frame at points 36 some distance above the bottom of the frame and the seat has extension lugs 38 which are pivoted to the back rest 32 at pivot points 40 which are below the points 36 where the back rest is pivoted. The forward part of the seat is supported on seat guide links 42 which are pivoted to the seat at 44, the lower ends of the guide links in the construction shown in Figs. 1, 2 and 3, being pivoted at 46 to guide members or plates 48 which are pivoted at points 50 to the frame. The guide members 48 are pivoted at points 52 to thrust links 54 which United States Patent 2,371,918 Patented Feb. 3, 1959 edge and will also be pushed bodily forward owing to the fact that it is pivoted to the back rest below the pivotal axis thereof. In .the present instance the seat is shown as having T-formation to the front thereof including T-extensions 58 which extend laterally of the front surfaces 26 of the chair arms. With the construction shown it will be seen that the rear surfaces of the T-extensions will move upwardly along the curved path as indicated by the broken lines 64 in Figs. 2 and 3 so that the -T-extensions of the seat will move away from the surfaces of the arms and clear the upper corners thereof. This construction permits the front surfaces of the arms to be vertical or even to project slightly and thereby to conform to features of design which may be desired.

The back rest and seat construction described is desirable in securing a proper movement of the seat whether the article of furniture is provided with a retractable leg rest or not. However, the use of a retractable leg rest is highly desirable in reclining articles of furniture and the present invention provides a linkage for mounting and operating such a leg rest which is particularly designed for use in connection with the other features of the construction described.

In the form of the invention shown in Figs. 1, 2 and 3, the leg rest 66 has attached to it

links

68 and 70 which are pivoted to the leg rest at spaced locations of the width of the leg rest from front to rear. The seat has operating links or levers 72 pivoted thereto at points 74, in rear of the T-extensions 58, the ends of the long arms of these operating links or levers being pivoted at points76 to the ends of links 68. The operating links orlevers cross the links 70 to which they are pivoted at points 78. The rear ends of the links 70 are pivoted at. 80 to links 82. The operating links or levers 72 have short arms 84 which are pivoted at 86 to the upper ends of control links 88 which are pivoted at 90 to the lower corners of the guide members or plates 48. The rear ends of the links 82 are pivoted at 92 to intermediate portions'of the control links 88. When the chair is tilted back the linkage described will cause the leg rest to be raised and projected forward as shown in Figure 1. Where the linkage is used with a seat construction having T-shaped extensions, the rear portions of the operating levers '72 are given a depressed or concave curvature as shown at 94 so as to pass under the T-extensions without contacting the same.

It will be observed that the leg rest is carried on what may be termed a lazy tongs comprising two sets of related links. One set of the links comprises

links

68 and 72 pivoted to each other at 76 and the other set of links comprises the

links

70 and 82 pivoted to each other at 80. The leg rest is mounted on the

ends oi links

68 and 70. Only links 72 of the first set are pivoted directly to the seat. The second links 82 of the second set oftlinks instead of being pivoted directly to the seat asis the practice in certain prior constructions, are pivoted to the control links 88 which transfer lifting force from the seat and back rest organization to the lazy tongs construction through the links 82. This gives a different operating movement to the leg rest than that which occurs when the leg rest lazy tongs linkage includes two sets of links connected directly to the seat.

Figures 4 and 5 show a modified form of the linkage for supporting the leg rest. The stationary frame, seat and back rest, and the linkage for operating the seat and back rest are the same as in the construction shown in Figures 1, 2 and 3. In this construction, however, the links 88a for transmitting movement to the leg rest operating levers are pull links instead of thrust links as in the previous construction and are connected to extensions 84a of the operating levers 72a which are not bent back as are the short arms 84in the previous construction but extend beyond the pivot points 74. The lower ends of the pull links 88h are' pivoted to the guide members 48a at points 90a,which are between the points 50 where the members.48a.are pivoted to the chair frame and the points 52a where, thrust links 54 are pivoted to the guide members. The relative movement between the points 52a and'thepoints 74 due to the for ward and upward movement of the chair seat results in pulling force being applied to the links 88a when the chair members are moved to a reclining position. In the present construction also ,the leg rest supporting links 70 are pivoted to links 82a which are not connected to the pull links 88a but are pivoted at points 92a on the seat.

In the construction shown in Figures 6 and 7 the back rest, seat and their connections with the frame are the same as already described. Linkage for supporting leg rest is also the same as that shown and described in connection with Figures 4 and 5 except that in this construction the pull links 8812 are not pivoted at their lower ends to the guide members 48b but are pivoted at points 96]) directly to the stationary chair frame. As the seat moves forward and upward the links will pull on the short arms 84b of the leg rest operating levers 7212 so as to project the leg rest as before.

I have described preferred embodiments of my invention, but it is understood that this disclosure is for the purpose of illustration, and that various omissions of changes in shape, proportion and arrangements of parts as well as the substitution of equivalent elements for those herein shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
