No. 794,924 Claims priority, application Denmark Feb. 24, 1953 7 Claims. Ci. Bi -357) This invention relates to upholstered articles of furniture provided with a seat and a back such as arm chairs and sofas.

Most arm chairs and other upholstered articles of furniture have proved to possess the quality that while some persons feel comfortable in the arm chair and get the necessary support Where this is required, other persons rest less comfortably in the same chair because they do not get the same effective support of the necessary parts of the body as the first mentioned category of persons.

An object of the present invention is to provide an arm chair or other upholstered article of furniture provided with a seat and a back, which furniture is adjustable in adaption to different persons so that the number of persons finding rest and support in the same arm chair is virtually increased.

A further object of the invention is to provide an upholstered article of furniture having a seat and a back, by which the latter comprises at least two side frame members and a back support or back cushion made as a separate upholstered unit and at its upper part being pivotably connected to said side frame members while the lower end of said back support is adjustable in the transverse direction of the back.

Hereby is obtained that the back support can be ad justed in the longitudinal direction of the seat and thereby the length of the seat may be adapted to the length of the thighs of the legs of the persons who are going to sit in the article of furniture. This is of great importance since it has shown up that hereby is obtained that all the parts of a body which ought to be supported for obtaining the best possible rest and support in an arm chair or the like, is given the necessary support which is not possible, however, if the thighs of the legs are essentially shorter or longer than the length of the seat.

Various other objects and advantages of the present invention will be apparent from the following description of some embodiments of the invention.

In the accompanying drawings- FIG. 1 is a perspective view partly in section of an arm chair embodying the invention,

FIG. 2 is a fractional vertical sectional View of the chair frame of the arm chair shown in FIG. 1, without upholstering, and showing only the parts of the frame connected to the back of the chair,

FIG. 3 is a rear View of the chair frame shown in FIG. 2,

FIG. 4 is an enlarged fractional sectional view of the lower part of a frame of a back support, taken on the line 4-4 in FIG. 3,

FIG. 5 is a perspective view partly in section of an adjustment rod,

FIG. 6 is a front elevation of an adjustment fitting, and

FIG. 7 is an enlarged fragmentary vertical sectional view corresponding to a sectional view taken on the line 7-7 in FIG. 3, but showing a further embodiment of the connection between a side frame member and the upper part of a back support.

The arm chair shown in FIG. 1 comprises an upholstered seat 10, upholstered arm rests 12 and a back combined by an upper neck cushion 14, side members 16 Federated July 31, 1962 and a back support or back cushion 18 arranged between the side members 16 and below the neck cushion 14.

All stated parts of the chair are upholstered. In the embodiment shown, the seat 10 and the back support 18 are upholstered by means of no-sag springs 20, a layer of foam rubber or the like 22 and a cover 24, the arm rests and the side members 16 by means of foam rubber or the like covered by a cover, and the neck cushion 14 by means of a piece of hessian 26, covered by for example crimpy wool 28 again covered by a layer 30 of foam rubber covered by a cover 32.

The back support 18 is made as a separate unit which is upholstered independent of the further parts of the chair. Not before the neck cushion 14, the side members 16 and at least the rearmost part of the seat 10 having been upholstered, the upholstered back support 18 is in the manner described below arranged in the opening defined by and between the neck cushion 14, the side members 16 and the seat 10.

The above stated upholstery is arranged upon a chair frame which is shown in FIGS. 2 and 3.

The back frame comprises two side frame members 34, each continuing at the bottom into a longitudinal seat frame member 36. The side frame members 34 which support the upholstery of the side members 16 are at their lower ends interconnected by means of a transverse frame member 38 to which the rear legs 40 of the chair are secured. At their upper parts the side frame members 34 are interconnected partly by means of a curved frame list 42, partly by means of a traverse 44. The piece of hessian 32 of the upholstery for the neck cushion 14 is stretched between the frame list 42 and the traverse 44, the foam rubber layer 30 and the cover 32 are secured to the lower side or the rear side of the traverse 44 as well as to the rear side of the frame list 42 from which only the cover 32 continues downwardly to the transverse frame member 38 to which it is secured, so that the cover covers the rear side of the chair.

As appears from FIG. 1 the seat frame members 36 are interconnected also at their front ends by means of a traverse 46 to which the front legs 48 of the chair are secured.

The side frame members 34, the transverse frame member 38 and the traverse 44 define between them a square opening, see FIG. 3, within which the back support 18 is arranged.

The back support 18 comprises a frame consisting of two side frame bars 50, at the top interconnected by means of a curved transverse frame bar 52, and at the bottom interconnected by a transverse frame bar 54.

When the back

support frame 5t

52, 54 has been upholstered, it is inserted in the opening 43 and at its upper part pivotably connected to the side frame members 34. For this purpose, in the embodiment illustrated in FIGS. 1 to 6 a pivot pin 56 is from the inner side of each side frame bar 50 through a previously formed through hole 58 in the side frame bar 50 pressed into a likewise previously formed hole 6t) in the adjoining side frame member 34.

At its lower end the back support 18 is adjustably connected to the

back frame

34, 38, 42, 44-, preferably by means of an adjustment device which can be set by the person who is going to sit in the chair.

In the embodiment shown in FIGS. 1 to 6 this adjustability is obtained in the following manner:

On the rear side of the lower transverse frame bar 54 an adjustment rod 62 is arranged displaceably in its transverse direction and extending in the longitudinal direction of the transverse frame bar 54. The rod 62 is guided in longitudinal holes 64, see FIG. 4, in the two side frame bars 50 through which holes 64 the rod 62 is passed. The rod 62 extends at either side of the back spa /333s support frame, and each end thereof is in its lower position able to engage a fitting 66, see FIG. 6, secured to the inner side of the adjoining side frame member 34, preferably in a short distance from the inner side of the latter. The upper edge of each fitting 66 is provided with a number of notches, in the embodiment shown with two

such notches

68 and 70, one of which the adjoining end of the rod 62 engages when the rod assumes its lower position.

The rear notch 68 is found by a vertical rear edge '72 and a front edge 74 which is inclined upwardly and forwardly. When the rod 62 engages the rear notch 68 will abut the vertical edge 72 and thereby prevent a displacement of the back support 18 rearwards. Provided now the back support 18 is drawn forwards, for example thereby that a hand is pressed into the space between the seat and the lower edge of the back support 13, said lower edge is gripped by the fingers, and the hand then is moved forward, the rod 30 will move upwards along the edge 74 of the notch 68 out of engagement with this notch. After a short further forward movement of the back support 18, the rod will engage the following notch, which in the embodiment shown is the foremost notch '70. This notch is at the rear side as well as at the front side bound by

vertical edges

74 and 76 respectively, so that the back support 18 is securely held in its foremost position defined by the foremost notch '70.

When later on the back support 18 has to be swung backwards to its rearmost position it is necessary to lift the rod 62 out of engagement with the notches 70. This may be done by the fingers of a hand being put in under the back support 18 into engagement with the rod 62, which then is pushed upwardly.

For facilitating this operation, as appears from FIGS. 2 and 4, the rear side of the transverse frame bar 54 is approximately at the middle thereof provided with an incision 80 extending upwards from the lower edge of the frame bar 54 to register with the rod 62. Thus, when the fingers are put in under the back support 18 opposite the incision 80, there will be no difiiculty in reaching and operating the rod 62' by means of the finger tips.

Further, as appears from FIG. 5, the adjustment rod 62 is provided with a cover 82 made for example of a plastic or rubber and on the outer side provided with longitudinal ribs 84. Hereby is obtained, partly that the fingertips will not slide upon the rod, partly that the rod causes no noise.

When the rod 62 is pushed upwards out of engagement with the vertical edge '70 the back support 18 can be swung backwards to its rear position defined by the engagement of the rod 30 with the rear vertical edge '72.

Also the upper part of the back support 18 can be yieldingly supported as appears from FIG. 7. In this embodiment an angleiron 120 is secured to the inner side of each side frame member 34 with a flange 122 projecting inwardly. A forwardly extending bolt 124 is secured to the flange I22 and extends through a hole 126 in an inwardly extending flange 1.28 of an angle-iron 130 secured to the inner side of the adjoining side frame bar 50 of the frame of the back support 18. A nut 132 on the outer end of the bolt 124 prevents the flange 128 from falling off the bolt 124. Between the two flanges 122 and 128 a spring 134 is inserted surrounding the bolt 124. By this supporting device the back support 18, although pivotally connected to the side frame members 34, is able yieldingly to be displaced forwardly and backwardly even at its upper end.

It will be understood that various changes in the details and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
